The interexaminer reliability of a galvanic skin response instrument.

Objective: To determine the interexaminer reliability of a protocol of use of a galvanic skin resistance device for detection of low resistance areas along the spinal column, in relatively pain-free subjects.

Design: A blinded investigation of concordance of skin resistance examination findings over the spinal column using two clinicians experienced in the use of the instrument.

Setting: A private practice chiropractic outpatient clinic.

Temporomandibular disorder associated with sacroiliac sprain.

A case of the external derangement-type temporomandibular disorder (TMD), temporarily relieved following chiropractic sacro-occipital technique (SOT) treatment, including SOT category II blocking to reduce sacroiliac sprain, is presented. Symptom exacerbation midway through the course of treatment followed additional dental work; symptom remission followed additional SOT treatment. Freedom from symptoms is maintained with a 3-wk treatment interval.

Effect of cervical spinal adjustments on lumbar paraspinal muscle tone: evidence for facilitation of intersegmental tonic neck reflexes.

Objectives: To determine whether spinal adjustments, delivered to the upper vs. lower cervical spine, might result in tonic neck reflex-induced alterations in the activity of the lumbar paraspinal musculature.

Design: Randomized, double-blind, before/after treatment comparisons.

Skin temperature assessment for neuromusculoskeletal abnormalities of the spinal column.

Objective: A qualitative review of the scientific literature on thermographic instrumentation for detecting neuromusculoskeletal abnormalities of the spinal column was made. Electronic infrared instrumentation (telethermography), liquid crystal thermography and various hand-held devices were scrutinized in terms of reliability and comparison with other diagnostic tests (e.g.

Who's interested in chiropractic history?

Objective: To determine the extent of interest in chiropractic history among chiropractors in various nations, states and provinces.

Data Sources: The worldwide chiropractor population distribution was determined by noting the circulation of the biweekly magazine, Dynamic Chiropractic. Interest in chiropractic history among chiropractors was implied by inclusion in the Membership Directory of the Association for the History of Chiropractic (AHC).

Comparisons between active vs. passive end-range assessments in subjects exhibiting cervical range of motion asymmetries.

Objective: To compare cervical range of motion values following active (nonpractitioner-assisted) vs. passive (practitioner-assisted) movement of the head to end range.

Design: Randomized, double-blind, within-subject comparisons.

Effectiveness of upper versus lower cervical adjustments with respect to the amelioration of passive rotational versus lateral-flexion end-range asymmetries in otherwise asymptomatic subjects.

The effects of cervical spinal adjustments delivered bilaterally either to the upper cervical region (C2-C3) or to the lower cervical region (C6-C7), were compared in groups of asymptomatic subjects exhibiting goniometrically verified left-right rotational or left-right lateral-flexion passive end-range asymmetries of greater than 10 degrees. Goniometric evaluation both prior to, and again within 30 min following treatments revealed that lower cervical adjustments were far more effective for the amelioration of lateral-flexion asymmetries than were upper cervical ones, whereas upper cervical adjustments were found to be more effective for the amelioration of rotational asymmetries than those delivered to the lower cervical region. These results are consistent with the view that passive movement restriction exhibited along the rotational axis is attributable to factors related primarily to the upper cervical region, whereas restrictions of passive movement along the lateral axis are more attributable to factors related to the lower cervical region.

Effects of cervical adjustments on lateral-flexion passive end-range asymmetry and on blood pressure, heart rate and plasma catecholamine levels.

The biomechanical and physiological effects of a single, unilateral lower cervical spinal adjustment delivered to the most restricted side of cervical lateral-flexion passive end-range were examined. Only healthy, asymptomatic male subjects who exhibited goniometrically verified lateral-flexion passive range of motion asymmetries of 10 degrees or greater on the morning of the experiment were chosen for the study. Posttreatment goniometric measurements revealed that in sham-adjusted controls, mean lateral-flexion asymmetries had not changed significantly during the 4-hr time period examined.

Interexaminer reliability of eight evaluative dimensions of lumbar segmental abnormality.

The interexaminer reliability of noninvasive methods of examining lumbar spinal segments is not well established. In this project the interexaminer reliability of three experienced chiropractic examiners, who evaluated 21 symptomatic and 25 asymptomatic subjects, was explored. Eight noninvasive segmental examination strategies (dimensions) were employed at each spinal segment from T11/T12 through L5/S1.

Time course considerations for the effects of unilateral lower cervical adjustments with respect to the amelioration of cervical lateral-flexion passive end-range asymmetry.

The initial effectiveness as well as the temporal stability of the effect of cervical spinal manipulation with respect to the amelioration of goniometrically verified cervical lateral-flexion passive end-range asymmetry was examined. Responses of two groups of pain-free subjects were compared: a) those exhibiting end-range asymmetries of greater than 10 degrees who, in addition, had suffered previous neck trauma, and; b) those who happened to exhibit end-range asymmetries of greater than 10 degrees but who had no history of prior neck trauma. All subjects received a single lower cervical adjustment delivered to the side of most-restricted end-range, and goniometric reassessments were performed 30 min, 4 hr, and 48 hr following the adjustment.
