Concurrent validity of an electronic descriptive pain scale.

The study objective was to assess the concurrent validity of the Electronic Descriptive Pain Scale (EDPS), a pain scale built into a transcutaneous electrical nerve stimulation device. One hundred patients in an outpatient physiotherapy (PT) clinic participated (mean age 41.30 years, SD 13.

The use of topical 4% lidocaine in spheno-palatine ganglion blocks for the treatment of chronic muscle pain syndromes: a randomized, controlled trial.

To assess the efficacy of 4% topical lidocaine in spheno-palatine blocks, a randomized controlled trial was carried out on patients with chronic muscle pain syndromes. Sixty-one patients (42 with fibromyalgia (FM) and 19 with myofascial pain syndrome (MPS)) completed the trial. Outcome measures included pain intensity, a daily pain diary, headache frequency, sensitivity to pressure using a dolorimeter, anxiety, depression, and sleep quality.

The concept of primary fibromyalgia (fibrositis): clinical value, relation and significance to other chronic musculoskeletal pain syndromes.

PFS, MPS and TMPDS can be identified using positive diagnostic criteria among patients presenting with chronic pain. A directed rather than exhaustive search for organic diseases known to coexist with these syndromes is usually all that is necessary. Criteria are presently empirical but do identify homogeneous populations of patients for study and treatment.
