The effect of occupation-based postural stability training on postural stability and occupational performance in visually impaired individuals: A randomised controlled trial
The purpose of this research was to examine the effect of occupation-based postural stability training on occupational performance and postural stability in visually impaired individuals.
Method
The research was designed as pre-test/post-test, with two groups (study group and control group). A total of 34 individuals with visual impairment were randomly assigned to the two groups. Participants were evaluated using a sociodemographic information form, the Biodex Balance System for postural stability, the Canadian Occupational Performance Measurement for assessing performance and satisfaction of occupations and the semi-structured interview form. The control group received only postural stability training with the Biodex Balance System and the study group received individualised occupation-based postural stability training with the Biodex Balance System BBS during a 12-week intervention (24 sessions).
Results
A statistically significant difference was found between the postural stability values of the study group and the control group when looking at pre and post-training measurements (p < 0.05). It was observed that there was an improvement in the postural stability of the participants in both groups. There was a statistically significant increase in the occupational performance and satisfaction of participants in the study group (p < 0.01).
Conclusion
Adding person-centred, meaningful and purposeful occupations into rehabilitation programmes that use technological devices increases functionality in activities of daily living.
