BACKGROUND Some risk factors for low-energy wrist fracture have been identified. However, self-reported measures such as health-related quality of life (HRQOL) have not been examined as potential risk factors for wrist fracture. The aims of this study were to compare HRQOL prior to a low-energy wrist fracture in elderly patients (>or= 50 years) with HRQOL in age- and sex-matched controls, and t...

Many diseases of the wrist can be recognized by radiographic changes and quantified by radiographic measurements. The kinematic radiographic measurements are the basis for kinematic studies of the wrist as well as a diagnostic, prognostic and follow- up tool for many conditions of the wrist. We undertook this study to identify the normal variations in the longitudinal and transverse dimensions ...

OBJECTIVE To study the effect of an incident wrist fracture on functional status in women enrolled in the Study of Osteoporotic Fractures. DESIGN Prospective cohort study. SETTING Baltimore, Minneapolis, Portland, and the Monongahela valley in Pennsylvania, USA PARTICIPANTS: 6107 women aged 65 years and older without previous wrist or hip fracture recruited from the community between Septem...

BACKGROUND Forceful activities of the wrist were considered to be a risk factor for the epicondylitis. However, there are still conflicting evidence concerning work-relatedness of epicondylitis. The main problem is that there is little information about which forearm postures are capable of withstanding higher torque loads and the extent of the differences in the torques generated by different ...

PURPOSE Aging is associated with slow reactive movement generation and poor termination. OBJECTIVE We examined the hypothesis that the build-up of excitability in the primary motor cortex in the agonist muscle to generate ballistic wrist flexion and extension and in the antagonist to stop the movement, is lower and slower in old compared with young adults. METHODS We measured the size of th...

The aim of this study was to test the hypothesis in the literature that torque resistance of parkinsonian rigidity is the difference between the independent contributions of stretched and shortened muscles. The hypothesis was tested using muscle-specific stretch-shortening (MSSS) EMG ratio in this study. Nineteen patients with idiopathic Parkinson's disease (PD) and 18 healthy subjects (the mea...

BACKGROUND The hand and wrist bones are infrequent sites for osteoid osteoma, and its diagnosis can be difficult. This paper reports 25 cases of osteoid osteoma in the hand and wrist. METHODS Records of the 25 patients who had pathological conditions of osteoid osteoma of the hand and wrist were reviewed and analyzed. RESULTS Twenty-five cases of osteoid osteoma of the hand and wrist were t...

OBJECTIVES To compare action tremor (AT) during manual tracking in normal subjects and patients with multiple sclerosis with tremor (MS-tremor group) and without tremor (MS-no tremor group), and to differentiate tremor occurring predominantly around the distal joint from that involving the proximal joints of the arm. METHODS Subjects performed both a visually guided ramp tracking task using w...

background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...
