T scores, z scores and BMD values were also estimated from DXA results. According to the WHO classification system, the participants were classified as normal, osteopenic, or osteoporotic based on T and Z scores [ 3 ].
Hip and lumbar DXA BMD results were separately analyzed and were classified accordingly as normal, osteopenic or osteoporotic (T-score ≥ -1 normal, -1 > T-score > -2

done using the customised algorithm developed by Aristovich et al. [ 36 ] for neural activity imaging. The reconstruction method used linear single step Gauss-Newton approach (time difference and weighted frequency difference) with a Zeroth order Tikhonov regularisation [ 43 ] and subsequent coefficient-of-variance representation (z-score) with respect to the background noise. The algorithm is based on the assumptions that the conductivity change is small and all pixels are equivalent in terms of noise contribution to the resulting conductivity image. Random Gaussian

of felt pain strength is a key factor for successful pain management during surgery and other clinical procedures. Presently, most of the pain scoring systems used in clinical practice rely on patient cooperation and attentiveness. However, in some cases, for example in unconscious, confused, uncooperative patients, or in the case for infants, questioning is impossible. As a result, pain is usually poorly evaluated and inadequately managed. Therefore, a more practical, patient-independent method for this purpose is highly desirable. As pain provokes a sympathetic

Some studies have reported that BMI underestimates obesity in individuals with SCI [ 1 , 4 , 5 , 10 , 12 ]. This was also observed in the present study. Tetraplegic inactive group showed BMI˂25 kg/m 2 , which is considered normal, and fat percentage higher than 20%, indicating obesity. WHO reports that men with BMI≥30 kg/m 2 exhibit fat percentage ≥25%. However, this was not observed in this research, as in Jones et al (2003) study, that compared DXA with BMI in men with SCI and scored normal BMI results with high fat percentages.

To provide a qualitative comparison of each modality's reflection of CBF AR during each test, results were entered into a spreadsheet (Microsoft Excel, Redmond, WA), where assessment scores of successful and failed tests were recorded ( Table 2 ).
