Effect of multidirectional and unidirectional wobble board lateral step-upexercise in pain, symptom and ADLamong unilateral medial compartmental osteoarthrosis of knee

Introduction and Aim: Osteoarthrosis is defined as degenerative condition of the synovial joints. Weak thigh muscle will cause impaired walking and balance and leads to risk of fall during activities of daily living. Use of MD and UD wobble board is hypothesized to improve balance and proprioception. So, pain, muscle power and proprioception are clinically important for balance control. Hence there is a need to study weight bearing exercise to hip abductor in various balance strategies to achieve muscle strength, joint position sense, balance, and activity of daily living.   Methodology: Knee osteoarthrosis subjects(n=219) were selected according to selection criteria and were randomly allocated into 3 groups as multidirectional wobble board lateral step-up exercise group, unidirectional wobble board lateral step-up exercise group and control group. The pre-test KOOS pain, symptoms and ADL measurements were taken before the intervention and another measurement during the 2nd week of intervention and at the end of the intervention period during 4thweek post-test measurements were measured and statistically analysed.   Results:  At the end of 4th week control, UD and MD was found to be statistically significant with H=200.192 with p<0.001. KOOS symptoms between 3 groups was found to be statistically significant with H=200.288 and p <0.001. KOOS ADL values was found to be statistically significant between 3 groups with H=193.640 and p<0.001.   Conclusion: This study concludes that both unidirectional and multidirectional wobble board lateral step-up exercise showed improvement with KOOS pain, symptom and ADL scores compared to control group.
