“…Similar values were observed on a riding cyclist [18]. However, in the case of osteoporosis treatment, people are exposed to vibration with similar amplitude (3-10 m/s 2 ), but with both higher frequencies (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) and shorter exposure time (less than one hour per week distributed in 15 min sessions) [19].…”

“…As mentioned by Digiovine et al [55], frequencies between 2 and 8 Hz could be associated with individuals' natural frequencies and frequencies at 15-16 Hz to the MWC. This is supported by Skendraoui et al [39], who identified MWC eigenfrequencies at 16 Hz, 22-23 Hz, and 30 Hz through experimental modal analysis. However, for sport MWC's solely in dynamic conditions, frequencies lower than 15 Hz (i.e., 11-12 Hz) were observed for P f-Acc [36].…”

“…Therefore, participant mass seemed to mostly influence the repartition of the frequency content, but not the amount of vibration. Contrary to Skendraoui et al [39], over a drum shock simulator, Cooper et al [64] reported no difference in the PSD at the seat, neither for the amplitude nor the frequency, using dummies of different weights instead of real participants.…”

“…Articles that controlled input vibration observed various vibration properties. Input frequency was up to 15, 100, and 250 Hz for the work by authors of [30,38,39], respectively, while the amplitude varied from 0.4 to 2 m/s 2 , around 0.1 m/s 2 and up to 0.4 m/s 2 .…”

At 6 Hz, the PSD amplitude of the heavier participant (94 kg) was five-time lower than for the lighter participant (65 kg).…”

Manual wheelchair (MWC) propulsion can expose the user to significant vibration. Human body exposure to certain vibrations can be detrimental to health, and a source of discomfort and fatigue. Therefore, identifying vibration exposure and key parameters influencing vibration transmissibility during MWC propulsion is crucial to protect MWC users from vibration risks. For that purpose, a systematic review using PRISMA recommendations was realizedtosynthesizethe current knowledge regarding vibration transmissibility during MWC propulsion. The 35 retrieved articles were classified into three groups: Vibration content, parameters influencing vibration transmission, and vibration transmission modeling. The review highlighted that MWC users experience vibration in the frequency range detrimental/uncomfortable for human vibration transmission during MWC propulsion depends on many parameters and is still scarcely studied and understood. A modeling and simulation approach would be an interesting way to assist physicians in selecting the best settings for a specific user, but many works (modeling, properties identification, etc.) must be done before being effective for clinical and industrial purposes.

Manual wheelchair users are exposed to whole-body vibrations as a direct result of using their wheelchair. Wheels, tires, and caster forks have been developed to reduce or attenuate the vibration that transmits through the frame and reaches the user. Five of these components with energy-absorbing characteristics were compared to standard pneumatic drive wheels and casters. This study used a robotic wheelchair propulsion system to repeatedly drive an ultra-lightweight wheelchair over four common indoor and outdoor surfaces: linoleum tile, decorative brick, poured concrete sidewalk, and expanded aluminum grates. Data from the propulsion system and a seat-mounted accelerometer were used to evaluate the energetic efficiency and vibration exposure of each configuration. Equivalence test results identified meaningful differences in both propulsion cost and seat vibration. LoopWheels and SoftWheels both increased propulsion costs by 12-16% over the default configuration without reducing vibration at the seat. Frog Legs suspension caster forks increased vibration exposure by 16-97% across all four surfaces. Softroll casters reduced vibration by 11% over metal grates. Wide pneumatic 'mountain' tires showed no difference from the default configuration. All vibration measurements were within acceptable ranges compared to health guidance standards. Out of the component options, softroll casters show the most promising results for ease of efficiency and effectiveness at reducing vibrations through the wheelchair frame and seat cushion. These results suggest some components with built-in suspension systems are ineffective at reducing vibration exposure beyond standard components, and often introduce mechanical inefficiencies that the user would have to overcome with every propulsion stroke.
