This study was to analyze the performance of fixed-point adaptive signal enhancer (ASE) for somsatosensory evoked potential (SEP) measurement. An animal study was conducted to evaluate the usefulness of this technique in detection of spinal cord injury. The ASE technique has been reported powerful to improve signal to noise ratio of SEP. Therefore, we proposed an integrated circuit module to perform...
This paper aimed to design an EEG-based mouse system by using brain-computer interface (BCI) to move a cursor on a computer display. This system to provide an alternative communication or control channel for patients with severe motor disabilities. Such patients might become able to select target on a computer monitor by moving a cursor through mental activity. The user could move the cursor just...
This paper describes surface electromyogram (sEMG) recordings of the lumbar muscles during walking. The intent of these pilot trials was to evaluate the usefulness of the sEMG in differentiating between two groups of subjects: healthy subjects and those with lower back pain. An analysis of the features of the sEMG was performed for clearly defined walking activities for both subject groups. The results...
The objective of this study was to analyze the performance of fixed-point adaptive noise canceller (ANC) for SEP measurement, as well as compare with the outputs of floating-point ANC at 16 bits word-length. ANC technique has been reported powerful to improve signal to noise ratio (SNR) of somsatosensory evoked potential (SEP). For the sake of real-time monitoring of intraoperative SEP, both fixed-point...
