Purpose : This study was to identify the effects of Mobilization with Movement combined with exercise (EMWM) on acromio-humeral distance (AHD), range of motion (ROM), pain intensity, and functional performance in patients with impingement syndrome of the shoulder. Methods : The subjects were 40 patients diagnosed with impingement syndrome of the shoulder. Twenty subjects are randomly assigned to each 2 different groups; Group 1. (exercise group), Group 2. (EMWM group). Three weekly interventions were given for 4 weeks. The main outcome measures were ultrasound, goniometer, visual analogue scale (VAS), and Korean Constant shoulder score (K-CSS). The ultrasound (AHD), ROM (flexion, abduction), pain intensity (for shoulder flexion) and functional performance (K-CSS) were compared between the groups. Results : The AHD was significantly increased in Group 2 compared to Groups 1. No significant difference was observed between the groups in the range of abduction of the shoulder, but the range of flexion was significantly increased in Group 2 compared to Groups 1. Pain intensity was significantly lower in Group 2 than in Group 1, and functional performance was significantly increased in Group 2 compared to Group 1. Conclusion : An intervention that combined mobilization with movement with exercise was more effective than exercise alone for rapid recovery from shoulder injury and improvement in functional performance.

Purpose : This study was to investigate the effectiveness of ESWT and plantar fascia-specific stretching exercise vs ESWT and high-load strengthening exercise in patients with chronic plantar fasciitis. Methods : The subjects were randomized to extracorporeal shock wave therapy ( ESWT, for 3 weeks) and daily plantar-specific stretching (Group I: Stretch group) or ESWT and high-load progressive strength (Group II: Strength group) performed every second day. The main outcome measures were ultrasound, visual analogue scale (VAS), and Korean Foot Function Index (KFFI). The ultrasound (plantar fascia thickness), pain intensity I, II (the most painful of the day?, the pain when you first step in the morning?) and KFFI (functional performance) were compared between the groups. Results : No significant difference was observed between the groups in the plantar fascia thickness but pain intensity I, II was significantly lower in Group 2 than in Group 1 at only 12weeks and functional performance was also significantly increased in Group 2 compared to Group 1 at only 12 weeks. Conclusion : The high-load strengthening exercise consisting of the progressive exercise protocol, resulted in superior after 12 weeks compared with plantar-specific stretching. High-load strength exercise may aid in a quicker reduction in pain and improvements in functional performance.

Background: Evaluation of the effectiveness of caudal epidural injection on pain, spine mobility, disease activity, and activity of daily living in axial spondyloarthritis (SpA) patients. Methods: A total sample of 47 patients were registered in this study. They were randomly assigned into 2 groups; Group I received caudal epidural injections, ultrasound-guided, with 1% lidocaine hydrochloride mixed with triamcinolone, whereas Group II did not receive any injections. All participants fulfilled the ASAS criteria for axial SpA. Outcome measures were as follows: visual analogue scale, Oswestry disability index (ODI), modified Schober test, lateral lumbar flexion, and Ankylosing Spondylitis Disease Activity Score (ASDAS) with assessment at baseline, 2 weeks, and 8 weeks post-treatment. This clinical trial was registered on clinicaltrials.gov under the number NCT04143165. Results: There was a significant difference between both groups regarding pain, ODI, spine mobility and ASDAS scores in favor of group I. This effect was at its maximum after 2 weeks. Despite the decline of this effect after 2 months, the difference between the groups remained significant. Higher disease activity, younger age, and shorter disease duration were associated with better outcomes. Conclusions: Epidural injection of lidocaine and triamcinolone is a cost effective and a practical technique for controlling pain, as well as improving the function of the spine and disease activity scores in axial SpA patients with acceptable complications and relatively sustained effect.

Objective: This study aimed to investigate the reliability and validity of a personal computer-based muscle viewer (PC-BMW) compared with that of a portable ultrasound (P-US) for measuring upper trapezius (UT) and transversus abdominis (TrA) muscle thickness at rest and during contraction. Design: Observational inter-rater reliability study. Methods: Fifty-five healthy participants (25 men, 30 women) participated in this study. PC-BMW and P-US were randomly measured at the UT and TrA muscles. Two examiners randomly obtained the images of all participants in 3 test sessions lasting 2 days. Intra-class correlation coefficients (ICCs), standard error of measurement, contraction ratio, and correlation were used to estimate reliability and validity. Pearson's correlation coefficients were used to analyze the relationship between muscle thickness measures taken from PC-BMW and P-US. Results: The intra-rater reliability ICCs of UT and TrA muscle thickness for the PC-BMW were >0.995, indicating excellent reliability. Inter-rater reliability ICCs for the PC-BMW ranged from 0.963 to 0.987. The P-US also exhibited high reliability. A high correlation was found between the measurements of the two muscles in PC-BMW and P-US (p<0.01). Conclusions: PC-BMW provides clear and excellent images, is pocket-sized and less expensive than a conventional ultrasound imaging system. PC-BMW can be utilized variously and has the advantage of rehabilitative ultrasound imaging. More research is needed to evaluate the utility of PC-BMW for rehabilitation.

Objective: Rehabilitative ultrasound imaging is a safe and noninvasive technique for evaluating muscle thickness. A dual probe-fixing frame (DPF) can provide visual feedback during exercises targeting specific muscles. The purpose of this research was to verify the reliability and validity of the DPF for dual-probe ultrasound (DPU)-based visual feedback exercises, allowing users to use both hands freely. Design: This cross-sectional study used repeated measures to compare muscle thickness measurements obtained using the handheld device and DPF with DPU. Methods: Twenty healthy adults participated in the study. Measurements were taken over two sessions, with a two-day interval between the sessions. The thicknesses of the rectus abdominis (RA) and transverse abdominis (TrA) muscles were measured using DPU. The DPF with DPU developed by the research team, was used along with a laptop-based muscle viewer. Bland-Altman analysis and intraclass correlation coefficients (ICCs) calculations were used in statistical analyses to evaluate agreement and reliability, respectively. Results: The results of the Bland-Altman analysis showed small average differences between the handheld and DPF methods for both RA and TrA muscle thicknesses. Inter-rater reliability analysis showed high ICC values for DPF measurements of both RA (0.908-0.912) and TrA (0.892-741) muscle thicknesses. Intra-rater reliability analysis also showed good ICC values for measurements taken by a single examiner over two days. Conclusion: The findings of this study demonstrate that the DPF provides reliable and valid measurements of muscle thickness during visual feedback exercises using the DPU.

Objectives This study aims to comprehensively review research utilizing ultrasonography for assessing manipulative treatment on spinal diseases, with the goal of promoting the wider integration of ultrasound imaging into clinical practice. Methods A systematic search was conducted on three international databases (Embase, PubMed, Cochrane) up to July 23, 2023. The search included key terms such as ultrasonography, manipulation, and skeletal muscle. The inclusion criteria narrowed down the selection to studies specifically related to lumbar and cervical vertebrae. Results Eleven studies were included in the review, with 10 focusing on lumbar vertebrae and one on cervical vertebrae, all employing spinal manipulation treatment. Among the 11 selected studies, nine primarily focused on ultrasound imaging to measure muscle thickness, while two utilized shear wave elastography to assess muscle stiffness. Also, rigorous measures were taken to ensure the reliability of the ultrasonography data. Conclusions This scoping review highlights the limited but growing evidence supporting the use of ultrasonography to assess manipulative treatment for spinal diseases. Despite a scarcity of studies in South Korea, it is crucial to recognize the potential of ultrasonography in becoming a widely used and practical tool for evaluating the effectiveness of manipulative treatments in the near future.

피부를 통한 약물 전달 방법은 국소 병변 부에 직접적으로 약물을 전달할 수 있는 장점을 가졌으나 피부의 가장 바깥 층인 각질층의 장벽기능으로 인해 약물 전달 능력에 제한이 있다. 본 연구에서는 산소 압력 방법과 초음파 방법을 결합하는 방법을 시도하여 약물 전달 능력의 향상 정도를 검증해 본다. 흡수 물질로는 수분을 사용하였고 수분의 흡수도를 측정하기 위해 피부 임피던스 방법을 선택하였다. 실험은 총 42명을 대상으로 각각 대조군(13명) 초음파군(13명), 산소 압력군(6명). 초음파와 산소압력 결합군(10명)으로 나누어서 시행하였다. 각 군마다 다른 약물 전달방법을 손등 부위에 적용하여 20분간 피부 임피던스 변화를 측정 한 값을 PC에 저장하였다. 수분을 적용한 대조군의 경우 피부 임피던스의 변화가 거의 일어나지 않고. 초음파를 적용한 군과 산소를 적용한 군은 수분을 적용한 군보다 25-30배정도 높은 수분 홉수를 보였으며. 초음파와 산소 압력을 결합한 방법은 수분을 적용한 군보다 70배정도 높은 수분 흡수를 보였다. 이러한 평균의 타이를 반복 측정된 분산방법(Repeated Measures Analysis of Variance)의 다변량 검증과 다중비교를 통해 변화량간의 차이를 검증하여 유의성을 확인하였다

Background: The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O₂-O₃) injection in patients with chronic supraspinatus tendinopathy. Methods: Participants were randomly assigned to the corticosteroid group (n = 22) or ozone group (n = 22). Injections in both groups were administered into subacromial bursa with an US-guided in-plane posterolateral approach. Primary outcome measure was the change in the Western Ontario Rotator Cuff Index (WORC) score between baseline and 12-weeks post-injection. Secondary outcome measures included visual analog scale and Shoulder Pain and Disability Index scores. Assessments were recorded at baseline, and 4-weeks and 12-weeks post-injection. Results: Forty participants completed this study. Based on repeated measurement analysis of variance, a significant effect of time was found for all outcome measures in both groups. Both the groups showed clinically significant improvements in shoulder pain, quality of life, and function. Baseline, 4-week post-injection, and 12-week post-injection WORC scores (mean ± standard deviation) were 57.91 ± 18.97, 39.10 ± 20.50 and 37.22 ± 27.31 in the corticosteroid group, respectively and 69.03 ± 15.89, 39.11 ± 24.36, and 32.26 ± 24.58 in the ozone group, respectively. However, no significant group × time interaction was identified regarding all outcome measures. Conclusions: Three-time ozone injection was not superior to a one-time corticosteroid injection in patients with chronic supraspinatus tendinopathy. It might be as effective as corticosteroid injection at 4-weeks and 12-weeks post-injection in terms of relieving pain and improving quality of life and function.

The lower trapezius muscle is an important stabilizer and primary mover of the scapula. The potential use of ultrasound imaging to evaluate scapular muscle function warrants investigation. The purpose of this study is to use ultrasound imaging for determining the effectiveness of 4 different isometric exercises for maximally activating the lower trapezius muscles in healthy subjects. Twenty-eight (14 men and 14 women) volunteers were recruited for this study. Thickness measurements of the lower trapezius muscles were recorded during 4 exercises: latissimus pulldown (LP), prone V-raise (PV), prone row (PR), and modified prone cobra (MP). Lower trapezius muscle thickness was measured 3 times by 2 investigators at a point 3 cm lateral to the lateral edge of the T8 spinous process. The order of 4 exercise execution was randomized for each participant. To identify statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. Intraclass correlation coefficient (ICC) for intra-reliability was .86~.98 and inter-rater reliability .83~.96 for the lower trapezius, respectively (p<.01). Thickness changes in the lower trapezius muscles between the relaxed and contracted states in men were as follows: LP ($7.37{\pm}2.68mm$, 182%), MP ($4.69{\pm}1.74mm$, 167%), PV ($4.52{\pm}1.47mm$, 149%), and PR ($3.84{\pm}1.72mm$, 133%). In women the values were as follows: LP ($4.64{\pm}1.24mm$, 163%), MP ($2.79{\pm}.81mm$, 131%), PV ($2.78{\pm}.85mm$, 129%), and PR ($2.21{\pm}1.26$ mm, 100%). Thickness of the lower trapezius muscles significantly differed between exercises in both the gender (p<.01). The LP was the most effective exercise for increasing the activation of the lower trapezius muscle in both the gender. We recommend performing the LP exercise for strengthening the lower trapezius muscles.

현재 한우 후보씨수소는 당대검정을 거쳐 12개월령 체중의 육종가와 근내지방도의 혈통지수를 근거로 선발이 이뤄진다. 여기서 이용되는 혈통지수는 실제 검정을 통하여 얻은 능력이 아니라 혈통과 KPN의 능력을 근거로 산출한 능력으로써 정확도가 그리 높지 않다. 그리고 후보씨수소에 대한 후대검정은 현재 검정소 검정과 현장 후대검정으로 나뉘어져 있다. 현장 후대검정의 경우 24개월령 도축이 어렵기 때문에 검정소와 현장 후대검정우를 동시에 비교하기는 쉽지 않다. 따라서 본 연구는 이와 같이 12개월령에 측정이 불가한 선발형질과 현장 후대검정우와 검정소 검정우의 도축시기의 차이를 해소하기 위하여 초음파 측정 기술을 적용하여 도체형질 유전능력을 간접적으로 평가 가능한지 파악하기 위하여 수행 하였다. 연구수행을 위하여 2008년도부터 2013년까지 농협중앙회 한우개량사업소 및 한우육종농가에서 수집한 한우 당 후대검정 자료를 이용하였으며 분석형질로는 12개월령 체중, 12 24개월령 초음파 형질(등심단면적, 등지방두께, 둔부지방, %지방함량) 및 도체형질(도체중, 등심단면적, 등지방두께, 근내지방도)을 이용하였다. 초음파 형질에 대한 환경효과 분석을 통하여 차수-측정일-우사-촬영자-판독자를 동기우군으로 하고 측정 시 체중을 공변량으로 한 모형을 토대로 유전모수를 추정하였다. 그 결과 12개월령 및 24개월령 초음파 형질들에 대한 유전력은 각각 0.21-0.43, 0.32-0.47이었으며 12 24개월령 초음파 형질과 대응되는 도체형질이 각각 0.52-0.75, 0.86-0.89로 높은 유전상관을 보이는 것으로 나타났다.
