Kinesia Hardware
The Kinesia movement disorders assessment system consists of two small lightweight components connected with a thin flexible cable that are worn on the finger and wrist of the patient.
The Wrist Module, the larger of the two, is worn on an adjustable band and contains a radio for wireless data transmission to a PC up to 100 feet line of sight, memory card for storing up to 50 hours of data and rechargeable battery lasting 8 hours. Two LEDs on the front of the module illuminate to indicate power and battery charging. A connector provides EMG inputs using a cable that is included with the system, allowing the user to monitor two channels of electrical muscle activity. The connector also serves as the connection point for data download and erase and battery recharging, which is done through a computer using a USB cable provided with the system. A push button patient diary on the front of the unit can be used by the patient to indicate when medication was taken and severe symptom episodes occur.
The Finger Sensor, the smaller of the two components, is worn on the finger using an adjustable Velcro strap and houses the motion sensing portion of the device. Three wireless orthogonal accelerometers and three orthogonal gyroscopes provide linear acceleration along and angular velocity about the X, Y and Z axes, providing a complete picture of the patient’s three dimensional motions. Data from the wireless accelerometers and gyroscopes is analyzed within the software to automatically score patient motor symptoms.
The use of wireless technology is continually increasing in the medical field and the wireless design of Kinesia offers several advantages over other types of tethered systems. Patients have the ability to move freely while wearing the device and patient safety is increased by eliminating obtrusive wires or connection to a computer or power outlet.
