The effect of quadriceps neuromuscular electrical stimulation on pain scores, functional testsand quality of life in military personnel with partial anterior cruciate ligament tears

Anterior cruciate ligament (ACL) rupture is one of the most common knee injuries. This study aimed to evaluate the effect of quadriceps neuromuscular electrical stimulation (NMES) on pain scores, functional tests, and quality of life in military personnel with partial ACL ruptures. A total of 60 male military patients with knee pain were divided into two groups: an intervention group receiving NMES and a control group without NMES. Both groups underwent standard treatments, including infrared therapy, ultrasound, and quadriceps strengthening exercises. Evaluations were performed before and after treatment for pain reduction (VAS scale), quality of life (QOL ACL questionnaire), and a 10-meter walk test. Data were analyzed using SPSS software. The mean VAS score in the NMES group decreased from 3.57 ± 1.25 to 1.07 ± 0.9, while in the control group it decreased from 3.6 ± 1.07 to 2.64 ± 1.66 (P < 0.001). The QOL scores improved from 32.08 ± 10.5 to 59.83 ± 6.9 in the NMES group and from 31.03 ± 9.8 to 41.6 ± 7.1 in the control group (P < 0.001). No statistically significant difference was observed in the 10-meter walking test between the groups. Quadriceps NMES appears to be a promising intervention for reducing pain, improving muscle function, and enhancing the quality of life in patients with partial ACL ruptures.
