Clinician Reference

  
Using ReclaiMove with Your Patient

  
A practical guide for clinicians running sessions — from hardware setup through to reading and exporting results.






  

    
Before the Session

    
Getting set up

    
You need the coordinator tile connected via USB and the bridge program running on your laptop.

    

      

        
1

        

          
Plug in the coordinator tile

          
Connect the coordinator (the main tile) to your laptop via USB. Place the other tiles within reach of the patient — one on the left, one on the right, to encourage full spatial scanning.

          Left-side tiles are activated more frequently by default to target left hemispace neglect.
        

      

      

        
2

        

          
Start the bridge program

          
Open a terminal and run node bridge.js --port COM5 (or your serial port). First-time setup: run node bridge.js --setup to generate a TLS certificate, then open https://localhost:8443/ in your browser.

        

      

      

        
3

        

          
Wait for tiles to bind

          
The coordinator will advertise a Zigbee network. Child tiles (the patient-side tiles) will join automatically. The sidebar will show each device turn green as it comes online.

          The coordinator opens the network for 180 seconds on boot. Power tiles on within that window.
        

      

      

        
4

        

          
Configure the session

          
Choose your mode (Reaction or Simon Says), set the difficulty, and pick the number of rounds. For new patients, start with Easy and 10 rounds.

          Easy = 10 s timeout · Medium = 5 s · Hard = 2 s
        

      

    

  


  


  

    
Game Modes

    
What the patient experiences

    
Both modes target spatial attention and upper-limb activation.

    

      

        
RT — Reaction

        
Reaction Mode

        
A tile LED lights up at random. The patient scans, locates the lit tile, and presses it. Reaction time is recorded in milliseconds from the hardware. Best for assessing spontaneous spatial scanning.

      

      

        
SQ — Simon Says

        
Simon Says Mode

        
Tiles activate in a sequence you configure. Use this when you want the patient to practice a specific scanning pattern — for example, left-to-right or across the midline.

      

    

  


  


  

    
During the Session

    
What happens round by round

    
The coordinator runs each round automatically. No manual timing needed.

    

      

        
1

        

          
A tile lights up

          
The coordinator selects a tile (random in Reaction mode, sequential in Simon mode) and turns its LED on via Zigbee. A 10-second countdown begins on the hardware.

        

      

      

        
2

        

          
Patient presses the tile

          
When pressed, the child tile turns its own light off (signalling the coordinator) and sends a Zigbee message. The coordinator records the elapsed time and the dashboard updates in real time.

        

      

      

        
3

        

          
Result is classified

          
Each response is automatically rated based on elapsed time and the active difficulty setting.

4

        

          
Repeat for all rounds

          
After a 1-second pause, the next round begins automatically. Charts and the session log update in real time. You can stop the session at any time with the Stop button.

        

      

    

  


  


  

    
Reading the Results

    
What the dashboard tells you

    
The four summary numbers at the top update after every round.

    

      

        
#

        
Rounds completed

        
Stimulus-response cycles completed this session. Confirms the patient finished the intended number of rounds.

      

      

        
ms

        
Average reaction time

        
Mean response time across successful presses. A lower average across sessions reflects improving spatial attention and motor speed.

      

      

        
PB

        
Best time

        
The fastest single response in the session. A useful motivational reference to share with patients at the end of a session.

      

      

        
MT

        
Missed rounds

        
Rounds with no press within the timeout. A high miss rate on left-side tiles may indicate left-side neglect severity.

      

    

  


  


  

    
FAQ

    
Common questions

    

      

        
The dashboard says "Not connected" even though the bridge is running.

        
The browser must open the dashboard via https://localhost:8443/ — not as a local file. If you see a certificate warning, accept it (it's self-signed). Check that the correct serial port is passed to bridge.js.

      

      

        
The coordinator is online but tiles show as Offline.

        
Power on the child tiles while the coordinator's Zigbee network is open (within 180 seconds of coordinator boot). If you miss the window, reboot the coordinator. The dashboard will show tiles as Online as they bind.

      

      

        
Why is there no simulation mode?

        
ReclaiMove is a clinical measurement tool. All reaction times come directly from the ESP32-H2 hardware to ensure accuracy. Simulated data could never represent real patient performance, so it has no place here.

      

      

        
How do I export session data?

        
Click "Export Encrypted CSV" in the session log, set a password, and download the .enc file. Use "Decrypt CSV" to read it back later. Exports are AES-256-GCM encrypted and never leave the local HTTPS connection.
