The study aims to observe the effect of mechanical tarsal correction using Movement with Mobilization (MWM) in Amateur runners with tarsal hypomobility on foot biomechanical markers and load distribution percentage at the foot.
The study is based on finding foot faults by performing accessory joint mobility tests in the tarsal bones namely the talus, calcaneus, navicular, and cuboid. The pre-and post-intervention values were measured by Medial Longitudinal Arch Angle, Rear Foot Angle (measured using Angulus app), Navicular Drop as biomechanical markers, and load distribution percentage (measured by Curalgia Feet Sx Smart insoles) to find any improvements. 10 subjects were recruited for the study by criteria-based sampling, and finally, 6 subjects completed the study. Pre-test readings were recorded, and the study protocol began. Each patient received moist heat at the foot and ankle region, Short Foot Exercises along with MWMs to the hypomobile foot tarsal/s. The intervention was given for 6 sessions, on alternate days. Post-test results were recorded at the end of these 6 alternate days sessions.
Paired t-test was performed in MS Excel to compare the pre-and post-test values. With a 95% confidence interval, the p-value 0.05 was considered significant. While comparing the changes within the group, an improvement was observed within all biomechanical markers with p-value for MLAA= 0.002, RFA= 0.018, and Navicular Drop=0.0001 and the Load Distribution % (p=0.0056).
The pilot study showed a reduction in joint hypomobility and load distribution percentage in the tarsals when MWMs were performed for the hypomobile intertarsal joints.
The detection of these problems in the tarsals of the feet may help athletes perform better in competition and avoid injuries.
