Can a Purposeful Walk Intervention with a Distance Goal Using an Activity Monitor Improve Individuals' Daily Activity...

Area of Science:

• Orthopedic Surgery
• Rehabilitation Medicine
• Geriatric Care

Background:

• High patient expectations for return to activity after total hip replacement (THR).
• Existing literature shows pain improvement post-THR, but limited objective data on daily activity enhancement.
• Need for evidence-based interventions to boost post-THR physical function in older adults.

Purpose of the Study:

• To assess the impact of an outdoor walking distance goal intervention on daily activity in older adults post-THR.
• To evaluate the effectiveness of a commercial activity monitor in guiding this intervention.
• To examine changes in gait, functional status, and psychosocial outcomes at 3 to 6 months post-THR.

Main Methods:

• Randomized pilot trial comparing an intervention group with a control group.
• Intervention group used a commercial activity monitor with a focus on outdoor walking distance goals.
• Outcome measures included objective activity levels, gait parameters, Hip Disability and Osteoarthritis Outcome Score (HOOS), and Psychosocial Impact of Assistive Devices Scale (PIADS).

Main Results:

• Participants in the intervention group demonstrated higher activity levels post-THR compared to the control group.
• Larger Cohen's effect sizes were observed in the intervention group for changes in gait, HOOS, and PIADS.
• The intervention showed a promising trend towards improved functional recovery and quality of life.

Conclusions:

• Targeting outdoor walking distance with activity monitors may enhance daily activity levels following total hip replacement.
• The intervention shows potential benefits for gait, hip function, and psychosocial adjustment.
• Further large-scale research is needed to confirm the significance of purposeful walking interventions versus simple step counting.
