The region in the brain affected by oxygen depletion of a stroke determines the severity and complexity of symptoms. A primary symptom is flaccid paralysis, which directly correlates to damaged brain cells capable of interactions with nerve and muscle cells. This paralysis refers to a complete lack of voluntary movement due to muscle weakness. Extensive support to limbs without muscular activity is necessary to eliminate the risk of further injury throughout the recovery period. Unaffected limbs can be used to support the weakened limb; however, this becomes burdensome for the individual. The use wheelchair components can provide limb support and recovery times without excessive exertion from the individual; however, current armrests incorporate thick, padded stabilizers with limited adjustability and customization. There exists a need for customizable options that allow for more comfort, support, and tension to the upper extremities of the patient.
Researchers at the University of New Mexico have developed an adjustable specialty armrest to replace standard wheelchair armrests. The armrest was developed for stroke patients experiencing flaccid paralysis or those with spastic complications. This device provides added support to the armrest wherein the patient's arm would otherwise sit restlessly. The suspension material is adjustable allowing for various tension levels to comfortably support the individual’s arm, eliminating muscular stress. The design is ambidextrous allowing the armrest to be utilized on both sides of a standard wheelchair.
