[Purpose] This study verified the changes in muscle activities and grasping power during maximal isometric exercise of the forearm and masseter muscle with and without a mandibular orthopedic repositioning appliance (MORA). It also offers basic data for defining the correlation of function of hand with mouth. [Methods] EMG was used to measure masticatory muscle, flexor bundle and extensor bundl...

The purpose of this study is twofold: (1) to describe the hand strength, self-reported manual ability and health status in individuals with osteo- or rheumatoid arthritis, and (2) to evaluate the scale (psychometric) properties of the 36-item Manual Ability Measure (MAM) as it applied to this sample. We administered four self-report assessments to the participants and measured their grip and pi...

Elevated carpal tunnel pressure (CTP) has been associated with carpal tunnel syndrome. This study systematically evaluated the effect of wrist motion resistance and grip type on CTP during wrist motion typical of occupational tasks. CTP during four wrist motion patterns, with and without resistance, and with and without gripping, was measured in vivo in 14 healthy individuals. CTP measured duri...

BACKGROUND Aging is accompanied by a marked decline in muscle strength and ability to maintain steady submaximal force. Studies have shown that exercise programs can improve age-related regression of hand function in elderly individuals. The purpose of this study was to train elderly subjects to perform skilled finger movements and to evaluate the changes in hand function involving skillful use...

Repetitive use of hand tools (particularly those that compress the palm of the hand and are held with a pinch or precision grip) may result in the development of carpal tunnel syndrome and other musculoskeletal disorders of the hand, wrist, and arm. Workers in the screen-printing industry use wooden-handled squeegees to force ink through a screen and into a substrate. The industry standard hand...

BACKGROUND Objective assessment of motor function is frequently used to evaluate outcome after surgical treatment of carpal tunnel syndrome (CTS). However a range of outcome measures are used and there appears to be no consensus on which measure of motor function effectively captures change. The purpose of this systematic review was to identify the methods used to assess motor function in rando...

OBJECTIVE To assess the relationship between muscle strength (Jama), and pain (VAS) levels with hand function (DASH) in patients with trapeziometarcapal osteoarthritis. Cross-sectional study. PARTICIPANTS Sample of 72 patients with osteoarthritis stage 2-3 (Eaton) and trapeziometacarpal osteoarthritis. Patients were recruited when they came to the Hand Surgery Unit. METHOD Grip strength, pi...
