Forearm and wrist supination/pronation is

closely related to function. 

Degenerative and traumatic processes not to mention

surgical treatments can lead to a reduction in range

of movement.

Traditionally we make estimates based on clinical

judgement and experience but quantifying this ROM

is far more involved.

The current ‘Gold Standard’ Involves taking photographs

with the ‘patient’ holding a cane in the hand with a ‘plumb line’

and then measuring the angle between the two.  Not

teribly practical in the busy fracture or orthopaedic clinic!

WristGoni

WristGoni is a Goniometer to

measure supination and pronation

reproducibly and accurately

using the iPhone /

iPod Touch built in

accelerometers.

Validatable, instant

comparisons of left and right.
