The Archives of Physical Medicine and Rehabilitation recently published research on the use of a new, manual wheelchair equipped with rear anti tip device as compared to a traditional "tilt in space" wheelchair.  Caregivers tested the two chairs.  It was reported that the manual wheelchair with the rear anti tip device had better wheelchair handling, wheelchair satisfaction and less exertion.
