Analysis of Biomechanical Properties of the Lumbar Extensor Myofascia in Elderly Patients with Chronic Low Back Pain and That in Healthy People

Table 5

Correlation between the JOA score, VAS score, Cobb angle, and disease course, and biomechanical properties of the lumbar extensor myofascia.

CLBP group	Factor	Muscle tone		Stiffness		Logarithmic decrement
		r		r		r
	JOA score	−0.621	0.01	−0.682	0.01	−0.359	0.023
	VAS score	0.695	0.01	0.715	0.01	0.525	0.001
	Cobb angle	−0.232	0.149	−0.261	0.104	−0.146	0.369
	Duration of disease	0.029	0.861	0.013	0.938	0.115	0.479
Control group	Cobb angle	−0.032	0.843	−0.022	0.895	0.075	0.646

Note. indicates statistically significant difference. CLBP: chronic low back pain; JOA: Japanese Orthopedic Association; and VAS: visual analog scale.
