Clinical Trial Summary

The aim of this clinical trial is to explore the effects of chin tuck against resistance (CTAR) exercises on improving dysphagia in stroke patients.

The main aims of this research are:

1. To explore the effects of CTAR exercise on stroke patients with dysphagia, and to perform a clinically implementable evidence-based protocol.

2. Introduce the evidence-based "CTAR exercise protocol" in the care of stroke patients with dysphagia, and test the effects through a randomized controlled trial.

This study is a two-group, pre and post-test, parallel, non-blind randomized controlled trial to test the effectiveness of the "CTAR exercise protocol". Convenience sampling the inpatients of stroke with dysphagia from a regional hospital in southern Taiwan. Eighty participants will be randomized block assignment either to an experimental (n = 40) or to a control (n = 40) group. The experimental group will receive a four-week CTAR protocol and regular dysphagia care. The control group will receive the regular dysphagia care only. In this study, dysphagia-related physiological indicators including functional oral intake scale (FOIS), penetration-aspiration scale (PAS), and modified water swallowing test, video fluoroscopic swallowing study (VFSS), and swallowing improvement rate will be used to evaluate the difference between pre-test and four-week post-test after the intervention. The independent t-test will be used to compare the change effect of the two groups.

Description:

This study is a two-group, pre- and post-test, parallel, non-blind randomized controlled trial to test the effectiveness of the "chin retraction resistance exercise program". The convenient sampling will be used to select inpatients with stroke and dysphagia in a regional hospital from southern Taiwan. In this study, the investigators will use block randomization to assign participants to either experimental or control group, and use sealed opaque envelopes to conceal the allocation sequences. The target sample size of 80 participants will be enrolled according to sample size calculation. The CTAR exercise is to tighten a rubber ball which placed between the chin and the sternum, and to perform 3 cycles of isometric exercise and isotonic exercise. The CTAR protocol is perform CTAR exercises three times a day, five days a week, and for four weeks. The research nurses will assist in screen and recruit subjects in clinical ward units, perform the CTAR exercise protocol, and collect dates. The independent t-test will be used to compare the change effect of the two groups.

Intervention

Other:
• Chin tuck against resistance exercise
The experimental group will receive a four-week CTAR protocol and regular dysphagia care, while the control group will only receive routine dysphagia care. The routine dysphagia care is including dysphagia education, dietary precautions, oral hygiene, and swallowing training, etc. The CTAR protocol is first, the study nurses face-to-face teach dysphagia patients to perform CTAR exercises once, then the patient perform CTAR exercises three times a day, five days a week, and for four weeks. The CTAR exercise is to tighten a rubber ball which placed between the chin and the sternum, and to perform 3 cycles of isometric exercise and isotonic exercise.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The functional oral intake scale: One question, 1~7 scores.	The functional oral intake scale (FOIS) is a 7-point scale, which is used to measure the state of eating by mouth. A score of 1 means that patient can't eat by mouth at all, and a score of 7 means patient can eat food of any stickiness and type by mouth. The research nurse will use this scale to test the state of eating by mouth of participants, and collect the pre-test and four-week post-test data then record on an excel dataset.	Pre-test and four-week post-test
Primary	The penetration-aspiration scale: One question, 1~8 scores.	The penetration-aspiration scale (PAS) is an 8-point scale used to measure laryngeal leakage and aspiration severity, which with higher scores representing more severe respiratory aspiration. A score of 1 means that normal swallowing function, and a score of 8 means food mistakenly enters airway and without cough re¬flex during swallowing. The research nurse will use this scale to test the laryngeal leakage and aspiration severity of participants, and collect the pre-test and four-week post-test data then record on an excel dataset.	Pre-test and four-week post-test
Primary	The modified water swallowing test : One question, 1~5 scores.	The modified water swallowing test (MWST) is a 1 to 5-point scale, which is a routine used clinical swallowing test. The researcher nurse will inject 3ml of cold water into the bottom of the participant's mouth with an injection syringe, and then asks the participant to swallow the water for the swallowing test. If the participant is unable to swallow, or experienced dyspnea, coughing, or wet-hoarse dysphonia after swallowing, a score of 1-3 will be respective recorded. The lower the score, meaning the more serious problem of swallowing and choking. The sensitivity and specificity of MWST to differentiate between aspirators and non-aspirators with a cutoff level of 3 are 70 and 88%, respectively. The research nurse will use this scale to test the water swallowing function of participants for a screen scale of inclusion criteria, and collect the pre-test and four-week post-test data then record on an excel dataset.	Pre-test and four-week post-test
Primary	video fluoroscopic swallowing study (VFSS)	The video fluoroscopic swallowing study (VFSS) is a routine clinical swallowing photography examination to diagnosis the dysphagia problems and severity, which is perform and report by radiologist. The radiologist will interpret the image and report the swallowing function of VFSS as normal, penetration, or aspiration. The research nurse will collect the data of swallowing function on the existing VFSS reports of the electronic medical records. The collected measurement data will be aggregated on an excel dataset.photography examination, and the research nurse will collect the existing VFSS report on the electronic medical records.	Pre-test and four-week post-test
Secondary	The swallowing improvement rate: Number of participants with swallowing improvement event as assessed by the modified water swallowing test.	Based on the pre- and post-test scores of the modified water drinking test, the researcher will calculate the number of participants who have present improved at post-test scores, and then calculate the swallowing improvement rates of the two groups. The formula is: The swallowing improvement rate= Number of participants with improve events (modified water swallowing test showed the post-test score is improve compare to pre-test) ÷ number of participants of each group × 100%.	Four-week post-test
