Which condition is a contraindication for a reciprocal gait orthosis (RGO)?

A reciprocal gait orthosis (RGO) is specifically designed to aid individuals with lower extremity disabilities, providing assistance for walking by coordinating the movement of the legs in a reciprocal manner. This type of orthosis relies on a certain level of body composition and biomechanics to function effectively.

Obesity serves as a significant contraindication for the use of an RGO. The additional weight can impose excessive demands on the orthotic systems, which are designed to support a specific weight limit while maintaining the stability and functionality necessary for proper movement. Increased body mass can also lead to greater instability while using the device, increasing the risk of falls or difficulties while ambulating. Excess weight may compromise the efficacy of the orthotic and can potentially lead to mechanical failure, putting undue stress on the user.

In contrast, reliable family support and adequate upper extremity strength are beneficial for individuals utilizing an RGO as they can enhance mobility and independence. Minimal hip flexion contractures indicate a range of motion sufficient for using the orthosis effectively and do not present the same level of risk as obesity.
