REDCap module: Image Map

This REDCap module replaces an input, radio, or checkbox field with an image that users can interact with to select one or more options. Specific applications include a body map (with over 70 body regions), a smile scale from 1-7 with facial expressions, three representations of teeth and teeth surfaces, among others. See below for a complete list of current imagemaps. Future versions will allow admins and users to add additional maps via the module configuration. The module is tied to questions via the @IMAGEMAP action tag and the name of one of the pre-defined image maps. e.g. @IMAGEMAP=PAINMAP_FEMALE.

Prerequisites

• REDCap >= 8.0.3 (for versions < 8.0.3, REDCap Modules is required).

Easy Installation

• Obtain this module from the Consortium REDCap Repo from the control center.

Manual Installation

• Clone this repo into <redcap-root>/modules/imagemap_v0.0.0.
• Go to Control Center > External Modules and enable Image Map.
• To activate this module for a particular project, go to the project home page, click on the External Modules link, and then enable Image Map for that project.

Features included

This module defines a new action tag: @IMAGEMAP. The possible values for this tag are:

PAINMAP_MALE

Representation of a generic male body.

PAINMAP_FEMALE

Representation of a generic female body.

SMILE_SCALE

5_FACE_PAINMAP

SINGLE_TOOTH

TEETH_SURFACE

TEETH

PI-RADS

RHEUMATOID_MAN

The Rheumatoid man imagemap tool reflects disease activity and progression by recording joint involvement. It was designed for use in paediatric rheumatology, but can be used wherever joint mapping is required. The Rheumatoid man is in anatomical position, which means a frontal depiction, but not mirrored, i.e., the left hand would be depicted on the right side of the screen.

VA_CHART

A 2-D emotion wheel representation of the circumplex model of affect.

MBODY

Michigan Body Map (MBM) reflects body areas where chronic pain may be experienced.

BEES (BONUS)

DO_TOUCH_NET_BODY_COLOUR and DO_TOUCH_NET_BODY_GREY

DO-Touch.NET body region image map designed for use in osteopathic manipulative medicine (OMM) research.

66SWOLLEN_68TENDER_JOINT_COUNT

The 66 Swollen / 68 Tender Joint Count can be used to record the number of tender and swollen joints in patients with inflammatory arthritis e.g. psoriatic arthritis, rheumatoid arthritis. These counts can be used in calculated fields to generate disease activity scores in combination with other variables e.g. DAPSA, DAS28 scores.

Usage

To display one of the images above in a survey or data entry form, add a new field of type Text Box and include one of the following options in the Action Tags / Field Annotation (optional) field:

@IMAGEMAP=PAINMAP_MALE
@IMAGEMAP=PAINMAP_FEMALE
@IMAGEMAP=SMILE_SCALE
@IMAGEMAP=5_FACE_PAINMAP
@IMAGEMAP=SINGLE_TOOTH
@IMAGEMAP=TEETH_SURFACE
@IMAGEMAP=TEETH
@IMAGEMAP=PIRADS
@IMAGEMAP=RHEUMATOID_MAN
@IMAGEMAP=VA_CHART
@IMAGEMAP=MBODY
@IMAGEMAP=BEES
@IMAGEMAP=DO_TOUCH_NET_BODY_COLOUR
@IMAGEMAP=DO_TOUCH_NET_BODY_GREY
@IMAGEMAP=66SWOLLEN_68TENDER_JOINT_COUNT

Each region of an image is associated with a key, for example, the "Ankle (front-left)" of the female body diagram is linked to the key "f34". To find a particular key for a body part, please refer to the HTML files (map files) located in the folder maps. After selecting multiple body parts, the field containing the action tag @IMAGEMAP will have as a value a string of comma-separated keys, e.g. "f36,f17,f18,f21". Similarly, if using the faces diagram, the field containing the action tag (e.g. @IMAGEMAP=SMILE_SCALE) will have the value corresponding to the face clicked.

Testing instrument

This project includes an [Example Instrument](docs/Instrument\ Example.zip) that includes each of these image maps. It demonstrates different methods of using these image maps; which is suitable for testing or demonstration purposes.
