MRI and Ultrasound Analysis of Corticosteroid Injection Combined with Extracorporeal Shockwave Therapy in Lateral Epicondylitis-A Prospective, Randomized, Double-Blinded, Placebo-Controlled Trial.

OBJECTIVE: The knowledge about the effective implementation of corticosteroid injection and extracorporeal shockwave therapy on radiological changes in chronic lateral epicondylitis is lacking. Therefore, the objective of this study is to find and compare the effects of corticosteroid injection and extracorporeal shockwave therapy on radiological changes in chronic lateral epicondylitis. METHODS: A randomized, double-blinded controlled study was conducted on 60 LE participants at a university hospital. The active extracorporeal shockwave therapy group (n = 30) received a corticosteroid injection with active extracorporeal shockwave therapy one session a week for 4 weeks, and the placebo extracorporeal shockwave therapy group received a corticosteroid injection with placebo extracorporeal shockwave therapy. The primary outcome was pain intensity, measured with the visual analog scale. The other outcome measures were the percentage of injury measured by magnetic resonance imaging and ultrasound, functional disability, handgrip strength, patient perception, kinesiophobia, depression status, and quality of life. RESULTS: The between-group difference in pain intensity at 4 weeks was 1.4 (CI 95% 0.77 to 2.02), which shows more improvement in the active group than in the placebo group. Improvements in the effects were noted after 8 weeks and at 6 months (1.8; CI 95% 1.50 to 2.09) follow-up. Similar improvements were also found in the percentage of injury, functional disability, handgrip strength, patient perception, kinesiophobia, depression status, and quality of life. CONCLUSION: Extracorporeal shockwave therapy has added effects on corticosteroid injection for improving pain, percentage of injury, functional disability, handgrip strength, patient perception, kinesiophobia, depression status and quality of life in people with chronic lateral epicondylitis.

Effect of Transcranial Direct Current Stimulation Augmented with Motor Imagery and Upper-Limb Functional Training for Upper-Limb Stroke Rehabilitation: A Prospective Randomized Controlled Trial.

BACKGROUND: Combining transcranial direct current stimulation (tDCS) with other therapies is reported to produce promising results in patients with stroke. The purpose of the study was to determine the effect of combining tDCS with motor imagery (MI) and upper-limb functional training for upper-limb rehabilitation among patients with chronic stroke. METHODS: A single-center, prospective, randomized controlled trial was conducted among 64 patients with chronic stroke. The control group received sham tDCS with MI, while the experimental group received real tDCS with MI. Both groups performed five different upper-limb functional training exercises coupled with tDCS for 30 min, five times per week for two weeks. Fugl-Meyer's scale (FMA) and the Action Research Arm Test (ARAT) were used to measure the outcome measures at baseline and after the completion of the 10th session. RESULTS: Analysis of covariance showed significant improvements in the post-test mean scores for FMA (F (414.4) = 35.79, p < 0.001; η2 = 0.37) and ARAT (F (440.09) = 37.46, p < 0.001; η2 = 0.38) in the experimental group compared to the control group while controlling for baseline scores. CONCLUSIONS: Anodal tDCS stimulation over the affected primary motor cortex coupled with MI and upper-limb functional training reduces impairment and disability of the upper limbs among patients with chronic stroke.

A Systematic Review of Psychometric Properties of Knee-Related Outcome Measures Translated, Cross-Culturally Adapted, and Validated in Arabic Language.

During the previous two decades, patient-reported outcome measures (PROMs) have been well tested, and the tools were validated in different languages across the globe. This systematic review aimed to identify the knee disease-specific outcome tools in Arabic and evaluate their methodological quality of psychometric properties of the most promising tools based on the COSMIN checklist and PRISMA guidelines. Articles published in English, from the inception of databases until the date of search (10 August 2022), were included. Articles without at least one psychometric property (reliability, validity, and responsiveness) evaluation, and articles other than in the English language, were excluded from the study. The key terms ["Arabic" AND "Knee" AND ("Questionnaire" OR "Scale")] were used in three databases, i.e., PubMed, Scopus, and Web of Science (WoS) in the advanced search strategy. Key terms were either in the title or abstract for PubMed. Key words were in the topic (TS) for WoS. COSMIN (COnsensus-based Standards for the selection of health Measurement Instruments) risk of bias checklist was used to evaluate the methodological quality of psychometric properties of the Arabic knee-related outcome measures. A total of 99 articles were identified in PubMed, SCOPUS, and WoS. After passing inclusion and exclusion criteria, 20 articles describing 22 scales from five countries were included in this review. The instruments validated in the Arabic language are Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee injury and osteoarthritis outcome score (KOOS), knee outcome survey- activities of daily living scale (KOS-ADLS), Oxford knee score (OKS), anterior knee pain scale, osteoarthritis of knee and hip health-related quality of life (OAKHQoL) scale, Lysholm knee score (LKS), international documentation committee subjective knee form (IKDC), intermittent and constant osteoarthritis pain (ICOAP) questionnaire, Kujala patellofemoral pain scoring system (PFPSS), anterior knee pain scale (AKPS) and osteoarthritis quality of life questionnaire (OAQoL),. All were found to have good test-retest reliability (Intra Correlation Coefficient), internal consistency (Cronbach's alpha), and construct validity (Visual Analog Scale, Short Form-12, RAND-36, etc.). Of 20 instruments available to assess self-reported knee symptoms and function, 12 were validated in the Saudi Arabian population. Among them, KOS-ADLS is the best PROM to be used in various knee conditions, followed by KOOS and WOMAC. The assessed methodological quality of evidence says that the knee Arabic PROMs are reliable instruments to evaluate knee symptoms/function.
