Effects of multi-sensory stimulation for people with dementia.

BACKGROUND: Over recent years multi-sensory stimulation (MSS) has become an increasingly popular approach to care and is used in several centres throughout Europe. This popularity could be explained by the limited alternatives available to staff and a widely held belief that MSS is a friendly and highly humane approach. A randomized controlled trial was therefore essential to evaluate the effectiveness and extent of the benefits of MSS. AIM: To assess whether MSS is more effective in changing the behaviour, mood and cognition of older adults with dementia than a control of activity (playing card games, looking at photographs, doing quizzes, etc.). METHODS: A total of 136 patients from three countries [United Kingdom (UK), the Netherlands and Sweden] were randomized to MSS or activity groups. Patients participated in eight 30-minute sessions over 4 weeks. Ratings of behaviour and mood were taken before, during and after sessions to investigate immediate effects. Pre-, mid-, post-trial and follow-up assessments were taken to investigate any generalization of effects to cognition and behaviour and mood at home/on the ward or at the day hospital. RESULTS: There were limited short-term improvements for both the MSS and activity groups immediately after sessions, and limited short-term improvements between the groups during sessions. There were no significant differences between the groups when assessing change in behaviour, mood or cognition at home/on the ward or at the day hospital. In the UK, however, behaviour at the day hospital for both groups remained stable during the trial but deteriorated once the sessions had stopped, and active/disturbed behaviour at home improved but likewise deteriorated once sessions had stopped. CONCLUSIONS: Overall, MSS was found to be no more effective than an activity in changing the behaviour, mood or cognition of patients with dementia in the short- or long-term.

Effects of multisensory stimulation in people with Huntington's disease: a randomized controlled pilot study.

OBJECTIVE: To investigate whether behavioural, motor and physiological responses of individuals with Huntington's disease (HD) to a controlled multisensory environment (MSE) are effective as a therapeutic (sustained effects) or leisure (immediate effects) activity. DESIGN: Pilot study--a randomized, controlled, two-group design. SETTING: Specialist residential unit for people with mid-late stage HD. SUBJECTS: Twelve patients with HD (one subject from each group dropped out during the study after week 8 due to medical complications). INTERVENTIONS: Patients attended eight, 30-minute sessions over a four-week period, of multisensory stimulation (MSE, treatment group) or relaxation activities (control group). MAIN OUTCOME MEASURES: Between-group comparisons for changes between assessment sessions for two behavioural assessments: Rehabilitation Evaluation--Hall and Baker (REHAB), Behaviour and Mood Disturbance Scale (BMD); a motor assessment: the dyskinesia section of the St Hans Rating Scale (SHRS); physiological measures: blood pressure, heart rate and respiratory rate. Secondary measures during intervention sessions included behavioural assessment using the Interact. RESULTS: There were no significant differences found between the groups for any main outcome measures made between sessions. The MSE group showed some positive effects within-sessions, with the Interact showing significant between-group differences in immediate effects on mood (p = 0.028). There was also a significantly different change over time for within-session changes in stimulation levels (p = 0.0002) and mood (p = 0.0001) between the groups. No physiological effects were observed in relation to sessions in either group. Two MSE subjects underwent changes in medication during the study period. CONCLUSIONS: There was no therapeutic effect of MSEs over the four-week study period. MSEs appear to be more effective thanconventional relaxation techniques as a leisure activity.
