Abstract

Background: Foot pronation is a series of movements which is intended to absorb shock by decelerating and cushioning the foot as it comes in contact with surface. When this motion is exaggerated, the ankle rolls too far inward and the arch is flattened causing overpronation. It is seen that with an abnormal pronation, navicular drop occurs. Navicular drop causes pain in ankle and knee, fatigue, difficulty in walking. The purpose of the study was to determine the effect of intrinsic muscle strengthening with orthosis over conventional physiotherapy exercises with orthosis for correction of navicular drop and Pain Disability in prolong standing workers.
Method: An Experimental study design, seventy industrial workers were tested for navicular drop test out of which fifty tested positive. The subjects were divided into two groups Group A (N=25) and Group B (N=25). Group-A subjects received intrinsic muscle strengthening exercises with orthosis and Group-B received conventional physiotherapy exercises with orthosis. The duration of treatment continued was given for 8 weeks and outcome measurements were measured at 0 day, 4th week and 8th week using the Navicular drop (ND) test and Pain Disability Questionnaire (PDQ).
Results: Comparative analysis using Independent t-test was carried out separately for ND and PDQ. For ND, t =-5.01 which is highly significant (p=0.00). It has been inferred that ND decreases more when intrinsic muscle strengthening with orthosis was applied. To see the difference of means of PDQ, t = -1.97 which is significant (p = 0.049) implying that PDQ decrease more when intrinsic muscle strengthening was applied as compared to conventional physiotherapy with orthosis.
Conclusion: It is concluded that 8 weeks of intrinsic muscle strengthening exercise with orthosis is more effective than conventional physiotherapy exercises with orthosis in reducing navicular drop and improving Pain Disability in prolong standing workers.
