Analysis of Mechanical Loads acting on Handrail when Stair Climbing Using Both Hands

Abstract

Handrails are frequently installed in public facilities. In this research, we analyzed mechanical loads acting on stair handrail using both upper limbs during stair climbing. Seven healthy right-handed adults (age: 23.9±5.0 years, height: 170.1±6.3 cm, weight: 56.2±7.3 kg) participated in the experiment, stair climbing while using their right and left hands. As a result, the handrail was gripped with approximately 126.2 N by the right-hand, and approximately 119.3 N by the left-hand gripped during the ascending motion. In future studies, we plan to conduct experiments with elderly individuals who require handrails.
