Background Soft-robotic gloves with an assist-as-needed control have the ability to assist daily activities where needed, while stimulating active and highly functional movements within user’s possibilities. Employment of hand glove support might act as training for unsupported function. Objective To evaluate therapeutic effect a grip-supporting soft-robotic assistive device at home during activities. Methods This multicentre intervention trial consisted 3 pre-assessments (averaged if steady...
Decline of hand function, especially reduced strength, is a common problem that can be caused by many disorders and results in difficulties performing activities daily living. A wearable soft robotic glove may solution, enabling use the affected arm repeatedly during functional providing intensive task-specific training simultaneously with assistance function.We aim to investigate therapeutic effect an assistive (Carbonhand).This multicenter uncontrolled intervention study consists 3...
When reproducing a previously perceived force or position humans make systematic errors. This study determined the effect of level on and reproduction, when both target reproduction are self-generated with same hand. Subjects performed tasks at different levels, against fixed handle, task haptic manipulator which applied constant opposing forces. series two interchanging trials: matching an onscreen (reference trial), subsequently without visual feedback (reproduction trial). generated too...
For optimal haptic tele-manipulation system design, it is important to understand the accuracy and limitations of human force perception. Previous research demonstrated that humans generate higher forces when asked reproduce an externally applied force; these studies proposed nervous attenuates feedback from self-generated forces. The goal this study was determine how accurately subjects with same hand over a broad range levels. Subjects (n=10, all right handed) had onscreen target visual...
For patients with post-stroke upper limb impairments, the currently available clinical measurement instruments are inadequate for reliable quantification of multiple such as muscle weakness, abnormal synergy, changes in elastic joint properties and spasticity. Robotic devices to date have successfully achieved precise accurate but often limited one or two impairments. Our primary aim is develop a robotic device that can effectively quantify four main motor impairments elbow.The device,...
In an admittance-controlled haptic device, input forces are used to calculate the movement of device. Although developers try minimize delays, there will always be delays between applied force and corresponding in such systems, which might affect what user device perceives. this experiment we tested whether these a human-robot interaction influence perception mass. manipulator was simulate various masses. staircase design subjects had decide two virtual masses heavier after gently pushing...
Abstract Background Upper limb impairments in a hemiparetic arm are clinically quantified by well-established clinical scales, known to suffer poor validity, reliability, and sensitivity. Alternatively, robotics can assess motor characterizing joint dynamics through system identification. In this study, we establish the merits of quantifying abnormal synergy, spasticity, changes viscoelasticity using identification, evaluating (1) feasibility quality parametric estimates, (2) test–retest (3)...
To assess test-retest reliability and validity of a new diagnostic device, the Shoulder Elbow Perturbator, to quantify muscle weakness, abnormal synergy, (muscle activity-related) spasticity, changes in viscoelastic joint properties elbow.
In an ongoing study, assistive wearable soft-robotic glove is tested at home for 6 weeks by subjects with decreased handgrip strength, due to different hand injuries or diseases, assess whether use of this grip-supporting will result in improved strength/ function. An interim analysis the available dataset 46 participants showed that (unsupported) grip strength and function after using as aid during activities daily living (ADLs) home. After ended, maintained least 4 weeks. Considering...
