# Lessac Madsen Resonant Voice Therapy Training

Katherine Verdolini Abbott (“Kittie”) is a professor at the University of Delaware who specializes in voice evaluation and treatment. She will train professionals in Lessac Madsen [Resonant Voice Therapy](https://alsuprun.com/) (LMRVT).

 LMRVT focuses on resonant voice behavior that optimizes loudness intensity VF impact stress and configuration, thus putatively protecting the vocal fold from injury. Clinical practice and unpublished experimental data strongly support that this voicing pattern heals phonotraumatic laryngeal lesions.

 

## Training

 The clinician uses the scan-gel-show-tell principle, asking for perception of the region in question (head, neck shoulders, jaws and back), demonstrating how it feels and what is required, then physically manipulating the area until the patient exhibits his or her best representation of the resonant voice. The therapist also guides the patient through full body introspection and observation.

The therapist emphasizes the importance of hygiene and helps patients develop their own post-therapy program, stressing what is important to them.

 LMRVT is based on the biomechanical goal of guiding vocal behavior toward barely ab/adducted laryngeal fold position, which multiple studies have indicated optimizes loudness intensity and VF impact stress with the least amount of phonation effort. Functional goals, such as increasing the loudness of one’s voice and reducing recurrent phonation effort, are by-products of this focus, rather than primary treatment goals. Patients are not instructed to speak in a loud voice until the therapist advises them that they are ready to do so, in order to prevent further phonotrauma.

 

## Exercises

 This five-day training offers speech-language pathologists the opportunity to understand and learn the Lessac Madsen [Resonant Voice Therapy](https://alsuprun.com/) (LMRVT) method. Its theoretical framework focuses on three broad parameters: the “what” of training (the biomechanical target and its biological consequences); the “how” of training (how people acquire and habituate new physical behaviors); and the “if” of training (factors that impact patient engagement and compliance with therapy).

This approach to voice therapy is based on motor learning research that shows focusing on the mechanics of a new skill impairs its immediate performance and long-term retention.

 LMRVT differs from the Casper-Stone Confidential Flow Therapy (CSCFT) method in that it favors a barely adducted larynx during phonation as compared to CSCFT’s preference for slightly greater abduction with semi-occluded laryngeal opening. This adducted laryngeal position allows for good vocal output and minimal impact stress, which is thought to protect against voice injury.

 One limitation of LMRVT is that some clients may be inspired to attempt loud speech outside the clinic before they fully master the resonant voice behavior. This may result in further damage to the vocal cords, and it is therefore important for therapists to use caution when guiding such patients in this direction.

 

## Treatment

 Lessac Madsen [Resonant Voice Therapy](https://alsuprun.com/) (LMRVT) is a comprehensive, evidence-based approach to the treatment of phonotraumatic vocal fold lesions including nodules and polyps. It is based on the principle that sensory processing is critical to healing a voice disorder, and that the barely ab/adducted laryngeal posturing that is facilitated in LMRVT is the optimal configuration for voicing with maximum loudness intensity and minimal adduction stress (Verdolini et al., 1998). Clinical experience and unpublished experimental data also suggest that resonant voice production results in a lower risk of phonotrauma than adducted or even neutral speech behaviors (Verdolini, personal communication, July 12, 2005).

 The clinician guides the patient through full-body introspection and observation and then uses physical manipulation to achieve the best representation of the desired resonant voice quality. Whenever possible, the clinician refrains from mechanical verbal instructions in accordance with research in motor learning indicating that they impair both immediate and long-term retention of the new motor skill.

 The clinician builds a hygiene program tailored to each patient that takes into account their unique lifestyle and post-therapy needs in order to increase the likelihood of patients continuing to practice resonant voice outside of the clinic. This includes hydration, which is important for maintaining adequate lung pressure for adduction and to minimize reflux symptoms that can be caused by hyperadduction and high amplitudes of vibration (Verdolini & Titze, 2002). The clinician may also treat other symptomatic aspects of the voice, such as breath support, in order to facilitate the healing of a phonotraumatic lesion.
