With respect to static load, bathing and showering patients/residents is one of the most stressful tasks for caregivers.
Considerable reduction of strain when using a height-adjustable shower chair
The results of the study showed that caregivers using a fixed height hygiene chair for washing and showering patients/residents work less than 1/3 of the time, 31%, in a healthy posture, compared to 59% while using a height-adjustable shower chair.
Using a height-adjustable equipment is the preferred option from a workload perspective, but what about time?
A total of 67 washing activities were observed, and ‘washing in bed’ was the most time consuming, it took 474 seconds.
The caregiver had the greatest influence on the length of time it took. The second most important factor was the equipment used, while the patient variable was the least important factor.
