Moebius syndrome (MBS) is a congenital neurologic disorder that causes cranio-facial abnormalities. It involves paralysis of the VI and VII cranial nerves and causes bilateral or unilateral facial paralysis, eye movement disorder, and deformation of the upper and lower limbs. The orofacial dysfunctions include microstomia, micrognathia, hypotonic mimetic and lip muscles, dental enamel hypoplasia, tongue deformity, open bite or deep overbite, maxillary hypoplasia, high arched palate, mandibular hyperplasia or features indicating mandibular hypoplasia. This case report presents a 7-year-old male patient who was diagnosed with MBS at the age 2 years. The patient displayed typical clinical symptoms and was diagnosed with Class II malocclusion with a large overjet/overbite, tongue deformity and motion limitation, and lip closure incompetency. Treatment was initiated using a removable appliance for left scissor bite correction. After permanent tooth eruption, fixed appliance treatment was performed for correction of the arch width discrepancy and deep overbite. A self-ligation system and wide-width arch form wire were used during the treatment to expand the arch width. After 30 months of phase II treatment, the alignment of the dental arch and stable molar occlusion was achieved. Function and occlusion remained stable with a Class I canine and molar relationship, and a normal overjet/overbite was maintained after 9.4 years of retainer use. In MBS patients, it is important to achieve an accurate early diagnosis, and implement a multidisciplinary treatment approach and long-term retention and follow-up.

Fahr disease (FD) is a rare neurological disorder characterized by presence of abnormal and associated cell loss in certain areas of the brain, mostly in basal ganglia, thalamus, cerebellum and subcortical areas. Approximately two-thirds of the patients are symptomatic. The most common neurological manifestations include movement disorders, cognitive impairment, cerebellar signs and speech disorders. We report one case of estimated FD through brain computed tomography (bilateral calcifications of basal ganglia, thalamus, centrum semiovale, subcortical white matter of occipital lobes, cerebellum). At the first time of treatment, he complained of tremors in his upper limbs. We diagnosed the patient as deficiency of qi (氣) and movement of phlegm-heat-wind (痰熱風動) type according to symptoms and treated by herbs and acupuncture of oriental medicine. During treatments, we evaluated how well the oriental medical treatments were working using visual analogue scale (VAS) and amplitude of hands. After the oriental medical treatments about tremor, VAS dropped from 10 to 2 and amplitude of hands from 20 mm to 2 mm, but the ratio of brain calcifications was not changed. This study suggests that oriental medical treatments can be applicable to improve FD.

Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

Purpose: This study was conducted to examine the effects of a PNF intervention using elastic bands on edema, range of motion (ROM), and pain in post-mastectomy patients with upper limb lymphedema, according to their hand grip type. Methods: The subjects were 14 female patients who were at Stage II lymphedema after undergoing mastectomy for Stage II breast cancer. They were randomly divided into an experimental group (n =7) and a control group (n = 7). Both groups participated in a treatment program four times (one time under the therapist's instructions and three times as self-exercise) a week for 4 weeks. Both groups repeated an upper limb PNF pattern exercise for 30 min using elastic bands after receiving a manual lymph drainage treatment for 1 hour. Here, subjects in the experimental group performed the PNF exercise with an open-hand grip by putting their hands into the loops of elastic bands and keeping their fingers spread out. Subjects in the control group performed the PNF exercise with a closed-hand grip by holding the loops of elastic bands with their fingers. In both groups, the subjects' edema, ROM, and pain levels were measured before the intervention and 2, 3 and 4 weeks after the intervention. Results: As a result of the experiment, both groups demonstrated edema reductions, ROM increases, and pain reductions in four areas of the upper limbs. Notably, the experimental group exhibited larger ROM increases in flexion, extension, and abduction as well as greater edema and pain reductions than the control group. In particular, the most significant effects were found in the elbow of the four upper limb areas for edema reductions and in extension for ROM increases. Conclusion: The present study indicates that exercise therapy-based approaches using elastic bands in post-mastectomy patients with upper limb lymphedema can have different effects depending on the type of hand grip (open or closed), which is the body's most distal part. Therefore, these approaches should be based on the conditions of the distal parts of the patient's body for their effective applications in clinical practice.

The purpose of this study was to compare EMG and GRF during a free throw. Seven pairs of surface electrodes were attached to the right-hand side of the body to monitor the flexor carpi radialis (FC), extensor carpi radialis longus (EC), biceps brachii (BB), triceps brachii (TB), rectus femoris (RF), tibialis anterior (TA) and medial gastrocnemius (GM). GRF data from two force platform were collected during a free throw. The results showed that the muscle activities in the unskilled group must be highly activated prior to the moment of release. This means that a skilled participant can shoot a free throw more efficiently while producing less muscle activeness than an unskilled participant. The DCP of unskilled group in the medio-lateral direction were greater than the corresponding values in skilled group. This showed that the unskilled group were not able to shoot the free throws stably. Thus, when a teacher or instructor teaches students how to shoot free throw, it is considered that the teacher show the learner how to use not only the upper limbs but also lower limbs on the basis of the efficent connecting movement and the flexibility in a stable procedure.

The purpose of this research was to analyze the kinematics of the 205B movement in platform diving. For the experiment, 2 athlete from the national diving team were chosen as the subject and two S -VHS video cameras were used. For this diving players preparing for the olympics participated. It was shown that the mean total took $1.112{\pm}0.12s$. In order to perform better, the divers time must be increased, at take off and rotation must be done high up and the horizontal distance must be shorted to main entrance of the water. To enter the water safely, the jump has to be high, the horizontal speed slow and the vertical speed as fast as possible. At E1 the lower limbs change in speed should decrease and after the rotation begins at E2. At take off, the jump is more important than the rotation for the performance of the dive. At take off, the trunk angular velocity was high, and this was needed to jump high for moment of inertia for rotation because for efficient jumping the upper body has to spread out and increase the height of the center of mass.

Background: Therapeutic climbing training, which originated in Germany, is a wall-hanging rock climbing-based therapy to increase the body's coordination through movement of the upper and lower limbs against gravity. However, there are no studies examining the effectiveness of therapeutic climbing training to treat balance and gait ability in patients with chronic stroke. Objectives: To investigate therapeutic climbing training program on balance and gait in patients with chronic stroke. Design: Pretest-posttest control group design. Methods: Fourteen patients with chronic hemiplegic stroke participated. Participants were randomized into the therapeutic climbing training group (TCTG, n=7) and the standard rehabilitation program group (SRPG, n=7) group. All subjects participated in the same standard rehabilitation program consisting of 60 minutes 5 times a week for 6 weeks. TCTG participated additionally in the therapeutic climbing program consisting of 30 minutes sessions 3 times a week for the same 6 weeks. Berg balance scale (BBS), Gaitview Measure, Timed up and go test (TUG) were measured. Results: In the TCTG, revealed a statistical difference in BBS between the groups; in the difference of plantar pressure ratio in the static standing position revealed a statistical difference between the groups after training; the balance ability in the one-leg standing tests increased significantly; the time in TUG decreased significantly after training in both groups; The changes in the difference of dynamic plantar pressure ratio were reduced significantly in the TCTG. Conclusion: Therapeutic climbing training contribute to improve balance and walking function in patients with chronic stroke.

Objective: Cerebral palsy (CP) is a neurodevelopment disorder attributed to an insult or injury to the developing brain with abnormalities in muscular tone, movement and motor skill. Improvement in quality of life and ameliorating symptoms can be achieved. Therefore, this case report details a distinctive approach to treating a 5-year-old male child with quadriplegic spastic cerebral palsy utilizing Unani treatment modalities. Methods: The treatment regimen commenced with 'Habb Ayarij for constipation followed by Sharbat Ustukhuddus administered orally. Notably, Sharbat Ustukhuddus was combined with Melia Azedarach L. leaves vapour bath. Subsequently, Roghan Babunna douche was performed followed by Dalk Layyin andcontinued until symptomatic improvement was observed. Majun Falasfa, Khamira Marwareed and Khameera Gauzaban were administered for 30 days. The therapeutic outcome included anthropometrical measurements, developmental milestones, spasm/reflex scale, and muscle power grading. Results and conclusion: Over the course of a 2-year follow-up, several clinical findings emerged. These included notable improvements in anthropometric measurements, developmental milestones such as improved head control and sitting ability, and a reduction in spasticity of the upper limbs, along with decreased muscle spasms. The therapeutic outcome of this individualized and holistic approach is potentially due to the multifaceted properties of medicinal plants (Musakkin wa Muharrik wa Muqawwi-i- A'sab wa Dimāgh, Munawwim, Dafi-i-Tashannuj, Muqawwi-i-Qalb-i-Ruh). Furthermore, the use of Dalk and Naṭūl was instrumental in providing nourishment to musculoskeletal cells and initiating intracellular signaling cascades. While these findings are encouraging, further research in the form of case series andrandomized controlled trials is warranted to validate the efficacy of this unique holistic approach.

Objective: This study aimed to investigate how the movements occurring during the follow-through phase after releasing an arrow among elite compound archers, are associated with the arrow impact points on the target. Method: Nine elite archers performed consecutive compound archery shooting under conditions identical to actual competitions using their own bows and equipment. Motion capture system and force platform were utilized to record the changes in joint positions and center of pressure, respectively. Principal component analysis was employed to identify the patterns in which multidimensional joint positions and COP changes were organized with horizontal and vertical coordinates of arrow impact points. Subsequently, correlation analysis quantified the relationship between individual variables and the coordinates of arrow impacts on the target. Results: We found a common organizational pattern in which the two axes of the impact point coordinates were grouped into the first two principal components. The movements of the upper and lower limbs following release exhibited opposite patterns in the anterior-posterior axis, with significant correlations observed between the arrow impact points of the horizontal axis and the left shoulder, right elbow, left hip, and both knees. Additionally, the lateral movements induced by the reaction force upon arrow release showed significant associations with the vertical coordinates of the impact points. Particularly, the correlations between the movements of the left shoulder and elbow, as well as the bilateral hip and right knee, were consistently observed among all participants. Conclusion: These findings implied that the post-release movements could significantly influence the trajectory and impact points of the arrows in compound archery. We suggest that a consistent and controlled movement during the follow-through phase may be more beneficial for optimizing shooting accuracy and precision rather than minimizing movements.

This paper aims at developing 'gyro-mouse' which provides decent and comfortable human-computer interface that supports the usage of such software as an internet-browser in PC for the people paralyzed in upper limbs. This interface operates on information collected from head movement to get the cursor control. The interface is composed of two modules. One is hardware module in which the head horizontal and vertical angular velocities are detected and transmitted into PC. The other is a PC software that translates the received data into movement and click signals of the mouse. The ANN (artificial neural network) learns the quick nodding pattern of each user as click input so that it can provide user-friendly interface. The performance of the system was evaluated by three indices that are click recognition rate. error in cursor position control. and click rate of the moving target box. The performance result of the gyro-mouse was compared with that of the optical-mouse to assess the efficiency of the gyro-mouse. The average click recognition rate was 93%, average error in cursor position control was 1.4∼5 times of optical mouse. and the click rate with 50 pixels target box was 40%(30 clicks/min) to that of optical mouse. The click rate increased monotonously with the number of trial from 35% to 44%. The suggested system is expected to provide a new possibility to communicate with the society.
