[Purpose] The purpose of this study was to investigate the effect of treatment on the type of taping applied before proprioceptive neuromuscular facilitation treatment. [Subjects and Methods] This study was conducted on thirty patients diagnosed with stroke. The study subjects were divided into three groups: experimental group 1, experimental group 2, and control group 3. Experimental group 1 applied Kinesio taping to the lower limb before applying proprioceptive neuromuscular facilitation technique. Experimental group 2 applied McConnell taping to the lower limb before applying proprioceptive neuromuscular facilitation technique and control group applied only proprioceptive neuromuscular facilitation technique. In this study was used Dartfish to analyze the gait of the lower limbs. [Results] Experiment group 1 showed a significant difference of ankle angle compared to the control group, but a statistically significant difference of ankle angle was observed in week 8. Experiment group 1 and experiment group 2 showed a significantly longer stride length on the affected side than the control group. [Conclusion] Application of Kinesio taping has a more positive effect on the ambulation than McConnell taping. © 2017 The Society of Physical Therapy Science.

This paper deals with the security problems facing with next generation computing environments. As the method, Virtualized Security Defense System (VSDS) is proposed under the application of 'Trello'(web application) for online patient networks, it deals with the following problems; (1) blurred security boundaries between attackers and protectors, (2) group key management system, (3) secret-collaborative works and sensitive information-sharing for group members, (4) preserving privacy, (5) rendering of 3D image(member indicator, high level of security). Consequently, although current IT paradigm is changing to more 'complicated', 'overlapped' and 'virtualized', VSDS makes it securely possible to share information through collaborative works. © 2016 The authors and IOS Press.

[Purpose] The purpose of this study was to investigate the impact on rat knee joints of extracorporeal shock wave therapy after experimentally induced intracerebral hemorrhage. [Subjects and Methods] Sprague-Dawley (SD) rats were divided into an experimental group that received extracorporeal shock wave therapy after central nervous system injury (n=10) and a control group that did not receive any therapeutic intervention after central nervous system injury (n=10). The Dartfish program was used to evaluate the SD rats’ locomotion. [Results] There was a significant difference between the control group and the experimental group in the change of knee joint angle during midstance after the intervention. [Conclusion] In conclusion, at extracorporeal shock wave therapy for central nervous system injury was confirmed to be effective at reducing knee joint angle, confirming it is a good physical therapy intervention, based on its efficacy. © 2016 The Society of Physical Therapy Science.


[Purpose] The current study attempted to examine the effects of centrifugal contraction exercise of the rectus abdominis during the isometric contraction of the transversus abdominis on pain and balance of patients with chronic back pain. [Subjects and Methods] The subjects included thirty patients who were diagnosed with back pain due to causes other than neurological by a specialist after conducting a medical precision diagnosis. The experiment was performed after evenly dividing the subjects into two groups, namely, control and experimental, using a random method. This study measured pain by using the visual analog scale. To determine the patients’ balancing ability using the Multifunktionale trainsgerate balance measurer. [Results] All groups showed a statistically significant within-group difference in visual analog scale and balance change. However, no significant between-group difference was observed in the comparison of therapy effects. [Conclusion] Strengthening the rectus abdominis can be an important factor for increasing the stability and reducing the pain of the lumbar area among patients with back pain. © 2017 The Society of Physical Therapy Science.

We would like to establish the intrinsic structure and properties of Laplace-typed integral transforms. The methodology of this article is done by a consideration with respect to the common structure of kernels of Laplace-typed integral transform, and G-transform, the generalized Laplace-typed integral transform, is proposed with the feature of inclusiveness. The proposed G-transform can provide an adequate transform in a number of engineering problems. © 2017 Hwajoon Kim.

Background We sought to find the therapeutic effect of 5Hz high-frequency repetitive transcranial magnetic stimulation (rTMS) over the unaffected pharyngeal motor cortex in post-stroke dysphagic patients. Methods Eighteen patients with unilateral hemispheric stroke oropharyngeal dysphagia that lasted more than 1month were randomly divided into two groups. They all performed videofluoroscopic swallowing study (VFSS) before rTMS intervention. The experimental group (EG) received 5Hz rTMS over contra-lesional pharyngeal motor cortex for 10min per day for 2weeks. The control group (CG) received sham stimulation under the same condition. Videofluoroscopic swallowing study were performed again just after treatment cessation and 2 weeks afterward. The evaluation was performed using videofluoroscopic dysphagia scale (VDS) and penetration-aspiration scale (PAS). Key Results Mean baseline VDS and PAS of EG was 33.6±12.1 and 3.41±2.32 respectively and the scores were reduced to 25.3±9.8 and 1.93±1.52 just after 2weeks intervention (P<0.05). This effect lasted for up to 2 weeks after treatment. However, there was no change in the CG. Baseline prevalence of aspiration, pharyngeal residue, delayed triggering of pharyngeal swallowing and abnormal pharyngeal transit time (PTT) in EG was 66.7%, 66.7%, 33.3%, and 44.4%, respectively. After rTMS, the prevalence of aspiration and pharyngeal residue was reduced to 33.3% and 33.3%, respectively. However, the prevalence of delayed triggering and abnormal PTT was not changed. Conclusions & Inferences A 5Hz high-frequency rTMS on contra-lesional pharyngeal motor cortex might be beneficial for post-stroke dysphagic patients. This intervention can be used as a new treatment method in post-stroke patients with dysphagia. © 2012 Blackwell Publishing Ltd.

We tested the effect of effortful swallow combined with surface electrical stimulation used as a form of resistance training in post-stroke patients with dysphagia. Twenty post-stroke dysphagic patients were randomly divided into two groups: those who underwent effortful swallow with infrahyoid motor electrical stimulation (experimental group, n = 10) and effortful swallow with infrahyoid sensory electrical stimulation (control group, n = 10). In the experimental group, electrical stimulation was applied to the skin above the infrahyoid muscle with the current was adjusted until muscle contraction occurred and the hyoid bone was depressed. In the control group, the stimulation intensity was applied just above the sensory threshold. The patients in both groups were then asked to swallow effortfully in order to elevate their hyolaryngeal complex when the stimulation began. A total of 12 sessions of 20 min of training for 4 weeks were performed. Blinded biomechanical measurements of the extent of hyolaryngeal excursion, the maximal width of the upper esophageal sphincter (UES) opening, and the penetration-aspiration scale before and after training were performed. In the experimental group, the maximal vertical displacement of the larynx was increased significantly after the intervention (p < 0.05). The maximal vertical displacement of the hyoid bone and the maximal width of the UES opening increased but the increase was not found to be significant (p = 0.066). There was no increase in the control group. Effortful swallow training combined with electrical stimulation increased the extent of laryngeal excursion. This intervention can be used as a new treatment method in post-stroke patients with dysphagia. © 2012 Springer Science+Business Media, LLC.

This study investigated the caring effect of hand massage using aroma essential oil and music therapy on an anxiety and sleeping for the 72 elderly comprising of groups I (24 elderly) and II (25) and a control group (23) living in the sanatorium. The group I was given with hand massage using aroma essential oil and music therapy at the same time twice a week, for 4 weeks, while group II was with only hand massage using aroma essential oil and the control group was with none. Despite no difference between beforehand between group I and II, the average anxiety scores (AAS) of the group I has statistically significantly reduced; AAS of the group I has reduced by 4 from beforehand 53 to afterward 49, while group II by 1 from 52 to 51. However, there was no significant difference in improvement in sleeping among groups. This study demonstrates that non-medicated, hand massage using aroma essential oil coupled with music therapy can be effective for relieving the anxiety of the elderly living in the sanatorium. © 2015 SERSC.

Objective: The diagnosis of central paroxysmal positional nystagmus (CPPN) is challenging, and the mechanisms require further elucidation. This study aimed to determine the characteristics and mechanisms of CPPN. Methods: Seventeen patients with CPPN were subjected to analyses of their clinical findings, MRI lesions, and oculographic data on spontaneous and positional nystagmus. Results: The direction of CPPN was mostly aligned with that of the head motion during the positioning, and 3 types of CPPN were identified: downbeat nystagmus on straight-head hanging, upbeat nystagmus on uprighting, and apogeotropic nystagmus during supine head roll test. The direction of CPPN was aligned with the vector sum of the rotational axes of the semicircular canals that were normally inhibited during the positioning. The intensity of evoked nystagmus was at its peak initially and then decreased exponentially over time. The time constants (TC) of the vertical CPPN ranged from 3 to 8 seconds, which corresponds to the TC of the vertical rotational vestibulo-ocular reflex. Sixteen patients (94.1%) showed more than one type of CPPN. Furthermore, persistent downbeat or apogeotropic positional nystagmus was associated in 11 patients (64.7%). Most patients with CPPN from a circumscribed brain lesion showed an involvement of the cerebellar nodulus or uvula. Conclusion: CPPN may be ascribed to enhanced responses of the vestibular afferents due to lesions involving the nodulus and uvula. CPPN could be differentiated from benign paroxysmal positional nystagmus by positional nystagmus induced in multiple planes, temporal patterns of nystagmus intensity, and associated neurologic findings suggestive of central pathologies. © 2015 American Academy of Neurology.
