ABSTRACT
Background: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the world. 6MWT gives the patient’s walking ability whereas SCPT gives the patient’s ability to climb steps, which is dependent on lower limb muscle power. The Aim of this study was to determine the effect of lower limb strengthening on 6 Minute Walk Test & Stair Climb Power Test by incorporating progressive resistive exercises.
Method: 60 patients were enrolled for the study. The patients were recruited into control group and experimental group by simple random method. There were 33 patients in control group and 27 in experimental group. Both the groups were treated separately thrice in a week for 6 weeks. Experimental group received conventional physiotherapy and progressive resistive training of quadriceps and hamstring muscles by using 1RM .Control group received only conventional physiotherapy. 6MWT and SCPT were taken pre and post training in both the groups.
Result: In the Experimental group, the pre post comparisons of 6MWT, SCPT, 1RM Quadriceps and Hamstrings were done using the paired t test, there was a statistically significant increase in 6MWD, SCPT, 1RM (p=0.000, p<0.05). In control group paired t test were used and there was no significant increase in 6MWD, SCPT, 1RM for Quadriceps and Hamstring (p=.096, .152, .161, .161) respectively (p>0.05). The comparison of differences in 6MWT, SCPT, 1RM Quadriceps and Hamstrings between the experimental and Control groups were done using Mann Whitney U test. The experimental group showed increase in 6MWD, SCPT, 1RM for Quadriceps and Hamstrings compared to control group, which was statistically significant (p=0.000, p<0.05).
Key words: SCPT (stair climb power test), 6MWD (6 minute walk distance), RM (repetition maximum)
