Purpose: The purpose of this study was to compare the effects of continuous passive motion(CPM) and continuous active motion(CAM) on proprioception of the knee after total knee replacement(TKR). Methods: Twenty patients with TKR were randomly allocated into two groups, the CPM group(n=10) and the CAM group(n=10). All subjects were evaluated for levels of pain, passive range of motion and angle reproduction of the knee. An angle reproduction test was used to assess the proprioceptive deficit. Two types of angle reproduction test were used: a passive angle reproduction(PAR) test and an active angle reproduction(AAR) test. The relevant examinations were performed before and after intervention(on the 5th day and the 10th day). The statistical significance were calculated using a t-test and a one-way repeated ANOVA. Results: A pre-intervention significant difference was not found between the two groups. Significantly better results were before and after the intervention at 10 days, for the PAR(flexion direction) test; however, only in the CAM group. There were no significant difference, either before or after the intervention, for the AAR test(flexion and extension direction) in both group. Both groups experienced similar levels of pain and passive range of knee motion before and after the intervention. Conclusion: This study revealed that CAM was a better effect to restore position sense of the knee joint after TKR.

The purpose of this study was to investigate the effect of lumbar stabilization training and additional thoracic mobilization on pain, proprioception and static balance in patients with chronic low back pain. The subjects of this study were 48 chronic low back pain patients who were randomly allocated to an experimental group 1 ($n_1=16$, lumbar stabilization and thoracic mobilization, thoracic hypomobility), experimental group 2 ($n_2=16$, lumbar stabilization and thoracic mobilization, thoracic normal mobility), and a control group ($n_3=16$, lumbar stabilization, thoracic hypomobility) after a thoracic mobility test. Both experimental groups underwent lumbar stabilization training and additional thoracic mobilization. The control group underwent only lumbar stabilization training. The intervention was performed 3 times per week, 30 minutes each time, for a total of 6 weeks. Thoraco-lumbar joint reposition error was measured using an electrogoniometer and static balance ability was measured using the Tetrax posture analysis system. Subjects' pain level was measured using a 100 mm visual analogue scale. Statistical analyses were performed using a one-way analysis of variance and a paired t-test. Post-hoc testing was carried out with a Bonferroni test. The pain level was significantly lower in both experimental groups compared to the control group. Both experimental groups showed significant reductions in joint reposition error angle (flexion, extension, and side bending) compared to the control group. The static balance level was significantly lower in both experimental groups than in the control group. In summary, lumbar stabilization exercises and additional thoracic mobilization significantly improved the pain level, proprioception, and static balance in patients with chronic low back pain.

Purpose : The purpose of the present study is to report the effect of proprioception of ankle after kinesiotaping application on ankle. Method : This study has conducted to target 30 average adult subjects with no damage to the ankle joint (16 males and 14 females). The group is divided into experimental group and sham groups in random way. The subjects in the experimental group are applied taping kinesiology on ankle joint. The subjects in the sham group are applied a sham taping on the ankle joint which is not actually affected for real ankle joint problem. Each subjects in both groups has tree trials in plantarflexion, dorsiflexion, inversion, and eversion before and after application of the kinesiotaping or sham taping of the bare footed ankle. The outcome were determined from the difference between the target angle and the trial angle produced by the subject. Results : These results from the experiment shows that the experimental group compared to the difference in kinesiotaping angle values were significantly different from each dorsiflexion (DF), eversion (EV) (p<.05). Otherwise, in the sham group did not produce significant differences in any joint movement. In addition, when we compared between two groups (the experimental and sham groups), it did not show that there was significant differences. Conclusion : First, there is no significant difference between the sham group and kinesiotaping group after proprioceptive tests. Second, even though there is no significant outcome in statistical analysis, there is actual differences in the experiment. This result might be ceiling effect, and if the kinesiotaping were applied to actual ankle injury patients, this taping treatment could be very effective for curing this patient.

Purpose: This study was an investigation of the effect of unstable supporting exercise in young adults with functional ankle instability. The study tested the use of a jumper and virtual reality (VR) training via a VR-head mounted display (HMD) system to provide functional improvement in proprioception, range of motion (ROM), ankle muscle strength, agility, and balance. Methods: The subjects comprised 61 young adults (in their twenties) with functional ankle instability to decide as less than 24 points using Cumberland ankle instability tool. The subjects were divided into three groups: VUS (VR-HMD and unstable supporting exercise, n = 20), VSS (VR-HMD and stable supporting exercise, n = 19), and NUS (non-VR-HMD and unstable supporting exercise, n = 22). The exercise program was conducted three times per week for three weeks. VR training via a VR-HMD system and a VR application on a smart mobile device were used with the VUS and VSS groups, and unstable supporting exercise was used in the VUS and NUS groups for 30 minutes. Proprioception, ROM, ankle muscle strength, agility, and balance were measured before and after training. Results: The VUS group showed significant differences in most results, including proprioception, ROM, ankle muscle strength, agility, and balance to compare before and after, and the VSS and NUS groups partially. Moreover, the VUS group had significant differences in most results when compared with the other groups. Conclusion: Unstable supporting exercise and VR training via a VR-HMD system improved functional ankle instability in terms of proprioception, ROM, ankle muscle strength, agility, and balance.

The multiple acupuncture techniques have been used to relieve the pain of lateral ankle sprain. Recently, early functional rehabilitation is emphasized in rehabilitative concepts using active ROM, facilitated proprioception, alphabet exercise and so forth. Similarly, in oriental rehabilition medicine, traditional movement technique called "Dong-Ki" has been used to relieve pain of ankle sprain. So we used "Dong-Ki" technique with SSP(silver spike point) electrotherapy transformed from alphabet exercise and evaluated the effects in method of randomized controlled trials. Methods : 27 outpatients with lateral ankle sprains were randomized into two groups : 15 samples and 12 controls. Sample group was treated with "Dong-Ki" technique(writing his name with foot) with SSP electrotherapy to relieve pain during additionally. "Dong-KI". Outcomes were measured by 10cm VAS and ankle circumference(cm). Results : In terms of VAS, Sample group had inclination of pain relieving but not significantly meaningful. In terms of ankle circumference measurement, Sample group showed significantly improved.

Purpose: The purpose of the present study was to examine joint position senses and muscle activity in subjects with and without chronic low back pain and to determine the effects of different types of bridge exercises on their trunk muscle activity. Methods: Thrity-eight subjects with chronic low back pain and thrity healthy controls participated in the experiment. Joint position senses and trunk muscle activity levels were measured during the different bridge exercise methods. Results: The joint position senses of the healthy group and chronic low back pain group showed significant differences during lumbar flexion, lumbar extension, lumbar lateral flexion, and lumbar rotation. The muscle activity levels of the transversus abdominis (TrA), internal oblique (IO), and external oblique (EO) were highest in the prone bridge exercise (PBE) group, followed by the supine bridge swiss ball exercise (SBSE) group and supine bridge exercise (SBE) group in order of precedence. The muscle activity level of the erector spinae (ES) was highest in the SBSE group, followed by the SBE and PBE groups in order of precedence. Conclusion: Overall, the results suggest that chronic low back pain is associated with declines in joint position senses and that PBEs increase trunk muscle activity more than conventional bridge exercises.
