Manipulative Therapy

Approximately 38 share of the subjects had never received any form of chiropractic adjustment; these subjects were appoint to the experimental base that received the Pierce-Stillwagon cervical adjustment method. The stay subjects were assigned to a control group that received wholly deep muscle massage.

Leg continuance inequality (as careful by the Derifield-Thompson Test) was assessed both prior to and after intercession. LLI was recorded by an observer who wrote down clinician's estimates for each of three head rotations (head cancelled right, head centered, head turned left). During all LLI assessments, clinicians were blind to the group of patients (experimental or control) they were assessing, nor were they aware of whether or not the patient interposition had been given prior to their assessment.

The need for cervical adjustment (or lack thereof) was initially assessed using more than merely arm length estimates. Specifically, this assessment was made using three indices: (1) the Derifield-Thompson measure of LLI; (2) x-rays; and (3) Derma-Therma-Gram (DTG) heat up readings. However, despite three measures being used at the pretest, just now LLI and DTG assessments were made at the posttest, and only LLI assessments were compared in statistical analyses.

reliableness of the Derifield-Thompson Test was give tongue to to be present if there was a lack of statistically large dif

ference between and within clinicians estimates of leg length.

Failure of t-tests and repeated measures statistics (MANOVA, etc.

) to turn up statistical differences in leg length inequality estimates was said to indicate that the Derifield-Thompson Test had both inter-rater and intra-rater reliability.

Failure to evidence statistical differences in leg length (pretest vs. posttest) for both groups was said to cushion lack of confirmation for the effectiveness of the Pierce-Stillwagon method of cervical adjustment. No data was reported for the DTG posttest measures.

The primary weaknesses of the study was the use of the thin sample size, the failure to eliminate from the sample those who students whose low leg length inequalities showed that they were not in need of adjustment, and the failure to frontier the sample only to those who needed cervical adjustment only.

The confoundings associated with the treatment variable render the findings of the study not very significant in the field; this because the confoundings make it difficult to know barely what effects were or were not found. The goal of demonstrating that the Pierce-Stillwagon method of cervical adjustment was effective and that this effectiveness can be
