Treadmill Training Report

Treadmill training contains many advantages. Olivier Alluin et al. studied the effect of treadmill training with perineal stimulation with locomotor enhancement in complete thoracic SCI rat and compared the results between the trained and untrained rats \cite{alluin2015}. They found that treadmill training enhances spatial characteristics (step length, step cycle, maximum paw height during swing phase, paw lift and contact position relative to the hip) of step cycle. The step cycle length of trained rats was obviously greater than untrained rats since the 2nd week after SCI. The coefficient of variation (CV) of step cycle length indicates the capability of the rat to sustain a constant step cycle length during the locomotion. The step length

Even though the velocity of the limb extension part of the swing phase was still defective in both groups at week 10 after SCI, but it was gradually improved since week 5 in trained group. In trained group, the averaged velocity of the whole swing phase returned to similar value to the baseline since week 3 after SCI and it completely gained back at week 10 after SCI. Moreover, the enhancement of swing phase component relationship of treadmill training was shown from this study. The relationship between a parameter or dependent variable which was swing phase duration and its constituents or independent variables which were swing phase height, length, and velocity was explored by the polynomial multiple regressions in trained, untrained and normal rats at week 10 after SCI. The correlation of the normal rats was equivalent to 0.93 which showed the reliability to predict the swing duration by the swing phase height, length, and velocity. In trained rats, the correlation of these variables was 0.78. In the same way, the fitting hyperplane performed similar to the position and orientation as in normal
