Established principles
Progressive exercise, motor learning, task-specific practice, dosage, recovery, and outcome measurement are established rehabilitation concepts.

Evidence with context
Built on rehabilitation science. Clear about the evidence gap.
ISO Metrik distinguishes established rehabilitation principles, the broader facial-therapy literature, product-development work, and evidence that must still be generated for the device itself.
Evidence framework
Four distinct levels of support.
Keeping these levels separate prevents general rehabilitation science from being presented as proof of a device-specific result.
Related clinical literature
Published facial exercise and neuromuscular rehabilitation studies inform clinical questions, but interventions and patient groups vary.
Product development
Mechanical design, component testing, ergonomics, fit, usability, sanitation, and human-factors work inform the platform and training.
Device-specific validation
Prospective studies are needed to quantify ISO Metrik safety, feasibility, dosage, comparative outcomes, patient selection, and durability.
What related research can tell us
Use the literature without overstating it.
Exercise may support recovery
Systematic-review evidence suggests tailored facial exercise therapy can improve facial function in some facial palsy populations.
Outcomes should be multidimensional
Published work supports combining clinician-rated facial function with patient-reported outcomes rather than relying on appearance alone.
Interventions are heterogeneous
Studies vary in diagnosis, onset, severity, exercise method, supervision, dosage, comparator, and outcome measure.
Timing remains individualized
The literature does not establish one universal start time, resistance level, dosage, or progression sequence for every patient.
Device effects cannot be assumed
Evidence for facial exercise generally does not establish that ISO Metrik produces the same effect or treats a particular condition.
Safety requires active study
Device-specific research should capture oral, dental, jaw, tissue, neurological, swallowing, and other adverse responses.
Research priorities
Questions the clinical program should answer.
Relevant study domains include feasibility, safety, usability, adherence, strength, endurance, symmetry, selective movement, oral seal, patient-reported function, speech and swallowing measures within scope, and durability of change.
Research should define the patient population, recovery stage, comparator, provider training, device configuration, dosage, progression rules, outcome timing, missing-data plan, and adverse-event process before enrollment begins.
Priority research questions
Build the evidence in a logical sequence.
Feasibility
Can trained providers screen, fit, prescribe, document, and monitor the platform consistently in real clinical settings?
Safety and tolerability
What adverse events, discomfort, dental or jaw issues, tissue responses, fatigue, or symptom changes occur, and in whom?
Dose finding
Which resistance, frequency, volume, hold time, tempo, and progression rules are tolerable and potentially useful for defined populations?
Clinical signal
Do prespecified facial, oral-motor, functional, and patient-reported outcomes change beyond expected variability?
Comparative effectiveness
How does the platform compare with usual care, another active intervention, or a clearly defined control condition?
Durability and implementation
Are changes maintained, what supports adherence, and what clinic resources are required for safe delivery?
Study development
Move from feasibility to stronger clinical evidence.
Define intended use
Specify the target population, functional problem, setting, provider, device configuration, and proposed claims.
Complete preclinical and human-factors work
Evaluate mechanical performance, materials, biocompatibility needs, cleaning, usability, fit, and foreseeable use errors.
Conduct feasibility research
Test recruitment, screening, training, adherence, data collection, tolerance, and protocol fidelity in a limited sample.
Refine the protocol
Use prespecified criteria to address safety signals, inconsistent delivery, burden, missing data, and outcome sensitivity.
Run prospective comparative studies
Use appropriate controls, blinded assessment when possible, registered methods, adequate follow-up, and transparent reporting.
Translate responsibly
Align labeling, training, marketing, and clinical implementation with the evidence and applicable regulatory authorization.
Research quality
Protect participants and the credibility of the findings.
Ethics and consent
Use appropriate institutional review, informed consent, privacy protections, and special safeguards for vulnerable participants.
Prespecified methods
Register the protocol and define primary outcomes, analysis, subgroups, missing data, and stopping rules before results are known.
Representative enrollment
Report diagnosis, onset, severity, age, comorbidities, and exclusions so readers can judge generalizability.
Standardized delivery
Train providers, document fidelity, and record device setup and dosage so the intervention can be reproduced.
Complete safety reporting
Capture expected and unexpected events, severity, relatedness, action taken, resolution, and withdrawals.
Transparent publication
Report favorable, neutral, and unfavorable results; disclose funding, conflicts, protocol changes, and limitations.
