Abstract
BACKGROUND: Osteoarthritis of the knee causes pain and gait disturbances, as well as a distinct gait pattern. Patients with knee OA have decreased range of motion (ROM) and increased ground reaction force. OA reduces stride length and walking speed. OBJECTIVES: To determine the effect of a multi-component exercise program on pain-related gait adaptations among individuals with osteoarthritis of the knee joint and to compare the effect of multi-component exercises with traditional exercises on pain-related gait adaptations among individuals with osteoarthritis of the knee joint. MATERIALS AND METHODS: This was an experimental study done between 120 patients having knee OA, of both genders, and between the age group of 50-65 years. These individuals were residents of the city of Karad and they were randomly divided into group A (conventional/traditional) and group B (experimental). A pretest assessment was done and the treatment was given for 6 weeks. The later posttest assessment was done and further statistical tests like paired and unpaired t tests were used. RESULTS: Among the 120 subjects with OA knee, the age group of 60-65 years (44%) was found to be commonly affected. Thirty-nine were males (32.5%) and 81 were females (67.5%). Fifty-eight subjects (48%) were found to be commonly overweight. Thirty-two subjects (27%) had Genu Valgum deformity, and 88 subjects (73%) had Genu Varum deformity at the knee joint. The Pvalue within both group A and group B was found to be statistically significant for the entire outcome measures used for assessment. The pretest vs post test values of the WOMAC scale for patients with knee OA within both groups were found to be extremely significant (P < 0.0001). As for the MMT score in these patients, the Knee Flexors of Group A were not significant for right side (P = 0.7088) as well as for left side (P = 0.083) and in Group B they were extremely significant (P < 0.0001) for both sides. For the ROM scores within both groups, Knee Flexion of Group A for both sides was found to be extremely significant (P < 0.0001) for both sides. And for the pretest vs posttest values of within the groups'gait parameters among these patients with OA knees, for cadence both groups B were found to be extremely significant (P < 0.0001). The stride length for Group A was found to be very significant (P = 0.0060) and for Group B it was (P < 0.0001). Also, the P values of the various outcome measures between both groups were found to have statistical significance of their own. CONCLUSION: Effect of Multi-Component Exercise Program on Pain-Related Gait Adaptations Among Individuals with Osteoarthritis of the Knee joint was found to be significant in pain reduction, improving strength, range of motion, and the gait parameters such as an increase in cadence, stride length, step length and decrease in the step width.
