Effects of Transcutaneous Electrical Nerve Stimulation with Taping on Wrist Spasticity, Strength, and Upper Extremity Function in Patients with Stroke: A Randomized Control Trial

초록

Objective: Six months after the onset of stroke, over 60% of patients experience upper limb dysfunction, with spasticity being a major contributor alongside muscle weakness. This study investigated the effect of transcutaneous electrical nerve stimulation (TENS) with taping on wrist spasticity, strength, and upper extremity function in patients with stroke. Methods: In total, 40 patients with stroke were included and randomly divided into two groups: the TENS + taping (n = 20, age 52.4 +/- 9.3 (range: 39 to 70)) and TENS (n = 20, age 53.5 +/- 10.8 (range: 39 to 74)) groups. All subjects performed 30 sessions of task-related training, which included 10 min of postural control training and 20 min of task performance. Additionally, all subjects received TENS on the spastic muscle belly for 30 min before task-related training. In the TENS + taping group, taping was additionally applied to the forearm and wrist but not in the TENS group. The Modified Ashworth Scale was used to measure spasticity, and a handheld dynamometer was used to measure muscle strength. The Fugl-Meyer Assessment of Upper Extremity was used to evaluate the functional ability of the upper extremity. Results: In the TENS + taping group, spasticity and upper extremity function were significantly improved as compared to those in the TENS group (p < 0.05). However, no significant difference in muscle strength was observed between the two groups (p > 0.05). Conclusions: This study demonstrated that the combination of TENS and taping for spasticity and function of the upper extremity was more effective in relieving the spasticity than TENS alone. Therefore, we suggest this combination as an additional treatment for spasticity and function of the upper extremity.
