Lessac-Madsen Resonant Voice Therapy
Transcript of Lessac-Madsen Resonant Voice Therapy
Foundations are the "what", "how,"
"if" of voice therapy
WHAT: Direct Therapy
HOW: Learning Process
IF: Indirect Therapy
All inclusive therapy that addresses vocal hygiene, voice modification, and post-therapy self care.
Basic training gesture (RVT)
Target behavior on simple phonemes
Target behavior in conversational speech
Vocal hygiene program
-RVT (LMRVT) can be applied in a clinical setting and is useful to patients who experience difficulties with their voice. The goal is to achieve sound volume through resonance.
- Research has shown that this technique is effective for voice clients; most studies done using teachers.
- ENT evaluation and diagnosis is required before implementing this therapy approach to ensure efficacy.
- Be sure to use clinical judgment, ENT evaluation report, SLP evaluation report, and evidence- based practice to determine which vocal parameter client is having difficulty and if LMRVT is most appropriate therapy for that client.

- Interested in training?
Webinars available for students and SLP's.

Thank you to Ms. Kimbrough for an amazing learning experience!
• Developed by Dr. Katherine Verdolini Abbott in the early 2000s
• Dr. Verdolini Abbott named the technique after her two mentors, Dr. Arthur Lessac and Dr. Mark Madsen
• LMRVT corrects both hypo- and hyperadducted vocal fold posturing by guiding vocal behavior toward barely-abducted or barely-adducted laryngeal posturing
• After a series of body stretches, the patient is guided through full-body introspection and observation to produce their best resonant voice
Stage 1: Neck stretches and Vocal Warm Ups
Stage 2: Voiced and Voiceless Contrasts
Stage 3: Phrases
Stage 4: Combining phrases in to paragraphs
Stage 5: Targets controlled conversation with forward focus
Stage 6: Environmental manipulation to challenge the client to use forward focus in loud places
Stage 7: Adding emotional manipulation to continue resonant voice to continue laughter, anger and other emotions.

Muscle Tension Dysphonia (MTD)
Hypofunctional voice disorders
Mild vocal atrophy and paralysis
Laryngeal Carcinoma (Following Radiation)
Neurologic voice disorders
Immediately after a hemorrhage
Large Glottal insufficiency
Chen, et.al (2007) showed that after resonant voice therapy the severity of the following voice symptoms and signs were reduced:
- hard attack
- glottal fry in auditory perceptual judgments
- the severity of vocal fold pathology
-vocal fold closure in videostroboscopic examinations
- phonation threshold pressure
- the score of physical scale in the Voice Handicap Index
- The speaking Fo, maximum range of speaking Fo, and maximum range of speaking intensity were significantly increased after therapy.
