chodilator, at two and four months. Except for the treating chiropractor and one investigator (who was not involved in assessing outcomes), all participants remained fully blinded to treatment assignment throughout the study. Results: Eighty children (38 in the active-treatment group and 42 in the simulatedtreatment group) had outcome data that could be evaluated. There were small increases (7 to 12 liters per minute) in peak expiratory flow in the morning and the evening in both treatment groups, with no significant differences between the groups in the degree of change from base line (morning peak expiratory flow, P = 0.49 at two months and P=0.82 at four months). Symptoms of asthma and use of 3agonists decreased and the quality of life increased in both groups, with no significant differences between the groups. There were no significant changes in spirometric measurements or airway responsiveness. Conclusions: In children with mild or moderate asthma, the addition of chiropractic spinal manipulation to usual medical care provided no benefit.
Constant F, Guiilemin F, Collin JF, Boulange M. Use of spa therapy to improve the quality of life of chronic low back pain patients. Medical Care 1998; 36: 1309-1314. Objectives: This study assessed the effectiveness of adding spa therapy to usual drug treatment in chronic low back pain patients. Methods: A total of 224 patients were assigned randomly to either a treatment (n=128) or a control (n=96) group. Subjects in both groups received usual drug therapy. Those in the treatment group also underwent spa therapy in Vittel, France, for 6 days a week for 3 consecutive weeks. Effectiveness was assessed using a quality-of-life scale (the Duke Health Profile), clinical measures, and the Roland and Morris disability questionnaire. Groups were compared using an analysis of variance with repeated measures. Results: At both 3 weeks and 3 months, patients in the treatment group exhibited significant improvement in measures of: physical and mental dimensions of quality of life, anxiety, depression, pain duration, pain intensity, and functional disability. Conclusion: This study suggests that spa therapy is an effective treatment for chronic low back pain patients.
Davis PT, Hulbert JR, Kassak KM, Meyer JJ. Comparative efficacy of conservative medical and chiropractic treatments for carpal tunnel syndrome: a randomized clinical trail. Journal of Manipulative & Physiological Therapeutics 1998; 21:317-326 Objective: To compare the efficacy of conservative medical care with chiropractic care in the treatment of carpal tunnel syndrome. Design: Two-group, randomized, single-blind trial with 9 weeks of treatment and a 1-month follow-up interview. Setting: Wolfe-Harris Center for Clinical Studies at
Northwestern College of Chiropractic in Bloomington, Minnesota. Patients: Ninety-one of 96 eligible subjects who reported symptoms that were confirmed by clinical exam and nerve conduction studies. Interventions: Interventions included ibuprofen (800 mg 3 times a day for 1 week 800 mg twice a day for 1 week and 800 mg as needed to a maximum dally dose of 2400 mg for 7 week) and nocturnal wrist supports for medical treatment. Chiropractic treatment included manipulation of the soft tissues and bony joints of the upper extremities and spine (three treatments/week for 2 weeks, two treatments/week for 3 weeks and one treatment/week for 4 weeks), ultrasound over the carpal tunnel and nocturnal wrist supports. Main outcome measures: Outcome measures were preand postassessments of self-reported physical and mental distress, nerve conduction studies and vibrometry. Results: There was significant improvement in perceived comfort and function, nerve conduction and finger sensation overall, but no significant differences between groups in the efficacy of either treatment. Conclusions: Carpal tunnel syndrome associated with median nerve demyelination but not axonal degeneration may be treated with commonly used components of conservative medical or chiropractic care.
Eberhart LH, Doring H J, Holzrichter P, Roscher R, Seeling W. Therapeutic suggestions given during neurolept-anaesthesia decrease post-operafive nausea and vomiting. European Journal of Anaesthesiology 1998; 15: 446-452. A double-blind randomized study was performed in 100 patients undergoing thyroidectomy to evaluate the effect of positive therapeutic suggestions made during neurolept-anaesthesia. The classic droperidolfentanyl-N20 technique was used as these drugs preserve the neurophysiological functions required to process the information in the therapeutic suggestions given during general anaesthesia. Patients in the suggestion group heard positive non-affirmative suggestions during the whole operation. An autoreverse tape player was used. The control group listened to an empty tape. Both groups were comparable with respect to demographic variables, anaesthetic technique, drug dosage, duration of anaesthesia and surgery. Patients in the suggestion group suffered significantly less from post-operative nausea or vomiting (suggestion: 47.2% vs. control:85.7%) and required less anti-emetic treatment (suggestion:30.6% vs. control:68.6%). We conclude that therapeutic suggestion heard during neurolept-anaesthesia are processed and decrease post-operative nausea and vomiting in patients after thyroidectomy.
