Objective To explore the impacts of proprioception, cutaneous sensitivity and strength on dynamic and static postural stability.Methods From June to November, 2020, a total of 164 elderly participated in this study. Independent parameters included proprioception of knee flexion/extension and ankle dorsi/plantar flexion with proprioception measurement; the cutaneous sensitivity of great toe, first and fifth metatarsals, arch, and heel with monofilament; and strength of ankle dorsi/plantar flexion and hip abduction with isokinetic test. The Berg Balance Scale (BBS) and center of pressure (COP)-based postural stability tests were conducted to represent dynamic and static postural stability. Exploratory factor and multivariable linear regression analyses were used to explore the relationship of each generated factor to postural stability outcomes.Results Proprioception was significantly correlated to the score of BBS (r=-0.449, P<0.001) and the root mean square (RMS) of COP in mediolateral direction (r=0.254, P=0.004). Cutaneous sensitivity was significantly correlated to the RMS of COP in the anteroposterior direction (r=0.281, P=0.002). Strength was significantly correlated to the score of BBS (r=0.493, P<0.001).Conclusion Proprioception and strength are related to dynamic postural stability, while proprioception and cutaneous sensitivity are associated with static postural stability.
