neglect, has conflicting evidence in the literature. the authors note that a possible limitation in this approach is the requirement for the patients to actively move the neglected limb, which may not be possible for many patients. constraint-induced therapy (cit), appears to be an effective, long-term treatment for improving neglect in various studies. however, the use of cit is limited to patients who have active control of wrist and hand extension. prism glasses, hemispatial glasses, and eye-patching have all appear to be effective in improving performance on neglect tests. caloric stimulation treatment appears to be effective in improving neglect; however, the effects are generally short-term. the review also suggests that optokinetic stimulation is effective in improving position sense, motor skills, body orientation, and perceptual neglect on a short-term basis. as with caloric stimulation treatment, long-term studies will be necessary to show its effectiveness. a few trunk rotation therapy studies suggest its effectiveness in improving performance on neglect tests as well as the functional independence measure (fim). some less studied treatment possibilities include treatments that target dorsal stream of visual processing, mental imagery training, and neck vibration therapy. trunk rotation therapies aimed at improving postural disorders and balance deficits in patients with unilateral neglect, have demonstrated optimistic results in regaining voluntary trunk control when using specific postural rehabilitative devices. one such device is the bon saint côme apparatus, which uses spatial exploratory tasks in combination with auditory and visual feedback mechanisms to develop trunk control. the bon saint côme device has been shown to be effective with hemiplegic subjects due to the combination of trunk stability exercises, along with the cognitive requirements needed to perform the postural tasks.
