Self-ambulation helper and assistive rehabilitative device
The present invention relates to a self-ambulation helper and assistive rehabilitative device that is primarily designed to train the initial developmental phase of early life i.e., independent crawling. The device includes a tummy rest, a pair of forearm rest, a pair of leg rests, a left supporting rod, a right supporting rod, and a main frame. The tummy rest includes a tummy bracket, a top layer, and a pair of height adjusting mechanisms. The pair of forearm rest includes a left forearm rest and a right forearm rest. The pair of leg rest includes a left leg rest and a right leg rest. Each forearm rest and each leg rest include an adjustable strap and a base support. The device ensures reinforcement of biomechanically correct training patterns through repetitive practice at home for such patients.
