简要总结
The goal of this clinical trial is to exploratorily evaluate the safety and efficacy of a home-based lower extremity muscle strengthening and physical performance enhancement program using Neuromuscular Electrical Stimulation (NMES) devices.
Participants will apply NMES stimulation to both thighs for 8 weeks, at a frequency of at least 4 times per week.
详细描述
Neuromuscular electrical stimulation (NMES) is a non-invasive, non-surgical, and non-pharmacological intervention that delivers electrical stimulation to superficial skeletal muscles to activate motor nerves, thereby inducing muscle contractions without voluntary effort. In patients with sarcopenia, aging and reduced physical activity lead to progressive declines in muscle mass and strength. This deterioration is closely associated with increased risk of falls, greater physical dependency, and reduced quality of life. In particular, lower extremity muscles-especially the quadriceps-are well-known predictors of gait speed, and maintaining muscle mass and strength in these muscles is critical for improving clinical outcomes.
To date, most studies on NMES have been conducted in older adults, and clinical research specifically targeting patients diagnosed with sarcopenia remains limited. Therefore, this study aims to exploratorily evaluate the safety and efficacy of a home-based program using an NMES device to improve lower extremity muscle strength and physical performance in patients with sarcopenia.
