The participants were screened according to the eligibility criteria and included according to the intention to treat principle.
Patients were randomly allocated into two groups using the chit box method a simple method of generating random sequence.
To ensure equal treatment groups, we prepared 40 chits writing A (for Group A) on 20 chits and B
(for Group B) on 20 chits.
After folding the chits and putting in a box and mixing well, the researcher drew a chit, noted
the letter written on it, and then drew the second chit without replacing the first, noted it and proceeded similarly until the last chit was drawn [14].
Two experienced physiotherapists were assigned for the measurement of the data and implementation of the intervention programmes separately (i.e., the assessors were not involved in their treatment).
It was a double-blinded study. The assessor and treating therapists were unaware of the group assignment.
