Old Dad Chiro comes to Portland: rediscovering DD in Oregon, 1908-10.

This paper sketches Palmer's Portland period, and relies upon five issues of DD's periodical, the Chiropractor's Adjuster, to supplement traditional sources. The early activities of the D.D. Palmer College of Chiropractic are reviewed, and Palmer's travels throughout the region are noted. Old Dad Chiro's widespread influence in the profession is apparent from the diverse correspondence reprinted in his magazine, including letters from chiropractors in at least 22 states. During his Portland years his intent to "adjust" the "mistaken" ideas of chiropractors and his anger at son BJ became plainly and painfully evident. The founder's activities in Portland gave impetus to chiropractic education in the Northwest, and his schools' successor, the Oregon Peerless College of Chiropractic & Neuropathy, continued to operate for several years until its merger with another forerunner of today's Western States Chiropractic College. Most importantly, Palmer's stay in Oregon saw perhaps the first publication of his final theories of chiropractic, and gave rise to his classic text, The Chiropractor's Adjuster: the Science, Art and Philosophy of Chiropractic.

Interexaminer reliability and discriminant validity of inclinometric measurement of lumbar rotation in chronic low-back pain patients and subjects without low-back pain.

The interexaminer reliability of an inclinometer procedure to measure lumbar rotation was evaluated by two chiropractic clinicians who examined 25 chronic (greater than 6 months) low-back pain patients and 25 subjects without low-back pain. These groups were compared for differences in mean left, right, and total rotation. Patients who had lumbar spinal surgery were excluded. Twenty-eight men and 22 women, ranging in age from 28-38 years, were evaluated. Reliability between examiners was evaluated by Pearson's correlation coefficient and the intraclass correlation coefficient. All coefficients were significant (P less than 0.01). Errors in prediction and examiner disagreement were evaluated by the standard error of estimate and the interexaminer measurement error. The standard errors of estimate (range: 1.4-4.4) and the interexaminer measurement errors (range: 3.8-10.4) were large compared to the scale of measurement. An analysis of variance of differences between the chronic low-back pain patients and asymptomatics revealed significantly more left rotation in the asymptomatic subjects (F = 8.4; df = 1; P less than 0.006). Also, there was significantly more total rotation in the asymptomatic subjects (F = 4.143; df = 1; P less than 0.048). However, because of the large error attributed to this procedure, it is not possible to say whether the difference between the two groups is a result of the large error or some "real" difference. Therefore, the procedure described in this study should not be used as a clinical outcome measure.

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). DATA EXTRACTION: An interest index was derived by expressing the number of members of the AHC as a percentage of the chiropractor population in each region. DATA SYNTHESIS: Worldwide membership in the AHC involves less than 1% of the total estimated chiropractor population; Canadian chiropractors demonstrated twice as much interest proportionately compared to all other members of the profession. CONCLUSIONS: Reasons for the minimal interest in chiropractic history are considered, and recommendations for increasing historical interest and scholarship are provided.

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. Marginal to good agreement beyond chance was noted for palpatory pain over osseous structures and in paraspinal soft-tissues. Weaker and less frequently, significant concordance between examiners was noted for detection of temperature differences (greater than or equal to 1.5 degrees F) between adjacent segments and for visual inspection for segmental abnormality. Little significant agreement between examiner was found for active and passive motion palpation, muscle tension palpation and misalignment palpation. This study suggests that "subjective" findings (pain) may be among the most reliable of conservative spinal observations. Weak but significant correlations were found when positive findings for the eight dimensions at each lumbar segment were summed to form a composite joint abnormality index. When the multidimension index was developed using the four most reliable dimensions, slightly stronger correlations were found. The strongest agreement between examiners tended to be found in the lower lumbar spine.

Interexaminer reliability of the innatometer.

Medical doctors can't understand it because it's so Abstract. Get the BIG IDEA and all else follows. Its as simple as that. It works, it gets results, and that's what counts. Enuf said!

Intra- and interobserver reliability of passive motion palpation of the lumbar spine.

Sixty student volunteers were assessed for fixation in the lumbar spine using a passive motion palpation protocol. Subjects were examined in random order by two experienced chiropractors. Every subject was evaluated twice by each examiner. Fixations were judged present or absent for each of five lumbar motion segments. Moderate test-retest agreement beyond chance was noted at L1/2, minimal reliability at L4/5, and no significant agreement within examiners was detected for mid-lumbar segments. Interexaminer agreement beyond chance was poor for all segments assessed. When segments were grouped regionally and re-evaluated, some increase in intrarater agreement was evident, especially at L4/5/S, but interrater agreement was still absent.

Journal of Manipulative & Physiological Therapeutics: a bibliographic analysis.

The first 9 years of the Journal of Manipulative and Physiological Therapeutics (JMPT) (1978-1986) were surveyed to determine concentrations of research activity, educational backgrounds of contributors, sources of funding for chiropractic science, and the volume and kinds of research in chiropractic. Most articles were authored by chiropractors but a fourth of all articles included contributors with scientific/academic doctorates. Most chiropractors were affiliated with a chiropractic college, but collaboration among chiropractic colleges was rare. A recent increase in contributions from private practitioners was also evident. Authors with medical training were uncommon (6%). National College and Canadian Memorial together accounted for 43% of all articles, and 72% of papers whose authors gave chiropractic college affiliations. Authors acknowledged 30 funding sources, and the Foundation for Chiropractic Education and Research (FCER) accounted for a third of all grants (18 of 55). Empirical studies increased in frequency from 1978 to 1986, but accounted for less than half of the papers. Case reports have been the most common form of original data report; 39 were published in JMPT during the 9 year period. Controlled clinical trials of chiropractic healing methods were extremely rare (3 of 334 papers). A need for greatly expanded clinical research in chiropractic is suggested.
