Abstract—The main objective of the study is to obtain the comparison of the frequency band energies in gait signals ALS (Amyotrophic Lateral Sclerosis), PD (Parkinson Disease), HD (Huntington Disease) and healthy subjects. The gait signals are decomposed into approximation and details by using DWT and the energy values of them are calculated. The D3, D4, D5 details are determined as critical features according to energy percentages. Consequently, the study demonstrates that proposed method makes easily ALS discrimination of other neurodegenerative diseases and control subjects possible.
