Randomized Controlled Trial Multicenter Study
Effectiveness of a home exercise programme in low back pain: a randomized five-year follow-up study.
Therapeutic exercise has been shown to be beneficial in decreasing pain and in increasing functioning in patients with chronic low back pain. However, longitudinal follow-up studies are small in number, and often limited in the numbers of subjects due to drop-outs. In addition there is a shortage of real control groups in most cases. The purpose of the present study was to describe long-term changes in intensity of low back pain and in functioning for two study groups five years after undertaking a home exercise programme. ⋯ The present randomized study indicates that supervised, controlled home exercises lead to reduced low back pain, and that positive effects were preserved over five years.

Randomized Controlled Trial
Is mechanical pain threshold after transcutaneous electrical nerve stimulation (TENS) increased locally and unilaterally? A randomized placebo-controlled trial in healthy subjects.
It is not fully understood how transcutaneous electrical nerve stimulation (TENS) intensity affects mechanical pain threshold. ⋯ TENS administered at a strong but comfortable non-painful stimulation intensity increases mechanical pain threshold ipsi-laterally in healthy subjects, whereas TENS administered at sensory threshold intensity does not. TENS may be ineffective if electrodes are placed contralaterally or distant to the pain site and if stimulation intensity levels are not titrated to subjective strong levels. Further clinical trials are needed to clarify if these findings may also be generalized to populations of chronic pain sufferers.

The present study evaluated whether patients with chronic neck pain demonstrate characteristic angular movement deviations during repeated cervical spine movements. ⋯ Maximal cervical ROM was significantly lower, and movement variability was significantly higher, in patients compared with healthy control subjects. The differences of cervical motion variability point towards increased movement irregularities in patients with chronic neck pain. The present study shows evidence to support the hypothesis that additional information may be gained from the analysis of movement variability.
