Skeletal deformities in the elderly and their effect on postural sway

Area of Science:

• Gerontology
• Biomechanics
• Orthopedics

Background:

• Postural sway, a measure of balance, is crucial for elderly mobility and fall prevention.
• Age-related changes in physical attributes and skeletal structure can affect balance.
• Understanding these relationships is key to developing targeted interventions.

Purpose of the Study:

• To investigate the correlation between various physical attributes and skeletal deformities with postural sway in elderly individuals.
• To identify specific factors contributing to balance impairments in older adults.

Main Methods:

• A cohort of 151 elderly participants (65-85+ years) was assessed.
• Measurements included weight, height loss (span-height), scoliosis, grip strength, and lateral knee angle.
• Postural sway was quantified and analyzed against these physical parameters.

Main Results:

• Weight, height loss, scoliosis, grip strength, and knee angle were significantly correlated with increased postural sway.
• Kyphosis showed a relationship with reduced muscle power and frailty indicators.
• Scoliosis was associated with pelvic and lower limb joint disease.

Conclusions:

• Physical attributes and skeletal deformities are significant determinants of postural sway in the elderly.
• Interventions addressing weight, spinal alignment, and lower limb function may improve balance in older populations.
• Further research into the biomechanical impact of these factors is warranted.
