Low level laser therapy has various therapy effects. This paper performed the basic study for fabricating the low level laser therapy apparatus, and one of the goals of this paper was to make this apparatus used handily. The apparatus has been fabricated using the laser diode and microprocessor unit. The apparatus used a 7850m Laser diode for blood stream improvement and was designed for a pulse width modulation type to increase stimulation effects. In result, we could get the light power of 785nm wavelength.

Low level laser therapy has various therapy effects. This paper performed the basic study for fabricating the low level laser therapy apparatus, and one of the goals of this paper was to make this apparatus used handily. The apparatus has been fabricated using the laser diode and microprocessor unit. The apparatus used a 635 nm laser diode for laser medical therapy and was designed for a pulse width modulation type to increase stimulation effects. In this study, the designed device was used to find out how 635 nm laser diode affected the skin injury of SD-Rat(Sprague-Dawley Rat). We divided the participants into two groups; irradiation group which was irradiated 10 minutes a day for 9 consecutive days, and none irradiation group. The results showed that the study group had lower incidence of inflammation and faster recovery, compared with the control group.

This paper performed the basic study for fabricating the low level laser therapy apparatus, and one of the goals of this paper was to make this apparatus used handily. The apparatus has been fabricated using the 655nm laser diode and microprocessor unit. The apparatus used a 655 nm laser diode for laser medical therapy and was designed for a pulse width modulation type to increase stimulation effects. And then, each experiment was performed to irradiation group and non-irradiation group for cells. MTT assay method was chosen to verify the cell increase of two groups and the effect of irradiation on cell proliferation was examined by measuring 590nm transmittance of ELISA reader. As a result, the cell increase of cells was verified in irradiation group as compared to non-irradiation group.

MET is one of the few physical therapy having its own criteria. Mr. Holten approached the Norwegian Health Authority in 1967 to get his MET System recognized as a treatment method of its own. He was granted his approval for his exercise system's specivic criteria connecteed with the treatment method. In MET, the patient exercises himself without manual participation by physiotherapists, however, under continuous supervision.. The apparatus should be designed that functional quality (arthrogenous, circulatory, respiratory, neuromuscular) in question is optimally influenced when the patient carries out exercise in a certain range against a graded resistance. The therapy reassesses the scheme of treatment at least every fifth session and the maximum number of patients being 5 person per hour. The important principles in medical exercise Therapy are stabilization of hyperfunction through the system of autostabilization and mobilization of hypofunction through automobilization. In MET excrcises are adjusted to the patient's reactions. MET equipment is therefore made to meet requirements for treating patients with painful pathological dysfunction in the musculo-skeletal system.

We developed the 4channel Light Medical Therapy Apparatus for External Injury Cure using a high brightness LED. This equipment was fabricated using a micro-controller and a high brightness LED, and designed to enable us to control light irradiation time, intensity, frequency and so on, Especially, to control the light irradiation frequency, FPGA was used, and to control the change of output value, TLC5941 was used. Control stage is divided into 4 levels by program. Consequently, the current value could be controlled by the change of level in Continue Wave(CW) and the output of a high brightness LED could be controlled stage by stage. Compared with one LED irradiation, several LEDs irradiation could increase optical power.

To investigate anti-stress effects of Manual Kigong, Manual-Apparatus Combined Kikong, and Systemic Kigong, this experiments were performed changing of plasma catecholaminess and serum cortisol measured. Also using D.I.T.I(Digital Infrared Thermongraphy Imaging), Pulse Analyzer, Electric Current on Neurometer, and Digital Flicker on Testing-Stressed. And following results were abtained. 1) Menual-Appartus Combined Kikong decreased significantly increasing concentration of plasma epinephrine and norepinephrine level in Testing-stressed. 2) Manual Kigong decreased increasing concentration of serum cortisol level in Testing-stressed. 3) Manual Kigong and Manual-Aparatues Combined Kikong increased decreasing thermomerty on the palm's center caused Testing-stressed. 4) All of three treats are small change in SET(Systolic Ejection Time) by Pulse Analyzer caused Testing-stressed. 5) More changes of Electric Current on the Neurometer Diagnosis caused Testing-stressed are as followed. Manual-Apparatus Combined Kikong >Systemic Kigong >Manual Kigong From the results, it may be concluded that Manual-Apparatus Combined Kikong Theraphy having more anti-stress effects than Manual Theraphy. Systemic Kigong Therapy.

Ilizarov limb lengthening has been the new method to deal with a variety of orthopaedic problems. Ilizarov apparatus consists of stainless steel rings that surround the limb and are interconnected by threaded rods. Tensioned wires pierce the bone in the plane of each ring and are tightly attached to the ring. Ilizarov has reported distraction osteogenesis with the use of the typical fixator that allows functional loading. The purpose of this commentary is to introduce a four-stage rehabilitation protocol currently used by the authors in the physical therapy management of a post -limb lengthening. Each treament stage corresponds to a medical stage in the lengthening process. Treatment goals for each of the physical therapy treatment stage are presented to guide treatment planning. Two case examples are presented to illustrate the use of the management goals in treatment planning.

The authors studied 74 patients with cal therapy Kosin University Medical March 1994 through February 1995. The results were, as follows: 1. Average age of the subject patients was 59.3 years old, their age ranged from 20 to 84 years old, and the incidence between male and female was 1:1.24 2. In respect to the economy level the middle class revealed the highest incidence, 40(54%) in 74cases. 3. The cause of injury revealed the highest incidence in hypertension 52 patients(72 %), more than all revealed the highest incidence 23 patients(44 %) in 60th years old. 4. The form of injury revealed the highest incidence in infarction 36 patients(49 %), more then all revealed the highest incidence 13 patients (36 %) in 60th years old. 5. As for the region cerebral artery of infarction patients, middle cerebral artery was the highest region of injury 72 %. 6. As for the physical paralysis side, the left side showed higher incidence 40 patients(54 %) compared to the right side 31 patients (42 %). 7. The period of therapy was 56 days, in average extending from 7 days to II months, nore then all there were the most numerous patients within 3 weeks 28 patients(38 %). 8. The upper side of the upper lims had improved 67 patients(91 %), the lower side 48(65 %). In the cases of the lower limb, the upper side had improved 70(95 %), the lower side 58(78 %). In short, patients had improved more the lower limb than the upper limb, the upper side(elbow and shoulder part) then the lower side(wrist and finger) of the upper limb. In the cases of the lower limb, patients had improved more the upper side (knee and hip part) then the lower side(foot and ankle) 9. In the cases of patients can be walking among subject patients 55(74 %) and patients cannot be walking 19 (26 %), In the cases of patients utilized assistant apparatus 34 (62 %) among self-walking, completely patients can be self-walking 21(28 %).

We developed the 4-channel Light Medical Therapy Apparatus for Skin Injury Cure using a high brightness LED. This equipment was fabricated using a micro-controller and a high brightness LED, and designed to enable us to control light irradiation time, intensity and reservation. In this paper, the designed device was used to find out how high brightness LED light affects the skin injury of SD-Rat(Sprague-Dawley Rat). In the experiment, $1\;cm^2$ wounds on the skin injury of SD-Rat(Sprague-Dawley Rat) were made. Light irradiation group and none light irradiation group divided, each group was irradiated one hour a day for 14 days. In result, compared with none light irradiation group, the lower incidence of inflammation and faster recovery was shown in light irradiation group.
