• OBJECTIVES: Cervical spinal cord injury (SCI) causes severe dysfunction in daily life. The aim of this study was to assess site-related differences in muscle loss in people after complete cervical SCI. SUBJECTS: Eight men with cervical SCI (age ; 34.1 ± 2.4yr, height ; 172.9 ± 2.0cm, waist circumference ; 81.4 ± 2.8cm, SCI level ; C6 complete) and eight sex-, age-, height-, waist circumference-matched non-injured controls. MEASUREMENTS: Fat and muscle thicknesses at nine sites, forearm, upper arm anterior and posterior, abdomen, subscapular, thigh anterior and posterior, and lower leg anterior and posterior, were determined using brightness-mode ultra-sonography. Segment lengths and circumferences were also measured using anthropometry. RESULTS: There were no significant differences in limb lengths and fat thicknesses at nine sites between the subjects with cervical SCI and control group. The thickness of the upper arm anterior muscle, which could be contracted voluntarily in the subjects with cervical SCI, was also not significantly different between groups. In contrast, the muscle thicknesses in the forearm, posterior upper arm and four leg sites and limb circumferences were significantly smaller in the subjects with cervical SCI than in control group. Percent differences of muscle thickness between subjects with cervical SCI and controls were larger in the forearm (43.1%), upper arm posterior (45.9%), thigh posterior (45.8%), and lower leg posterior (56.2%) than in the thigh anterior (30.6%), lower leg anterior (29.7%), abdomen (25.7%), and subscapular (28.3%). DISCUSSION and CONCLUSION: Muscle atrophy after cervical SCI was less in the abdomen and leg anterior muscles than leg posterior muscles. The decrease rate of muscle thickness was not greater in the legs than in the lateral forearms and posterior upper arms, except for the posterior lower legs.
