MOVXAM is a human movement analysis system. With single camera recording, it provides digital and waveform presentation of human movement. Designed modules analyze movements of hand, foot, arm, leg and gait. It is an added tool of assessment of physical skill, movement mobility, agility and dexterity. 

The user manual consists of two categories: Video Recording Manual and Video Analysis Manual 

There are 33 Modules available to use: each module will illustrate movement picture, video recording techniques and methods of recording.

Setup for video recording:

Ideally you should use an Apple iPad Pro. Download the ProMovie Recorder app. Use this app to record videos. 

Zooming: For the iPad, place the movement recording overlay to the square exposure. 

Distance of Recording: please see each module requirement.

Hand Modules Introduction

Subject will be sitting in an arm adjustable chair, recording distance of 23-24 inches for hand modules. Face sideways to camera for all hand modules. Suggest finishing all left side modules, then change chair to opposite direction to perform right side modules. 

For the camera stand you should use a three-foot adjustable-height iPad stand.

Following is an illustration of the recording overlay.

On the bottom of the picture, you can see the Zoom and Focus scales.

1. Finger Tapping (LFIT/RFIT) Description

Subject sits sideways to camera, elbow rests on adjustable-height arm of the chair. Subject uses index finger tapping to the thumb, both thumb and index finger open away from each other with maximal degree and tapping close against each other with firm and stable tapping for 10 seconds. 

Start left hand first then move the chair to face to opposite side with right arm in the background. Right hand has the exact same performance as the left one. 

Good distance, around 2 feet.                                        A little too far; occupying four grid squares is ideal.

2.Finger-to-Nose (LITI/RITI) Description

Subject sits sideways to camera, pointing left index finger to the right index, distance height is around four inches. The left module will have right index as the base, with the left index finger moving from the nose to the right finger. Repeat the motion as fast and accurate as you can for 10 seconds. Then switching chair to opposite side, with left hand as the base, right index tapping from nose to left index. 

Do not record the person’s face.

3.Pointer-to-Pointer (LPTP/RPTP) Description

Subject sits sideways to camera, two index fingers tapping each other with two hands crossed holding each other, with the thumbs either tucked in or crossed (see the two following images). It the thumbs are crossed, then the motion will be more stable. Hold the hands together loosely with the index fingers straight out, left hand on top first, with pinky side of hand facing to background, right back of hand facing to the ground, left back of hand facing to ceiling. Then tap the index fingers together as fast and accurate as possible for 10 seconds. Moving chair to opposite direction, do right side with the same performance.

4.Hand Flapping (LHF/RHF) Description 

Subject sits sideways to the camera, resting the left elbow on arm of the chair. Start with left hand with five fingers opening then closing, like making a fist. The thumb should open as much as possible. Each hand open-close cycle should be precisely performed and pacing the speed as fast as you can for 10 seconds. The chair is then moved to the right side. Perform the same action with the right hand. 

5.Hand Supination and Pronation (LHPS/RHPS) Description 

Subject sits sideways to the camera, left arm straight out at a 90-degree angle to the shoulder. Start with moving left-hand supination then pronation. Be sure every cycle is in a precise position, pacing the speed as fast you can for 10 seconds. The chair will then be moved to the right side, with the right hand performing the same movements as the left hand did.
