## Canonical source context

This is a static, no-movement worksheet. It teaches the difference between arriving at a declared angle and controlling an already-recorded task there. All angles, cursor samples and support configurations are fictional. Do not copy a position, test a joint, hold an end range, remove support, add load or use pain as data. This supplement deliberately uses the governed lesson’s no-attempt record route; it neither replaces nor expands the separately declared bounded configuration. The worksheet score checks calculations and boundary reasoning; it does not score a body. Angle-specific improvement can be described only inside the same device and support configuration. It cannot establish tissue integrity, joint safety, whole-range control or injury prevention.

Target outcome: Define end-range control without inheriting mythology or broader claims. Explain what the current evidence supports and what it does not establish. Use the declared measurement boundary and recognise misleading proxies. Complete only the separately governed capability practice inside its declared limits. Make a retention, transfer, maintenance, provider or stop decision without overclaiming.

### Authority and setup conditions

- Use only the bounded configuration. Use words, a diagram, or a movement already approved and comfortable. Do not add a hold, resistance, load or new end-range attempt.
- Stop if the frame is being turned into an end-range hold, loaded position, pain test or joint challenge.
- Stop if the reader feels pressure to remove support or exceed a comfortable, clinician-approved boundary.

### Required or supplied materials

- The four fictional device records in the fixture table; no person, joint movement, goniometer or physical demonstration is required.
- Formula card: arrival error = absolute value of observed angle minus target angle; mean absolute error from target = sum of the absolute cursor deviations divided by five; an in-band sample is any cursor deviation from -1 degree through +1 degree, inclusive.
- Calculation sheet with four labelled rows E1–E4 and columns for arrival error, five absolute deviations, deviation sum, mean absolute error from target, in-band count, valid comparison and bounded conclusion.
- Boundary card: STATIC RECORDS ONLY; supports stay in the configuration; no target angle, stretch, hold, repetition, duration, load, progression, pain test or safety claim.
- Calculator, optional, and the answer key kept hidden until all four rows are classified.

### Supplied fixture

Fictional angle-control device records; cursor deviations are already recorded and request no movement

| Case | Target angle | Observed arrival | Device and support | Five cursor deviations from target | Context note |
| --- | --- | --- | --- | --- | --- |
| E1 | 120 degrees | 118 degrees | Device Q7; forearm cradle C1 | -2, -1, +1, +2, +1 degrees | Baseline at the declared 120-degree configuration |
| E2 | 120 degrees | 120 degrees | Device Q7; forearm cradle C1 | 0, +1, 0, -1, 0 degrees | Later record in the same declared configuration |
| E3 | 90 degrees | 90 degrees | Device Q7; forearm cradle C1 | 0, +3, -2, +3, -2 degrees | Different angle; no whole-range inference is permitted |
| E4 | 120 degrees | 120 degrees | Device Q7; no forearm cradle | 0, +2, -3, +4, -2 degrees | Support changed; not like-for-like with E1 or E2 |

## 1. Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy…

Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy the in-band rule exactly: deviations from -1 degree through +1 degree count; -2 and +2 do not.

Why: “Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy the in-band rule exactly: deviations from -1 degree through +1 degree count” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.

Success check: A legible entry directly completes “Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy the in-band rule exactly: deviations from -1 degree through +1 degree count” and records the requested condition, decision or boundary without adding a new claim.

Accessible alternative: Complete the same research action — “Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy the in-band rule exactly: deviations from -1 degree through +1 degree count; -2 and +2 do not.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “Write STATIC/NO MOVEMENT at the top of the calculation sheet and copy the in-band rule exactly: deviations from -1 degree through +1 degree count” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice.

Alternative relationship: Target preserving when declared check is preserved

## 2. Copy each target angle, observed arrival angle, support code and five cursor…

Copy each target angle, observed arrival angle, support code and five cursor deviations without changing signs or dropping zeroes.

Why: “Copy each target angle, observed arrival angle, support code and five cursor deviations without changing signs or dropping zeroes” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.

Success check: A legible entry directly completes “Copy each target angle, observed arrival angle, support code and five cursor deviations without changing signs or dropping zeroes” and records the requested condition, decision or boundary without adding a new claim.

Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Use text-to-speech, enlarged text, keyboard navigation, shorter sessions, a support person or an equivalent non-practical record format as needed. Accessibility changes must not enlarge practical authority.

## 3. Calculate arrival error first, then convert every cursor sample to its absolute…

Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target.

Why: “Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.

Success check: The work shows the value requested by “Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target”, retains the supplied units or signs and leaves any unsupported value unknown.

Accessible alternative: Complete the same research action — “Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The work shows the value requested by “Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target”, retains the supplied units or signs and leaves any unsupported value unknown.” Do not convert the research task into capability practice.

## 4. Count in-band samples separately from the mean

Count in-band samples separately from the mean. Do not call a zero arrival error stable until the five-sample record is checked.

Why: “Count in-band samples separately from the mean” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.

Success check: A legible entry directly completes “Count in-band samples separately from the mean” and records the requested condition, decision or boundary without adding a new claim.

Accessible alternative: Complete the same research action — “Count in-band samples separately from the mean. Do not call a zero arrival error stable until the five-sample record is checked.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “Count in-band samples separately from the mean” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice.

## 5. Permit a direct performance comparison only when target angle, device and support…

Permit a direct performance comparison only when target angle, device and support code match. Otherwise describe each record separately.

Why: “Permit a direct performance comparison only when target angle, device and support code match” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.

Success check: A legible entry directly completes “Permit a direct performance comparison only when target angle, device and support code match” and records the requested condition, decision or boundary without adding a new claim.

Accessible alternative: Complete the same research action — “Permit a direct performance comparison only when target angle, device and support code match. Otherwise describe each record separately.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “Permit a direct performance comparison only when target angle, device and support code match” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice.

Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety.

Why: “Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety” carries the authored End-range control method into a reviewable output without adding an unstated task, dose or claim.

Success check: Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety.”

Accessible alternative: Complete the same research action — “Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety.”” Do not convert the research task into capability practice.
