Functional reach (FR) effectively measures balance changes during physical rehabilitation. This reliable test can detect improvements in balance over time, making it suitable for clinical trials.

Area of Science:

  • Gerontology
  • Rehabilitation Medicine
  • Biomedical Engineering

Background:

  • Functional reach (FR) is a validated measure of balance and physical frailty.
  • Assessing balance changes is crucial for evaluating rehabilitation effectiveness.

Purpose of the Study:

  • To evaluate the sensitivity of Functional Reach (FR) in detecting balance improvements over time.
  • To compare the responsiveness of FR with other mobility measures in a rehabilitation setting.

Main Methods:

  • Twenty-eight male veterans undergoing physical rehabilitation and 13 controls were assessed at baseline and every 4 weeks.
  • Measures included Functional Reach (FR) using the yardstick method, 10-foot walking time (WT), Duke hierarchical mobility skills (HMS), and Functional Independence Measure (FIM).
  • Responsiveness Index (RI) was used to determine the sensitivity to change for each measure.

Main Results:

  • Functional Reach (FR) demonstrated high sensitivity to change with a Responsiveness Index (RI) of 0.97.
  • Other tested measures, including WT, HMS, and FIM, were also sensitive to change, indicating their utility.

Conclusions:

  • Functional Reach (FR) is a sensitive and appropriate measure for detecting balance improvements in clinical trials.
  • FR, along with WT, HMS, and FIM, can be reliably used to monitor patient progress during physical rehabilitation.
