Effect of Hard- and Soft-Density Insoles on the Postural Control of Adults over 65 Years of Age: A Cross over Clinical Trial.

BACKGROUND

there is a high risk of falls in older adults. One of the factors contributing to fall episodes is advancing age due to deterioration of the proprioceptive system. Certain clinical procedures improve balance and posture, such as the use of insoles.

OBJECTIVE

the objective of this study was to evaluate the impact of hard and soft insoles on static foot balance in healthy older adults compared to barefoot people.

METHODS

a clinical trial was conducted with a sample size of 150 healthy adults (69 male and 81 women) with a mean age of 69.03 ± 3.82 years. Postural control was evaluated in different conditions of barefoot balance with hard and soft insoles.

RESULTS

All tests were statistically significant ( < 0.001). The test with soft insoles presented higher stabilometric values and presented worse postural control compared to the barefoot and hard insoles in all eyes-open and eyes-closed conditions.

CONCLUSIONS

Hard and soft insoles show no improvement in postural control compared to barefoot standing. The findings suggest that soft insoles may result in impaired balance during standing. The density of the materials in the insoles emerges as a significant factor influencing postural control.
