Shoulder pain is a very common musculoskeletal complaint, and individuals with shoulder pain comprise a significant percentage of patients seeking medical attention. Lifetime prevalence of shoulder pain has been reported to range from 7% to 36% of the population.11,13 Rotator cuff pathology and subacromial impingement are among the most common diagnoses made in the shoulder region.

To determine the effects of cryotherapy on quadriceps electromyographic (EMG) activity and isometric strength in early postoperative knee surgery patients. Methods: Twenty-two volunteers with recent knee surgeries were included. EMG readings of the vastus medialis (VM), rectus femoris (RF), and vastus lateralis (VL) from the surgical leg were collected during a maximal voluntary quadriceps setting (QS) activity. Maximum isometric knee extension force measurements were also recorded. Subjects were randomly assigned to receive an ice bag or a sham room-temperature bag to the front of their postsurgical knee for 20 min. After treatment, the subjects repeated the above mentioned maximum QS and isometric knee extension force measurements. The subjects returned 24 h later to conduct the same test protocol but received the treatment (ice or sham) not applied during their first test session. Results: A 38% increase in VM EMG activity during QS and a 30% increase in maximum isometric knee extension strength were found after cryotherapy treatment. No significant differences were found in RF or VL EMG activity during QS after cryotherapy. No significant differences were found in any measurements after the sham treatment. Conclusion: Clinicians should consider applying ice to knee joints prior to exercise for patients following knee surgery with inhibited quadriceps.

Helical CT is a reliable and fast method to obtain vital information and to improve management planning in severely injured patients. It reduces the number of conventional x-ray examinations. In certain cases, additional x-rays of extremity fractures may be required.

was developed in an effort to consistently predict injury among military personnel. Current injury prediction tools have not consistently predicted injury in this population. The MRST is comprised of the weight bearing forward lunge, modified deep squat, closed kinetic chain upper extremity stability test (CKCUEST), forward step down with eyes closed, stationary tuck jump, unilateral wall sit hold, and subjective, individual perceived level of risk for injury. The Feagin hop and self-reported history of injury were also included in this study protocol. The Feagin hop was a functional test used consistently by the orthopedic department located at the testing site as well as used in a recent study aimed at defining a return to duty screen; self-reported history of injury has been identified as a potential predictor of injury.Purpose: To examine whether MRST scores, as a composite as individual components, were predictive of a United States Military Academy Preparatory School (USMAPS) student athlete sustaining a future musculoskeletal injury. Study Design: Prospective Cohort StudyMethods: MRST scores were collected for 141 student athletes (mean age 18.63 ±1.31) at USMAPS. The injury surveillance period was nine months. Students participated in regularly occurring military specific training and various sports. Mean scores were compared between injured and uninjured groups; binary logistic regression model was also completed. Results:Seventy students sustained an injury. The top activities resulting in injury included football (36%) and basketball (11%) with injuries predominantly located in the lower extremity including the knee (24%), hip (15%), and ankle (14%). Composite MRST scores were not statistically different between injured (12.58 ± 2.16) and uninjured (13 ± 2.27) groups. There was an association between those with a personal concern for future injury and actual injury (p=.04). There was an association between those reporting a prior injury in the preceding 12 months and those incurring an injury at USMAPS (p=.04). Conclusion:The MRST composite scores were not predictive of injury in this population. Previous injury and personal concern for injury were significant injury predictors. Level of Evidence: 2a

The MRST shows potential as a tool for identifying service members at higher risk for sustaining a musculoskeletal injury. Further research is needed to assess the validity, reliability, and responsiveness of this novel screening tool.

In HRCT reports multiple different, often synonymous, German and English terms are used. The variety of terms impede understanding and acceptance of HRCT. Purpose of this paper is to present a scheme, which is based on the anatomic landmarks (secondary lobule), and the density of pathologic changes, as well as a glossary from the German HRCT-literature, including suitable terms, definitions, synonyms and English terms. Low attenuation changes include emphysemas, air-filled cavities (bullae, cysts, cavitations, honeycombing) and bronchial dilatation, changes with increased density consist of diffuse (ground glass opacity, consolidation) and focal processes (reticular and nodular densities). Reticular densities are categorised in thickened interlobular septae and translobular lines with differentiation of a reticular pattern and curvilinear lines. Nodular processes are categorised according to size, density, morphology, localisation and distribution. Parenchymal distortion and destruction indicate the severity of these processes. Certain patterns are indicative for possible differential diagnoses, and a recommendation for further procedures is given.
