Exercise in the treatment of clinical anxiety in general practice - a systematic review and meta-analysis.

BACKGROUND: Anxiety disorders are common, yet treatment options in general practice are often limited to medication or CBT. There is a lack of evidence for the effectiveness of exercise in the treatment of anxiety in patients who present to general practice and also about the intensity of exercise required to lead to improvement. The aim of this systematic review was to assess the use of exercise versus waiting list control groups in the treatment of anxiety and also to assess the benefit of high intensity exercise vs low intensity exercise. Long term follow up scores were also analysed. We included patients who met diagnostic criteria for anxiety disorders or had clinically raised anxiety levels on a validated rating scale and performed a subgroup analysis of the outcomes between the two groups. The intervention was any aerobic exercise programme carried out for at least two weeks, or exercise carried out at high intensity for at least two weeks. The comparison groups were either a waiting list control group or low intensity exercise. METHOD: Systematic review of randomised controlled trials. Three databases were searched; CENTRAL, Medline and Embase. Outcome assessment was based on validated anxiety rating scales. The quality of the studies was appraised according to the Cochrane Risk of Bias tool. Effect sizes were calculated using the standardised mean difference. RESULTS: Fifteen studies were identified with a total of 675 patients. Nine trials had participants with diagnosed anxiety disorders and six trials had participants with raised anxiety on a validated rating scale. Aerobic exercise was effective in the treatment of raised anxiety compared to waiting list control groups (effect size - 0.41, 95% CI = - 0.70 to - 0.12). High intensity exercise programmes showed greater effects than low intensity programmes. There was no significant difference in outcomes between groups of patients with diagnosed anxiety disorders and patients who had raised anxiety on a rating scale. Conclusions were limited by the small number of studies and wide variation in the delivery of exercise interventions. CONCLUSION: Exercise programmes are a viable treatment option for the treatment of anxiety. High intensity exercise regimens were found to be more effective than low intensity regimens. The results have implications for the use of exercise schemes in General Practice.

Chronic fatigue syndrome: the nurse's role.

BACKGROUND: Chronic fatigue syndrome (CFS), a disorder of no proven cause, is characterised by extended periods of extreme, debilitating fatigue and related symptoms. This article discusses this distressing disorder and identifies the needs of those who have it. The authors suggest that the nurse could fulfil the role of key professional carer, interacting with the individual with CFS to co-ordinate care and form the pivotal therapeutic relationship. CONCLUSION: CFS remains a chronic illness of uncertain cause and prognosis. For those with CFS, care priorities involve validation, information and advocacy, a therapeutic relationship and co-ordinated care. The particular philosophy of care held by nurses makes them potentially ideal co-ordinators of care for those with CFS.
