Humeral Retroversion, Range Of Motion, And Strength Adaptations In Tennis Players, Daniel Hannah Aug 2019

Humeral Retroversion, Range Of Motion, And Strength Adaptations In Tennis Players, Daniel Hannah

Electronic Theses and Dissertations

Purpose: This study aimed to develop an understanding of humeral retroversion (HRV) asymmetries in tennis players and its impact on physical and performance characteristics of the shoulder.Participants: Healthy tennis players were categorized into 3 groups: younger juniors (n=11, age=14.5±0.5 years), older juniors (n=12, age=17.1±0.9 years), and collegiate (n=16, age=19.6±1.2 years). Methods: HRV, internal rotation (IR), and external rotation (ER), total arc of motion (TAM), HRV-corrected IR (HRVcIR), and HRV-corrected ER (HRVcER) were measured and calculated bilaterally using a digital inclinometer and ultrasonography. Bilateral differences (Δ) were calculated (dominant minus nondominant) for HRV and ROM variables. Isometric ER:IR strength ratios …


The Effect Of Functional Movement Control On Patient-Reported Outcomes In Individuals With Non-Arthritic Hip Pain, Ryan Mcgovern May 2019

The Effect Of Functional Movement Control On Patient-Reported Outcomes In Individuals With Non-Arthritic Hip Pain, Ryan Mcgovern

Electronic Theses and Dissertations

Purpose: Both the single leg squat test and step-down test assess for deficiencies relating to the hip and surrounding musculoskeletal structures and could be useful in the evaluation of functional movement control for individuals with non-arthritic hip pain. The purpose of this study is to determine if individuals with non-arthritic hip pain that improve functional movement control during the single leg squat test and step-down test have better patient-reported outcomes than those that do not improve, following the implementation of a rehabilitation intervention and a standardized home-exercise program.

Subjects: Forty-six individuals (31 females; 15 males) with a mean age of …
