Task and control target Establishes what the biological system is trying to maintain or change and what counts as an instance of control.
Movement and posture goals
Records the task outcome and candidate variables regulated during movement or stillness.
Task-relative success
Record the intended outcome, tolerances, and whether the controlled variable is explicitly instructed or inferred from behavior.
- Is the task to reach a target, regulate contact force, maintain posture, produce a rhythm, or achieve another specified outcome? definition
- Which observable variable and tolerance distinguish success from failure, and what supports treating that variable as controlled? measurement
Episode and context boundaries
Defines the control episode and separates immediate regulation from adjacent processes.
Control episode boundary
Specify episode onset and termination, including preparatory and postural activity where relevant, and distinguish immediate control from retained learning.
- What events delimit preparation, movement onset, task completion, and any subsequent stabilization? boundary
- Does the evidence concern performance in this episode or a retained change demonstrated in later trials or sessions? boundary
Sensorimotor regulation Describes how sensory information and anticipatory processes could support ongoing control.
Feedback and correction
Captures sensory conditions and measurable responses to error or disturbance.
Sensory-dependent response
Record the available sensory channels, their manipulation, and the timing and magnitude of observed corrections without automatically assigning a neural pathway.
- Which visual, proprioceptive, vestibular, or tactile signals are available, delayed, removed, or placed in conflict? measurement
- After a defined disturbance, when does correction begin and how much does it reduce the task error? measurement
Anticipation and preparation
Examines behavior preceding movement or expected disturbances.
Predictive control evidence
Distinguish observations consistent with anticipation from stronger claims about internal models or other predictive mechanisms.
- What preparatory activity or force adjustment occurs before the expected movement consequence or disturbance? measurement
- What comparison with unexpected or differently cued events would distinguish anticipation from a response to an earlier sensory cue? action
Body and effector coordination Represents how the body's available motions and forces are organized to meet the task.
Mechanical contributions
Records body and environmental properties that shape movement and stability.
Neural and mechanical attribution
Separate observed behavior from claims about active neural regulation, passive mechanics, and their interaction.
- Which loads, support contacts, joint limits, and mechanical properties constrain the movement or posture? measurement
- What evidence distinguishes an actively generated correction from a response attributable to passive mechanics? boundary
Coordination and solution variation
Captures relationships among effectors and variation among successful task solutions.
Task-preserving coordination
Record how joints, muscles, or limbs vary together and whether that variation preserves the task outcome; treat proposed synergies as method-dependent interpretations.
- Which combinations of joint motion, muscle activity, or interlimb timing achieve the same task outcome? measurement
- If a synergy is proposed, how is it operationalized and what evidence separates it from correlations induced by task constraints or the analysis method? definition
Evidence, performance, and adjustment Connects measurements and theoretical accounts to defensible judgments and next actions.
Performance and tradeoffs
Assesses task outcomes alongside timing, effort, variability, and disturbance tolerance.
Conditional performance judgment
Judge control under documented task conditions and explicit priorities rather than ranking movement by a single context-free score.
- How do accuracy, completion time, effort measures, and failure frequency change across the specified task conditions? measurement
- Which bounded change to load, target tolerance, movement speed, or feedback would test the suspected limitation, and what are the stopping criteria? action
Competing control accounts
Records attributed definitions, explanatory assumptions, and discriminating evidence.
Theory-linked interpretation
For each proposed account, record its authors or school, what it treats as controlled, and which observations would favor or challenge it; allow compatible accounts at different explanatory levels.
- Which authors or school supply this account, and what do they posit about representations, feedback policies, body mechanics, or organism-environment coupling? provenance
- Which feasible observation would separate the candidate accounts, and which current observations remain compatible with more than one? action

What it is Filled
Motor control is the process by which the nervous system, interacting with the body and environment, regulates posture and movement to meet task demands.
In scope
- Task goals, controlled variables, and criteria for successful movement or posture
- Movement preparation, action selection, initiation, coordination, and termination
- Sensory feedback, predictive control, and responses to disturbances
- Coordination across effectors under biomechanical and environmental constraints
- Task-specific control performance and competing explanations of observed behavior
Out of scope
- Electrical motor controllers, drive electronics, and industrial motor regulation
- Motor learning as relatively lasting acquisition or retention of skill
- Anatomical descriptions of neural circuits, muscles, and joints independent of their control roles
- Disease classification, clinical diagnosis, and treatment prescriptions
- General cognition or decision-making without a specified movement or posture task
Why it exists Filled
Enable an agent to describe how a biological system organizes movement and posture, assess control relative to a task, and identify justified observations or adjustments.
Distinguishing features Filled
- An instance must involve organizing or regulating biological movement or posture; holding still against a disturbance can qualify.
- A movement trajectory alone describes motion; a motor-control account additionally identifies the task, constraints, and candidate processes producing or correcting it.
- A change within a trial can concern motor control, while a claim of motor learning requires evidence of persistence beyond immediate performance.
- Successful coordination need not imply a single central command: the account must distinguish neural contributions from body mechanics and environmental interactions.
- A controller regulating an electric motor belongs to the engineering sense of the term and requires a separate scope decision.
What robots and AI may and may not do Filled
Must not
- Diagnose a movement disorder from video or sensor data without a clinician.
- Push a patient beyond the limits a therapist has set.
- Share a person's movement or gait data without consent, as it can reveal health and identity.
Only with a human decision
- Changing a rehabilitation plan.
- Using movement data in decisions about a person's fitness to work or drive.
May
- Explain how the nervous system controls posture and movement, citing research.
- Support rehabilitation exercises a clinician has prescribed and report progress.
Moral aspects Filled
- Movement data can reveal illness before a person chooses to disclose it.
- Rehabilitation goals should reflect what matters to the patient.
Who is affected
- Patients in rehabilitation
- People with movement disorders
- Athletes
Owners Filled
Steward
Nobody owns the process; clinicians answer for its assessment in each patient.
