Donna Everett, of the 9900 block of Cervidae Lane, was arrested after her employer, Emerge, Inc., brought the video to the attention of police after discovering it on the website YouTube, police said.
Everett is also "seen and heard taunting and encouraging a female resident with disabilities to assist in the abuse of the man," police said.
Police have charged Everett with multiple counts of assault for allegedly abusing the 53-year-old disabled man and with endangering the 41-year-old disabled woman, police said.
Police are working to identify other people in the video. Those recording it can be heard laughing, police said.
Everett posted a $100,000 bond and has been released from the Howard County Detention Center, police said.
