Biomechanical AI for Occupational Health

Preventing the Sykefravær Crisis Through Biomechanical Intelligence

SALA is a proactive AI platform designed to tackle the high rate of absences due to musculoskeletal disorders in the transport sector. Unlike reactive HMS systems, SALA intervenes before injury occurs — monitoring biomechanical risks in real time.

The Biomechanical Algorithm

SALA calculates the Risk Index (Ri) focused on the human element — not just the vehicle. Our proprietary algorithm integrates four critical biomechanical factors.

Lumbar L5/S1 Analysis

Real-time monitoring of vertebral compression during load lifting. The L5/S1 joint bears the highest biomechanical stress, making it the critical point for injury prevention.

Ccompress = Fload × dmoment × kposture

Surface Factor (Sf)

Dynamic adjustment for critical conditions — Norway's harsh winters with ice and snow can increase spinal stabilization effort up to 3×. The algorithm adapts risk thresholds in real time.

Sf = μice × θslope × Wseasonal

Vibration Exposure (ISO 2631-1)

Protection against whole-body vibration (WBV) to prevent neuromuscular fatigue and chronic pain. Continuous monitoring aligned with international safety standards.

WBVdaily = A(8) × √texposure

Accumulated Fatigue

Modeling based on the Norwegian work standard (37.5h/week) and environmental stressors. Tracks cumulative load across shifts to prevent chronic overexposure.

Ftotal = Σ(Fshift × Rrecovery)

Risk Index Ri Dashboard

The Risk Index synthesizes all biomechanical factors into a single actionable metric, enabling immediate intervention before injury occurs.

Ri Score
Current Biomechanical Risk Level

Low Risk (0–30)

Normal operations — continue standard procedures

Moderate Risk (31–65)

Recommend mechanical assistance or load division

Critical Risk (66–100)

Immediate intervention required — halt operation

Transforming Safety Management

SALA shifts occupational safety from reactive compliance to proactive prevention, protecting workers while optimizing operations.

Real-Time Alerts

Drivers receive immediate strategic recommendations via the app — such as requesting mechanical assistance or dividing loads — when risk reaches critical levels.

AML § 4-4 Compliance

The system automates compliance with Norway's Working Environment Act (Arbeidsmiljøloven), providing actionable data for safety delegates (Verneombud).

Economic ROI

Massive cost reduction through decreased sick leave (sykemelding), lower staff turnover, reduced insurance premiums, and indirect costs for companies and NAV.

Built for Norwegian Compliance

Fully aligned with Norwegian occupational health legislation and international biomechanical standards.

Arbeidsmiljøloven § 4-4

  • Automated documentation of biomechanical risk assessments
  • Real-time data feeds for safety delegates (Verneombud)
  • Shift-level exposure tracking aligned with 37.5h standard
  • Audit-ready reports for regulatory inspections
  • Proactive intervention logs demonstrating duty of care

International Standards

  • ISO 2631-1: Whole-body vibration assessment
