BACKGROUND The prevalence of upper-extremity musculoskeletal disorders, such as tendinitis, is elevated among dental practitioners. An important risk factor for these disorders is forceful pinching; however, the pinch forces and instrument forces during scaling are unknown. METHODS Six dentists and six senior-year dental students were recruited to use an instrumented periodontal scaler to per...
This cross-sectional study aimed to assess the impact of age and gender on 4 measures of grip and pinch force of well elderly community dwellers and to provide normative values. The hypotheses were that age and gender affect pinch and grip force and that these 2 factors might interact. Hand strength of 224 seniors 65-92 years old was tested. Grip and pinch force decreased in successively older ...

The purpose of this study was to establish normative data for 6- to 19-year-olds on four tests of hand strength. The Jamar dynamometer was used to measure grip strength and a pinch gauge was used to measure tip, key, and palmar pinch. A sample of 231 males and 240 females from the seven-county Milwaukee area was tested, using standardized positioning and instructions. Results of this study indi...
BACKGROUND Grip size of a tennis racquet has been reported to influence performance, but clear evidence of a correlation has yet to be established. HYPOTHESIS Hitting force during a soft tennis forehand stroke correlates with grip size. STUDY DESIGN Controlled clinical study. METHODS A total of 40 healthy volunteers (20 men and 20 women) with a mean age of 21.9 years were enrolled. Of the...
BACKGROUND Measuring grip and pinch strength is an important part of hand injury evaluation. Currently, there are no standardized values of normal grip and pinch strength among the Korean population, and lack of such data prevents objective evaluation of post-surgical recovery in strength. This study was designed to establish the normal values of grip and pinch strength among the healthy Korean...
This study was designed to establish norms of hand function, and to identify developmental characteristics of hand function among the Korean children. 712 elementary school children participated in measurement of grip strength, three kinds of pinch strength, and dexterity. The hand strength of the Korean children appeared to be weaker than that of western children. The grip strength of boys was...
Droplet formation in a flow focusing microfluidic device was studied for capillary numbers between 10−4 and 10−1. The addition of cationic surfactant to the dispersed phase effect continuous viscosity on droplet size, neck kinetics fields inside drop investigated. size decreased with an increase number following power law exponent dependent confinement. At 1–3 ms before pinch-off, thinning rate...
Carpal tunnel syndrome (CTS) is a neuropathy due to the compression of the median nerve. It is shown that gabapentin in high doses is effective in treatment of CTS patients. In this study we evaluated the efficacy of low doses of gabapentin in treatment of CTS patients. Ninety patients with CTS were randomly assigned to groups A, B and C. Gabapentin was administered to group A with dose of 100 ...
A linear pinch discharge above the Pease-Braginskii current and stabilized by axial shear flow can radiatively collapse to high densities. A thermonuclear detonation wave can then be launched from one end of the discharge channel by ignition with a powerful laser pulse. Axial shear flow stabilization may be realized by injecting a fast moving jet along the pinch discharge channel, possibly in c...
