50대 이상 성인을 대상으로 한 탄력 및 비탄력 테이핑이 손과 손목의 근력, 근활성도, 손의 기능에 미치는 효과

Abstract

Background: Wrist stability is critical for maintaining functional independence in older adults. Age related declines in muscle strength and sensory feedback can lead to joint instability, impaired hand performance, and increased fall risk. Therapeutic taping may augment mechanoreceptor input, support joint alignment, and facilitate neuromuscular activation. This study compared the effects of elastic and non-elastic taping on grip strength, wrist muscle activation, and hand function in healthy elderly adults. Methods: Thirty five community dwelling adults aged 60–80 years were recruited; after two dropouts, thirty two completed a randomized, crossover protocol under three conditions: no tape, elastic tape applied per standard guidelines, and non-elastic tape for rigid support. Grip strength was measured with a hydraulic dynamometer. Surface EMG recorded activation of wrist flexor and extensor muscles during standardized tasks. Hand function was assessed via the Jebsen–Taylor hand function test, timing seven simulated daily activities. Each condition was separated by a five minute rest. Repeated measures ANOVA with Bonferroni correction examined differences at α = .05. Results: Elastic taping produced a significant increase in grip strength compared to no tape (p<.05), while non‑elastic taping did not, and no difference emerged between the two taping methods. Muscle activation did not differ significantly across conditions. Both elastic and non-elastic taping led to significantly faster hand function test completion times compared to no tape (p<.05), with no significant difference between them. Conclusion: Both elastic and non‑elastic taping improve hand performance in healthy older adults, with elastic taping additionally enhancing grip strength. These simple, safe, and low-cost techniques can serve as valuable adjuncts in early rehabilitation, helping to maintain wrist stability and prevent recurrent injury.
