Purpose : The purpose of this study was to analyze the dynamic range of motion (ROM) of pelvic and translation of center of mass (COM) when wearing different shoe insole lifts according to leg length discrepancy (LLD) during free speed gait. Methods : Thirty-five healthy adults were participated in this study. Kinematic data were collected using a Vicon motion capture system. Reflective and cluster 40 markers attached to participants lower extremities and were asked to walk in a 6 m gait way under three different shoe lift conditions (without any insole, 1 cm insole, and 2 cm insole). The pelvic ROM and COM translation in three planes were sorted using a Nexus software, and a Visual3D motion analysis software was used to coordinate all kinematic data. Results : There were significantly increased maximal pelvic elevation and total pelvic range in coronal plane when wearing a standard shoe with 2 cm insole lift during gait (p<.05). When wearing a standard shoe with 2 cm insole lift, the total range of the pelvic segment were significantly different in all three motion planes (p<.05). Conclusion : Although LLD of less than 2 cm develops abnormal movement pattern of the pelvis and may cause of musculoskeletal diseases such as low back pain, hip and knee joint osteoarthritis, therefore intensive various physical therapy interventions for LLD are needed.

Purpose: The purposes of this study were to establish the concurrent validity of the universal goniometer and electronic inclinometer for ankle joint of motion, and to determine the inter-tester and the intra-tester reliability of these two instruments. Methods: Subjects were instructed 25 healthy subjects. Ankle range of motion was measured on two separate occasions 2 or 3 days by two physical therapists. Ankle dorsiflexion and plantarflexion was by using an universal goniometer and an electronic inclinometer. Results: The Pearson product-moment correlation between the two instruments was 0.78~0.80. The ICCs for inter-tester reliability ranged from 0.63 to 0.73 for universal goniometer and ranged from 0.81 to 0.88 for electric inclinometer. The ICCs for intra-tester reliability showed a wide variation(ICC=0.61 to 0.86). Conclusion: These findings indicate that the two instruments are reliable instruments for measuring ankle joint range of motion. The results also indicate that the two instruments can be used interchangeably for measuring ankle motions.

Purpose : The purpose of this study was to examine the effect of upper extremity exercise and Bandage on the edema and range of motion. Complex decongestive physiotherapy was one of the latest methods to deal with the limitation of range of motion and the edema that were the prime problems of patients with lymphedema. Methods : Twenty patients undergone mastectomy were participated in this study voluntarily. They had lymphedema on upper extremity and partial limitation of range of motion. The subjects had been treated with upper extremity home exercise and complex decongestive physiotherapy with Bandage for 4 weeks. The measure of these patients with upper extremity edema was included: the volume, arm circumfenence and range of motion. These were measured two times: before the treatment, after 4 weeks of the treatment. Results : The upper extremity edema of patients treated home exercise group and complex decongestive physiotherapy group with Bandage was definitely decreased (p<0.05). Moreover, the upper volume of those who were the same condition also significantly shrank and patients' arm circumferences of upper arm breathtakingly diminished as well (p<0.05). But home exercise group patients' arm circumferences of forearm was not remarkable(p>0.05). However, patients' range of motion who were treated with upper extremity exercise were evidently increased when compared to that of the before treatment (p<0.05). Conclusion : Complex decongestive physiotherapy and bandage performed by physical therapist increased the ROM of upper arm and reduced the edema in patients with lymphedema.

Purpose: To determine the correct measurement methods of the ankle joint complex range of motion for measuring the neutral position and evaluate the rater reliability. In addition, the impact of training on the rater reliability was also assessed. Methods: The subjects were eleven healthy women, who were evaluated by two physical therapists and one physical therapist recorded the results of the study. Standard goniometer was used as the measurement tool. The ankle and subtalar joint neutral position and the active range of motion of the ankle and subtalar joint were measured. Intra-rater reliability and inter-rater reliability measures were analyzed with intraclass correlation coefficients. Results: Intra-rater reliability and inter-rater reliability ranged from high to medium for the neutral position of the ankle joint complex. Intra-rater reliability for dorsiflexion and plantarflexion measurements was medium, while the inter-rater reliability was high. The range of motion of the subtalar joint was measured, and the intra-rater reliability and inter-rater reliability were low and medium, respectively Also, the intra-rater reliability was increased with formal training of the measurement techniques. Intra-rater reliability was reduced in case the raters had not undertaken the training. Conclusion: In summary, the results obtained with the measurement tools and joint measurement of position, indicate the consistency of repeated measurements made by the same observers. Under the same circumstances along with repetition of the same measurement technique during training caused an increase in the rater reliability of formally trained raters.

PURPOSE: This study aims to identify the immediate effects of thoracic mobilization according to segment on disabling low-back pain and the range of motion in patients with chronic low-back pain. METHODS: The participants were divided randomly into two groups: a group (N=12) with pain and disability between the 5th and 9th thoracic vertebrae (T5-T9) and a group (N=12) with pain and disability between the 10th and 12th thoracic vertebrae (T10-T12). The same experiment was conducted in both groups: 10 minutes of thoracic mobilization and 10 minutes of functional massage. The visual analogue scale (VAS) and range of motion measurements were applied to the participants in both groups. All participants were measured again immediately after the program was completed. RESULTS: In both groups, the VAS and range of motion measurements showed statistically significant improvement after the experiment (p<.05). No statistically significant difference was revealed between the two groups (p>.05). CONCLUSION: The results of this study confirmed positive and immediate effects of thoracic mobilization of patients with chronic low-back pain. But, no significant difference in the thoracic mobilization by segment between the two groups. Based on these results, thoracic mobilization could help to improve pain control and functional activity in patients with chronic low-back pain.

Background: This study compared the effects of trunk stabilization exercise and hip joint exercises on the range of motion of the lumbar spine, pain severity, and severity of disability in patients with chronic lower back pain. Methods: A total of 30 participants were enrolled and divided into group 1 (n=10), group 2 (n=10), and group 3 (n=10) were performed by each group thrice a week for a total of 8 weeks. Group 1 performed warm-up exercise (15 min), trunk stabilization exercise (25 min), finish-up exercise (15mins). Group 2 performed warm-up exercise (15 min), hip exercise (25 mins, finish-up exercise (15mins). Group 3 warm-up exercise (15 min), trunk stabilization and hip exercise (25 min), Finish-up exercise (15 min). Participants were assessed for the range of motion of the lumbar spine, pain severity (visual analog scale score; VAS), and severity of disability (Oswestry disability index score; ODI) before and after the interventions. Results: All three groups showed a significant increase in the range of motion of the lumbar spine, but there was no significant difference among the groups. Moreover, the severity of pain and ODI were significantly decreased in all groups; however, the intergroup differences were non-significant. Conclusion: The results from this study confirmed the effectiveness of trunk stabilization and hip joint exercise in improving the lumbar range of motion, pain severity, and chronic lower back pain in patients. Thus, trunk and pelvic stabilization exercises and hip joint exercise can be used as clinical practices to treat and prevent chronic lower back pain.

To compensate for the motion errors in hydrostatic tables, a method to actively control the clearance of a bearing corresponding to the amount of error using actively controlled capillaries is introduced in this paper. The design method for an actively controlled capillary that considers the output rate of a piezo actuator and the amount of error that must be corrected is described. The basic characteristics of such a system were tested, such as the maximum controllable range of the error, micro-step response, and available dynamic bandwidth when the capillary was installed in a hydrostatic table. The tests demonstrated that the maximum controllable range was $2.4\;{\mu}m$, the resolution was 27 nm, and the frequency bandwidth was 5.5 Hz. Simultaneous compensation of the linear and angular motion errors using two actively controlled capillaries was also performed for a hydrostatic table driven by a ballscrew and a DC servomotor. An iterative compensation method was applied to improve the compensation characteristics. Experimental results showed that the linear and angular motion errors were improved to $0.12{\mu}m$ and 0.20 arcsec, which were about $1/15^{th}$ and $1/6^{th}$ of the initial motion errors, respectively. These results confirmed that the proposed compensation method improves the motion accuracy of hydrostatic tables very effectively.

The purpose of this study were to determine the intra-rater and inter-rater reliability of shoulder passive range of motion measurement using the "Clinometer + bubble level", a smartphone application and to compare with the intra-rater and inter-rater reliability of measurement using a goniometer. Twenty six patients with stroke were recruited for this study. Two raters measured the passive range of motion of four types of shoulder movements (forward flexion; FF, abduction; ABD, external rotation at $90^{\circ}$ abduction; ER90 and internal rotation at $90^{\circ}$ abduction; IR90) using a goniometer and a smartphone to determine within-day inter-rater reliability. A retest session was performed thirty minutes later to determine within-day intra-rater reliability. The reliability was assessed using intraclass correlation coefficients (ICC) and the standard error of measurement (SEM). The ICC (2,1) for the inter-rater reliabilities of the goniometer and smartphone were good in FF and ABD [ICC (2,1)=.75~.87] and excellent in ER90 [ICC (2,1)=.90~.95]. The intra-rater reliabilities for the goniometer and smartphone were good or more than good, with an ICC (3,1) value >.75, the exception was IR90 measured by rater 2 on the smartphone. These results suggest that smartphone could be used as an alternative method tool for measurement of passive shoulder range of motion in patients with stroke.

Background : Patients with frozen shoulder have pain and limited range of motion (ROM) at the affected shoulder. Shoulder pain of these patients usually decreases with recovery of range of motion. The aim of this study is to identify effects of static stretching and hold-relax on recovering ROM and reducing pain of patients with frozen shoulder. Methods : In this study, 15 patients with frozen shoulder who were only treated with physical therapy were recruited. Patients who received any surgical procedure or hydrotherapy were excluded. The subjects were divided randomly into 3 groups; control(n=5), static stretching(n=5) and hold-relax(n=5) groups. Patients were treated with stretching and the total number of treatments was 12 times. The ROM was measured at baseline, after fourth, eighth and final treatments. Shoulder pain and disability index(SPADI) scores were assessed before and after doing all treatments. Repeated measures ANOVA was used to analyze ROM change within each group. Changes of ROM between groups was analyzed by one way ANOVA followed by post hot analysis(Tukey's HSD). SPADI score within each group analyzed using Wilcoxon signed ranks test. A p-value<0.05 was considered statistically significant. Study Design : Repeated measures design. Result : There were significant differences of ROM in both treatment groups except internal rotation of static stretching group. ROM was significantly increased in treatment groups compared with control group, but the difference of ROM change between two treatment groups did not differ significantly. SPADI scores for treatment groups significantly decreased compared with pre-SPADI score. Conclusion : The result suggests that hold-relax can be more effective than static stretching to recover range of motion and alleviate shoulder pain on patients with frozen shoulder.

PURPOSE: This study examined the effect of vibration stimulation of a vibration foam roller on the change in the range of motion of the ankle joint and proprioception in patients with chronic ankle instability. An additional aim was to provide basic data for rehabilitation programs for chronic ankle instability patients. METHODS: This study was a randomized crossover design of 22 patients with chronic ankle instability. All subjects were divided into a vibrating group, a non-vibrating group, and a control group. The vibration and non-vibration groups performed the interventions, but the control group did not. For the measurement, the range of motion and proprioception of the ankle joint was measured using an electronic protractor (Electrogoniometer, BPM Pathway, UK). RESULTS: The vibration group showed significant differences in the dorsiflexion angle, dorsiflexion proprioception, and plantar flexion proprioception (p < .05). The non- vibration group showed significant differences in the dorsiflexion angle and dorsiflexion proprioceptive sensation (p < .05). The vibration group and the control group showed significant differences in dorsiflexion proprioception and plantar flexion proprioception (p < .05). CONCLUSION: The range of motion and proprioception of the ankle joint were improved in the group that received vibration stimulation after the intervention than before the intervention. Future research will be needed on patients with various diseases.
