Efficacy of instrument assisted soft tissue mobilization on chronic ankle instability

Abstract

Purpose. To investigate the effect of instrument assisted soft tissue mobilization (IASTM) on ankle pain, range of motion, balance, and Ankle and Foot Outcome Score (FAAOS) in patients with chronic ankle instability. Methods. Randomized controlled trial. Overall, 50 patients of both genders with age ranged from 16–30 years with chronic ankle instability were recruited and divided randomly into two equal groups; Group (A) (control group), received traditional physical therapy treatment (dynamic balance training) for 4 weeks, Group (B) (experimental group), received the same traditional PT treatment in addition to IASTM for 4 weeks. Pre- and post-treatment assessment using Visual analogue scale (VAS), Plastic goniometer, Biodex balance system and FAAOS were done for all patients. Results. The comparison between both groups post-treatment revealed statistically significant reductions in VAS, as well as overall stability index in favour of experimental group (B) (p < 0.001) and a significant increase in FAAOS, dorsiflexion, planter flexion, inversion and eversion range of motion in favour of experimental group (B) (p < 0.001). Conclusion. Instrument assisted soft tissue mobilization has a significant effect on reducing pain, increasing range of motion and improving balance and function in patients with chronic ankle instability.
