Tremor is a periodic oscillation phenomenon that involuntarily occurs in a range of anatomical units. It has been well known that central nervous system (CNS) factors are important determiners of tremor. The present study on tremor associated with Alzhiemer are important from a clinical perspective because tremor analysis technique have been advocated as a sensitive clinical tool to determine the onset of neurological diseases. Thus, the purpose of the present study was to investigate the characteristics of wrist tremor to develope a diagnostic system of Alzheimer‘s disease through the measurement and analysis of tremor. The wrist tremors were measured from 30 Alzheimer patients and 30 normal people by using an accelrometry. The time domain and frequency properties of the wrist tremor acceleration signals were compared between the two groups by performing a power spectrum density analysis on the acceleration time-series for each trial. The frequency domain analysis on the wrist tremor showed that the Alzheimer patients and normal elderly revealed the similar modal frequency in 1-6 ㎐, 7-15 ㎐, and 1-15 ㎐ frequency bandwidths. However, in the time domain analysis the Alzheimer patients revealed the significantly less degree of the acceleration than the normal elderly. These results suggest that for more accurate differentiation between two groups the time domain analysis is appropriate for the tremor of the proximal segments while the frequency domain analysis is recommended for the tremor of the distal segments.
