COORDINATION
definition
Interference with the function of anyone of the factors which contribute to the protection of a coordinated movement
will result in jerky, arrhythmic or inaccurate movement,
which is said to be inco-ordinated
as the harmonious working together of the muscles is disturbed.
Causes of incoordination
- Incoordination associated with
weakness or flaccidity
of a particular muscle group.
-
- LMN lesion prevents appropriate impulses reaching the muscle.
- Incoordination associated with spasticity of the muscles.
- Incoordination resulting from cerebellar lesions.
Hypertonicity of muscles,
easily fatigued,
inadequate fixator action.
Movement is irregular and swaying.
- Incoordination resulting from
loss of kinesthetic sensation.
Eg. Tabes dorsalis
Frenkel’s exercise

Principles
- Concentration of the attention
- Precision
- Repetition
Technique
• The patient is positioned and suitably clothed so that he can see the limbs throughout the exercise.
• A concise explanation and demonstration of the exercise is given before the movement is attempted,
to give the patient a clear mental picture of it.
• The patient must give his full attention to the performance of the exercise to make the movement smooth and accurate.
• The speed of movement is dictated by the physiotherapist by means of rhythmic counting, movement of her hand, or use of a suitable music.

Progression
• Progression is made by
altering the speed, range and complexity
of the exercise.
• Quick movements require less control.
Alternation in the speed of consecutive movements, and interruptions which involve stopping and starting to command, are introduced.
• Initially a wide range of primitive movements are used emphasizing on large joints then progressing to smaller joints, limitations in range and frequent alteration in direction.

The technique progresses in complexity by
- Increasing the speed of contraction
- Increasing the complexity where more muses get involved.
- Increasing the range of movement during the activity.
- Removing the sensory feedback that is given.
The rate of performance should be slowed with each new addition to a pattern.
Fatigue may occur during attempts for precision and may decrease the concentration of the patient. The patient should therefore have a short rest after two or three repetitions.
