The purpose of this study was to determine the effects of subcutaneous tissue thickness on NMES intensity and NMES force production of the quadriceps. Subjects: Forty three healthy subjects volunteered for the study. Subjects were placed into three groups dependent on tissue thickness measurements. Procedures: Knee extensor MVIC was measured with a Kin-Com™ Dynamometer and subjects became familiar with NMES using the OrthoDx™. A two way ANOVA with the factors of gender (male and females) and skinfold groups (category 1-3) was used to examine differences in the dependent variables of final NMES intensity and NMES force production. Results: For the dependent variable of final NMES intensity, there was a significant main effect for gender F(l,37) = .4.46, p=.042. Males exhibited a greater final intensity compared to females. A gender by skinfold category interaction was significant F(2,37) = 3.1, p=.05. Post hoc testing revealed that for skinfold category one, males were significantly greater than females (p=.001) and significant difference was found between skinfold category 1 and 3 (p=.005) within the females. Conclusion: When NMES intensity increased, NMES force production decreased. In addition, as thickness of subcutaneous tissue increased, the intensity of NMES increased.
