Purpose: Patients with Parkinson's disease suffer many restrictions in daily life. This case report investigated how intervention with proprioceptive neuromuscular facilitation (PNF)-based physical therapy can affect the activities of Parkinson's patients. Methods: The subject was a 67-year-old female patient diagnosed with Parkinson's disease 3 years ago. Since the last five months, overall activities have become difficult for her, and she finally visited a hospital to take outpatient physical therapy because of the gait difficulties she suffered. The patient's medical history, system review, body structure and function, and activities were evaluated. The patient had difficulties in activities such as lying down, sitting, standing, maintaining a standing position, and walking. The PNF-based intervention was used for treating the impairments and improving the activities. The intervention was performed for 30 min a day, three times a week, for eight weeks. The qualifier of the international classification of functioning, disability, and health was used to measure the result, and the measurement was conducted before and after the intervention for eight weeks. Results: According to the result, the scores for maintaining a standing position, moving around within the home, and going to the toilet improved to "no problem" from "moderate problem." The scores for shifting the body's center of gravity, walking short distances, and washing oneself improved from "moderate problem" to "mild problem." The scores for sitting and standing improved to "no problem" and "mild problem" from "complete problem." The scores for preparing meals and doing housework improved from "severe problems" to "mild problem" or "moderate problem." The scores for walking long distances, moving around outside the home and other buildings, and using transportation did not show significant changes. Conclusion: Intervention with PNF-based physical therapy improved the activity of patients with Parkinson's disease, thus proving its effectiveness. The case report suggested that a therapist can use PNF as a physical therapy intervention for patients with Parkinson's who suffered restrictions in daily activities.

Purpose: This study examined whether the quality of life of parents of children with cerebral palsy is affected by the functions, activities, participation, and environmental factors using an ICF-CY check list. Methods: This study recruited in 26 parents of children with cerebral palsy. The functions, activities, participation, and environmental factors of the children were evaluated using ICF-CY checklist. To measure the quality of life of parents, this study used world health organization quality of life (WHOQOL-BREF), which was composed of a total of 26 questions. The GMFCS (gross motor function classification system) was used to assess the degree of disability in the children. Multiple regression analysis was performed to examine the effects of the ICF-CY checklist on the quality of life. Correlation analysis was performed to examine the correlation between GMFCS and WHOQOL. Results: The functions, activities, participation, and environmental factors were significantly different from WHOQOL-BREF. On the other hand, the contextual factor showed a significant difference in the neuromusculoskeletal and movement-related functions (b7), and service, systems, and policies (e5)(p<0.05). Conclusion: This study suggests that the functions and environmental factors affect the quality of life of parents of children with cerebral palsy. Therefore, these findings suggest that contextual factors, such as neuromusculoskeletal and movement-related functions (b7), and service, systems and policies (e5), which can be facilitators, should be considered for improving the quality of life of parents of children with cerebral palsy.

Purpose: In previous study, the frequency of osteoarthritis and discomfort were high in ankle fracture-dislocation but detail results about ankle fracture-dislocation has rarely been investigated. In this study, we retrospectively analyze the outcome of the operative treatment of ankle fracture with dislocation for over-2 years follow up. Materials and Methods: There were 47 cases of ankle fracture-dislocation in our hospital from March 2007 to May 2010. We investigated 20 patients who underwent operation and were possible for over-2 years follow up. The result was estimated with the direction of dislocation, fracture type, the time of bone union and post-traumatic osteoarthritis with plain radiologic images. In clinical assessment, we statistically evaluated the function and pain through AOFAS score and Olerud & Molander scoring system. Results: By Lauge-Hansen classification, there were 13 cases(65%) of pronation-external rotation and 6 cases(30%) of supination-external rotation, 1 case(5%) of supination-adduction. AOFAS score was 85.5, and Olerud & Molander score was "excellent" in 8 cases, "good" in 5 cases, "fair" in 3 cases and "poor" in 4 cases. Postoperative complications in 4 cases revealed post-traumatic arthritis. All kinds of lateral dislocation of ankle fracture was 15 cases and the most common. Of these, all 3 cases, anterolateral dislocation showed post-traumatic osteoarthritis. Conclusion: In ankle fracture-dislocation, post-traumatic osteoarthritis occurred in 4 of 20 patient(20%). Especially, the possibility of post-traumatic osteoarthritis was more in cases of anterolateral or lateral dislocation. So, it must be needed that deliberate examination, for example, preoperative MRI and sufficient explanation to patient. Also, we have to follow up the patients carefully.

This study evaluated the respiratory capacity of spastic cerebral palsy children who were grouped by GMFCS (Gross Motor Function Classification System) levels and identified the acoustic characteristics of three different types of Korean stops (stop consonants) which are needed for the temporal coordination of larynx and supra-larynx, in these children. Thirty-two children with dysarthria due to spastic cerebral palsy were divided into two subgroups: 14 children classified at GMFCS levels I~III were placed in Group 1 and 18 classified at GMFCS levels IV~V were placed in Group 11, and 18 children with normal speech were selected and placed in the control group. /a/ pronged phonation (sustained vowel /a/) and nine Korean VCV syllables were used. Examined acoustic characteristics were maximum phonation time (MPT) and closure duration and aspiration duration. The results were as follows: 1) The MPTs of the cerebral palsy (CP) groups, both Group I and Group II, were significantly shorter than those of the normal group. 2) The closure durations of the two CP groups were longer than those of the normal group for all 9 target syllables. 3) The aspiration durations of the two CP groups were longer than those of the normal group. 4) The closure duration of the normal and CP Group I was significantly different among tense, aspirated, and lax. However, the CP Group II was different from normal. 5) The aspiration duration of the normal and CP Group I was significantly different among aspirated, tense, and lax. However, the CP Group II was different from normal. 6) The place of articulation influenced less than the manner of articulation on closure and aspiration duration.

According to the classification of dental arch form and the analysis of patterns of chewing movement, the patterns of chewing movement in each group were evaluated and compared with those of the normal group. Results were summarized as follows ; 1. Opening phase in chewing movement In the group which the maxillary second molar positionsbuccal side, the chewing patterns which have the Vertical Guide Openings in frontal plane, the Posterior Guide Openings in hjorizontal plane were observed. In the group which the maxillary premolars position lingual side, the chewing paterns which have the Protrusive Shift Openings in horizontal plane and sagittal plane were observed. 2. Closing phase in chewing movement. In each group except for the normal group, the chewing patterns which have the Concave Closure in frontal plane and in Horizontal plane were observed. In the group which the maxillary premolars position buccal side, the chewing patterns which have the Lateral Guide Closure in frontal plane and in horizontal plane, the Vertical Guide Closre in sagittal plane were observed: From the results, as the characteristics of the dental arch form have appeared in chewing movement, the close relationships were found between dental arch form and chewing movement. It is suggested that the evaluation of dental arch form is effective in the diagnosis of function of stomatognathic system.

Although limited progress have been made about pathogen system of Hibiscus rosa-sinensis and Hibiscus latent Fort Pierce virus (HLFPV), interaction between plant host and pathogen remain largely unknown, which led to deficiency of effective measures to control disease of hibiscus plants caused by HLFPV. In this study, infection of HLFPV in Hibiscus rosa-sinensis was firstly confirmed for the first time by traditional electron microscopy, modern reverse transcription polymerase chain reaction and RNA-seq methods in China (HLFPV-Ch). Sequence properties analyzing suggested that the full-length sequences (6,465 nt) of HLFPV-Ch had a high sequence identity and a similar genomic structure with other tobamoviruses. It includes a 5'-terminal untranslated region (UTR), followed by four open reading frames encoding for a 128.5-kDa replicase, a 186.5-kDa polymerase, a 31-kDa movement protein, 17.6-kDa coat protein, and the last a 3'-terminal UTR. Furthermore, HLFPV-Ch-derived virus-derived siRNAs (vsiRNAs) ant its putative target genes, reported also for the first time, were identified and characterized from disease Hibiscus rosa-sinensis through sRNA-seq and Patmatch server to investigate the interaction in this pathogen systems. HLFPV-Ch-derived vsiRNAs demonstrated several general and specific characteristics. Gene Ontology classification revealed predicted target genes by vsiRNAs are involved in abroad range of cellular component, molecular function and biological processes. Taken together, for first time, our results certified the HLFPV infection in China and provide an insight into interaction between HLFPV and Hibiscus rosa-sinensis.
