Workplace Ergonomics Course for Physical Therapists

Lesson 1 • Biomechanical Principles in Work Tasks

Core biomechanics—force, torque, and lever systems—are applied to common work movements. Students analyze how mechanical loads accumulate during repetitive tasks.

Lesson 2 • Human Anatomy for Ergonomic Practice

Musculoskeletal anatomy is reviewed through an occupational lens. Students connect anatomical structures to injury mechanisms seen in workplaces.

Lesson 3 • Defining Ergonomics and Its Scope

Ergonomics is defined as the science of fitting work to the worker. This section grounds students in terminology and the discipline's boundaries.

Lesson 4 • Physiology of Fatigue and Recovery

Muscle fatigue, metabolic demand, and recovery physiology are examined in occupational contexts. Students predict fatigue onset and design work-rest ratios accordingly.

Lesson 1 • Classification of WMSDs

WMSDs are categorized by tissue type, body region, and onset pattern. This taxonomy enables precise clinical reasoning throughout the course.

Lesson 2 • Risk Factors and Exposure Models

Physical, psychosocial, and organizational risk factors are examined using dose-response models. Students quantify exposure levels to prioritize intervention targets.

Lesson 3 • Pathophysiology of Common WMSDs

Tissue-level injury mechanisms for prevalent WMSDs are detailed. Students link pathophysiology to observable clinical signs and functional limitations.

Lesson 4 • Epidemiology and Industry Patterns

Prevalence data and industry-specific WMSD patterns are analyzed. Students use epidemiological evidence to anticipate high-risk occupational groups.

Lesson 1 • Measurement and Instrumentation

Objective measurement tools—goniometers, force gauges, and accelerometers—are introduced for precise exposure quantification. Students calibrate and apply instruments in simulated work settings.

Lesson 2 • Workstation Measurement and Documentation

Physical workstation dimensions are measured and recorded to support redesign recommendations. Students produce standardized assessment reports suitable for employer review.

Lesson 3 • Observational Assessment Tools

Structured observational methods are used to rate posture and task risk without instrumentation. Students practice scoring reliability and interpreting action levels.

Lesson 4 • Task Analysis Techniques

Systematic task decomposition reveals hidden exposure sources within complex jobs. Students break down multi-step tasks to isolate high-risk elements.

Lesson 1 • Seated Posture and Spinal Loading

Lumbar and cervical loading during prolonged sitting is analyzed biomechanically. Students identify postural deviations that increase disc pressure and muscle fatigue.

Lesson 2 • Visual Ergonomics and Lighting

Visual demands of screen-based work and their relationship to eye strain and neck posture are examined. Students assess lighting conditions and recommend corrective measures.

Lesson 3 • Upper Limb Disorders in Office Work

Repetitive keyboard and mouse use is linked to specific upper limb WMSDs. Students assess input device usage patterns and recommend targeted modifications.

Lesson 4 • Workstation Setup and Adjustment

Chair, desk, monitor, and keyboard parameters are set using anthropometric guidelines. Students perform full workstation setups for workers of varying body dimensions.

Lesson 1 • Hand-Arm Vibration and Tool Use

Power tool vibration and grip force demands are evaluated for their contribution to vascular and neurological disorders. Students select tools and gloves to minimize hand-arm vibration syndrome risk.

Lesson 2 • Pushing, Pulling, and Carrying

Force requirements for wheeled and non-wheeled transport tasks are measured and compared against population capacity data. Students specify handle heights and floor surface requirements.

Lesson 3 • Whole-Body Vibration Exposure

Vibration transmission through vehicle seats and standing platforms is assessed against health-based exposure limits. Students recommend engineering and administrative controls for vibration reduction.

Lesson 4 • Overhead and Awkward Posture Tasks

Shoulder and neck loading during overhead work is quantified and linked to rotator cuff injury risk. Students redesign work heights and tool access to eliminate sustained overhead postures.

Lesson 1 • Assistive Technology and Automation

Mechanical assists, exoskeletons, and automation options are evaluated for their ergonomic and operational impact. Students match technology solutions to specific task demands and workplace constraints.

Lesson 2 • Job Rotation and Task Restructuring

Job rotation schedules and task restructuring reduce cumulative exposure across body regions. Students design rotation plans that balance workload without transferring risk.

Lesson 3 • Intervention Implementation Planning

Phased implementation plans are developed with stakeholder engagement and measurable success criteria. Students write intervention briefs that communicate risk reduction rationale to non-clinical audiences.

Lesson 4 • Hierarchy of Ergonomic Controls

Elimination, substitution, engineering, administrative, and personal protective controls are ranked by effectiveness. Students apply the hierarchy to select the most impactful intervention for each risk.

Lesson 1 • New and Inexperienced Workers

Inexperienced workers face elevated WMSD risk due to unfamiliar tasks and underdeveloped movement patterns. Students design onboarding ergonomic programs that build safe work habits from day one.

Lesson 2 • Aging Workers and Physical Capacity

Age-related changes in strength, flexibility, and sensory function are quantified and applied to workstation design. Students modify task demands to match the reduced but variable capacity of older workers.

Lesson 3 • Pregnancy and Ergonomic Risk

Physiological changes during pregnancy alter postural stability, load tolerance, and fatigue thresholds. Students identify trimester-specific risk factors and recommend safe work modifications.

Lesson 4 • Gender and Anthropometric Variability

Anthropometric differences across gender and body size are used to adjust workstation and tool parameters. Students select percentile-based design targets that accommodate diverse worker populations.

Lesson 1 • Hazard Identification and Prioritization

Systematic hazard identification processes are integrated into routine workplace inspections. Students build risk registers that rank ergonomic hazards by severity and exposure frequency.

Lesson 2 • Injury Data Analysis and Surveillance

Injury records, near-miss reports, and symptom survey data are analyzed to identify program gaps. Students use trend analysis to evaluate program effectiveness and justify resource allocation.

Lesson 3 • Program Evaluation and Continuous Improvement

Evaluation frameworks measure ergonomic program impact on injury rates, productivity, and worker satisfaction. Students apply continuous improvement cycles to refine program components based on outcome data.

Lesson 4 • Program Design and Governance

Ergonomics program structure, roles, and governance frameworks are established to ensure accountability. Students draft program charters that align ergonomic goals with organizational health and safety strategy.
