Grip and pinch strength are important for everyday functional tasks such as holding utensils and unlocking a door with a key. Grip strength is measured using a dynamometer and pinch strength is measured using a pinch meter gauge.
Testing Procedures:
For each grip and pinch strength measurement, take three measurements with a break in between. Take the average of these numbers and compare to the chart of norms. For each measurements, tell the client to pinch/grip as hard as they can.
Grip Strength
Testing Position:
Client flexes elbow to 90 degrees and holds hand in neutral position. Therapist may stabilize the dynamometer while the client squeezes.
Norms:
Pinch Strength - Two Point Pinch (Tip to Tip)
Testing Position:
Client's hand is in pronation and places index finger on top of pinch gauge and thumb below. Therapist stabilizes the other end of the gauge.
Norms:
Pinch Strength - Three Point Pinch (Palmer, Three Jaw Chuck)
Testing Position:
Client's hand is in pronation and places index and middle fingers on top of pinch gauge and thumb below. Therapist stabilizes the other end of the gauge.
Norms:
Pinch Strength - Lateral Pinch (Key Pinch)
