“…The finding of an insignificant effect of non-volar splints on grip MVC is opposite to the pronouncedly inverse influence of splints with volar part on grip MVC shown by past studies [17,36,37,38]. The volar part is supposed to interfere in the transmission of force from hands to objects, similar to the finding that wearing gloves has an adverse effect on grip strength [e.g.…”

“…Shih [34,35] revealed that splints without volar parts affected neither pinch nor grip strength, respectively. This differed from the influence of splints with volar parts on peak grip strength [17,36,37,38]. Furthermore, Chang et al [10] indicated that in the repetitive operation of an in-line pneumatic screwdriver, a higher triggering force was required and a greater hand-transmitted vibration was found; however, the presence of splints did not affect the flexor digitorum EMG.…”

“…Malone et al [23] indicated that wearing splints could significantly reduce wrist extension during wheeling, but did not alter elbow motion or maximal wheeling speed. Additionally, evidence indicates that the grip strength achieved while wearing splints equipped with volar parts was no better, or even worse, than that of free hands in both normal people [17,36,37] and patients with rheumatoid arthritis [38]. Rempel et al [32] also demonstrated that there was an augmentation in CTP while subjects were either wearing splints or performing repetitive tasks as compared with resting, and the influence of a splint on CTP was not significant during the performance of repetitive activities.…”

When peak grip strength is reached may be a useful and interesting index for evaluating strength generation and the relationship between resistance and response time, and as one of selected criteria to quantify the muscle fatigue and the static peak strengths. The present study investigates the influence of wearing splints under different forearm and wrist postures on grip MVC (maximum volitional contraction) as well as the time needed to reach the MVC (denoted by T MVC ). Twenty female college students took part in this experiment voluntarily. The factorial design with four fixed factors (subject, forearm position, wrist deviation, and splint (with and without)) was employed. The forearm positions were set at 0 and 30 degrees internal (Internal-0 and 30) and 30 degrees external shoulder rotation (External-30). The wrist deviations are extension 30 o (E30 o ), neutral (N0 o ), flexion 30 o (F30 o ). The results show that the effect of forearm posture changes the grip MVC pronouncedly, but not the T MVC . The forearm at External-30 generates the least MVC (234.5N), and the other two postures are indifferent from each other (250.3 N vs. 253.2 N). As to the effect of wrist posture, it influences both selected responses, the MVC and the T MVC . The wrist at neutral generates the optimum force (254.4 N), and the other two wrist postures are indifferent (239.6 N vs. 244.0 N). Moreover, wrist posture at E30 o also has the longest T MVC , and the rate of force development is the lowest among the three specified wrist positions. Finally, the presence or absence of splints shifted neither the MVC nor the T MVC .

“…To date, most wrist orthoses have been made of plastic with belts or elastic fabric and with a preshaped aluminum strip on the palmar side. [6][7][8][9][10] They had the merit of resting the affected wrist by immobilization until the acute condition had improved. However, they tended to restrict finger motion, and were not ideal for the activities of daily living.…”

One of the wrist orthoses, the Senami Wrist Supporter (SWS), was applied to 203 rheumatoid wrists in 112 patients who had persistent wrist pain and restricted forearm rotation due to synovitis and instability at the distal radioulnar joint (DRUJ). The study was performed by sending out a questionnaire to the patients about the use of the SWS at home, and examining grip strength and forearm rotation with and without the use of the SWS. The average age of the patients was 61 years, and the average follow-up period was 18 months. The rate of compliance of wearing the SWS at home was 73% on average. It was higher in wrists of Larsen-Dale-Eek (LDE) grades 0, I, and II (normal, slight, and definite early abnormality) than in those of grades III, and IV (medium and severe destructive abnormality). Decreased pain was noted in 52% of the wrists at the time of applying the SWS. The SWS was not used in 10% of the wrists because of remission of pain at follow-up. Grip strength increased significantly (P Ͻ 0.01) and so did forearm rotation (P Ͻ 0.05) by the stabilizing effect of the SWS on the unstable DRUJ. The use of the SWS was confirmed to be an efficient measure to treat painful rheumatoid wrists with early stages of disease at the DRUJ.
