Effects of Mouse Tremor Smoothing Adapter on Ease of Computer Mouse Use by Individuals with Essential Tremor: A Pilot Study
As many as 10 million people in the United States are diagnosed with a complex neurological movement disorder called Essential Tremor (ET), with many more worldwide . ET is a condition that is particularly troublesome during the use of computer programs that require good mouse control. The purpose of this study was to determine whether hardware and software versions of a smoothing filter labeled the Tremor Control Mouse (TCM) could provide short- and/or long-term benefits for individuals who have difficulty using a computer because of ET of the hands. A paired-samples t-test revealed significant differences (p<.05) between participants’ responses to ease-of-use questions regarding traditional mouse use compared to TCM use. Subjective responses to survey items on TCM advantages, disadvantages, and helpfulness were very positive overall and reflected the participants’ belief that the TCM was a useful device in enhancing mouse control and, consequently, computer use.
