OBJECTIVE This study examined the effect of commonly used long and short styles of commercially produced wrist extension orthoses on the activity of the proximal muscles of the shoulder and elbow and on wrist flexor and extensor muscle activity. METHOD While 17 women between 22 and 40 years of age (M = 26.6) performed a specified movement wearing each of the two styles of orthosis and without...

Purpose: The purpose of this study is to investigate the relationship between myoelectric activities of wrist flexors and extensors and hand grip strength at four different positions of shoulder and elbow joints. Subjects: Thirteen normal male university students volunteered to participate in this study. Their mean ages, weights and heights were 19.6 (± 1.06) years, 75.9 (± 7.51) Kg and 173.5 (...

27 The human motor cortex is capable of rapid and long-lasting reorganization. This 28 reorganization is evident globally, in the form of shifts in body part representations, and at 29 the level of individual muscles in the form of changes in corticospinal excitability. 30 Representational shifts provide an overview of how various body parts reorganize relative to 31 each other but do not tell ...

Two raters performed hand-held dynamometer testing of six muscle groups of 30 patients to determine the interrater reliability of the procedure. The six muscle groups tested were the shoulder external rotators, elbow flexors, wrist extensors, hip flexors, knee extensors, and ankle dorsiflexors. The patients were of eight different diagnostic groups, with most having hemiparesis secondary to cer...

Human motor cortex is capable of rapid and long-lasting reorganization, evident globally, as shifts in body part representations, and at the level of individual muscles as changes in corticospinal excitability. Representational shifts provide an overview of how various body parts reorganize relative to each other but do not tell us whether all muscles in a given body part reorganize in the same...

When moving objects with a precision grip, fingertip forces normal to the object surface (grip force) change in parallel with forces tangential to the object (load force). We investigated whether voluntary wrist actions can affect grip force independent of load force, because the extrinsic finger muscles cross the wrist. Grip force increased with wrist angular speed during wrist motion in the h...

QUESTIONS In adults undergoing rehabilitation after stroke, does 30 minutes of daily stretch of the wrist and finger flexors for four weeks prevent or reverse contracture, decrease pain, or improve upper-limb activity? Are any gains maintained one week and five weeks after the cessation of stretching? DESIGN Randomised controlled trial with concealed randomisation, assessor blinding, and inte...

Motor function in type 2 diabetes is largely unknown. In 36 type 2 diabetic patients and in 36 control subjects matched for sex, age, weight, height, and physical activity, strength of flexors and extensors at elbow, wrist, knee, and ankle was assessed at isokinetic dynamometry. The degree of neuropathy was determined by clinical scores, nerve conduction studies, and quantitative sensory testin...

BACKGROUND Loss of elbow flexion due to traumatic palsy of the brachial plexus represents a major functional handicap.Then, the first goal in the treatment of the flail arm is to restore the elbow flexion by primary direct nerve surgery or secondary reconstructive surgery. There are various methods to restore elbow flexion which are well documented in the medical literature but the most known a...
