Scales on grip and pinch dynamometers are covered prior to measuring matching grip and pinch forces.
Workers' dominant handgrip, lateral pinch and 3-point pinch strengths are measured using grip and pinch dynamometers (3 trials for each measurement) (Additional file 2).
Gross grip strength and key and palmar pinch strength were obtained bilaterally using digital grip and pinch dynamometers (JTech Medical, Salt Lake City, UT) (Mathiowetz et al. 1984).
As a result, regular instruments for measuring hand function, such as grip and pinch dynamometers, measure a combination of muscle groups and joints.
Using a scale and a pinch grip dynamometer, the examiners practiced a finger-pressure (thumb, index finger, and middle finger, respectively) and pinch grip (i.e. pressing the thumb against the index finger) of 2 kg - a procedure which was repeated frequently between examinations during the study period.
The hypothetical risks of placing a constraint for 6 h each day on the less affected extremity will be addressed as follows: prior to encouraging the continued wear of the long mitt each week, both the more and the less affected extremity will be tested for grip and pinch using dynamometers and five repeated assessments in each hand.
There was no effect of treatment on hand function: hand grip (Jaymar dynamometer); pinch strength; coordination (Hole Peg test, Preston Grooved Pegboard test).
Each person had to undergo grip strength testing using a Jamar dynamometer and key pinch testing using a pinch gauge.
For the assessment of the upper limb impairments, we used 9-hole peg test, dynamometers for pinch and grasp forces, and Upper Limb Fugl-Meyer Scale.
Assessment equipment (Jamar Dynamometer and B&L Pinch Gauge [ 33]) will be calibrated prior to the start of the study.
Participants will also be asked to complete a test of maximal gross grip strength using a Jamar dynamometer (Sammons Preston, Chicago, IL) and pinch grip strength using a B&L pinch gauge (B&L Engineering, Tustin, CA).
