This research aims to prepare rehabilitation exercises according to the bio-kinematic analysis of the subtalar joint during the performance of monofin swimming to recovery from fibrosis of the ankle joint resulting from an unhealed fracture in monofin swimming. The study concluded that the Ultrasound and Shockwave sessions, in addition to Stretching for the two legs, are among the most important, inexpensive and effective ways to help the joint return to its natural state, and as a result, the joint returned to its normal position and regained its ability to perform its normal functional tasks efficiently. Conclusions
Subtalar joint fibrosis is considered in the problems that cause great pain in swimmers and limit the angle of action of the foot, which impedes its proper, correct and normal performance. Ultrasound and Shockwave sessions, in addition to Stretching for leg ailments, are considered one of the most important, inexpensive and effective ways to help the joint return to its normal state.
