A pointing task to improve reaching performance in older adults.

Area of Science:

• Gerontology
• Biomechanics
• Kinesiology

Background:

• The functional reach test is a common clinical measure of balance.
• Assessing functional reach is crucial for evaluating fall risk, particularly in older adults.
• Modifications to existing tests may improve their sensitivity and clinical utility.

Purpose of the Study:

• To investigate the effect of incorporating a pointing task on functional reach test performance.
• To compare the functional reach test with a modified pointing task in younger and older adults.

Main Methods:

• Twenty older adults (mean age 73 ± 8 years) and twenty younger adults (mean age 23 ± 1 years) participated.
• Participants performed a modified functional reach test that included a pointing task while standing on a force plate.
• The functional point test involved reaching and pointing at targets at maximal distance.

Main Results:

• Both age groups achieved greater reaching distances with the functional point test compared to the standard test.
• Older adults demonstrated increased anterior center of pressure displacement during the functional point test.
• Statistical significance was observed for increased reach distance in both groups (P = 0.001, P = 0.043) and for older adults' center of pressure displacement (P = 0.037).

Conclusions:

• Incorporating a pointing task enhances the functionality of the reach test and increases reaching distance.
• The functional point test may provide a more sensitive assessment of balance and fall risk.
• Further research is warranted to explore the stability limits and sensitivity of the functional point test compared to the traditional functional reach test.
