Objectives: This study aims to examine the characteristics of muscle activity change of the tibialis anterior (TA) muscle in healthy adults while they walked on a split-belt treadmill with one fixed ankle.
Patients And Methods: This randomized controlled trial was conducted between November 2017 and July 2018. Fourteen healthy male individuals (mean age 31.
Article Synopsis
- Loss of motor coordination is a significant issue for stroke patients, often evaluated through muscle synergy, which reflects their ability to control movements.
- Recent research utilized nonnegative matrix factorization (NNMF) to analyze muscle synergy in subacute stroke patients, involving two measurements to track changes over time.
- Findings indicated that while the number of muscle synergies didn't necessarily correlate with functional improvements, the merging of these synergies was linked to enhanced muscle strength and ankle joint movement, suggesting that this merger could be a key indicator of recovery post-stroke.
Introduction: Increased ankle muscle coactivation during gait is a compensation strategy for enhancing postural stability in patients after stroke. However, no previous studies have demonstrated that increased ankle muscle coactivation influenced ankle joint movements during gait in patients after stroke.
Purpose: To investigate the relationship between ankle muscle coactivation and ankle joint movements in hemiplegic patients after stroke.
Background: Increased ankle muscle coactivation during gait represents an adaptation strategy to compensate for postural instability in adults after stroke. Although increased ankle muscle coactivation is correlated with gait disorders in adults after stroke, it remains unclear which physical impairments are the most predictive clinical factors explaining ankle muscle coactivation during gait.
Objective: To investigate these physical impairments in adults after stroke using stepwise multiple regression analyses.
Increased ankle muscle coactivation during gait has frequently been observed as an adaptation strategy to compensate for postural instability in adults after stroke. However, it remains unclear whether the muscle coactivation pattern increases or decreases after balance training. The aim of this study was to investigate the immediate effects of balance practice on ankle muscle coactivation during gait in adults after stroke.
