1 Introduction to the Actiwatch System 1.1
An Overview of the Actiwatch System
The Actiwatch is a compact and lightweight electronic device that measures and records physical movement. Worn on the non-dominant wrist for sleep or activity analysis and on the feet for Periodic Limb Movements in Sleep (PLMS) analysis, the Actiwatch can be worn for long periods of time by subjects of all ages and any health status. Depending on the model selected, the Actiwatch is available as a fully waterproof unit with a battery life of up to 8 years continuous usage. Models of Actiwatch are available that record the following: • • • • •
Physical activity (can be used to measure sleep quality with the Actiwatch Sleep Software) PLMS (when mounted on the feet and used with the relevant software) Light (if a compatible Actiwatch model is selected) Activity & subjective patient input (Actiwatch Score – detailed in a separate manual) Tremor (Tremorwatch - detailed in a separate manual)
The Actiwatch collects movement data which is stored in the non volatile memory and is then transferred to the PC using CamNtech’s proprietary telemetric reader/interface. The movement data can then be analysed using the relevant software package. Details on the models of Actiwatch and analysis software packages available can be found in section 1.3.2 of the Guide to Getting Started. Further details on how the Actiwatch system works can be found in section 1.4 of the Guide to Getting Started. 1.2

The Actiwatch Range 1.3.1
The Actiwatch Range – Hardware
The Actiwatch range consists of the following models: •
Actiwatch AW7
The Actiwatch AW7 was launched in 2007 and extended the functionality and practicality of the Actiwatch range. With a battery life of 8 years continuous use, activity marker button and recording time of up to 180 days with a 1 minute epoch, it is also the most highly specified Actiwatch in the range. The AW7 has been pressure tested to 6 Bar and is suitable to be worn whilst swimming. •
Actiwatch AW4
The Actiwatch AW4 is the predecessor to the Actiwatch AW7. It has been used extensively by researchers, clinicians and in clinical trials. It offers a recording time of up to 45 days with a 1 minute epoch. •
Actiwatch Mini
The Actiwatch Mini is designed for applications where weight or size is important. It is ideal for paediatric use. Weighing only 7.5 grams it is the lightest actigraph on the market. It can be supplied for either wrist mounting or neck mounting. •
Actiwatch Light
The Actiwatch Light allows the monitoring of ambient light levels as well as the measurement of activity. It is ideal for circadian rhythm studies or any application that requires light monitoring. The light sensor is integral to the watch and is provided in place of the marker button. •
ActiLight (External light sensor for use with the Actiwatch Mini/AW4/AW7)
Actiwatch Guide to Getting Started 7.2
Page 5
The ActiLight is a separate light sensor for use with an Actiwatch. Light data is recorded for up to 45 days (at a 1 minute epoch) and can then be combined with activity data. This unit is housed in a similar case to the Actiwatch Mini so is extremely light. It has the advantage that the unit can be worn either attached to the clothing or on a neck chain so can be kept clear of clothing or bedding when used for recording night time light levels. A table showing the specifications of each model is shown on the following page: Full technical specifications of all models are contained in the technical appendix of the Actiwatch Manual. 1.3.2

Actiwatch Technical Overview
Accelerometer Orientation
Accelerometer is Most Sensitive to Motion in this Direction Actiwatch
Actiwatch activity is measured in counts. This is a term used to denote the amplitude of the signal produced by the accelerometer in the Actiwatch. The number of counts is proportional to the intensity of the movement. The accelerometer in the watch checks or samples the amplitude of the movement thirty two times per second and it captures the highest amplitude in that second. This represents the peak intensity of the movement in that second. The peak intensity values are summed into a user selectable epoch (epoch range between 2 seconds and 15 minutes depending on the model of Actiwatch used). Activity values can be viewed in counts per epoch in the software or exported and viewed in Microsoft Excel. Full technical details on the operation of the Actiwatch can be found in the appendices of the Actiwatch User Manual.
