Concurrent Apraxia and Dysarthria

By Pam Marshalla

6256176114_2d28fbb290_mQ: Can a child have both dysarthria and apraxia?

From my perspective, yes.

  • I see apraxia as a problem in the perception of speech movements.  This is an input problem.
  • I see dysarthria as a problem in the control (execution) of movement.  This is an output problem.

I believe that children can have one, or the other, or both.

    1. Marie-
      Movements are perceived through tactile and proprioceptive input.
      A muscle contracts or relaxes, and the tactile and proprioceptive systems detect these changes.

      A. Jean Ayres (see reference below) said that apraxia was a problem in the organization of input from tactile, proprioceptive, and vestibular signals, principally those of tactile. The child has poor tactile awareness and discrimination.

      Therefore, I see apraxic children as having difficulty perceiving his own movements as they should be sensed through the skin.
      Therapy, therefore, becomes one of helping him perceive his tactile sensations as he moves. What it feels like to move.

      Cueing systems like PROMPT and others help children cue into these movements, as well as do other approaches like simply gently stretching or patting the skin involved.

      Hope that helps!
