Purpose: This study aimed to investigate the effects of ankle stretching with intrinsic muscles on ankle range of motion, static and dynamic balance, and gait speed in chronic stroke patients. Methods: The participants were 20 chronic stroke patients, divided into two groups, 10 in the ankle stretching with intrinsic muscles group and 10 in the slant board exercise group. Both groups performed their respective interventions once daily, with three sets per session, five times a week for four weeks. Ankle range of motion, dynamic and static balance, and gait speed were measured before and after the intervention. An independent t-test was used to compare the results between the two groups before and after the intervention. Results: Both groups showed significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention (p < .05). The ankle stretching with intrinsic muscles group showed more significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention compared to the slant board group (p < .05). These results suggest that ankle stretching with intrinsic muscles may be more effective than the slant board for certain outcomes. Conclusion: Ankle stretching with intrinsic muscles is effective in improving ankle range of motion, dynamic and static balance, and walking speed.

PURPOSE: This study examined the immediate effects of thoracic mobility exercises on the thoracic range of motion and chest expansion to provide data on thoracic mobility exercises in adults. METHODS: Adults were assigned randomly to two groups: the group that performed thoracic mobility exercises (TME group; n=10) or the group that performed thoracic mobility exercises using balance tools (TMEB group; n=10). The exercises were performed for 10 min in three different positions. The range of motion and chest expansion were measured before and after the exercise. RESULTS: The within-group comparisons before and after the intervention showed significant differences in the range of motion measurements for lateral flexion and rotation in the TME and TMEB groups (p < .05); difference in measurements of chest expansion was observed only in the TMEB group (p < .05). No significant differences in the range of motion for flexion and extension were observed in either group or during chest expansion in the TME group (p > .05). The between-group comparisons showed a significant difference in left lateral flexion (p < .05), whereas no other measures differed significantly (p > .05). CONCLUSION: The TME and TMEB groups showed significant increases in the thoracic range of motion; the TMEB group showed a significant increase in chest expansion.

In this paper, we propose an adaptive search range allocation algorithm for high-performance HEVC encoder and a hardware architecture suitable for the proposed algorithm. In order to improve the prediction performance, the existing motion vector is configured with the motion vectors of the neighboring blocks as prediction vector candidates, and a search range of a predetermined size is allocated using one motion vector having a minimum difference from the current motion vector. The proposed algorithm reduces the computation time by reducing the size of the search range by assigning the size of the search range to the rectangle and octagon type according to the structure of the motion vectors for the surrounding four blocks. Moreover, by using all four motion vectors, it is possible to predict more precisely. By realizing it in a form suitable for hardware, hardware area and computation time are effectively reduced.

Purpose: In the process of replantation of the amputated fingertips, the primary concern was given to survival of the amputees, while the functional aspect of digits after the surgery has been easily neglected. Although an internal fixation with a K-wire is often a part of replantation of the amputated fingertips, little consideration had been given to the study of relationship between distal interphalangeal joint fixation and post operative range of motion. A comparative study in relation to post operative range of motion was done on two different groups, one group with K-wire insertion and the other group without a K-wire insertion at the distal interphalangeal joint. Materials and Methods: The study was done on the cases of a single digit amputation conducted at our institute (the age in the range of 10 to 60) in about four-year of time span from March of 2005 to March of 2009. The cases with a thumb replantation, osteomyelitis or articular surface injury have been excluded from this study. The cases of both head and shaft fracture, except the insertion site of tendon, of distal phalanx of internal fixation with a single K-wire were reviewed for this study. A group of 24 cases without distal interphalangeal joint fixation in comparison to a group of 22 cases with distal interphalangeal joint fixation was reviewed to assess the postoperative range of motion at distal interphalangeal joint on the 6th week after the surgery. And, on the 30th month after the surgery, a group of 10 cases without distal interphalangeal joint fixation in comparison to a group of 10 cases with joint fixation was reviewed. A K-wire was removed in about 5 weeks after the fracture was reunited under the radiographic image, immediately followed by a physical therapy. Result: The active range of motion for a group without interphalangeal joint fixation was measured $49.0^{\circ}$ on average, while $28.6^{\circ}$ was measured for a group with interphalengeal fixation on the 6th week after the surgery. On the 30th month after the surgery, the active range of motion was measured $52.0^{\circ}$ and $55.0^{\circ}$ on average for a group without and with interphalangeal fixation respectively. Conclusion: In the process of replantation of the amputated fingertips, short-term(on the 6th week) improvement of postoperative active motion of range can be expected in the cases without distal interphalangeal fixation in comparison to the cases of interphalangeal joint fixation with a K-wire. However, there seems to be no difference on motion of range in a long-term (on the 30th month) follow up period.

PURPOSE: The aims of this study were to assess the intra-tester and inter-tester reliability and validity of hip range of motion using a smart phone in hip operative patients. METHODS: Twenty-five patients (eight total hip arthroplasty and seventeen femur neck fracture) participated in this study. The range of motions in active and passive hip flexion, abduction and external rotation were measured with a goniometer and smart phone over two times by two observers. The intra-tester and inter-tester reliability were evaluated using the intraclass correlation coefficient (ICC2,1). The validity was measured by Pearson's correlation coefficient RESULTS: The intra-observer reliability was good in all measured items (ICC>0.78). The inter-observer reliability was high with ICC (>0.90). All correlation coefficients of smart phone and goniometer was greater than 0.85 and showed a significant positive correlation (p<0.01). CONCLUSION: The range of motion measurement with a smart phone showed acceptable reliability. Therefore, it could be convenient and have economical benefits to measure the range of motion of the hip joint using a smart phone.

Objective: This study was conducted to apply skin mobilization to patients with Axillary web syndrome following breast cancer resection and to see the resulting changes in pain and joint range of motion. Design: Single case study,pre-post comparison. Methods: The subject was a female patient in her 40s who performed a mastectomy after being diagnosed with breast cancer, and then complained of uncomfortable pain from the shoulder joint to the axilla and limited range of motion. To implement a skin mobilization, the palms were adhered to the inner half of the arm, the arms were raised to a pain-free extent, and skin mobilization was performed. The skin was pulled in the direction of axilla and kept for 5 seconds 10 times for a total of 2 sets. Immediate changes in range of motion and pain were identified. Results: Following skin mobilization, there was an immediate increase in range of motion (pre 116°, post 140°) and a decrease in pain (NRS pre 5, post 2). And also uncomfortable pain, which is hard to define in words, also seems to have improved. Conclusions: Skin mobilization, which considers skin mobility for patients with Axillary web syndrome, can be considered for improving range of motion and restoring function in patients with pain due to fibrous bands around veins and lymphatic vessels, and is recommended as a new intervention method not used as a conventional treatment.

To generate workspace analytically using the robot kinematics, data on range of human joints motion, especially range of two degrees of freedom motion, are needed. However, these data have not been investigated up to now. Therefore, in this research, we are to investigate an interaction effect of motions with two degrees of freedom occurred simultaneously at the shoulder, virtual hip(L5/S1) and hip joints, respectively, for 47 young male students. When motion with two degrees of freedom occurred at a joint such as shoulder, virtual hip and hip joints, it was found from the results of ANOVA that the action of a degree of freedom motion may either decrease or increase the effective functioning of the other degree of freedom motion. In other words, the shoulder flexion was decreased as the shoulder was adducted or abducted to $60^{\circ}C$TEX>or abducted from $60^{\circ}C$TEX>to maximum degree of abduction, while the shoulder flexion increased as the joint was abducted from $60^{\circ}C$TEX> to $60^{\circ}C$TEX> The flexion was decreased as the virtual hip was bent laterally at the virtual hip joint, and also did as the hip was adducted or abducted from the neutral position. It is expected that workspace can be generated more precisely based the data on the range of two degrees of joint motion measured in this study.

The purpose of this study was to compare kinematic characteristics on the limbs at 3 different walking speed during the energy and the normal walking. Eight subjects performed energy walking and normal walking at the slow speed(65 beats/min), the normal speed(115beats/min), the fast speed(160 beats/min). The 3-d angle was calculated by vector projected with least squares solution with three-dimensional cinematography(Motion Analysis corporation). The range of motion was calculated on the trunk, shoulder, elbow, hip, knee joint. The results showed that stride length was no difference of the two walking pattern. The duration of support phase was also no difference of the two walking pattern. The range of motion of shoulder joint significantly increased in the sagittal and frontal planes, and the range of motion of elbow joint significantly increased as the energy walking. The range of motion of hip joint had no significant difference in the any planes in changing of walking speed. But the most remarkable difference of the two walking patterns revealed at the trunk. The range of flexion/extension angle had significant increasing $2.36^{\circ}$ at normal speed, and the range of the right/left flexion angle had significant increasing below $4^{\circ}$ at the 3 walking speed, and The range of rotation angle had significant increasing $7.35^{\circ}$, $9.22^{\circ}$, respectively at the normal and slow speed. But there was no significant difference of range of motion at the hip and knee joints between energy walking and normal walking.
