The effect of new dynamic splint in pinch strength in De Quervain syndrome: a comparative study

Abstract

Objective For patients with De Quervain syndrome using thumb spica orthosis is restricting, so many patient are dissatisfied with using static model. The aim of this study is to compare the effect of modified dynamic and conventional static orthoses on pinch power and functional abilities of hand in De Quervain syndrome. Method In this quasi-experimental study, palmar and lateral pinch strength of the thumb, pain and functional abilities of hand, patient's satisfaction of orthoses, were evaluated after using modified dynamic and conventional static orthosis in two groups. Results Both orthoses improved palmar and lateral pinch strength of the thumb, pain level and functional abilities. In comparison of mentioned variables, there was no significant difference between two groups regarding to pain recovery and abilities improvement (p > 0.05). However, the satisfaction level of the patients who had used dynamic orthosis was higher (p < 0.05). Conclusion It seems, adding a joint to the static thumb spica leads to patient's relief and consequently to their satisfaction. Implications for Rehabilitation The dynamic thumb spica, is easier to use and patients satisfaction is higher than static thumb spica. Therefore, it can be used for conservative treatment of De Quervain syndrome.

The effectiveness of corticosteroid injection and splint in diabetic de Quervain's tenosynovitis patients

“…[ 24 ] Splinting is important in protecting the joint and, minimizing or eliminating stress in the joint during daily life activities. [ 25 ] In a few studies in the literature on the use of isolated forearm-based thumb splints, the results were not successful. Weiss et al with 93 patients, success rate of 66% in the isolated steroid injection group, 57% in the steroid + forearm-based thumb splint group, and 18% in the isolated forearm-based thumb splint group.…”

Management of de Quervain Tenosynovitis

“…These findings led them to conclude that strict immobilization is not diseasemodifying. Nemati et al investigated the use of a traditional thumb spica cast versus a dynamic splint that allowed some wrist range of motion and found similar improvements in visual analog scale (VAS) pain and Disabilities of the Arm, Shoulder and Hand (DASH) scores, suggesting that strict immobili-zation is unnecessary 24 . In a retrospective cohort study, Lane et al demonstrated that splinting was effective in 15 of 17 patients who presented with mild symptoms but was less effective than CSI in patients with moderateto-severe symptoms 25 .…”

Fatores associados à adesão ao uso de órteses de membro superior sob diferentes perspectivas

“…Sendo o comprometimento na realização de atividades de vida diária fator relevante para alguns, devese considerar o desempenho nas atividades de vida diária ao escolher o modelo de órtese a fim de que não haja restrição da funcionalidade (O' BRIEN L, 2010;COSTA CR, et al, 2015;NEMATI Z, et al, 2016). Santos RF, et al (2017) relata que apesar das tecnologias assistivas proporcionarem funcionalidade há uma interface com o estigma.…”
