The effects of cryotherapy on quadriceps electromyographic activity and isometric strength in patient in the early phases following knee surgery.

Purpose: 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.

Comparison of 6-minute walk test performance between male Active Duty soldiers and servicemembers with and without traumatic lower-limb loss.

The rehabilitation of U.S. military servicemembers (SMs) who have sustained a traumatic loss of one or both lower limbs requires outcome measures that can assess their physical capabilities in comparison with their uninjured colleagues.

Construct validity of Comprehensive High-Level Activity Mobility Predictor (CHAMP) for male servicemembers with traumatic lower-limb loss.

This study examined the convergent construct validity of a new performance-based assessment instrument called the Comprehensive High-Level Activity Mobility Predictor (CHAMP) as a measure of high-level mobility in servicemembers (SMs) with traumatic lower-limb loss (LLL). The study was completed by 118 SMs. Convergent construct validity of the CHAMP was established using the 6-minute walk test (6MWT) as a measure of overall mobility and physical function and the Amputee Mobility Predictor (AMP) as a measure of basic prosthetic mobility.

Association of generalized joint hypermobility with a history of glenohumeral joint instability.

Context: Little is known about the relationship among sex, generalized joint hypermobility, and glenohumeral joint instability.

Objective: To examine the relationship among sex, generalized joint hypermobility scores, and a history of glenohumeral joint instability within a young, physically active cohort and to describe the incidence of generalized joint hypermobility within this population.

Design: Cross-sectional cohort study.

Patellar tendon versus hamstring tendon autografts for anterior cruciate ligament reconstruction: a randomized controlled trial using similar femoral and tibial fixation methods.

Background: Controversy remains over the most appropriate graft for anterior cruciate ligament reconstruction.

Hypothesis: There is no significant difference in outcomes after 4-strand hamstring and patellar tendon autograft anterior cruciate ligament reconstructions using similar fixation techniques.

Study Design: Randomized controlled trial; Level of evidence, 1.

The clinical efficacy of kinesio tape for shoulder pain: a randomized, double-blinded, clinical trial.

Study Design: Prospective, randomized, double-blinded, clinical trial using a repeated-measures design.

Objectives: To determine the short-term clinical efficacy of Kinesio Tape (KT) when applied to college students with shoulder pain, as compared to a sham tape application.

Background: Tape is commonly used as an adjunct for treatment and prevention of musculoskeletal injuries.

Comparison of a lateral hop test versus a forward hop test for functional evaluation of lateral ankle sprains.

The purposes of this study were to determine whether a lateral hop test was a more sensitive functional test over time than a forward hop test in assessing lateral ankle sprains, and whether lateral hop performance can predict a subjective score from an ankle rating scale. At the United States Military Academy, cadets presenting with ankle sprains during an 8-month period were included in this observational study. Patients were asked to perform a lateral hop for distance and a forward hop for distance on both the injured and uninjured lower extremities.

Deep vein thrombosis in an athletic military cadet.

Study Design: Resident's case problem.

Background: A 21-year-old healthy athletic male military cadet with complaint of worsening diffuse left knee pain was evaluated 4 days after onset. The knee pain began 2 hours after completing a long car trip, worsened over the subsequent 3 days, and became almost unbearable during the return trip.
