Background: Handgrip muscle strength test describes the of hand muscles used to grasp or grip. Currently, grip evaluation is often in clinical practice, as a marker function and disability. In fact, it has already been applied an outcome measure arthritis rheumatoid trials, demonstrate benefits several treatments [1]. However, disability should also be considered all other rheumatological disea...

While task-dependent changes in motor cortical outputs have been previously reported, the issue of whether such changes are specific for complex hand tasks remains unresolved. The aim of the present study was to determine whether cortical inhibitory tone and cortical output were greater during precision grip and power grip. Motor cortex excitability was undertaken by using the transcranial magn...

AIM The aim of the study was to investigate coordination of fingertip forces during an asymmetrical bimanual task in children with unilateral cerebral palsy (CP). METHOD Twelve participants (six males, six females; mean age 14y 4mo, SD 3.3y; range 9-20y;) with unilateral CP (eight right-sided, four left-sided) and 15 age-matched typically developing participants (five males, 10 females; mean ...

Eight patients with a traumatic unilateral upper limb amputation, who used conventional myoelectric prostheses, were also fitted with a commercially available myoelectric prosthetic hand with an adaptive grip, in order to compare the functional benefit of the two types of prostheses. Comparisons were made regarding width of grip, force of grip, scores in a standardised grip function test and pr...

KEY POINTS When standing and holding an earth-fixed object, galvanic vestibular stimulation (GVS) can evoke upper limb responses to maintain balance. In the present study, we determined how these responses are affected by grip context (no contact, light grip and firm grip), as well as how they are co-ordinated with the lower limbs to maintain balance. When GVS was applied during firm grip, hand...

BACKGROUND Several problems are associated with manual muscle testing and dynamometry in the hands of patients with Charcot-Marie-Tooth (CMT) disease. OBJECTIVE To evaluate the efficacy of the Rotterdam Intrinsic Hand Myometer (RIHM) to directly measure intrinsic hand muscle strength in CMT disease. METHODS We measured hand muscle strength and hand function in 41 patients with CMT disease. ...

The purpose of this study was to compare nondysfunctional children with and without handwriting difficulties for an examination of grip and hand preference. Additionally, in the group of children with handwriting difficulties, the children with decreased proprioceptive-kinesthetic finger awareness were compared with the children without such a decrease. The results suggest that children with ha...
