Overuse syndromes among endoscopists.

A survey of 400 gastroenterological endoscopists was carried out to determine what kinds of overuse syndromes they suffer from as a result of doing endoscopic procedures. The response rate was 72%. Thumb pain, hand pain, elbow pain, low back pain, and possibly shoulder pain all appear to be caused by endoscopy to at least some extent. Physicians who perform the most procedures tend to have the highest risk of developing such problems. Age, sex, practice setting, and hobbies did not seem to have an impact on the overuse conditions identified. These conditions are most likely due to the equipment and technique of endoscopy. Further study is needed to determine the anatomic lesions causing the various pain states, so that they can be treated or prevented.

[Possibilities of sonography in patellar apex syndrome].

23 Patients suffering from jumper's knee were examined by sonography. Using ultrasound imaging, we demonstrated pathologic changes in the tendon. Reproducible documentation of the patella tendon was proved by using three specimens. In a control group of 110 normal objects normative values for the size and structure of the tendon were documented. We present a classification using ultrasound patterns. With this classification the diagnosis becomes objective and reproducible. The physician can decide which conservative therapy is appropriate to this state of the disease, the surgeon gets information for the operation, and the success of the therapy can be documented.

Exercise-induced muscle damage.

Muscular overuse is associated with structural damage of the contractile elements and reflected in delayed onset muscle soreness (DOMS). Mechanical stress is supposed to be the major contributing factor for inducing muscle damage. The initial damage is followed by an inflammatory response and eventually by regeneration. Calcium is assumed to play an important role in triggering the inflammatory changes. Biopsy data in man indicate that the inflammatory changes in humans do not parallel the soreness ratings, leaving the delayed onset of muscle soreness unexplained. It is a well known phenomenon that one bout of eccentric exercise has a long lasting protective effect against damage induced by a second bout of exercise. Experimental evidence suggests that this adaptation can partly be attributed to an increase in connective tissue. Plasma CK activity has widely been used as a marker for the amount of muscle damage. It has been shown that gender differences in exercise-induced CK release are caused by sex hormones dependent differences in sarcolemmal permeability. Plasma CK activity does not necessarily reflect the amount of structural damage.

Soreness in lower extremities and back is reduced by use of shock absorbing heel inserts.

Soccer referees participating in large soccer tournaments may develop overuse injuries. In this study the effect of shock absorbing heel inserts in the incidence of soreness was investigated. Forty-eight referees were randomly selected to wear shock absorbing heel inserts (SAH) in the 5 day-tournament, while 43 referees were the control group. A daily questionnaire inquiring about complaints from the locomotive system was completed for each referee and in case of any soreness they were examined by doctors to document and classify the anatomical site. Calf, thigh, back, achilles tendon and knee were the most common localizations of overuse symptoms. The incidence of soreness in achilles tendon, calf and back were significantly reduced by the use of (SAH) inserts.

Topical indomethacin in overuse injuries in athletes. A randomized double-blind study comparing Elmetacin with oral indomethacin and placebo.

In this double-blind trial in 70 athletes with superficial overuse injuries, the effect of topically and systemically administered indomethacin was compared with a placebo control. The treatment period was 2 weeks and blindness was secured by the double-dummy technique. The basic data of the patients showed no significant differences on entry to the study. The majority of cases were acute or subacute, the mean duration of symptoms being 7.4 weeks. The results showed a marked therapeutic effect after 3-7 days of treatment and statistically significant differences between the topical formulation and the placebo were reached in the parameters patients assessment of improvement and pain in connection with daily activity within the first week of treatment. However, during the second week the statistical significances were lost. Only in the topically treated patients local adverse reactions were observed. In the oral indomethacin group all reactions were systemic, GI- and CNS-complaints being predominant. The results on efficacy as well as adverse reactions favour the use of topical indomethacin in superficial overuse injuries in athletes.

Long- or short-acting anesthetic with corticosteroid in local injections of overuse injuries? A prospective, randomized, double-blind study.

A prospective, randomized, double-blind study of 56 patients presenting with an overuse sports injury was undertaken in order to compare the effect of a long-acting anesthetic (bupivacaine) with a short-acting anesthetic (lidocaine) in local corticosteroid injections. At presentation, patients were either administered a periarticular injection of 2 ml of methyl prednisolone acetate with bupivacaine (MPA-B) (40 mgs per ml + 5 mgs per ml) or 2 ml of MPA with lidocaine (MPA-L) (40 mgs per ml + 10 mgs per ml). No other treatment was given. Results indicated that pain inhibition was better in the MPA-B group during the first six hours after the injection, obviously because of the longer half-life of bupivacaine. In later evaluations no differences could be observed: in both groups pain disappeared partly or completely in two-thirds of the patients and full recovery to sports was possible in half of them. Long-acting bupivacaine is recommended as an anesthetic substance in local steroid injections of musculoskeletal overuse injuries.

Results of the surgical treatment of the medial tibial syndrome in athletes.

The medial tibial syndrome (chronic compartment syndrome) is the most common specific overuse injury among athletes in Finland, and it is especially a problem in endurance sports, long-distance running, and jogging. Conservative treatment is usually successful, but if it fails, fasciotomy of the deep posterior compartment is observed to be beneficial. In the years 1975-1984, we performed fasciotomy in 34 patients, of whom 14 had a bilateral operation. Thirty-one patients were active in sports, 22 were long-distance runners and joggers. The operations of 15 patients (22 legs) were performed under local anesthesia as an outpatient procedure. The follow-up results in general were good. In 21 patients (78%) of those 27 who could be followed up, the final result was excellent or good, in 4 (15%) fair, and only in 2 (7%) poor. Fasciotomy is a simple operation and can be performed as an outpatient procedure under local anesthesia. For bilateral symptoms, we recommend two different procedures with a time interval of about 2 weeks to avoid the postoperative hematoma and difficulties in mobilization often seen, when operated simultaneously.

Stress fracture of the rib in an elite oarsman.

This paper documents an unusual case of a stress fracture of the ninth rib in an elite oarsman. A 25-year-old male presented with a 3-day history of right-sided chest pain aggravated by deep inspiration and movements simulating rowing. The athlete was treated initially as having a soft tissue injury; however, a technetium-99 bone scan confirmed the diagnosis. Routine radiographs of the ribs were negative. The pain and symptoms were confined to the anatomical area of the fracture along the anterolateral portion of the rib where the serratus anterior muscle originates. An analysis of the stroke mechanics involved in rowing implicated the serratus anterior muscle as being a major contributor to the repetitive stress that resulted in the injury. The primary etiological factor was errors in the training program. The athlete responded to simple conservative measures and was able to return to competitive rowing in 1 month's time.

Epidemiology of injuries in Danish championship tennis.

During the outdoor tennis season of 1984 a prospective injury registration was done in 104 randomly chosen elite tennis players, of whom 86% could be followed. We found 46 injuries: an incidence of 2.3 injuries/player/1000 tennis hours. Men were more frequently injured than women. The prevalence was 0.3 injury/player. Upper extremity injuries were most frequent - 45.7% (21/46). Shoulder injuries were the single most frequent injury - 17% (8/46). The pathophysiology was overuse in 67% (28/42), strains in 14% (6/42), sprains in 17% (7/42), fractures in 2% (1/42), and blisters in 5% (2/42). Players using conventional rackets had more injuries to the upper extremity compared with players using mid/oversized rackets, though the difference was nonsignificant. The importance of impact forces from the tennis stroke in the mechanism of upper extremity injuries is discussed.

Effects of repeated exhaustive exercise on myocardial subcellular membrane structures.

The effects of a single vs repeated bouts of exhaustive exercise on myocardial integrity were evaluated in the rodent. Rats were randomly divided into three groups: a sedentary control, single swim-to-exhaustion, and seven consecutive daily swims-to-exhaustion groups (n = 5 in each group). Overall morphology was evaluated histologically and sarcolemmal (SL), sarcotubular (ST), and mitochondrial (MITO) membranes were examined ultrastructurally using transmission electron microscopy. Neither single nor repeated bouts of exhaustive exercise produced myocardial hypoxia, as assessed by MITO morphology. However, increased interstitial space as well as significant swelling (P less than 0.01) was observed in ST from both 1- and 7-day exhausted animals. These findings were not observed at all in control myocardium. Higher magnification (x 45,000) in some instances revealed whole disruption of sarcotubular membranes in myocardium from swim-exhausted animals. The incidence of membrane disruption was higher (P less than 0.01) in 7-day vs 1-day swim-exhausted groups and not observed at all in control rats. Although in no instance did we observe disruption of SL membranes, their convoluted nature in myocardium from both exercised groups indicated exhaustion-induced fluid and/or ionic shifts within the left ventricle. These findings provide a structural basis for the reduction in myocardial sarcoplasmic reticulum and MITO Ca++ uptake previously observed following repeated bouts of exhaustive exercise.

Exercise-induced signs of muscle overuse in children.

Signs of overuse after intense muscular exertion are well described in adults, while little research has been conducted in children. The aim of the study was to investigate some indirect markers of muscle damage in 13 years old boys following two different protocols of one-leg stepping exercise to exhaustion. This stepping exercise was performed by two experimental groups with different contributions of concentric and eccentric contractions in a 1:1 vs 1:2 ratio of timing. Subjective soreness perception and maximum voluntary isometric force of the knee extensor muscles were measured immediately prior to and immediately following the exercise, and at 1, 3, 24, 48, 72, 96 hours post exercise. Metabolic markers of exercise stress were taken at similar time intervals and included plasma glutathione concentrations as a marker for oxidative stress, circulating leukocyte numbers, and plasma creatine kinase (CK) activity. All parameters studied demonstrated a higher level of muscular exertion, with more evident signs of overuse in the group with the more eccentric contribution. Complete recovery was achieved between 72 and 96 hours after exertion. However, in this group of boys, the CK activity did not show the typical adult-like increase. Therefore the wide use of CK as an indicator of intense muscle exertion was not supported in this group of children. It can be concluded that children, like adults, experience similar degrees of muscle disturbances following intense exercise and that they may recover more quickly from such exercise.

Injury and training characteristics of male Elite, Development Squad, and Club triathletes.

Links between overuse injury prevalence in triathletes training for 1.5km, 40km, 10km triathlon and both intrinsic and extrinsic factors were assessed in 12 Elite, 17 Development and 87 male Club triathletes by a five year retrospective questionnaire. Elite, Development and Club triathletes differed in training mileage, duration and number of workouts but not in overall injury prevalence, distribution, and severity. Overuse injury occurred in 75.0% of male Elite Squad, 75.0% of Development Squad and 56.3% of Club athletes with 1.9-2.9 sites affected. The most common injuries - the achilles tendon (10.3-17.9%), lower back (15.8-17.9%) and knee (14.2-21.9% of injuries) - were also among the most severe. Running injuries accounted for more of the total number of injuries than cycling injuries in Elite (62.1 % vs 34.5%, p<0.05), Development (64.3% vs 25.0%, p<0.05) and Club triathletes (58.7% vs 15.9%, p<0.05). The number of running injuries sustained correlated with triathlon training distance, cycling distance (p<0.03), swimming distance (p<0.01), number of triathlon workouts (p<0.03) and number of running sessions (p<0.03) within one weeks race training. The number of overuse injuries sustained during cycling correlated with time spent running and cycling.

Acute and chronic over-exertion: do depressed immune responses provide useful markers?

There are ethical objections to inducing cumulative muscle damage and associated decrements of performance deliberately in a healthy athlete. Available data on acute and chronic over-exertion thus include the changes of immune response observed following a single bout of exhausting exercise, sequential observations made on top-level competitors as they approach peak training periods, and longitudinal laboratory studies of heavy (but not necessarily damaging) bouts of training. In all three of these situations, subclinical muscle damage initiates an acute inflammatory response, with a resulting deterioration in physical performance. Although much smaller in degree and shorter in duration, the associated changes in immune function are similar to those seen in sepsis. There have been major advances in immunological technique over the past decade, and significant changes in a number of elements of the immune response can be identified in athletes during periods of heavy training. The most promising immunological marker of excessive training seems a decrease in salivary IgA concentration. However, no single change occurs with sufficient consistency to identify the individual competitor who is at risk of overtraining. Mechanisms can be conceived that convert a sequence of excessive training bouts into an acute and then a chronic inflammatory process, but the syndrome of overtraining has a complex overlay of biological and psychological influences. It remains more easily detected by decreases in physical performance and alterations in mood state than by changes in immune function.

Injuries in male soccer players: team risk analysis.

Selection may be responsible for different characteristics of subgroups (teams) of soccer players resulting in different risks of injury and different injury patterns. In the present study injury rates of teams were analysed with respect to the factors age and level of play. In two Dutch non-professional soccer clubs 477 male players, active in teams of different age groups and at different levels of play, were prospectively followed during the second half of the 1986/1987 competitive season. Teams in the 17/18 years age group showed the highest incidence of injury per 1000 players hours in games. At a high level of play teams have a significantly (p < 0.01) higher risk of injury than teams at a low level of play. This difference is noticed within every age group with exception of the 15/16 years age group. At a high level of play teams of senior players have significantly (p < 0.005) more prevalent injuries than teams of junior players. Senior players, active at a high level of play, have significantly (p < 0.05) more overuse injuries than senior players of a low level of play. At a high level of play significantly (p < 0.05) more upper leg injuries are reported. In the total population of soccer players relatively more sprains are located in the ankle joint and relatively more strains are located on the upper leg. It is concluded that prevention of soccer injuries primarily should be aimed at teams and their environment and not at the individual soccer player.

An epidemiological analysis of overuse injuries among recreational cyclists.

Two-hundred and ninety-four male and 224 female randomly selected recreational cyclists responded to a mail questionnaire. Significant differences were observed between male and female cyclists' training characteristics. Overall, 85% of the cyclists reported one or more overuse injury, with 36% requiring medical treatment. The most common anatomical sites for overuse injury/complaints reported by the male and female cyclists combined were the neck (48.8%), followed by the knees (41.7%), groin/buttocks (36.1%), hands (31.1%), and back (30.3%). For the male cyclists, effect upon back and groin/buttocks overuse injuries/complaints were miles/week, lower number of gears, and less years of cycling. For female cyclists, training characteristics which had the most significant effect upon groin/buttocks overuse injury/complaints were more non-competitive events/year and less stretching before cycling. The odds of female cyclists developing neck and shoulder overuse injury/complaints were 1.5 and 2.0 times more, respectively than their male counterparts.
