# Codebook: FDA reports on powered exoskeletons, powered arm prostheses, stair-climbing wheelchairs and all-terrain wheelchairs

Written before any report in the set was coded. Mobility Atlas study, October 2026.

## Pool
Every FDA MAUDE device report with text filed under product code PHL (Powered Exoskeleton), IQZ (Hand, External Limb Component, Powered), PAE (Upper Extremity Prosthesis With Multiple Simultaneous Degrees Of Freedom And Controlled Via Cutaneous Electromyography), IQW (Hook, External Limb Component, Powered), IRE (Joint, Elbow, External Limb Component, Powered) or IMK (Wheelchair, Stair Climbing), received at any date up to the latest openFDA update read on 18 October 2026; plus every report already read for earlier Mobility Atlas studies under IOR (manual wheelchairs, 2019 to 2026) or ITI (powered wheelchairs, 2024 to 2026) whose text names an all-terrain, off-road, beach, tracked or trail chair.

## What you record for each report
One line per report: `report_key,device,problem,injury,fall,setting,finding,note`

### DEVICE (one letter)
- E: POWERED EXOSKELETON (ReWalk, Ekso, Indego, Wandercraft Atalante, any powered leg exoskeleton).
- A: POWERED ARM, HAND, HOOK OR ELBOW PROSTHESIS (myoelectric hand or arm, LUKE arm, i-Limb, bebionic, powered hook).
- S: STAIR-CLIMBING WHEELCHAIR (iBOT, a tracked stair-climber, any chair that climbs stairs).
- T: ALL-TERRAIN, OFF-ROAD, BEACH OR TRACKED WHEELCHAIR that is not used on stairs in the report.
- O: another device (an ordinary wheelchair or scooter, a leg prosthesis, an orthosis) — the event is not about one of the above.

### PROBLEM (one letter): what went wrong first, as the report alleges. If several, take the first in this list.
- F: FALL OR TIP WITH A DEVICE FAULT ALLEGED (the device stopped, moved or tilted unexpectedly and the user fell or the chair tipped).
- B: BATTERY, CHARGER OR POWER (would not charge, ran flat, overheated, smoke, fire).
- C: CONTROL, SENSOR, SOFTWARE OR ERROR (unexpected movement, error code, app, joystick, EMG signal, mode change, stopped responding).
- M: MOTOR, GEARBOX OR DRIVE (motor failed, noise, track or wheel drive).
- S: STRUCTURE (frame, strap bracket, finger, hand shell, joint, track, wheel broke or came loose).
- K: SKIN OR FIT (pressure sore, abrasion, bruise from straps or socket, burn, poor fit) with no other fault.
- U: USE OR TRAINING (fall or injury during use or training with no device fault alleged, wrong use).
- Q: problem alleged but not described.
- X: no device problem described.
- N: no event (use with DEVICE N).

### FLAGS (y or n)
- injury: harm to the body or medical care is stated (pain counts). y when the event type is Death.
- fall: the user fell, the user went to the ground, or the chair tipped over with the user.

### SETTING (one letter): H home or community, C clinic, hospital or rehab centre (including therapy sessions and trials), U unclear.
