Six risk factors. One configurable engine.
Every ergonomic hazard falls into six families. Each is assessed by validated methods — scored by AI from a phone capture, or camera-free from a structured survey, and signed off by a certified ergonomist. This is the full library; methods light up as each is productised.
Postures
How the body is held while working — sitting, standing, bending, twisting, reaching.
Driven by: Poorly set-up workstations, sustained static positions, and tasks that force awkward joint angles.
Leads to: Neck, shoulder, back and wrist musculoskeletal disorders (MSDs) — the leading driver of desk-work discomfort and presenteeism.
What we measure
- Anatomical-neutral deviation: Exact joint angles measured against clinical thresholds to flag high-risk positioning.
- Static-position tracking: Duration of uncorrected fixed postures that restrict blood flow and stiffen muscle.
- Multi-axial spinal twisting: Simultaneous bending and twisting that compromises spinal-disc integrity.
Scores neck, trunk, arm and wrist posture for upper-limb strain at the desk or bench.
Rates the whole office workstation as a system — chair, monitor, keyboard, mouse, phone.
Whole-body posture score for varied, unpredictable tasks like patient handling and assembly.
Classifies back, arm and leg postures across a full shift to map industrial posture load.
Whole-body assembly screen combining posture, force and manual handling into one score.
Estimates cumulative load on the upper body from sustained joint angles.
ISO limits for how long a static posture can be safely held.
Loads
Manual handling of weight — lifting, lowering, carrying.
Driven by: Heavy or awkwardly-placed loads, high lifting frequency, and poor lifting geometry.
Leads to: Lumbar (lower-back) injury — the single costliest manual-handling claim.
What we measure
- Weight-threshold mapping: Object weight benchmarked against safe guidelines to prevent overexertion.
- Asymmetrical-distribution analysis: Load handled away from the core, increasing spinal shear stress.
- Vertical & horizontal travel: Distance a load is lifted or carried, driving fatigue on major joints.
The gold-standard lifting check — computes a safe weight limit and lifting index for a task.
Population limits for pushing, pulling and carrying loads.
ISO limits for lifting, carrying, pushing, pulling and repetitive handling.
Forces
Effort exerted — gripping, pushing, pulling, sustained tension.
Driven by: High grip force, heavy tools, and forceful exertions during tool and equipment use.
Leads to: Tendon and soft-tissue disorders in the hand, wrist and forearm.
What we measure
- Grip & pinch-pressure tracking: Localised force in the hands and fingers during tool or material handling.
- Push-pull resistance modelling: Forces required to start or sustain movement of carts, machinery, or assets.
- Sustained-muscle-tension logs: Periods of continuous isometric contraction that accelerate fatigue.
Scores hand/wrist-intensive tasks on intensity, posture, speed and duration of exertion.
REBA's force/coupling adjustment captures grip and load during whole-body tasks.
Estimates joint forces and torque for high-load tasks.
Repetition
How often the same movement is repeated — cycle times and task frequency.
Driven by: Short-cycle repetitive work — assembly, typing, scanning, packing — with too little recovery.
Leads to: Cumulative-trauma disorders such as tendinitis and carpal tunnel syndrome.
What we measure
- Cycle-time frequency: Duration of repeated sequences, flagging ultra-short, high-frequency actions.
- Tissue-recovery allocation: Ratio of active exertion to structured rest within each movement cycle.
- Cumulative daily motions: Total repetitive movements aggregated across the full shift.
Environment
The physical conditions around the work — lighting, noise, temperature, vibration, air.
Driven by: Poor lighting and glare, excess noise, thermal discomfort, and tool/vehicle vibration.
Leads to: Eye strain, fatigue, hearing risk, and hand-arm or whole-body vibration disorders.
What we measure
- Thermal-stress audits: Heat or cold levels and their effect on muscular flexibility and dexterity.
- Vibration-exposure logs: Hand-arm or whole-body vibration from tools and machinery.
- Visual ergonomics & glare: Lighting, contrast, and reflections that trigger posture adjustments or eye strain.
Predicts thermal comfort/discomfort from temperature, humidity, airflow and clothing.
Measures whole-body vibration exposure from vehicles and platforms.
Measures hand-arm vibration from power tools.
Evaluates the work environment and organisation, including mental load.
A practical checklist across workstation, environment and tools.
Global & Psychosocial
Whole-job factors — workload, stress, autonomy, shift patterns, and reported discomfort.
Driven by: Excessive pace and overtime, low control, weak support, and unmanaged fatigue.
Leads to: Stress, burnout, and the early-warning discomfort that precedes a reportable MSD.
What we measure
- Cognitive-workload indexing: Mental fatigue and frustration during complex or high-pressure intervals.
- Shift-pattern sustainability: Impact of irregular hours and rapid rotations on natural recovery cycles.
- Discomfort-symptom mapping: Anonymous self-reported strain matched to objective floor risks.
Evaluates work pace, mental load and organisation alongside the environment.
Self-report of mental workload across six dimensions.
Surveys psychosocial risk — demands, influence, support, stress.
Measures job demand, control and support.
Maps where workers feel musculoskeletal discomfort — the standard discomfort survey.
