Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: IOPI (Iowa Oral Performance Instrument), a biofeedback device that measures tongue pressure produced in kiloPascals (kPa) using an air-filled bulb.

The training protocol consists of a 6-week regime with the participant doing exercises in their home setting. Each participant will be trained individually by the investigators and different exercises will be instructed. After instruction, the participant will be allowed to take the IOPI home for the length of the study to do the exercises at home.

Participants will also be required to complete exercises independently on two other days each week, which will take 10-15 minutes and will be asked to record these practice sessions in a provided diary.

One of the researchers will contact each participant weekly via Skype to evaluate how the exercises are going and if needed, to adjust some of the exercises. Each of these sessions will span 30 minutes to 1 hour and will take place at a time that is suitable for the participant. Only for the first and last session (which will take about 60 minutes), the participant needs to attend the University of Sydney campus.

Dr Bogaardt is a qualified speech pathologist who is a specialist in the use of biofeedback intervention for patients with dysphagia. All investigators will be required to review the Instructions for Use (IFU) of the IOPI device, and it will be used according to its intended use. Dr Bogaardt will supervise the first 5 sessions using the device to ensure the device is being used correctly according to the IFU.

Statistical methods / analysis
As this is a study for investigating the effects of a home-based IOPI program for people with dysphagia, there is a lack of precedent literature to give an indication of appropriate sample size. Julious (2005) recommends that a minimum of 12 participants is required for pilot studies in order to ensure feasibility and precision of the mean and variance. As this study will include a heterogeneous group of patients with dysphagia based on different etiologies (with four main groups: stroke, PD, MS and other underlying causes), we suggest to include a minimum of 60 patients in this study (15 per group), to allow a 20% drop-out rate.

Data will be presented with the range, mean and median, including standard deviations and variances.
Ordinal data collected will be analysed using the Wilcoxon-Mann Whitney test or the Kruskal-Wallis test, dependent on the number of levels. Categorical data collected will be analysed using the Chi-square test or the Fisher’s exact test. Data correlations will be calculated using Pearson’s correlation coefficient (r). Alternatively, Spearman’s rho (p) will be used if the analysis is non-parametric. Correlation coefficients of less than 0.3 will be considered weak, coefficients between 0.3-0.7 will be considered substantial, and values over 0.7 will be regarded as strong correlations.

Summary
Brief summary
The aim of this study is to investigate the effect of a home-based lingual strength training program using the Iowa Oral Performance Instrument (IOPI) on the lingual strength of patients who experience chronic swallowing problems. Previous studies have found that lingual strength improves following training and therefore it is hypothesized that lingual strength will increase following an at-home IOPI training program. Additionally, the effects of this lingual training on self-reported swallowing, speech, saliva control and quality of life will be assessed, as well as reductions in the burden of cost for the healthcare system.
