Purpose: This study was to evaluate effects of myofascial release therapy for newborns and infants with congenital torticollis. Methods: In a two month period, thirty-six newborns and infants diagnosed with congenital muscular torticollis received treatment thirty times; then divided into a myofascial release group and stretching group. Crying frequency was used to measure the amount of crying time during treatment. Ultrasonography was used to measure the size of fibromatosis. Physical examinations were used to measure the degree of head tilting and rotation. Results: The results were as follows: 1. Crying frequency was significantly decreased in myofascial degree group. 2. The size of fibromatosis was not significantly decreased in ultrasonography. 3. Head tilt was significantly decreased in myofascial release group. 4. Rotation was not significantly increased in myofascial release and control group. Conclusion: The above results suggest that myofascial release therapy is helpful decreasing head tilt, crying frequency, and increasing head rotation.

Purpose: This study compared the different sling and resistance exercises on pelvic rotation during active straight leg raises (ASLR) and on pain in patients with chronic low back pain (CLBP). Methods: Twenty subjects were divided randomly into a sling group (SG) and a resistance exercise group (REG). Internal oblique (IO), external oblique (EO), rectus abdominis (RA), and rectus femoris (RF) muscle activity; pelvic rotation angle during ASLR; and visual analogue scale, pressure pain threshold were measured. Sling and resistance exercises were then performed for 30 minutes and the measurements taken again. Results: Both groups showed significantly lower RF muscle activity and significantly higher EO and IO muscle activity (p<0.05). The RA muscle activity decreased significantly in the SG, but increased significantly in the REG (p<0.05). The pelvic rotation angle was significantly lower in the SG (p<0.05). The pain press threshold increased significantly in both groups (p<0.05). The visual analogue scale decreased significantly in the SG (p<0.05). Conclusion: Both exercises appear to be beneficial for modifying the muscle activity and pain control in the intervention of CLBP. On the other hand, the sling was more effective in increasing the pressure threshold than resistance exercise, and the pelvic rotation angle was reduced. Therefore, both exercises can help patients with CLBP change their muscle activity and control pain. CLBP patients should use a sling for short periods of time to learn to reduce the pain and control pelvic rotation.

Frozen shoulder is clinically characterized by pain and reduced ROM. The therapeutic goal of frozen shoulder can be reducing pain and increasing ROM in shoulder joint, resulting in improvement of joint movement. Therefore, this study was conducted to know the effect of mobilization in parallel with conservative physical therapy(H/P, TENS, U/S) in patients with frozen shoulder on subjective pain scale and ROM. 26 patients diagnosed with frozen shoulder were included for study. Among them, 13 patients(experiment group) were managed by mobilization as well as conservative physical therapy, another 13 patients(control group) were only treated by conservative physical therapy alone. All the patients were treated three times a week for 4 weeks, and after each treatment subjective pain scale and ROM were measured. In experimental group, pain has decreased and ROM has increased in abduction, external rotation and internal rotation. In control group, pain has also decreased but ROM has not changed in abduction, external rotation and internal rotation. There were no significant difference in subjective pain scale between two groups but some difference in ROM (external rotation, internal rotation). According to the results, we concluded that both conservative physical therapy and joint mobilization technique are more effective for increasing ROM especially external rotation, internal rotation than conservative physical therapy alone.

Purpose: The purpose of this study was to evaluate effect of Thera-Band stretching exercise on flexibility of shoulder joint. Methods: The research deign was a experimental pre-post control group design. Sixteen subject were randomly divided into two groups; experimental group(n=8) and control group(n=8). Experimental group performed Thera-Band PNF stretching for 4 weeks and control group was not performed. To compare with the effectiveness of Thera-Band PNF stretching between two groups, I measured flexibility of shoulder joint with an Apley scratch test. The data were analyzed by Independence T-test. Results: The experimental group was significantly increased the flexibility at the right and left shoulder internal rotation. But the experimental group was not significantly increased the flexibility at the right and left shoulder external rotation. Conclusion: These result suggest that home-based exercise programs with Thera-Band can serve as a practical and effective means of flexibility gains in general people.

Object : Anterior cervical discectomy and fusion is accepted as appropriate surgical intervention for disease processes of the ventral cervical spine. In some cases, however, improvement of symptom following operation develop myelopathy or rhizopathy at longterm follow-up. We studied to clarify the correlation between clinical results and plain radiologic findings at long term follow-up. Methods : A total of 86 patients who underwent anterior cervical discectomy and fusion were grouped into deteriorated and good recovery group. These two groups were compared in lateral functional roentgenograms on the cervical kyphosis and disc height at fused level, sagittal plane rotation and dynamic sagittal canal diameter at adjacent level. Results : The presence of cervical kyphosis and disc height at fused level do not correlate with long term followup results. Sagittal plane rotation of more than 20 degrees were identified in 36% of the cases in deteriorated group, whereas the same findings were identified in 15% of the cases in good group. Sagittal diameter of less than 12mm were identified in 48% of the cases in deteriorated group, whereas the same finding were identified in 8% of the cases in good group. Preoperatively, sagittal plane rotation of more than 20 degrees at adjacent level were identified in 28% of the cases in deteriorated group, whereas the same findings were identified in 13% of the cases in good group. Preoperatively sagittal diameter of less than 12mm at adjacent level were identified in 40% of the cases in deteriorated group, whereas the same finding were identified in 7% of the cases in good group. Conclusion : Large sagittal plane rotation and small dynamic sagittal diameter at adjacent level were factors that might be associated with later clinical deterioration after cervical anterior fusion.

Purpose: The goal of this study was to evaluate differences in strength deficits between (i) patients with stage 1 or 2 impingement syndrome and (ii) patients with rotator cuff tears. Materials and Methods: We enrolled 43 patients with stage 1 or 2 impingement syndrome (group 1) and 21 patients with rotator cuff tears (group 2). The isokinetic strength of both groups was evaluated at $60^{\circ}/sec$ for external rotation, internal rotation, adduction and abduction. We measured the peak torque, total work, average power of bilateral sides, peak torque relationship to body weight, and the ratio between unilateral agonist and antagonist. Results: The isokinetic strength deficits assessed in ratio of peak torque to body weight for group 1 and group 2 respectively were; $28.48{\pm}23.76%$ and $29.12{\pm}32.81%$ for abduction (p=0.929), $7.20{\pm}13.98%$ and $18.94{\pm}19.52%$; for adduction (p=0.021), $16.88{\pm}13.76%$ and $25.80{\pm}24.07%$; for external rotation (p=0.221), and $14.1{\pm}25.67%$ and $29.02{\pm}35.06%$ for internal rotation (p=0.059). For average power and total work, group 2 showed a significantly greater deficit for adduction and internal rotation than group 1. Conclusion: Those with rotator cuff tears have more isokinetic muscle strength deficits than those with stage 1 or 2 impingement syndrome. Progression from stage 1 and 2 impingement syndrome to stage 3 may result in greatest changes in strength deficits for internal rotation and adduction.

The purpose of this study was to investigate the relationship between neck posture and range of motion and neck disability index(NDI) in young adults with reduced cervical lordosis. This study selected 34 young adults with cervical lordosis reduced (Cobb's angle less than 35 degrees). The assessor measured neck flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacements of all subjects using cervical of range motion instrument, Then, the NDI was evaluated. After all assessments, degree for cervical lordosis was divided into two groups: bottom group(severe cervical lordosis) and top group(mild cervical lordosis). The bottom group was significantly higher in Cobb's angle, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacement compared to the top group (p<.05). There was no significant difference between the two groups in flexion, NDI(p >.05). In comparison of subscale of NDI, top group was significantly higher in pain, lifting, and headache than bottom group (p <.05). In correlation analysis, Cobb's angle showed significant positive correlation with flexion, extension, left lateral flexion, right lateral flexion, left rotation and right rotation(p<.05), and showed significant negative correlation with forward displacement, NDI(p<.05). Cobb's angle showed a significant negative correlation with pain, lifting, and headache of subscale of NDI(p<.05). The findings of this study potentially suggest that neck posture may affect the cervical range of motion and pain.

Objective: The biomechanical stabilities between the anterior plate fixation after anterior discectomy and fusion (ACDFP) and the posterior transpedicular fixation after ACDF(ACDFTP) have not been compared using human cadaver in bilateral cervical facet dislocation. The purpose of this study is to compare the stability of ACDFP, a posterior wiring procedure after ACDFP(ACDFPW), and ACDFTP for treatment of bilateral cervical facet dislocation. Methods: Ten human spines (C3-T1) were tested in the following sequence: the intact state, after ACDFP(Group 1), ACDFPW(Group 2), and ACDFTP(Group 3). Intervertebral motions were measured by a video-based motion capture system. The range of motion(ROM) and neutral zone(NZ) were compared for each loading mode to a maximum of 2.0Nm. Results: ROMs for Group 1 were below that of the intact spine in all loading modes, with statistical significance in flexion and extension, but NZs were decreased in flexion and extension and slightly increased in bending and axial rotation without significances. Group 2 produced additional stability in axial rotation of ROM and in flexion of NZ than Group 1 with significance. Group 3 provided better stability than Group 1 in bending and axial rotation, and better stability than Group 2 in bending of both ROM and NZ. There was no significant difference in extension modes for the three Groups. Conclusion: ACDFTP(Group 3) demonstrates the most effective stabilization followed by ACDFPW(Group 2), and ACDFP(Group 1). ACDFP provides sufficient strength in most loading modes, ACDFP can provide an effective stabilization for bilateral cervical facet dislocation with a brace.

One of the Repeated survey which estimates variability of population, we can be consider rotation sample survey. There are two kinds of rotation sample survey - onelevel rotation sample survey and multi-level rotation sample survey. In rotation sample survey, Composite estimator is used to measure level or level change of the population. This study suggests Generalized Composite estimator as considering intraclass correlation in multi-level rotation sample survey, and optimal weight minimizing variance of estimator. Numerical example shows efficiency of Generalized Composite estimator as considering intraclass correlation according to the sample unit and change degree of intraclass correlation in the rotation group.

Objective: We aimed to investigate differences of range of motion in measuring shoulder internal rotation (IR) and external rotation (ER) resulting from posture change in manual scapular stabilization in prone, hook-lying, sitting, and standing positions in healthy young adults. Design: Cross-sectional study. Methods: This study included healthy young adults who agreed to participate after a thorough explanation about the study purpose and methods. A clinometer was used to measure shoulder rotation. Measurements of shoulder rotation according to postural change were performed in prone, hook-lying, sitting, and standing positions. The repeated measures analysis of variance was used to compare between-group differences in postural change. Results: The lower the posture, the greater the average value of IR angle. In contrast, the higher the posture, the greater the average value of the external rotation angle. In active and passive IR with posture change, there was difference in average value but with no statistical significance. In active and passive ER, there was a statistically significant difference between prone and sitting, prone and standing, hook-lying and sitting, hook-lying and standing, and sitting and standing position (p<0.05). Conclusions: Our findings suggest that postural change should be considered in order to increase the strength or range of motion of the internal and external rotation of the patient's shoulder joint.
