“…This modular strategy thus augments fault tolerance and simplifies maintenance of the MPRC, positioning it as a preferable alternative to alternating pressure cushions as discussed in refs. [18,19,24], and marking the MPRC as a user-friendly option.…”

“…Active pressure redistribution cushions can dynamically adjust their shape, pressure distribution, and position in response to an individual's movements, weight, and body contours. Active pressure redistribution cushions commonly employ air or fluid‐filled chambers, [ 18 ] adjustable cells, [ 19 ] or electronic controls [ 20 ] to offer customizable and dynamic pressure relief. Most researched active pressure redistribution cushions focus primarily on alternating pressure seat supports, which cyclically inflate and deflate air cells to modify interface pressure.…”

Pressure ulcers, which can result from prolonged sitting, pose a significant challenge for wheelchair users. Soft robotics has considerable potential in preventing pressure ulcers. However, current soft robotics, constructed from flexible materials, face limitations including insufficient proprioception and controllability. Herein, a vacuum‐powered proprioceptive soft–rigid hybrid actuator (PSHA) module and a modular pressure redistribution cushion (MPRC) developed using this module are introduced. This PSHA module is capable of detecting both position and force. Each module within the MPRC is equipped with onboard control, proprioceptive sensation, and inter‐module communication. The MPRC incorporates a closed‐loop control system, enabling it to actively redistribute pressure, thereby preventing prolonged compression of local soft tissue during periods of inactivity. The proposed PSHA module, as evidenced in its application in pressure redistribution cushions, offers a promising approach for designs intent on reducing the risk of pressure ulcers. This study significantly contributes to the advancement of assistive technology, with the potential to enhance the quality of life for individuals with immobility or limited mobility.

“…Postural shifts, identi ed through analysis of ischial tuberosity data considering both sagittal and frontal movements, revealed that each posture adjustment increased subcutaneous oxygen saturation by 2.2% [21]. Movement facilitated by the air cushion enhances tissue blood perfusion and improves pressure distribution beneath the sitting area, possibly indicating a positive effect on tissue viability [22]. Additionally, a frequency of postural shifting 10 to 30 times per hour during sitting signi cantly reduced neck and lower back discomfort [23].…”

Background: Neck and low back pain are prevalent issues among office workers due to prolonged sitting, necessitating effective interventions. Dynamic seat cushion, designed to promote postural shifts have emerged as promising solutions to address these concern. This study aims to evaluate the effectiveness of a dynamic seat cushion on recovery and recurrence of neck and low back pain in office workers. Methods: This study used 6-month follow-up data of a randomized controlled trial, involving 66 office workers who reported pain in the trial. At baseline, participants were cluster-randomized into an intervention group, which received a dynamic seat cushion designed to encourage postural shifts, or a control group, which received a placebo seat pad. Health outcomes included recovery duration and recurrence of pain. Analyses utilized log rank test and Cox proportional hazard models. Results: In the intervention group, the recovery rate from neck and low back pain was 100%, which was 86% for the control group. The median recovery duration in the intervention group (1 month) was two months shorter than in the control group (3 months). The intervention group had a higher probability of recovery compared to the control group (HRadj 4.35, 95% CI 1.87 – 10.11; p < 0.01). The recurrence rate of neck and low back pain was 27% in the intervention group, which was 75% in the control group. The Hazard Ratio, after adjustment, for the intervention group compared to the control group was 0.50 (95% CI = 0.11 – 2.12). Conclusions: A dynamic seat cushion that encourages postural shifts shortened recovery duration of neck and low back pain among office workers. Due to small numbers, however, a potentially relevant reduction of recurrence of neck and low back pain could not be statistically confirmed.
