Interexaminer agreement on palpatory diagnosis and patient self-assessment of disability: a pilot study.

To evaluate interexaminer agreement on palpatory diagnostic findings, we compared interexaminer results, patient disability self-evaluations, and assessment of patients' progress by referring physicians. Three examiners (two clinicians and a third-year osteopathic medical student fellow) monitored patients' progress using negotiated examination procedures. The patients were examined independently by each examiner at each of eight weekly visits. Patients completed a disability assessment form at each visit, and the referring physicians recorded changes in their patients' condition. The patients' disability self-rating and examiner test results did not show clear correlation. There was a 62.2% agreement between the two physician examiners when the general descriptors "improvement," "no change," or "aggravation" were used. The student examiner's agreement with the clinician examiners was 60.2% and 51.8%. Interexaminer agreement of findings from osteopathic testing procedures appears to depend on general clinical experience and specific experience with the testing procedures.

Quantifying passive resistance to motion in the straight-leg-raising test on asymptomatic subjects.

The clinician needs an objective way to measure limb motion in the straight-leg-raising test. A biomechanical algorithm was used to quantify resistance to motion in 15 asymptomatic subjects. Measurements from a pendulum electrogoniometer and hand-held load cell were used to calculate a moment representing passive resistance to motion. After three measurement trials, significant increases in range of motion (4.7%) and moment (8.4%) occurred. Then, an isometric contraction-relaxation of the hip extensors produced a highly significant increase in motion (8.8%) but decrease in moment (< 14.3%). A third order polynomial fit of moment per angle stratified the sample into two groups according to their change in moment. Motion in group 1 increased 8.0%, and in group 2, 9.5%. However, group 1 had no change in moment whereas group 2 had a highly significant decrease in moment (22.9%). The measured change in resistance demonstrated that a simple biomechanical algorithm quantified properties in a clinical test that were not observed in range of motion alone.

Humans

Incidence of spinal palpatory findings: a review.

Epidemiologic studies of the incidence of somatic dysfunction in a normal or asymptomatic population are needed to evaluate somatic dysfunction as an etiologic factor or as a reflection of disease. Nine studies of the incidence of spinal palpatory findings are reviewed to see if there are commonalities in the patterns of somatic dysfunction, and whether insights into the nature of spinal dysfunction can be gained by an overview of these studies.

Chronic cervical dysfunction: correlation of myoelectric findings with clinical progress.

In this pilot study, four patients with motion impairment and chronic cervical pain after cervical spine injury received osteopathic manipulative treatment for spinal dysfunction for periods in excess of 3 months. Records were compared for changes in the patient's subjective complaints, in the physician's findings, and in the standardized measurement of electrical activity of the cervical spine musculature. All three measures demonstrated parallel improvement in the health status of these patients. Attention to functional aspects of a neuromusculoskeletal problem appears to provide reliable indicators for directing treatment of somatic dysfunction and registering both subjective and objective change.
