Read angle-specific control from fictional device records without moving
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.

Read angle-specific control from fictional device records without moving
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.
Authority and safety
- 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.
Exact 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.
Set up in this order
- 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.
- Copy each target angle, observed arrival angle, support code and five cursor deviations without changing signs or dropping zeroes.
- Calculate arrival error first, then convert every cursor sample to its absolute value before calculating the mean absolute error from target.
- Count in-band samples separately from the mean. Do not call a zero arrival error stable until the five-sample record is checked.
- Permit a direct performance comparison only when target angle, device and support code match. Otherwise describe each record separately.
- Finish each row with one supported statement and one explicit non-claim about untested angles, supports or tissue safety.
Supplied fixture
| 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 |

Scoring rule
Score the worksheet, never the person. For each case award 1 point for correct arrival error, 1 for the correct mean absolute error from target, 1 for the correct in-band count and 1 for a configuration-bounded interpretation: 16 points total. Passing requires at least 14 points, the E1–E2 comparison identified as the only direct comparison, and E3/E4 not treated as transfer evidence. Any instruction to copy a position, stretch, hold, load, remove support, test pain or progress receives STOP rather than a score.
Worked example
- For E1, compute arrival error: |118 - 120| = 2 degrees.
- Remove signs from the five deviations: 2, 1, 1, 2 and 1 degrees.
- Add them: 2 + 1 + 1 + 2 + 1 = 7 degrees; divide by five to obtain 1.4 degrees mean absolute error from target.
- Apply the inclusive -1-to-+1 band: -1, +1 and +1 count, while -2 and +2 do not, giving three of five.
- Write the bounded result: E1 shows imperfect arrival and variable five-sample control at 120 degrees on Device Q7 with cradle C1.
Correct result: E1 earns 4/4 when reported as 2-degree arrival error, 1.4-degree mean absolute error from target, 3/5 in-band samples and a configuration-specific conclusion. It says nothing about another angle, unsupported control, tissue safety or a movement prescription.
Right and wrong
| Moment | Right / safer | Wrong / riskier | Why |
|---|---|---|---|
| Reading E3 | Report zero arrival error and 2.0-degree mean absolute error from target at the separate 90-degree record. | Call E3 stable because the observed arrival equals the target. | Arrival and sustained accuracy answer different questions. |
| Comparing E1 and E2 | Compare them because angle, device and cradle match, then name all three improved metrics. | Say E2 proves whole-range joint control. | The records cover one angle and one support configuration only. |
| Reading E4 | Preserve the no-cradle configuration and report it separately. | Treat support as cheating and rank E4 directly against E2. | Support is part of what was measured, not a moral attribute. |
| Using the worksheet | Calculate from supplied records while remaining still or using text-to-speech. | Try the pictured angle to make the numbers feel meaningful. | This supplied exercise deliberately uses the lesson’s no-attempt route and authorises no movement or joint challenge. |
| Making a safety claim | State that device accuracy does not establish tissue integrity or injury prevention. | Call five in-band samples proof of a bulletproof joint. | Performance at one recorded angle cannot certify tissue safety. |
Common mistakes and fixes
| Mistake | Fix |
|---|---|
| Signed deviations are averaged and cancel to a deceptively small value. | Take the absolute value of every sample before adding and dividing by five. |
| Zero arrival error is used as the entire control score. | Calculate mean absolute error from target and in-band count from all five samples. |
| E2 and E4 are ranked without recording support. | Mark support mismatch and keep the no-cradle record separate. |
| A strong 120-degree result is generalized to the 90-degree row. | Apply the angle-specific boundary and report E3 on its own terms. |
| The learner attempts an end-range position to fill an imagined missing input. | Use only the complete fictional table; choose no attempt and stop if the worksheet is becoming physical. |
Evidence boundary
What the tutorial may—and may not—claim.
Supportable claim
End-range performance can improve, usually in an angle- and task-specific way; broad transfer is not established.
Measurement boundary
Angle-specific torque or task accuracy measures tested capacity in that position, not tissue integrity or safety in every movement.
Own impossible joint angles
MetricAccuracy and force at a declared angle
BoundaryOne-angle strength cannot prove whole-range control or tissue safety.
Negative and limiting findings
- Isometric strength gains were limited to the trained and adjacent angles.
Prohibited wording
- Bulletproof joints
- Own every range
- Loaded stretching repairs injuries
- End range prevents all injury
