Landing Technique Affects Knee Loading And Position During Athletic Tasks, Nelson Cortes, Steven Morrison, Bonnie L. Van Lunen, James A. Onate

Rehabilitation Sciences Faculty Publications

Anterior cruciate ligament (ACL) injuries have been reported to occur with the ankle in a dorsiflexed position at initial contact. Few studies have attempted to quantify the biomechanical parameters related with such landing patterns during athletic tasks.

Objectives- The purpose of this study was to evaluate the effects that two landing techniques have in lower extremity biomechanics while performing two tasks.

Design- Single-group repeated measures design.

Methods- Twenty female soccer athletes from a Division 1 institution performed two landing techniques (forefoot and rearfoot) during two unanticipated tasks (sidestep cutting and pivot). Repeated measures analyses of variance were conducted to assess …

Upper Extremity Strength Characteristics In Female Recreational Tennis Players With And Without Lateral Epicondylalgia, Ann M. Lucado, Morey J. Kolber, M. Samuel Cheng, John L. Echternach Sr.

Rehabilitation Sciences Faculty Publications

STUDY DESIGN: Descriptive, cross-sectional.

OBJECTIVES: To compare static strength characteristics of the upper extremity musculature in female recreational tennis players with lateral epicondylalgia to those of nonsymptomatic tennis players and a control group of women who did not play tennis.

BACKGROUND: There is a paucity of research describing the relationship between lateral epicondylalgia and strength characteristics of the upper extremity musculature, despite the functional relationship between the shoulder, elbow, and wrist.

METHODS: Sixty-three women were recruited into 3 groups (n = 21 per group): symptomatic tennis players (SIP) with lateral epicondylalgia, nonsymptomatic tennis players, and controls. Data collection was performed …
