EFFECT OF FUNCTIONAL EXERCISE ON MUSCLE STRENGTH, BALANCE, POWER, AND AGILITY IN ELITE RUGBY PLAYERS WITH CHRONIC ANKLE INSTABILITY

Phase 1

Completed

• Conditions: Chronic ankle instability (CAI); Functional exercise; Chronic ankle instability; Muscle strength; Balance; Power; Agility

• Registration Number: TCTR20210213004
• Lead Sponsor: Faculty of Allied Health Sciences Thammasat University, Rangsit Center

Brief Summary

FE group were improved muscle strength of LEs (ankle plantar flexor, knee flexor, hip abductor, hip external rotator, and hip extensor) and VJT after training. Whereas, ankle evertor, ankle invertor, knee flexor, hip abductor, and hip external rotator were improved in CT group. Both groups improved SEBT in anterior and posteromedial directions. However, the results were no significant difference in the agility test. CAIT scores was improved within CT group and between both groups after 6 weeks.
