ABSTRACT
OBJECTIVE: This study was designed to evaluate the relation of leg length discrepancy on ankle muscle strength. METHOD: Twenty four adult women were tested (12 leg length equality and 12 leg length discrepancy). Leg length was measured by tape ruler from anterior superior iliac spine to medial malleolus, three times by three different trained examiners. The muscle strength (bilateral ankle dorsiflexors and plantarflexors) was measured by using Cybex 340 dynamometer at 30 degree/sec and 120 degree/sec. RESULTS: The mean value of leg length discrepancy was 0.89+/-0.24 cm. In leg length discrepancy group, the peak torque of ankle plantarflexor were 44.50+/-20.94 Nm in long leg and 51.83+/-12.75 Nm in short leg at 30 degree/sec angular velocity (p<0.05). CONCLUSION: We concluded that there were significant increase in plantar flexor peak torques of short leg than those of long legs at 30 degree/sec (P<0.05). Perhaps the difference of the muscle strength might be due to compensatory mechanism of short leg in propulsion during gait.

OBJECTIVE: To evaluate the phonological characteristics of speech in patients with Parkinsonism, and to compare with the healthy elderly adults. METHOD: By measuring the sustained phonation, diadochokinesis, mean intonation difference (average difference in fundamental frequency between the last syllables of interrogative and declarative sentences), and speech rate using the IBM Speech Viewer III system in the seventeen patients with Parkinsonism and fifteen healthy elderly adults. RESULTS: (1) Ability to prolong vowels and intonation values were reduced in the Parkinsonism group as compared to the control group, (2) The diadochokinetic rate and speech rate failed to differentiate between two groups. CONCLUSION: The analysis of the phonological characteristics of speech in patients with Parkinsonism was valuable for the evaluation and treatment of dysarthria.

The purpose of this study was to detect where the center of pressure in foot would be located at the end point of loading response and the terminal stance by the dynamic plantar pressure measurement. Seventeen adults who had the usual feet without a pathologic gait were evaulated simultaneously by the motion analysis using VICON 370, and the plantar pressure measurement using EMED-SF. Two devices were set in the 60 Hz frame. The foot was divided into 3 different zones; hindfoot, midfoot, and forefoot. The end point of loading response was located at the 1.92+/-1.46 frame distal to the hindfoot- midfoot borderline. The end point of terminal response was located at the 2.27+/-1.96 frame distal to the maximal pressure points of metatarsal head. Authors could differentiate each period of stance phase; the initial contact, loading response, mid-stance, terminal stance, and preswing, using the analysis of center of pressure by the dynamic plantar pressure measurement.

OBJECTIVE: To compare the efficiency of a key-person method with the census method on the prevalence of physically disabled. METHOD: The residents of K-myeon, A-kyun, Kyungido were surveyed in May 1996 with a census method and of D-myeon in August 1997 with a key-person method. The enlisted people in this survey included 2563 persons in D-myeon and 2138 persons in K-myeon on Identification Number. RESULTS: The prevalences of the physically disabled were 2.61% of the population in D-myeon and 5.00% in K-myeon (chi-square test: P0.500). This result suggests that there is no meaningful difference in the prevalence of severely disabled between the two survey methods. CONCLUSION: The key-person method is as effective as the census method to survey the prevalence of severely disabled in rural communities and requires a less cost and man power.

OBJECTS: The purpose of this study is to estimate the values of foot pressure of the stance phase during a gait cycle in hemiplegic gait. METHOD: Thirty patients who had a stroke and forty healthy adults were evaluated by the EMED-SF system to analyze the stance phase of hemiplegic gait. The stance phase was evaluated by 6 points according to the foot pressure and center of pressure proposed by Lee et al.2) RESULTS: 1) In hemiplegics, the stance time of involved limb decreased compared with that of the uninvolved limb and increased that of control groups (p<0.05). 2) In hemiplegics, the midstance time increased but the loading response and terminal stance decreased compared with the uninvolved limb and controls (p<0.05). 3) In hemiplegics, the midstance time decreased and the loading response and terminal phase increased according to the increased Brunnstrom stage (p<0.05). CONCLUSION: The results showed that an analysis of stance phase by the measurement of plantar pressure was a valuable parameter in the gait analysis of hemiplegic patients.

OBJECTIVE: To evaluate and correlate three biochemical markers of bone turnover and bone mineral density in the lumbar spine. METHOD: Eighty seven adults with the low back pain(45 men and 42 women) were enrolled in this study. Bone mineral density in the lumbar spine was evaluated by a quantitative computed tomography. Serum osteocalcin, serum alkaline phosphatase, and urinary deoxypyridinoline were measured in the early morning. RESULTS: The mean serum osteocalcin values were 5.61 ng/ml in men and 5.68 ng/ml in women. The mean urinary deoxypyridinoline values were 6.54 nM/mM.Cr. in men and 10.0 nM/mM.Cr. in women. Among women, the values of serum osteocalcin and alkaline phosphatase were significantly higher in the postmenopausal group than the premenopausal group(p<0.01). And, they were inversely related to bone mineral density in lumbar spine. CONCLUSION: These findings suggest that the measurement of serum osteocalcin, alkaline phosphatase, and urinary deoxypyridinoline can be used as indirect indicators of the current bone status, and can be effectively used in the evaluation and treatment of osteoporosis.

Dysphagia is a disorder of the swallowing mechanism and presents a major problem in the rehabilitation of stroke patients. In-the present study, computerized laryngeal analyzer (CLA) was used for noninvasive assessment of the pharyngeal phase of the swallowing mechanism. Laryngeal elevation was measured with pressor sensor placed on the skin over the thyroid cartilage. In the study. CLA was applied at each posture of neck flexion, neutral, and extension in stroke group and control group. Significant differences were found in each of the these parameters measured in control group and stroke group. The quantitative measurements may aid the physician in choosing the appropriate therapy during the course of recovery. The onset latency of swallowing was delayed in stroke group than control group at all posture of neck(p0.05). The amplitude of swallowing was decreased in stroke group at extension and neutral posture of neck compared to those of control group (p0.05).

The purpose of this study was to estimate mean pressure thresholds over several skeletal muscles, grip and pinch strengths in female telephone operators. Pressure thresholds on muscles of neck and shoulder were measured with a pressure algometer, and grip and pinch strength were measured with a Jamar dynamometer and a Jamar pinch gauge in 904 female telephone operators. The pressure threshold was highest in the supraspinatus and lowest in the cervical paraspinals. There was no statistically significant difference between right and left corresponding muscles. The mean grip strength was 22.29 kg in the right hand, 21.97 kg in the left hand. The mean tip pinch strength was 0.56 kg in the right, 0.51 kg in the left. The mean lateral pinch strength was 2.21 kg in the right, 2.12 kg in the left. The mean palmar pinch strength was 1.82 kg in the right, 1.66 kg in the left. There was no significant correlation between grip, pinch strength and age(p>0.05). There were positive correlations between height, weight and grip strength. There were positive correlations between exposure duration to visual display terminal and pinch strength.

To quantitively evaluate the initiation failure in Parkinson's disease (PD), we studied the initiation time by using the Cybex isokinetic test machine. Eighteen patients with idiopathic PD and age-matched normal controls were selected, and the initiation time during the extension and flexion of elbow and knee joints were measured in each group. Compared to the normal subjects and the patients with PD, the patients revealed prolongation of initiation time. So, it is suggested that the quantitive measurement of initiation time by Cybex isokinetic test could be a useful clinical tool in evaluating the symptoms of initiation failure of PD.

OBJECTIVES: Aims were to evaluate foot deformity in patients with rheumatoid arthritis for its types, prevalence, and relation with duration of the disease. METHODS: Inspection, measuring of hallux valgus and calcaneal angle and footprint were done on 256 feet of 128 patients with rheumatoid arthritis. Transverse (metatarsal) arch and longitudinal arch were evaluated by foot printings. RESULTS: 1) The most common type of foot deformities was hallux valgus in 175 of 256 feet(68.4%). Depressed transverse arches were in 169(66.0%), toe deformities including claw toe, hammer toe, curl toe and mallet toe in 125(48.9%), calcaneal valgus in 87(34.0%), callus in 67(26.2%), pes planus in 37(14.5%), and bunion in 25 (9.8%) of 256 feet. 2) Foot involvements as the initial manifestation were seen in 41 (32.0%) of 128 patients with rheumatoid arthritis. A duration of rheumatoid arthritis over 10 years were seen in 37 of 128 patients. In this patients mean number of involved toes per foot was 2.78 which was not statistically significant increase compared to that of all patients, 2.23 (p-value>0.05). Even with absence of foot symptoms in 28 of 128 patient with rheumatoid arthritis, toe deformities were seen in 1.55 toes per foot. And prevalence of hallux valgus, pes planus, depressed transverse arch and calcaneal valgus were 58.9%, 10.7%, 51.8% and 39.3% respectively. CONCLUSIONS: Foot deformities in patients with rheumatoid arthritis were usually inevitable complication. Even in the patients who had no foot symptom, there were foot deformities. So, we think that physicians should pay attention to the foot in all rheumatoid arthritis.

"Drop attack" is defined as sudden falling spell occurring without warning or postictal symptoms with immediate righting, and without loss of consciousness. Numerous mechanism have been proposed to explain the drop attacks. But there were no scientifically established answer for the extraordinary rapid evolution of the drop attacks. The authors report three cases of intracerebral mass lesions presenting with drop attacks. Among them, one was racemose brain abscess on the juxtaventricle of right parieto-occipital area in 3-year old girl, the another one was germinoma at genu portion of corpus callosum and pineal gland respectively in 20-year old male, and the remained one was neurocysticercosis around frontal horn of lateral ventricle in 60-year old male. The brain abscess and neurocysticercosis were almost totally removed, and conventional radio-therapy after stereotatic biopsy was carried out to germinoma of corpus callosum and pineal region. Drop attacks symptoms were abolished immediately after mass removal in brain abscess and neurocysticercosis, and gradually subsided in the germinoma case.

There are numerous theories of pathophysiology in intracranial aneurysm, but currently accepted hypothesis was congenital defect of medial layer of vascular wall and the major developing factor was hemodynamics. Almost physicians were belived that treatment of intracranial aneurysm was completely through clipping of aneurysmal neck. But many reports were emphasized newly deloped intracranial(De Novo) aneurysm after clipping of initially identified intracranial aneurysm. The authors have same experienced of 2 cases intracranial "Do Novo" aneurysms. We are stress there were never completed treatment of aneurysm that clipping of initially identified intracranial aneurysm and should be attention to "De Novo" aneurysm.
