ABSTRACT
CONTEXT: Achilles tendon (AT) rupture in athletes is increasing in incidence and accounts for one of the most devastating sports injuries because of the threat to alter or end a career. Despite the magnitude of this injury, reliable risk assessment has not been clearly defined, and prevention strategies have been limited. The purpose of this review is to identify potential intrinsic and extrinsic risk factors for AT rupture in aerial and ground athletes stated in the current literature. EVIDENCE ACQUISITION: A MEDLINE search was conducted on AT rupture, or "injury" and "risk factors" and "athletes" from 1980 to 2011. Emphasis was placed on epidemiology, etiology, and review articles focusing on the risk for lower extremity injury in runners and gymnasts. Thirty articles were reviewed, and 22 were included in this assessment. RESULTS: Aerial and ground athletes share many intrinsic risk factors for AT rupture, including overuse and degeneration of the tendon as well as anatomical variations that mechanically put an athlete at risk. Older athletes, athletes atypical in size for their sport, high tensile loads, leg dominance, and fatigue also may increase risk. Aerial athletes tend to have more extrinsic factors that play a role in this injury due to the varying landing surfaces from heights and technical maneuvers performed at various skill levels. CONCLUSION: Risk assessment for AT rupture in aerial and ground athletes is multivariable and difficult in terms of developing prevention strategies. Quantitative measures of individual risk factors may help identify major contributors to injury.
ABSTRACT
OBJECTIVE: Kinesio taping (KT) is used to prevent and treat musculoskeletal injuries. This systematic review examines the evidence for the effectiveness of KT in improving patient outcomes following musculoskeletal injury. MATERIALS AND METHODS: A literature search (October 2011) was performed using PubMed, CINAHL, Scopus, SportsDiscus, and Cochrane databases. The literature search employed the keywords "kinesio tap*" or "kinesiotap*" or "athletic tap*" and "performance" or "function" or "strength" or "activity" or "pain" or "muscle" and "athlet*" or "sport*." These searches yielded a total of 727 articles, which were reviewed thoroughly to identify suitable articles. RESULTS: Six studies met our criteria and were included in this systematic review. Two of these studies examined musculoskeletal injuries in the lower extremity and reported that the use of KT did not affect outcome measures. Two studies examined musculoskeletal injuries involving the spine. Treatment with KT significantly improved pain levels and range of motion in patients with acute whiplash-associated disorders of the cervical spine both immediately and 24 hours after injury; however, the long-term results did not differ between the 2 groups. Subjects with chronic low back pain treated with KT and exercise, KT alone, or exercise alone experienced significant improvement in short-term pain, while the exercise-only group also showed significantly less long-term disability. Two studies examined musculoskeletal injuries in the shoulder. The first of these found insufficient evidence to indicate that KT decreases pain and disability in young patients with shoulder impingement/tendinitis, while the second suggested that KT may provide short-term pain relief for patients with shoulder impingement. This systematic review found insufficient evidence to support the use of KT following musculoskeletal injury, although a perceived benefit cannot be discounted. There are few high-quality studies examining the use of KT following musculoskeletal injury.
