Abstract

Background: This study aimed to investigate the effects of neuromuscular electrical stimulation (NMES) of gluteus medius on hip function and sleep quality in patients with sleep disorders after hip arthroplasty (HA).

Methods: This retrospective analysis included 100 patients who underwent HA between January 2022 and August 2025 and developed postoperative sleep disorders. Patients were divided into in a control group (n = 45) and an NMES group (n = 55) based on the treatment received. The NMES group received NMES applied to the gluteus medius; both groups were treated for 4 weeks. Patient data extracted from the medical record system included hip function scores and sleep records: visual analogue scale (VAS), Harris Hip score, Berg Balance Scale (Berg) score, and Pittsburgh Sleep Quality Index (PSQI) score. These measures were compared between the two groups before and after treatment. Therefore, the correlation between VAS score and PSQI score was analysed.

Results: After treatment, hip function and sleep quality improved in both groups. VAS scores decreased significantly after 4 weeks of treatment in both groups (p < 0.05), with the NMES group showing lower scores than the control group (p < 0.05), Harris and Berg scores increased significantly in both groups(p < 0.05), and both were higher in the NMES group (p < 0.05). The PSQI score in the NMES group was lower than that in the control group (p < 0.05). Correlation analysisshowed a strongly positively correlated between VAS and PSQI scores in both groups before treatment (p < 0.05); after treatment, a weak positive correlation remained in the NMES group, whereas a moderate positive correlation persisted in the control group. 

Conclusions: Applying NMES to the gluteus medius is associated with reduced pain intensity in patients with sleep disorders after HA. This may contribute to improved sleep quality and help alleviate the reciprocal interaction between pain and sleep disorders.
