The Importance of Oral Mechanism Exam in Speech Therapy
A Guide for SLPs
An oral mechanism exam is a crucial component of comprehensive speech and language evaluations. As speech-language pathologists (SLPs), understanding the structure and function of the oral mechanism can provide key insights into articulation difficulties, feeding challenges, and resonance disorders. This assessment not only identifies underlying physical or neurological factors impacting speech but also guides effective treatment planning. Please don't skip it!
Why Is An Oral Mechanism Exam Important?
Speech production is a complex motor activity that involves precise coordination of the lips, tongue, jaw, palate, and respiratory system. We know this! Any structural or functional abnormality can affect speech production. To be able to create an effective therapy program, we must know what is going on!
By conducting an oral mechanism exam, an SLPs can:
- Identify Structural Anomalies: Issues like high palatal arches, dental malocclusions, etc..
- Detect Neuromuscular Weakness or Incoordination: Weakness in the tongue or lips that may be affecting speech production
- Evaluate Oral Function for Feeding and Swallowing: The exam can highlight difficulties with feeding and swallowing.
- Differentiate Between Motor and Phonological Based Disorders: This ensures more accurate diagnosis and targeted intervention. This is KEY!
How to Conduct an Oral Mechanism Exam
- Prepare the Materials: Use a flashlight, gloves, tongue depressor, and mirror. Have a checklist or form to record observations.
- Assess Structure
- Lips: Check for symmetry, size, and movement.
- Tongue: Observe for size, shape, range of motion, and strength.
- Palate: Examine the hard and soft palate for structural integrity.
- Teeth and Jaw: Look for dental occlusions or jaw alignment issues.
- Evaluate Function:
- Lips: Ask the client to pucker, smile, and press their lips together.
- Tongue: Request tongue protrusion, lateralization, elevation, and rapid movements.
- Velum: Assess velar movement by asking the client to say “ahh” and watch for symmetrical elevation.
- Assess Reflexes and Sensitivity: Evaluate the gag reflex (gently), tongue strength by pressing against a depressor, and overall sensitivity.
- Assess Breath Support: Assess coordination and breathing patterns as it relates to speech.
Interpreting Results Of Oral Mechanism Exam
After the exam, note any asymmetry, weakness, or abnormal movement patterns. Consider how these findings align with the client’s speech or feeding difficulties. This will help plan treatment as you may need to address weakness, incoordination, structural anomalies, etc.. during treatment.
