Treatment of carpal tunnel syndrome (CTS) remains a challenge for hand surgeons. Carpal tunnel release (CTR) using nasal instruments has the advantages of both endoscopy and open surgery. In this study we aimed to explore the effectiveness of CTR using nasal instruments in Chinese patients.We present a case series of 49 cases of idiopathic CTS treated with the mini-incision technique using nasa...

OBJECTIVE To evaluate the results of 4 mg of dexamethasone acetate injections for the treatment of carpal tunnel syndrome in pregnancy. MATERIAL AND METHOD Twenty-four pregnant volunteers who suffered from carpal tunnel syndrome occurring in the third trimester of their pregnancies were injected with 4 mg of dexamethasone acetate combined with 1% lidocaine into the carpal tunnels. The volunte...

AIM Mini incision techniques for carpal tunnel release have become increasingly popular for the treatment of carpal tunnel syndrome. The main advantages of mini incision techniques are shorter recovery and return-to-work time. However, the risk of neurovascular injury still remains worrisome. We present a novel method to release the carpal tunnel by using nasal instruments. This novel technique...

Hand motor impairment persists after stroke. Sensory inputs may facilitate recovery of motor function. This pilot study tested the effectiveness of tactile sensory noise in improving hand motor function in chronic stroke survivors with tactile sensory deficits, using a repeated measures design. Sensory noise in the form of subthreshold, white noise, mechanical vibration was applied to the wrist...

Ten cases of complete rupture of the collateral ligaments of the metacarpophalangeal finger joints are reported. The nature of this injury, the pre-operative morbidity and the intra-operative pathology are analysed. In all cases surgery was performed with satisfactory results. Operation is indicated for joint stability, grip and pinch strength, pain control and early functional recovery.

Developmental improvements in dynamic manipulation abilities are typically attributed to neural maturation, such as myelination of corticospinal pathways, neuronal pruning, and synaptogenesis. However the contributions from changes in the peripheral motor system are less well understood. Here we investigated whether there are developmental changes in muscle activation-contraction dynamics and w...

The formation of thick borders on an initially stationary two-dimensional fluid sheet surrounded by another fluid is examined by numerical simulations. The process is controlled by the density and the viscosity ratios, and the Ohnesorge number @Oh5m/(rds)# . The main focus here is on the variation with Oh. The edge of the sheet is pulled back into the sheet due to the surface tension and a thic...

We analyze ill-defined pinch singularities characteristic of out of equilibrium thermal field theories. We identify two mechanisms that eliminate pinching even at the single selfenergy insertion approximation to the propagator: the first is based on the vanishing of phase space at the singular point (threshold effect). It is effective in QED with a massive electron and a massless photon. In mas...

BACKGROUND Although grip and pinch strength provide a more global measure of a large number of digits and muscles, measuring strength of individual fingers or the thumb can provide additional and more detailed information regarding hand strength. QUESTIONS/PURPOSES We developed growth diagrams for individual finger strength in children. PATIENTS AND METHODS We measured thumb palmar abductio...

BACKGROUND Although there are several studies of systemic corticosteroid therapies in various doses and various durations in complex regional pain syndrome (CRPS), the outcome measurement parameters are limited to the range of motion measurements, edema, and symptoms of CRPS. OBJECTIVE To investigate the effects of prednisolone on clinical symptoms, pain, hand grip strength, range of motion, ...
