Pressure pain threshold and somatosensory abnormalities in different ages and functional conditions of post-stroke elderly

Table 3 All significant differences between post-stroke elderly with and without spasticity

	p1	Normal Group	Spasticity Group	p2
Elbow Extension	0.495	n = 16 (M = 9, 56.25%)	n = 27 (M = 18, 66.67%)
Erector Spinae L2 (BD)		0.465 (0.183–0.770)	0.740 (0.417–1.207)	0.034*
Knee Flexion	0.252	n = 22 (M = 12, 54.55%)	n = 21 (M = 15, 71.43%)
Erector Spinae L4 (BD)		0.552 (0.287–0.667)	0.953 (0.367–1.600)	0.026*
Rectus Femoris (%)		95.26 (85.73–108.42)	113.78 (97.13–124.69)	0.006**
Knee Extension	0.555	n = 19 (M = 11, 57.89%)	n = 24 (M = 16, 66.67%)
Rectus Femoris (%)		93.5 (82.89–103.31)	112.26 (97.01–125.77)	0.003**

All participants were divided into normal and spasticity group according to the result of Modified Ashworth assessment. Those who were assessed as ‘0’ in certain muscle were distributed to normal group and others were distributed to spasticity group. BD, bilateral difference of PPT values (affected–unaffected); %, ratio of PPT values (affected/unaffected). p1-values came from the Chi-square test to show there is no significant difference of sex composition between groups (p > 0.05). p2-values came from the Mann–Whitney U-test
