Rehabilitation Assessment Technology Reading Notes

1. Concept

Rehabilitation evaluation refers to the objective, qualitative or quantitative description of the functional status and level of the sick, injured or disabled, and the results The process of making reasonable explanations is also called functional assessment.

2. Content

Rehabilitation assessment is divided into clinical assessment and functional assessment.

Functional assessment includes individual functional assessment and overall functional assessment

Examination content includes:

General information

Chief complaint: The patient’s most important complaint Main symptoms or signs and duration of onset

History of current illness

Past history

Personal history

Marital and childbearing history

Family history

Physical examination

Functional assessment: physical function, speech (communication) function, mental and psychological function and social adaptation function. Physical function includes muscle strength assessment and muscle tone assessment. , joint mobility assessment, gait analysis, balance and function assessment, and hemiplegic motor function assessment.

3. Purpose

To clarify the nature of functional impairment

To clarify the scope of functional impairment

To clarify the degree of functional impairment

Clarify rehabilitation goals and treatment plans

Evaluate rehabilitation treatment and prognosis judgment

4. Reliability

Reliability (reliability), also known as dependability, It refers to the degree of repeatability and stability of the assessment method, expressed by the reliability coefficient (coefficient).

Including intra-group and inter-group reliability tests.

The intra-group reliability test is a test where the same group of subjects uses the same assessment method to conduct two assessments at a certain interval. It tests the impact of the time interval on the stability of the assessment results. It is also called test-retest reliability. Spend.

The inter-group reliability test is the consistency of different evaluators using the same evaluation method to evaluate the same group of patients to estimate the objectivity of the evaluators.

5. Validity

Validity (validity), also known as accuracy, refers to the authenticity and effectiveness of the measurement method. It means that the evaluation effect of a set of evaluation methods meets the purpose of evaluation. extent.

The characteristics of the subject's dysfunction indicated by the assessment

Reflect the severity of the dysfunction

Method: Correlation validity (correlation check) gt ; Construct validity (existing assessment methods) gt; Content validity

6. Sensitivity

Sensitivity means that the selected assessment method should be sensitive to the content being assessed, that is, it can measure Produce meaningful changes in a subject's characteristics, behavior, or degree.

True positive? / (false negative, true positive) A criterion for test validity

7. Specificity

Specificity refers to the application of a specific method When assessing groups without a certain functional impairment, there may be true negatives (no functional impairment and the assessment results confirm it) and false positives (no functional impairment but the assessment results show that there is a functional impairment).

True negative? / (False positive, true negative) A standard for testing validity

1. Qualitative assessment

Grasp the "quality" of the research object

p>

2. Quantitative assessment

Quantitative assessment of grade data: muscle strength assessment, life activity assessment, various scales, etc.

Measurement data assessment: joint mobility ( °), stride length (cm), muscle strength test (N.m)

3. Workflow

Initial assessment: Assessment upon admission

Mid-term assessment: Patients who recover quickly are recommended to be assessed once every 1 to 2 weeks; for patients who recover slowly, they can be assessed once every 3 to 4 weeks

Terminal assessment: assessment before discharge

Rehabilitation medicine The main purpose is not to pursue a "cure" of the disease, but to focus on restoring the patient's functions to the maximum extent so that the patient can return to society.

The degree of independence is divided into four levels:

Completely independent (no dependence required)

Mostly independent (a small amount of dependence)

Small Partially independent (mostly dependent)

Unable to be independent (completely dependent)

Note:

For the correct assessment method, the measured value must be compared with the normal reference value Contrast, compare the left and right sides of the body

Master the appropriate assessment time, and the time for each assessment should not be too long to avoid causing patient fatigue

Handle the communication between doctors and patients, and actively win over patients and their families Support

Let the same evaluator evaluate the patient's functional status, and it is not appropriate to change the evaluator during the evaluation at different periods

To prevent accidents

1. Human Morphology Measurement

Physical fitness assessment

Muscle strength: refers to the ability of muscles to overcome internal and external resistance when working, static strength and explosive strength

Endurance: refers to the human body The ability to perform muscle work for a long time

Speed: reaction speed, action speed and displacement speed of periodic movements

Balance and coordination: Balance refers to the balance of the human body, no matter where it is, at rest, The process of automatically adjusting and maintaining posture when exercising or under the action of external forces; coordination refers to the human body's ability to produce smooth, accurate, and controlled movement. It requires movement to have a certain direction, rhythm, appropriate distance, speed, and movement. Muscle strength to accurately reach the sports target.

Sensitivity: refers to the human body's ability to quickly, accurately and coordinately change body posture, switch actions and adapt to various circumstances under various complex situations. It is the comprehensive expression of motor function and physical fitness in sports activities. Generally, there are visual inspection method and game measurement method.

2. Evaluation of joint mobility ※

Range of motion (ROM), also known as joint range of motion, refers to the movement of the distal end of the joint toward or away from the proximal end , the angle between the new position reached by the distal bone and the proximal bone.

During the measurement, except for the forearm rotation test, when the palm is in the sagittal plane, which is 0°, all other joints are divided into active joint mobility, which is 0° when the limb is in the anatomical position.

and passive range of motion.

Active joint mobility reflects the degree of joint activity and muscle strength; passive joint mobility reflects the nature of the joint at the end of the activity.

Those who are unable to move actively but have normal passive movement are often caused by nerve paralysis or muscle or tendon rupture;

Those who are partially limited in both active and passive movements are often caused by joint stiffness , mainly caused by intra-articular adhesion, muscle spasm or contracture, or long-term joint immobilization;

Those who are unable to move actively or passively often have joint stiffness, indicating that there is bone between the bones that make up the joint. or strong fiber connections.

First evaluate the active range of motion of the joint, then evaluate the passive range of motion, and compare it with the evaluation results of the corresponding joints on the contralateral side.

1. Basic concepts

Muscle strength refers to The maximum force produced when a muscle or muscle group contracts, divided into static muscle strength and dynamic muscle strength.

Muscle strength assessment refers to the assessment of the contraction force of muscles or muscle groups during active exercise, and is used to evaluate the functional status of muscles.

2. Classification of muscles

Prime mover muscles: also called agonist muscles, are the main action muscles that initiate and complete an action.

Antagonist muscle: A muscle that acts in the opposite direction to the prime mover, that is, a muscle that opposes the direction of movement and acts as an antagonist.

Fixator muscles: In order to give full play to the role of the prime mover, the bones at its relatively fixed end must be fully fixed. The muscles involved in the fixation are the fixator muscles.

Synergist muscles: Cooperate with the prime mover muscles and contract together with the prime mover muscles or muscle groups

3. Types of muscle contraction

Isometric contraction: only A form of contraction in which muscle tension changes while the length remains essentially unchanged. The tension is equal to the applied resistance and the muscle length remains unchanged.

Isotonic contraction: A form of contraction in which only the length of the muscle changes but the muscle tension remains basically unchanged.

Concentric contraction: It is characterized by the muscle starting and ending points being close to each other and the muscle length shortening, the tension is greater than the external resistance, and the muscle length is shortened, such as swinging the arm, raising the leg, etc.

Eccentric contraction : Specifically, the starting and ending points of the muscles are far away from each other and the muscle length is increased. The obstacle is less than the external resistance and the muscle length is lengthened, such as squatting, running downhill, jumping from high places, etc.

4. Indications and contraindications

Contraindications:

Local inflammation, joint effusion, joint instability, acute sprains

Severe local pain

Severe heart disease or high blood pressure

5. Precautions

Necessary demonstration and patient cooperation

Reduce interfering factors, such as pain, fatigue, clothes that are too thick or too tight, etc.

Avoid adverse reactions, such as increased blood pressure, increased heart load, etc.

Avoid compensatory exercise

6. Result recording and analysis

Result record:

Muscle strength level: 0 ~ 5, indicate " ", "-" when necessary

If the ROM is limited, the range should be recorded

If there is spasm, contracture, pain, etc., it should be noted

Optimum force angle: the corresponding joint angle when peak torque is generated? ==gt; Joint angle torque curve

Time to reach peak torque: the time from the beginning of muscle contraction to reaching peak torque, the unit is seconds (Explosive force) ==gt; Time torque curve

Torque acceleration capability (explosive force): the amount of work done in the first 1/8 s of the torque, or the area covered

Peak Torque to body weight ratio

1. Basic concept

Muscle tone refers to a sustained, small, involuntary contraction of muscle tissue in a resting state.

The essence is? Tonic stretch reflex

2. Abnormal muscle tone

Increased muscle tone: spasm (speed-dependent, the higher the speed, the more prone to occur)/stiffness (compared with spasticity, stiffness is relatively continuous and does not depend on the speed of passive movement, that is, no speed dependence)

Hypotonia: muscle relaxation and weakness, passive movement resistance is weakened or even Disappear

Dystonia: Muscle contraction is fast or slow, repetitive movements, twisting deformities and a series of involuntary movements, etc. Muscle tone is usually unpredictable

1. Basic concepts

Coordination function: Coordination is also called *** Economic. Refers to the ability to produce smooth, accurate, and controlled movement, which requires appropriate speed, distance, direction, rhythm, and muscle strength.

Coordinated movement: refers to the fact that under the control of the central nervous system, muscle groups related to a specific movement or action work together in a certain spatio-temporal relationship, resulting in smooth, accurate, and controlled movement.

Coordination dysfunction: Coordination dysfunction is also called dystaxia. Coordination dysfunction refers to abnormal movements characterized by clumsy, unbalanced, and inaccurate movements.

2. Coordination dysfunction and damage to the central nervous system

Characteristics of coordination dysfunction in cerebellar insufficiency

Poor spacing: drawing circles or horizontal 8 Word test

Intention tremor: The closer the hands and feet are to the target, the more obvious the tremor

Postural tremor

Alternating dyskinesia: difficulty completing rapid alternating movements

Motor dissociation: When completing an action, it is not a smooth movement, but a series of motor components

Coordination dysfunction characteristics of basal ganglia insufficiency (Parkinson, sequelae of stroke) ※

Resting tremor: tremor at rest, reduced after activity

Akinesia: difficulty in initiating movement

Athetosis: extremities, trunk, and face Slow, involuntary twisting movements of parts

Here we take part of the concept of coordination function assessment - fine coordination dysfunction, and set a level for coordination within the plane range. Standards, not for assessment of coordination dysfunction

1. Motor control dysfunction caused by damage to the central nervous system

Abnormal muscle tone.

The spasms mainly occur in the antigravity muscles, with flexor type spasms in the upper limbs and extensor type spasms in the lower limbs

Abnormal movement patterns. Synkinesis is distinguished from dissociation

An abnormality in reflexes. In the early stage of stroke, the muscle tone of the affected limb is low and the reflexes are lost; in the middle stage of stroke, the deep reflexes are hyperactive, and joint reactions of spasm and synkinesis occur.

Movement of the unaffected side causes involuntary movement of the affected side, and movement of the upper limb causes involuntary movement of the lower limb
