Sonographically guided posterior subtalar joint injections: anatomic study and validation of 3 approaches.

Objective: To describe and validate 3 different approaches to perform sonographically guided posterior subtalar joint (PSTJ) injections.

Design: Sonographically guided procedures performed on cadaveric specimens.

Setting: Procedural skills lab at a tertiary medical facility.

Sonographically guided carpal tunnel injections: the ulnar approach.

Objective: The purpose of this report is to describe a new sonographically guided technique for carpal tunnel injections using an ulnar approach.

Methods: Previously published sonographically guided techniques for carpal tunnel injections were reviewed. Described approaches were noted to be technically challenging because of the need to perform long-axis imaging of the carpal tunnel, short-axis (out-of-plane) imaging of the needle, or both.

Effect of environmental temperature on shock absorption properties of running shoes.

Objective: To determine the effect of temperature changes on the shock attenuation of 4 running shoe shock absorption systems.

Design: Prospective.

Setting: Motion analysis laboratory.

Rhomboid muscle electromyography activity during 3 different manual muscle tests.

Objective: To determine which of 3 previously published rhomboid manual muscle tests (MMTs) elicits the maximal rhomboid electromyographic activity in an asymptomatic population.

Design: Criterion standard.

Setting: Motion analysis laboratory at tertiary care medical center.

Effects of functional knee bracing on muscle-firing patterns about the chronic anterior cruciate ligament-deficient knee.

Objective: To examine the effects of functional knee bracing on the muscle-firing patterns about the chronic anterior cruciate ligament (ACL)-deficient knee in successful brace users.

Design: Cross-sectional comparative clinical trial.

Setting: Motion analysis laboratory.

Tug of war: introduction to the sport and an epidemiological injury study among elite pullers.

The objective of this study was to describe injury patterns among elite tug of war athletes, using a survey method. The setting was the World Tug of War (TOW) Championships in 1998. All 990 male and female athletes asked to participate.

Predictors of injury in ice hockey players. A multivariate, multidisciplinary approach.

Eighty-six male high school ice hockey players participated in this prospective study to determine both the incidence of injury in high school ice hockey and the influence of physical, situational, and psychosocial factors. Physical factors included height, weight, vision, previous injuries, musculoskeletal abnormalities, and injuries present at the time of screening evaluations. Situational factors examined were level of participation, playing time, player position, and games versus practices.

An eccentric- and concentric-strength profile of shoulder external and internal rotator muscles in professional baseball pitchers.

The purpose of this study was to establish a data base on the isokinetic eccentric muscular performance characteristics of external and internal rotator muscles in the shoulders of professional baseball pitchers. Concentric data are also included and compared with previously published concentric studies. Twenty-five professional baseball pitchers were evaluated with a Kin-Com isokinetic dynamometer.

Injuries in Junior A ice hockey. A three-year prospective study.

This 3-year prospective cohort observational analysis of elite amateur hockey players ranging in age from 17 to 20 years on a United States Hockey League team describes ice hockey injuries using a strict definition of injury, standardized reporting strategies, and diagnosis by a team physician. One hundred forty-two injuries were recorded for an on-ice injury rate of 9.4 per 1000 player hours.
