PURPOSE This study aimed to evaluate the kinematics of the flexor pollicis longus tendon (FPL) at the wrist by examining the movement of the FPL on the distal radius during various wrist and finger motions using transverse ultrasound in healthy volunteers. METHODS Forty-eight wrists of 24 asymptomatic volunteers were examined by transverse ultrasound to observe the location of the FPL on the ...

Septic arthritis of the wrist is rare entity, especially; atypical mycobacterial infection of the wrist is extremely rare. We report a case of septic arthritis of the wrist caused by Mycobacterium intracellulare, which was successfully treated by radical debridement followed by wrist arthrodesis using vascularised fibular grafting.

OBJECTIVE To investigate the correlation of the ultrasonographic wrist-to-forearm median nerve area ratio (WFR) and cross sectional area of median nerve at the wrist (CSA-W) to the electrophysiologic severity in patients with carpal tunnel syndrome (CTS). METHOD One hundred and ten wrists electrophysiologically graded as mild, moderate, and severe CTS and 38 healthy controls underwent ultraso...

This study examined the relationship between fractional anisotropy (FA) values of magnetic resonance-diffusion tensor imaging (DTI) and motor outcome (1 month after onset) in 15 patients with hemiparesis after ischemic stroke of corona radiata lesions. DTI data were obtained on days 14-18. FA values within the cerebral peduncle were analyzed using a computer-automated method. Motor outcome of h...

AIM To develop classification criteria for Chinese pulse diagnosis and to objectify the ancient diagnostic technique. METHODS Chinese pulse curves are treated as wave signals. Multidimensional variable analysis is performed to provide the best curve fit between the recorded Chinese pulse waveforms and the collective Gamma density functions. RESULTS Chinese pulses can be recognized quantitat...

Electromyography (EMG) has been widely used for the assessment of musculoskeletal functions and the control of electrical prostheses, which make use of the EMG signal generated by the contraction of the residual muscles. In spite of the successful applications of EMG in different fields, it has some inherent limitations, such as the difficulty to differentiate the actions of neighboring muscles...

Magnetic resonance imaging (MRI) and MR arthrography are both effective means to evaluate the instrinsic and extrinsic ligaments of the wrist, as well as the triangular fibrocartilage (TFC) [1-6]. High resolution detail of the wrist can be achieved with a variety of magnet strengths, with 1.5 Tesla (T) and 3T being the most commonly utilized in current practice. Dedicated wrist coils are critic...

It is necessary to detect complex force and torque components of three-dimensional space in research and manufacture, therefore the multi-axis force and torque sensors are developed rapidly. For examples, the six-axis wrist force/torque sensor for robot assembling and automated polishing [1,2], the multi-component strain gauge balance for wind tunnel testing to determine loads on models [3], th...

We used our voluntary rat model of reaching and grasping to study the effect of performing a high-repetition and high-force (HRHF) task for 12 weeks on wrist joints. We also studied the effectiveness of ibuprofen, administered in the last 8 weeks, in attenuating HRHF-induced changes in these joints. With HRHF task performance, ED1+ and COX2+ cells were present in subchondral radius, carpal bone...
