Background: The purpose of this study was conducted to investigate the effects of the ankle mobilization with movement (MWM) technique on ankle dorsiflexion range of motion (ROM), balance, and gait in patients who underwent total knee replacement (TKR). Methods: Thirty patients with knee osteoarthritis were recruited and randomly divided into two groups: the experimental group (EG; n=15) and the control group (CG; n=15). For five days a week for 3 weeks, participants in the EG were treated with the ankle MWM technique and traditional total knee replacement (TKR) exercise, and those in the CG only performed traditional TKR exercises. The dorsiflexion ROM, balance, and gait of the patients were before and after exercise. Results: Balance system SD was used compare changes in dynamic balance. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in dynamic balance between the EG and CG groups after the intervention (p<.05). STT-IBS was used to compare changes in velocity, step length, stride length, and ankle dorsiflexion ROM. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in the velocity, step length, stride length, and ankle dorsiflexion ROM between the EC and CG groups after the intervention (p<.05). Conclusion: Our results showed that applying the ankle MWM technique with traditional TKR exercises improved ankle dorsiflexion ROM, dynamic balance, and gait in patients.

The purpose of this study was to determine the effect of electrical stimulation biofeedback on motor learning of quadriceps muscle isometric exercise in 3 patients who have undergone total knee replacement surgery. A multiple baseline design across subjects was used. The electrical stimulation biofeedback was provided with each patient during quadriceps isometric exercise, which last 10 to 14 sessions with 10 repetitions each sessions. After training patients received 4 retention tests. Maximum muscle activity was measured pre- and post- electrical stimulation biofeedback training and retention test to evaluate the effect of biofeedback training. Maximum isometric muscle activity of quadriceps was increased after electrical stimulation biofeedback training in all subjects. The results indicate that a electrical stimulation biofeedback training is a useful method to improve motor learning of quadriceps isometric exercise in total knee replacement.

Purpose: The purpose of the current study was to examine the effects of electromyography (EMG)-biofeedback training on lower extremity muscle activity and balance of patients with total knee replacement (TKR). Methods: Subjects were randomly allocated to two groups: experimental and control group. Subjects in the experimental group (n=10) were provided with quadriceps setting exercise by EMG-biofeedback (QSE+BF) and those in the control group were provided with QSE. Subjects in both groups were provided with the respective training programs for 20 minutes per session, five times per week, for a period of six weeks. To test significance, data analysis was performed using repeated-ANOVAs. Results: Statistically significant differences in muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability were observed in the experimental group, compared with the control group. In comparison of the muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability between different training periods within the groups, both groups showed statistically significant differences. Conclusion: EMG-biofeedback training is effective in improving lower extremity muscle activity and balance ability of patients with TKR, and should be effective in patients with other diseases.

본 연구는 슬링을 이용한 능동 운동프로그램이 무릎 관절 전치환술 환자의 통증과 균형에 미치는 영향을 알아보고자 실시하였다. 대상자는 무릎 관절 전치환술을 받고 입원 중인 환자 20명이며, 수술 후에 CPM (Continuous passive motion) 만을 적용하는 집단 (CPM group; CG)과 CPM과 슬링을 이용한 능동 운동프로그램을 병행하는 집단 (CPM with active exercise program using sling group; CSG)으로 10명씩 무작위로 배치되었다. CG는 CPM을 주 5일, CSG는 CPM을 주 2일, 슬링을 이용한 능동 운동프로그램을 주 3일 실시하였고, 각 중재는 하루 40분씩 총 4주간 실시하였다. 통증은 VAS(Visual analog scale)을 이용하여 평가하였고, 균형은 BT4 (Balance training 4)를 이용하여 C90 area, Trace length, Sway average velocity를 눈을 뜬 상태와 감은 상태로 측정하였다. 그 결과, 두 집단 모두 통증에서 집단 내에서 유의하게 감소하였고, 집단 간의 변화량에서도 유의한 차이가 있었다. 균형에서 CG의 C90을 제외한 모든 변인이 중재 후 유의한 변화가 있었으며, 집단 간 변화량에서는 눈을 감은 상태의 C90과 Vel에서 유의한 차이가 있었다. 따라서 CPM과 슬링을 이용한 능동 운동프로그램을 함께 시행하는 것은 무릎 관절 전치환술 환자의 통증 감소와 균형 향상에 효과적인 중재라고 생각한다.

Purpose: The objective of this study was to verify the effects of elastic-band exercise on pain, range of motion, and fear of falling in patients with total knee replacement. Methods: The study design was a nonequivalent control group non-synchronized quasi-experimental design. Data were collected from December 10, 2014 to January 10, 2015 in an orthopedic specialty hospital located in the C city. Forty-eight patients participated in the study, and each twenty-four were assigned to the experimental group and the control group. The elastic-band exercise was used with the experimental group for 10 days. The numeric rating scale was used to measure pain, goniometer to measure range of motion, and a questionnaire to measure fear of falling. The data were analyzed using $x^2-test$, Fisher's exact, t-test and paired t-test. Results: Compared to the control group, pain in the experimental group decreased (t=-2.89, p=.006), range of motion increased (t=2.98, p=.005), and fear of falling decreased (t=-4.63 p<.001). Conclusion: The elastic-band exercise for total knee replacement patients is considered to be an effective nursing intervention to decrease pain and fear of falling, and to increase range of motion.

The twenty one individuals with total knee replacement who were admitted to Kang-Dong Hospital for comprehensive physical therapy were studied in order to demonstrate the effectiveness of an isokinetic test program using the Cybex 6000 machine. The subjects were divided into three groups with the isometric exercise group receiving isometric exercise. the isokinetic eccentric exercise group, and isokinetic eccentric exorcise group receiving isokinetic exercise(eccentric. concentric) to knee flexors and extensors muscles for a six weeks period using the Cybex 6000. The results were follow :1 . The peak torque was increased significantly in the flexors and extensors of the isokinetic conccentric exorcise among three groups(p<.05). 2. The progress of peak torque was increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<.05). 3. The total work was more increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<.05). 4. The progress of total work was more increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<;.05). 5. The ratio of endurance was not increased significantly in all three groups. 6. The extensors in the peak torque was likely to recover rapidly than the flexors. 7.The average R.O.M in the pre-exercise and post-exercise was not different significantly in all three groups. According to the above results, In the muscle strength recovery for total knee replacement patients, isokinetic concentric exercise group was significantly greater than the isokinetic eccentric and isometric exercise groups after a six weeks training.
