Purpose: This article was conducted to determine the immediate effects of unilateral contract-relax (CR) stretching on contralateral knee extension range and to compare both sides of the knee extension range between experimental and control groups. Methods: This study recruited 16 adult males and females with straight leg raising abilities below $90^{\circ}$. The subjects were randomly divided into an experimental group and a control group comprising 8 subjects each. The experimental group performed direct CR stretching on the right hamstring muscles with straight hip extension adduction, and the control group performed indirect CR stretching on the right hamstring muscles with straight hip flexion abduction. Each group performed CR stretching 4 times with 4 repetitions comprising 10 sec of contraction and a 10 sec break between repetitions. Before and after the CR stretching exercises, the subjects' passive knee extensions were measured at the hip in a $90^{\circ}$ flexed position. The subjects' peak force on the right leg and peak pressure on the left leg during each CR stretching exercise were also measured. Results: After doing CR stretching 4 times, each group showed a significantly increased passive knee extension range on both sides, and there was no difference in the passive knee extension ranges between the groups. The peak force on the right leg was significantly higher in the experimental group than the control group. There was no difference in peak pressure between the groups. Conclusion: After applying unilateral CR stretching, the study subjects experienced a significantly increased passive knee extension range on the contralateral side. For patients who find it difficult to apply stretching techniques to knee joints directly, the use of the proprioceptive neuromuscular facilitation technique of CR stretching may be useful in improving the range of the knee joint on the contralateral side without direct treatment.

Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) exercise on the range of motion (ROM), pain, and functional activity of patients who received total knee arthroplasty (TKA). The purpose of this study was to provide fundamental data regarding the use of PNF exercise among patients with musculoskeletal disease. Methods: Fourteen patients who received TKA were randomly divided into an experimental group (n=7) that took part in PNF exercise and a control group (n=7) that performed general rehabilitation exercise. Both groups performed the respective exercises for 30 minutes, five times a week for 2 weeks. For the measurement of ROM, the range of knee flexion was measured using a clinometer smartphone application. A visual analogue scale (VAS) was used for the measurement of the level of pain. The timed up and go test (TUG) was conducted to measure functional activity. A paired t-test was performed to compare within-group changes before and after the PNF exercise. Differences between the experimental group and control group were analyzed by an independent t-test. For all tests, the level of statistical significance was set at ${\alpha}=0.05$. Results: After the exercise, there was a significant within-group change in VAS and TUG scores in the experimental group and control group (p<0.01). There was also a significant between-group difference in VAS and TUG scores after the intervention (p<0.05). Conclusion: General rehabilitation exercise is commonly applied as a treatment for TKA patients and is relatively effective. The application of PNF exercise may be useful in such patients, considering its effects on ROM improvement, pain reduction, and functional enhancement.

Objectives This case study aimed to investigate the effect of complex Korean medicine therapy and fascia Chuna therapy on Osgood-Schlatter disease. Methods Hospitalization treatment was performed on a 13-year-old Osgood-Schlatter patient who visited Woosuk University Korean Medicine Hospital. The patient complained of pain in both the tibial tuberosity and restriction on the range of knee joint movement. The results were evaluated using the visual analogue scale, knee injury and osteoarthritis outcome score, and range of motion. Results After treatment, knee pain decreased and range of movement angle improved. Conclusions This study suggests that complex Korean medicine therapy, including myofascial Chuna therapy, are effective in improving the range of motion and improving pain in early Osgood-Schlatter disease. The limitation of this study is that the subject of the study was limited to one case. Further clinical studies are required.

The purpose of this research is to measure range of virtual hip joint and lower limb joints motion such as the hip, knee and ankle joints for 47 young male students. The results of ANOVA revealed that anthropometric dimensions including weight and stature did not show any significant effects on the range of virtual hip joint and lower limb joints motion and the range of motion with two degrees of freedom at the shoulder, virtual hip and hip joints. Anthropometric dimensions such as age, weight, statuire, arm length, shoulder height and leg length were found to be lowly correlated with the range of virtual hip joint and lower limb joints motion. It is expected that the data on the range of joint motion suggested in this study can be used as a valuable input data when designing workplace, predicting human posture and reach volume, etc.

Purpose: The purpose of this study is to investigate the level of pain, gait speed, and ROM (Range of motion) in community-dwelling older adults with knee joint pain. Methods: A convenience sample of 160 participants living in G city were recruited. Elderly people who suffer from knee joint pain with a pain level ${\geq}5$ during the last one year on a visual analogue scale were included in the study. The data were collected from June to August 2016. All statistical analyses were performed using IBM SPSS ver. 22.0. Results: Participants' pain was 6.81 by VAS. The mean gait speed was 13.9 sec/10m. The ROM of left knee and right knee were $54.06^{\circ}$ and $56.50^{\circ}$, respectively. The level of pain was different according to gender (t=-4.87, p<.001), economic status (t=3.51, p=.032), diseases (t=5.23, p<.001), diagnosis of arthritis (t=3.86, p<.001), region of knee joint pain (F=9.30, p<.001), duration of pain occurrence (F=13.82, p<.001), and limp (F=3.58, p<.001). The level of knee joint pain and gait speed had significant correlations. Conclusion: The gait speed in older adults is an important variable that should be taken into account in the assessment of their level of knee joint pain.

Purpose: The purpose of this research was to test the effects of ST35 & Sulan moxibustion on knee joint pain, range of motion, and discomfort during Activies of Daily Living (ADL) in elderly with knee joint pain. Method: A nonequivalent control group pre-post test research design was used. Thirty four elderly who had knee joint pain were studied. Of them, sixteen were in the experimental group and eighteen the control group. The instruments used for this study were NRS, goniometer, and a modified ADL questionnaire developed by Lee. Result: The pain scores of right & left knee joint after moxibustion were significantly different between the experimental group and the control group (Right: F=26.27, p=0.000, Left: F=20.77, p=0.000). Right and left knee ROM scores were significantly different between the experimental group and the control group after moxibustion (Right: F=10.74, p=0.003, Left: F=9.239, p=0.005). Discomfort during ADL scores were significantly different between the experimental group and the control group after moxibustion (F= 32.31, p=0.000). Conclusion: It is necessary that nurses provide the elderly with knee joint pain with moxibustion to reduce joint pain and to increase knee ROM as an alternative therapy.

The kinematics involved in different landing strategies may be related to the occurrence of trauma. Several sources suggest that the angle of knee extension on touchdown and impact with the ground determines the magnitude of the impact force and, indirectly, knee loading. This study compared the initial knee angle and maximum knee flexion angle at the instant of impact on drop-landings between healthy men and women. In this study, 60 participants (30 males, 30 females) dropped from a height of 43 cm. A digital camera and video motion analysis software were used to analyze the kinematic data. When landing, there was significant difference between the two groups ($15.67{\pm}6.05^{\circ}$ in male, $24.10{\pm}6.34^{\circ}$ in female) in the mean knee flexion angle. The range of knee flexion on landing ($44.06{\pm}10.97^{\circ}$ in male, $36.96{\pm}9.99^{\circ}$ in female) also differed significantly (p<.05). The greater knee flexion that was observed in the male subjects would be expected to decrease their risk of injury. Women land with smaller range of knee flexion than men and this might increase the likelihood of a knee injury.

To investigate the effects of wearable near-infrared ray-emitting knee pads on knee pain among elderly adults in Korea. Randomized controlled trial evaluating the effects of near-infrared rays (NIR) on knee pain in Korean elderly adults. Five community-based research facilities (two welfare centers, a senior citizen center, and two churches). Forty-seven participants aged 65 years and older who had experienced knee pain. The experimental group (n = 25) wore NIR-emitting knee pads for one month at nighttime while sleeping. The control group (n = 22) wore knee pads without NIR. Demographic characteristics, intensity and duration of knee pain, amount of analgesic medication used, range of motion, gait speed, and health-related quality of life were collected using questionnaires. The experimental group showed decreased intensity (t = -6.17, p < 0.001) and duration (t = -3.34, p = 0.002) of knee pain and reduced analgesic use (t = -2.30, p = 0.026) compared to the control group. NIR may be an effective non-pharmacological option for relieving knee pain in elderly adults.
