Return to Sports Following Shoulder Injury: Clinical Evaluation, Isokinetic, and Functional Testing.

ABSTRACT: The shoulder is commonly injured in overhead sports. This is associated with a high degree of mobility at the expense of stability, sports specific demands, high volume or intensity of practice and competition, biomechanical deficits, and poor technique. Following injury, the return to competition process includes nonsurgical or surgical treatment, comprehensive rehabilitation, and a structured return to sports program. The return to sports continuum is divided into phases which include return to practice of the sport, return to competition at a lower level or with reduced performance, and return to expected performance. Components of the return to sports decision include clinical evaluation of physical and psychological readiness, measurement of muscle strength using isokinetic tests, evaluation of overhead functional tasks, and progression in a supervised interval throwing program. The evidence for the effectiveness of return to sports programs following shoulder injury is limited but evolving and is an area that will merit continued investigation.

Evidence for isokinetic and functional testing in return to sport decisions following ACL surgery.

The rupture and reconstruction of the anterior cruciate ligament (ACL) of the knee are associated with an increased risk of functional instability, a reduction in sports performance, and a higher risk of future additional injuries. Competitive athletes who participate in sports that require pivoting, cutting, and jumping are at particularly high risk for ACL rupture. The return to sport progression continuum after surgery includes sports-specific rehabilitation, evaluation of strength and function, gradual participation in exercise training with progressively challenging activities in the field of play, participation in sports at a lower level, and finally a return to preinjury-level sports competition. This narrative review evaluates the evidence that supports the use of quadriceps and hamstrings isokinetic strength testing and sports-specific functional skills assessments to evaluate progress with rehabilitation after ACL surgery. Strength evaluations, hop tests, agility tests, and the limb symmetry index are described, as well as the associations of quadriceps and hamstrings muscle strength and functional test results with successful return to sports and the risk of ACL graft rupture and contralateral knee injuries. Suggestions for future research directions are presented including the importance of presurgery testing, standardization of test batteries, and comparison of test results with normative data.

Musculoskeletal Conditions in Older Men and Women: An Emergency Room Study.

OBJECTIVE: To study the utilization of emergency room (ER) services for health complaints of the musculoskeletal (MSK) system in older men and women. METHODS: Data from all medical encounters at the ER of a teaching hospital for calendar years 2016-2020 were extracted from an electronic database. MSK encounters were defined as those with ICD 10-CM M and S codes in the primary diagnosis field of the database. Frequency distributions were calculated by year, sex, and age group for MSK and all encounters. The most frequent codes used by sex and age groups were assessed. RESULTS: The number of unique patients with medical encounters at the ER during the five-year period was 94,346. There was a total of 220,153 encounters (median:1 encounter per patient; interquartile range:1-3). A 33.2% reduction in the number of encounters occurred in 2020 compared to 2019. The total number of unique patients in the 60 yr. and older group was 24,412 (25.9% of all unique patients). The total number of encounters in the group 60 yr. and older was 56,294 (25.6% of all encounters). Women accounted for 31,488 (56%) encounters in this age group. A total of 12,744 encounters (22.6%) in older adults involved the MSK system and this proportion decreased with increasing age. The most common MSK conditions included low back pain, pain in joints, and femoral fractures. CONCLUSION: Older adults with MSK health conditions represent a substantial portion of ER patients. Many MSK health conditions could be evaluated and treated in other health care settings.

Musculoskeletal Conditions in the Emergency Room: A Teaching Opportunity for Medical Students and Residents.

OBJECTIVE: Assess the potential value of an emergency room (ER) for the teaching of musculoskeletal (MSK) medicine to medical students and residents in training. METHODS: Data from all encounters to the ER of a teaching hospital for calendar years 2016-2019 were extracted from an electronic database. Encounters with ICD-10-CM M codes (MSK system) and S codes (injury) were selected (MSK encounters). Frequency distributions were calculated by year, sex, and age group for all encounters and MSK encounters. Annual distributions of encounters involving the shoulder, hip, knee, and ankle joints were assessed. RESULTS: The number of unique patients seen during the four-year period was 84,094, and the number of encounters was 187,829 (Median: 1 encounter; interquartile range: 1-2). The mean number of encounters per year was 46,957 (range: 45,311- 48,382). There was no seasonal variation. Most patients were women (45,868; 54.6%) and young (20 29 yr.) adults (15,012; 17.8%), and these groups generated the largest numbers of encounters (women: 108,799; 57.9%; young adults: 35,969; 19.1%). A total of 41,353 encounters (22.0% of all encounters) involved the MSK system. The shoulder, hip, knee, and ankle were involved in 2,768 (1.5%), 1,592 (0.8%), 3,082 (1.6%), and 1,718 (0.9%) encounters, respectively. The most common conditions for each joint were shoulder pain, femoral fracture, knee contusion, and ankle sprain. CONCLUSION: Our findings suggest that ER physicians should have broad knowledge of MSK conditions and injuries. An ER is an excellent location for the teaching of MSK medicine to medical students and residents of other training programs.
