Results: Statistical Analysis and Interpretation of Data

This chapter presents the statistical analysis and interpretation of the data collected to evaluate the effectiveness of Mobilization with Movement (MWM) and exercise interventions in patients with lateral epicondylitis. The collected data were analyzed using SPSS version 11 with a significance level set at 0.05. Statistical methods such as mean, standard deviation, paired t-test, and one-way analysis of variance (ANOVA) were used to assess both intra-group and inter-group differences among the three study groups.

The demographic analysis indicated that the majority of participants were male (65%) while 35% were female. The age distribution showed that most subjects were between 30–35 years of age. The study included three groups: Group A (Mobilization with Movement combined with ultrasound therapy), Group B (exercise therapy combined with ultrasound therapy), and Group C (ultrasound therapy alone).

Intra-group analysis revealed significant improvements in grip strength, pain levels, and functional ability in all three groups after the intervention period. However, the magnitude of improvement was greatest in Group A. Participants in Group A demonstrated a substantial increase in grip strength and a marked reduction in pain scores measured by the Visual Analogue Scale (VAS) compared to the other groups.

Intergroup analysis using ANOVA indicated statistically significant differences between the groups in post-treatment outcomes. The results showed that Mobilization with Movement combined with ultrasound therapy produced superior outcomes in terms of pain reduction, improvement in grip strength, and enhancement of functional performance when compared with exercise therapy and ultrasound therapy alone.

Overall, the statistical findings support the effectiveness of Mobilization with Movement as a beneficial physiotherapeutic intervention in the management of lateral epicondylitis. The results demonstrate that the treatment protocol used in Group A was more effective than the interventions used in Groups B and C.
