Comparison of self-reported pain intensity, sleeping difficulty, and treatment outcomes of patients with myofascial temporomandibular disorders by age group: a prospective outcome study

Table 5 Comparison of the changes in the scores between age groups

Symptom	M1 (n = 41)	M2 (n = 62)	M3 (n = 76)	p*
Jaw/face pain	-1.4 ± 2.8	-1.9 ± 2.5	-2.0 ± 3.2	0.53
Headache	-0.5 ± 3.1	-1.3 ± 3.1	-1.8 ± 4.3	0.24
Neck pain	0.1 ± 2.4	-0.5 ± 2.7	-0.8 ± 3.9	0.33
Sleeping difficulty	-0.1 ± 2.8	-1.5 ± 3.2	-1.2 ± 4.7	0.08

M1 = less than 20 years; M2 = 20–39 years; M3 = 40 years and older.
The data are presented by the mean ± the standard deviation. The score change is calculated by the difference between the post-treatment and pretreatment symptom scores (i.e., score change = post-treatment symptom score – pretreatment symptom score).
*The p value is based on the Kruskal–Wallis test.
