Athletic Training and Clinical Nutrition Faculty Publications

CONTEXT: A single clinical assessment device that objectively measures scapular motion in each anatomical plane is not currently available. The development of a novel electric goniometer affords the ability to quantify scapular motion in all three anatomical planes.

OBJECTIVE: Investigate the reliability and validity of an electric goniometer to measure scapular motion in each anatomical plane during arm elevation.

DESIGN: Cross-sectional.

SETTING: Laboratory setting.

PATIENTS OR OTHER PARTICIPANTS: Sixty participants (29 females, 31 males) were recruited from the general population.

INTERVENTION(S): An electric goniometer was used to record clinical measurements of scapular position at rest and total arc of motion …

Reliability And Validity Of A Biomechanically Based Analysis Method For The Tennis Serve, Natalie L. Myers, W. Ben Kibler, Leah Lamborn, Belinda J. Smith, Tony English, Cale A. Jacobs, Timothy L. Uhl

Background: An observational tennis serve analysis (OTSA) tool was developed using previously established body positions from three-dimensional kinematic motion analysis studies. These positions, defined as nodes, have been associated with efficient force production and minimal joint loading. However, the tool has yet to be examined scientifically.

Purpose: The primary purpose of this investigation was to determine the inter-observer reliability for each node between two health care professionals (HCPs) that developed the OTSA, and secondarily to investigate the validity of the OTSA.

Methods: Two separate studies were performed to meet these objectives. An inter-observer reliability study preceded the …

A Biomechanically Based Observational Tennis Serve Analysis Method Can Be Used To Assess Serve Mechanics, Natalie Myers

Theses and Dissertations--Rehabilitation Sciences

Traditional sports science motion analysis techniques using three-dimensional (3D) kinematics have demonstrated that proper mechanics enhance serve performance and improper mechanics overload tissues resulting in injury. However 3D analysis is costly, time-consuming, and requires extensive knowledge of biomechanical properties and data analysis. Currently there are no simple, reliable, and valid observational methods for health care providers (HCP) and tennis professionals to evaluate tennis serve mechanics. Researchers investigating observational analyses have determined that superior reliability may be a result of specific operational definitions and the incorporation of educational training sessions on how to perform the analysis.

The first purpose of this …
