Review Comparative StudyA comparison of physiotherapy techniques for patients with Parkinson's disease.
Despite optimal medical and surgical therapies for Parkinson's disease, patients develop progressive disability. The role of the physiotherapist is to maximise functional ability and minimise secondary complications through movement rehabilitation within a context of education and support for the whole person. What form of physiotherapy is most effective in the treatment of Parkinson's disease remains unclear. ⋯ Considering the small number of patients examined, the methodological flaws in many of the studies and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of any given form of physiotherapy over another in Parkinson's disease. Another Cochrane review, Physiotherapy for patients with Parkinson's Disease, found that there was insufficient evidence to support or refute the efficacy of physiotherapy compared to no physiotherapy in Parkinson's disease. A wide range of physiotherapy approaches were used in these studies and a survey of UK physiotherapists confirmed that they also use an eclectic combination of techniques in the treatment of Parkinson's disease (Plant 1999). Therefore a consensus must be found as to 'best practice' physiotherapy for Parkinson's disease. The efficacy of 'standard' physiotherapy should be proved first before examining variations in physiotherapy methods. Therefore large well designed randomised controlled trials are needed to judge the effect of physiotherapy in Parkinson's disease. After this large RCTs are needed to demonstrate the most effective form of physiotherapy in Parkinson's disease. Outcome measures with particular relevance to patients, carers, physiotherapists and physicians should be chosen and the patients monitored for at least 6 months to determine the duration of any effect. The trials should be reported according to CONSORT guidelines (CONSORT 1996).

ReviewSpeech and language therapy for dysarthria in Parkinson's disease.
Dysarthria is a common manifestation of Parkinson's disease which increases in frequency and intensity with the progress of the disease (Streifler 1984). Up to 20% of Parkinsonian patients are referred for speech and language therapy (S & L T), its aim being to improve the intelligibility of the patient's speech. ⋯ Considering the small number of patients examined, the methodological flaws in many of the studies, and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of speech and language therapy for dysarthria in Parkinson's disease. A Delphi-style survey is needed to develop a consensus as to what is 'standard' S< for dysarthria in Parkinson's disease. Then a large well designed placebo-controlled RCT is needed to demonstrate speech and language therapy's effectiveness for dysarthria in Parkinson's disease. The trial should conform to CONSORT guidelines. Outcome measures with particular relevance to patients should be chosen and the patients followed for at least 6 months to determine the duration of any improvement.

Review Comparative StudyA comparison of speech and language therapy techniques for dysarthria in Parkinson's disease.
Dysarthria is a common manifestation of Parkinson's disease that increases in frequency and intensity with the progress of the disease (Streifler 1984). Up to 20% of Parkinsonian patients are referred for speech and language therapy (S & LT), its aim being to improve the intelligibility of the patient's speech. ⋯ Considering the methodological flaws in both of these studies, the small number of patients examined, and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of any given form of S & LT over another to treat dysarthria in Parkinson's disease. Given the lack of evidence from RCTs to support or refute the efficacy of S & LT in Parkinson's disease (see Cochrane review 'Speech and Language therapy for Dysarthria in Patients with Parkinson's Disease'), the consensus as to what is considered 'best-practice' S & LT must be proved first through a large well-designed placebo-controlled randomised trial before examining variations in S & LT methodology. The design of these trials should minimise bias and be reported fully using CONSORT guidelines (CONSORT 1996). Outcome measures with particular relevance to patients, their carers, physicians and speech and language therapists should be chosen and the patients followed for at least 6 months to determine the duration of any improvement.

Acute psychotic illness, especially when associated with agitated or violent behaviour, requires urgent pharmacological tranquillisation or sedation. Clotiapine, a dibenzothiazepine neuroleptic, is being used for this purpose in several countries. ⋯ We found no significant evidence to support the use of clotiapine rather than other 'standard' or 'non-standard' treatments for the management of acute psychotic illness. The trials included in this review all present important methodological flaws. We do not wish to discourage clinicians from using clotiapine in the psychiatric emergency, we would just like to point out the fact that good quality controlled trials are needed on this subject.

Illness-related malnutrition has been reported in 10-55% of people in hospital and in ill people in the community in areas of food sufficiency. It has been suggested that dietary counseling to encourage the use of energy- and protein-rich foods should be used in preference to oral nutritional supplements in the management of illness-related malnutrition. ⋯ This review highlights the lack of evidence for the provision of dietary advice in the management of illness-related malnutrition. The available data suggest that oral nutritional supplements have a greater role than dietary advice in the improvement of body weight and energy intake. A large adequately powered randomised controlled trial is needed to compare the efficacy of different forms of therapy to increase dietary intake in people with illness-related malnutrition and to examine the impact of this on clinical function and survival.
