Athy V, Hach S, Anderson H, Mason J. Examining the Peer-Reviewed Published Literature Regarding Low Back Pain in Rowing: A Scoping Review. Int J Sports Phys Ther 2023; 18:55-69. [PMID: 36793564 PMCID: PMC9897042 DOI: 10.26603/001c.67836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 11/30/2022] [Indexed: 02/04/2023] Open
Abstract
Background Low back pain (LBP) is highly prevalent in the rowing population. The body of existing research variously investigates risk factors, prevention, and treatment methods. Purpose The purpose of this scoping review was to explore the breadth and depth of the LBP literature in rowing and to identify areas for future research. Study Design Scoping review. Methods PubMed, Ebsco and ScienceDirect were searched from inception to November 1, 2020. Only published, peer-reviewed, primary, and secondary data pertaining to LBP in rowing were included for this study. Arksey and O'Malley's framework for guided data synthesis was used. Reporting quality of a subsection of the data was assessed using the STROBE tool. Results Following the removal of duplicates and abstract screening, a set of 78 studies were included and divided into the following categories: epidemiology, biomechanics, biopsychosocial, and miscellaneous. The incidence and prevalence of LBP in rowers were well mapped. The biomechanical literature covered a wide range of investigations with limited cohesion. Significant risk factors for LBP in rowers included back pain history and prolonged ergometer use. Conclusion A lack of consistent definitions within the studies caused fragmentation of the literature. There was good evidence for prolonged ergometer use and history of LBP to constitute risk factors and this may assist future LBP preventative action. Methodological issues such as small sample size and barriers to injury reporting increased heterogeneity and decreased data quality. Further exploration is required to determine the mechanism of LBP in rowers through research with larger samples.

The Effects of Increasing Trunk Flexion During Stair Ascent on the Rate and Magnitude of Achilles Tendon Force in Asymptomatic Females. J Appl Biomech 2023; 39:10-14. [PMID: 36513076 DOI: 10.1123/jab.2022-0165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 10/07/2022] [Accepted: 10/20/2022] [Indexed: 12/15/2022]
Abstract
Research indicates that increasing trunk flexion may optimize patellofemoral joint loading. However, this postural change could cause an excessive Achilles tendon force (ATF) and injury risk during movement. This study aimed to examine the effects of increasing trunk flexion during stair ascent on ATF, ankle biomechanics, and vertical ground reaction force in females. Twenty asymptomatic females (age: 23.4 [2.5] y; height: 1.6 [0.8] m; mass: 63.0 [12.2] kg) ascended stairs using their self-selected and flexed trunk postures. Compared with the self-selected trunk condition, decreases were observed for peak ATF (mean differences [MD] = 0.14 N/kg; 95% confidence interval [CI], 0.06 to 0.23; Cohen d = -1.2; P = .003), average rate of ATF development (MD = 0.25 N/kg/s; 95% CI, 0.07 to 0.43; Cohen d = -0.9; P = .010), ankle plantar flexion moment (MD = 0.08 N·m/kg; 95% CI, 0.03 to 0.13; Cohen d = -1.1; P = .005), and vertical ground reaction force (MD = 38.6 N/kg; 95% CI, 20.3 to 56.90; Cohen d = -1.8; P < .001). Increasing trunk flexion did not increase ATF. Instead, this postural change was associated with a decreased ATF rate and magnitude and may benefit individuals with painful Achilles tendinopathy.

Lumbar Intervertebral Disc Degeneration Does Not Affect Muscle Synergy for Rowing Activities. Appl Bionics Biomech 2021; 2021:6651671. [PMID: 33628330 PMCID: PMC7899783 DOI: 10.1155/2021/6651671] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 01/17/2021] [Accepted: 02/03/2021] [Indexed: 11/17/2022] Open
Abstract
Rowers with disc degeneration may have motor control dysfunction during rowing. This study is aimed at clarifying the trunk and lower extremity muscle synergy during rowing and at comparing the muscle synergy between elite rowers with and without lumbar intervertebral disc degeneration. Twelve elite collegiate rowers (with disc degeneration, n = 6; without disc degeneration, n = 6) were included in this study. Midline sagittal images obtained by lumbar T2-weighted magnetic resonance imaging were used to evaluate disc degeneration. Participants with one or more degenerated discs were classified into the disc degeneration group. A 2000 m race trial using a rowing ergometer was conducted. Surface electrodes were attached to the right rectus abdominis, external oblique, internal oblique, latissimus dorsi, multifidus, erector spinae, rectus femoris, and biceps femoris. The activity of the muscles was measured during one stroke immediately after 20% and 80% of the rowing trial. Nonnegative matrix factorization was used to extract the muscle synergies from the electromyographic data. To compare the muscle synergies, a scalar product (SP) evaluating synergy coincidence was calculated, and the muscle synergies were considered identical at SP > 75%. Both groups had only one module in the 20% and 80% time points of the trial. At the 20% time point of the 2000 m rowing trial, the SP of the module was 99.8%. At the 80% time point, the SP of the module was 99.9%. The SP results indicate that, at 20% and 80% time points, both groups had the same module. The module showed a high contribution in all muscles. The activation coefficients indicated that the module was always highly activated throughout the rowing stroke in both groups. The trunk and lower extremity muscles are mobilized through the rowing stroke and maintain coordination during rowing. There was no difference in the muscle synergy between the rowers with and without lumbar intervertebral disc degeneration.

Abstract
OBJECTIVE To determine the association between selected biomechanical variables and risk of patellofemoral pain (PFP) in males and females. DESIGN Prospective cohort. SETTING US Service Academies. PARTICIPANTS Four thousand five hundred forty-three cadets (1727 females and 2816 males). ASSESSMENT OF RISK FACTORS Three-dimensional biomechanics during a jump-landing task, lower-extremity strength, Q-angle, and navicular drop. MAIN OUTCOME MEASURES Cadets were monitored for diagnosis of PFP during their enrollment in a service academy. Three-dimensional hip and knee kinematic data were determined at initial contact (IC) and at 50% of the stance phase of the jump-landing task. Logistic regression analyses were performed for each risk factor variable in males and females (P < 0.05). RESULTS Less than 10 degrees of hip abduction at IC [odds ratio (OR) = 1.86, P = 0.03] and greater than 10 degrees of knee internal rotation at 50% of the stance phase (OR = 1.71, P = 0.02) increased the risk of PFP in females. Greater than 20 degrees of knee flexion at IC (OR = 0.47, P < 0.01) and between 0 and 5 degrees of hip external rotation at 50% of the stance phase (OR = 0.52, P = 0.04) decreased the risk of PFP in males. No other variables were associated with risk of developing PFP (P > 0.05). CONCLUSIONS The results suggest males and females have differing kinematic risk factor profiles for the development of PFP. CLINICAL RELEVANCE To most effectively reduce the risk of developing PFP, the risk factor variables specific to males (decreased knee flexion and increased hip external rotation) and females (decreased hip abduction and increased knee internal rotation) should be addressed in injury prevention programs.

Abstract
AimTo report the epidemiology of injury and illness in elite rowers over eight seasons (two Olympiads).MethodsAll athletes selected to the Australian Rowing Team between 2009 and 2016 were monitored prospectively under surveillance for injury and illness. The incidence and burden of injury and illness were calculated per 1000 athlete days (ADs). The body area, mechanism and type of all injuries were recorded and followed until the resumption of full training. We used interrupted time series analyses to examine the association between fixed and dynamic ergometer testing on rowers’ injury rates. Time lost from illness was also recorded.ResultsAll 153 rowers selected over eight seasons were observed for 48 611 AD. 270 injuries occurred with an incidence of 4.1–6.4 injuries per 1000 AD. Training days lost totalled 4522 (9.2% AD). The most frequent area injured was the lumbar region (84 cases, 1.7% AD) but the greatest burden was from chest wall injuries (64 cases, 2.6% AD.) Overuse injuries (n=224, 83%) were more frequent than acute injuries (n=42, 15%). The most common activity at the time of injury was on-water rowing training (n=191, 68). Female rowers were at 1.4 times the relative risk of chest wall injuries than male rowers; they had half the relative risk of lumbar injuries of male rowers. The implementation of a dynamic ergometers testing policy (Concept II on sliders) was positively associated with a lower incidence and burden of low back injury compared with fixed ergometers (Concept II). Illness accounted for the greatest number of case presentations (128, 32.2% cases, 1.2% AD).ConclusionsChest wall and lumbar injuries caused training time loss. Policy decisions regarding ergometer testing modality were associated with lumbar injury rates. As in many sports, illness burden has been under-recognised in elite Australian rowers.

Abstract
This case presents symptom resolution for a long-distance runner with chronic Achilles tendinopathy (AT), following a partial tear of his Achilles tendon. The patient reported a sudden pain during a morning run, with preserved function. Three hours postinjury, he was reviewed in a musculoskeletal clinic. An ultrasound scan confirmed a partial Achilles tear, associated with significant Doppler activity. His index of AT severity The Victorian Institute of Sports Assessment - Achilles Questionnaire (VISA-A) 4 hours postinjury was markedly higher compared with 2 weeks preinjury, indicating reduced symptom severity. A follow-up scan 4 weeks postinjury showed minimal mid-portion swelling and no signs of the tear. His VISA-A score showed continued symptom improvement. This case represents resolution of tendinopathic symptomatology post partial Achilles tear. While the natural histories of AT and Achilles tears remain unknown, this case may indicate that alongside the known role of loading, inflammation may be a secondary mediator central to the successful resolution of AT pain.

Abstract
This study's objective was to collect items from experienced sports physicians, relating to the presence and severity of overuse wrist injuries in young athletes, for developing a measurement instrument for signals of overuse wrist injury. Seven Dutch elite sports physicians involved in guidance and treatment of young athletes in wrist-loading sports (gymnastics, tennis, judo, field hockey, volleyball and rowing) participated in a focus group. They discussed signals and limitations related to overuse wrist injuries in young athletes. Data were coded and categorised into signals and limitations with subcategories, using an inductive approach. Of the resulting 61 signals and limitations in nineteen (sub)categories, 20 were considered important, forming a comprehensive item set for identifying overuse wrist injury in young athletes. Signals such as pain, "click", crepitations, swelling and limited range of motion were marked useful for early identification of overuse wrist injury. Limitations in movement and performance were considered indicative of severe overuse injury but less relevant for initial injury identification. The focus group provided 17 important signals and 3 important limitations indicative of overuse wrist injury. These provide the basis for a valid measurement instrument for identifying overuse wrist injury in young athletes, with equal emphasis on pain and on other symptoms.

Abstract
Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of anterior knee pain in the elite female athlete can present a challenge to clinicians. Although patellofe-moral pain is the most common diagnosis, other uncommon causes include PVNS and residual scar formation in patients with a history of surgery or trauma. Magnetic resonance imaging (MRI) images are helpful in confirming the diagnosis, however, in a subset of patients, the physician must rely on clinical suspicion and physical exam to make the proper diagnosis. Given the possibility of a false negative MRI images, patients with persistent anterior knee pain with a history of knee surgeries and focal tenderness reproducible on physical exam may benefit from a diagnostic arthroscopy.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) tear rates are known to vary from sport to sport. To the best of our knowledge, the relationship of ACL injury with different sports is not reported earlier. The objective of the present study is to investigate the association of ACL injury with different sports and to document various associated ligamentous, meniscal, and chondral lesions of the knee. MATERIALS AND METHODS Descriptive epidemiological study was carried out in a tertiary care center over a 10-year period. Data were collected of the 638 ACL injured elite sportspersons operated by us. Percentage of ACL injuries and other associated injuries of the knee in different games was calculated. Chi-square test was applied to analyze the relationship between injuries of the specific structures of knee and sports played. p values less than 0.05 were considered to be statistically significant with a confidence interval of 95%. RESULTS Kabaddi and football constituted the highest percentage (61%) of ACL injuries. Associated injuries were 10 posterior cruciate ligament tears, 11 posterolateral corner injuries, three medial collateral ligament tears, 390 meniscal tears (206 medial, 184 lateral), 201 femoral/tibial condylar lesions (128 medial, 40 lateral femoral condyle and 17 medial, 16 lateral tibial condyle), and two common peroneal nerve injuries. Lateral meniscal tears in kabaddi and medial femoral condylar lesions in badminton were significantly higher. CONCLUSIONS Kabaddi resulted in higher number of ACL injuries and other associated injuries to the knee. Further investigation is required to ascertain high-risk factors for such injuries.

Abstract
BACKGROUND A stinger is a type of neurapraxia of the cervical roots or brachial plexus and represents a reversible peripheral nerve injury. The incidence of and major risk factors for stingers among young rugby players remain uninvestigated. PURPOSE To investigate the incidence, symptoms, and intrinsic risk factors for stingers in elite rugby union teams of young players. STUDY DESIGN Descriptive epidemiology study. METHODS A total of 569 male rugby players, including 358 players from 7 high school teams and 211 players from 2 university teams, were investigated using self-administered preseason and postseason questionnaires. RESULTS The prevalence of a history of stingers was 33.9% (95% CI, 30.3-37.9), and 20.9% (119/569) of players experienced at least 1 episode of a stinger during the season (34.2 [95% CI, 26.2-42.1] events per 1000 player-hours of match exposure). The reinjury rate for stingers per season was 37.3% (95% CI, 30.4-44.2). Using the multivariate Poisson regression method, a history of stingers in the previous season and the grade and position of the player were found to be risk factors for stingers during the current season. The mean severity of injury was 2.9 days, with 79.3% (191/241) of the players not losing any time from playing after sustaining a stinger injury and 5.8% (14/241) of the players recovering within more than 14 days. The most frequent symptom was numbness in the unilateral upper extremity, and the most severe symptom was weakness of grasping (mean severity, 6 days). A logistic regression analysis indicated that a history of stingers in the previous season and an injury with more than 3 symptoms, especially motor weakness, were correlated with the severity of injury. CONCLUSION Young rugby players with a history of stingers have a significantly high rate of repeat injuries. Although nearly 80% of the players experienced only minimal (0-1 day) time loss injuries, neurological deficits sometimes last beyond 1 month. A history of stingers was identified to be the strongest risk factor for injuries and for lasting symptoms. This information may be useful for planning the proper treatment for stingers in young rugby players.

Abstract
BACKGROUND The incidence of reinjuries due to glenohumeral instability and the major risk factors for primary anterior shoulder dislocation in youth rugby players have been unclear. PURPOSE The purpose of this study was to investigate the incidence, mechanisms, and intrinsic risk factors of shoulder dislocation in elite high-school rugby union teams during the 2012 season. METHODS A total of 378 male rugby players from 7 high-school teams were investigated by use of self-administered preseason and postseason questionnaires. RESULTS The prevalence of a history of shoulder dislocation was 14.8%, and there were 21 events of primary shoulder dislocation of the 74 overall shoulder injuries that were sustained during the season (3.2 events per 1000 player-hours of match exposure). During the season, 54.3% of the shoulders with at least one episode of shoulder dislocation had reinjury. This study also indicated that the persistence of glenohumeral instability might affect the player's self-assessed condition, regardless of the incidence during the current season. By a multivariate logistic regression method, a history of shoulder dislocation on the opposite side before the season was found to be a risk factor for contralateral primary shoulder dislocation (odds ratio, 3.56; 95% confidence interval, 1.27-9.97; P = .02). CONCLUSIONS High-school rugby players with a history of shoulder dislocation are not playing at full capacity and also have a significant rate of reinjury as well as a high risk of dislocating the other shoulder. These findings may be helpful in deciding on the proper treatment of primary anterior shoulder dislocation in young rugby players.

Abstract
BACKGROUND Therapeutic ultrasound is one of several rehabilitation interventions suggested for the management of pain due to patellofemoral knee pain syndrome. OBJECTIVES To assess the effectiveness and side effects of ultrasound therapy for treating patellofemoral knee pain syndrome. SEARCH METHODS We searched the Cochrane Musculoskeletal Review Group register, Cochrane Field of Physical and Related Therapies register, Cochrane Controlled Trials Register, MEDLINE, EMBASE, HealthSTAR, Sports Discus, CINAHL,and PEDro databases (to December 2000) according to the sensitive search strategy for RCTs designed for the Cochrane Collaboration. The search was complemented with handsearching of the reference lists. Key experts in the area were contacted for any further articles. SELECTION CRITERIA All randomized controlled trials (RCTs), controlled clinical trials (CCTs), case-control and cohort studies comparing therapeutic ultrasound against placebo or another active intervention in people with patellofemoral pain syndrome were selected according to an a priori protocol. DATA COLLECTION AND ANALYSIS Two reviewers determined the studies to be included based on a priori inclusion criteria. Data were independently extracted by the same two reviewers and checked by a third reviewer (BS) using a previously developed form. The same two reviewers independently assessed the methodological quality of the RCTs and CCTs using a validated scale. The data analysis was performed using Peto odds ratios. MAIN RESULTS The search retrieved 85 articles. Of the eight that were potentially relevant, only one RCT, including 53 participants with patellofemoral pain syndrome, was identified for this review. All participants received an exercise program as concurrent therapy. Ultrasound combined with ice massage contrast (n of 13), where n equals the number of participants, was not statistically different from ice massage alone (n = 16) in terms of participant-rated pain relief or quadriceps and hamstring strengthening. In the ultrasound and ice massage group, 46% (6 of 13) reported improved pain relief compared to 31% (4 of 13) in the ice massage alone group. This difference of 15% does not meet international standards for clinically important improvements in osteoarthritis, which is 20%. Side effects were not reported. AUTHORS' CONCLUSIONS Ultrasound therapy was not shown to have a clinically important effect on pain relief for people with patellofemoral pain syndrome. These conclusions are limited by the poor reporting of the therapeutic application of the ultrasound and low methodological quality of the one trial included. No conclusions can be drawn concerning the use, or non-use, of ultrasound for treating patellofemoral pain syndrome. More well-designed studies are needed.

Abstract
Context: Patellofemoral pain syndrome (PFPS) is a common orthopaedic condition for which operative and nonoperative treatments have been used. Therapeutic modalities have been recommended for the treatment of patients with PFPS—including cold, ultrasound, phonophoresis, iontophoresis, neuromuscular electrical stimulation, electrical stimulation for pain control, electromyographic biofeedback, and laser. Objective: To determine the effectiveness of therapeutic modalities for the treatment of patients with PFPS. Data Sources: In May and August 2010, Medline was searched using the following databases: PubMed, CINAHL, Web of Science Citation Index, Science Direct, ProQuest Nursing & Allied Health, and Your Journals@OVID. Study Selection: Selected studies were randomized controlled trials that used a therapeutic modality to treat patients with PFPS. The review included articles with all outcome measures relevant for the PFPS patient: knee extension and flexion strength (isokinetic and isometric), patellofemoral pain assessment during activities of daily life, functional tests (eg, squats), Kujala patellofemoral score, and electromyographic recording from knee flexors and extensors and quadriceps femoris cross-sectional areas. Data Extraction: Authors conducted independent quality appraisals of studies using the PEDro Scale and a system designed for analysis of studies on interventions for patellofemoral pain. Results: Twelve studies met criteria: 1 on the effects of cold and ultrasound together, ice alone, iontophoresis, and phonophoresis; 3, neuromuscular electrical stimulation; 4, electromyographic biofeedback; 3, electrical stimulation for control of pain; and 1, laser. Discussion: Most studies were of low to moderate quality. Some reported that therapeutic modalities, when combined with other treatments, may be of some benefit for pain management or other symptoms. There was no consistent evidence of any beneficial effect when a therapeutic modality was used alone. Studies did not consistently provide added benefit to conventional physical therapy in the treatment of PFPS. Conclusions: None of the therapeutic modalities reviewed has sound scientific justification for the treatment of PFPS when used alone.

Abstract
BACKGROUND Chronic Achilles tendinosis is a common musculoskeletal disorder often refractory to conservative management. Our study aimed to assess the safety and efficacy of the use of autologous skin-derived collagen-producing cells in the treatment of refractory Achilles tendinosis. METHODS We conducted a randomized, double-blind study on forty Achilles tendons in thirty-two patients (eight with bilateral involvement) who had a clinical and radiographic diagnosis of Achilles tendinosis. The patients ranged from twenty-two to sixty-seven years old and had a mean age of 45.2 years. The patients with unilateral involvement were randomized into the treatment group (twelve patients) and control group (twelve patients). The eight patients with bilateral involvement were individually randomized into treatment and control groups, with eight Achilles tendons in each group. Achilles tendons in the treatment group were injected under ultrasound guidance with laboratory-expanded, skin-derived fibroblasts suspended in autologous plasma. The control group received ultrasound-guided injection of a local anesthetic and physiotherapy. The Victorian Institute of Sport Assessment (VISA) questionnaire and visual analog scale (VAS) scores were used as the main outcome measures for both groups. RESULTS Significant differences in the mean VISA and VAS scores were detected between the treatment and the control groups for the patients with unilateral involvement at six months (p < 0.001 for both). With use of the Mann-Whitney U Test, significant differences in the VISA score were observed at the second visit and at the three-month and six-month visits (p = 0.02, p = 0.007, and p < 0.001 respectively). The VAS scores also showed significant differences at the second visit and at the six-month evaluation (p = 0.014 and p < 0.001, respectively). The eight patients with bilateral involvement were analyzed separately; with the number of patients studied, no significant differences in the VISA or VAS scores were observed between the treatment group and the control group. CONCLUSIONS These preliminary short-term results demonstrate that the injection of skin-derived fibroblasts for the treatment of Achilles tendinosis is safe. However, larger studies with a longer duration of follow-up are required to determine the long-term effectiveness before wider clinical application is considered.

Abstract
BACKGROUND Junior rowers have competed internationally for over 4 decades, and there are no epidemiological data available on traumatic and overuse injury in this population. OBJECTIVE To define the types of musculoskeletal problems present in international elite-level junior rowers and to determine whether gender, physical stature, rowing discipline, and training programs affect the incidence of reported injuries. STUDY DESIGN Descriptive epidemiology study. METHODS Injury data were obtained from a total of 398 rowers (42% female, 58% male) who completed a 4-page questionnaire on injury incidence while participating at the Junior World Rowing Championships in Beijing, People's Republic of China, in August 2007. RESULTS Overall, 290 (73.8%) reported injuries involved overuse, and 103 (26.2%) were related to a single traumatic event. Female rowers were injured more frequently than male rowers (110.2 vs 90.5 injuries per 100 rowers). In both genders, the most common injury site was the low back followed by the knee and the forearm/wrist. The severity of reported injuries was incidental in 65.1%, minor in 21.4%, moderate in 10.4%, and major in 3.1% of cases. The rowers with traumatic injuries had less rowing experience than the uninjured rowers (median [C] +/- interquartile range [Q] = 3 +/- 3 years vs 4 +/- 3 years; P = .043, Mann-Whitney test). Sweep rowers who changed rowing side during the current season had significantly more acute-onset low back injuries (P = .012, chi(2) test) than those who did not change rowing side during the same period. The incidence of traumatic injuries was significantly lower in rowers who regularly performed more than 10 minutes of posttraining stretching (P = .030, chi2) test). Athletes who ran more than once a week had more overuse knee injuries than those who ran once or less per week (P = .033, chi2 test). CONCLUSION Elite junior rowers attending the World Rowing Championships reported predominantly overuse injuries of low severity during the current rowing season. Low back injuries were the most frequent complaint of elite-level junior rowers.

Abstract
OBJECTIVE The aim of this systematic review is to provide an easily accessible, clear summary of the best available evidence for nonoperative treatment of midportion Achilles tendinopathy. DATA SOURCES MEDLINE, CINAHL, and Embase through April 2007. Search terms: achilles tendon or tendo achilles or triceps surae or tendoachilles or tendo-achilles or achilles AND tendinopathy or tendinosis or tendonitis or tenosynovitis. STUDY SELECTION Of 707 abstracts reviewed, 16 randomized trials met our inclusion criteria. DATA EXTRACTION Data extracted from each paper included: patient demographics (age and sex), duration of symptoms, method of diagnosis, treatments, cohort size, length of follow-up, pain-related outcome data, and secondary outcome data. DATA SYNTHESIS The primary outcome measurement was change in numeric pain score. Focal tenderness, tendon thickness, and validated outcome scores were used secondarily. Eccentric exercises were noted to be equivalent to extracorporeal shockwave therapy (1 study) and superior to wait-and-see treatment (2 trials), traditional concentric exercise (2 of 3 trials), and night splints (1 study). Extracorporeal shockwave therapy was shown to be superior to a wait-and-see method in 1 study but not superior to placebo in another. Sclerosing injections were shown to be superior to placebo in 1 study, but local steroid treatment was beneficial in 2 of 3 studies. Injection of deproteinized hemodialysate and topical glyceryl nitrate application were beneficial in 1 trial each. CONCLUSIONS Eccentric exercises have the most evidence of effectiveness in treatment of midportion Achilles tendinopathy. More investigation is needed into the utility of extracorporeal shockwave therapy, local corticosteroid treatments, injections of sclerosing agents or deproteinized hemodialysate, and topical glyceryl nitrate application.

Abstract
OBJECTIVE First, to document the injuries sustained during the 2004 Olympic Games in a sample of patients visiting the physiotherapy department of the Olympic Village polyclinic. Second, to provide information and data about the physiotherapy services for planning future Olympics and other mass gatherings. DESIGN Observational study. SETTING Olympic Village polyclinic. PARTICIPANTS 457 patients aged 15-72 years visited the physiotherapy department from 30 July through 30 August. RESULTS The department's workload was at a peak during the last 15 days of the Olympic Games (periods B and C). The most common injuries were overuse injuries (47.3%). The most common pathology for physiotherapy attendance was myofascial pain/muscle spasm (32.5%), followed by tendinopathy (19.2%) and ligament sprain (18.7%). The most prevalent site of injury was the thigh (21%), followed by the knee (14.1%) and the lumbar spine (13.5%). Most injuries had symptoms of <7 days' duration. The geographical region with the greatest demand for physiotherapy services was Africa (40.6%). Most patients were athletes (74.8%), although team officials accounted for a considerable number (14%). CONCLUSIONS The smallest national teams--especially those from developing countries--were more likely to take advantage of services, probably because the larger teams had their own medical and physiotherapy staff. The characteristics of patients, their sustained injuries and the subsequent treatment varied by the accreditation status of the patients. The physiotherapy department's workload was dependent on the Olympic Games schedule.

Abstract
This article systematically reviews epidemiological studies on sports injury from 1977 to 2005 in which ankle injury was included. A total of 227 studies reporting injury pattern in 70 sports from 38 countries were included. A total of 201,600 patients were included, with 32,509 ankle injuries. Ankle injury information was available from 14,098 patients, with 11 847 ankle sprains. Results show that the ankle was the most common injured body site in 24 of 70 included sports, especially in aeroball, wall climbing, indoor volleyball, mountaineering, netball and field events in track and field. Ankle sprain was the major ankle injury in 33 of 43 sports, especially in Australian football, field hockey, handball, orienteering, scooter and squash. In sports injuries throughout the countries studied, the ankle was the second most common injured body site after the knee, and ankle sprain was the most common type of ankle injury. The incidence of ankle injury and ankle sprain was high in court games and team sports, such as rugby, soccer, volleyball, handball and basketball. This systematic review provides a summary of the epidemiology of ankle injury in sports.

Abstract
Shin splints, an exercise-induced form of lower leg pain, is a common complaint among athletes. Considered an overuse injury that compromises the dense and tough fascial attachments of the tibialis posterior and/or tibialis anterior muscles from the tibia, it responds well to a multiphase treatment plan that incorporates plyometric strengthening and conditioning exercises. Plyometrics may be safely introduced as early as the third or functional phase of recovery. A progressive plyometric program that emphasizes a gradual development of eccentric stress loading to the musculoskeletal components of the deep posterior and anterior muscle compartments of the lower leg is described.

Abstract
PURPOSE To review the published and unpublished evidence regarding risk factors associated with shin splints, assess the effectiveness of prevention strategies, and offer evidence-based recommendations to coaches, athletes, and researchers. METHODS We searched electronic data bases without language restriction, identified citations from reference sections of research papers retrieved, contacted experts in the field, and searched the Cochrane Collaboration. Of the 199 citations identified, we emphasized results of the four reports that compared methods to prevent shin splints. We assessed the methodologic quality of these reports by using a standardized instrument. RESULTS The use of shock-absorbent insoles, foam heel pads, heel cord stretching, alternative footwear, as well as graduated running programs among military recruits have undergone assessment in controlled trials. There is no strong support for any of these interventions, and each of the four controlled trials is limited methodologically. Median quality scores in these four studies ranged from 29 to 47, and serious flaws in study design, control of bias, and statistical methods were identified. CONCLUSION Our review yielded little objective evidence to support widespread use of any existing interventions to prevent shin splints. The most encouraging evidence for effective prevention of shin splints involves the use of shock-absorbing insoles. However, serious flaws in study design and implementation constrain the work in this field thus far. A rigorously implemented research program is critically needed to address this common sports medicine problem.

Abstract
Although PFS will continue to be a therapeutic challenge, the prognosis for most female athletes is good, especially if they are motivated and compliant with their treatment program. Particularly in women, care should be taken to avoid placing too much emphasis on biomechanical variants that may not be clinically significant or correctable because such findings can reinforce a feeling that "nothing can be done." In many cases, muscle dysfunction and repetitive loading of the patellofemoral joint rather than fixed biomechanical factors contribute to the development of PFS. Nonetheless, the importance of a detailed biomechanical assessment on physical examination must not be neglected, particularly in athletes who are not improving with conservative treatment and who may become surgical candidates. A practical initial treatment program for most athletes with nontraumatic PFS begins with relative rest, quadriceps strengthening, and stretching of tight myotendinous units. The introduction of NSAIDs, orthoses, taping, knee sleeves, and more specific rehabilitative exercises should be an individualized decision based on physical findings, past treatment results, and athletic expectations. Surgical referral should be considered in cases of PFS or patellar instability refractory to prolonged maximal nonoperative treatment.

Abstract
Studies on the incidence of soccer injuries have produced a variety of sometimes conflicting results. This may be explained by differences in the definition of soccer injury and the methods of data collection being used, and by selection mechanisms in the study populations. The incidence of injuries, therefore, depends on the population being studied. High risk groups exist with respect to age, gender and level of competition. Competition produces a higher risk of injury than practice, even when corrections for exposure time are made. The range of results of studies concerning different aspects of the severity of injuries may also be well explained by differences in the definition of injury, research methodology and selection with respect to age, gender, level of play and sociocultural background. In countries where soccer is very popular, the healthcare and social security systems are taxed considerably. On the other hand, soccer injuries appear to be no more serious than injuries resulting from other sports activities. A general conclusion is that the epidemiological information of the sport medical aspects of soccer injuries is inconsistent and far from complete. More research is needed to identify high risk groups and independent predictor variables of injury within those subgroups. Preferably, such studies should include uniform definitions of injury and should be based on sound epidemiological methodological principles.

Abstract
To assess the value of promoting health through exercise, we review what is known about the medical and medical care resource costs and benefits of exercise. Literature searches were undertaken to derive estimates of the relative risk, in individuals who exercise regularly compared with those who do not, of each of the major disease groups for which there is good evidence that the disease can be ameliorated by exercise (coronary heart disease, stroke, diabetes, hip fracture, and mental illness). These relative risks were used to estimate the incidence of hospital admissions and mortality, and associated healthcare costs, which could be prevented if the whole population exercised. Literature on the incidence and costs of exercise-related morbidity and mortality was also reviewed to derive estimates of both the costs to health and also the healthcare resource implications of exercise in total population. Indirect costs and benefits, and also quality-of-life effects associated with exercise were not included in this assessment. The results show that in younger adults (ages 15 to 44 years) the average annual medical care costs per person that might be incurred as a result of full participation in sport and exercise (approximately 30 pounds British sterling) exceed the costs that might be avoided by the disease-prevention effects of exercise ( less than 5 pounds British sterling per person). However, in older adults ( greater than or equal to 45) the estimated costs avoided ( greater than 30 pounds British sterling per person) greatly outweigh the costs that would be incurred ( less than 10 pounds British sterling). There was little evidence that exercise leads to deferred health or health service resource benefits. We conclude that with regard to health and medical care costs, there are strong economic arguments in favour of exercise in adults aged greater than or equal to 45 but not in younger adults. Estimates derived from the international scientific literature and routine UK data sources may have limited direct application in the healthcare systems of other countries. Nevertheless, the result that exercise costs exceed the benefits in younger adults but vice versa in older people is likely to be generally true. Indeed, a similar result has been found in a study of a Dutch population.

Abstract
Athletes often suffer from recurrent or chronic overuse symptoms of the lower extremities. During the office visit it is essential to analyse the patient's shoes, gait cycle, lower extremities and, especially, the talocrural, subtalar and more distal joints of the ankle and foot. The basic (clinical) biomechanical analysis can be supplemented by radiographs, treadmill and video analysis and mirror table (podoscope) examinations. Ideally, successful pain relief by correction of the observed abnormality with an orthotic device completes the diagnostic procedure, especially if symptoms return soon after the removal of the device. In treatment custom-made, expensive orthotics should not be prescribed for overuse symptoms without an obvious malalignment, for asymptomatic athletes with a malalignment, or for symptoms in which the causal relationship between the biomechanical abnormality and symptoms is difficult to see. Strict indications for prescription of orthotics and close cooperation between the attending physician, physical therapist and orthotist are prerequisites for obtaining good, long-lasting results.

Abstract
A retrospective study is presented of 83 athletes with tendo Achillis pain (TAP) treated conservatively over a 12-year period from 1976 to 1988. Local steroid injections did not contribute to an earlier return to sport, though many individuals were improved symptomatically. Local steroids were not found to have a deleterious effect on outcome. Steroids were used most frequently in the chronic cases that presented late and had been treated previously: this group had most recurrences and surgical intervention. One case of Achilles rupture (3%) occurred in the group treated with steroids. Early presentation for treatment led to an earlier return to sport and avoidance of recurrences. Recurrences were most frequent in athletes with bilateral Achilles tendinopathy. The tendo Achillis lesion may range from peritendinitis through a mixed lesion of the tendon and paratenon, to complete rupture. The management depends upon accurate diagnosis, its chronicity and the age and aspirations of the patient. Steroids are safe to use and further prospective trials should note presentation time and disease staging accurately.

Abstract
This study investigated the relationship between exposure time and ankle sprains in soccer. Forty-one teams (639 players) from four male senior soccer divisions at different levels of skill (divisions I-VI) were followed prospectively for 1 year. The exposure to soccer and the number of injuries per player were higher in higher divisions, but the injury incidence, percentage of ankle injuries and incidence of ankle injuries were the same at different levels of skill. Of all injuries 17 to 20% were ankle sprains and the incidence varied between 1.7 to 2.0 ankle injuries per 1,000 hours of exposure. Since players with previous ankle problems run an increased risk of reinjury we suggest that these players receive preventive advice.

Abstract
Previous reports relating to sports injuries treated at hospital Accident and Emergency departments (A&E) or Sports Injury Clinics (SIC) indicate differences between the groups. This study compared directly the sports injuries treated during overlapping time periods at an A&E department (n = 2490) and a SIC (n = 340) set within the same geographical area. The two populations were found to differ significantly in age, sport, injury and injury site. Hospital patients tended to be younger, with an acute injury to the upper body or head which occurred during participation in sports where contact is likely. SIC patients tended to be older, with chronic or overuse injuries to the back or lower limb. It was found that there are significant differences between the sports injuries treated at the sports injury clinic and the hospital casualty department. It is concluded that demand is clearly shown for both types of treatment site when both are available in the same geographical area.

Abstract
Pathological alterations in chronic Achilles paratenonitis were studied histologically and using immunofluorescence techniques for fibronectin and fibrinogen in tissue samples obtained operatively from 11 athletes with this complaint and from 4 male cadavers serving as controls. The average duration of the paratenonitis was 20.4 months. The paratendineal fatty areolar tissue was clearly thickened and edematous, showing widespread fat necrosis and considerable connective tissue proliferation. The blood vessels were often obliterated and degenerated. Fibronectin and fibrinogen were commonly found in the proliferating connective tissue areas and in the vascular walls. Exudates rich in fibrinogen and fibronectin were seen in the inflamed paratendineal tissues, but not in the controls. The results indicate that increased vascular permeability and fibrin formation still persist in chronic Achilles paratenonitis and that marked obliterative and degenerative alterations of the blood vessels are frequent. The presence of fibronectin and fibrinogen points to an immature nature of scar tissue in chronic paratenonitis.

Abstract
A 30-month prospective follow-up study of children's overuse injuries at an outpatient sports clinic was carried out to determine the number, profile, and specific features of these injuries compared with those of young adults. During this period 74 athletically active boys (less than or equal to 15 years), 83 girls, 255 men (21-30 years), and 77 women visited the station because of an overuse sports injury of the musculoskeletal system. About one-third of the patients of each group did not seek medical help until more than 6 months after the onset of the symptoms. The injuries most commonly affected the lower extremities, with the knee joint involved in about one third of patients. In girls and women, the lower back (13%) was significantly more frequently affected than in boys and men (6%) (p less than 0.01). Thirty two percent of all boys' overuse problems were classified as exercise-induced growth disorders and osteochondritic pains (apophysitides, etc.), but in girls only 13% had a similar basis. The most common diagnosis among boys was Osgood-Schlatter's disease (13 patients, 18%); in girls it was nonspecific synovitis of the knee (9, 16%).

Abstract
In an 8-year retrospective study, 631 injuries due to the racquet sports of squash (59%), tennis (21%) and badminton (20%) were seen in a sports injury clinic, males predominating (58 to 66%). The proportion of squash injuries was higher than expected and probably relates to higher physical stress and risk of contact in this sport. Also they occurred mainly in persons over 25 years (59%) i.e. the reverse for sport in general. Acute traumatic injuries were seen especially in squash players, a majority affecting the knee, lumbar region, muscles and ankle. Tennis injuries differed most with lateral epicondylitis, patello-femoral pain and lumbar disc prolapse being relatively common. The badminton injury pattern overlapped the others. Lower limb injuries predominated in all three. Detailed assessment of 106 cases showed many to be new, infrequent, social players. Poor warm-up was a common factor in new and established players. The importance of these findings is discussed.

Abstract
Soccer injuries which were seen at the King Fahd University Hospital over a period of 12 months were analyzed. The majority of the patients were under 20 years of age. Two-thirds of the injuries involved soft tissue, while those to the bone and joint comprised one-third. The lower extremity was involved in 59%. Sixteen percent of the injuries were considered severe enough to require inpatient treatment. We feel the high incidence of injuries can be reduced by better guidance and coaching at school and other training levels. At present, these patients are seen in the emergency room of our hospital and subsequently in the orthopaedic and fracture clinics. A specialized sports injury clinic staffed with medical and paramedical personnel with special interest in sports medicine would enable early and effective treatment returning athletes to play without undue delay.

Abstract
A one-year prospective follow-up study of all patients visiting Tampere Research Station of Sports Medicine (TRSSM) was carried out in order to determine the specific features of women's sports injuries compared to those of men. During this period 334 women (31%) and 745 men (69%) visited the station. Women were significantly younger than men and the ten most usual sports events causing the injury differed from those of men. In women acute dislocations, contusions, and fractures were significantly less common in men, while women had more frequent stress-related sports injuries. In both sexes the most common sites of trouble were knee, ankle, and lower back, but in women as opposed to men, the metatarsal area, the toes, and the sole were among the ten most usual sites of the injury. Fourteen women (4%) and 49 men (6%) required operative treatment of the injury. The knee was the most common site of operation in both sexes, in women significantly more frequently than in men.

Abstract
At the Tampere Research Station of Sports Medicine (TRSSM) a continuous coding system of patient visits was started on March 1, 1985. The registration form contained 25 variables including all essential information about the patient's identification, sports, time of and reason for the visit, physician, examinations, diagnosis, treatment, and possible further measures. To classify and number the diagnosis, a specific classification of sports injuries and diseases was drawn up. The data were stored and analyzed using a DEC-2060 computer at the University of Tampere. During 6 months a total of 814 visits were recorded. The three most common sports were soccer, long-distance running, and orienteering. Competitive athletes totalled 337 (62%); 43 of these were top-ranking athletes. The most common reasons for visits were problems of the knee (266 visits, 33%), ankle (80, 10%), and low back (71, 9%). Knee sprains accounted for 10% of all visits. Problems related to the musculoskeletal system were the reason for 751 (92%) of all visits. Operative treatment was needed by 49 patients (6%). The continuous coding system of patient visits at an outpatient sports clinic showed great advantages as a basic data bank for scientific research, annual statistics, and patient identification and filing. The system described has been adopted as part of the daily routine at the TRSSM.

Abstract
About one third of all sports injuries admitted to outpatient sports clinics concern knees. The incidence of different knee disorders in an outpatient sports clinic material and a review of the literature concerning the wide and problematic area of knee exertion injuries in athletes is presented. Exertion injury is defined as non-traumatic pain syndrome in the musculoskeletal system, including typical stress injuries and pain syndromes associated with physical activity but also has other important aetiological factors. 2762 athletes were admitted to the Turku Sports Medical Research Unit's outpatient sports clinic from 1976 to 1983 and 886 (32%) of them, 697 male and 189 female athletes, had suffered knee disorders. Football (soccer) [20.8%], long-distance running (13.1%), volleyball (11.6%), orienteering (7.6%) and ice-hockey (7.2%) had the highest incidence and the most common knee disorders were patellar apicitis (20.4%), Osgood-Schlatter's disease (10.1%), patellar chondropathy (10.0%), ligamentous sprains (9.0%) and meniscus tears (6.9%). The mean age of all athletes with knee disorders was 20.8 years. On an average each complaint caused 2.16 appointments. Careful evaluation of malalignments predisposing the athlete to exertion injury is necessary in the treatment of knee disorders and to avoid the recurrence of the exertion injury due to some biomechanical reason. The authors emphasise the importance of careful clinical examination. Although our review does not include detailed information about injuries originating in a single trauma, it is important to pick up the cases of ligamentous tears early so they can be appropriately repaired. Diagnostic and operative arthroscopy adds a new method in avoiding diagnostic errors and in shortening the postoperative rehabilitation.

Abstract
The present investigation reports 138 consecutive patients injured in sports, who needed treatment as in-patients in a one year period. More injuries were sustained in soccer than in other sports. The lower extremity was the site of most injuries, fractures and dislocations being the most common type of injury. At follow-up 50% of the patients complained of discomfort. The average stay in hospital after a sports injury requiring hospital care was 6 days. In 52% of the patients the duration of sports incapacity was at least six months and in seven per cent the sports incapacity after the sustained injury was permanent.

Abstract
Stress fractures of the lower ribs related to sports are rare. Fractures of the ribs related to rowing sports have not been reported. We have documented seven cases of stress fractures of the lower ribs in female athletes; four were elite rowers and three were engaged in tennis, golf, and gymnastics. Each athlete was initially seen and treated elsewhere for muscular strain. All athletes presented with pain in the posterolateral thorax in and around the scapula. The time from onset of symptoms to diagnosis ranged from 2 to 6 months. Bone scans were used to document the fractures when roentgenograms were equivocal. Each athlete responded to a 4 to 8 week period of rest or training modification. Biomechanical analysis of the forces across the ribs demonstrates that these fractures tend to occur along the posterolateral segment where the bending stresses on the rib are greatest. The predominant muscle forces are generated by the forced couple of scapular retraction and protraction acting through the serratus anterior. We postulate that inadequate strength and resistance training background in women is the cause for the apparent increased susceptibility of women to these skeletal injuries.

Abstract
The present investigation analyses 2493 patients with a sports injury treated in a casualty department during a one-year period. Of the patients 73% were men, the age of the patients averaging 26 years and the mean follow-up time was 24 months. Soccer and indoor ball games caused 24% and 23% of the injuries respectively, these being followed by injuries in ice hockey in 14%. Track and field injuries scored low with 2% out of all injuries. Injuries to the lower extremity predominated. At follow-up, ligamentous injuries of the lower extremity were the major cause of discomfort. Further, in the group of patients with persistent discomfort 36% had suffered a fracture or a dislocation, 13% a contusion and 10% a wound. The mean period of sports incapacity after a sustained injury was 3 weeks. In track and field events the injury seldom disturbed training for more than one week, but in soccer, indoor ball games, skiing and skating the mean sports incapacity period varied between 6 and 3 weeks. Out of the total injured, 2% had to give up their sports activity completely. An injury of the lower extremity demanded on average 4 weeks' rest, an injury of the upper extremity and the trunk 2 weeks and injuries of the head and neck one week's rest. According to the present investigation sports injuries were in the majority of cases of a relatively benign nature and sick leave from work seldom exceeded 2 weeks.
