Definition[edit | edit source]
The pinch grip is a form of precision grip where by an object is pinched between the palmar surface of the fingers and the opposing thumb. The pinch grip is also then categorised into five groups. [1]
Purpose[edit | edit source]
The Pinch grip test is used to examine the neurological dysfunction of the anterior interosseous nerve branch of the median nerve [2] .
Median Nerve Innervation[edit | edit source]
The median nerve originates from the lateral and medial cords of the brachial plexus (C5-T1). During the pinch movement, the median nerve supplies digits 2 and 3 extrinsic flexion to the thumb; the motor branch supplying flexor digitorum superficialis while the anterior interosseus branch innervates the flexor pollicis longus and flexor digitorum profundus muscles. The median nerve is the most involved in innervations of pinch and fine precision functions of the hand [3].
Technique[edit | edit source]
Step1. Ask the patient to pinch the tip of the index finger and tip of the thumb.
Step2. If the patient unable to pinch tip to tip with both fingers and instead as using an abnormal pad to pad pinch of the index and thumb.
Step3. This is a positive sign of pathology to the anterior interosseous nerve, which is a branch of the median nerve.[4]
Interpretation of Results[edit | edit source]
A Positive sign is seen when there is an inability to pinch tip to tip.
