Randomized Controlled Trial Clinical Trial
Cognitive-behavioral therapy in patients with ankylosing spondylitis in a German self-help organization.
A cognitive-behavioral treatment program for pain control was administered to 22 subjects with a diagnosis of ankylosing spondylitis (AS) in a self-help setting of the German Rheumatism League. A sample of 17 AS subjects from the same setting served as waiting-list controls. The program consisted of training in progressive muscle relaxation, cognitive restructuring, attention related techniques and pleasant activity scheduling, and was aimed at an improvement of self-control strategies. ⋯ Reductions of pain intensity, anxiety, and psychophysiological symptoms were maintained at 12 month follow-up. Although pain reduction was statistically significant, it did not exceed 14% in the pain diary. The more important aspect of the treatment appears to be emotional stabilization and increased feelings of well-being.

Randomized Controlled Trial Clinical Trial Controlled Clinical Trial
Analgesic effects of different pulse patterns of transcutaneous electrical nerve stimulation on cold-induced pain in normal subjects.
The analgesic efficacy of various pulse patterns of transcutaneous electrical nerve stimulation (TENS) were assessed in 84 normal healthy subjects using the cold pressor pain technique. Burst, modulation, random and continuous TENS all significantly elevated ice pain threshold. ⋯ Increasing the size of electrodes reduced the effect of continuous TENS. The clinical implications of these findings are discussed.
