Role of novel pressure sensor based alarm system in weight-shift behavior in spinal cord injury survivors - A time series

Pressure ulcers are a significant risk in SCI patients, with 25–66% of the survivors developing them. The World Health Organization (WHO) states that pressure ulcers are one of the most fatal complications in SCI patients. Pressure ulcer management involves repositioning, using pressure-relieving support surfaces, and appropriate nourishment. Patients with SCI often use wheelchairs for daily activities, increasing the risk of decubitus ulcers. To manage pressure ulcers, air in the cushion should be managed, and pressure sensors can be used to monitor pressure distribution, blood flow, and tissue oxygenation in patients. Hence, this study aimed to evaluate the effectiveness of a novel pressure sensor in reducing pressure ulcer risk in patients with spinal cord injury using the Braden scale and weight shifting behavior. It involved a time series procedure with a trial phase with community SCI centers, using the Braden Scale, a pressure alarm mat, and a clinician-reported log book. Results showed an exponential increase in weight shift frequency from pre-observation to post-observation phase, indicating a statistically significant difference.
