Trapezius fibre muscle analysis: A pilot inter/intra-examiner reliability study
Abstract: This paper is an evidence-based report of DeJarnette’s ‘trapezius fibre technique.’ DeJarnette describes that the palpation of the trapezius muscle begins at the lateral border of T1 and moves out laterally in 7 equally spaced steps to finish at the acromioclavicular junction. The relationship between a palpated nodule and its causative vertebrae is documented in chart-form. The indicated thoracic or lumbar vertebrae shows irritation or off-centering on digital palpation That vertebra is designated as the one causing the greatest stimulation of the trapezius muscle. Inter- and intraexaminer reliability was determined in this study with a cohort N=36 Australian chiropractors trained (advanced certification in Sacro Occipital Technique) and experienced (m=12y, R=r=12-34y) in the application of the trapezius fibre technique. In 72% (26/36) of cases there was at least one nodule/no nodule located by at least two examiners. The reliability of the examiners in so far as they could detect the same nodule on all three occasions was impressive and far greater than the inter-examiner reliability. Indeed there were 10 out of the 18 occasions where the one nodule was identified on all three occasions. We conclude that the examiners were relatively able to reliably detect nodules in the trapezius muscle.

Lumbosacral transitional vertebra as a potential contributing factor to scoliosis: a report of two cases
Abstract: Lumbosacral transitional vertebrae (LSTVs) are the most common congenital anomaly of the lumbosacral spine that presents either as L5 sacralisation or S1 lumbarisation. Although most of the LSTVs are of minor clinical importance, these anomalies may contribute to disruptions in biomechanics and alterations in spinal and paraspinal structures. Here, we present two cases of adolescent idiopathic scoliosis to illustrate some overlooked effects of a unilateral LSTV on spinal deformity. Cure correction was not attained in both cases. While a unilateral LSTV was on a different side of their lumbosacral spine, it is incidentally noticed that the direction of the curve was convex on the contralateral side of the LSTV. Most likely, unilateral LSTVs on certain occasions could cause the growing spine to curve and rotate. The aim of this report is to demonstrate an overlooked association between minor anomalies and the growing spines, which may be important to tailor an appropriate treatment plan.
