Effects of scapular taping on grip strength and hand function: a randomized controlled cross-over study

Grip strength and hand function are critical for upper extremity performance. Although scapular stability is essential for upper extremity functioning, the effects of scapular taping on hand function and grip strength remain unknown.

Investigating the immediate effects of scapular taping techniques on grip strength and hand function in healthy individuals.

Fifty-nine participants (22.15 ± 1.35 years) received Kinesio Taping (KT), Rigid Taping (RT), and Sham Taping in random order with a three-day washout. Grip strength (gross grip, 2-point, 3-point, lateral pinch) and, hand function (Purdue Pegboard Test (PPT), Moberg Pickup Test (MPT), and Minnesota Hand Dexterity Test (MHDT) were conducted immediately after interventions.

RT statistically significantly increased 2-point, and 3-point pinch strength compared to the sham taping (p = .006, d = 0.19, p = .031, d = 0.30). No statistically significant differences were observed in remaining outcomes (p > .05). There were no statistically significant differences between KT-RT or KT-Sham in any of the outcome measures (p > .05, d < 0.2). A moderate negative correlation was detected between 3-point and lateral pinch strength and the PPT Both Hands sub-score (r=-0.372, p = .044; r=-0.351, p = .006). A weak negative correlation was found between gross grip strength and the MPT Eyes Open sub-score (r=-0.294, p = .024).

This study demonstrates the effect of scapular taping on enhancing fine grip strength and offers a potential approach to improving distal performance of the upper extremity. Further research involving diverse populations, and long-term follow-up is needed to validate these findings and determine their potential implications for clinical practice.
