But what did the earliest version of this hand look like Neil Shubin pays a visit to. However, not much research work has been done on Physiotherapy and Ape Hand. Our hand has the same basic form as the hands of all other primates. Corresponding ranges are highlighted in red and green, respectively. (B) Thumb-to-fourth finger length ratios of modern apes and modern humans. Physical therapy helps to regain muscle strength while splints (C-splints) and braces help to recover. (A) Chimpanzee and human hand comparison. It is however possible to recover without treatment. Human hands are distinguished from apes by possessing longer thumbs relative to fingers. Occupational therapy, Physiotherapy and dynamic splinting which pulls the thumb in opposition may prevent excess in deformity. Animal paw vector animalistic pets claw or hand of cat or dog and. Surgery may be prescribed depending on the severity of the deformity, anti-inflammatory drugs and corticosteroid injections may also be used. Beautiful close up of the interaction with hands of a human with a Siamang (Symphalangus. Unlike the chimp’s hand, the uniquely designed human hand has a fully opposable thumb and is able to clench into a tight fist. There is a limited range of motion of the thumb. The chimpanzee’s hand (left) has much longer fingers, a longer palm, and a shorter thumb than the human hand (right). The condition is a part of median nerve palsy and it typically presents with problems moving the thumb in various planes. Humans also have an independent muscle / tendon dedicated to flexing. The mechanism of injury is a deep injury to the arm, forearm and wrist causing damage to the median nerve thereby causing impairment to the thenar muscles and opponens policis. Humans are the only ape which can achieve the full thumb tip to finger tip precision grip. Mechanism of Injury / Pathological Process The term "ape hand" is however misleading as apes have opposable hands but due to the limitations in the function of the thumb, some people believe it makes the hand looks like that of an ape. The thumb may also experience limited flexion and extension. ![]() The opposition is the ability of the first metacarpal to swing over the palmar surface of the hand so that the thumb and the tip of the little finger are in contact. ![]() Abduction of the thumb is the ability to move the perpendicular (90°) away from the plane of the palm. Since the thumb is not as long, it just meets up with the palm, while the chimps other four fingers extend upward. Ape hand is a physical deformity in humans causing an inability to abduct or oppose the thumb thereby causing the thumb little or no abduction and opposition. Conversely, chimp hands are much longer and narrower.
