Grab Bar Use Influences Fall Hazard During Bathtub Exit

Area of Science:

• Gerontology
• Biomechanics
• Human Factors Engineering

Background:

• Injurious falls during bathing transfers are common, impacting self-sufficiency.
• Grab bars are recommended for bathing safety, but their fall prevention efficacy lacks evidence.

Purpose of the Study:

• To evaluate the hazard and strategies associated with grab bar use versus no grab bar use during unexpected balance loss while exiting a bathtub.
• To determine the effectiveness of grab bars in preventing falls during bathtub transfers.

Main Methods:

• Sixty-three adults performed a hazardous bathtub transfer task with unpredictable balance perturbations.
• Participants were divided into groups with and without grab bar availability; video analysis recorded slips and strategies.

Main Results:

• Grab bar users were 75.8% more likely to recover balance compared to non-users.
• Successful grab bar use was universally linked to balance recovery.
• Grab bar presence appeared to cue environmental stability strategies.

Conclusions:

• Grab bars offer effective support for recovering from unexpected balance loss.
• The presence of grab bars may promote proactive fall prevention strategies.
• Integrating grab bars into bathroom designs can decrease fall-related injuries during bathing transfers.
