Faculty Publications - College of Physical Therapy

Comparison between successful and failed sit-to-stand trials of a patient after traumatic brain injury.

Objective: To compare the peak whole-body center of mass (COM) velocities and joint angular contributions in successful and unsuccessful sit-to-stand (STS) trials in a subject with traumatic brain injury (TBI).

Design: Single-case study.

Setting: Motion research laboratory.

Participant: A 24-year-old man who was 3.5 years post-TBI.

Interventions: Not applicable.

Main Outcome Measures: Peak horizontal and vertical velocities of the whole-body COM and peak angular velocities of the ankle, knee, hip, and shoulder joints.

Results: The peak whole-body COM vertical velocity was significantly lower in the unsuccessful …

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 …
