Purpose: This study was undertaken to compare the efficacy of instrument-assisted soft tissue mobilization (IASTM) and a neural dynamic technique (NDYT). As an intervention to treat spastic lower limb muscle tone, stiffness, and static balance in stroke patients.

Methods: Totally, 26 participants were assigned randomly to two groups: the IASTM (n=13) and NDYT (n=13) groups. Both groups were subjected to their respective technique for 15 minutes, 5 times a week, for 6 weeks. Muscle tone, stiffness, and static balance were evaluated before and after training, to compare both group changes.

Results: IASTM group showed significant decrease in the gastrocnemius medial region and semitendinosus muscle tone and stiffness (p<0.05) compare to NDYT group; however, no significant difference was observed in static balance between groups (p>0.05).

Conclusion: The results suggest that IASTM is an effective method for decreasing the muscle tone and stiffness in acute stroke patients.
