Setting up your MotionSleeve

Welcome. This guide walks you through setting up your MotionSleeve — from opening the box, getting started, through your last session. If you hit a snag, check the troubleshooting guide or email us at hello@openmotion.ai and we’ll help you out.

Step 1 — Charging the MotionSleeve

When you open the box, you should find:

• The MotionSleeve — an upper and lower sensor pack connected by a flexible elastic conductive strap, secured to your limb by two adjustable elastic compression wraps, like an ACE bandage.
• USB-C charging cable — one cable charges the entire sensor pack.

Top up the MotionSleeve before your first session:

1. Connect the USB-C cable to the sensor pack’s charging port.
2. Plug the other end into a standard USB power source. A wall adapter (5V, 1A or higher) charges fastest.

A full charge takes about 90 minutes from empty. While it charges, download the KineticOS app on your phone (iOS or Android). You’ll be able to check the battery percentage in the app once you’ve paired with the sleeve (Step 3).

Step 2 — Put it on

Your MotionSleeve ships pre-configured for your prescribed joint — no setup needed. It wraps on like an ACE bandage, and attaches one of two ways depending on whether you’re rehabbing an upper or lower joint.

For shoulder or elbow rehab (upper body)

Each velcro tab comes pre-routed through its rectangular D-ring, forming a closed loop you slide your injured arm through. The D-ring acts as a friction cinch — pull the loose end of the velcro through, wrap it back over itself until snug, then press it flat to secure.

1. Lay the sleeve flat on the table, without attaching the velcro to the sleeve yet.
2. Slide your injured arm through both loops.
3. Lower the outside of your upper arm, near the middle of your tricep, onto the upper sensor pack — use your arm’s weight to hold the sensor against the table as you continue to cinch the wrap snug around your arm like an ACE wrap until secure, then press the velcro tab flat.
4. Position the lower sensor pack on top of your lower arm, like a wristwatch — a few inches above where a watch would sit. Cinch the wrap snug around your arm like an ACE wrap until secure, then press the velcro tab flat.

If sliding your injured arm through the loops isn’t possible — limited range of motion, post-op restrictions — the sleeve can also be attached the same way as the lower-body version: wrap each compression wrap around your arm individually and secure with the velcro. You may want or require assistance.

For hip or knee rehab (lower body)

The compression wraps go around your injured leg like an ACE bandage — wrap them snug enough that the sensors don’t slide during rehab exercises and secure them in place with the velcro tab. Sitting down makes this easier.

1. Sit down with your injured leg accessible.
2. Hold the upper sensor pack against the outside of your thigh, about a hand’s width above the knee. Wrap the strap around your thigh and secure the velcro.
3. Wrap the lower sensor pack into place on the outside of your lower leg, next to your calf.
4. Make sure each wrap is snug enough that it stays put during movement.

The wraps should fit snugly but not tightly — you should be able to slide one finger underneath the top edge of each one.

Step 3 — Open the app, pair, and calibrate

Once you’re wearing the MotionSleeve, open the KineticOS app. The device wakes with motion or when your phone is actively trying to connect — there’s no power button to press.

1. Tap Connect at the top of the screen.

   

2. The Connect Sleeve screen appears and scans for nearby sleeves — yours will show up as BGX____ (BGX followed by four characters), along with its signal strength. Select your device.

   

3. Your phone shows a Bluetooth Pairing Request — tap Pair.

   

4. Assign Location — select where the sleeve is worn (Left Leg, Right Leg, Left Arm, or Right Arm).

   

5. Posed Calibration — follow the on-screen instructions to position the sensors and face the direction you’ll be in during the activity. Hold the pose, then tap Calibrate Now.

   

6. When you see Calibration Complete — “The avatar should now mirror your limb movement” — tap Continue.

   

You’re paired and calibrated. The Connect pill at the top of the screen now shows your device ID in green.

Step 4 — Start your first session

From the home screen showing your prescribed protocol, tap Start Session. The app walks you through each activity:

1. Activity Prep — shows the exercise name, sets and reps, and a reference photo of the position. Tap Begin when you’re ready.

   

2. Position Prep — get into the starting position the app describes (e.g., “Sit upright in a chair with your feet flat on the floor”). When you’re in place, hold until the next screen.

   

3. Perform the activity — the avatar mirrors your movement, the dial shows your peak angle against the target, and the app counts your reps and sets automatically. Activities may be active ROM (you move the joint using your own muscles) or passive ROM (an external force — your other hand, a therapist, or equipment — moves the joint while your muscles stay relaxed), depending on what your care team prescribed. Tap Complete when you’ve finished the set.

   

4. Activity Summary — after each activity, add any notes for your care team and tap Submit to move on.

   

5. The app moves to the next activity. Continue until all activities are done.

After your last activity:

6. Summary — review activities completed and total duration. Tap Continue.

   

7. How did you feel? and Pain level? — rate the session. These go to your care team.

   

8. Tap End Session.

You’ll see “Great work! See you again soon!” — that’s it.

What to do if something goes wrong

• App won’t find the device: make sure Bluetooth is on and can discover new devices, and move the MotionSleeve closer to the phone. Make sure the device is charged. The sleeve wakes with motion or when the phone is actively trying to connect.
• App sees the device but fails to connect: the sleeve’s battery is probably low. Plug it in to charge, then try again.
• Problems putting on the MotionSleeve: contact us for help or an exchange at no cost.
• Anything else: see the full troubleshooting guide.
