ReviewSpeech and language therapy for dysarthria due to non-progressive brain damage.
Dysarthria is a common sequel of non-progressive brain damage (typically stroke and traumatic brain damage). Impairment-based therapy and a wide variety of compensatory management strategies are undertaken by speech and language therapists with this patient population. ⋯ There is no evidence of the quality required by this review to support or refute the effectiveness of Speech and Language Therapy interventions for dysarthria following non-progressive brain damage. There is an urgent need for good quality research in this area.

Since the condition was first described in 1965, the syndrome of normal pressure hydrocephalus (NPH) has conventionally been managed by placement of a cerebrospinal fluid (CSF) shunt. ⋯ There is no evidence to indicate whether placement of a shunt is effective in the management of NPH.

ReviewTherapeutic ultrasound for the treatment of rheumatoid arthritis.
Ultrasound is often used, by rehabilitation specialists, as an adjunct therapy for the symptomatic treatment of rheumatoid arthritis (RA). Its mechanical energy has antiinflammatory as well as analgesic properties. ⋯ The reviewers concluded that ultrasound in combination with the following treatment modalities; exercises, faradic current and wax baths, is not supported and cannot be recommended. Ultrasound alone can however, be used on the hand to increase grip strength, and to a lesser extent, based on the borderline results, increase wrist dorsal flexion, decrease morning stiffness, reduce the number of swollen joints and reduce the number of painful joints. It is important to note that these conclusions are limited by the methodological considerations such as poor quality of the trials, the low number of clinical trials, and the small sample size of the included studies.

Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking. ⋯ The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.

ReviewCognitive behavioural interventions for sleep problems in adults aged 60+.
The prevalence of sleep problems in adulthood increases with age. While not all sleep changes are pathological in later life, severe disturbances may lead to depression, cognitive impairments, deterioration of quality of life, significant stresses for carers and increased healthcare costs. The most common treatment for sleep disorders (particularly insomnia) is pharmacological. The efficacy of non-drug interventions has been suggested to be slower than pharmacological methods, but with no risk of drug-related tolerance or dependency. Cognitive and behavioural treatments for sleep problems aim to improve sleep by changing poor sleep habits, promoting better sleep hygiene practices and by challenging negative thoughts, attitudes and beliefs about sleep. ⋯ When the possible side-effects of standard treatment (hypnotics) are considered, there is an argument to be made for clinical use of cognitive-behavioural treatments. Research is needed to establish the likely predictors of success with such treatments. As it may well be the case that the treatment efficacy of cognitive-behavioural therapy itself is not durable, the provision of "top-up" sessions of CBT training to improve durability of effect are worthy of investigation.
