The role of the psychologist in multidisciplinary treatments for chronic neck and shoulder pain: a controlled cost-effectiveness study. An exploratory trial of preventative rehabilitation on shoulder disability and quality of life in patients following neck dissection surgery.
This study was designed to determine a cost-effective use of psychologist resources in multimodal cognitive-behavioural treatments (MMCBT) for chronic neck/shoulder pain. A randomised controlled trial was conducted with 66 patients divided in two groups. The first group (A) was treated following the approach of MMCBT with the clinical psychologist only functioning as a "coach" to the other health professionals. In this group, the psychologist had on average 5 hours of input per patients. The second group (B) was treated with the same inpatient MMCBT but with the behavioural component administered by the clinical psychologist directly to the patients. In this second group the psychologist had on average 17 hours of input per patient in the entire intervention. The outcome variables included physical, emotional and social factors, and sick-leave. Both groups showed significant improvements over time. The improvements were evident only in sub-groups, specifically in women. The only significant difference between the groups was in "perceived helplessness" favouring the "psychologist contact" setting. It is concluded that in terms of input of clinical psychology, the treatment setting with the "coaching" technique proved to be the most cost-effective use of the psychologist in the two treatment settings investigated. Patients commonly develop shoulder disability and reduction in quality of life (QOL) following neck dissection surgery. There is a lack of studies investigating the impact of preventative rehabilitation to prevent shoulder disability in this population. An exploratory trial was undertaken to investigate this gap in the head and neck cancer literature. Thirty-two subjects were randomly assigned to either one of two groups: early physiotherapy for a period of 3 months following surgery and current routine inpatient care and advice. Blinded measurement of shoulder function and QOL were recorded pre-operatively and at 1 year following surgery. No difference was found using between-group analysis (Mann-Whitney U-Test) for any outcome measures observed. Descriptive data analysis suggests that subjects receiving early physiotherapy had a perception of increased physical well-being when compared with subjects receiving routine care. There may be some clinical significance that subjects receiving a course of physiotherapy did appear to rate their physical well-being higher than those subjects not undergoing rehabilitation. Further research to investigate the preventative effects of physiotherapy on this population should consider the use of head and neck cancer-specific outcome measurement of both shoulder disability and QOL.

We conclude that there appears to be little scientific evidence for the effectiveness of multidisciplinary biopsychosocial rehabilitation compared with other rehabilitation facilities for neck and shoulder pain. Multidisciplinary rehabilitation is a commonly used intervention for chronic neck and shoulder complaints, therefore we see an urgent need for high quality trials in this field.
