Effects of neuromuscular and proprioceptive training on self-reported wellness and health scores and knee sensorimotor characteristics in active seniors

Abstract

IntroductionAthletes regularly engage in comprehensive neuromuscular and proprioceptive training (NPT) to prevent musculoskeletal (MSK) injuries. NPT exercises such as movement technique, agility, balance, and posture as well as yoga-based stretching and slow/deep breathing have shown added benefits in psychological and other well-being. This study aimed to examine the effects of NPT on knee sensorimotor characteristics and multi-domain wellness and health scores in active seniors. MethodsTwenty seniors participated in the NPT intervention (15–20min session twice a week for 10 weeks) while the control group did not receive any intervention. All participants completed surveys (general health, frailty, anxiety, stress, mindfulness, optimism, and sleep quality) and laboratory testing before and after intervention. Laboratory testing included frailty tests (grip strength, 4-m walk speed, and calcaneal ultrasound-based bone density) and knee sensorimotor characteristics (peak force, visual-motor reaction time, and force steadiness). ResultsThere was significant increase in general mental health (Short Form 36 Mental Health; p = 0.005) and decrease in stress (Perceived Stress Scale; p = 0.010) and sleep disturbances (Pittsburgh Sleep Quality Index; p = 0.019) post-intervention while no significant changes were observed in the control group (p = 0.310–0.654). Peak knee forces in all directions and some visual-motor reaction time and force steadiness were significantly improved post-intervention only in the experimental group (p = 0.001–0.038). ConclusionA simple, yet, comprehensive NPT has potential to improve MSK health as well as various domains of well-being among active seniors.
