OBJECTIVES To investigate the progression of joint damage in early rheumatoid arthritis (RA) using magnetic resonance imaging (MRI) of the wrist and determine whether this technique can be used to predict prognosis. METHODS An inception cohort of 42 early patients has been followed up prospectively for one year. Gadolinium enhanced MRI scans of the dominant wrist were obtained at baseline and...

INTRODUCTION: The identification of COVID-19 pneumonia using chest radiography is challenging. OBJECTIVES: We investigate classification models to differentiate COVID-19-based and typical in radiography. METHODS: use 136 segmented X-rays train evalu

OBJECTIVE The study was performed to evaluate detection of soft-tissue foreign bodies using conventional radiography (film-screen radiography), computed radiography printed on films (computed radiography-hard copy), and computed radiography displayed on a computer workstation (computed radiography-soft copy). SUBJECTS AND METHODS Fifteen foreign bodies of different size, shape, and compositio...

The purpose of this study was to observe changes in electromyographic activity appeared in shoulder and scapular muscles when one wears no wrist extension orthosis, short wrist extension orthosis and long wrist extension orthosis when performing two model assembling operations. The study subjects were 16 adults who use right hand and did not have any functional disorder on their wrist or the up...

OBJECTIVE To develop work guidelines for wrist posture based on carpal tunnel pressure. BACKGROUND Wrist posture is considered a risk factor for distal upper extremity musculoskeletal disorders, and sustained wrist deviation from neutral at work may be associated with carpal tunnel syndrome. However, the physiologic basis for wrist posture guidelines at work is limited. METHODS The relation...

OBJECTIVE To determine the frequency and characteristics of wrist pain in young, nonelite gymnasts over a 1-year training period, and to describe the effects of chronic wrist upon gymnastics training. DESIGN Prospective cohort study. SETTING Los Angeles-based gymnastics club. PARTICIPANTS Forty-seven nonelite female and male gymnasts between 5 and 16 years of age. ASSESSMENTS Each subje...

[Purpose] The aim of this paper was to report the efficacy of kinesiology taping for recovery from wrist pain and limited range of motion (ROM) in a physical therapist with repetitive strain injuries. [Subjects] A 32 year-old male physical therapist developed recurring severe pain in the dominant wrist and limited active ROM with extremely painful supination. [Methods] The kinesiology tape was ...

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...

Synovial chondromatosis of the wrist is rare. We report the case of a 35-year-old man with synovial chondromatosis of the left wrist with an 8-year follow-up. Frequent recurrences finally resulted in total wrist arthrodesis. A review of the literature produced 24 case reports of synovial chondromatosis of the wrist with only three cases showing recurrence.
