Intro To Functional Task and Movement Analysis

Task Analysis - What type of task is it?

(taxonomy)

  • Stable (static)/Dynamic (moving)

  • Discrete/serial/continuous

  • UE manipulation or no UE

Environmental Factors

What is the typical environment this task is performed in?

Open vs. Closed

What are the regulatory environmental features that impact?

Environmental regressions and progressions (for retraining)

Closed → Open

Regulatory features

Non-regulatory features

Movement Considerations

Symmetry: Is this a task that is expected to be symmetrical or asymmetrical?

If asymmetrical (dissociated movement) task, it is expected that the person can perform the task equally well with both sides of the body?

Alignment: What body position (join/skeletal alignment) is needed for task performance?

What is the typical BoS throughout the task?

What muscle flexibility/joint and spine mobility is needed?

Direct: What direction do body parts move for the task?

What muscles need to activate to move in this direction

Amplitude: How much movement is expected for typical task performance at each body part?

What muscles need to activate for this?

What ROM/muscle flexibility is needed to allow this movement

Postural Control/Stability: What are the demands for stability for the task?

Does the BoS change during the task

How many body parts need to be controlled during the task?

What physical properties affect stability for the task?

Temporal Sequencing - Stages of movement

  1. Initial conditions

  • Starting posture

  • Alignment, BoS, Stability

  • Primary muscles active?

  1. Preparation

  • Sensory input - perception of environmental considerations and body position

  • Cognitive - comprehension of instruction and task requirements for motor planning

  • Personal factors - Motivation; interest; fear

  1. Initiation

  • The instant when displacement of the body segment begins

  • Direction of weight shifts and body segment is displaced

  • Primary muscles active?

  1. Execution

  • Period of actual segment movement

  • Direction, Amplitude, Speed, Stability

  • Primary muscles active?

  1. Termination

  • The instant when motion stops

  • Ending posture

  • Alignment, BoS, Stability

Atypical Movement Analysis

  • Hypothesize what INDIVIDUAL factors / impairments could be impacting movement from your knowledge of what is needed for typical task performance

  • Consider:

  • Motor/Action: Musculoskeletal; neural control; other systems

  • Sensory/Perception

  • Cognitive

  • Personal factors: Motivation, interests, experiences

Temporal Sequencing

  • Where is the temporal sequence is the atypical movement observed?

  • What is different than expected at that stage
