Neuromuscular electrical stimulation (NMES) could provide an alternative or adjunct treatment modality to induce muscle hypertrophy in the hip osteoarthritis population. This preliminary study evaluates the feasibility and acceptability of NMES to evoke involuntary muscle contractions in adults with advanced hip osteoarthritis.
Thirteen adults with moderate-to-severe hip osteoarthritis and fifteen healthy, older adults were invited to a lab-based testing session. NMES was applied unilaterally to the knee extensors and hip abductors for one continuous, five-minute testing session. Data were collected on device acceptability, tolerability and muscle contractile force, and compared between groups.
Electrical stimulation of the knee extensors elicited a visible muscular contraction in 11 participants (85%) with hip osteoarthritis and 15 controls (100%) at an intensity acceptable to the participant. Electrical stimulation of the hip abductors elicited a muscular contraction in eight participants (62%) with osteoarthritis, and ten controls (67%). Muscle contractile force, pain, discomfort and acceptability did not differ between groups, however NMES of the knee extensors was favoured across all measures of assessment when compared to the hip abductors.
Electrical stimulation of the knee extensors may be a feasible and acceptable treatment modality to address muscle atrophy in adults with advanced hip osteoarthritis.
神经肌肉电刺激（NMES）可为髋骨关节炎患者诱导肌肉肥大提供一种替代或辅助治疗方式。这项初步研究评估了NMES在晚期髋骨关节炎成人患者中诱发非自主肌肉收缩的可行性和可接受性。
邀请了13名中重度髋骨关节炎成人患者和15名健康的老年人参加基于实验室的测试环节。将NMES单侧应用于膝伸肌和髋外展肌，进行一次持续5分钟的测试。收集有关设备可接受性、耐受性和肌肉收缩力的数据，并在两组之间进行比较。
在参与者可接受的强度下，对膝伸肌进行电刺激时，11名髋骨关节炎患者（85%）和15名对照组参与者（100%）出现了明显的肌肉收缩。对髋外展肌进行电刺激时，8名骨关节炎患者（62%）和10名对照组参与者（67%）出现了肌肉收缩。两组之间的肌肉收缩力、疼痛、不适和可接受性没有差异，然而，与髋外展肌相比，在所有评估指标中，膝伸肌的NMES更受青睐。
对膝伸肌进行电刺激可能是治疗晚期髋骨关节炎成人患者肌肉萎缩的一种可行且可接受的治疗方式。
