[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.
The purpose of this study is to evaluate the effect of three-dimensional preformed titanium membrane (3D-PFTM) to enhance mechanical properties and ability of bone regeneration on the peri-implant bone defect. 3D-PFTMs by new mechanically compressive molding technology and manually shaped- (MS-) PFTMs by hand manipulation were applied in artificial peri-implant bone defect model for static compressive load test and cyclic fatigue load test. In 12 implants installed in the mandibular of three beagle dogs, six 3D-PFTMs, and six collagen membranes (CM) randomly were applied to 2.5 mm peri-implant buccal bone defect with particulate bone graft materials for guided bone regeneration (GBR). The 3D-PFTM group showed about 7.4 times higher mechanical stiffness and 5 times higher fatigue resistance than the MS-PFTM group. The levels of the new bone area (NBA, %), the bone-to-implant contact (BIC, %), distance from the new bone to the old bone (NB-OB, %), and distance from the osseointegration to the old bone (OI-OB, %) were significantly higher in the 3D-PFTM group than the CM group (p < .001). It was verified that the 3D-PFTM increased mechanical properties which were effective in supporting the space maintenance ability and stabilizing the particulate bone grafts, which led to highly efficient bone regeneration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
