Abstract
Background Traditionally both rESWT and TENS are used in treating post-stroke upper limb spasticity over years and their effectiveness had been assessed disjointedly. However, these methods were not yet compared for superiority. Objectives To compare rESWT vs TENS to assess their effectiveness in different parameters of stroke such as stroke type, gender, and the affected side. Methods The experimental group was treated with rESWT application to the middle of the muscle belly of Teres major, Brachialis, Flexor carpi ulnaris, and Flexor digitorum profundus muscles using 1500 shots per muscle, frequency of 5Hz, energy of 0.030 mJ/mm. The TENS was applied to the same muscles in the control group using 100 Hz for 15 minutes. Assessments were taken at the baseline (T0), immediately after first application (T1), and at the end of four-week protocol (T2). Results Patients 106 with a mean age of 63.87±7.052 years were equally divided into rESWT (53) and TENS (53) groups including 62 males, 44 females, 74 ischemic, 32 hemorrhagic, affecting 68 right, and 38 left. Statistical analysis has revealed significant differences at T1 and T2 in both groups. But at T2 compared to T0; the rESWT group has reduced spasticity 4.8 times (95% CI 1.956 to 2.195) while TENS reduced by 2.6 times (95% CI 1.351 to 1.668), improved voluntary control by 3.9 times (95% CI 2.314 to 2.667) and it was 3.2 times (95% CI 1.829 to 2.171) in TENS group. Improvement of the hand functions of the rESWT group was 3.8 times in FMA-UL (95% CI 19.549 to 22.602) and 5.5 times in ARAT (95% CI 22.453 to 24.792) while thrice (95% CI 14.587 to 17.488) and 4.1 times (95% CI 16.019 to 18.283) in TENS group respectively. Conclusion The rESWT modality is superior compared to the TENS modality for treating chronic poststroke spastic upper limb.
