PURPOSE This review gives an overview of the current state of research regarding the effectiveness of mirror therapy in upper extremity function. METHOD A systematic literature search was performed to identify studies concerning mirror therapy in upper extremity. The included journal articles were reviewed according to a structured diagram and the(More)
D. M. Jacobs and C. F. Michaels (2006) concluded that aspects of hand movements in lateral catching were predicted by the ratio of lateral optical velocity to expansion velocity. Their conclusions were based partly on a modified version of the required velocity model of catching (C. E. Peper, R. J. Bootsma, D. R. Mestre, & F. C. Bakker, 1994). The present(More)
BACKGROUND After an upper limb amputation a prosthesis is often used to restore the functionality. However, the frequency of prostheses use is generally low. Movement kinematics of prostheses use might suggest origins of this low use. The aim of this study was to reveal movement patterns of prostheses during basic goal-directed actions in upper limb(More)
Point-to-point movements constrained to the horizontal plane are generally straight, although they exhibit slight deviations from straightness. Unconstrained horizontal movements (i.e., movements where the hand is lifted) are more curved in their projection onto the horizontal plane than constrained movements. It has been argued that this difference in(More)
The i-LIMB hand is a novel upper limb myoelectric prosthetic hand with several joints in the fingers and thumb. This study aimed to determine whether this new device had more functionality than a more conventional myoelectric prosthetic hand with only a single joint between the thumb and two fingers. Therefore, a 45-year-old man with a wrist disarticulation(More)
In this article, we aim to strengthen the emerging radical, non-representational, approaches to cognitive science by defusing the worries radical enactivists have with the use of information in the ecological approaches - namely the worry that information carries content. We show that Gibson's later use of the concept is meant to allow for a content-less(More)
OBJECTIVES To analyze work participation, work productivity, contributing factors, and physical work demands of individuals with upper limb absence (ULA). DESIGN Cross-sectional study: postal survey (response rate, 45%). SETTING Twelve rehabilitation centers and orthopedic workshops. PARTICIPANTS Individuals (n=207) with unilateral transverse upper(More)
Sit-to-stand is a fundamental activity of daily living, which becomes increasingly difficult with advancing age. Due to severe loss of leg strength old adults are required to change the way they rise from a chair and maintain stability. Here we examine whether old compared to young adults differently prioritize task-important performance variables and(More)
