Effects of exercise on carpal tunnel syndrome symptoms.

This is a study of whether participation in an exercise programme for increasing upper extremity flexibility, strength, and circulation has any effects on symptoms of carpal tunnel syndrome (CTS). Two groups (exercise and control) of seven participants each who did repetitive hand motion tasks were studied. The exercise group participated in daily arm, hand, and other upper-extremity exercises for 8 weeks. The control group did not participate in the exercise programme. Dependent (response) variables monitored were motor nerve conduction latency through the carpal tunnel, grip strength, and subjective comfort in the dominant hands of participants. Test results indicated no statistically significant differences in nerve conduction latency or subjective comfort between the two groups. Significant differences did develop in grip strengths over time, suggesting that the exercise group may have benefited physiologically from the exercise programme.

The effects of biofeedback on carpal tunnel syndrome.

Behaviour modification based on audible electromyographic (EMG) biofeedback signals was used to discourage the awkward hand postures and the exertion of excessive force with the fingers, which are suspected of causing carpal tunnel syndrome (CTS). The null hypothesis was that participation in such a biofeedback programme has no effect on CTS symptoms. Before and during an 8-week study, data were collected from two groups of five female assembly line workers each. The biofeedback group received training and input, while the control group did not. Test results indicated that the null hypothesis could not be rejected.

Thermography in the detection of carpal tunnel syndrome and other compressive neuropathies.

Studies were conducted using liquid crystal thermography (FlexiTherm) and electronic thermography for the diagnosis of carpal tunnel syndrome. Studies were also conducted to differentiate carpal tunnel syndrome from peripheral neurovascular injuries. Ninety patients were included in the study, with an average follow-up time of 24 months. Fifty patients also had electric studies for comparison and contrast. Thermal patterns of carpal tunnel syndrome showed a decreased vascular heat emission pattern over the median nerve distribution. The procedures using thermography consisted of imaging of the cervical spine, shoulders, forearms, and hands by Wexlerian guidelines to obtain diagnostic thermograms and a stress series. Results of the studies showed that thermographic studies were efficacious and sensitive for the differential diagnosis of carpal tunnel syndrome from other peripheral compressive neuropathies, including cervical radiculitis, thoracic outlet syndrome, cubital tunnel syndrome, and Guyon's canal syndrome. Biomechanic and etiologic factors indict carpal tunnel syndrome to be an occupational disease. Thermographic technique use may lead to the early diagnosis, treatment, and preventative measures that could eliminate the high cost of manpower loss and of medical care often concomitant with carpal tunnel syndrome.

Lipofibromatous hamartoma of the radial nerve: a case report.

Lipofibromatous hamartomas of the radial nerve are exceedingly rare. What is believed to be only the second such reported case is described, and a review of the pertinent histological findings necessary to make the diagnosis is given.

High-pressure injection injuries to the hand.

Despite their appearance for over 20 years, high-pressure injection injuries to the hand are often grossly undertreated or mistreated, resulting in usually avoidable permanent impairment--often with amputation. Primary care physicians, and especially emergency room physicians, must be aware of the serious nature of this usually innocuous-appearing injury and immediately refer such patients for definitive emergency surgery.
