Objective: In this study, we aimed to determine the effects of 2-week neuromuscular electrical stimulation (NMES) on quadriceps muscle atrophy and lower extremity motor score in individuals with subacute incomplete cervical spinal cord injury (SCI). Methods: This stratified randomized controlled trial, conducted in the advanced critical care center of a university hospital, comprised 49 individuals with American Spinal Injury Association (ASIA) impairment scale grade C and D incomplete cervical SCI. The participants were stratified based on the ASIA impairment scale grade and randomly assigned to the control (n = 25) or NMES (n = 24) group. The control group participants received only conventional rehabilitation; the NMES group participants received conventional rehabilitation plus NMES in the quadriceps muscles of both lower limbs. The primary endpoints were quadriceps muscle thickness and L3 ASIA lower extremity motor score (L3 motor score), measured at the study’s initiation and after 2 weeks. Results: The quadriceps muscle thickness changes on the stronger and weaker sides were –14.2% ± 11.3% and –15.1% ± 13.8%, respectively, in the NMES group and –25.7% ± 16.8% and –26.0% ± 13.3%, respectively, in the control group, indicating significantly lesser reduction on both sides in the NMES group (p <0.05). The L3 motor scores on the stronger and weaker sides were 0.8 ± 1.2 and 1.3 ± 1.4 (NMES group) and 0.4 ± 0.8 and 0.4 ± 0.8 (control group), respectively, indicating significant improvement only on the weaker side (p <0.05). Conclusions: For subacute incomplete cervical SCI, 2 weeks of NMES reduces quadriceps muscle atrophy and improves the L3 motor score values on the weaker side compared with standard treatment.
