Figure 0:15 Goniometric measurement of shoulder ROM
2. Shoulder pain intensity was measured in various activities involving the shoulder. The participants were asked to mark the pain
intensity for each activity on separate visual analogue scales. The right end of the VAS was defined as "worst pain imaginable’’, the
left end as "no pain ". Each level was recorded in a table (Table). A score was then calculated out of 100 with higher scores
reflecting higher pain levels.
3. Shoulder disability level was measured in various activities involving shoulder. The right end of the VAS was defined as "so
difficult required help", the left end as "no difficulty".The level of difficulty in doing each activity is marked in the table. A score
was then calculated out of 100 with higher scores reflecting higher disability levels.
03.8 Ethical clearance
Ethical clearance was obtained by requesting from the ethical review committee of the faculty of Allied Health Sciences,
University of Peradeniya.
03.10 Data analysis
All analyses were performed with MINITAB statistical software (version14). Frequency distributions as well as means and standard
deviations were used for descriptive purposes. At the baseline, differences in age was analysed using the two-sample Wilcoxon rank
sum test. Differences between treatment groups in change scores at the baseline and at the end of each treatment sessions over a period
of 3 consecutive weeks were analysed with the two-sample Wilcoxon rank sum test. Repeated measurements obtained before and after
treatments within groups were also analysed with the two-sample Wilcoxon rank sum test. The Kruskal Wallis test was performed to
estimate differences between age groups for each studied outcome. The alpha level for significance was set at 0.05.
IV. RESULTS
Distribution of age groups among control and intervention groups
The age of the participants of both the control and intervention groups ranged from 18-55. The above age group was categorized into 4
groups.
