Brief Summary:
People with Amyotrophic Lateral Sclerosis (ALS) will use a P300 based brain computer interface (BCI) keyboard to type in assistive technology devices. The results of this study will be compared with a previous study of a P300 BCI keyboard used by healthy volunteers.

Arm Intervention/treatment
Experimental: P300 Brain Computer Interface for people with ALS Device: P300 Brain Computer Interface Keyboard
Subjects will wear an EEG cap for 1-4 hours (1-2 hours typical) per session and use the brain-computer interface to operate assistive technology. Subjects will be asked to participate in 3 sessions.
Other Name: Electrode cap made by Electro-cap International.


Outcome Measures

Primary Outcome Measures :
  1. Accuracy of Typing With a BCI Keyboard by ALS Patients. [ Time Frame: 3 times over 2-4 weeks ]

    Accuracy for the sentence typed in each environment was calculated as the percentage of characters for which the result character matched the target character. The target characters were determined based on the next character needed to complete the sentence to be copied. In the case of errors, the next character was therefore a backspace to correct the error. The target characters were modified by subject comments to account for errors in selecting the next character.

    Once sentence was typed in each environment in each session on a separate day. From the three repeated sessions, there were therefore 9 total sentences per subject with 3 measures for each environment. These were treated as repeated measures for the analysis.
