Effects of Combining Music Therapy, Light Therapy, and Chromotherapy in the Treatment of Chronic Pain Patients: A Pilot Study

Table 2

Evolution of pain intensity (numerical pain scale ranging from 0 to 10) before and after each therapeutic session.

	Pretreatment		Posttreatment		Change (S)	Change (IS)		d
	Mean	SD	Mean	SD
Session 1:/10	6.4	1.7	4.4	1.9	−2		<0.001	1.0
Session 2:/10	5.2	2.0	3.3	1.6	−1.9	0.8	<0.001	0.9
Session 3:/10	4.9	2.6	3.1	2.2	−1.8	1.6	<0.001	0.7
Session 4:/10	4.3	2.5	2.8	2.4	−1.5	1.2	<0.007	0.6
Mean					−1.8	1.2

Numerical Pain Scale (NS) recorded just before and just after each session (S). IS: change recorded between the end of one session and just before the next. After one week, the sessions lose their effectiveness, with an average loss of 1.2 point on the NS.
