Effects of IOPI on Swallowing Function and Functional Status in Geriatric Patients

September 29, 2021 updated by: Choo Wan Ling, Khoo Teck Puat Hospital
This project is an exploratory study that aims to investigate the effects of IOPI therapy on the swallowing function and tongue strength of geriatric patients in a geriatric ward in an acute hospital. Its secondary aim is to investigate the correlation between IOPI readings and functional status. The result of this study could help to improve current practice of dysphagia intervention in the geriatric population. If results are significant, there will be research evidence to put forth a change to work processes for speech therapists. IOPI will be more widely used in the clinical context and will then result in better functional outcomes.

Detailed Description

In recent years, there have been increasing evidence that tongue strengthening exercises have the ability to improve tongue muscle strength and tongue muscle thickness in the geriatric population. These improvements have a direct impact on the oral phase of swallow, specifically resulting in better orolingual manipulation and propulsion, and increasing intra-oral pressure for better bolus clearance. Reduction in tongue strength and other swallowing parameters can lead to swallowing disorder known as dysphagia. In the healthy ageing population, weakness in swallowing muscles is termed presbyphagia. Geriatric patients have an even higher chance of transitioning from presbyphagia to dysphagia when they become acutely unwell. Studies have also shown that deterioration of the whole-body muscle strength is associated with poorer oral function. Additionally, other studies have also shown that a lower isometric tongue strength might represent diminished functional reserves, which may increase the risk of dysphagia once an insult to the body occurs. There is also evidence that people who have episodes of aspiration have significantly weaker tongue strength at both the anterior and posterior regions. Thus, frail geriatric adults who have weaker skeletal muscles are at a higher risk of developing dysphagia. The tongue is amendable to therapy but current practices in Singapore lack an objective measure. Conventional dysphagia oromotor exercises employ the use of a tongue depressor. This method lacks a quantifiable measure to track outcome and is quite subjective to individual therapists. There is also a lack of practice guideline on recommended resistive load and frequency of exercise in the geriatric population in the acute setting. Other than outcome measures and practice guidelines, there is also a lack of research investigating the correlation of tongue strength and functional status. A few studies have explored the effects of different resistive load used in tongue strengthening exercises, although it was recommended to use a resistive load between 60% to 80% for more positive and extrinsic feedback, and for target population with a lower frustration threshold. Studies also used a longer timeframe of 3-4 weeks of rehabilitation to attain significant effects from skeletal muscle exercise. This, however, is not realistic in the acute geriatric setting in Singapore where the mean length of stay is 10 days. Thus, this study is an exploratory study to investigate the efficacy of using IOPI in this population to improve swallowing function and tongue strength. This study also aims to investigate if a correlation exists between IOPI reading and functional status.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: Control Group
Tongue depressor exercise protocol for tongue strengthening for control group. Using the tongue depressor, participants will be prompted to stick their tongue out as much as they can and to push hard against the tongue depressor for 10 seconds. They will be required to repeat this action 10 times, constituting one set. They will be asked to perform 3 sets, with 30 secs of rest between each set. Arrange for 5 sessions for a week; sessions can take place on consecutive days.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 5 intervention days
The IOPI device will be used to measure tongue strength at the anterior position on the last day of intervention. This will be compared to the baseline tongue strength collected on the first day of intervention.
5 intervention days
Improvement in score on Functional Oral Intake Scale (FOIS)
Time Frame: 5 intervention days
The speech therapist will rate the participant's FOIS score at the start and end of intervention according to the type of diet that the participant is prescribed.
5 intervention days

Secondary Outcome Measures
