Pictorial comparison of the mean visual analog scale scores between the experimental and control groups at baseline, second, fourth, sixth, eightieth and tenth weeks. It shows the mean pain levels (visual analog scale scores) of the participants in both test/experimental and control groups across 10 weeks. Unlike in the control group, there was a continuous decrease in pain levels in the experimental group across the duration of the study. The baseline mean pain level for the test group was 6.23 ± 2.73 and after 10 weeks it decreased to 2.50 ± 3.23. The baseline mean pain level for the control group was 6.63 ± 2.30 and after 10 weeks it decreased to 5.50 ± 2.30
