Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context A trained team evaluates a back-support device through an unloaded rehearsal and one empty-crate move between waist-high benches. The learner respects the exclusion zone, turns with the feet, identifies an assistance-timing mismatch and demonstrates stop and safe removal. This cannot establish greater strength, injury prevention or workplace readiness. Target outcome: Under trained supervision, the learner completes an unloaded rehearsal and one approved light task, logs human–device error and demonstrates the stop and safe-removal procedure. ### Authority and setup conditions - Obtain device-specific training, task assessment and same-day clearance from the responsible team. - Prepare the empty crate, level route, exclusion zone, spotter and tested emergency release. - Start check for Robotic strength augmentation: No task parameter is left for the learner to increase. - Top-of-sheet stop for Robotic strength augmentation: Stop for pain, dizziness, loss of balance, skin pressure, numbness, breathlessness, heat stress or unusual fatigue. ### Required or supplied materials - Declared Robotic strength augmentation fixture: A back-support exoskeleton is evaluated in a controlled work simulation: move an empty crate from one waist-high bench to another one metre away. No floor lift or added load is permitted. - Setup aid for Screen person and environment: Prepare the empty crate, level route, exclusion zone, spotter and tested emergency release. - Robotic strength augmentation log: Supported task output, whole-body loading, discomfort, heat, balance, errors, discontinuation and device-off strength; retain Robotic strength augmentation errors, assistance, stop and fallback. - Strength-augmentation evidence sheet: from “Effects of 24-weeks in-field use of a back-supporting exoskeleton on biomechanics, work intensity and musculoskeletal discomfort”, record workplace tasks, device exposure, comparator, biomechanical and discomfort outcomes, and adverse events. Do not convert the study into a load prescription. Use the NIST Privacy Framework to limit collection of worker movement and discomfort data during the empty-crate simulation. ## 1. Define the narrow task The responsible ergonomics or clinical team states the empty crate, bench heights, one-metre route, device model/mode and prohibited movements. Why: No task parameter is left for the learner to increase. Success check: No task parameter is left for the learner to increase. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No task parameter is left for the learner to increase.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Screen person and environment The provider checks health, fit criteria, clothing, floor, overhead clearance, exclusion zone and rescue/removal plan. Why: The learner and spotter know the stop path. Success check: The learner and spotter know the stop path. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner and spotter know the stop path.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Inspect and fit the device Trained staff check fasteners, alignment, battery, heat, limits, emergency release and skin/contact areas. Why: Fit is approved before activation. Success check: Fit is approved before activation; verify it in the back-support crate transfer. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Fit is approved before activation; verify it in the back-support crate transfer.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Record device-off baseline Move the empty crate once without the powered/support mode, using the team’s ordinary handling plan; record time, discomfort, balance and movement. Why: Comparator uses the same crate and route. Success check: Comparator uses the same crate and route. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Comparator uses the same crate and route.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Rehearse without the crate Practise stand, turn with feet, approach, pause and emergency stop while the device is unloaded. Why: Learner can stop and remain balanced inside the zone. Success check: Learner can stop and remain balanced inside the zone. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Learner can stop and remain balanced inside the zone.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Perform one assisted transfer At the provider-set mode, take the empty crate, walk one metre, place it fully and release before repositioning. Why: No collision, jerk, limit warning or trapped hand occurs. Success check: No collision, jerk, limit warning or trapped hand occurs. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No collision, jerk, limit warning or trapped hand occurs.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Respond to mismatch If the device pushes at the wrong time, stop, set down, use the emergency cue and let staff disable/remove it. Why: The learner does not fight the device or continue carrying. Success check: The learner does not fight the device or continue carrying. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner does not fight the device or continue carrying.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Compare total outcome Record task time, assistance, discomfort, heat, balance, errors, discontinuation and device-off ability; provider and learner decide next use. Why: Reduced local muscle effort is not called injury prevention or human strength gain. Success check: Reduced local muscle effort is not called injury prevention or human strength gain. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Reduced local muscle effort is not called injury prevention or human strength gain.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
