Elevated carpal tunnel pressure (CTP) has been associated with carpal tunnel syndrome. This study systematically evaluated the effect of wrist motion resistance and grip type on CTP during wrist motion typical of occupational tasks. CTP during four wrist motion patterns, with and without resistance, and with and without gripping, was measured in vivo in 14 healthy individuals. CTP measured duri...

Primary care physicians not only have an important role in the diagnosis and initial treatment of wrist injuries, but also play a key role in the education of families about prevention. Children and adolescents are often competitive in sports throughout the year. Periods of rest can be important in prevention of overuse injuries in the very active, developing athlete. Protective gear such as wr...

OBJECTIVE To evaluate the activity of wrist extensor muscle, correlating with wrist motion during gripping after flexor tendon repair. DESIGN Cross-sectional clinical measurement study. SETTING Laboratory for biomechanics and rehabilitation. SUBJECTS A total of 11 patients submitted to rehabilitation by early passive motion of the fingers with wrist flexion position were evaluated after 8...

Diagnosis of upper extremity injuries depends on knowledge of basic anatomy and biomechanics of the hand and wrist. The wrist is composed of two rows of carpal bones. Flexor and extensor tendons cross the wrist to allow function of the hand and digits. The ulnar, median, and radial nerves provide innervation of the hand and wrist. A systematic primary and secondary examination of the hand and w...

• The luminosities of the quasars with the largest redshifts indicate that central BH masses of > 10 M⊙ were already present when the Universe was less than 10 years old (Barth et al. 2003). These masses are lower limits as they are based on the assumption that the BHs accrete at their Eddington limit. There is no indication that the (majority of the) sample of highest-redshift-quasar luminosit...

abstract background: radiography is the most widely available imaging modality. precise evaluations of wrist x-ray can help diagnosis and evaluate the prognosis of many wrist disorders. methods: we measured length, angles and indices in 150 posteroanterior and lateral wrist x-rays to determine normal dimensions and variations according to age and sex. all x-rays were made with standard exposure...

CONTEXT Regaining full, active range of motion (AROM) after trauma to the wrist is difficult. OBJECTIVE To report the cases of 6 patients who lacked full range of motion (ROM) in the wrist due to trauma. The treatment regimen was thermal 3-MHz ultrasound and joint mobilizations. DESIGN Case series. SETTING University therapeutic modalities laboratory. PATIENTS OR OTHER PARTICIPANTS Six ...

Recent data from this laboratory on differential controls for the shoulder, elbow, and wrist exerted by the thalamo-cortical network during locomotion is presented, based on experiments involving chronically instrumented cats walking on a flat surface and along a horizontal ladder. The activity of the following three groups of neurons is characterized: (1) neurons of the motor cortex that proje...

Tenodesis refers to opposition of the thumb and index finger with either active or passive wrist extension. Achieving a functional tenodesis grasp is a primary focus of therapy for such a person, to enable participation in activities of daily living. Tenodesis grasp is achieved with people who have a complete C6 level of quadriplegia, using a range of clinical interventions: passive wrist and h...
