Study of Correlation between Lower Limb Strength, Handrail Height, Time Spent for Sit-to-Stand and Stand-to-Sit on Toilet Using Handrail for Elderly in a Province in Northeast Thailand

The aim of this study was to study the correlation between time spent sit-to-stand and stand-to-sit on the toilet and lower limb strength in the elderly. The samples used in this research were twenty-three males and eighty-eight females. They participated in this study after being informed by community leaders and posters. Methods used were measuring time in performing sit-to-stand and stand-to-sit movements. Five different handrail heights were used as one of the conditions in the experimental setup. The lower limb strength was measured by performing flexion and extension movements in the sitting position with maximum strength using torque measuring equipment. Pearson’s correlation between time and muscle strength was evaluated with the significance level (p-value) set at .05. Results showed that a range of Pearson correlation (r2) between the time consumed in stand-to-sit and sit-to-stand movement and the elderly’s lower limb extension and flexion strength was -0.360 to -0.614. The negative relationship indicates that the time needed for the acts of stand-to-sit and sit-to-stand movement increases as the lower limb strength decreases. Recommendations for further use of this research were drawn. To install handrails in bath rooms to reduce the elderly risk of falling, the handrail height should not be higher than 90 cm.
