Filter by:Traumatic brachial plexus lesions may lead to permanent impairment of hand function despite brachial plexus surgery. In selected cases the affected forearm can be amputated and replaced by a bionic hand. It is unclear how cortical activation patterns change after the injury and after acquisition of the hand prosthesis considering the complex changes in sensory and motor feedback. The aim of the study is to measure cortical activity with fMRI during actual and imagery movements with the affected and healthy arm in a group of patients after traumatic brachial plexus injury and a group in whom this was followed by replacement with a bionic hand. In this prospective study three groups of patients will participate: 1) 3 adult patients with a traumatic brachial plexus lesion eligible for a bionic arm but prior to its acquisition, 2) 3 patients with a traumatic brachial plexus lesion who have acquired the bionic arm already, and 3) 10 healthy subjects. The investigators will measure cortical activity using fMRI BOLD tasks of closing the hand and motor imagery of this movement. Cortical activity will be compared between the three groups. Additionally, regional gray matter volume, resting-state, and DTI networks will be studied. Written informed consent will be provided prior to the investigation. The complete examination has a duration of approximately 45 minutes.
To determine the role of using Kinesiology tape on the prevention of elbow flexion tightness in infants with extended Erb's palsy.
The investigators seek to evaluate the effectiveness of Armeo®Spring Pediatric training, as compared to conventional treatment, in improving upper extremity function in children with Narakas I brachial plexus injury, aged 5-8 years, using the Mallet modified scale and passive range of movement, immediately post intervention and at 3 and 6 months´ follow up. The investigators will also monitor the appearance of adverse effects during and post intervention, with a follow up at 3 and 6 months.
Radiation-induced brachial plexopathy (RIP) is a rare and severe delayed peripheral nerve complication of radiotherapy, that is spontaneously irreversible with no medical treatment to limit or reduce symptoms. The investigators planed in RIP a randomized double blind clinical trial, using a pentoxifylline (P)- tocopherol (E)- clodronate combination versus placebo, to assess a possible symptomatic regression by a sensory-motor neurological quantifiable and reproducible score (modified Subjective Objective Medical management Analytic, SOMA). The investigators previously developed a successful PE treatment in symptomatic RI injuries via the antioxidant pathway, in clinical phase II and III trails and experiments obtaining a major significant radiation-induced fibrosis regression, then the PE clodronate combination (PENTOCLO), obtaining a rapid and significant healing of mandible osteoradionecrosis and significant neurological signs regression (- 35% modified SOMA score at 18 months) in 50 partial RIP. The aim of this phase III randomized clinical trial is to show PENTOCLO efficiency and its tolerance in long survival patients irradiated before for cancer and presenting with partial RIP of upper or lower legs. The investigators calculated to include 60 patients to show a significant clinical difference between the two groups after 18 months of treatment: PENTOCLO[Pentoxifylline 400 (2x/d) + vitamine E 500 (2x/d) + intermittent Clodronate 800 (2/d, 5d/7)] versus triple placebo, with prednisone 20 (2d/7) for all patients. RIP is assessed before treatment and every 6 months by a standardized sensory-motor neurological (SOMA 95 modified by NCI-CTC 99) score used for main criteria at M18, and various neurological scales of assessment (Visual Analog Scale for pain / VAS for paresthesia, Neuropathic Pain Symptom Inventory [NPSI], Overall Disability Sum Score [ODSS], muscle testing, Nine hole peg test / Timed 25-Foot Walk), quality of life (SF36, Patient Global Impression of Change and Clinical Global impression of Change [PGIC/ CGIC]) and electrophysiology.
