ACTIVPAl PAL Technologies Ltd  活动观测仪

The activPAL™ is lightweight (15g) and only 7mm thick.

• weighs only 15 grams
• 53 x 35 x 7 mm
• 7+ day recording period
•  

Using proprietary algorithms, (Inligent Activity Classification™), it classifies an individual's free-living activity into periods spent sitting, standing and walking. This information can be used to estimate daily energy expenditure and changes in the free-living activity profile can be tracked against medication or treatment regimes.

The activPAL™ is worn discrey on the thigh (see illustration).

PALstickies™ are the recommended attachment method for waking day recordings. The `stickiesemploy a patented dual layer hydrogel to provide optimum skin adhesion on one surface and device adhesion on the other. The dual layer gel allows the skin contact side to conform to the skin surface and provides adhesion without requiring the skin surface to be shaved or abraded.The multi-stick property of the `stickies allows them to be removed and repositioned on the skin on multiple occasions.

For continous wear the activPAL™ can be waterproofed by wrapping with a medical grade adhesive covering (e.g. 3M Tegaderm or S&N Opsite flexifix) and then attached to the thigh using another sheet of dressing. This attachment, subject to daily review, can provide 3-7 days continuous wear, allowing the wearer to shower without removing the activPAL™.

The activPAL™ is capable of recording for in excess of seven days continuously. The stored activity profile is retrieved and processed using a PC. Some results from previous studies are given in the examples section of this website.

An sample screen shot is displayed below:

This example profile is from a 65 year old woman:

• Between 4 and 5PM she takes a walk and then begins to prepare the evening meal.
• The meal is served shortly after 6PM and she serves dessert around 6:40PM.
• After 7PM she clears the meal away and retires to the sitting room.

The waking day recording for both her and her husband can be found on the examples page.

The activPAL™ has been designed for healthcare researchers and other professional users who have a requirement to measure free-living activity.
