The contribution of the intrinsic muscles to grip and pinch strength

The Journal of Hand Surgery, 1999
Profound deficiencies occur in the intrinsic minus hand with loss of the interossei, thenar, hypothenar, and adductor pollicis muscles. The purpose of this study was to define the load-generating deficiencies of grip and pinch after simulated low median and/or low ulnar nerve lesions.

The effects of pinch width on pinch strengths of adult males using realistic pinch-handle coupling

International Journal of Industrial Ergonomics, 1995
Abstract This study examined the effects of pinch width on pinch strengths, using more realistic pinching conditions — larger contact area, worktable height pinching level, and freedom to hyperextend the thumb when gripping. Chuck, pulp-2 and lateral pinches were tested at widths within the range of 2.0–14.0 cm among 17 right-handed male volunteers ...

EVALUATING THE EFFECTS OF SPLINT, PINCH TYPE, AND WRIST POSTURE ON PINCH STRENGTH

Journal of the Chinese Institute of Industrial Engineers, 2003
ABSTRACT Pinch strength applied in repetitive tasks was considered to be highly correlated with cumulative trauma disorders (CTDs). To reduce the magnitude requirement of pinch strength is important to avoid such injuries. But whether the peak pinch strength was affected by wearing wrist splints, sometimes used to protect the wrist from CTDs, is still ...

Measurement of maximum voluntary pinch strength:

Journal of Hand Therapy, 2003
Abstract The purpose of this study was to determine the effects of forearm position and outcome score on key, fingertip, and three-jaw chuck pinch strength. Maximum voluntary key, fingertip, and three-jaw chuck pinches were performed by 135 healthy adults (20–88 years old) three times in a pronated, supinated, and neutral forearm position with the ...

Grip and Pinch Strength Variations in Different Types of Workers

Journal of Hand Surgery, 1997
We measured grip and pinch strengths in non-manual, light manual and heavy manual workers using a Jamar dynamometer and a pinch measuring device. Heavy manual workers had the strongest grips with the least difference between sides. Office workers had the weakest grips and the greatest difference between sides.

The strength–dexterity test as a measure of dynamic pinch performance

Journal of Biomechanics, 2003
We have developed a method to quantify the dynamic interaction between fingertip force magnitude (strength) and directional control (dexterity) during pinch with a novel strength-dexterity (S-D) test based on the principle of buckling of compression springs.

Effect of elbow position on grip and key pinch strength

The Journal of Hand Surgery, 1985
Twenty-nine college women participated in a study to investigate the effect of elbow position on grip and key pinch strength evaluations. Standardized instructions and positioning were followed with the exception of the two elbow positions. The elbow was flexed to 90 degrees in one test condition and it was fully extended in the other.

The effects of gloves on grip strength and three-point pinch

Journal of Hand Therapy, 2001
No-glove, leather-glove, nitrile-glove, and vinyl-glove conditions were evaluated to determine their effects on grip strength and three-point pinch. Forty-one adult volunteers from a local university and local hospital participated in the two-day study. The order of testing was randomly assigned. A hydraulic hand dynamometer and a hydraulic pinch gauge

Fluctuation in grip and pinch strength among normal subjects

The Journal of Hand Surgery, 1989
Grip and pinch strength testing are commonly used to evaluate hand strength for disability ratings and to assess responses to various forms of therapy. This study determined the variations in grip and pinch strength in normal individuals. Ninety-five healthy subjects--61 women and 34 men--were examined prospectively by use of a Jamar dynamometer and a ...

Measurement of thumb abduction strength: Normative data and a comparison with grip and pinch strength

The Journal of Hand Surgery, 1997
Abduction strength of the thumb was measured in normal men (n = 101; age range, 21-94 years) and women (n = 208; age range, 20-97 years). Abduction-strength measurements were conducted concurrently with grip and pinch strength measurements made by well-established clinical methods. Normal values were established and stratified by age and sex.
