5) Finger Pinch Strength (FPS): The pinch strength was tested using a pinch meter
(Jamar[R] Pinch Gauge, TEC, Clifton, New Jersey, USA).
Grip and pinch strength were measured using the Jamar dynamometer (E-Link, Biometrics Ltd; Newport, United Kingdom) in five positions and the pinch meter as advocated by the American Society of Hand Therapists [3-4].
Function scores over time (T0-T4) for i-LIMB and i-LIMB Pulse hands: grip strength and pinch strength measured with Jamar dynamometer and pinch meter, respectively; Southampton Hand Assessment Procedure (SHAP); SHAP Index of Function (IoF) scores; and log-odds scores of Assessment of Capacity for Myoelectric Control 2.0 (ACMC).
Using a simple pinch meter
, Soares and Riedel (13) found that, compared to normal subjects, the pressure exerted by hands of leprosy patients showed a reduction in strength of up to 49%.
A pinch meter
will be used to measure pinch strength in the fingers laterally, tip-to-tip, and palmar (Jamar Pinch Gauge, 0-45 lb., Sammons Preston Inc., Bolingbrook, IL).
