Application of Surface Electromyography (sEMG) in the Analysis of Upper Limb Muscle Activity in Women Aged 50+ During Torqway Riding
Sylwia Agata Bęczkowska, Iwona Grabarek, Zuzanna Zysk
TL;DR
This study uses sEMG to analyze upper limb muscle activity in older women during simulated riding of a mobility device.
Contribution
The study pioneers the use of sEMG for biomechanical analysis of a new mobility device for older adults.
Findings
Muscle activity (RMS) was significantly higher during the active phase compared to the passive phase.
MPF values decreased over time, indicating muscle fatigue during the activity.
sEMG shows potential as a tool for evaluating ergonomics and muscle effort in mobility device design.
Abstract
The aim of this study was to analyze the activation of selected upper limb muscles. For the purposes of this article, we present results concerning the following muscles: triceps brachii, anterior and posterior deltoid, and trapezius in women aged 50 and above during simulated riding of the Torqway device, using surface electromyography (sEMG). The primary objective was to compare muscle activity across two movement phases: active and passive. Accordingly, the following research hypotheses were formulated: muscle activity (measured by RMS values) will be significantly higher during the active phase compared to the passive phase, and MPF (mean power frequency) values will decrease over time, indicating the onset of muscle fatigue. Additionally, the potential of surface electromyography was assessed as a diagnostic tool for evaluating ergonomics and muscle effort in the context of…
