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 …

Temporal Neuromuscular Alterations Of The Quadriceps After Unilateral Anterior Cruciate Ligament Reconstruction, Conrad M. Gabler

Theses and Dissertations--Rehabilitation Sciences

Objective: The primary aim of this research was to examine the temporal pattern of neuromuscular quadriceps deficits in both the involved and uninvolved limbs of patients assigned to the control group after anterior cruciate ligament reconstruction (ACLr), by assessing quadriceps strength, voluntary activation, and corticomotor excitability prior to surgery (baseline), three months after ACLr, and six months after ACLr. A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported function at six …

Prospective Assessment Of Return To Pre-Injured Levels Of Activity, Aaron D. Sciascia

Theses and Dissertations--Rehabilitation Sciences

Determining return to pre-injured levels of play following athletic injury can be challenging. The current practice of making decisions following rehabilitation as to whether or not a patient has returned to pre-injured levels of activity is potentially inaccurate because initial assessments of perceived physical capability are performed at a time of relative dysfunction or are based on patient recall. Since there is no true baseline of perceived and physical function prior to injury it is difficult to determine if an athlete has return to baseline or is simply better than they were at the time of injury. Therefore, it is …
