Subjective scales for the evaluation of therapeutic effects and their use in complementary medicine

A randomised controlled study of reflexology for the management of chronic low back pain

The use of complementary and alternative medicine (CAM) for the management of chronic low back pain (CLBP) continues to rise. However, questions regarding the efficacy of many CAM therapies for CLBP remain unresolved. The present study investigated the effectiveness of reflexology for CLBP. A pragmatic randomised controlled trial was conducted. N=243 patients were randomised to one of three groups: reflexology, relaxation, or non-intervention (usual care). All completed a questionnaire booklet before and after the treatment phase, and at six months follow up. This measured their general health status, pain, functioning, coping strategies and mood. After adjusting for pre-treatment scores repeated measures ANCOVA found no significant differences between the groups pre and post treatment on the primary outcome measures of pain and functioning. There was a main effect of pain reduction, irrespective of group. Trends in the data illustrated the pain reduction was greatest in the reflexology group. Thus, the current study does not indicate that adding reflexology to usual GP care for the management of CLBP is any more effective than usual GP care alone.

Developing a self-report outcome measure for complementary and alternative medicine

OBJECTIVE

Our objective was to develop a pilot measure of subjective outcomes of complementary and alternative medicine (CAM). Current options for assessing subjective outcomes in CAM are either too burdensome or fail to represent diverse outcomes. A single measure specifying common, patient-reported outcomes of CAM would be of value.

DESIGN

We conducted a three-phase instrument development study. In phase I, 30 CAM-receiving patients and 12 CAM practitioners completed a battery of standardized measures. Participants identified those standardized items relevant to CAM outcome and suggested additional outcome issues. In phase II, 20 CAM-receiving patients completed a Q-sort to determine which items from phase I were most relevant to CAM outcome. In phase III, five experts reviewed the items from phase II for content validity.

SETTING

An integrative medicine clinic at a private, Midwest US hospital.

PARTICIPANTS

CAM patients, practitioners, and researchers and an outcomes measurement specialist.

RESULTS

In phase I, 30 standardized items were judged relevant to CAM outcome, and 8 additional items were suggested. In phase II, 29 of the 38 phase I items were deemed at least "moderately relevant" to CAM outcome. In phase III, experts added 15 items, dropped 9 items, and altered 3 items. The 35 resulting items were classified into content domains, forming a testable, pilot version of the instrument.

Clients' perceptions of the benefits of reflexology on their quality of life

Awareness has increased among health-care professionals, patients and the general public of the importance of an holistic approach to cancer care. Psychosocial interventions, including complementary therapies, may help to improve the quality of life (QoL) of people with cancer by helping to reduce the distress associated with the diagnosis and treatment of cancer and by facilitating improved psychological adjustment to the experience of cancer. The following article presents anecdotal findings at ARC Cancer Support Centre Dublin, Ireland, of clients' perceptions of the benefits of reflexology interventions on their QoL. Reflexology interventions were perceived to impact positively upon clients' levels of impairment and functional status, including physical and psychological function, with implications for general health perceptions. The paper discusses how these findings might form the basis of further, more rigourous evaluation of the benefits of reflexology for people with cancer at ARC Cancer Support Centre.
