APDM OPAL User Manual

WELCOME

to Mobility Lab

Using APDM’s advanced wearable sensors, Mobility Lab makes it easy to collect, analyze, and store outcome measures. Attach sensors to your subject, and instruct them to perform a standardized test. A report is then automatically generated to compare against normative values.

The wireless Access Control Point allows for wireless communication between the host computer and Opal movement sensors. A single Access Point can support up to 6 Opals.

The Mobility Lab software supports the use of a remote control to aid while collecting data. This functionality makes it possible for a single attendant to collect data while following or assisting the subject.

TIPS

Storage

Hardware Cong

Setup M.L. How to

Hardware Cong

Parts

Setup M.L. How to

Hardware Cong

In most situations, it is sufficient to simply dock your sensors when not in use. When docked, sensors stop

recording, stop broadcasting, and charge batteries. Do not leave sensors docked in a docking station that is not

plugged into a power outlet.

For transport and storage, it is best to power off all system components. This can be done by docking the

sensors and clicking the “Power Off” button in the Mobility Lab menu. The sensors will power down the next time

they are undocked.

Cleaning

Clean the Opal sensors with a rubbing alcohol or other cleaning wipe. Do not use methyl alcohol, as it will cause

degradation of the plastic over time.

The sensors and other system components should not be submerged in any liquids or subjected to any high

temperatures.

The sensor straps can be removed and washed separately using mild soap and water.

Subject Attire

The subject should wear clothing that does not bind their movement in any significant way.

Walking shoes should be worn (i.e. no heels or flip-flops).
