An Alternative Method for the Measurement of Pelvic Skeletal Asymmetry (PSA) Using an Asymmetry Ratio (AR)
David A. Egan, PT, PhD Joan Cole, PT, PhD Lance 71vomey, PT, PhD
Abstract: This paper presents an alternative method for determining PSA. Frequently, physical therapists rely heavily on visual palpatory techniques for the assessment of pelvic skeletal asymmetry; however, a more objective approach using valid and reliable measurement systems is needed. This study shows how a relatively simple and non-invasive measurement system will provide accurate measurements of PSA. The asymmetry ratio, which is easily derived from these measurements, provides a quantitative measurement and a differentiation between two common types of PSA, leg length discrepancy (LLD) and iliac rotation asymmetry (IRA). A distinct advantage is that the AR provides normalized data that take into account the individual differences in pelvic width. Alternative measurement systems may also be used to estimate AR provided they give reliable measurements of the height and width differences of the pelvic bony landmarks.

Neural Mechanisms Underlying Manual Cervical Traction
Lynley Katavich, Dip Phty(Aack), ADP(OMT), Dip MT
Abstract: Manual therapy is commonly used to decrease pain and improve function of the musculoskeletal system in spite of scant knowledge of the underlying mechanisms. Manual cervical traction is suggested to relieve pain and muscle spasm in the neck and upper quartile. Afferent input generated by these procedures may lower the excitability of (X-motoneuron pools of upper limb muscles. While joint receptors are traditionally viewed as the receptor most likely to evoke responses to manual therapy, a review of the literature into possible mechanisms underlying manual cervical traction suggests stretch generated in cervical muscles and skin during the procedure has the potential to influence the excitability of amotoneurons. An understanding of the receptors and mechanisms underlying manual therapy may allow more effective stimulation, and hence, improved clinical outcomes.

A Critical Review of the Literature on the Treatment of Sacroiliac Joint Syndromes
William L. Oldreive, MSc, BA, MCSP DIPTP
Abstract: A critical review of the literature on the treatment of sacroiliac joint syndromes revealed the use of a large number of techniques, with many incompletely described. There were relatively few results of research into the effectiveness of these various techniques. More comprehensive descriptions of treatment regimes would be helpful and more randomized controlled clinical trials of these techniques are needed.

The Influence of the Cervical Spine on Chronic Headache in Women: A Pilot Study
Jeffrey D. Placzek, MD, PT Brian T Pagett, MPT Paul J. Roubal, PhD, PT Brian A. Jones, MPT Heather G. McMichael, MPT Erin A. Rozanski, MPT Kelly L. Gianotto, MPT
Abstract: This study compares selected posture, mobility, strength and endurance variables in subjects with chronic headaches to the same features in asymptomatic subjects. Two convenience samples of 10 female subjects were obtained: 1) those who experience chronic headache, mean age of 34.2 years (SD=11, range=23-57), and 2) a group not experiencing headache mean age of 30 years (SD=9.6, range=21-50). Measurements compared: 1) cervical range of motion in flexion, extension, rotation, and lateral flexion, 2) cervical strength in flexion and extension, 3) forward head posture (FHP), 4) forward shoulder posture (FSP), and 5) endurance testing of the anterior cervical musculature between the two groups. Statistical analysis was completed using the Kruskal-Wallis test. The headache group was found to have significantly less cervical extension ROM (p<0.05) and lower strength for both the cervical flexor (p=0.001) and cervical extensor (p<0.01) muscle groups; in addition the endurance of the anterior cervical musculature was significantly decreased (p=0.001) as compared to the controls. Forward head and forward shoulder posture measurements did not differ between the two groups.
