Host Mesh Fitting of a Generic Musculoskeletal Model of the Lower Limbs to Subject-Specific Body Surface Data: A Validation Study

Table 1

Average normalized muscle-tendon lengths (%) derived from the subject-specific MR images (MRI) compared to the predicted values from HMF for the children without CP and the children with CP.

	Children without CP			Children with CP
	MRI	HMF	value	MRI	HMF	value
Soleus	71 (5.1)	71 (2.2)	>0.05	66 (4.7)	69 (2.3)	>0.05
Gastrocnemius	60 (5.8)	56 (3.6)	>0.05	51 (3.7)	55 (1.5)	<0.05
Biceps femoris	58 (4.6)	60 (1.7)	>0.05	54 (3.7)	56 (4.8)	>0.05
Semi group	82 (3.3)	84 (3.7)	>0.05	76 (7.2)	81 (3.7)	<0.01
Rectus femoris	76 (1.3)	79 (1.6)	<0.05	68 (3.1)	75 (2.9)	<0.01
Vasti group	91 (4.1)	91 (5.0)	>0.05	85 (2.1)	86 (2.7)	>0.05

Difference between MRI and HMF statistically significant (repeated measures ANOVA with Tukey-Kramer multiple Comparison post hoc test, ).
