Comparison of plantar fascia thickness between supine and prone positions with the ankle in a 15° plantarflexion posture

Portion of plantar heel	Position		p value§
	Supine	Prone
Medial	5.0 [4.3; 5.8]	5.0 [4.4; 6.0]	0.052
Central	4.7 [4.2; 5.4]	4.9 [4.2; 5.4]	0.062
Lateral	4.5 [4.1; 5.0]	4.6 [4.1; 5.1]	0.674

Measured thickness (mm) values are presented as median [interquartile range; 25th–75th] as data was not normally distributed

^§ p values were obtained from Wilcoxon signed rank test

Significance was accepted for p values of < 0.05
