The objective proof behind medical necessity — and more evals per week.

LINDERA is objective motion analysis for outpatient therapy. One smartphone capture measures gait and mobility in minutes, puts a measured number behind every evaluation and the medical necessity you have to defend, and hands your PTs and OTs a faster, defensible assessment. The clinician reviews and attests — the objective data does the heavy lifting.

LINDERA is an objective motion-analysis platform

A smartphone gait and mobility analysis that gives outpatient therapy teams measured, defensible evidence for every evaluation and the medical necessity behind each visit.

The number behind the necessity.

Every outpatient visit past the threshold has to be justified. When the case rests on a narrative impression, it's fragile — and that's where the denials and ADRs land. LINDERA puts an objective number underneath it: measured gait speed, balance, sit-to-stand, and SPPB, benchmarked to age-matched norms, captured the same way every time. The medical-necessity documentation is backed by evidence a reviewer can't wave away.

The clinician makes the determination and attests. LINDERA supplies the measured basis — KX- and threshold-aware — it does not assert necessity for you.

The bottleneck in outpatient therapy isn't care. It's the charting.

Only your PTs and OTs can perform and bill an evaluation — which makes their time the capacity ceiling of the clinic. Today that time leaks into documentation: a ten-to-fifteen-minute manual gait observation, a note written from memory after the visit, standardized tests recorded as a single number with nothing objective underneath. The result is fewer evaluations per clinician per week and documentation that drifts between assessments. LINDERA closes that gap — one capture, one measured record, one defensible draft the clinician verifies.

One capture. Three steps. Under five minutes.

  1. The therapist records a short guided movement sequence on a standard phone or tablet — a walk plus a sit-to-stand, Tinetti and a Timed Up and Go, with the clinician's observations captured in the same session. No markers, no wearables, no mats.
  2. LINDERA's AI measures the objective movement parameters from the video — gait speed, cadence, step length and symmetry, stride variability — against age-matched norms.
  3. The measured values are assembled into a suggested evaluation, reassessment, or discharge note at parity with your templates, with the objective numbers already in place. The clinician reviews, edits, and attests. Suggested only — the clinician verifies; the EHR submits.

LINDERA provides the objective layer; the clinician keeps the clinical judgment.

Measured, not just written.

The named, evidence-based tests reviewers expect — Timed Up and Go, sit-to-stand, the Short Physical Performance Battery, and full gait analysis — are captured in the same session and written into the eval as objective evidence, not narrative impression. The measurement is in the chart, tied to the field a reviewer reads. That's what makes a note defensible, not just complete.

The same measurement your patients can actually see.

The objective data that drafts the note also becomes a clear, visual report the patient understands. The patient — and their family — sees their own gait speed, balance, and strength against age-matched norms, and watches those numbers move across the plan of care.

Progress a patient can see is progress a patient believes. Objective, visual feedback drives buy-in, motivation, and adherence in a way "you're doing better" never will — and gives the patient something concrete to take home. For an outpatient clinic, that means stronger engagement, fewer no-shows, and better-finished plans of care.

The conversation the numbers make easier.

A measured report changes the conversation with the patient's family. Instead of "they're doing better," the clinician shows exactly where the patient stands — gait speed, balance, and strength against age-matched norms — and where they're headed. That objectivity is often what justifies the therapy and the care level the patient needs: families understand numbers they can see, and they support decisions backed by evidence rather than impression.

The care the patient actually needs — backed by evidence.

When the objective delta shows continued need, the measurement stands behind the full, appropriate course of care — so the right therapy isn't cut short by weak documentation, and the care level matches what the data justifies. The evidence protects the care the patient has genuinely earned.

The outcomes that bring the next patient.

Objective, visual outcomes are what set a clinic apart — to the physicians and discharge planners who decide where to send patients, and to the families who pass on a recommendation. Measured progress you can show is the most credible referral you have.

Where the hours and the capacity actually move.

  • Therapist throughput. A short objective capture and a drafted note replace a ten-to-fifteen-minute manual observation plus after-visit charting — more evaluations per PT/OT per week.
  • Documentation minutes saved per eval. Measured and reported, not asserted.
  • QA velocity. Completeness checks move each chart from red to green and show exactly what's missing — before it reaches billing.
  • Consistency between assessments. One objective source means the reassessment shows a measured change against baseline, not a re-typed narrative.
  • Patient & family buy-in. A visual report that explains the therapy and the care level in terms families understand and support.
  • More patients. Objective outcomes that stand out to referral sources — and win the next patient.

Most outpatient partners see net-positive economics inside the first quarter.

The evidence engine under the codes your therapists already bill.

LINDERA is not a billing tool. It is the objective measurement layer that makes outpatient therapy documentation defensible. Its output maps by descriptor to the work your clinicians do:

  • PT and OT evaluation — low, moderate, and high complexity.
  • PT and OT re-evaluation — a quantified change against baseline gait parameters.
  • Therapeutic exercise, neuromuscular reeducation, gait training, therapeutic activities — the impairments these target, captured objectively.
  • Physical performance test and assistive-technology assessment — the standardized, repeatable measurement set that distinguishes these from a routine visit.

The objective data — without the hardware, the integration project, or the retraining.

Wearable sensors need distribution, charging, and compliance. Force-plate and mat systems are capital equipment locked to one room. Manual standardized tests produce a single score with no objective data underneath. LINDERA is a smartphone app any therapist runs on the patient in the patient's own room — objective measurement, a drafted note, and a patient-facing report, all flowing into the EHR. No hardware to procure, no IT integration as a precondition, no retraining beyond a single onboarding session.

FAQ

What is LINDERA?

LINDERA is objective motion analysis for therapy. One smartphone capture measures gait and mobility and turns it into defensible, QA- and billing-ready documentation. The clinician reviews and attests.

How does LINDERA reduce documentation time for outpatient therapy?

It captures the eval once and returns a suggested eval, reassessment, or discharge note at template parity, with objective measurements already in place. The clinician reviews and attests instead of writing from scratch.

Does LINDERA replace standardized tests like TUG, Tinetti, or Berg?

Yes. The LINDERA US app includes the standardized functional tests your team already uses — Timed Up and Go, Tinetti, and Berg — captured objectively from a single smartphone video, alongside gait parameters a stopwatch and a score sheet can’t produce. You run the tests you trust, now with objective, defensible data underneath them. Independent comparison to TUG, Tinetti, and Berg is published in JMIR Aging (2022).

Does the patient see their results?

Yes. LINDERA produces a clear, visual report of the patient's measured gait, balance, and strength against age-matched norms, tracked across the plan of care.

Can LINDERA support remote therapeutic monitoring?

LINDERA captures device-collected, time-stamped, clinically reviewed measures of musculoskeletal function between visits. RTM billing features switch on after FDA clearance; today the value is the measured-function data stream.

Is LINDERA HIPAA-ready?

Yes — US-region hosting, Business Associate Agreements, and the audit-trail discipline US payers and surveyors expect. ISO 27001 certified.

How long does a pilot take?

About 60 days: onboarding and baseline, 45 days of operational use with weekly throughput and documentation-time tracking, then a review against the provider's own data. The deliverable is a quantified ROI report.

Can administrators see clinic-level trends?

Yes — throughput by clinician and setting, documentation-time saved, QA red-to-green velocity, and assessment volume.

What do I need to run it?

An iOS or Android phone or tablet, a stable internet connection, and storage for the app.
