BACKGROUND: One of the characteristics of parkinsonian tremor is that its amplitude decreases with movement. Current models suggest an interaction between basal ganglia (BG) and cerebello-thalamo-cortical circuits in parkinsonian tremor pathophysiology. OBJECTIVE: We aimed to correlate central oscillation in the BG with electromyographic activity during re-emergent tremor in order to detect changes in BG oscillatory activity when tremor is attenuated by movement...

BACKGROUND: Ganglion cysts are the most common soft tissue mass in the hand and wrist in both adults and children. More is known about wrist ganglia and their treatment outcomes in adults than in children. Current literature to guide the management of pediatric wrist ganglia is limited. The purpose of this study is to report on the rates of recurrence of pediatric wrist ganglia after active intervention-aspiration or surgical excision-at a single center, as well as to explore factors associated with recurrence in one of the largest samples to date of pediatric wrist ganglia...

Background  Synovial cysts (SCs) are the most frequent wrist tumors; the arthroscopic treatment presents good results when surgery is indicated for symptomatic or patients with cosmetic concerns. The tumoral lesion should be arthroscopically decompressed or drained toward the inside of the joint through pedicle opening and resection of a small portion of the capsule. Hence, the cyst pedicle must be found for the success of this technique. Description of Technique  Some tricks have already been described to facilitate SC location during arthroscopy...

Primary carnitine deficiency (PCD) is caused by pathogenic variants of the SLC22A5 gene, which encodes a transmembrane protein that functions as a high affinity carnitine transporter. Carnitine is essential for the transport of acyl-CoA, produced from fatty acids, into the mitochondria where they are oxidised to produce energy. We present the case history of an 8-year-old boy who presented with fever, lethargy, focal rhythmic (3 Hz) left wrist twitching, and severe encephalopathy. MRI brain showed basal ganglia involvement...

INTRODUCTION: We and others have shown that electrical stimulation of the PC-6 acupoint over the wrist relieves hypertension by stimulating afferent sensory nerve fibers and activating the central endogenous opioid system. Warm needle acupuncture has long been utilized to treat various diseases in clinics. METHODS: Here, we developed a temperature-controllable warm needle acupuncture instrument (WAI) and investigated the peripheral mechanism underlying the effect of warm needle acupuncture at PC-6 on hypertension in a rat model of immobilization stress-induced hypertension...

This pilot study assessed the feasibility of performing a randomized control trial (RCT) investigating injection with platelet-rich plasma (PRP) for dorsal wrist ganglion (DWG). Aspiration alone was compared with aspiration plus injection of PRP. Seventeen patients were enrolled. Nine patients received PRP and eight aspiration alone. Patients were followed up at 6 weeks and 1 year; recurrence of the ganglion and Patient Evaluation Measure scores were measured. At 6 weeks seven patients in the aspiration group had a recurrence and five in the PRP group, but by 1 year, this has increased to seven out of eight in the PRP group whereas in the aspiration group four had resolved leaving three out of eight patients with a ganglion still present...

Tremor is thought to be an effect of oscillatory activity within the sensorimotor network. To date, the underlying pathological brain networks are not fully understood. Disentangling tremor activity from voluntary motor output and sensorimotor feedback systems is challenging. To better understand the intrinsic sensorimotor fingerprint underlying tremor, we aimed to disentangle the sensorimotor system into driving (motor) and feedback/compensatory (sensory) neuronal involvement, and aimed to pinpoint tremor activity in essential tremor (ET) and tremor-dominant Parkinson's disease (PD) with a novel closed-loop approach...

We compared arthroscopic cyst resection (ACR) of dorsal ganglia of the wrist, either associated to reconstruction of the dorsal capsuloligamentous scapholunate septum (ACR-DCSS) in 66 cases in which the ganglia were painful on exertion, or isolated ACR in 15 pain-free cases. A single-center retrospective study analyzed data for the period April 2013 to May 2021. The main aim was to compare pre- and post-operative functional results (pain at rest (on a numerical rating scale: NRS), pain under effort (NRS), range of motion (°), grip strength (kg)) and recurrence rate between the two techniques...

Intraosseous lunate bone ganglia (ILBG) are known to be a cause of chronic wrist pain and disability. Standard treatment consists of curettage and autologous bone grafting. Open procedures have shown good results with few recurrences, but with frequent stiffness or persistent pain. Arthroscopic techniques are more recent and seem very reliable. Several arthroscopic techniques have been reported for ILBG approach and treatment. The present study describes an approach that preserves all the lunate cartilage of both radiocarpal and midcarpal surfaces...

BACKGROUND: Dorsal ganglia are the most common types of wrist ganglia. Though largely asymptomatic, they can cause pain, stiffness and require treatment. The different methods described for the management have high recurrence rates even up to 70%. We describe a new method which combines 3 of these methods thus aiming to achieve the best from each of the techniques. METHODS: A prospective observational study was undertaken to include patients requiring surgery for dorsal ganglion...

INTRODUCTION: Hyperhidrosis is the maladjustment of excess sweating in specific parts of the body. Radiofrequency (RF) therapy has been successfully used to treat hyperhidrosis with a success rate of 85% - 95% in patients refractory to sympathectomy. The main hypothesis was the association between reduced palmar hyperhidrosis and radiofrequency RF therapy. The RF therapy is a less invasive technique, including the utilization of electromagnetic energy that is deposited near the nerve tissue...

RATIONALE: Wrist-hand extension function rehabilitation is a vital and difficult part of hand function recovery in spastic stroke patients. Although botulinum toxin type A (BoNTA) injection plus post injection therapy was applied to the wrist-hand rehabilitation in previous reports, conclusion was inconsistent in promoting function. For this phenomenon, proper selection of patients for BoNTA injection and correct choice of post-injection intervention could be the crucial factors for the function recovery...

Dystonia is a disorder of sensorimotor integration associated with abnormal oscillatory activity within the basal ganglia-thalamo-cortical networks. Event-related changes in spectral EEG activity reflect cortical processing but are sparsely investigated in relation to sensorimotor processing in dystonia. This study investigates modulation of sensorimotor cortex EEG activity in response to a proprioceptive stimulus in children with dystonia and dystonic cerebral palsy (CP). Proprioceptive stimuli, comprising brief stretches of the wrist flexors, were delivered via a robotic wrist interface to 30 young people with dystonia (20 isolated genetic/idiopathic and 10 dystonic CP) and 22 controls (mean age 12...
