2.2. Randomization
We randomized participants to Control and Experimental groups and also those who received left side measurements. Randomization was concealed from the recruiter and assessors using sealed opaque envelopes containing the allocation, which was generated earlier by a person independent from the study using random number tables, blocked to ensure equal numbers in both groups. The collection of some outcome measures required 2 assessors, who were blinded to group allocation, gave all instructions, and collected the outcome measures post-training.We followed the procedure for selecting and allocating cases advocated by the Consolidated Standards of Reporting Trials (CONSORT) guidelines (Fig. CONSORT flow diagram.
