Exploring the efficacy of neural mobilization and electromyographic analysis in enhancing post-stroke rehabilitation: A scoping review

Abstract

Stroke survivors often suffer from upper limb spasticity and impaired motor function. This review seeks to: (1) explore the efficacy of neural mobilization, particularly using the Upper Limb Neurodynamic Test 1 (ULNT1), in modulating electromyographic (EMG) activity of muscles; (2) examine its role in reducing spasticity and improving functional outcomes; and (3) outline the current state of knowledge, identifying existing gaps and directions for future research. A comprehensive literature review was conducted, focusing on studies that implemented ULNT1 and EMG analysis in post-stroke patients. The included studies varied in participant characteristics, methodologies, and outcome measures. The results demonstrated that neural mobilization has the potential to reduce EMG activity in spastic muscles and modify pain perceptions. However, results regarding the improvement of range of motion and functional outcomes were mixed. Neural mobilization and electromyographic analysis show promise for improving post-stroke rehabilitation. However, further research is required to confirm these benefits, with more rigorous methodologies and larger sample sizes.
