Trial Outcomes & Findings for Telerehabilitation Gait Modification (NCT NCT04683913)

NCT ID: NCT04683913

Last Updated: 2024-12-04

Results Overview

Change in foot rotation angle between baseline and week 6 (follow-up) appointments measured using marker-based motion capture. Foot rotation is defined as the angle between the long axis of the foot and the walking direction. Measures of central tendency and variability will be extracted.

Participant Flow

Two recruitment drives were completed using online social media outlets between January 2021 and May 2021. The drives garnered 134 respondents (72 and 62, respectively) who were preliminarily screened for study inclusion/exclusion. Sixty individuals underwent radiographic screening and 28 underwent biomechanical screening for response to gait modification. A total of 20 participants completed baseline assessments and were randomized.

Participants completed a biomechanical screen involving normal and modified walking in a motion capture space. The data were used to calculate the knee adduction moment impulse (main biomechanical outcome) and foot progression angle (modification target). Those who did not reduce their knee adduction moment impulse \>5% were not included in the study.

Measure
Immediate Intervention: Telerehabilitation
Immediate entry into the gait modification intervention delivered using teleconferencing methods Foot rotation modification: The instruction of gait modification provided via teleconferencing sessions (5 over 6 weeks) focusing on increasing toe-in or toe-out angles by "as much as is comfortable".
Delayed Intervention: Telerehabilitation
Delayed (6 weeks) entry into the gait modification intervention delivered using teleconferencing methods Foot rotation modification: The instruction of gait modification provided via teleconferencing sessions (5 over 6 weeks) focusing on increasing toe-in or toe-out angles by "as much as is comfortable". Waiting Period - Delayed Group: Participants allocated to the Delayed Group will wait 6 weeks after their initial baseline, then complete a second baseline to provide a control condition. After the second baseline they will enter the intervention.
