A finger goniometer measures range-of-motion (ROM) of finger joints (metacarpophalangeal and interphalangeal) and other small joints including toes. Unique design allows measurements to be taken by the therapist using only one hand; this frees up the therapist's other hand to stabilize the patient during measurement or to record the measurement; the standard finger goniometer requires two hands to make a finger ROM measurement. 6" stainless steel finger goniometer has head with opposing measures 110° flexion through 40° hyper-extension in 5° increments. Linear scale on arm measures in inches and centimeters and has 10cm / 4" scale.
