Spinal Manipulation and Spinal Mobilization Effects in Participants With and Without Back Pain

Not Applicable
Terminated
Conditions
Back Pain
Registration Number
NCT02660801
Lead Sponsor
Université du Québec à Trois-Rivières
Brief Summary

The objective of the present study is to compare the neuromechanical responses to spinal manipulation and spinal mobilization in participants with chronic nonspecific middle back pain.

Detailed Description

Although evidences suggest a similar effectiveness of spinal manipulation and spinal mobilization, there is no study that compares the neuromechanical effects of these manual therapies in a experimental context and with the standardization of both interventions. Therefore, the objective of the present study is to compare the neuromechanical responses to spinal manipulation (low-amplitude and high-velocity dynamic thrust) and spinal mobilization (repetitions of a low-amplitude and low-velocity nonthrust movement) in participants with and without chronic nonspecific back pain.

Primary Outcome Measures
NameTimeMethod
Muscular Response, Inferior Level Ratio, Normalized RMSDuring the spinal manipulation and mobilization

To assess the muscular response during therapeutic modalities, the resulting bipolar sEMG signals were first digitally band-pass filtered using a frequency bandwidth of 20-450 Hz (2nd order Butterworth filter). For SMa, the peak root mean square (RMS) value was computed for each electrode using a 250 ms window (125 ms before and 125 ms after the peak force). The RMS values obtained for each electrode were then normalized (nRMS) to the respective RMS value calculated during the sEMG normalization trial.

Terminal Spinal Stiffnesstwo-minutes before spinal mobilization delivery up to two-minutes after

Terminal stiffness was defined as the ratio of the variation of force and displacement between 10 and 45 N

Pressure Provoked Painimmediately after the therapeutic modality application

Pressure provoked pain intensity was assessed immediately after each spinal stiffness assessment using a 0 to 100 visual analog pain scale minimum value=0, maximum value=100. 0 is no pain while 100 is the worse outcome

Global Spinal Stiffnesstwo-minutes before spinal manipulation delivery up to two-minutes after

Global stiffness was defined as the slope of the straight-line best fitting the force-displacement data between 10 and 45 N

Muscular Response, Superior Level RatioDuring the spinal manipulation and mobilization

To assess the muscular response during therapeutic modalities, the resulting bipolar sEMG signals were first digitally band-pass filtered using a frequency bandwidth of 20-450 Hz (2nd order Butterworth filter). For SMa, the peak root mean square (RMS) value was computed for each electrode using a 250 ms window (125 ms before and 125 ms after the peak force). The RMS values obtained for each electrode were then normalized (nRMS) to the respective RMS value calculated during the sEMG normalization trial.
