Arm Trough is a padded positioning accessory that attaches to a wheelchair armrest to support a hemiplegic or weak arm in a neutral, comfortable position. It prevents the affected arm from hanging unsupported at the side of the chair, reducing the risk of shoulder subluxation, edema, and skin breakdown in patients with stroke, neurological impairment, or upper extremity weakness.

Proper arm positioning is an important component of seating and pressure management programs for wheelchair users. The arm trough is adjustable in most configurations and compatible with standard wheelchair armrests. OxyCare supplies arm troughs and all wheelchair positioning accessories.
