Abstract
Background
Although balance impairment after hip fracture surgery (HFS) can constitute a long-term problem of limiting mobility and increasing the risk of falls in older adults, little is known about the effect of balance training (BT) on physical functioning after HFS. Thus, we performed a meta-analysis to evaluate whether BT improved the overall physical functioning of patients after HFS.
Methods
We searched the PubMed-Medline, Embase, and Cochrane Library databases in January 2018 and included all randomized controlled trials comparing BT with usual care after HFS. We performed a pairwise meta-analysis using fixed- and random-effects models.
Results
Eight randomized controlled trials including a total of 752 participants were retrieved. The BT group showed significantly improved overall physical functioning after HFS compared with the usual care group (overall standardized mean difference [SMD] = 0.390; 95% confidence interval [CI] = 0.114–0.667; p = .006). Both, balance and gait improved (SMD = 0.570; 95% CI = 0.149–0.992; p = .008 and SMD = 0.195; 95% CI = 0.043–0.347; p = .012, respectively) in the BT group. Lower limb strength, performance task, activity of daily living, and health-related quality of life also improved significantly in the BT group.
Conclusion
Our meta-analysis revealed that BT after HFS improved overall physical functioning. Positive effects on balance, gait, lower limb strength, performance task, activity of daily living, and health-related quality of life were evident. Therefore, BT should be specifically included in postoperative rehabilitation programs and balance must be thoroughly checked in elderly patients with hip fractures.

Abstract
OBJECTIVE To quantify the cross-sectional area (CSA) of lumbar dorsal root ganglion (DRG) by magnetic resonance imaging (MRI) and investigate the relationship between the cross-sectional area (CSA) of DRGs and sensory nerve action potentials (SNAP) amplitude in the lower extremities. METHODS Thirty-eight DRGs (20 L5 roots and 18 S1 roots) in 10 adult subjects were reviewed retrospectively. The CSA of the DRG was calculated from MR images of the coronal plane. SNAP amplitudes of the superficial peroneal nerve and sural nerve were corresponded to L5 and S1-DRGs. RESULTS The mean CSA of DRGs was 66.6 ± 13.7 mm2 in L5-DRG and 79.5 ± 14.3 mm2 in S1-DRG. The means of SNAP amplitudes were 19.6 ± 6.2 μV in superficial peroneal nerves and 24.6 ± 9.0 μV in sural nerves. In multivariate regression analysis, the CSA of DRGs had a significant correlation with SNAP amplitude. CONCLUSION The area of L5 and S1-DRGs may be positively correlated with SNAP amplitude.

Abstract
INTRODUCTION Although balance problems in older populations are directly correlated with hip fractures, the overall physical gain afforded by balance rehabilitation itself has not yet been fully investigated. Here we describe a protocol for an open-label clinical trial to evaluate the effectiveness of computer-based balance-specific exercise (BSE) on the performance and balance of elderly women who underwent hip fracture surgery (HFS). METHODS AND ANALYSIS Elderly female patients (≥65 years old) who underwent surgery for femoral neck, intertrochanteric, or subtrochanteric fracture regardless of surgery type will be included. The BSE will be conducted using a computed posturographic system for a 2-week intervention period following HFS. The primary outcome of this study is Berg balance scale score. All functional outcomes will be measured at 1 and 3 weeks and at 3 and 6 months after the surgical intervention. The data will be analyzed using the intention-to-treat principle.

Abstract
OBJECTIVE Although identification of factors that influence helmet use during bicycle riding is necessary for the selection of groups that require safe cycling education, limited baseline data are available. The aim of the present study was to analyze the rate of helmet use and the demographic factors that were independently associated with helmet use among Korean bicycle riders. METHODS In this cross-sectional study, we used public data from the Sixth Korean National Health and Nutrition Examination Survey conducted in 2013 and 2014. Helmet users were defined as subjects who always, usually, or frequently wore helmets when cycling. Independent factors associated with helmet use were determined using odds ratios (ORss) adjusted for 5 demographic factors via multivariate logistic regression analysis. RESULTS In the total population, 4,103 individuals were bicycle riders; among these, 782 individuals (19.1%) wore helmets. A total of 21.1% of male riders used helmets, compared to 15.5% of female riders (P <.001). The adjusted logistic regression model revealed that female sex (OR = 0.665; 95% confidence interval [CI], 0.554-0.797), teenage status (OR = 0.475, 95% CI, 0.333-0.678), and low household income (OR = 0.657, 95% CI 0.513-0.841) were significantly associated with nonuse of helmets. CONCLUSIONS Female sex, teenage status, and low household income were independent factors associated with the nonuse of helmets. We identified factors associated with helmet use during bicycle riding through analysis of baseline data on helmet usage.

Abstract
Cystic dilatation of synovial sheath, one of the targets of extra-hepatic manifestations associated with liver disease, is a main pathologic finding of lumbar synovial cyst (LSC). However, LSCs are not well documented in correlation with chronic viral hepatitis. In this case series, three patients with chronic viral hepatitis presented with radiating pain in the unilateral lower extremities. On magnetic resonance imaging of the lumbar spine, all had unilateral LSCs at the facet joint of the lumbar spine. Two did not have definite spinal instability at the LSC level. Ultimately, all three showed clinical improvements following epidural spine interventions.

Abstract
BACKGROUND Cognitive impairment is frequently seen in patients with stroke. The possible correlation between cognitive function and functional mobility has been proposed; however, the prognostic importance of early cognitive function in recovery of mobility has not been investigated in patients with stroke. OBJECTIVE The objective of this study is to investigate whether the cognitive function in the acute phase can independently predict the recovery of mobility after stroke, and to determine the cut-off value of each cognitive evaluation test for community ambulation at six months. METHODS Seventy two patients underwent four domain-specific neuropsychological evaluation tests at about two weeks after stroke; these included the word list memory test (WMT), construction praxis test (CPT), verbal fluency test (VFT) and Boston naming test (BNT). The Functional Ambulation Category (FAC) and ambulatory zone (AZ) at six months after stroke were investigated as outcome variables. The domain-specific cognitive function, along with other possible predictors for functional mobility, was analyzed with regression analysis. RESULTS The z-scores of WMT (p = 0.018) and VFT (p = 0.012) were related to the independence in ambulation. The z-scores of VFT (p = 0.006) and CPT (p = 0.009) were predictors for community ambulation, with the cut-off values of -2.215 for VFT, and of -0.845 for CPT. CONCLUSIONS Cognitive impairment in the acute phase of stroke can be an independent prognostic factor of functional mobility. Domain-specific neuropsychological evaluation tests should be considered in the acute phase of stroke to predict the recovery of functional mobility.

Abstract
BACKGROUND AND PURPOSE During stent-assisted coiling of ICA aneurysms, stent tips are sometimes unintentionally embedded into ICA branches. Stent tips can be visualized because they have radiopaque markers. Concerns regarding stent tip misplacement include risks of artery perforation and occlusion. The aim of this study was to evaluate the long-term outcomes of ICA branches with embedded stent tips. MATERIALS AND METHODS ICA branches with embedded stent tips were identified among 35 patients with unruptured ICA aneurysms treated with stent-assisted coiling between November 2003 and November 2014. Patient clinical and angiographic outcomes associated with the embedded stent tip were analyzed. RESULTS Most of the 35 studied aneurysms were paraclinoid ICA aneurysms (n = 30). The most commonly involved ICA branch was the posterior communicating artery (26 patients, 74.3%), followed by the anterior choroidal artery (8 patients, 22.9%) and ophthalmic artery (1 patient, 2.9%). During the follow-up period (38.6 ± 17.9 months), no new neurologic deficits developed. Neither hemorrhagic nor thromboembolic events occurred. Angiography was performed during the final follow-up evaluation at a mean of 32.7 ± 18.0 months, and all ICA branches with embedded stent tips showed patent blood flow without severe luminal narrowing. CONCLUSIONS In our experience, placement of a stent tip into ICA branches during stent-assisted coiling was not associated with any major adverse events.

Abstract
OBJECTIVES This study aimed to investigate the effects of three major representative exercises (resistance, flexibility, and walking) on quality of life (QoL) in a population of community-dwelling older adults. MATERIALS AND METHODS This cross-sectional study used public data from the Sixth Korean National Health and Nutrition Examination Survey in 2014 (n = 1,586 older people). Demographic factors, three types of exercise, five EuroQoL subsets (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and QoL scores (EQ-VAS) were investigated. The independent associations between each exercise and the five QoL subsets were determined using odds ratios (OR) adjusted for three demographic factors (age group, sex, and area of residence), using multivariate logistic regression analysis. RESULTS The EQ-VAS scores of the exercisers was significantly higher than those of the non-exercisers for all exercise types. Subjects with problems in mobility dimension performed less exercise of all types of than those with normal mobility (resistance: OR, 0.687; flexibility: OR, 0.733, and walking: OR, 0.489). The self-care dimension was independently correlated with flexibility (OR, 0.558) and walking (OR, 0.485). CONCLUSION All types of exercisers showed higher QoL scores than non-exercisers. Among the QoL dimensions, mobility and self-care were independently associated with flexibility and walking exercise in this older people, suggesting that engaging in regular flexibility and walking exercise is important for achieving higher QoL in the older people.

Abstract
Spasticity is an important factor in designing wearable and lightweight exoskeleton neurorehabilitation robots. The proposed study evaluates biomechanical reactions of an exoskeleton robot to spasticity and establishes relevant guidelines for robot design. A two-axis exoskeleton robot is used to evaluate a group of 20 patients post-stroke with spastic elbow and/or wrist joints. All subjects are given isokinetic movements at various angular velocities within the capable range of motion for both joints. The resistance torque and corresponding angular position at each joint are recorded continuously. Maximal resistance torques caused by low (modified Ashworth scale (MAS) 0, 1), intermediate (MAS 1+), and high (MAS 2 and 3) grade spasticity were 3.68 ± 2.42, 5.94 ± 2.55, and 8.25 ± 3.35 Nm for the elbow flexor ( , between each grades) and 4.23 ± 1.75, 5.68 ± 1.96, and 5.44 ± 2.02 Nm for the wrist flexor ( , for low versus intermediate, low versus high grade spasticity). The angular velocity did not significantly influence maximal resistance torque in either joint. The catch occurred more quickly at higher velocities for low and intermediate elbow flexor spasticity ( ). Spasticity caused considerable resistance to the robots during mechanically actuated movements. The resistance range according to the degree of spasticity should be considered when designing practical neurorehabilitation robots.

Abstract
Objective: To investigate a new botulinum neurotoxin type A, termed letibotulinumtoxinA(Botulax®) and compare its efficacy and safety for post-stroke upper limb spasticity with that of onabotulinumtoxinA(Botox®). Design: A prospective, double-blinded, multicenter, randomized controlled clinical study. Setting: Six university hospitals in Korea. Subjects: A total of 187 stroke participants with upper limb spasticity. Interventions: Two kinds of botulinum neurotoxin type A were used. One set of injection was performed and total injected doses were 309.21±62.48U(Botulax) and 312.64±49.99U(Botox)( P>0.05). Main measures: Primary outcome was measured using the modified Ashworth scale for wrist flexors at week 4 and secondary outcome was measured using modified Ashworth scale for wrist flexors, elbow flexors, finger flexors, and thumb flexors as well as Global Assessment in spasticity, Disability Assessment Scale, and Caregiver Burden Scale. Safety measures including adverse events, vital signs and physical examination, and laboratory tests were also monitored. Results: The mean ages for the Botulax group were 56.81±9.49 and which for the Botox group were 56.93±11.93( P>0.05). In primary outcome, the change in modified Ashworth scale for wrist flexors was -1.45±0.61 in the Botulax group and -1.40±0.57 in the Botox group, and the difference between the two groups was -0.06(95% CI:-0.23–0.12, P>0.05). In secondary outcome, both groups demonstrated significant improvements with respect to modified Ashworth scale, Global Assessment in spasticity, Disability Assessment Scale, and Caregiver Burden Scale ( P<0.05), and no significant difference was observed between the two groups ( P>0.05). In addition, safety measures showed no significant differences between the two groups ( P>0.05). Conclusions: The efficacy and safety of Botulax were comparable with those of Botox in treatment of post-stoke upper limb spasticity.

Park, JH, Seo, KS, and Lee, S-U. Effect of superimposed electromyostimulation on back extensor strengthening: a pilot study. J Strength Cond Res 30(9): 2470-2475, 2016-Electromyostimulation (EMS) superimposed on voluntary contraction (VC) can increase muscle strength. However, no study has examined the effect of superimposing EMS on back extensor strengthening. The purpose of this study was to determine the effect of superimposed EMS on back extensor strengthening in healthy adults. Twenty healthy men, 20-29 years of age, without low-back pain were recruited. In the EMS group, electrodes were attached to bilateral L2 and L4 paraspinal muscles. Stimulation intensity was set for maximally tolerable intensity. With VC, EMS was superimposed for 10 seconds followed by a 20-second rest period. The same protocol was used in the sham stimulation (SS) group, except that the stimulation intensity was set at the lowest intensity (5 mA). All subjects performed back extension exercise using a Swiss ball, with 10 repetitions per set, 2 sets each day, 5 times a week for 2 weeks. The primary outcome measure was the change in isokinetic strength of the back extensor using an isokinetic dynamometer. Additionally, endurance was measured using the Sorensen test. After 2 weeks of back extension exercise, the peak torque and endurance increased significantly in both groups (p ≤ 0.05). Effect size between the EMS group and the SS group was medium in strength and endurance. However, there was no statistically significant difference between 2 groups. In conclusion, 2 weeks of back extensor strengthening exercise was effective for strength and endurance. Superimposing EMS on back extensor strengthening exercise could provide an additional effect on increasing strength.

Abstract
BACKGROUND Sedentary lifestyle, a prevalent finding in modern society, can lead to weakness of the lumbar trunk musculature. Electrical stimulation (ES), in addition to lumbar strengthening exercises, has been shown to increase muscle strength. OBJECTIVE To assess the strengthening effect of ES on the lumbar paraspinal muscles during prolonged sitting. DESIGN Randomized, controlled, single-blind study. SETTING Tertiary hospital. PARTICIPANTS Thirty healthy subjects without low back pain. METHODS Thirty participants were randomly assigned to the ES group (n = 15) or the control group (n = 15). ES was administered over the lumbar paraspinal muscles, while subjects maintained a seated posture, at a maximal tolerable intensity for 60 minutes per day, three times per week, for 4 consecutive weeks. An identical protocol was used in the control group with muscle stimulation provided at the minimal sensory threshold intensity. MAIN OUTCOME MEASUREMENTS The isokinetic strength of the lumbar paraspinal muscles was evaluated at baseline, 4 weeks after the initiation of ES, and 8 weeks after the initiation of ES with an isokinetic dynamometer (Biodex Medical Dynamometer System-4) at 60°/s and 120°/s angular velocities. RESULTS The extension and flexion peak torque at 60°/s showed no significant interaction between the time and intervention or between the interventions. However, after 4 weeks of ES in the sitting position, the isokinetic extensor trunk muscle strength measured at 120°/s angular velocity significantly increased in the ES group (P < .05) compared with that in the control group. This effect was not maintained when measured at 4 weeks after the cessation of ES. CONCLUSIONS ES in a sitting position is a potentially effective and accessible rehabilitation treatment, which can lead to short-term improvement in the extensor trunk muscle strength of the lumbar paraspinal muscles.

Abstract
Objective To evaluate the feasibility of a new position (internal rotation in hanging) in ultrasonography, we compared the length of the glenohumeral joint space and the effectiveness of steroid injection with the hanging position and with the commonly used abdomen or cross position. Methods A prospective, randomized controlled trial was performed in 42 patients with adhesive capsulitis of shoulder. We used three arm positions for the posterior approach as follows: the patient's palm on thigh, other hand on abdomen (abdomen position); hand on patient's opposite shoulder (cross position); arm in hanging position with internal rotation of shoulder (hanging position). The order of shoulder position was randomized and blinded. Real-time ultrasonography-guided intra-articular steroid injection was performed by posterior approach at the first position in each patient. The Brief Pain Inventory (BPI), the Shoulder Pain and Disability Index (SPADI), and range of motion (ROM) were measured before steroid injection and 2 weeks after injection. Results The lengths of the joint space were 2.88±0.75, 2.93±0.89, and 2.82±0.79 mm in abdomen, cross, and hanging position respectively, with no significant difference among the three positions (p=0.429). Treatment efficacy was significantly improved in ROM, total BPI, and SPADI in all three positions (p<0.001). The changes in ROM for shoulder abduction were 23.6°±19.7°, 22.2°±20.9°, and 10.0°±7.8° in abdomen, cross, and hanging position, respectively. Changes in total BPI scores were 25.1±15.7, 23.6.±18.0, 11.6±6.1, and changes in total SPADI score were 35.0±14.2, 30.9±28.9, and 16.5±10.3 in abdomen, cross, and hanging position, respectively. There were no significant difference among the three positions for all parameters (p=0.194, p=0.121, and p=0.108, respectively. Conclusion For patients with adhesive capsulitis who cannot achieve or maintain abdomen or cross position, scanning and injection with the shoulder in internal rotation with hanging position may be a useful alternative.

Abstract
Objective To assess whether the cognitive function in the acute stage evaluated by domain-specific neuropsychological assessments would be an independent predictor of functional outcome after stroke. Methods Forty patients underwent 4 domain-specific neuropsychological examinations about 3 weeks after the onset of stroke. The tests included the Boston Naming Test (BNT), the construction recall test (CRT), the construction praxis test (CPT), and the verbal fluency test (VFT). The Korean version of Modified Barthel Index (K-MBI) at 3 months and the modified Rankin Scale (mRS) at 6 months were investigated as functional outcome after stroke. Functional improvement was assessed using the change in K-MBI during the first 3 months and subjects were dichotomized into 'good status' and 'poor status' according to mRS at 6 months. The domain-specific cognitive function along with other possible predictors for functional outcome was examined using regression analysis. Results The z-score of CPT (p=0.044) and CRT (p<0.001) were independent predictors for functional improvement measured by the change in K-MBI during the first 3 months after stroke. The z-score of CPT (p=0.049) and CRT (p=0.048) were also independent predictors of functional status at post-stroke 6 months assessed by mRS. Conclusion Impairment in visuospatial construction and memory within one month after stroke can be an independent prognostic factor of functional outcome. Domain-specific neuropsychological assessments could be considered in patients with stroke in the acute phase to predict long-term functional outcome.

Clinical Outcomes of Conservative Treatment and Arthroscopic Repair of Rotator Cuff Tears: A Retrospective Observational Study. Ann Rehabil Med 2016; 40:252-62. [PMID: 27152275 PMCID: PMC4855119 DOI: 10.5535/arm.2016.40.2.252] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2015] [Accepted: 08/14/2015] [Indexed: 01/15/2023] Open
Abstract
Objective To compare the clinical outcomes following conservative treatment and arthroscopic repair in patients with a rotator cuff tear. Methods In this retrospective study, patients aged >50 years with a symptomatic rotator cuff tear were reviewed. The rotator cuff tendons were evaluated using ultrasonography, shoulder magnetic resonance imaging or MR arthrography, and the patients with either a high-grade partial-thickness or small-to-medium-sized (≤3 cm) full-thickness tear were included in this study. The primary outcome measures were a pain assessment score and range of motion (ROM) at 1-year follow-up. The secondary outcomes were the rate of tear progression or retear along with the rate of symptom aggravation after the treatments. Results A total of 357 patients were enrolled, including 183 patients that received conservative treatment and 174 patients who received an arthroscopic repair. The pain assessment score (p<0.001) and the ROM in forward flexion (p<0.001) were significantly improved in both groups. The ROM in internal rotation did not significantly change after conservative treatment and arthroscopic repair. The pain assessment score and ROM were not significantly different between the two groups. Retear was observed in 9.6% of patients who had an arthroscopic repair and tear progression was found in 6.7% of those who underwent conservative treatment. The proportion of aggravation for pain and ROM did not significantly differ between the two groups. Conclusion The effectiveness of conservative treatment is not inferior to arthroscopic repair for patients >50 years old with a less than medium-sized rotator cuff tear in a 1-year follow-up period. Further study is warranted to find the optimal combination of conservative treatment for a symptomatic rotator cuff tear.

Abstract
UNLABELLED To investigate (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) signal changes of denervated muscles in patients with electrophysiologically confirmed neuropathy. METHODS This is a case series of three cancer patients who were referred to the electromyography laboratory in 2013 due to shoulder discomfort after surgery including neck dissection. Spinal accessory neuropathy was diagnosed based on electrophysiological studies. Patients' medical history, electrophysiological data, and FDG-PET images were reviewed retrospectively. Mean standard uptake values (SUV) of trapezius muscles were measured. RESULTS The patients (3 men, aged 61-78years) showed spinal accessory neuropathy with different degrees of severity. In all patients, preoperative or postoperative FDG-PET showed increased FDG uptake in the ipsilateral trapezius muscle. These results were compatible with previously reported glucose hypermetabolism in denervated skeletal muscles. CONCLUSION This is the first clinical report of increased FDG uptake by denervated muscles in electrophysiologically confirmed neuropathy.

Abstract
BACKGROUND The association between fatty replacement of rotator cuff and hemiplegic upper extremity function has not been defined yet. Moreover, the relationships among rotator cuff tears, shoulder pain, spasticity, and fatty replacement were not clearly studied. OBJECTIVE We investigated the association of fatty replacement of the supraspinatus and infraspinatus muscles with tendon tear in stroke or brain-injured patients. METHODS A total of 72 hemiplegic patients were enrolled in 3 hospitals, and ultrasonography of both shoulders was performed once. Fatty replacement of the supraspinatus and infraspinatus was graded by the visibility of outer contours, pennate pattern, central tendon, and echogenicity. RESULTS Fatty replacement was observed in 22 (30.6%) out of the 72 patients (in 18 supraspinatus muscles and 12 infraspinatus). Inter-rater agreement (kappa value) between the 2 physiatrists was 0.530 for the supraspinatus, and 0.411 for the infraspinatus. The Fugl-Meyer assessment score, Brunnstrom stage, and modified Barthel index were significantly lower in patients with fatty replacement of the supraspinatus or infraspinatus (group 1) than in those without (group 2). The motor power of both shoulders, the pain-free range of motion, spasticity, and hemiplegic shoulder pain were comparable between the two groups. The tear rate of the supraspinatus, infraspinatus, or subscapularis tendon at the hemiplegic side was higher than that at the contralesional side in each group, although there was no significant difference between group 1 and group 2. CONCLUSION Disuse leading to muscle atrophy rather than rotator cuff tear might be the cause of fatty replacement of these muscles, which may be associated with decreased function of the hemiplegic upper extremities.

Abstract
Botulinum toxin A is widely used in the clinics to reduce spasticity and improve upper limb function for post-stroke patients. Efficacy and safety of a new botulinum toxin type A, NABOTA (DWP450) in post-stroke upper limb spasticity was evaluated in comparison with Botox (onabotulinum toxin A). A total of 197 patients with post-stroke upper limb spasticity were included in this study and randomly assigned to NABOTA group (n=99) or Botox group (n=98). Wrist flexors with modified Ashworth Scale (MAS) grade 2 or greater, and elbow flexors, thumb flexors and finger flexors with MAS 1 or greater were injected with either drug. The primary outcome was the change of wrist flexor MAS between baseline and 4weeks post-injection. MAS of each injected muscle, Disability Assessment Scale (DAS), and Caregiver Burden Scale were also assessed at baseline and 4, 8, and 12weeks after the injection. Global Assessment Scale (GAS) was evaluated on the last visit at 12weeks. The change of MAS for wrist flexor between baseline and 4weeks post-injection was -1.44±0.72 in the NABOTA group and -1.46±0.77 in the Botox group. The difference of change between both groups was 0.0129 (95% confidence interval -0.2062-0.2319), within the non-inferiority margin of 0.45. Both groups showed significant improvements regarding MAS of all injected muscles, DAS, and Caregiver Burden Scale at all follow-up periods. There were no significant differences in all secondary outcome measures between the two groups. NABOTA demonstrated non-inferior efficacy and safety for improving upper limb spasticity in stroke patients compared to Botox.

Abstract
Avulsion fracture of the acromion is rare. It is difficult to diagnosis because there is little displacement and it occurs even without direct trauma. We experienced a case without direct trauma that was diagnosed with ultrasonography. A 55-year-old male patient visited our outpatient clinic with shoulder pain resulting from a significant stress at the trapezius muscle during lifting of a steel reinforcement. Simple radiography revealed a calcific deposit over the acromion rather than a fracture. Avulsion fracture was identified with ultrasonography. This is the first report demonstrating that ultrasonography has an advantage over radiographs in the diagnosis of an avulsion fracture of the acromion of the scapula.

Abstract
UNLABELLED The purpose of this study was to confirm glucose hypermetabolism in denervated muscle and investigate the feasibility of (18)F-FDG PET scanning for the detection of muscle denervation. METHOD A sciatic neuropathy model in rats was created by nerve resection of the left sciatic nerve and sham operation on the other side. Eight days after denervation, small-animal PET/CT scans of the hindlimbs were acquired. Muscle denervation was confirmed by electrophysiologic and histologic study. RESULTS All rats showed increased (18)F-FDG uptake in the muscles of the left (denervated) lower legs. The calculated maximum lesion-to-normal counts ratio of the left lower leg anterolateral (left, 11.02 ± 2.08; right, 1.81 ± 0.40, n = 6, P < 0.01) and posterior (left, 9.81 ± 4.58; right, 1.87 ± 0.44, n = 6, P < 0.01) compartment were significantly increased. The electrophysiologic and histologic study verified muscle denervation. CONCLUSION Glucose hypermetabolism in muscle denervation is an obvious phenomenon. (18)F-FDG PET scanning can be used to visualize muscle denervation.

Additional effects of transcranial direct-current stimulation and trigger-point injection for treatment of myofascial pain syndrome: a pilot study with randomized, single-blinded trial. J Altern Complement Med 2014; 20:698-704.

Abstract
BACKGROUND Chronic pain caused by myofascial pain syndrome (MPS) results in generalized and debilitating conditions. Trigger-point injection (TPI) is the mainstay of MPS management to reduce acute and localized pain. Other adjunctive intervention to modulate the central pain pathway might be helpful if they are combined with TPI. Transcranial direct-current stimulation (tDCS), which is a form of neurostimulation, has been reported to be safe and effective in treating chronic pain by changing cortical excitability. OBJECTIVES To determine whether there is an additional effect of tDCS and TPI to reduce pain in patients with MPS. PATIENTS Twenty-one patients with newly diagnosed MPS of shoulder girdle muscles. INTERVENTIONS Patients were randomly assigned into 1 of 3 groups (2 active and 1 sham stimulation groups) and received TPI. Immediately after TPI, tDCS (2 mA for 20 minutes on 5 consecutive days) was administered. For the active stimulation groups, tDCS was applied over 2 different locations (primary motor cortex and dorsolateral prefrontal cortex [DLPFC]). OUTCOME MEASURES Visual analogue scale (VAS), Pain Threshold Test, and short form of the McGill Pain Questionnaire were measured before and immediately after stimulation for 5 consecutive days. RESULTS The mean VAS values were decreased in all three groups after 5 days. There was a significant change between before and after stimulation only in the DLPFC group. The significant change in the mean VAS value was shown from after the second stimulation session (p=0.031), and this remained significant until the last stimulation session (p=0.027). CONCLUSION This study suggests that tDCS over DLPFC may have additional effects with TPI to reduce pain in patients with MPS. tDCS over DLPFC can be used to reverse central pain pathway by modulating cortical plasticity.

Abstract
Objective To assess whether the order of test diets influences the results of swallowing studies with regard to their accuracy and safety. Methods Subjects with suspected dysphagia underwent a videofluoroscopic swallowing study (VFSS) and/or a fiberoptic endoscopic evaluation of swallowing (FEES) and repeated the study on the same day or within a week. The order of test diets comprised of two different sets: trial 1 with the fluid first and trial 2 with the semi-solid food first. Main outcome measurements were the modified penetration-aspiration scale (mPAS) and the pharyngeal residue severity scale (PRSS) for the vallecula and the pyriform sinus. Results Sixty-six patients (44 men and 22 women, aged 65.0±15.0 years) were enrolled in this study. Forty-three subjects were evaluated with VFSS only and 23 with both VFSS and FEES. As a result of the swallowing studies, there was no significant difference in each chosen diet sequence regarding mPAS and PRSS. Furthermore, there was no difference regarding the duration of studies, rate of premature study termination, rate of abnormal findings in post-study chest X-ray, and rate of fever or pneumonia post-study. Conclusion The accuracy and safety of the swallowing studies do not rely on the order of test diets.

Abstract
Objective To compare fluid thickeners composed of starch polysaccharide (STA), guar gum-based polysaccharide (GUA), and xanthan gum-based polysaccharide (XAN) with the use of a viscometer and a line spread test (LST) under various measurement conditions. Methods The viscosity of thickened fluid with various concentrations (range, GUA 1%-4%, XAN 1%-6%, STA 1%-7%, at intervals of 1%) was measured with a rotational viscometer with various shear rates (1.29 s-1, 5.16 s-1, 51.6 s-1, and 103 s-1) at a temperature of 35℃, representing body temperature. The viscosity of STA showed time dependent alteration. So STA was excluded. Viscosities of GUA and XAN (range of concentration, GUA 1%-3%, XAN 1%-6%, at intervals of 1%) were measured at a room temperature of 20℃. LST was conducted to compare GUA and XAN (concentration, 1.5%, 2.0%, and 3.0%) at temperatures of 20℃ and 35℃. Results The viscosities of 1% GUA and XAN were similar. However, viscosity differences between GUA and XAN were gradually larger as concentration increased. The shear thinning effect, the inverse relationship between the viscosity and the shear rate, was more predominant in XAN than in GUA. The results of LST were not substantially different from GUA and XAN, in spite of the difference in viscosity. However manufacturers' instructions do not demonstrate the rheological properties of thickeners. Conclusion The viscosities of thickened fluid were different when the measurement conditions changed. Any single measurement might not be sufficient to determine comparable viscosity with different thickeners. Clinical decision for the use of a specific thickener seems to necessitate cautious consideration of results from a viscometer, LST, and an expert's opinion.
