Lee Silverman Voice Treatment Versus Standard Speech Therapy Versus Control in Hypophonia Rehabilitation in MS
Lee Silverman Voice Treatment Versus Standard Speech and Language Therapy Versus Control in Multiple Sclerosis: a Randomized Controlled Trial
The aim of the study is to identify the most effective method of intervention to reduce hypophonia in PwMS (Patient With Multiple Sclerosis), as a way to optimize the speech-therapy treatment based on scientific evidence. In the previous AB study, we aimed to verify the efficacy of LSVT LOUD® in PwSM: in the present study we will compare different treatment in a larger sample.
Half of the participants will follow the LSVT Loud program, the other half will follow usual care rehabilitation programs.
The results of these groups will be compared with an historical cohort of no treatment patients.

Detailed Description
The descriptive studies showed that voice problems, in particular hypophonia, are present in 45% to 91% of patients with multiple sclerosis and may constitute a limitation in social life participation. Although voice, speech and communication are significant aspects for the biopsychosocialwell-being and life quality, only 2% of the PwMS had received any speech therapy and, at the same time, few studies assessed the effects of speech treatment for PwMS.
In according to the taxonomy of voice therapy, the conventional treatment may include direct interventions such as vocal function and modification of respiratory function.
The LSVT LOUD® treatment is a standardized, research-based speech treatment protocol with established efficacy for Idiopathic Parkinson Disease (IPD) and is well described in a large number of studies. Subsequently, further studies supported the efficacy of LSVT LOUD® in voice rehabilitation in various neurological diseases, including Multiple Sclerosis. In the study of Sapir et al., only two women were treated with LSVT LOUD® and the authors concluded that intensive phonatory-respiratory treatment can produce clinically significant and long-term improvement in vocal function in PwMS. These findings are consistent with suggestion that intensive training can improve function in those parts of the body that are prone to fatigue and that vocal training probably minimizes disuse atrophy and increases muscle strength and coordination.
The content and dose of the SLT (Speech Language Therapy) of dysphonia in MS is poorly defined within the published literature and we did not find any meta-analyzes or guidelines that suggest instructions for therapists.
The purpose of this project is to identify the most effective method of intervention to reduce hypophonia in PwMS, as a way to optimize the speech-therapy treatment based on scientific evidence. The data in literature suggest that LSVT LOUD® may be functional for these aims, although there isn't broad-based study with PwSM.
Fourty Persons with Multiple Sclerosis will be randomly allocated to an experimental group (Lee Silverman Voice Treatment - LSVT LOUD® method) or to a control group following usual care rehabilitation programs.
Also an historical cohort of untreated patients was considered (voice assessment: baseline, after 4 weeks, FU-Follow Up at 6/12 months).
Data collection in both groups will be performed at baseline, after 4 weeks of treatment and after 6-12 months up to the end of the rehabilitation program (FU). In order to evaluate the perceptual impact of the treatment, GIRBAS and VHI will be proposed.
The acoustic variables will be recorded with the software PRAAT: SPL (Sound Pressure Level) of a sustained /ah/, SPL of functional sentences, maximum phonation time, SPL of 1 minute monologue. In addition, the following values were taken in the minute of spontaneous speech: Jitter, shimmer, fundamental frequency, maximum frequency and minimum frequency. The type of MS, Expanded Disability Status Scale (EDSS) , demographic data, disease duration, presence of postural and respiratory problems, presence of depression (Beck Depression Inventory-II - BDI II) , pharmacological treatment and cognitive status (Brief Repeatable Battery of Neuropsychological Tests) will be considered.

Intervention / Treatment |
---|---|
Experimental: Lee Silverman Voice Therapy
LSVT LOUD® is a therapy program which requires four sessions per week for 4 weeks by a speech and language therapists with a certification in Lee Silverman Voice Therapy.
Each session lasted 50-60 min.
|
LSVT LOUD® comprises maximum effort non-speech and speech drills.
The non-speech drills include the production of 15 sustained 'ah' phonation at high volume and pitch glides (5 repetitions moving from modal pitch to high pitch and 15 repetitions moving from modal pitch and going down on production of sustained 'ah').
The speech drills utilize a hierarchy of speech tasks moving from single words through phrases and onto conversational speech to generalize
|
Active Comparator: Conventional Treatment
The content and dose of standard SLT is poorly defined within the published literature.
For this reason, the standard therapy intervention will encompass all SLT techniques that are not LSVT®.
Treatment will be individualized and may include any of the following: exercises targeting respiration, phonation, articulation, behavioral strategies to reduce prosodic abnormality

Voice Handicap Index (VHI) is a self-assessed standardized 30-point questionnaire, which includes items on the impact of the voice disorder on daily life.
The questionnaire is divided into three subscales covering functional, emotional and physical aspect of voice disorders.
Each answer is graded 0 to 4 depending on the frequency of the difficulty: 0 no difficulties, 1 almost never, 2 sometimes, 3 almost always, 4 always.
