BIOELECTRICAL IMPEDANCE ANALYSIS FOR BODY COMPOSITION ASSESSMENT OF SPINAL CORD INJURY SUBJECT: A CASE REPORT T.Y. Chiu1 , Y.A. Tsai3 and J.J.Chen1, 2 1 Institute and Faculty of Physical Therapy and Exercise and Assistive Technology of National Yang-Ming University, 2 Yang-Ming Exercise Health Science Institute, 3 Center of Neuron Regeneration of Taipei Veteran General Hospital; email:[email protected] INTRODUCTION The body composition of subjects with Spinal Cord Injury RESULTS AND DISCUSSION The assessment took 15 minutes to finish for one subject and (SCI) has been found different from others without SCI due subjects had no any uncomfortable feeling during the testing to injury itself, inactive lifestyle and change of diet. The period. The total body composition was listed in table1. The change of body composition was highly associated with BMI and WHR were in the normal range though the total diabetes, osteoprolosis, and cardiovascular diseases. The muscle mass and bone mass were less than subject without bioelectrical impedance analysis (BIA) is a noninvasive, SCI. The BMI and WHR often used to estimate the obesity rapid, safe, portable, reproducible, electrical method of but it may underestimate body fat in our subject. Jones et al. assessing body composition which was widely used in health has the same finding in their study of 19 SCIs. people. It has good validity in estimating limb muscle volume and predicting trunk muscle volume. However, the Maggioni et al found that the percentage of bone mass has BIA applying on SCI subjects has not been studied. The aim only difference in lower limb therefore no difference in total of this study was to evaluate the applicability of BIA in body. However, the percentage of bone mass in total body assessing body composition of SCI. was less in our subject. This different result may cause by the higher injury level (C5 vs. T5-L1) and lesser voluntary METHODS movement of our subject. A 41-year-old male SCI patient and a healthy subject with matched BMI were volunteer to our pilot study. The patient The estimation of limb muscle mass was listed in table2. was a C5 level and ASIA level C SCI case caused by traffic The muscle mass of lower limb were less then healthy accident on 2000. Total lamiectomy of C3-6 & removal of subject and this was same as previous studies. The decreased archnoid cyst and nerve repaired were done on 2001.

Body weight (BW) was measured to the nearest 0.1 kg on a calibrated electric scale. The circumference of waist and hip CONCLUSIONS were measured to the nearest 0.1 cm by a calibrated scale. The BIA system seems to be an applicable method to assess Body high (BH) was self-reported (pre-injury). Therefore the body composition of SCI.
