OBJECTIVES After stroke, abnormal arm posture due to spasticity in a functionally useless arm may interfere with self care tasks. In these patients botulinum toxin treatment presents an opportunity to reduce disability. The purpose was to investigate whether reduction in spasticity after botulinum toxin treatment translates into reduction in disability and(More)
OBJECTIVES Spasticity can contribute to poor recovery of upper limb function after stroke. This is a preliminary evaluation of the impact of botulinum toxin treatment on disability caused by upper limb spasticity after stroke. METHODS Seventeen patients with severe spasticity and a non-functioning arm were treated with intramuscular botulinum A neurotoxin(More)
We developed a system for quantitatively measuring arm movement. Our approach provides a method to simultaneously capture upper limb kinetic and kinematic data during assisted passive arm movements. Data are analysed with respect to Cartesian and upper limb coordinate systems to obtain upper limb joint angles and torques. We undertook an evaluation of the(More)
This paper presents a control scheme for a dual robot upper-limb stroke rehabilitation system. A model of the human arm is outlined and used to formulate an admittance controller operating in human upper-limb joint space. Initial results are provided together with a discrussion of future work.
OBJECTIVES (1) To present a measurement protocol for assessing associated reactions (AR) in the paretic arm and (2) to use it to investigate the pattern of AR and its association with spasticity. SETTING Inpatient rehabilitation unit. DESIGN Associated reactions in 49 adults with stroke were measured in terms of force generated, electrical muscle(More)
OBJECTIVES (1) To establish the feasibility of myotatic reflex measurement in patients with head injury. (2) To test the hypothesis that cerebral dysfunction after head injury causes myotatic reflex abnormalities through disordered descending control. These objectives arise from a proposal to use reflex measurements in monitoring patients with head injury.(More)
The nature of rehabilitation medicine is outlined in terms of its objectives, its methods, the patient groups which it seeks to help and its relationships to other specialties. Some major advances of recent years are discussed, such as the development of the impairment/disability/handicap framework. With particular emphasis upon neurological rehabilitation,(More)
