The effect of foot somatosensory loss in postural control during Functional reach test in patients with diabetic polyneuropathy: A controlled study.

BACKGROUND: In patients with diabetic polyneuropathy (DPN), differences in postural control due to losing the lower limb somatosensory information were reported. However, it is still unclear by which mechanisms the dynamic postural instability is caused. OBJECTIVES: This study aimed to investigate postural control differences and neuromuscular adaptations resulting from foot somatosensory loss due to DPN. METHODS: In this controlled cross-sectional study, fourteen DPN patients and fourteen healthy controls performed the Functional Reach Test (FRT) as a dynamic task. The postural control metrics were simultaneously measured using force plate, motion capture system, and surface electromyography (sEMG). The main metrics including reach length (FR), FR to height ratio (FR/H), displacement of CoM and CoP, moment arm (MA), and arch height ratio. Also, kinematic (range of motion of ankle, knee, and hip joints), and sEMG metrics (latencies and root mean square amplitudes of ankle and hallux muscles) were measured. To compare variables between groups, the independent sample T-test for (normally distributed) and the Mann-Whitney U test (non-normally distributed) were used. RESULTS: The subjects' reach length (FR), FR to height ratio, absolute MA, and displacement of CoM were significantly shorter than controls, while displacement of CoP was not significant. Arch height ratio was found significantly lower in DPN patients. We observed that CoM was lagging CoP in patients (MA = + 0.89) while leading in controls (MA = -1.60). Although, the muscles of patients showed significantly earlier activation, root mean square sEMG amplitudes were found similar. Also, DPN patients showed significantly less hip flexion, knee extension, and ankle plantar flexion. CONCLUSIONS: This study presented that decreasing range of motion at lower limbs' joints and deterioration in foot function caused poor performance at motor execution during FRT in DPN patients.

The Diagnostic Role of Adding the Hoffman Reflex for L5 Radiculopathy in the Electrodiagnostic Laboratory: A Cross-sectional Study.

OBJECTIVES: To investigate changes in the H-reflex in patients with monoradiculopathies involving L5 or S1 levels by stimulating the sciatic nerve and recording simultaneously from the tibialis anterior (TA), peroneus longus (PL), and soleus (S) muscles. METHODS: Patients with unilateral radicular back pain with L5 or S1 root compression on MRI, participated in this cross-sectional study. The H-reflex over the TA, PL, and S muscles was simultaneously recorded by sciatic nerve stimulation. The H-reflex latency was compared with that of the contralateral extremity. RESULTS: Fifty-eight patients (29 patients L5; 29 patients S1 radiculopathy) were included in the study. There were significant delays in the latency of the H-reflex over TA (30.95±2.31-29.21±1.4) and PL (31.05±2.85-29.02±1.99) muscles on the affected side in patients with L5 radiculopathy. However, the latency of the S H-reflex was similar on both sides. In contrast, in patients with S1 radiculopathy, there was a significant delay in the latency of soleus H reflex (32.76±3.45-29.9±3.19), while the significant delay was not detected in the TA and PL muscles. However, the cutoff values for the H-reflex latency of all muscles were not found to have clinical significance. CONCLUSIONS: The study presents that the H-reflex study, recorded from the TA, PL, and S muscles by sciatic nerve stimulation, is of interest but has minimal contribution to radiculopathy diagnosis in conventional electrodiagnostic tests.

Academic publication activities and perspectives of rheumatology practitioners in the COVID-19 pandemic.

Objectives: This study aimed to analyze the research, publication activities, and perspectives on clinical practices of rheumatology practitioners during the coronavirus disease 2019 (COVID-19) pandemic. Materials and methods: The survey-based cross-sectional study was designed online and included 24 closed-ended questions. After performing a pilot test and validation of survey, it was conducted among clinicians between September 2021 and December 2021. Results: One-hundred fifteen clinicians (54 males, 61 females; 78.1% in rheumatology practice for at least five years) responded to the survey. The respondents indicated that they worked in coronavirus-related departments, comprising inpatient service (50.4%), consultancy (42.6%), and outpatient clinic (27.8%). Around 40% of clinicians stated they spent less time on scientific research (43.1%) and clinical learning activities (43.2%), while almost the same proportion of them spent more (41.1% and 45.0%, respectively). This study revealed that 53.5% published at least one paper covering mostly COVID-19 in the scientific citation index (SCI) or SCI-expanded (SCI-E) indexed journals. However, nearly half of them did not have any papers published in the SCI/SCI-E (46.5%) or non-SCI/SCI-E indexed (44.6%) journals. Regarding the perspectives of clinicians about clinical practices, they considered fewer biological (57.0%) and nonbiological (55.0%) drug usage, reported fewer outpatient clinic visits (88.2%), more newly diagnosed rheumatic diseases (62.5%), and more disease exacerbations (31.2%). Most of the clinicians (range, 76.2 to 86.3%) thought they accurately managed their patients during the COVID-19 pandemic. Conclusion: Clinicians published mostly coronavirus-related papers in the pandemic era, and in the self-assessment, clinicians thought that they correctly manage their patients. In addition, this study reflected the frequency of academic publications and clinicians' work routines during the pandemic.

The role of ultrasonographic synovial assessment in rheumatoid arthritis patients with concomitant fibromyalgia.

Objectives: This study aimed to compare the prevalence and musculoskeletal ultrasonography (US) findings of rheumatoid arthritis (RA) patients with concomitant fibromyalgia (FM) according to the 1990 American College of Rheumatology (ACR) FM classification criteria or the 2016 ACR FM diagnostic criteria. Patients and methods: This cross-sectional study included 63 patients (17 males, 46 females; mean age: 48.2±7.1 years; range, 18 to 62 years) with RA. Medical history and laboratory data were obtained from electronic records. Clinical examination, composite disease activity measures, functional status, and the German 7-joint ultrasound score were assessed to evaluate disease activity and synovial inflammation. The patients were divided into three groups: patients who met only the 2016 ACR criteria, patients who met only the 1990 ACR criteria, and patients who met both criteria. Results: In patients with RA, concomitant FM prevalence was 34.9% according to the 2016 ACR FM diagnostic criteria versus 23.8% according to the 1990 ACR FM classification criteria. Rheumatoid arthritis patients with FM had high tender joint count and disease activity scores, while musculoskeletal US findings were similar. Patients who met only the 2016 ACR FM diagnostic criteria had significantly higher gray-scale US and power Doppler US synovitis scores than patients who satisfied only ACR 1990 FM classification criteria (p=0.03 and p=0.02, respectively). Conclusion: Synovial inflammation is a prominent sign in RA patients diagnosed with FM according to the 2016 ACR FM diagnostic criteria. The higher disease activity seen in the presence of FM in RA patients is associated with FM rather than synovitis.

The identification of association between ultrasonographic enthesitis and the ASAS Health Index in patients with axial spondyloarthritis.

This study aimed to evaluate association between the entheseal abnormalities in ultrasound and the Assessment of Spondyloarthritis International Society Health Index (ASAS HI) in patients with axial spondyloarthritis (axSpA). Seventy-four patients with axSpA were enrolled in this study. Ultrasonographic evaluation of entheses was performed by a blinded rheumatologist with the Madrid Sonographic Enthesitis Index (MASEI). The MASEI total score and the MASEI sub-scores (e.g., structural damage and activity scores) were calculated. The ASAS HI and the other SpA tools (e.g., Bath Ankylosing Spondylitis Disease Index, the Ankylosing Spondylitis Disease Activity Score) were used to evaluate patients' health and disease activity. Correlation and multivariate linear regression analyses were performed to assess the relationship between the MASEI and the ASAS HI. The mean score of the ASAS HI was 7.7 ± 4.6. The MASEI total score was calculated as 8.4 ± 6.8, while the mean MASEI-activity was 4.7 ± 3.6 and the mean MASEI-structural damage was 3.8 ± 4.5. There was no correlation between ASAS HI and MASEI total scores (r = 0.11, p = 0.34). However, the ASAS HI had a positive correlation with the MASEI-activity (r = 0.49, p < 0.001) and had a low negative correlation with the MASEI-structural damage (r = - 0.29, p < 0.05). In the linear regression model, the MASEI-activity and MASEI-structural damage were significantly related to the ASAS HI (ß = 0.72 and - 0.58, respectively; R2 = 0.53 p < 0.001). This study reported that the ASAS HI score was more negatively affected by active entheseal lesions rather than structural lesions. We suggest adding the entheses evaluation with ultrasonography to other tools for monitoring the health status of patients with axSpA.

The impact of the ongoing COVID-19 pandemic on the management of rheumatic disease: a national clinician-based survey.

This study aims to investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the management of rheumatic diseases (RD). An online survey included 10 questions were designed to assess potential differences in rheumatology practice. The survey was conducted between March 2021 and June 2021. Marginal homogeneity test was used to compare frequencies of outpatient clinic patients between the pre-pandemic and pandemic. Other results were analyzed by descriptive statistics. One hundred three clinicians (75.7% in rheumatology practice for at least five years) responded to the survey. Almost 70% examined < 30 patients per day during the pandemic while nearly 70% examined ≥ 30 patients per day before the pandemic (p < 0.001). They indicated following reasons for decreasing outpatient clinic activity were concerns regarding COVID-19 transmission risk of the patients (95%) and the clinicians (53%), being able to supply chronic medications directly from the pharmacy (85%), lockdown (71%), limited outpatient appointments (64%) and using telemedicine (20%). The frequencies of rheumatology daily routine procedures were decreased as follows; patient hospitalization for diagnosing (80%) and treatment (78%), labial salivary gland biopsy (63%), Schirmer's test/salivary flow rate test (56%), nail bed video-capillaroscopy (52%), musculoskeletal ultrasonography (51%) and Pathergy test (50%). Clinicians hesitated to use rituximab (63%) mostly, followed by cyclophosphamide (53%), glucocorticoids (43%), tofacitinib (41%), mycophenolate mofetil (36%), and azathioprine (33%). In this first national survey, the prominent differences in the management of RD have decreased outpatient clinic activity, reduced rheumatology daily procedures, and hesitancy to use some rheumatic drugs.

The Effect of Virtual Reality Exercises on Pain, Functionality, Cardiopulmonary Capacity, and Quality of Life in Fibromyalgia Syndrome: A Randomized Controlled Study.

Objective: To investigate the effect of motion-controlled videogames on pain, functionality, cardiopulmonary capacity, and quality of life in women with fibromyalgia. Materials and Methods: Forty women with fibromyalgia were randomized into virtual reality group (VRG) and conventional training group (CTG). The CTG performed aerobic exercise (cycling, 3 days per week, 20 minutes per day) and conventional exercises (muscle strengthening, balance, and flexibility, 3 days per week, 15 minutes per day) for 4 weeks. The VRG performed virtual reality exercise (volleyball, Microsoft Xbox Kinect®, 3 days per week, 15 minutes per day) together with cycling exercise for 4 weeks. After the exercise program, both groups received the same home exercise program for 4 weeks. All patients were evaluated at baseline, fourth, and eighth weeks. Primary outcome measure was Fibromyalgia Impact Questionnaire. Visual Analogue Scale (VAS), Hospital Anxiety and Depression Scale, Fatigue Severity Scale (FSS), Symptom Severity Scale, EuroQol-Five Dimensions Index Scale/Visual Analogue Scale (EQ-5D-index/VAS) and Six Minute Walk Test (6MWT) were used as secondary outcome measures. Results: Thirty-four patients (17 VRG, 17 CTG) were evaluated at the eighth week. After 4 weeks, all outcome measures improved significantly in both groups (P < 0.05). However, there was no statistically significant difference in all outcome measures between fourth and eighth weeks. Group and time interactions for 6MWT (P = 0.043), FSS (P = 0.026), EQ-5D-Index Scale (P = 0.014), and EQ-5D-VAS (P = 0.049) were significant only for the VRG. In addition, median individual's satisfaction was significantly higher in the VRG (P < 0.001). Conclusion: Virtual reality exercises along with aerobic exercise increase cardiopulmonary capacity and quality of life in fibromyalgia syndrome. In addition, they increase patient satisfaction and may improve patient compliance to exercise.
