Cervical SNAGs: a biomechanical analysis.

To this end, the present review has attempted to analyse the possible biomechanical effects of a SNAG applied to the articular pillar of the cervical spine. Wall P The placebo effect: This is the author-manuscript version of this work – accessed from http: However, the biomecbanical biomechanical analysis does not indicate as to why any improvement would be further enhanced by ipsilateral active movement.

Mulligan B Mobilisations with movements. Hippokrates, Stuttgart cited in Penning Triano J Studies on the biomechanical effect of a spinal adjustment. This may somewhat explain the clinical finding with cervical SNAGs that the same superoanterior accessory joint movement is needed, cerviccal the movement dysfunction involves rotation or lateral flexion Mulligan Firstly, given that cervical SNAGs are said to have an immediate effect Mulliganit seems likely that their underlying mechanism is either purely mechanical, reflexogenic Herzog et al.

You may be worried about your future, both in respect of finances and More information. This approach is extrapolated from Kaltenborn s theory that decreased joint gliding of the peripheral joints can contribute significantly to joint hypomobility and therefore to impaired joint function Mulligan By biomschanical accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License.

Cervical SNAGs: a biomechanical analysis.

MD; Yurth, Elizabeth F. Chronic whiplash and whiplash-associated disorders: Penning L Physiology and biomechanics: This latter scenario could be effected by applying an ipsilateral accessory glide followed by contralateral active rotation.

With appropriate education and exercises, this modality has been proven to assist in the resolution of symptoms More information. The Effectiveness of Chiropractic Care A substantial number of systematic reviews of literature and meta-analyses. Unilateral application of the accessory movement is recommended by Mulliganas he suggests spinal lesions are generally unilateral. Churchill Livingstone, Edinburgh, pp Mulligan Bb Spinal mobilisations with arm movements further mobilisations with movement.

Its clinical application has been based almost exclusively on convention with little attempt to provide a biological basis and little, if any, empirical evidence as yet to support its efficacy. The helical axis of composite motion Milne suggests that for rotatory cervical movement the axis of motion lies close to the ipsilateral zygapophyseal joint. The New Zealand Journal of Physiotherapy Citations Publications citing this paper. Treatment That Stands Up.


However, it is possible that the unilateral application of a cervical SNAG will produce axial y-axislateral z-axis and sagittal x-axis rotations, as demonstrated during unilateral thoracic manipulation Gal et al. Either mechanism could be a primary or secondary through tractioning of the zygapophyseal joint capsule source of pain and muscle spasm Saboe ; Mercer While there are no data to suggest the resultant joint displacement between the therapist applied superoanterior glide and the opposing forces of muscular contraction and gravity, a review of midlower cervical spine kinematics will facilitate a discussion of the possible articular effects of the chosen technique.

In particular, an examination of their potential biological basis in order to stimulate informed discussion seems overdue. Whiplash is a non-medical term used to describe neck pain More information. This glide is maintained as the patient moves analyiss through the desired range of physiological movement and then whilst sustaining the end-range position for a few seconds.
