To demonstrate the usefulness of early videofluoroscopic swallowing study (VFSS) and to investigate change patterns in dietary methods in stroke patients with dysphagia.
The VFSS was performed within 7 days of stroke onset in neurologically stable patients. The patients were divided into three groups according to type of brain lesion: cortical lesion (CL), subcortical lesion (SCL), and brainstem/cerebellar lesion (BCL). Based on the VFSS results, this study investigated change patterns in feeding method and discrepancies in the aspiration risk predicted by the Water Swallowing Test (WST) and the VFSS. Complications, such as aspiration pneumonia, were also evaluated.
A total of 163 patients met the inclusion criteria and the VFSS was performed within 7 days of stroke. Patients considered at risk for aspiration (Penetration-Aspiration Scale [PAS] scores of 6 to 8) were found in all three groups using the VFSS (47.5% of the CL group, 59.3% of the SCL group, and 47.9% of the BCL group). After early VFSS, 79.7% of the patients were assessed to require restricted feeding methods. A 19.0% discrepancy was found between the WST and VFSS results. At 3-week follow-up after the VFSS, aspiration pneumonia was observed in 12 patients (7.4%) with restricted feeding methods.
Early VFSS during the acute period can facilitate determination of the most appropriate feeding method, and support effective dysphagia management for stroke patients.

To evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke.
Twenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a day with or without mirror therapy for 30 minutes a day were performed under supervision. All groups received conventional occupational therapy for 40 minutes a day for the same period. The CIMT only group and control group also received additional self-exercise to substitute for mirror therapy. The box and block test, 9-hole Pegboard test, grip strength, Brunnstrom stage, Wolf motor function test, Fugl-Meyer assessment, and the Korean version of Modified Barthel Index were performed prior to and two weeks after the treatment.
After two weeks of treatment, the CIMT groups with and without mirror therapy showed higher improvement (p<0.05) than the control group, in most of functional assessments for hemiplegic upper extremity. The CIMT combined with mirror therapy group showed higher improvement than CIMT only group in box and block test, 9-hole Pegboard test, and grip strength, which represent fine motor functions of the upper extremity.
The short-term CIMT combined with mirror therapy group showed more improvement compared to CIMT only group and control group, in the fine motor functions of hemiplegic upper extremity for the patients with subacute stroke.

To compare the outcome of an early application of neuromuscular electrical stimulation (NMES) combined with traditional dysphagia therapy (TDT) versus traditional dysphagia therapy only in acute/subacute ischemic stroke patients with moderate to severe dysphagia by videofluoroscopic swallowing study (VFSS).
Fifty-seven dysphagic stroke patients were enrolled in a VFSS within 10 days after stroke onset. Patients were randomly assigned into two treatment groups. Thirty-one patients received NMES combined with TDT (NMES/TDT group) and 26 patients received TDT only (TDT group). Electrical stimulation with a maximal tolerable intensity was applied on both suprahyoid muscles for 30 minutes, 5 days per week during 3 weeks. The swallowing function was evaluated at baseline and 3, 6, and 12 weeks after baseline. Outcomes of the VFSS were assessed using the Functional Oral Intake Scale (FOIS).
The mean ages were 63.5±11.4 years in the NMES/TDT group and 66.7±9.5 years in the TDT group. Both groups showed a significant improvement on the FOIS after treatment. The FOIS score was significantly more improved at 3 and 6 weeks after baseline in the NMES/TDT group than in the TDT group (p<0.05).
An early application of NMES combined with TDT showed a positive effect in acute/subacute ischemic stroke patients with dysphagia. These results indicated that the early application of NMES could be used as a supplementary treatment of TDT to help rehabilitate acute/subacute dysphagic stroke patients by improving their swallowing coordination.

Effectiveness of Neuromuscular Electrical Stimulation on Post-Stroke Dysphagia: A Systematic Review of Randomized Controlled Trials
To evaluate the effect of prolonged inpatient rehabilitation therapy in subacute stroke patients.
We enrolled 52 subacute stroke patients who had received 3 months of inpatient rehabilitation therapy. Thirty stroke patients received additional inpatient rehabilitation therapy for 3 months and 22 control patients received only home-based care. The evaluation was measured at 3 and at 6 months after stroke occurrence. Functional improvement was measured using the modified motor assessment scale (MMAS), the timed up and go test (TUG), the 10-meter walking time (10 mWT), the Berg balance scale (BBS) and the Korean-modified Barthel index (K-MBI). The health-related quality of life was evaluated using the medical outcome study, 36-item short form survey (SF-36).
In the experimental group, significant improvements were observed for all parameters at 6 months (p<0.05). However, significant improvements were observed only in MMAS, BBS, and K-MBI at 6 months in the Control group (p<0.05). In comparing the 2 groups, significant difference were observed in all parameters (p<0.05) except 10 meter walking time (p=0.73). The improvement in SF-36 was meaningfully higher in experimental group compared to control group.
This study demonstrates that subacute stroke patients can achieve functional improvements and an enhanced quality of life through prolonged inpatient rehabilitation therapy.

Objective: The aim of this study was to evaluate the clinical usefulness of motor evoked potentials (MEPs) in predicting functional motor recovery of acute stroke patients.
Method: Nineteen acute stroke patients were assessed clinically by manual muscle test (MMT) & modified Barthel index (MBI) and SEP & MEP at about 10 days after stroke. Follow up clinical assessments were performed by MMT, MBI & gait evaluation after two months of rehabilitation program.
Results: 1) In the acute phase of stroke, there was a significant relationship between MEP and motor function. 2) The presence of MEPs in hemiparetic upper & lower extremities was correlated with better functional outcome than the absence of MEP in at least one extremity. MEP was better than SEP in predicting functional outcome following acute stroke. 3) The presence of MEP in hemiparetic abductor pollicis brevis muscle was correlated with a better functional improvement, contrarily the absence of MEP in abductor hallucis muscle was correlated with a worse functional outcome.
Conclusion: We concluded that MEP study is a useful assessment tool in predicting functional outcome of acute stroke patient. However, the absence of MEP does not necessarily indicate a poor prognosis. So further study is needed to clarify this controversy.
