Abstract

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 STS trials. Angular velocities at the hip, knee, ankle, and shoulder joints in successful trials exceeded those in unsuccessful trials (P

Conclusions: For this subject, sit-back failures occurred in STS attempts characterized by peak whole-body COM vertical velocities that were lower than those generated in successful rising trials. These unsuccessful rising attempts were primarily the result of the subject’s inability to generate sufficient knee extension angular velocity.
