"A staff-like mobility aid used to assist a person with a disability to support their weight while walking. The device has one or more legs and a padded support or ""trough"" in a horizontal position for the user to rest the forearm. The hand wraps around a grip at the end of the forearm support. The device may be adjustable in length and is typically made of metal [e.g., aluminium (Al), titanium (Ti)]. This device is particularly suited to individuals who cannot rest their weight on their hands."
