<h3>Compensatory strategy for improving independence with self-feeding</h3>

Explanation:

Limitation of shoulder or elbow range of motion due to fracture, dislocation or an injury like a burn injury will lead to flexion contracture.

This limits the patient’s ability to flex or extend the elbows freely to perform activities of daily living (ADL) like self-feeding, self-grooming etc.

Such patients should be assisted with supportive compensatory strategies to and improve their independence by aiding them perform their own ADLs.

Appropriate positioning of the patient and adjusting the height of the food table while eating, trunk swaying, tabletop propping, elbow orthoses like custom-cuffs, dynamic elbow orthoses, feeding utensils with customized handles to hold, robotic arm, and other mechanized orthoses can be utilized to improve independence with self-feeding.
