“…Richter et al54 ) found reduced finger and wrist flexor activity during manual propulsion with the use of a flexible handrim, a metallic tube connected to the wheels through a flexible rubber membrane that reduces peak forces during initial contact. In a recent study, wheelchair users reported improved comfort and maneuverability with an ergonomic handrim that offers an increased surface for hand contact based on human anthropometric features55 ) .…”

Many aspects relating to equipment configuration affect users’ actions in a manual wheelchair, determining the overall mobility performance. Since the equipment components and configuration determine both stability and mobility efficiency, configuring the wheelchair with the most appropriate set-up for individual users’ needs is a difficult task. Several studies have shown the importance of seat/backrest assembly and the relative position of the rear wheels to the user in terms of the kinetics and kinematics of manual propulsion. More recently, new studies have brought to light evidence on the inertial properties of different wheelchair configurations. Further new studies have highlighted the handrim as a key component of wheelchair assembly, since it is the interface through which the user drives the chair. In light of the new evidence on wheelchair mechanics and propulsion kinetics and kinematics, this article presents a review of the most important aspects of wheelchair configuration that affect the users’ actions and mobility.

“…Due to the configuration of the propulsion rim, in inclined ground it requires greater use of the musculature to stabilize the grip rather than promoting power to the wheelchair propulsion (MEDOLA et al, 2012). This is due to the reduced diameter of the rim, which does not allow contact of the palmar region and requires fine handling…”

The aim of this study was to define design guidelines for an ergonomic adaptation in wheelchairs based on the upper limbs myoelectric activity evaluation of an experient manual wheelchair user, in flat and inclined grounds (ramp). The wheelchair use activity was carried out in a pre-established route that involved flat and inclined grounds (ascending). The data collection procedures were: socio-demographic questionnaire, hand grip dynamometry and surface electromyography. Therefore, the results found indicate, specifically, greater activity in the Flexor Digitorum Superficialis muscle groups bilaterally, which are the muscle groups responsible for assisting the manual grip on the wheel rim. In addition to this, there was a decrease in Medium Frequency values associated with an increase in the muscle use percentage, which may represent fatigue and inadequate physiological recovery of the muscle groups studied and may lead to severe musculoskeletal disorders. From the analysis of the physiological and biomechanical data, it was possible to identify biomechanical factors that may represent risks to the health of the wheelchair user, thus, design guidelines were suggested for an ergonomic adaptation that can reduce physical effort, mainly on inclined ground, aiming, specifically, to reduce the Flexor Digitorum Superficialis fatigue and increase the propulsion efficiency.

“…The device was qualitatively well received by end-users in this study [32]. In the realm of wheeled mobility, Medola et al used 3DP to develop a new type of wheelchair pushrim and then trialed it in a cohort of 6 participants [33]. All participants thought that the new pushrim improved ease of locomotion.…”

Created more than 30 years ago, 3-dimensional printing (3DP) has recently seen a meteoric rise in interest within medicine, and the field of Physical Medicine and Rehabilitation is no exception. Also called additive manufacturing (AM), the recent increase in the use of 3DP is likely due to lower-cost printers as well as breakthroughs in techniques and processing. This thematic narrative review serves to introduce the rehabilitation professional to 3DP technology and how it is being applied to orthoses, prostheses, and assistive technology (AT). The basics of the technology, as well as the benefits and challenges of using it within the rehabilitation framework, are described. Proponents of the technology suggest that 3DP offers not only a better way to make devices, but a better way to make improved devices. However, the strength of this claim has not been properly tested by the current literature. This narrative review evaluates the evidence and provides a discussion of possible implications for the rehabilitation professional.
