Vibration Transmitted to the Human Body during the Patient’s Ride in a Wheelchair

Abstract

The study investigates the spectra of vibrations transmitted onto the body of a wheelchair user during the ride on typical floor surfaces in public buildings and in their vicinity. Three wheelchair types are considered in the study (universal and active ones). Selected factors are examined that determine the amplitude of vibration acceleration acting upon humans in the analysed frequency range (wheelchair type, user's body mass, surface type). The spectral analysis gives an insight into some of the factors which lead to a change of the vibration parameters registered at the user's seat.

Vibration Transmission during Manual Wheelchair Propulsion: A Systematic Review

“…Poured concrete (i.e., the most common pedestrian pathway; see Surface 1, Table 6) is one of the surfaces that induced the highest amounts of vibration whatever the observed parameter (i.e., w-RMS, PSD, or P t-Acc ) [46,48,49]. Interior laboratory granite surface and poured concrete showed similar values in w-RMS (0.15 and 0.2 m/s 2 , respectively) [58]. Therefore, indoor and outdoor mostly used floors are those that induce the highest amount of vibration.…”

Vibration Characteristics Analysis of Convalescent‐Wheelchair Robots Equipped with Dynamic Absorbers

“…A new dynamic model for the wheelchair coupled with the user was developed and validated in [7]. e vibration transmission characteristics of wheelchairs and their effects on patients were analyzed in [8]. Hikmawan and Nugraha [9] simulated the vibration of a wheelchair under the sinusoidal excitation based on a 6 degree of freedom model of the wheelchair user.…”
