Ask about candidacy The movement goal
Explore whether powered elbow assistance can support the patient’s individual activity goals when they cannot move the arm independently.
WHO IS UBILIFLEX™ FOR?
The arm may be paralyzed.
The control signal
may come from elsewhere.
UbiliFlex™ is available now. People with complete paralysis of the affected arm, including wheelchair users, may be evaluated when they retain a potentially usable voluntary muscle signal elsewhere.
Ask if you may be a candidate01 / LOOKING BEYOND THE ARM
A different muscle.
A movement request.
The muscle providing the command does not have to be the muscle moving the affected arm.
UbiliFlex™ uses a surface electromyography sensor, or sEMG sensor, to detect intentional muscle activity. That signal becomes a movement request; the controller commands the powered elbow mechanism.
When the arm has no voluntary movement, evaluation can explore whether a muscle elsewhere provides a usable signal. The aim is to use the voluntary control the patient retains, rather than require movement from the paralyzed arm itself.
A voluntary contraction is a starting point, not automatic eligibility. The team must establish that a suitable site produces a detectable, repeatable signal and that the patient can intentionally activate and relax it without unacceptable unintended triggering.
ONE INTEGRATED BRACE SYSTEM
A personal fit.
A signal you control.
The brace, battery, and surface-EMG sensor form part of the integrated system. Your evaluation considers both the physical fit and your ability to produce a usable control signal.
Contact the Ubility™ team03 / CONDITIONS TO DISCUSS WITH YOUR CLINICIAN
A diagnosis begins
the conversation.
It does not decide the fit.
Patients with arm paralysis associated with ALS, stroke, or spinal cord injury may contact Ubility™ about an evaluation. A usable muscle signal, an appropriate physical fit, and individual clinical assessment are required; a diagnosis alone does not establish suitability or guarantee benefit.
ALS
For a person with ALS and severe arm weakness or paralysis, the evaluation question is whether a remaining voluntary muscle signal can provide usable control and whether the overall setup is appropriate.
Clinical review should consider current function, fatigue, support needs, and whether changing needs require reassessment.
Stroke
For a person with arm weakness or paralysis after stroke, evaluation focuses on the available control signal, the affected arm’s movement limitations, and the activities the patient wants to work toward.
The team assesses the person’s ability to use the control method and tolerate the fitted brace rather than relying on the diagnosis alone.
Spinal cord injury
For a person with spinal cord injury, including a wheelchair user with complete arm paralysis, evaluation can consider retained voluntary muscle activity outside the affected arm.
Signal control, seated positioning, arm support, fit, and the overall clinical picture determine whether a trial is appropriate.
04 / PRELIMINARY EXPERIENCE
Exploring control
beyond the arm.
Dr. Ajay Seth reports that preliminary UbiliFlex™ work included a patient with ALS using neck and facial muscle activity as control inputs.
This is an early observation reported by the developer, not evidence of effectiveness across patients with ALS. Study methods, participant numbers, outcomes, and safety findings are not presented here. Alternative control sites require individual assessment.
05 / BEFORE A PATIENT-SPECIFIC BUILD
Assess the signal.
Assess the person.
A usable muscle signal is only one part of the decision. Your clinical team evaluates the complete picture before proceeding.
- 01
Goals & clinical review
Discuss the patient’s condition, arm function, everyday priorities, and clinical factors relevant to a powered brace.
- 02
Voluntary signal assessment
Identify a potentially suitable muscle site and assess detection, intentional activation and relaxation, repeatability, fatigue, and unintended signals.
- 03
Physical fit & seated positioning
Review available arm motion, comfort, skin contact, alignment, support, and the space needed for the device and the intended activity.
- 04
Training & support needs
Consider how the patient will learn the control method, how the brace will be put on and removed, and what caregiver or clinical support is needed.
06 / THE PATIENT-SPECIFIC FABRICATION JOURNEY
From evaluation
to your individual brace.
The custom-fabrication pathway begins after clinical and signal assessment supports proceeding. This flowchart explains the build process; it is not an eligibility test or a promise of delivery.
- 01
Prescription & functional evaluation
Document the individual’s needs and the clinical decision to proceed.
- 02
3D limb scan & direct measurements
Capture the patient-specific anatomical inputs.
- 03
Patient-specific digital limb model
Review and refine the model for custom design.
- 04
Custom fabricated cuff and bracket design
Determine the geometry and clearance needed for the individual interfaces, liner, and assembly.
- 05
Thermoplastic interfaces molded to the patient
Shape the patient-contact interfaces for the individual arm.
- 06
Patient-specific component fabrication
3D print cuff shells and fabricate the custom connecting parts.
- 07
Finishing, liners & assembly
Finish the components, make the patient-sized liners, and assemble with the powered hardware.
- 08
Alignment, sensor calibration & programming
Set up the assembled brace and the assessed control signal for the patient.
- 09
Final fitting, verification & training
Complete the required checks and guided training before delivery, where appropriate.
START WITH YOUR QUESTIONS
Your goals matter.
Your evaluation is individual.
Ask your clinician whether powered arm assistance and an alternative muscle-control site are worth evaluating for your situation. This page is general information, not a diagnosis or an individual eligibility decision.
