effects of chin tuck against resistance exercise on patients with dysphagia after stroke

Conditions: Stroke

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.

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.

Eligibility criteria:
inclusion criteria: * inpatients with newly diagnosed stroke with dysphagia. * the modified water swallowing test shows that ≦ 4 points, which mean patient have a high risk of swallowing disorders. * adults over 20 years old, without visual, hearing and mental disabilities. * patients who have clear consciousness and can sit up at least 10 minutes to cooperate with swallowing training. exclusion criteria: * in addition to not meeting the above selection criteria, those who have head and neck cancer or movement disorders and cannot cooperate with the chin tuck against resistance exercise will be listed as excluded cases.
