“…The distal goniometry marker was placed along the third metacarpal bone, and the proximal maker was placed on the dorsal surface of the forearm along the radius. 8 After the attachment of the markers, the subject was seated with their humerus positioned at 0° abduction in the frontal plane and 0° fl exion in the sagittal plane. The elbow joint was held at 90° of fl exion and the forearms positioned at 0° of pronation ( Fig.…”

We investigated the characteristics of the wrist joint motion in patients with rheumatoid arthritis (RA), using a biaxial flexible goniometer. Wrist joint range of motion and velocity were measured on the dominant hand in RA patients (n = 22) and normal individuals (n = 5). We investigated flexion-extension (FE) task, radial-ulnar deviation (RUD) task, and functional motion tasks, such as writing letters or unscrewing the lid of a jar. In normal individuals, there was cooperative coupling of FE and RUD during wrist movement, and this coupling motion was essential for normal wrist movements. On the other hand, in RA patients, wrist joint range of motion was restricted at various degrees, with reduced joint motion velocity that was severe on RUD. Functional wrist motion tasks indicated circumductive movement with both FE and RUD in normal individuals, whereas the direction of movement was limited in RA patients, and results revealed failure of cooperative coupling of FE and RUD. Our results indicate that disturbed coupling of FE and RUD results in difficulties in the cooperative movements and have great influence on the daily activities in RA wrist joint.

“…R is the forearm rotation angle and C is a transducer-dependent constant. Ojima et al (1991) measured the output of the electrogoniometer during wrist circumduction using a specially developed calibration apparatus. It consisted of a horizontal flat board and table, a universal joint at the end of the board, a metal straight bar joined to a universal joint, and a vertical board with a round hole and a sliding side bar.…”

“…Typically, goniometers are relatively small and lightweight offering quick and objective measurements of wrist joint motions (Buchholz & Wellman, 1997;Hansson, Balogh, Ohlsson, Rylander, & Skerfving, 1996;Nicole, 1987;Ojima, Miyake, Kumashiro, Togami, & Suzeki, 1991). Numerous studies have already been performed using electrogoniometers (goniometers with electrical output) in the laboratory, the factory, and in clinical fields.…”

“…In a clinical study, Ojima et al (1991) obtained preliminary data on the angular velocitywrist angle loci of healthy men. The loci represented the continuous change of angular velocity during wrist circumduction, and the distance from the origin to a locus means the angular velocity at the direction.…”

“…For example, Smutz, Serina, and Rempel (1994) employed an electrogoniometer for measuring wrist posture in their ergonomic assessment of keyboard design. Moore et al (1991) used the electrogoniometer to quantify wrist motion of ergonomic risk factors, and Ojima et al (1991) performed a dynamic analysis of wrist circumduction using the electrogoniometer in the clinical field. However, in all these studies extensive calibration techniques were required.…”

Wrist and tendon dynamics as contributory risk factors in work-related musculoskeletal disorders

2005

View full text Add to dashboard Cite

Many studies have shown that repetitive wrist motion is a major risk factor for work-related musculoskeletal disorders (WMSDs). Specific contributory factors include wrist and tendon dynamics. The authors present recent methodological advances, epidemiological studies, and biomechanical models estimating the effects of wrist dynamics on internal tendon force as a theoretical basis for the risk of incurring a WMSD. These biomechanical models utilize either the reduction method or the optimization method to solve the indeterminate problem resulting from too many internal variables. Generally, the optimization methods show the best agreement with direct in vivo tendon force studies. For the models of pinch grips, the average ratio of tendon forces to external forces ranges from 1.8 to 3.5, while for direct tendon measurements, the ratio ranges from 1.73 to 7.92. Similarly, high contributions of flexor tendons for pinches and grasps are found in both the models and direct tendon measurements. These high tendon forces combined with wrist dynamics may be a significant factor in the development of WMSDs.
