- Abstract
- Objective The objective of this study was to investigate whether Isokinetic Muscle Energy Technique (MET) and Proprioceptive Neuromuscular Facilitation (PNF) applied to the Cervical Erector Spinae (CES) muscles have an impact on the postural sway (standing balance) and eventually which technique would be more effective. The investigation considers the important role that proprioceptive afferent information coming from the CES muscles has in maintaining balance, together with that from the visual and vestibular systems. The rationale for this project is that cervical muscle weakness, often found in subjects suffering from neck pain, produces an altered proprioceptive input resulting in cervicogenic dizziness and unsteadiness. This project investigated whether strengthening of the CES muscle using Isokinetic MET and PNF initiated a change to the body’s central point of balance. Methods 42 subjects aged between 18 and 40 (8Ml rangel8 25) were enrolled in a single-blind, randomized, controlled experiment which took place at the European School of Osteopathy (ESQ). Subjects were randomly allocated in three equal size groups (Control, Isokinetic MET or PNF). Subjects in Isokinetic MET and PNF groups received treatment which consisted of 3 active extensions of the neck against resistance, starting from a flexed position, using 20% (MET) or 70% (PNF) of strength. The subject in the control group laid supine on a bench for the equivalent time it took to perform the treatment on the experimental group. The subjects had their sway measured 3 times for 30 seconds before and after the interventions using a Kistler Force Platform ( KIS) . Pre and post data was transformed within MS Excel in order to obtain the Planar Sway. Results There was a reduction of postural sway in both the PNF (p= 0.397) and MET (p= 0.228) groups. Sway increased in the control group with a p value of 0.300. However the variance of sway calculated within the 3 groups pre and post the intervention, was not of statistical significance. Also the variance in sway calculated either in centimetres (p=O.411) and percentage (p=O.256) between the 3 groups resulted not to be of statistical significance. Conclusion No clinical significant difference was found when comparing the effectiveness of Isokinetic MET and PNF techniques. The null hypotheses cannot be rejected and no conclusion can be made due to limitations of the research and low subject number.
