Tongue pressure strength and accuracy training (TPSAT) has been proposed as an intervention to improve dysphagia. However, the effects of TPSAT on dysphagia in subacute stroke patients remain unclear. The aim of this study was to investigate the effects of TPSAT on tongue pressure strength, swallowing function, and quality of life in subacute stroke patients with dysphagia. Sixteen subacute stroke patients were assigned randomly to two groups: the TPSAT group (n=8) or the control group (n=8). In the former, both TPSAT and traditional dysphagia therapies were performed for 30 min each per day; in the latter, only traditional dysphagia therapy was performed for 30 min twice a day. Both groups performed each daily intervention five times per week for 8 weeks. To assess the tongue pressure strength, maximum isometric tongue pressures (MIPs) of the anterior and posterior tongue using the Iowa Oral Performance Instrument were measured before and after the intervention. Mann Assessment of Swallowing Ability (MASA) and Swallowing-Quality of Life (SWAL-QOL) were also used to assess the swallowing function and quality of life, respectively. TPSAT with traditional dysphagia therapy significantly improved MASA, SWAL-QOL, and MIPs both anteriorly and posteriorly, and traditional dysphagia therapy significantly increased MASA, SWAL-QOL, and MIPs anteriorly (P<0.05). The TPSAT group showed a significant improvement in anterior and posterior MIPs and tongue movement score in MASA compared with the control group (P<0.05). Our findings suggest that TPSAT may significantly improve dysphagia management in subacute stroke patients.

[Purpose] This study was conducted to identify the effects of expiratory muscle strength training on swallowing function in acute stroke patients with dysphagia. [Subjects and Methods] A total of 18 stroke patients with dysphagia were enrolled in the study. All participants were randomly assigned to either an experimental group (n=9) or a control group (n=9). All participants performed traditional-swallowing rehabilitation therapy in 30-minute sessions five times a week for four weeks; however, only the experimental group received expiratory muscle strength training. [Results] Both groups showed significant improvements after mediation. When compared with the control group, the functional dysphagia scale, vallecular residue, and penetration-aspiration scale were significantly improved in the experimental group. [Conclusion] Expiratory muscle strength training is an effective intervention for impaired swallowing function in acute strike patients with dysphagia.

[Purpose] The purpose of this study was to analyze the effect of Graston Technique on hamstring extensibility and pain intensity in patients with nonspecific low back pain. [Subjects and Methods] Twenty-four patients with nonspecific low back pain (27–46 years of age) enrolled in the study. All participants were randomly assigned to one of two groups: Graston technique group (n=12) and a static stretching group (n=12). The Graston Technique was used on the hamstring muscles of the experimental group, while the static stretching group performed static stretching. Hamstring extensibility was recorded using the sit and reach test, and a visual analog scale was used to measure pain intensity. [Results] Both groups showed a significant improvement after intervention. In comparison to the static stretching group, the Graston technique group had significantly more improvement in hamstring extensibility. [Conclusion] The Graston Technique is a simple and effective intervention in nonspecific low back pain patients to improve hamstring extensibility and lower pain intensity, and it would be beneficial in clinical practice.

[Purpose] This study investigated the effects of lingual strength training (LST) on lingual strength and articulator function in stroke patients with dysarthria. [Subjects and Methods] 16 stroke patients with dysarthria were randomly assigned into two groups: the experimental group (n=8) or the control group (n=8). Both groups received the conventional rehabilitation therapy at 30 min/day, 5 times for week, and during 4 weeks, and the experimental group received an additional 30 min of LST using the Iowa Oral Performance Instrument (IOPI). The Maximum Isometric Tongue Pressures (MIPs) was used to assess the lingual strength and the Alternating-Motion Rate (AMR) and Sequential-Motion Rate (SMR) were used to measure the articulator function. [Results] After the intervention, the experimental group showed a significant improvement in MIPs and AMR (/tə/) than the control group. [Conclusion] Findings of this study suggest that LST provides positive effects on lingual strength and articulator function, and thus can be used as an interventional method in stroke patients with dysarthria.

Abstract.[Purpose] The aim of this study was to examine the effects of the manual facilitation technique (MFT) on swallowing and prevention of aspiration pneumonia in patients with severe dysphagia following stroke, who receive tube feeding because of their inability to respond to verbal commands.[Subjects] The subjects were three patients diagnosed with quadriplegia and severe dysphagia as well as a history of aspiration pneumonia. [Methods] MFT to the larynx after oral sensory treatment was performed for 20 minutes, daily, for the two weeks. For MFT to the larynx, the Mendelsohn maneuver after deep sense stimulation of the larynx was performed. To find out the effect of the MFT, saliva swallowing frequency and the development of aspiration pneumonia were recorded.[Results] None of the subjects were able to perform saliva swallowing before the treatment, but all were able to during the treatment. Also, saliva swallowing frequency was increased in the treatment period (Subject 1: 3.79 times on average, Subject 2: 4.93 on average, Subject 3: 5.71 times on average).[Conclusion] Our results show that MFT to the larynx after oral sensory treatment improved the function of saliva swallowing and had a positive effect on preventing aspiration pneumonia relapse in severe dysphagia patients with inability to respond to verbal commands.
