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 The rehabilitation team configures a myoelectric hand for one empty-foam-cup transfer, with rest windows, fit checks and a safe open or powered-down default. The learner controls the declared grasp, counts unintended activations and handles one signal fault. Heavier, sharp and everyday objects remain outside the demonstrated capability. Target outcome: With the rehabilitation team, the learner calibrates rest and active states, completes a provider-selected grasp, counts unintended activations and returns to a safe open or powered-down state. ### Authority and setup conditions - Obtain rehabilitation-team clearance and the device-specific training plan. - Use only the configured device, empty foam object, clear table and approved stop procedure. - Start check for Prosthetic control: Target, load, distance and stop state are exact. - Top-of-sheet stop for Prosthetic control: Stop for skin redness that persists, wound, swelling, pain, heat, odour, loose hardware or new discomfort. ### Required or supplied materials - Declared Prosthetic control fixture: A myoelectric training hand moves an empty foam cup from one marked pad to another on a table. The prosthetist controls fit, thresholds and permissible repetitions. - Setup aid for Inspect fit and skin: Use only the configured device, empty foam object, clear table and approved stop procedure. - Prosthetic control log: Task success, control error, comfort, wear time, abandonment, maintenance and device-on/off daily participation; retain Prosthetic control errors, assistance, stop and fallback. - Prosthetic-control provider sheet: from “Self-Contained Neuromusculoskeletal Arm Prostheses”, record interface, trained actions, device configuration and functional outcome; from the myoelectric robot-assisted training pilot, record participants, training condition, dose owner and measured change. Use the WHO/UNICEF report to keep the user goal, fallback and service support visible. Only the prosthetist sets fit and thresholds. ## 1. Choose one functional action The learner and team define “grasp the empty foam cup, move 20 cm and release on the blue pad,” plus the safe default. Why: Target, load, distance and stop state are exact. Success check: Target, load, distance and stop state are exact. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Target, load, distance and stop state are exact.” 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. Inspect fit and skin The prosthetist checks socket, electrodes, alignment, skin, comfort and device condition before activation. Why: No new redness, wound, pressure or loose component is present. Success check: No new redness, wound, pressure or loose component is present. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No new redness, wound, pressure or loose component is present.” 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. Record the rest signal With the limb supported, relax for the provider-set interval while the clinician checks baseline noise and unintended movement. Why: The device remains in the safe default during rest trials. Success check: The device remains in the safe default during rest trials. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The device remains in the safe default during rest trials.” 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. Calibrate one active command Produce the agreed muscle signal while the provider sets and verifies the threshold; do not change settings independently. Why: The intended open or close command occurs without a second function firing. Success check: The intended open or close command occurs without a second function firing. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The intended open or close command occurs without a second function firing.” 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 an object Practise open, approach, close, hold and open at slow speed, returning to default between trials. Why: The sequence completes three times without unintended activation. Success check: The sequence completes three times without unintended activation. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The sequence completes three times without unintended activation.” 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. Move the foam cup Approach inside the marked zone, grasp with provider-approved force, move to the blue pad and fully release. Why: Cup arrives upright and the hand returns to default. Success check: Cup arrives upright and the hand returns to default. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Cup arrives upright and the hand returns to default.” 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. Log error and comfort Record success, drop, crush, unintended activation, correction, comfort and assistance for every trial. Why: No error is hidden inside an overall success count. Success check: No error is hidden inside an overall success count. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No error is hidden inside an overall success count.” 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. Test fallback and finish On a staged signal fault, stop, support the device and use the team’s disable or removal procedure; inspect skin again. Why: The learner demonstrates the stop response and the provider authorises the next step. Success check: The learner demonstrates the stop response and the provider authorises the next step. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner demonstrates the stop response and the provider authorises the next step.” 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.
