Summary
This summary is machine-generated.

One-leg standing time (OLST) can predict hip fracture risk in elderly women. Longer standing time indicates a lower risk, suggesting OLST is a valuable tool for assessing fracture prevention needs.

Area of Science:

  • Gerontology
  • Orthopedics
  • Preventive Medicine

Background:

  • Hip fractures lead to reduced quality of life, immobility, and significant healthcare costs.
  • Impaired postural balance is a key risk factor for hip fractures in the elderly.
  • Existing fracture risk assessment tools like FRAX can be complemented by simpler measures.

Purpose of the Study:

  • To evaluate one-leg standing time (OLST) as a predictor of hip fractures in elderly women.
  • To compare the predictive ability of OLST with the established FRAX tool.
  • To determine if OLST can identify individuals needing fracture-preventive interventions.

Main Methods:

  • A cohort of 351 women aged 69-79 years underwent one-leg standing time (OLST) tests.
  • Participants were assessed using the FRAX fracture risk assessment tool.
  • Hip fracture data was collected retrospectively from registers.

Main Results:

  • A 5% decrease in hip fracture risk was observed for every second increase in OLST.
  • The relationship between OLST and hip fracture risk was found to be linear.
  • OLST demonstrated a predictive ability (Harrell's c = 0.68) comparable to FRAX (Harrell's c = 0.60) when adjusted for age.

Conclusions:

  • One-leg standing time (OLST) is a significant independent predictor of hip fracture risk in elderly women.
  • The predictive power of OLST is comparable to the FRAX tool, offering a simpler alternative.
  • OLST is a practical and valuable tool for assessing hip fracture risk and guiding preventive strategies.
