Music-based interventions (MBI), using music as a therapeutic medium, has been utilized as a promising strategy for motor relearning and shaping. However, currently, MBI with active performance training is restricted to being extensively applied for patients with various levels of defects in fine motor skills and cognitive functions. Therefore, the integration of vibrotactile stimulation with MBI has been adopted as a motor training strategy intended to enhance motor learning through use of vibration stimuli. The current study was designed to investigate differences in the sensorimotor performance of older adults' hands under baseline, a single session of active MBI, and vibrotactile-enriched MBI conditions.
Thirty healthy older adults were recruited and randomized to receive either the single session of 30-min of vibrotactile-enriched MBI or 30-min of active MBI at the beginning of the experiment. After a one-week washout period, they switched their treatment programs and then were assessed to study the training effects of both approaches through measuring precision pinch performance, hand function, and sensory status.
The results of the Pinch-Holding-Up Activity test revealed a statistically significant difference in the FR parameter (F = 14.37, p < 0.001, η = 0.507) under the vibrotactile-enriched MBI condition compared to the baseline and active MBI conditions. In addition, significant beneficial effects were found on the results of the barognosis (F = 19.126, p < 0.001, η = 0. 577) and roughness differentiation subtests (F = 15.036, p < 0.001, η = 0.518) in the Manual Tactile Test for the participants in the vibrotactile-enriched MBI group. In addition, the participants under both the active MBI and vibrotactile-enriched MBI conditions exhibited better performance in the three subtests of the Purdue Pegboard Test as compared to under the baseline condition (p < 0.016).
The findings indicated that vibrotactile-enriched MBI potentially improves the precision pinch performance of hands in healthy older adults. In addition, the add-on effect of vibrotactile stimulation to the MBI condition provides beneficial effects on the sensory functions of the upper extremities.

音乐干预（MBI），使用音乐作为治疗媒介，已被用作运动再学习和塑造的一种有前途的策略。然而，目前，具有主动运动训练的 MBI 仅限于广泛应用于精细运动技能和认知功能有各种缺陷的患者。因此，已采用振动刺激与 MBI 相结合的方法作为一种运动训练策略，旨在通过使用振动刺激来增强运动学习。本研究旨在调查在基线、单次主动 MBI 和振动增强 MBI 条件下，老年人手部的感觉运动性能的差异。
招募了 30 名健康老年人，并将其随机分为接受单次 30 分钟振动增强 MBI 或单次 30 分钟主动 MBI。在一周的洗脱期后，他们切换治疗方案，并通过测量精确捏合性能、手部功能和感觉状态来研究两种方法的训练效果。
在 Pinch-Holding-Up Activity 测试中，FR 参数（F=14.37，p<0.001，η=0.507）在振动增强 MBI 条件下与基线和主动 MBI 条件相比存在统计学显著差异。此外，在 Manual Tactile Test 中，棒状测试（F=19.126，p<0.001，η=0.577）和粗糙度区分子测试（F=15.036，p<0.001，η=0.518）的结果对振动增强 MBI 组的参与者具有显著的有益效果。此外，与基线条件相比，主动 MBI 和振动增强 MBI 条件下的参与者在 Purdue Pegboard Test 的三个子测试中的表现均有所提高（p<0.016）。
研究结果表明，振动增强 MBI 可能会改善健康老年人手部的精确捏合性能。此外，振动刺激对 MBI 条件的附加作用对上肢的感觉功能有有益的影响。
