# Speed‐Dependent Interjoint Coordination During Treadmill Running in a Poststroke Athlete: A Case Report

## TL;DR

A poststroke athlete's injured leg shows rigid movement patterns during treadmill running, while the healthy leg adapts with speed, suggesting a need for targeted rehabilitation.

## Contribution

This case report identifies speed-dependent coordination changes in poststroke running, highlighting interjoint timing adaptations.

## Key findings

- The paretic limb exhibits rigid distal coupling during treadmill running.
- The nonparetic limb adapts its hip–ankle timing at speeds ≥ 6 km/h, with the ankle leading.
- Rehabilitation should focus on distal push-off and interjoint timing retraining for improved efficiency.

## Abstract

In a high‐functioning poststroke runner, the paretic limb shows rigid distal coupling, while the nonparetic limb adapts with speed; at ≥ 6 km/h, hip–ankle timing reverses (ankle leads). Prioritize distal push‐off and interjoint timing retraining to improve efficiency.
