- Abstract
This study was carried out to find the effects of 4-week and 2-week wobble board training in improving of muscle onset latency and perceived stability in basketball players diagnosed with recurrent ankle sprain, as there is decreased muscle onset latency of peroneus longus and tibialis anterior muscle and perceived instability following ankle sprains. Design Different subject experimental - Pre to Post test design. Setting Clinical setting. Participants Twenty seven male and three female recurrent lateral ankle sprain individuals. Outcome measure Surface EMG of PL (peroneus longus) and TL(tibialis anterior),this was measured during sudden 200 inversion using trap door mechanism, AJFAT(ankle joint functional assessment tool) questionnaire was used to rate each participant's perception of their ankle stability. Results The outcome difference of PL latency between Group A (2 weeks) (15.73+_6.01) and Group B(4weeks) (30.20+_6.44) shows a strongly significant difference and effect size is VL (very large) i.e.2.26 (p<0.001**). The outcome difference of TA latency between Group A (21.13+_11.47) and Group B (30.53+_8.48) shows a moderately significant difference and effect size is L (large) i.e.0.91(p<0.016*). The outcome difference of AJFAT between Group A (9.20+_3.29) and Group B (15.80+_3.45) shows a strongly significant difference and effect size is VL (very large) i.e.1.88 (p<0.001**). Conclusion Results demonstrated that the 4-weeks wobble board exercise programme significantly decreased muscle onset latency of the TA and PL in response to a sudden 20° ankle inversion as compared to 2 weeks wobble board exercise programme. Hence this study concluded that 4 weeks wobble board exercise was better than 2 weeks wobble board exercise training for improving muscle onset latency and perceived stability in ankle sprains.
