Twelve-year follow-up of a randomized controlled trial of comprehensive physiotherapy following disc herniation operation.

OBJECTIVE: To evaluate the long-term effects of postoperative comprehensive physiotherapy starting one week after lumbar disc surgery. DESIGN: Twelve-year follow-up of a three-armed, randomized, controlled, single-blinded clinical trial. SETTING: Department of Physical Medicine & Rehabilitation. PARTICIPANTS: Of 111 patients following first-time, uncomplicated lumbar disc surgery who participated in the original study and completed the treatment originally allocated, 74 ((67%; 29 (73%) physiotherapy, 22 (58%) sham therapy, 23 (68%) no therapy) completed a 12-year follow-up examination. INTERVENTIONS: In the original study, patients had been randomly assigned to comprehensive physiotherapy, sham intervention (neck massage), or no therapy. MEASURES: Low Back Pain Rating Scale; best score 0, worst score 130 points). RESULTS: At 12 years after surgery, the group participating in comprehensive physiotherapy had significantly better functional outcomes, as rated on the Low Back Pain Rating Score, than the untreated group (mean difference: -13.2 (95% CI: (-25.4; -1.0)). Equally, there was a clinically relevant, non-significant difference between the sham therapy and no therapy (mean difference: -12.5 (95%CI: -26.1; 1.1)). Consequently, the Low Back Pain Rating Score outcome did not differ between physiotherapy and sham therapy (mean difference: -0.7 (95%CI: -14.2; 12.8)). CONCLUSIONS: Participating in a comprehensive physiotherapy program following lumbar disc surgery may be associated with better long-term health benefits over no intervention, but may not be superior to sham therapy.

Bath PUVA and saltwater baths followed by UV-B phototherapy as treatments for psoriasis: a randomized controlled trial.

OBJECTIVE: To evaluate the efficacy of psoralens dissolved in a warm-water bath followed by exposure to UV-A irradiation (bath PUVA) or saltwater phototherapy (SW UV-B) compared with tap-water phototherapy (TW UV-B) or UV-B irradiation alone in psoriasis. DESIGN: Multisite, prospective, randomized, controlled trial with 4 parallel groups. SETTING: Total of 102 dermatologic outpatient clinics. PATIENTS: Total of 1241 patients with stable psoriasis vulgaris and a Psoriasis Area and Severity Index score of 7 or greater. INTERVENTIONS: Four-times-weekly UV-B, TW UV-B, SW UV-B, or bath-PUVA with baths preceding UV irradiation over a maximum of 8 weeks. The UV dose was adapted to erythemal response. MAIN OUTCOME MEASURES: Incidence of therapeutic success, defined as a reduction of the Psoriasis Area and Severity Index or affected body surface area of 50% or more. RESULTS: Patients who received TW UV-B had a significantly higher incidence of therapeutic success than did patients treated with UV-B alone (60.7% vs 43.3%; P<.001; number needed to treat, 5.8; 95% confidence interval [CI], 3.9-10.9). Patients who received SW UV-B or bath PUVA had a significantly higher incidence of therapeutic success than did patients treated with TW UV-B (74.9% vs 60.7%; P<.001; number needed to treat, 7.0; 95% CI, 4.6-14.9; and 78.4% vs 60.7%; P<.001; number needed to treat, 5.7; 95% CI, 4.0-9.7, respectively). Bath PUVA was not superior to SW UV-B (78.4% vs 74.9%; P = .34). CONCLUSION: Bath PUVA and SW UV-B are comparably effective treatments in psoriasis and superior to UV-B and TW UV-B.

A randomized controlled trial on the effectiveness of mild water-filtered near infrared whole-body hyperthermia as an adjunct to a standard multimodal rehabilitation in the treatment of fibromyalgia.

OBJECTIVES: To evaluate whether mild water-filtered near infrared whole-body hyperthermia (NI-WBH) produces an additional benefit when applied as an adjunct to a standard multimodal rehabilitation (MR) compared with MR only in patients with fibromyalgia (FM). METHODS: One hundred thirty-nine patients of a German inpatient rehabilitation hospital meeting the ACR 1990 criteria for FM were randomly allocated to NI-WBH (heating-up to 38.1 degrees C body core temperature followed by a 15 min heat retention period) and MR or MR only, twice a week over 3 weeks. Main outcome measures were affective and sensory pain assessed by a German version of the McGill Pain Questionnaire, measured at baseline, postintervention, 3 and 6 months postintervention and analyzed by intention to treat. RESULTS: Repeated measures analysis of covariance showed significant differences between groups for both primary outcome measures in favor of NI-WBH and MR compared with MR only (P<0.001 for affective pain, P=0.001 for sensory pain). Secondary analyses on pain intensity, FM-related quality of life and tender point assessment yielded similar results. Moderate effect sizes were observed for all outcome measures considered (range, 0.41 to 0.75). NI-WBH related side effects were observed in 14 of 69 participants (20%) but all disappeared in less than 30 minutes. DISCUSSION: The study indicates that NI-WBH is a worthwhile adjunct to MR in the treatment of FM.
