Treatments of Acquired Apraxia of Speech "Apraxia"

Active, not recruiting

Phase N/A Results N/A

Trial Description

This study is designed to examine the effects of speech therapy on ability to produce speech sounds in persons with acquired apraxia of speech.

Detailed Description

This study is designed to investigate the effects of Sound Production Treatment (SPT; a treatment for acquired apraxia of speech) on sound production accuracy in persons with chronic apraxia of speech (AOS). Organization of practice (blocked practice or randomized practice) will be manipulated in an effort to determine the most efficacious application of SPT. A combination of group and single-subject experimental designs will be completed with 24 speakers with AOS (2 groups of 12 participants).

Conditions

Interventions

  • Sound Production Treatment Behavioral
    Intervention Desc: A treatment for acquired apraxia of speech. Combines therapist modeling, simultaneous production, articulatory instruction, feedback and repeated practice
    ARM 1: Kind: Experimental
    Label: Arm 1
    Description: two groups will receive treatment
  • Sound Production Treatment (SPT) - Blocked Behavioral
    Intervention Desc: A treatment for acquired apraxia of speech. Combines therapist modeling, simultaneous production, articulatory instruction, feedback and repeated practice
    ARM 1: Kind: Experimental
    Label: Arm 1 - Blocked Practice
    Description: two groups will receive treatment
  • SPT - Random Behavioral
    Intervention Desc: A treatment for acquired apraxia of speech. Combines therapist modeling, simultaneous production, articulatory instruction, feedback and repeated practice - stimuli are practiced in non predictable order
    ARM 1: Kind: Experimental
    Label: Arm 2 - Randomized Practice
    Description: treatment stimuli are practiced in non predictable order

Trial Design

  • Allocation: Non-Randomized
  • Masking: Single Blind (Outcomes Assessor)
  • Purpose: Treatment
  • Endpoint: Efficacy Study
  • Intervention: Crossover Assignment

Outcomes

Type Measure Time Frame Safety Issue
Primary speech production Pre treatment (2-3 week period preceding the start of treatment) , Interim treatment (after 20 treatment session - approximately 7 weeks after the start of treatment), and Post treatment (after another 20 treatment sessions - approximately 15 weeks) No
