The purpose of this study was to identify the saddle to pedal length contributing to successful performance in kayak using a kayak ergometer. Ten male elite kayak players participated in this study. players were tested on the kayak ergometer which was varied saddle to pedal length by the knee flexion angle(90deg; 120deg; 150deg) to measure stroke frequency, paddling amplitude, joint angle, RoM and angular velocity, foot pressure and force, iEMG using the 3D motion system, foot pressure system and EMG wireless system. At a results, rowing at 120deg on knee flexion angle showed higher stroke frequency and paddling amplitude than other knee flexion angles. RoM at upper extremity showed not significant difference between knee flexion angles. But there were significant differences in thorax and pelvis rotation RoM, knee flexion-extension RoM in each condition. In addition, foot pressure, force and iEMG were significantly different in knee flexion angles. Study showed that changed of saddle to pedal length affected rowing performance kinds of stroke frequency, paddling amplitude. The most important thing, increased range of motion in pelvic and thorax has occurred by force that generated foot-bar to seat. Not only that, but it seems to be attributed to a technical adaptation developed to maximum rowing performance.

Purpose: This study was to investigate the effect of isometric exercise and active stretching on joint function in patient with osteoarthritis. Methods: 30(M=1, F=29) subjects with osteoarthritis were divided in three groups: control group, quadriceps isometric exercise group, and hamstring active stretching group. After 6 weeks treatment, ROM(range of motion) and LSS(lysholm scoring scale) were measured. Results: There was a significant increase in knee flexion, extension in post-treat of quadriceps isometric exercise group and hamstring active stretching group(p<0.05). There was a significant increase in LSS in post-treat of quadriceps isometric exercise group and hamstring active stretching group(p<0.05). Conclusion: This study shows that both the active stretching exercise and the quadriceps isometric exercise effectively promote the range of knee extensions for osteoarthritis patients. Also, as measuring the ROM of knee flexion and extension by exercise methods, there is significant increase from knee flexion and extension in both hamstring stretching exercise group and quadriceps isometric exercise group. The increase of the range of knee is more effective in the exercise of knee extension with hamstring stretching exercise groups. And it is found that there are some difference between the experimental group and controlled group in statistics. As it is concerned with the function of knee extension, supporting and squatting are more effective to promote the both knee extension and flexion in its range. Therefore, this shows that the hamstring stretching exercise is required in general with enforcing the quadriceps at a sickbed in the present.

Objectives The purpose of this study was to report the effect of Korean medicine treatment, including the application of joint mobilizing chuna, by reporting two cases after tibial plateau fracture surgery. Methods Two patients with tibial plateau fractures were treated using joint mobilizing chuna, myofascial chuna, acupuncture, and herbal medication. The effect of the treatments was evaluated using the range of motion, manual muscle test, numeric rating scale, and Korean Knee Injury and Osteoarthritis Outcome Score. Results In both cases, the range of motion, muscle strength, and pain were significantly improved. In particular, the range of motion for knee joint flexion increased by 47° in case 1 and 30° (right) and 42° (left) in case 2. Conclusions Korean medicine treatment, especially joint mobilizing chuna, may be an effective intervention for rehabilitation after tibial plateau fracture surgery.

It is general knowledge that knee joint pain can be attributed to trauma and degenerative change around the knee joint. However most patients who have suffered from pain or limited range of motion of the knee joint show no definite pathology on X-ray or laboratory examination. We examined 242 patients with knee joint pain and found compression or entrapment of the articular nerve fiber by the tissue around the knee joint resulted in pain in almost all cases. Conclusion: by relieving the compression of the articular nerve fiber with just physical therapy and LASER stimulation on the identified trigger points, in conjunction with NSAIDs, muscle relaxants, were found to be very effective in the treatment of knee joint pain.

The number of knee-related disease patients and knee joint surgeries is steadily increasing every year, and for knee rehabilitation training for these knee joint patients, it is necessary to strengthen the muscle of vastus medialis and quadriceps femoris. However, because of the cost and time-consuming difficulties of receiving regular hospital treatment in the course of knee rehabilitation, we developed knee exoskeleton using rapid prototype for knee rehabilitation with feedback from the electromyogram (EMG) and inertia motion unit (IMU) sensor. The modules was built on the basis of EMG and an IMU sensor applied complementary filter, measuring muscle activity in the vastus medialis and the range of joint operation of the knee, and then performing the game based on this measurement. The IMU sensor performed up to 97.2% accuracy in experiments with ten subjects. The functional game contents consisted of an exergaming platform based on EMG and IMU for the real-time monitoring and performance assessment of personalized isometric and isotonic exercises. This study combined EMG and IMU-based functional game with knee rehabilitation training to enable voluntary rehabilitation training by providing immediate feedback to patients through biometric information, thereby enhancing muscle strength efficiency of rehabilitation.

Purpose: This report presents the authors' experience of twelve patients with sural artery flap for soft tissue defects around the knee joint. Materials and Methods: The patients' age ranged from 25 to 80 years; seven of the patients were male and five were female. The cause of soft-tissue defects involved wide excision for malignant soft tissue tumor, tumor prosthesis related infection, infection after total knee arthroplasty and chronic osteomyelitis. Postoperative range of motion was checked. The sensibility of flap was evaluated by Semmes-Weinstein monofilaments and two-point discrimination. Results: All flaps survived and provided satisfactory coverage of the defect. There was no complication except one delayed skin graft incorporation at donor site. Seven knee joints which had been stiff previously gained average 58 degrees of ROM postoperatively. All flaps retained sensibility and showed no significant increase in sensory thresholds comparing with contralateral side. Conclusion: Sural artery flap not only shows high survival rate and broad coverage ability, but also offers improvement in range of motion and preservation of sensation. We speculate that sural artery flap is valuable for the reconstruction of the soft tissue defects around knee joint.

Purpose : The purpose of this study was to compare the influence of Contract-Relax Technique of PNF(Proprioceptive Neuromuscular Facilitation) and taping treatment on the ROM(Range of Motion), pain and gait speed of osteoarthrits of knee. Methods : In this study K hall for the aged were selected. Twenty-six subjects with osteoarthrits participated in the experiment. The subjects were partitioned into two groups are 13person PNF group and 13person taping group. All subjects randomly assigned to the PNF treatment group and taping treatment group. Both group received treatment for 3times a week during 4 weeks. (PNF group received treatment for twenty times at once). Algometer and VAS(Visual Analogue Scale) were used to measure pain, the ROM was meaured using goniometer and gait speed was measured using a stopwatch (30m-test). All measurements of each subject were measured at pre-treatment and post-treatment. The data were analyzed with SPSS WIN 11.5 using t-test. Results : The PNF group had a significantly increase of knee extension ROM and significantly decrease of pain after treatment 4 weeks(P<0.05). The taping group had a significantly increase of knee extension ROM and gait speed and significantly decrease of pain after treatment 4 weeks(P<0.05). Conclusion : These data suggests that PNF is beneficial to increase knee extension ROM and to decrease pain. Taping is beneficial to increase knee extension ROM and gait speed and to decrease of pain.

There has been a controversy about the effectiveness of the synovectomy of the knee in the rheumatoid arthritis. So we studied to determine if the arthroscopic synovectomy of the knee was of benefit in the rheumatoid arthritis. We ana lysed 25 knees of 15 patients who underwent the arthroscopic synovectomy of the knee joint for their rheumatoid arthritis from Jun. 1995 to Oct. 1996. The average follow-up period was 20.1 months($12\~28$ months). The results were as follows; 1. Satisfactory results were obtained in 20 knees $(80\%)$ for the pain and the effusion each, 23 $(92\%)$ for the range of motion and 19 $(76\%)$ for the functional capacity. 2. In the overall results for the pain. effusion. range of motion and the functional capacity. we obtained excellent results in 14 knees $(56\%)$ and satisfactory results in 9 knees $(32\%)$. 3. In the patient's self assessment, 11 patients $(44\%)$ were delighted and 10 patients $(40\%)$ were satisfactory. 4. In the overall results according to the articular cartilage damage, satisfactory results were obtained in 15 $(93\%)$ out of 16 knees in Grade I and II, and 6 $(75\%)$ out of 8 knees in Grade III and IV. In conclusion, arthroscopic synovectomy could be one of very useful treatments for the rheumatoid knee. But further study is needed to get the long-term results of the synovectomy because there's many reports saying gradual decrease of good results with increasing time. And continuous and proper medical treatment including DMARDs, is needed to effectively control the rheumatoid arthritis even after the synovectomy.

This study was conducted to evaluated the effects adding continuous passive motion(CPM) each day to the entire postoperative program of patients who received a total knee replacement(TKR). A retrospective chart review was completed for 31 patients(12 with bilateral involvement, totaling 44 knees)who received a TKR between 1996 and 1998. The data analysis compared the following variables for 28 patients who received CPM and 16 patients who received no CPM: the length of hospital stay(LOS), the frequency of postoperative complications, the number of post-operative days(PODs) range of motion (ROM). The CPM Group showed significant decreases in the frequency of complication(p<0.05), the LOS(p < 0.05), and No difference was demonstrated in the ROM of the two groups. We concluded that CPM was an effective adjunct to physical therapy care of patients undergoing total knee replacement.
