In-Season Functional Shoulder Training For High School Baseball Pitchers, Jason Brumitt, Erik Meira, Greg Davidson

Faculty Publications - College of Physical Therapy

The overhead throwing motion is used in numerous sports including track, football, and baseball. Among these sports, the baseball pitch is unique in the demands placed upon the shoulder. The forces created in the shoulder can potentially lead to pathology affecting the athlete's career. To enhance performance and decrease the risk of injury, it is important that the athlete participate in a year-round periodized program. Inappropriate or deficient training combined with the stress that the shoulder experiences during a season can lead to strains, impingement, tendon or labral tears, and instabilities.

Associations Of Knee Angles, Moments And Function Among Subjects That Are Healthy And Anterior Cruciate Ligament Deficient (Acld) During Straight Ahead And Crossover Cutting Activities, Jeff Houck, H. John Yack

Faculty Publications - College of Physical Therapy

The objective of this study was to compare knee angles and moments of healthy subjects (n/20) and subjects that were anterior cruciate ligament deficient (ACLD) (n/16) during stepping and crossover cutting activities. Subjects that were ACLD were separated into high (n/7) and low (n/9) functioning groups based on knee functioning ratings. Knee angles and moments were estimated using three dimensional motion tracking and force plate data. The results suggest that knee angle and moment data were associated with level of functioning of ACLD subjects. Primarily knee frontal and transverse plane moments distinguished the stepping and crossover cut activities. Only some …

Self-Reported Giving-Way Episode During A Stepping-Down Task: Case Report Of A Subject With An Acl-Deficient Knee, Jeff Houck, Amy Lerner, David Gushue, H. John Yack

Faculty Publications - College of Physical Therapy

Study Design: Case report.

Objective: To describe the knee kinematics and moments of a giving-way trial of a subject with an anterior-cruciate-ligament– (ACL) deficient knee relative to his non–giving-way trials and to healthy subjects during a step-down task.

Background: Episodes of giving way are believed to damage joint structures, therefore treatments aim to prevent giving-way episodes, yet few studies document giving-way events.

Methods: The giving-way trial experienced by a 32-year-old male subject with ACL deficiency during a step-down task was compared to his non–giving-way trials (n = 5) and data from healthy subjects (n = 20). Position data collected at …

Neuromuscular electrical stimulation (NMES) has been used to treat a variety of extremity problems in head-injured patients. Specifically, NMES has been used to gain motor control, reduce joint contractures, and reduce muscle hypertonicity.1 Such uses rely on intact peripheral nerve excitability to generate the desired muscular response. This article will present some clinically relevant methods of maximizing the effectiveness of NMES programs for facilitating limb control in the head-injured patient. Stimulator features that help ensure treatment success will be identified. The special cognitive considerations that must be addressed when using NMES on the head-injured patient will also be discussed. The …

Serial Casting: Clinical Applications For The Adult Head-Injured Patient, Cynthia Zablotny, Maureen Forte Andric, Charlotte Gowland

Faculty Publications - College of Physical Therapy

Serial casting has been used for over a decade to manage soft tissue contractures in patients with traumatic head injuries. Its use has also extended to the prevention of contractures in extremities exhibiting potentially deforming spasticity. This article will review the causes of soft tissue contractures and discuss how serial casting can manage such deformities. It will also identify how a serial casting program can be modified and integrated with other therapeutic efforts as the head-injured patient progresses physically and cognitively. Finally, it will address the timing and priority of casting in the patient's overall program.
