Abstract

Practise-related transient abdominal pain (ETAP) is more than ordinarily known to athletes as a runner's stitch. Many athletes also report shoulder tip pain (STP) associated with the ETAP. Although widely known, ETAP remains under analyzed and nether reported in the medical literature. Oftentimes idea of as benign and cocky-limiting, ETAP has been shown to be very detrimental to the functioning of many athletes from novice to elite. This case report of an elite triathlete with ETAP and subsequent review of literature, outlines the various theories near the etiology of ETAP, the epidemiology associated with it, some differentials to consider, and how chiropractic care may benefit those suffering from ETAP.

Résumé

La douleur abdominale passagère liée à l'exercice (DAPE) est mieux connue par les athlètes sous le nom de point du coureur. De nombreux athlètes rapportent également une douleur à la pointe de 50'épaule (DPE) associée à la DAPE. Quoiqu'elle soit bien connue, la DAPE est peu analysée et peu déclarée dans la littérature médicale. On a démontré que la DAPE, souvent considérée bénigne et autolimitative, peut être très nuisible au rendement de bon nombre d'athlètes des catégories novice à élite. Le rapport de cas d'un triathlète de haut niveau avec DAPE et la revue de la littérature ultérieure soulignent les diverses théories concernant l'étiologie de la DAPE, l'épidémiologie qui y est associée, certains différentiels à considérer et comment les soins chiropratiques peuvent profiter aux personnes qui souffrent de DAPE.

Introduction

Exercise-related transient abdominal hurting (ETAP) is more normally known to athletes equally a stitch, sew together in the side, side cramp, side ache and subcostal pain.^{1 , 2} Many athletes also study shoulder tip pain (STP) associated with the ETAP.ⁱ Although widely known, ETAP remains under analyzed and under reported in the medical literature.²

Case study

History

A 20 year old triathlete presented to the clinic complaining of a 1.five to 2 year history of right sided abdominal hurting that merely occurred with training. He has been a triathlete for 4 years and has always been enlightened of some cramping but never this astringent. The onset was unclear but the athlete felt information technology might have been due to a new bike that wasn't set up for him properly and seemed to force him into a more kyphotic posture in the thoracic spine. The cramping was aggravated by his eye charge per unit getting over 170 bpm which occurred oft during "intensity training," the bear on of running, oblique exercises during gym workouts and performing a side bridge exercise. He stated that the hurting would start during the swim portion of the triathlon and worsened with the bike and run. The pain was always localized to the upper correct quadrant of his abdomen in the area immediately inferior to the ribs. He related that the pain would progress to the right diaphragm on occasion but did not mention any related shoulder tip hurting. During an episode, the pain would get-go as a "tightening" and progress to a "abrupt pain." He likewise reported trouble breathing when the pain would get intense. He could push button himself through the pain without the pain getting whatever worse but, on two occasions, was unable to complete races; 1 during the run phase in 2003 and i during the swim stage in 2004. The intensity of the pain would frequently reach a nine on a 10 point scale (10 beingness the worst hurting) with a varied time in onset during training.

Other associated symptoms included tight "hips" and cramping in his right posterior ribs with running. He has had an x-ray and an ultrasound of his abdomen which were read as normal. His previous handling for this injury included acupuncture, ART to his psoas and iliacus, and a core stability program with little success.

The patient was a educatee and he did non report having the intestinal pain with whatever of his normal activities of daily living.

Physical exam

A physical examination revealed bilateral hip tightness peculiarly of the hip flexors, extensors and abductors. Musculus testing revealed inhibition in the psoas bilaterally (right > left), gluteus medius bilaterally (right > left), and the right external rotators of the hip. (Added note by writer: in this case inhibition was used to describe non-painful, non-neurologic weakness of these muscles.) Motion palpation revealed restrictions in the thoracic spine and thoracolumbar junction. In detail, the T9 facet on the right and its corresponding costovertebral joint recreated a milder version of the pain of chief complaint in the belly. Tender points revealed by digital palpation were found in the psoas, rectus femoris, gluteus medius, spinal erectors, latissimus dorsi and iliacus bilaterally, and the right TFL, QL, internal oblique, and transverse abdominus. None of these tender points recreated the pain of the chief complaint.

Diagnosis and treatment

The patient was afterwards diagnosed with exercise-related transient abdominal pain (ETAP) with associated lower kinetic chain myofascial dysfunction as well as thoracic and thoracolumbar joint dysfunction. He was subsequently treated with Art®, spinal manipulative therapy and exercise to affected areas for four treatments over the class of a month. Practice therapy included psoas, rectus femoris and QL stretches, core stability exercises on the stability ball, gait and residual training on a balance axle and running drills stressing proper gait mechanics (eg. walking A's).

The patient was asked to keep a log of activity, training intensity and ETAP intensity over the class of the month. His training intensity remained high while training five–six days per week. His ETAP intensity varied from a low of 2/x to a high of 8/ten (on two training days) and was consistently below 5/10. The patient was extremely happy with the subtract in hurting with treatment (9/ten to five/x on average with a low of two/10) only was unable to keep treatment due to extensive travel in lodge to comply with the program of management.

Epidemiology

Information technology has been reported that "GI symptoms such as nausea, airsickness, belching, bloating, heartburn, chest hurting, GI cramps, side anguish, and diarrhea are experienced past 20–50% of athletes."³ They are receiving more and more attention by athletes, coaches and medical practitioners due to the detrimental impact these symptoms tin have on performance.³ In their study, Peters et al^three constitute that runners experienced more lower GI symptoms than upper (71% versus 36%) while cyclists had both upper (67%) and lower (64%). This was confirmed by the triathletes in their study who experienced more lower (79%) than upper (54%) while running and both upper (52%) and lower (45%) while cycling.³ Side ache was considered to be a part of the lower GI symptoms.

Morton and Callister,^two in a report of 965 athletes in 6 sports constitute that 61% of athletes had experienced ETAP over the period of ane twelvemonth. Broken downward by sport, swimmers reported having had ETAP the most (75%), followed past runners (69%), horseback riding (62%), aerobics (52%), basketball (47%) and cycling (32%). In some other study by Morton, Richards and Callister,⁴ it was found that during a 14 km community walk/run 31% of the participants had experienced ETAP and 42% of those said it negatively affected their performance. ETAP does not seem to affect the athlete during every exercise session. Morton and Callisterⁱⁱ found that 52% of the athletes reported information technology occurred less than x% of the fourth dimension while 82% said it occurred in no more than than 20% of their do sessions.

Although often thought of as mild and beneficial, in those athletes that experienced ETAP, 84% of them reported that ETAP acquired them to reduce their intensity level (72%) or stop the activeness altogether (12%).² These results indicate that over half of the athletes polled felt that ETAP had a deleterious effect on their performance. Our athlete described several incidents where he was forced to tiresome down every bit a effect of ETAP and in a couple of instances had to stop completely.

Shoulder tip pain (STP) has been found to be a component of ETAP for some athletes just not all.² In their survey, Morton and Callister² defined the STP every bit not-injury related that localized to the lateral one/three of the trapezius border extending to the acromion consistent with referred hurting from the diaphragm. They found that 34% of the athletes had non-injury related shoulder hurting but only 47% of those localized information technology to the same part of the trapezius. This constituted 14% of the total respondents. Again broken down by sport, runners experienced the nigh STP at 17%, followed by pond (15%), aerobics (11%), basketball (10%) and cycling (iv%) (horseback riding was not included).² In our case, the athlete did not report any STP associated with his ETAP.

ETAP and STP are also not mutually exclusive. Most oftentimes those with STP had ETAP (xviii%) but there were some athletes that only reported STP (eight%).^{2 , 5}

Location and character

It is a commonly held clinical belief that ETAP occurs mostly on the right side and is a benign cramping sensation relieved after a few seconds of rest but this is not entirely true for every athlete with ETAP.ⁱⁱ

ETAP is well localized in 79% of the cases and in the aforementioned spot in 62%.² The well-nigh common area for ETAP is the right middle 3rd of the abdomen (but adjacent to the umbilicus) in 58% of athletes followed by the left middle 3rd (43%) and umbilical area (21%)(percentages were >100% due to people experiencing ETAP in more than 1 expanse).² ETAP, notwithstanding was experienced to a bottom degree in all areas of the abdomen.² Our athlete consistently reported the location of his ETAP to be in the right upper quadrant of the belly.

Using Melzack and Torgersons 10 pain descriptors, Morton and Callister² found that the pain was described most often as sharp (35%), cramping (27%), stabbing (15%), agonized (nine%) and pulling (6%). In terms of severity, they found that ETAP was near severe at iv.vii +/− 0.ane on a 10 point numerical rating calibration with stabbing being the near severe followed by sharp, aching, cramping, and pulling.²

Those athletes who reported their ETAP to be the most severe experienced ETAP more oft, had more than residual soreness and felt that the pain took longer to resolve.ⁱⁱ

Factors affecting ETAP and STP

Very few studies have looked at the factors that affect ETAP and STP. It has been thought that ETAP is more pronounced in younger athletes and those athletes that are less fit.⁵ In an endeavor to elucidate these and other factors affecting ETAP, Morton and Callister,⁵ in their survey of 965 athletes, asked for subjective data on height, weight, age, and grooming volume and frequency. Their findings are summarized beneath.⁵

• Historic period: Consistent with clinical observation, the prevalence, severity and frequency of ETAP and STP were both significantly decreased with increasing age. Although the severity of the pain on the 10 point numerical scale was found to significantly decrease with age, the descriptors used for the pain awareness were not significantly affected by age. The reason for the changes seen due to age were not easily explained using the electric current theories of the cause of ETAP and STP.

• BMI: The prevalence and frequency of ETAP and STP were non afflicted by BMI although those with a higher BMI had more localized ETAP and reported more severe STP but not ETAP.

• Gender: Few gender differences with respect to ETAP and STP were institute. Men were more likely to report ETAP as "aching" compared to women.

• Training: Training more frequently significantly decreased the frequency of ETAP in those surveyed simply had little upshot on the severity and prevalence. These two measures also seemed unrelated to the number of years in the sport or preparation volume. Morton and Callister⁵ concluded that, contrary to the popular belief that novice athletes who were less fit would feel more severe ETAP and STP, athletes of all levels were just equally susceptible.

Provoking factors

Morton and Callisterⁱⁱ have also surveyed athletes with respect to those factors that may provoke ETAP. Because of its transient nature, many athletes, in an endeavor to explain their symptoms, link certain "things or weather" with their ETAP. The following is a list of the subjective factors that the athletes reported as provoking their ETAP:

• eating (52%) and drinking (38%) – these could exist broken downward further into specific types of food and drink – high carbohydrate content (37%), water (30%), fatty foods (16%), fruit and fruit juices (fifteen%), and dairy products (10%);

• poor fitness level;

• loftier exercise intensity; competition;

• lack of warm-upwardly;

• exercising in cold conditions.

Peters^vi attempted to determine if the osmolality of supplements administered to triathletes during bouts of running and cycling increased their gastrointestinal symptoms. Each athlete completed three trials with different supplementation separated past ane week. The three supplements included a hypertonic (higher osmolarity) high free energy drink of forty mg of carbohydrate in 100 ml of water, a semi-solid supplement mixture of banana, white breadstuff, marmalade, and water and an equal volume of a placebo fluid with flavouring similar to the high free energy drink. Following the ingestion of the supplement prior to each bout of exercise, a hypotonic thirstquencher (iv mg of carbohydrate (orange juice) and 100 ml of h2o) was administered at fifteen minute intervals during each bout. The placebo group received a thirstquencher flavoured placebo in a like time interval. With respect to ETAP (side ache in the report) and the osmolality of the supplement, there was a pregnant difference found between the 1st running bout and the second cycling bout for the high free energy and semi-solid supplements (P < 0.01) as well equally the placebo supplement (P < 0.05). There was also a significant deviation for the loftier free energy supplement and side ache (P < 0.01) between the 1st cycling bout and the 1st running bout. This suggests that hypertonic fluids may be slightly more provoking cistron in ETAP during running compared to cycling just all three supplements did provoke ETAP.^{2 , 6} There was no meaning difference between the 3 supplements and the occurrence of ETAP. Peters,⁶ in his discussion, suggested that the supplements may take been "mildly hypertonic" during the exercise bouts due to the mixing of the hypotonic thirstquencher throughout each trial. This may accept contributed to the insignificant findings.

Plunkett^vii also attempted to decide if osmolality played a role in the development of ETAP. He found during progressive bouts of exercise, hypertonic fluids caused a significantly greater amount of ETAP compared to no fluids and hypotonic fluids. The fluids used in order of increasing osmolarity were no fluids, water, Exceed (a commercial energy drink), Coca-cola, and Duphalac (a solution of the sugar lactulose). This suggests that hypertonic fluids may play a role in ETAP during sustained bouts of exercise.

More enquiry is needed to determine if the osmolality of food or fluids has an influence on ETAP and/or its intensity.

Etiology – proposed theories

The exact etiology of ETAP has yet to be elucidated although in that location are numerous proposed theories.

Diaphragmatic ischemia

One of the traditional causative explanations of ETAP is diaphragmatic ischemia due to the shunting of blood from the respiratory muscles to the gut or to the muscles involved in movement.ⁱⁱ

Origins of this theory are rooted in the referral of the diaphragm to tip of the shoulder, the subjective association of eating and drinking and increasing intensity (increased respiration) with ETAP, and the most common location of ETAP existence the periumbilical/sub-diaphragmatic regions.^{2 , 5 , 7}

This theory is unlikely because of the pain of ETAP being as low as the iliac and hypogastric regions and the depression incidence level of STP (14%) compared to ETAP (61%).^v A study done by Roussos and Macklem^eight refuted the shunting theory in office past showing that during decreased cardiac output, the respiratory muscles may actually deprive the rest of the trunk of blood. This makes sense from a survival standpoint – animate is the near essential component of life. Plunkett^seven reported on another study that showed that following the ingestion of a big repast, there was no change in diaphragmatic movement under fluoroscopy with those runners experiencing ETAP. Although the diaphragm may be involved in ETAP, this suggests that diaphragmatic ischemia was not the cause.

Visceral ligament stress

Another early on competing theory for the cause of ETAP and STP was stress on the visceral ligaments (gastrophrenic, lienophrenic and coronary ligaments) connecting the diaphragm to the abdominal organs.^{2 , seven} Early anecdotal evidence suggested that ETAP may be caused by the vertical jolting in such sports equally camel riding, horseback riding and driving vehicles "off road."^seven Morton and Callister², and Plunkett^vii report that Sinclair was the showtime to propose the theory of visceral ligament stress. Visceral ligament stress could account for STP referral from the diaphragm, the varied location of ETAP in the abdomen which Sinclair felt was due to referred pain from the ligaments themselves, and the subjective increase in ETAP following meals.^{2 , 7} Plunkett^seven also reported a instance of a witting patient who reported ETAP-similar hurting during abdominal surgery when in that location was traction on the mesentery.

Although the above observations lend acceptance to the visceral ligament theory, the fact that intestinal pain is usually along the midline and described as slow and not well localized is in contrast to the hurting of ETAP.² ETAP is usually well localized, all over the abdomen and can be abrupt or stabbing in grapheme.²

Plunkett^seven attempted to test the offset ii theories of ETAP by having athletes assimilate fluid of varying absorbability and utilize various concrete methods in an attempt to increase or decrease the amount of ETAP. Their results, although in a modest sample size, showed little testify for the diaphragmatic ischemia theory. More of their outcomes pointed in the direction of the visceral ligament stress theory although conflicting results yet left some doubts as to this theory'south applicability.

Muscle balk

A considerable number of athletes (27%) describe ETAP as a cramping awarenessⁱⁱ and in plow feel that a muscular cramp may exist the root cause. Although the varied location of ETAP and good localization may be explained by the musculus cramp theory, its ability to explain the cause of STP is not. Muscle cramping is non highly regarded in the literature as a possible theory of ETAP and fifty-fifty its ain cause is not well understood.^two

Morton and Callister^nine recorded surface EMG in the area of pain during an episode of ETAP in 14 symptomatic individuals. There was no change in EMG activeness immediately post exercise following the onset of ETAP compared to immediately after the pain had subsided. Both recordings were taken with the subject semi-reclined and with them property their jiff in order to reduce the activity of the abdominals and diaphragm respectively. They also recorded EMG during specific tests designed to activate the respiratory musculature which was detected at the site of ETAP notwithstanding was not recorded during an episode of ETAP. This suggests that respiratory muscle cramping was not responsible for the pain associated with ETAP.^ix

Morton and Callister¹⁰ compared spirometry results before and later on an episode of ETAP in 14 subjects that developed symptoms during a treadmill exam. They found that there were no significant changes in spirometry values suggesting that the diaphragm is not direct related to the cause of ETAP. This further reinforces that diaphragmatic ischemia and respiratory musculus cramping are not involved in the etiology of ETAP.

Parietal peritoneum irritation

The irritation of the parietal peritoneum is another competing theory of the etiology of ETAP.² The parietal peritoneum consists of the layers of tissue that line the intestinal wall and the pelvic crenel. The visceral peritoneum is the layer of tissue lining the intestinal organs separating them from the parietal peritoneum by a potential space known as the peritoneal cavity. This cavity is filled with a serous fluid to convalesce friction betwixt the two layers.^eleven

In their report in 2000, Morton and Callister^two felt that ETAP may be a form of exertional peritonitis secondary to friction betwixt the parietal and visceral folds. Their argument is summarized below:

• the multi-level innervation of the viscera explaining the varied location of ETAP;

• the innervation of the subdiaphragmatic portion of the parietal peritoneum by the phrenic nerve could, potentially, cause STP;

• the highly localized and sharp pain with irritation of the abdominal part of the parietal peritoneum;

• the distension of the tum with a large meal may increment the friction between the surfaces;

• the friction between the surfaces could be afflicted by the osmotic gradient in the viscera explaining the subjective changes in ETAP with hypertonic food and drink;

• the fact that the parietal peritoneum is sensitive to movement when irritated;

• the modify in awareness in ETAP with increasing intensity of movement which would exist consistent with an increase in the amount of friction.

These points led them to the decision that ETAP was linked to the irritation of the parietal peritoneum.^{1 , 2}

Thoracic facet referral

Morton and Aune¹² reported on a instance of ETAP in an aristocracy 25 year old middle distance runner that experienced increasingly frequent bouts of increasingly severe ETAP following an injury to the thoracic spine. The exact pain of ETAP for this patient was recreated with palpation of the thoracic facet that corresponded to the dermatomal level of innervation to the painful expanse. Following this discovery, they examined 17 other runners to farther investigate this theory. They found that in 47% of the athletes, their exact awareness of ETAP was reproduced with palpation of the thoracic facets from T8 to T12 and in another 35% they reported pain referral toward the site of ETAP. They also reported that an increased thoracic kyphosis is provocative of ETAP.¹² This theory is consequent with the findings of ETAP with jolting activities such as horseback riding, all terrain driving/racing and camel racing. The dermatomal innervation of the abdomen by the diverse levels of the thoracic spine¹¹ may also explain ETAP'due south varied locations and its consistent localization. Thoracic facet referral does not explicate STP yet.

In our case, the athlete reported a like sensation (just less intense) to his ETAP with palpation of his right mid-thoracic spine facet and costovertebral expanse. This suggests that his ETAP in part was associated with some thoracic spine dysfunction.

Psoas major and Quadratus lumborum

The medial arcuate ligament of the diaphragm forms a fascial curvation roofing the psoas major muscle and blending with its fascia.^{11 , 13} The lateral arcuate ligament of the diaphragm has a like attachment with the quadratus lumborum muscle.^{11 , 13} These muscles play an important function in the segmental stabilization of the lumbar spine.^{14 , 15} Information technology is believable that tightness/dysfunction in these muscles could consequence in the subdiaphragmatic pain of ETAP and STP secondary to the attachment to the diaphragm. This could explicate the prevalence of ETAP in those sports that cause vertical jolting (horse back riding, camel racing) and those that require repetitive hip flexion (running, cycling, swimming, aerobics). Information technology also explains the increment in ETAP during intense intervals with these sports because of the increase in the static and dynamic activation of the psoas and quadratus lumborum muscles and the increase in diaphragm activation secondary to increased oxygen demand. It does non, nonetheless, explain the various locations of pain in the abdomen with ETAP.

Our athlete had considerable tightness, dysfunction and inhibition in his psoas and QL bilaterally (right greater than left) which may have contributed to his ETAP.

Differential diagnoses

Eichner¹⁶ outlines several differential diagnoses that demand to exist considered when an athlete presents with symptoms of ETAP. Likewise, because ETAP has a relatively consistent localization and character of pain, a change in location and intensity in an athlete with a previous diagnosis of ETAP must be re-examined and other differentials must be ruled out based on the location of the pain. Although there are many causes of intestinal hurting, the following outlines a few differential diagnoses in which symptoms are increased with exercise including:^sixteen

• upper left quadrant: Splenic enlargement may cause upper left quadrant hurting and is common in mononucleosis. Splenic infarction must be considered in athletes with sickle cell trait when training or competing at distance.

• flank hurting: An athlete with astute, severe flank pain especially with radiations into the groin may exist experiencing renal colic due to kidney stones. If the flank hurting is acute and bilateral, astute renal failure must be considered likewise as rarely diagnosed practise-induced loin pain syndrome.

• upper quadrant pain above the costal margin: Specially in rowers, a stress fracture of the ribs or intercostal muscle strain must be entertained with stabbing pain above the costal margin.

• upper medial quadrant: With midline pain in the upper quadrant, abdominal wall muscle strain may mimic ETAP and must be ruled out.

• lower quadrant: If the hurting presents in the lower quadrant pain, exercise associated abdominal ischemia could be the cause.

Eichner^xvi reminds usa of the sometime aphorism, depending on what role of the world you lot are from, when you lot hear hoof beats you think horses but it may also be zebras. The following include several zebras easily mistaken for classic ETAP:

Chronic constipation

Anderson^{16 , 17} reported the case of a fourteen year old female runner who reported ongoing, well localized, periumbilical pain that was worsening over the period of 4–v months prior to examination. The pain was initially described every bit a deadening ache that progressed to a abrupt hurting when running (rated every bit vi/10) but always resolved within a few minutes of stopping. On presentation, her pain had increased in frequency and severity (at present rated equally 9/10) and was forcing her to stop running. Her physical exam and laboratory studies were inside normal limits. An x-ray showed a moderate amount of stool located diffusely throughout her colon but was within normal limits. On consultation with a gastroenterologist, he suggested the jarring from running may be provoking a clinically silent and relatively mild constipation. The patient was prescribed psyllium and within 10 days her pain with running had resolved. On follow-up 6 months afterward, she had continued to maintain her fibre intake and was still hurting gratuitous with running.

Adhesion of ascending colon to anterior abdominal wall

Lauder and Moses^{sixteen , 18} reported the case of a 28 twelvemonth old elite, male person triathlete with no previous history of abdominal pain who suffered an astute attack of sharp correct-sided abdominal hurting during the run portion of a triathalon. After the first episode, he continued to accept a similar pain during training while running and while swimming to a lesser degree. His hurting continued to be severe during other races and he subsequently underwent further evaluation that revealed adhesions between the ascending colon and the anterior abdominal wall. The adhesions were surgically lysed and the athlete was able to resume training and subsequent races in a pain free country.

Chronic cholecystitis

Dimeo et al^{xvi , nineteen} reported on a 29 year old aristocracy, male, long altitude runner that had had a 12 year complaint of severe, stitching type, upper right quadrant abdominal pain with strenuous, intense grooming and racing. The hurting had worsened a few months prior to presentation and in the prior few weeks had progressed to a similar upper right quadrant hurting following eating fatty meals. Laparoscopic abdominal surgery was performed and revealed congenital adhesions anteriorly betwixt the gallbladder and liver to the abdominal wall and posteriorly between the gall-bladder, transverse colon and liver. The adhesions were sectioned and the gallbladder was removed revealing a chronic cholecystitis on histological examination. No post-operative complications occurred and on 2 year follow-up, he had raced several times with no return of symptoms.

Median Arcuate Ligament Syndrome

Desmond and Roberts²⁰ reported on a instance of ETAP in a 21 year old elite eye distance runner. He reported recurrent upper intestinal discomfort and diarrhea with increased intensity of training. He had had symptoms since he was fifteen years old. He was found to have compression of the celiac artery by the median arcuate ligament. The median arcuate ligament is a tendinous band uniting the medial portion of the two crura of the diaphragm.^eleven His symptoms of diarrhea and ETAP were completely relieved past surgery and he was able to return to competitive running.

Handling

Thoracic mobilization/manipulation

In their case written report, Morton and Aune¹² reported that mobilization of the affected thoracic facet along with mobilizing exercises over a four calendar week menses reduced the hurting of ETAP and immune the patient to return to competitive running.

In a pilot report by Schiller²¹, spinal manipulative therapy of the thoracic spine was found to be more effective than placebo treatment for mechanical thoracic spine pain. This suggests that SMT may be effective in the handling of ETAP if thoracic spine symptoms are nowadays. DeFranca and Levine²² also plant some success with manipulation of the thoracic spine for T4 syndrome.

Our patient was manipulated in the thoracic spine as part of his handling regimen which may have contributed to his reduction in symptoms.

Soft tissue therapy and stretching

Our patient was treated with ART® of his psoas and quadratus lumborum specifically as well every bit other gluteal and hip musculature for a period of 1 calendar month. Follow-upwards stretching of the QL and psoas were prescribed for the patient. Treatment and stretching of the patient'due south psoas and QL may take contributed to his reduction of symptoms.

Dietary modifications

A diet log and food/drink intake schedule during training may reveal whatsoever consistent triggers of ETAP and lead to subsequent dietary alterations in an endeavour to prevent the onset of ETAP. Hypertonic supplements (food or fluid) may produce more ETAP and so hypotonic supplements although more research needs to be done in this expanse.^{six , seven} By monitoring intake during training, athletes with food or fluid triggers may be able to place and avoid these triggers thus avoiding a decrease in operation due to ETAP. It is also suggested that non-symptomatic supplementation during training be maintained during race days.

Our athlete did not study any food or beverage triggers.

Other

In their survey, Morton and Callister² asked how those athletes that suffered from ETAP treated information technology. Their treatments included bending over forward (18%), stretching the affected site (22%), deep breathing (xl%), and pushing on the afflicted area (31%). Deep breathing and bending forward were reported as the most effective by those that that suffered ETAP more severely.² In the study by Plunkett,⁷ three methods of reducing run up were employed including: contraction of the abdominals; modified breathing; and tightened abdominal belt. They establish that stitch was relieved rapidly and significantly with these maneuvers and its intensity was restored within 30–60 seconds of them being stopped.

Our athlete did not study any cocky-treatment methods.

Conclusions

ETAP is a very common condition known to most athletes. Although nearly often thought of as minor annoyance during grooming and competition, Morton and Callister² have shown that it can be astringent enough to cause an athlete to end completely. Its cause at this fourth dimension is unknown only several theories have been put forrad. This suggests that more time should be spent on elucidating its cause and subsequent treatment in an endeavor to reduce its impact on those athletes that suffer from ETAP.

Limitations and directions for future written report

One of the limitations of this example study was the inability of the patient to continue treatment. Information technology is feasible, although unlikely due to connected training, that symptom resolution was due to natural history or other training modifications. With continued treatment longer than ane month, the ETAP intensity may accept returned or resolved completely. An analysis of his swimming, running and cycling biomechanics may have been benign to elucidate grooming errors but was non undertaken.

Future study is needed to determine the underlying cause of ETAP, in particular whether it tin can be explained by one unified theory or if diverse subtypes of ETAP exist. Many injuries are the consequence of a combination of factors including preparation errors, poor biomechanics, muscular imbalance and poor nutrition. To notice the individual cause in a multisport athlete can be like trying to find several needles in the proverbial haystack just finding them could aid further directly handling and prevention strategies.
