A quasi-experimental, one-group pretest–posttest time seriesresearch design was used to conduct a study among the patients attending OPD in selected hospitals. A total of 160 respondents were studied from October 2021 to February 2022. A numerical pain scale and a semistructured self-administered questionnaire were used to collect data. Only respondentswho gave informed consent were issued the questionnaire to complete at their convenience. Physical exercises were demonstrated and done by patients for 6 weeks, thrice a day in a week for 30 min regularly. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 24.0. Descriptive data were presented in the form of bar graphs and frequency tables.
Results:
The study showed that 59.37% of the respondents had severe LBP in the pretest. After doing selected physical exercises, the severe pain level reduced to 56.25% in post-test-1, 32.5% in post-test-2, and 14.37% in post-test-3. The t value of the difference in mean reduction of LBP was tabulated, and the calculated t values were (0.78, 5.60, 9.64) statistically significant at 0.05 level of significance ( P < 0.05).
