The rehabilitation of survivors of stroke places heavy demands on NHS resources. Studies investigating the efficacy of stroke rehabilitation have produced equivocal results.
In this paper we focus on the effects of cognitive deficits on motor functioning (in particular, disorders of praxis and attention) and report some results of particular relevance to physiotherapists. For instance, a symmetrical approach to treatment may not only improve motor function but may also help reduce the severity of unilateral neglect (ie encouraging the patient to orient visually to the affected side should improve the ability to attend to and to be aware of the affected side of space. Motor cues are more likely to be effective than visual cues if motor performance is required, and in particular cueing is,most likely to be effective if it is initiated by a patient rather than a therapist.
Simultaneous bi-lateral exercises should be avoided unless attempts are made to overcome any effect of extinction, where a patient may attend only to the unaffected limb. In addition, cases of dyspraxia show that palogical functioning may be transferred between the hemispheres. Sequential bi-lateral exercises are to be preferred; the effect of the intact limb performing a pattern of movement may provide the visual experience of what the movement should be, and there also may be actjvation of homologous motor areas via the corpus callosum which may facilite the normal movement pattern.
Left neglect, also known as unilateral neglect or hemispatial neglect, is one of the oddest symptoms of a brain injury. It can also be one of the most troublesome symptoms. Left neglect is a deficit that occurs following an injury to the right side of the brain. Due to the injury, the brain has difficulty paying attention to items on the left side. This is generally most apparent in difficulties noticing items visually on the left side. For instance, a survivor with left neglect may bump into frames of doors on the his or her left or miss eating food on the left side of his or her plate. It appears as if he or she is blind to items on the left but this is not a true vision issue. It is an attention issue. The brain is not attending to information on the left. The survivor can have…
