Task Oriented Approach

What are the initial parameters in Body Weight Support Training?

A
  • Intensity: 40% of body weight, no incline, low speed (0.5 mph)

  • Frequency: 5 days/wk

(progress to ↑ speed, incline duration, ↓ amount of BWS)

Q

Task Oriented Approach

how does a brain injury patient learn not to use a limb?

A

brain injury → unsuccessful motor attempts → stops using the limb → brain “learns” not to use the limb

The task oriented approach looks at and treats motor behavior by focusing on:

Q

Task Oriented Approach

when is functional independence achieved?

A

when the patient is able to perform a functional task in many environmental contexts

ex: when the patient is able to get out of many types of beds and in many environmental contexts

Q

Task Oriented Approach

what is Accelerated Skill Acquisition Program?

A
  • Uses skill, capacity, and motivation
  • Combination of task-specific and skill-based/impairment-mitigating training with embedded patient-centered motivational enhancements

Q

Task Oriented Approach

what is task practice?

A
  • Patient performs functionally based activities for 15-20 min
  • PT provides global KR feedback at the end of the practice period.
  • Functional activities are made more challenging by changing various parameters

Q

Task Oriented Approach

what is the Modified Constraint Induced Movement Therapy?

A
  • is a less intense protocol than original CIMT;
  • 30 min sessions instead of 3-6 hours.
  • And restraining 5 hours per day instead of 90% of wake hours.

Q

Task Oriented Approach

Describe 3 of the task-oriented approach basic principles

A
  • Work on functional tasks that are meaningful to the patient, rather than on movements patterns (for cortical changes to occur).
  • Vary practice conditions with emphasis on flexible task performance.
  • Active participation/problem-solving by the patient.
  • Clear identification of the goals to the patient.
  • Feedback as needed (manual guidance only as needed)
  • Early intervention.
  • Specificity of training.

Q

Task Oriented Approach

What is the task-oriented approach based on?

A
  • Theories of motor control (systems, reflex-hierarchical)
  • Understanding kinetics and kinematics
  • Neuroplasticity
  • Theories of motor learning (Fitts and Posner)
  • Role of the environment
  • There is a shift from facilitation and inhibition towards the relearning of motor control necessary for specific functional tasks
17
Q

Task Oriented Approach

what is shaping?

A
  • Shaping is a method of operant conditioning (Skinner behavioral technique) by which successive approximations of a target behavior are reinforced. Only small improvements are required for success but the challenge is increased steadily.
18
Q

Task Oriented Approach

a training program to be considered tactile task-oriented, it must be:

A

challenging, progressive and optimally adapted, and active participation

  1. Challenging enough to require new learning and to engage attention to solve the motor problem;
  2. Progressive and optimally adapted such that over practice, the task demand is optimally adapted to the patient’s capability and the environmental context; not too simple or repetitive to not challenge, and not too difficult to cause a failure of motor learning or a low sense of competence,
  3. Interesting enough to invoke active participation to engage a “particular type of repetition” referred to as “problem-solving.”
19
Q

Task Oriented Approach

walking is most often performed in conjunction with other tasks, such as

A

carrying loads, scanning the environment, and engaging in social interactions.

20
Q

Task Oriented Approach

describe the steps of the Motor Relearning Program:

A
  1. analysis of tasks (observation, comparison, identify missing components)
  2. practice of missing components (using verbal, manual, and visual FB)
  3. practice entire task (avoid learned errors and learned non-use)
  4. transfer of training
21
Q

Task Oriented Approach

Within the ICF, mobility is considered both an….

A
  1. activity (e.g., a task performed by an individual)
  2. and a domain of participation (e.g., the societal level of functioning).

This can make it difficult to classify tests of mobility function. In this chapter, a mobility test performed in a standardized clinical environment is classified as an activity measure considered to capture the ICF’s concept of capacity.

22
Q

Task Oriented Approach

In a task-oriented approach, examination of mobility function analyzes performance at three levels

A
  1. the functional-task level (10 m walk test, etc)
  2. the essential strategies used to accomplish the requirements of mobility (observational)
  3. the underlying sensory, motor, and cognitive impairments that constrain mobility.
23
Q

Task Oriented Approach

the relationship between impairment and gait parameters is very complex, and depends on many factors, including the

A

type and extent of impairment, the functional level of the patient, and the capacity for compensation by other systems.

24
Q

Task Oriented Approach

Describe three of the task oriented approach assumptions:

A
  • Normal movement emerges from the interactions between many systems.
  • Movement is dependent upon interactions among the individual, the task, and the environment.
  • Mvmt organized around a behavioral goal.
  • Sensation is not only for stimulus/response, but essential for predictive and adaptive control.
  • What is observed in a pt with a motor cortex lesion is the effort of the remaining system to participate.
  • The brain is plastic and can recover.
25
Q

Task Oriented Approach

name 4 clinical applications of the task-oriented approach:

A
  • Motor Relearning Program
  • Body Weight Support Training
  • Accelerated Skill Acquisition Program (ASAP)
  • Constraint-Induced Movement Therapy (CIMT)
26
Q

Task Oriented Approach

Body Weight Support Training progression strategies:

A

Standing training → step training → step adaptability training (change speed, incline, and duration) → overground walking training → community integration

27
Q

Task Oriented Approach

what are the two rationale mechanism underlying Constraint Induced Movement Therapy?

A
  1. Overcome learned non-use
  2. Use-depended brain/cortical plasticity
