- B&L pinch gauge
- Paper, pen/pencil (to record scores)
- Have client seated comfortably, facing OT, with shoulder adducted, and elbow flexed to 90 degrees (parallel to ground).
- Show client which of the three pinch grips to do first (refer to images below):
- Tip-pinch – thumb and index fingers.
- Lateral/Key pinch – thumb pad and lateral aspect of index finger.
- Palmar pinch/3-Jaw Chuck – thumb, index, and middle fingers.
- Hold onto distal portion of B&L pinch gauge to help the client maintain steadiness.
- Have client perform one of the pinch grips above with three successive trials for each hand.
- Make sure to give client a few minutes rest in between trials to ensure accuracy.
- Record score for pinch strength after each trial.
- Score is the average of the three trials.
- After first pinch grip test is done, proceed onto the other two, following the same directions mentioned above.
- Record the average of the three trials for each hand, and also for each pinch position. Compare the standard to averages using the charts above.
- “3-jaw chuck grip strength = 25. Ct. is WNL.”
