The present study was designed to develop the functional electrical stimulation system in order to restore motor function of paralytic patients. We attempt to establish adequate stimulus parameters for the recovery of work unction in lower limb paralysis patients and to develop the electrical stimulation system, which is effective to protect foot drop in these patients. In our animal and human experiment, adequate stimulus condition for surface electrode on the lower limb were 0.2-0.3ms at the duration and 50 Hz, which contain 600Hz train pulse. This parameter has efficiently prevented the foot drop from lower limb paralysis, decreased muscle fatigue and induced powerful contraction of lower limb muscle.

Facial nerve palsy has an effect on a person's well-being functionally and psychologically. Therefore, comprehensive patient management is essential. One of the most common uncomfortable and potentially debilitating features is associated with the incapacity for eye closure. Restoration of eye closure is a key consideration during the surgical management of facial palsy. In this article, we introduce simple surgical methods-which are relatively easy to learn and involve the upper and lower eyelids-for achieving eye closure. Correcting upper eyelid function involves facilitating the component of eye closure that is in the same direction as gravity and is, therefore, less complicated and favorable outcomes than correction of lower lid. Aesthetic aspects should be considered to correct the asymmetry caused by facial palsy. Lower eyelid function involves a force that opposes gravity for eye closure, which makes correction of lower eyelid ectropion more challenging than surgery for the upper eyelid, particularly in terms of effecting a sustained correction. Initially, proper ophthalmic evaluation is required, including identifying the chronicity and severity of ectropion. Also, it is important to determine whether or not lateral canthoplasty is necessary. The lateral tarsal strip procedure is commonly used for lower lid correction. However, effective lower lid correction can be achieved with better cosmesis when extensive supporting techniques are applied, including those involving cheek tissue.

Facial palsy (FP) is a functional disorder of the facial nerve involving paralysis of the mimic muscles. According to the principle "time is muscle," early surgical treatment is tremendously important for preserving the mimic musculature if there are no signs of nerve function recovery. In a 49-year-old female patient, even 19 months after onset of FP, successful neurotization was still possible by a V-to-VII nerve transfer and cross-face nerve grafting. Our patient suffered from complete FP after vestibular schwannoma surgery. With continuous application of electrostimulation (ES) therapy, the patient was able to bridge the period between the first onset of FP and neurotization surgery. The significance of ES for mimic musculature preservation in FP patients has not yet been fully clarified. More attention should be paid to this form of therapy in order to preserve the facial musculature, and its benefits should be evaluated in further prospective clinical studies.

This study is intended to investigate if the standard of vocational rehabilitation service could be solely determined by medical standard for disability definement and to find out what alternatives are available to resolve practical problems for those who are not identified as the severely disabled by the disability definement but do experience severe handicaps at work. Through the literature review, the researcher argued that the concept of 'functional limitation' would be a criteria, and thereby applied Modified Barthel Index to measure the degree of functional limitation. In view of researching the relationship among physical impairment, functional limitation, and job status based on 381 cerebral palsied, variables such as the type of cerebral palsy and the part of paralysis, have neither direct nor indirect influence to the job status; however, the pain and the mobility have indirect effects, and the ability of self-management has direct effect on the job status. The researcher concluded that future research about disabilities needs to provide a serious thought on what it is to be defined as 'disabilities', as well as to focus on further research conceptualizing the degree of physical 'functional limitation'.

Vocal cord paralysis (VCP) is a common complication after thyroidectomy despite the continuity of the recurrent laryngeal nerve (RLN) is preserved. Much efforts have been made into preventing VCP, but few of them focuses on the treatment strategies and prognosis after VCP take place. In this case, patient visited the clinic for papillary thyroid cancer in Rt. thyroid gland without VCP. She underwent total thyroidectomy with central neck dissection. During dissection, Rt main mass was encircling Rt. RLN. To make matters worse, Lt. RLN was severed due to tight attachment with Berry's ligament. After that, intratumoural dissection of Rt. RLN and end to end anastomosis of Lt. RLN were performed with microscopy to preserve the functions of RLNs as much as possible, otherwise permanent bilateral VCPs were inevitable. We report this case, since both vocal cords recovered from VCPs with symmetric, synchronous movements at postoperative follow up.

Background: Patients who have rotator cuff arthropathy experience a limited range of motion (ROM) of the shoulder joint and experience problems in performing their daily activities; however, no evidence is available to suggest the exact ROM of the shoulder joint in this population. Therefore, this study sought to determine the degree of motion of the shoulder joint in three planes during different activities. Methods: Five subjects with rotator cuff injuries participated in this study. The motion of the shoulder joints on both the involved and normal sides was assessed by a motion analysis system while performing forward abduction (task 1), flexion (task 2), and forward flexion (task 3). The OpenSIM software program was used to determine the ROM of the shoulder joints on both sides. The difference between the ranges of motion was determined using a two-sample t-test. Results: The ROMs of the shoulder joint in task 1 were 93.5°±16.5°, 72.1°±2.6°, and 103.9°±25.7° for flexion, abduction, and rotation, respectively, on the normal side and 28°±19.8°, 31°±31.56°, and 48°±33.5° on the involved side (p<0.05). There was no significant difference between the flexion/extension and rotation movements of the shoulder joint when performing task 1. However, the difference between flexion and rotation movements of the shoulder joints for the second task was significant (p>0.05). Conclusions: Those with rotator cuff arthropathy have functional limitations due to muscle weakness and paralysis, especially during the vertical reaching task. However, although these individuals have decreased ROM for transverse reaching tasks, the reduction was not significant.

Vocal fold injection (VFI) is widely accepted as a first line treatment in treating unilateral vocal fold paralysis and other vocal fold diseases. Although VFI is advantageous for its minimal invasiveness and efficiency, the invisibility of the needle tip remains an essential handicap in precise localization. Real-time light-guided vocal fold injection (RL-VFI) is a novel technique that was developed under the concept of performing simultaneous injection with precise placement of the needle tip under light guidance. RL-VFI has confirmed its possibility of technical implementation and the feasibility in injecting the needle from various directions through ex vivo animal studies. Further in vivo animal study has approved the safety and feasibility of the procedure when various transcutaneous approaches were applied. Currently, RL-VFI device is authorized for clinical use by the Ministry of Food and Drug Safety in South Korea and is clinically applied to patients with safe and favorable outcome. Several clinical studies are currently under process to approve the safety and the efficiency of RL-VFI. RL-VFI is expected to improve the complication rate and the functional outcome of voice. Furthermore, it will support laryngologists in overcoming the steep learning curve by its intuitive guidance.

This study shows that oriental medical treatment affected a patient with headache, dizziness, dim eyes, facial palsy and hard-of-hearing caused by traumatic temporal and occipital bone fracture. Traumatic facial palsy mainly occures by temporal bone fracture. Facial palsy caused by traumatic temporal bone fracture corresponds to gu-an-wa-sha (口眼?斜)of oriental medicine. Functional disorder of an auditory organ corresponds to yi-rong(耳聾) and hyun-hoon(眩暈) of oriental medicine. In general, everyone consider surgical operation first of all, in the case of having traumatic facial nerve paralysis. But, this case shows that oriental medical treatments(acupuncture and herbal medicine) have a good effect on a patient with traumatic temporal and occipital bone fracture.

The Drosophila temperature-sensitive mutant shibire (shi) is paralyzed at restrictive temperature by a reversible block in synaptic transmission. To explore the functional relationship among shi gene products, viability and temperature-sensitive paralytic behavior were quantitaively analyzed for four shi alleles, shi$^{ts1}$, shi$^{ts2}$, shi$^{ts4}$, and shi$^{ST139}$, and their heteroallelic combinations. The hemizygous combination of shi alleles over deficiency was not completely lethal. shi$^{ts2}$ exhibited distinctively higher viability than other alleles. A novel behavior, bang sensitivity, was also found in shi/Df(1). This bang-sensitive paralytic behavior was compared with that of the typical bang-sensitive mutant flies. Heterozygotes, shi/+, are more severe in temperature sensitivity than deficiency hemizygotes, Df(1)/+. Heteroallelic combinations of shi were less sensitive to high temperature than homozygotes. Among all allelic combinations, shi$^{ts2}$/shi$^{ts4}$ showed an unexpected extreme reduction in temperature sensitivity. The results of allelic interactions among 4 shi alleles suggest that the shi mutations examined behave as antimorphic alleles and that the gene product of shi are likely to function in multimeric forms.
