Actuarial infrastructure for
musculoskeletal injury risk.
Powered by autonomous, force-controlled stretching. Built for longitudinal risk intelligence.
The Problem
Strength has force plates. Speed has timing gates. Recovery has Normatec. But flexibility and joint mobility — the biggest levers for injury prevention — are still estimated by eye and documented on paper.
The full scope — every muscle group Modulor addresses:
• Muscle strains are the largest single injury category in elite football: hamstrings 42%, adductors 25%, quadriceps 19%, calves 14%. Re-injury rates: adductors 29%, hamstrings 30%. (Eirale et al., epidemiological review, Br J Sports Med)
• 25% of NFL players suffer a lower-extremity strain every season — 33% re-injury rate. (Jenkins et al., 12-year review of 2,101 NFL hamstring injuries, Orthop J Sports Med 2024)
• 21% of professional footballers suffer a groin/adductor injury every season; 68% are adductor-related. (Werner et al., 17-club 606-player UEFA prospective study, Br J Sports Med)
• Restricted hip internal rotation and ankle dorsiflexion are independent risk factors for ACL injury — 83% of studies in a 2,819-athlete systematic review confirmed the link. (Belkhelladi, Cierson & Martineau, Orthop J Sports Med 2025)
• Hamstring injuries have DOUBLED from 12% to 24% of all injuries in men's professional football over 21 years — training injuries rising 6.7% annually despite modern training science. (Ekstrand et al., UEFA Elite Club Injury Study, Br J Sports Med 2023)
• Economic impact: top LaLiga clubs lose €7M+ annually to muscle injuries; Premier League teams spent £266M total on sidelined players' wages in 2023/24 — £83M on hamstrings alone. (Melcón-Ballesteros et al., PLOS One 2024; Premier Injuries Ltd. 2024)

The Solution
The athlete straps in. A motorized cable stretches them at calibrated force. Onboard sensors feel exactly where tissue yields. A depth camera catches the compensations that mask true range. Every session, a structured record of what was actually found.

The Product
FIG. 2 — Apparatus Side-View Schematic
10 BLDC motor 12 Planetary gearbox 14 Cable spool 16 Inline load cell 18 Quick-release cuff 20 Depth camera 22 Touchscreen 24 E-stop 26 Frame + bench
The athlete straps in, attaches a quick-release cuff, and the machine does the rest — no clinician, no partner required.
Compliance by design. Athletes do ~0% of unsupervised home mobility work and ~100% of what a clinician walks them through. The machine is the present clinician — guided, timed, force-controlled, recorded. Every rep counted means every session compounds the corpus.

What It Measures
Manual goniometry measures a pose — one plane, one moment, examiner-graded. Modulor measures the movement — continuous, multi-joint, both sides, at 100 Hz.
FIG. 8 — Measurement Extraction Pipeline (Raw Sensor → Derived Variables)
Apparatus claim: Three independent sensor inputs (40, 42, encoder) are fused at element 60 to derive nine biomechanical variables (V1–V9), fed to longitudinal risk scoring engine (62).
Peak passive ROM at standardized force. ±2° accuracy. Comparable across sessions.
Inline load cell at 100Hz. Logs tension ramp, peak force, and variability during hold.
Left vs. right at matched force. Flags differences >10%. Tracks resolution over time.
Duration at end-range without retreating. A neuromuscular tolerance metric.
Camera detects pelvic rotation, knee bend, trunk shift. Quantified, not eyeballed.
The force level where the athlete first reports discomfort or resists. Tracked over weeks.
Binary flag per rep. Correlated with force and ROM to build a tissue-response profile.
Rate of force acceptance during initial stretch. Indicates tissue readiness and stiffness.
Acute ROM gain per session. Chronic trend over weeks. The metric that matters most.

Competitive Landscape
The real competitive set is the full injury-risk measurement ecosystem — force plates (VALD ForceDecks, Hawkin), motion capture (VALD HumanTrak, Theia, Sparta), and stretch-focused hardware (StretchLab, Normatec, Hyperice). Each owns a slice. Modulor integrates motorized, force-controlled stretching with real-time biomechanical measurement and longitudinal data — the only intervention surface that also generates the measurement corpus.
AMS layer (Smartabase, Catapult) is integration, not competition — Modulor data plugs in.
Jump / squat force output. Adjacent budget. No ROM, no stretch, no intervention surface.
Kinematics from markerless video. Measurement-only; no calibrated load, no intervention layer.
Clinical isokinetic. $100K+. Not designed for stretching protocols. No vision tracking.
Manual 1:1 service. $60/session. No measurement, no data, no consistency.
Compression + percussion recovery. No active stretch. No ROM measurement.
Subjective assessment. No force control, no objective measurement. Rarely documented longitudinally.

Market Opportunity
Stretching is the wedge. The product is a measurement + risk-pricing layer. Five independent buyers monetize the same underlying corpus — seed-stage commercial wedge is pro + collegiate Teams; DoD is the non-dilutive capital channel, not the first-pilot source; Insurance, Leagues, and Strategic unlock as the data corpus compounds.
Buyer 1 · Hardware lease
~800 addressable programs in NA + EU. Target $60K/yr/station. Every franchise has a training-room budget and an injury-prevention mandate.
Buyer 2 · Data licensing · long-term
$70B+ US market. MSK is ~40% of claims. Long-term roadmap — unlocks after peer-reviewed clinical validation + 10K+ athlete-months in corpus. Target at maturity: $250K–$1M per carrier / yr. Not a seed-stage revenue claim.
Buyer 3 · Non-dilutive + hardware
~800K MSK injuries/yr active-duty — 100× pro sport. SOFWERX, AFWERX, DIU are funded pilot rails. Same hardware; subscription fits training-hub budgets. Doc 19 →
Buyer 4 · Enterprise
Roster-level availability models. Standardized injury reporting aligned to CBAs. Long sales cycle — large check.
Buyer 5 · Strategic exit
Patent + data corpus are the asset. Acquisition-optimized. Adjacent distribution already owns the consumer surface.
Lease-only model. Every install compounds the data corpus. Physical switching cost protects the moat once deployed.

Defensibility
A competitor can build a cable machine. They cannot replicate three years of elite athlete flexibility data, a peer-reviewed MSK injury risk study, and a workflow embedded in every major AMS.
ROM norms for NFL linemen, Army Rangers, Division I athletes — by position, by load, by season. Once collected, no competitor can replicate it without 3–5 years of their own installs. This is the asset that gets licensed to insurers and leagues — not the hardware.
A published study — hazard-ratio curves linking ROM / asymmetry deltas to downstream MSK injury risk — becomes the permanent evidence standard. We don't pre-claim the predictive window; the dataset tells us where it lands. Competitors must produce their own equivalent study. That's 2–3 years of lag minimum — and we set the reference the whole field cites.
Once a team's physician is using Modulor ROM delta as a return-to-play criterion and the data is flowing into Smartabase or Catapult, switching means losing the athlete's entire longitudinal record. The data-rights clause in every lease — de-identified corpus retained in perpetuity — is the contractual foundation of this layer.
The device itself is positioned as Class I, 510(k)-exempt (performance / wellness; product codes ISD / KQX / NKI). Pursuing clearance for the injury-risk scoring output as a medical device puts any competitor entering the clinical space 12–24 months behind us in queue. Not a wall — a head start that compounds with the data advantage.
The one clause that makes this work: Every pilot and lease contract includes a data-rights provision — the team gets their athlete data back into their AMS; Modulor retains the de-identified corpus in perpetuity. Embedded from day one, this clause is what turns hardware revenue into a data company.

USPTO Provisional Application 64/040,028 · filed April 15, 2026 · 35 U.S.C. § 111(b)
FIG. 1 — System Block Diagram (Force-Controlled Stretch with Compensation-Aware Adjustment)
System claim: Elements 200–214 define the complete closed-loop system. The red dashed path (210 → 204) represents the novel compensation-aware force adjustment — vision-detected compensation modifies the PID setpoint in real time.
FIG. 10 — PID Force-Compliance Control Loop (Element 204 Detail)
Method claim: The PID controller (204) maintains force setpoint while the compensation signal from the vision system (210) dynamically modifies the target, creating a dual-feedback architecture unique to this apparatus.
FIG. 11 — Compensation Detection & Adaptive Force Response (Element 210 Detail)
Method claim: The compensation classifier (224) analyzes pose data to detect pelvic rotation, knee bend, or trunk shift, then proportionally reduces force setpoint — the core novel mechanism that distinguishes Modulor from all existing stretch devices.
A method for force-controlled stretching with compensation-aware adjustment, comprising: applying motorized cable tension via PID force control (204), detecting movement compensation via depth-camera pose estimation (210, 224), and dynamically modifying the force setpoint in response to detected compensation.
An integrated cable-drive and vision feedback stretching apparatus comprising: a motorized spool (34) with inline force sensing (42), a depth camera (40) with skeletal tracking (220), a PID compliance controller (204), and a compensation classifier (224) that adjusts cable tension in real time.
A bilateral assessment and adaptive protocol system comprising: standardized force application (F_set), bilateral ROM comparison (Δ = |θ_L − θ_R|), longitudinal trend analysis with injury risk scoring (62), and adaptive protocol modification (214) based on historical session data.
Figures 1–11 document the complete system. Prior art gap is strong — no existing device combines motorized cable stretching with real-time vision-based compensation detection and adaptive force modification.

Integration Layer
We do not build our own AMS, programming app, or wearable. Every existing platform is a pipe we feed. That's how the hardware becomes infrastructure, not a sensor.
Tier 1 · V1 must-haves
Pilot gate: "we use X" cannot be a reason we lose the deal.
Tier 2 · 6-month unlock
Each unlocks a specific buyer category.
Carriers don't integrate with point tools. They license aggregated, anonymized risk signals via data-licensing APIs. Target: $250K–$1M / carrier / yr after Year 2. No claims-system integration needed — just signed BAAs and a data feed.
Never write bespoke code for one customer. Every integration is a reusable template. Every custom request gets redirected to the public REST API + webhook pattern. Cheap per customer, compounding over time.
Data-rights clause in every lease contract. Teams get their data back into their AMS; we retain the de-identified corpus in perpetuity. This is the insurance-licensing precondition. Full plan: Doc 20.
