The commonest cause of radial nerve dysfunction is from extrinsic compressions of the radial nerve, such as against the shaft of the humerus in “Saturday night palsy”. However, this chapter focuses on the less common intrinsic compression neuropathies of the radial nerve. Intrinsic radial nerve compression neuropathies occur much less frequently than those of the median or ulnar nerves. The com...

In tetraplegia, hand reconstruction is of high priority. Key pinch has been advocated for tetraplegia because the lack donors nerve and tendon transfers. We report a patient with mid-cervical who underwent transfers in right left upper limbs seven months post-injury to reconstruct function. The particularity our case resides left-hand thumb index pulp-to-pulp reconstruction. For this, we transf...

The assessment of spasticity under voluntary movement is helpful for the therapist to comprehensively assess patient's dyskinesia. However, current researches focus on evaluation based passive motion. We propose a new method evaluating active Our following three steps: (i) Empirical Mode Decomposition (EMD) used reduce involuntary noise in patients' movement; (ii) Extract segments each muscle f...

BACKGROUND Peripheral nerve injury and brachial plexopathy are known, though rare complications of coronary artery surgery. The ulnar nerve is most frequently affected, whereas radial nerve lesions are much less common accounting for only 3% of such intraoperative injuries. CASE PRESENTATIONS Two 52- and 50-year-old men underwent coronary artery surgery. On the first postoperative day they bo...

OBJECTIVE Referred pain and pain characteristics evoked from the extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum communis, and brachioradialis muscles was investigated in 20 patients with lateral epicondylalgia (LE) and 20-matched controls. METHODS Both groups were examined for the presence of myofascial trigger points (TrPs) in a blinded fashion. The qualit...

Group I fibers from muscle spindles and Golgi tendon organs modulate motoneuron excitabilities to coordinate smooth movements. In this study, to elucidate the effects of group I fibers of the median nerve (MN) on the excitabilities of the brachioradialis (BR), we evaluated the changes in the firing probability of a BR motor unit after electrical conditioning stimulation (CS) to MN with a post-s...

PURPOSE To understand the mechanical properties of the brachioradialis (BR) muscle and to use this information to simulate a BR-to-flexor pollicis longus (FPL) tendon transfer for restoration of lateral pinch. METHODS The BR mechanical properties were measured intraoperatively. Passive elastic properties were measured by elongating BR muscles at constant velocity while they were attached dire...
