Functional electrical therapy (FET) is a new term describing a combination of functional electrical stimulation that generates life-like movement and intensive exercise in humans with central nervous system lesions. We hypothesized that FET can promote a significant recovery of functioning if applied in subacute stroke subjects. The study included 16 stroke(More)
Members of a Roma (Gypsy) family with hereditary motor and sensory peripheral neuropathy (HMSN) and concomitant auditory and vestibular cranial neuropathies were identified in Kocevje, Slovenia. The illness begins in childhood with a severe and progressive motor disability and the deafness is delayed until the second decade. There are no symptoms of(More)
This paper presents the analysis of motion of a redundant anthropomorphic arm during the writing. The modeling is based on the separation of the prescribed movement into two motions: smooth global, and fast local motion, called distributed positioning (DP). The distribution of these motions to arm joints is discussed. It is based on the inertial properties(More)
Today most clinical investigators agree that the common denominator for successful therapy in subjects after central nervous system (CNS) lesions is to induce concentrated, repetitive practice of the more affected limb as soon as possible after the onset of impairment. This paper reviews representative methods of neurorehabilitation such as constraining the(More)
This paper describes a clinical randomized single-blinded study of the effects of Functional Electrical Therapy (FET) on the paretic arms of subjects with acute hemiplegia caused by strokes. FET is an exercise program that comprises voluntary arm movements and opening, closing, holding, and releasing of objects that are assisted by a neural prosthesis(More)
Results from a clinical evaluation of Functional Electrical Therapy (FET) in chronic hemiplegic subjects are presented. FET is an intensive exercise that integrates voluntary maximized manipulation and augmented grasping by electrical stimulation of forearm and hand muscles. A total of 16 chronic hemiplegic subjects participated in a six-month long study.(More)
We describe the model and implementation of the hierarchical hybrid method for controlling of the lower-arm (pronation/supination and elbow flexion/extension) in humans with disabilities. The control follows the strategy found in ablebodied humans where the movement is planned based on the task and the most distal part of the arm; yet, the command starts(More)
1 Movements are assessed by 3 two and 2 single axis goniometers and 2 torsiometers (Penny & Giles, UK) measuring 9 joint motions during task performance. Subjects were instructed to wait for audio signal from evaluator and subsequently pick up the object as accurately as possible with self-paced speed and complete task within 10 s. Abstract-In this study we(More)
In the present study, we modeled a reaching task as a two-link mechanism. The upper arm and forearm motion trajectories during vertical arm movements were estimated from the measured angular accelerations with dual-axis accelerometers. A data set of reaching synergies from able-bodied individuals was used to train a radial basis function artificial neural(More)
The non-volitional sudden discontinuation of motor activity, called motor block (MB) or freezing is most commonly associated with Parkinson's disease (PD). MB extends beyond the classical manifestations of PD: akinezia, bradykinezia, rigidity, tremor, and postural instability. MB has been observed and quantified in internally cued repetitive movements such(More)
