Ultrasound-Guided Pes Anserine Bursitis Injection Choices: Prolotherapy or Oxygen-Ozone or Corticosteroid: A Randomized Multicenter Clinical Trial.

OBJECTIVE: Pes anserine bursitis is the most common cause of periarticular knee pain. The aim of the study was to evaluate the efficacy of local injection-based therapies with different materials. DESIGN: The enrolled patients were randomly allocated to three groups to receive different interventions. Outcome measures included pain severity using the visual analog scale and the Western Ontario and McMaster Universities osteoarthritis index that was evaluated before the intervention, 1 and 8 wks after that. RESULTS: This trial was performed on 72 participants, with male-to-female ratio of 0.14 and with a mean age of 61.49 ± 9.35 yrs. Corticosteroids in the first group, oxygen-ozone in the second group, and dextrose 20% in the third group, were injected into the pes anserine bursa under ultrasound guidance. Interaction between time and group showed a statistically significant improvement in visual analog scale and Western Ontario and McMaster Universities Arthritis Index ( P ≤ 0.05) in favor of corticosteroids and oxygen-ozone groups after 1 wk and in favor of oxygen-ozone and prolotherapy groups after 8 wks. CONCLUSIONS: All three treatment options are effective for patients with pes anserine bursitis. This study showed that the effects of oxygen-ozone injection and prolotherapy last longer than those of corticosteroid injection.

Ultrasound-guided 5% dextrose prolotherapy versus corticosteroid injection in carpal tunnel syndrome: a randomized, controlled clinical trial.

Aim: The main assessment of this study is to analyze the efficiency of ultrasound-guided dextrose prolotherapy against corticosteroid injections for the treatment of carpal tunnel syndrome. Materials & methods: A total of 54 patients with carpal tunnel syndrome were included. Patients who were assigned into the prolotherapy group were injected with 5cc 5% dextrose water under ultrasound guidance. Patients in the corticosteroid group received ultrasound-guided 1 ml triamcinolone 40 mg/ml injection. Results: The inter-group analysis revealed that dextrose prolotherapy has a similar efficacy as corticosteroid for improving pain intensity, functional limitation in daily life, electrophysiologic parameters and ultrasonographic outcomes. No remarkable difference was found between the two treatments until 3 months of follow-up. Conclusion: Dextrose 5% has similar efficacy as triamcinolone for improving pain intensity, functional limitation in daily life, electrophysiologic parameters and ultrasonographic outcomes.

Effectiveness of acromioclavicular joint mobilization and physical therapy vs physical therapy alone in patients with frozen shoulder: A randomized clinical trial.

OBJECTIVES: The objective of this trial was to compare the efficacy of acromioclavicular joint mobilization and standard physical-therapy versus physical-therapy alone in the treatment of the frozen shoulder. DESIGN: Single-blind randomized clinical trial. SETTING: Outpatient setting. SUBJECTS: Patients with frozen shoulder. INTERVENTION: Participants were randomly allocated into mobilization + physical-therapy (n = 28), and physical-therapy alone (n = 28) groups for one month. MAIN MEASURES: The primary outcomes were the shoulder pain and disability index and the shoulder range of motion. The secondary outcome was the visual analogue scale. Measures were performed at the baseline, immediately and one month after the beginning of the treatment. RESULTS: Visual analogue scale and the shoulder pain and disability index improved more significantly in the mobilization group compared to the physical-therapy group immediately [-4.63 (-5.58--3.67) vs. -2.22 (-2.96--1.47), P < 0.001 and -23.08 (-28.63--17.53) vs. -13.04 (-17.93--8.16), P = 0.008, respectively] and one month after the beginning of the treatment [-5.58 (-6.45--4.72) vs. -3.61 (-4.60--2.62), P < 0.001 and -33.43 (-40.85--26.01) vs. -20.03 (-26.00--14.07), P = 0.001, respectively]. Active abduction range of motion was also improved more significantly immediately after the treatment in the mobilization group compared to the physical-therapy group [25.83 (11.45-40.13) vs. 10.17 (1.02-19.15), P = 0.025], however there were no significant differences between two groups concerning other measured range of motions. CONCLUSIONS: Adding acromioclavicular mobilization to standard physical-therapy was more efficient in decreasing pain and disability and improving active abduction range of motion compared to standard physical-therapy in frozen shoulder patients.

Lower serum levels of alpha tocopherol and lycopene are associated with higher pain and physical disability in subjects with primary knee osteoarthritis: A case-control study.

Background: We aimed to determine dietary intake and serum concentration of α-tocopherol and lycopene in subjects with knee osteoarthritis (KOA) in relation to pain intensity and functional status and comparing them with healthy controls. Methods: This case-control study was conducted among 35 patients with primary KOA and 35 matched healthy subjects selected using convenience sampling method. Dietary intakes of alpha-tocopherol and lycopene were estimated from 24-hour dietary records. Visual Analogue Scale (VAS) and Western Ontario and McMaster (WOMAC) index were used to assess the pain and functional status, respectively. Results: Serum concentrations of alpha-tocopherol (0.024 ± 0.005 vs. 0.028 ± 0.007 µmol/ml, p-value =  0.021) and lycopene (0.616 ± 0.191 vs. 0.727 ± 0.159 µmol/l, p-value = 0.011) were significantly lower in OA patients in comparison with healthy controls. Dietary intake of alpha-tocopherol was negatively associated with total WOMAC score (r = -0.401, p-value = 0.021) and pain (r = -0.356, p-value = 0.042) and physical function (r = -0.355, p-value = 0.043) subscales. Dietary intake of lycopene was negatively associated with total WOMAC score (r = -0.616, p-value < 0.001) and pain (r = -0.348, p-value = 0.047) and physical function (r = -0.606, p-value < 0.001) subscales. Additionally, serum concentration of alpha-tocopherol was negatively associated with total WOMAC score (r = -0.574, p-value < 0.001) and physical function subscale (r = -0.571, p-value < 0.001). Serum concentration of lycopene was negatively associated with total WOMAC score (r = -0.360, p-value = 0.040) and physical function subscale (r = -0.350, p-value = 0.046) Conclusion: Serum concentrations of α-tocopherol and lycopene were significantly lower in patients with KOA than in healthy controls. Significant negative association was detected between serum concentration and dietary intake of α-tocopherol and lycopene with functional disability in patients with KOA.

Comparison of efficacy of corticosteroid injection versus extracorporeal shock wave therapy on inferior trigger points in the quadratus lumborum muscle: a randomized clinical trial.

BACKGROUND: In this study, we aimed to compare the efficacy of corticosteroid trigger point injection (TPI) versus extracorporeal shock wave therapy (ESWT) on inferior trigger points in the quadratus lumborum (QL) muscle. METHODS: In this single-blind randomized clinical trial, 54 low back pain patients with myofascial trigger points on QL muscle were investigated. Participants were randomly allocated into two groups with A and B pockets. Patients in group A underwent radial ESWT and received 5 treatment sessions (1 per week) and actually were not followed-up. However, patients in group B received corticosteroid TPI and received one session of corticosteroid treatment and followed-up for 4 weeks after injection. Oswestry Disability Index (ODI), visual analogue scale (VAS), pain pressure threshold (PPT) and short form (36) health survey (SF-36) were measured in both groups before, two weeks after and four weeks after intervention. RESULTS: The between group comparison indicated that corticosteroid TPI leaded to significant higher improvements of ODI (P-value< 0.01), VAS (P value< 0.001), and PPT (P-value = 0.001) scores compared to the ESWT group at two-week follow-up time-point. ESWT group recorded significant higher improvement of ODI (P-value< 0.01) and SF-36 (P-value< 0.001) compared to the corticosteroid TPI at 4th week post treatment evaluation. At four-week follow-up time-point, the patients in the ESWT group were 1.46 times more likely to achieve 30% reduction in VAS, 2.67 times more likely to achieve 30% reduction in ODI, and 2.30 times more likely to achieve 20% improvement in SF-36 compared to the participants in corticosteroid TPI group. These results refer to large effect size for all study outcomes in ESWT group (d = 4.72, d = 1.58, d = 5.48, and d = 7.47 for ODI, PPT, SF-36, and VAS, respectively). CONCLUSION: Corticosteroid TPI was more effective compared to ESWT in short-term controlling of pain and disability caused by myofascial pain syndrome of QL muscle. However, after 4 weeks treatment, ESWT further improved the quality of life and disability and was related with more probability of achievement the minimal clinically important difference concerning pain, disability and quality of life and large effect size for all study outcomes in treated patients compared to corticosteroid TPI.

Beliefs, attitude, and knowledge of the Iranian physiatrists towards neuromusculoskeletal ultrasound and common barriers in its application.

BACKGROUND: Regarding the increasing application of neuromusculoskeletal sonography among medical specialties, specifically physiatrists, this study aims to assess the knowledge and skill level of these specialists in neuromusculoskeletal sonography in Iran. METHODS: This descriptive, cross-sectional study was performed in 2018. The utilized questionnaire developed based on previous studies in collaboration with 6 university lecturers of Shaheed Beheshti, Iran, and Tabriz medical universities and a physiatrist from Hacettepe University (Turkey); it included questions entailing demographic data, knowledge, and performance levels. Its validity and reliability were evaluated through face validation, pilot study, and the Cronbach α calculated via SPSS. Data extraction and analysis were also performed by SPSS-25. RESULTS: Of 364 questionnaires distributed, 300 were properly filled and entered into the study, of which, 38% were filled by clinical residents, 10% university lecturers, and 52% other categories (e.g. private sector). The average number of musculoskeletal patient visits was 140.6 ± 119 and the mean number of musculoskeletal sonographies requested was 8.2 ± 5.2 per month (the three most common indications reported as the shoulder, carpal tunnel syndrome, and tendon injuries). 95% of the participants considered the importance of sonography for physiatrists to be "very high" or "high"; with the most valuable applications "as a guide for procedures (90%), its diagnostic utility (68%), and follow up/evaluating the response to treatment (45%). 86% of physiatrists reported they had participated in musculoskeletal sonography courses, 60% during residency, and the rest through workshops. Also, the participants mentioned safety (83%), the possibility of performing simultaneous diagnosis and intervention procedures (70%), repeatability (58%), and dynamic imagery (52%) as the major advantages of musculoskeletal ultrasound. CONCLUSION: a large number of doctors consider musculoskeletal sonography to be essential for physiatrists, though insufficient education on the subject and the low number of ultrasound devices are some of the obstacles in enhancing the use of this technology in PM&R setting. Presenting certified specific training courses during residency, provision of necessary rotations, using the capacities of the PM&R scientific committee, and the private sector for running workshops and professional training courses are suggested for enhancing the knowledge and skills of neuromusculoskeletal sonography.

Ultrasound-Guided Corticosteroid Injection in Carpal Tunnel Syndrome: Comparison Between Radial and Ulnar Approaches.

PURPOSE: To compare two common approaches for ultrasonography (US)-guided injection. PATIENTS AND METHODS: Sixty patients with mild-to-moderate CTS were included in this double-blind randomized controlled trial (RCT). They received a single shot of corticosteroid injection through either the US-guided in-plane approach: radial or ulnar side. Participants were evaluated using Boston Carpal Tunnel Questionnaire (BCTQ) and visual analogue scale (VAS) for pain, as well as electrodiagnosis (EDX) and US parameters before the intervention, and within 12 weeks of follow-up. RESULTS: In both groups, all outcomes, except for the electrodiagnostic measures, significantly improved within the follow-up. Pain-VAS and both subscales of BCTQ questionnaire, as our main subjective outcomes, revealed dramatic improvement, with the largest amount of changes in VAS (70%; comparing to baseline value), and about 37% for both of BQSS and BQFS scales, all indicating superiority of radial to ulnar in-plane approach. During the first follow-up, we did not detect any remarkable preference between the groups in either subjective or electrodiagnostic variables. However, there was a significant difference at next follow-up time-points in terms of VAS for pain and BQFS favoring radial approach (Table 3). Furthermore, US-measured parameters including nerve-circumference and CSA improved only in the radial in-plane group. CONCLUSION: The current data proved that radial in-plane approach for CTS injection could be at least as effective as the more common ulnar in-plane method. Even the pain-relief effect was longer for the radial in-plane approach. Also, patients' functional status and objective variables all revealed better outcomes via the new approach.

A Randomized Control Trial of Comparing Ultrasound-Guided Ozone (O2-O3) vs Corticosteroid Injection in Patients With Shoulder Impingement.

INTRODUCTION: Ozone has been recently used as a safe alternative treatment in musculoskeletal disorders with fewer adverse effects than corticosteroids. The aim of this study was to compare the efficacy of a single injection of ozone with that of a corticosteroid in the treatment of shoulder impingement. DESIGN: Thirty patients with shoulder pain and clinical signs and symptoms of impingement were randomly assigned into two groups: ultrasound-guided injection with ozone or corticosteroid. Patients' symptoms were evaluated by visual analog scale, constant score, shoulder pain and disability scale, shoulder range of motion, and ultrasonographic measures before treatment, 2 wks, and 2 mos after injections. RESULTS: Patients' visual analog scale, shoulder pain and disability scale and constant score improved significantly in both groups (P < 0.001), but the benefits were in favor of corticosteroid group (P < 0.001). At intervals between the two follow-ups, an improvement was observed in the visual analog scale score among patients receiving ozone, whereas during the same interval, patients' pain slightly worsened in the corticosteroid group. The range of motion and ultrasonographic measures did not show statistical differences between the two groups. CONCLUSIONS: Corticosteroid injection improves the pain and disability scores more significantly than a one-time ozone injection. Ozone may serve as an alternative modality in treating shoulder impingement when the use of steroids is contraindicated.

Ultrasonographic Assessment of Carpal Tunnel Syndrome Severity: A Systematic Review and Meta-Analysis.

OBJECTIVE: The aim of the study was to investigate the overall estimates of cross-sectional areas of the median nerve measured by ultrasonography in accordance with the electrodiagnostic classification of carpal tunnel syndrome severity. DESIGN: MEDLINE (PubMed), Embase (Ovid), and Web of Science were searched for studies reporting the median nerve cross-sectional area measured by ultrasonography for mild, moderate, and severe carpal tunnel syndrome based on electrodiagnostic study. Cross-sectional area values measured at the carpal tunnel inlet were included in the analyses. RESULTS: Overall, 866 citations were retrieved and checked for eligibility. Finally, 16 articles were included for meta-analysis. These studies included a total sample of 2292 wrists including 776 mild, 823 moderate, and 693 severe carpal tunnel syndrome. The pooled analysis revealed a mean cross-sectional area of 11.64 mm (95% confidence interval = 11.23-12.05 mm, P < 0.001) for mild carpal tunnel syndrome, a mean cross-sectional area of 13.74 mm (95% confidence interval = 12.59-14.89 mm, P < 0.001) for moderate carpal tunnel syndrome, and a mean cross-sectional area of 16.80 mm (95% confidence interval = 14.50-19.1 mm, P < 0.001) for severe carpal tunnel syndrome. CONCLUSIONS: This is the first meta-analysis that provides the pooled median nerve cross-sectional area values in accordance with the electrodiagnostic classification of carpal tunnel syndrome severity. The values obtained in this study have clinical utility in ultrasonographic assessment of patients with carpal tunnel syndrome.

Comparison of Ultrasound-Guided Local Ozone (O2-O3) Injection vs Corticosteroid Injection in the Treatment of Chronic Plantar Fasciitis: A Randomized Clinical Trial.

OBJECTIVE: Plantar fasciitis (PF) is one of the most common causes of heel pain. The affected area is often close to the attachment of plantar fascia to calcaneus bone. The purpose of this study was to compare the effects of ozone (O2-O3) injection to corticosteroid injection under ultrasound guidance for the treatment of chronic PF. DESIGN: Randomized clinical trial. SETTING: Academic University and Neuromusculoskeletal Research Center. SUBJECTS: Thirty patients with chronic PF. METHODS: The patients were randomly divided into two groups receiving methylprednisolone (15 subjects) vs ozone (O2-O3; 15 subjects). The following outcome measures were assessed before injection and then two weeks and 12 weeks after the injection in each group; morning and daily pain via visual analog scale, daily life and exercise activities via the Foot and Ankle Ability Measure, and plantar fascia thickness at insertion and 1 cm distal to its insertion into the calcaneus via ultrasound imaging. RESULTS: Intragroup changes showed significant improvement in pain, functional parameters, and sonographic findings in both groups (P < 0.05). Pain reduction (both daily and morning) and daily activity improvement were better in the corticosteroid group two weeks after injection; however, at 12 weeks, the ozone (O2-O3) group had significantly more improvement (P = 0.003, P = 0.001, and P = 0.017, respectively). CONCLUSIONS: Both methods were effective in the treatment of chronic PF. Steroid injection provided a more rapid and short-term therapeutic effect. However, ozone (O2-O3) injection led to a slow and longer-lasting treatment outcome. Ozone (O2-O3) injection can be an effective treatment, with slow onset and a longer durability in the treatment of chronic PF.

Combination of Exercise and Acupuncture Versus Acupuncture Alone for Treatment of Myofascial Pain Syndrome: A Randomized Clinical Trial.

Myofascial pain syndrome (MPS) is a common musculoskeletal disorder. This study was designed to compare the effects of aerobic exercise plus acupuncture with acupuncture alone in treatment of patients with MPS. Sixty-four patients (55 female and 9 male) with MPS in their neck and shoulders participated in the study with mean age of 33.1 ± 6.4 years. Participants were randomly allocated to aerobic exercise plus acupuncture (n = 32) or acupuncture alone (n = 32) groups. Outcome measurements included visual analog scale, pressure pain threshold, neck disability index, and quality of life that was measured with QoL-SF36 scale. Each group received 10 sessions of acupuncture in combination with aerobic exercise or acupuncture alone. The outcome measures were evaluated at baseline, at the end of the last treatment session, and at 1-month follow-up visit. While participants were waiting for their 1-month follow-up visit, the patients who received combination therapy were asked to continue their aerobic exercise by jogging 40 minutes a day. Although mean visual analog scale, pressure pain threshold, neck disability index, and QoL-SF36 were significantly improved in both groups (p < 0.001), there was no statistically significant difference among the measures between the two groups throughout the evaluated sessions. The interaction effect of time and groups did not show any significant difference among the outcome measures (p > 0.29).

The effects of ultrasound-guided corticosteroid injection compared to oxygen-ozone (O2-O3) injection in patients with knee osteoarthritis: a randomized controlled trial.

Osteoarthritis (OA) is a chronic multifactorial disease characterized by progressive joint degeneration. The purpose of this study was to compare the effects of ultrasound-guided corticosteroid injection with oxygen-ozone injection in patients with knee OA. This double-blind randomized clinical trial was performed on 62 patients with knee OA. The patients were randomly divided into two groups. In the first group 40 mg triamcinolone (1 cc) and in the second group 10 cc (15 µg/ml) oxygen-ozone (O2-O3) were injected into the knee joint under ultrasound guidance. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis (WOMAC), knee flexion range of motion (ROM), effusion in ultrasound images of the suprapatellar recess, and visual analog scale (VAS), which were evaluated before injection, 1 week, 1 month, and 3 months after the treatment. Sixty-two patients (10 men and 52 women) were enrolled with mean age of 57.9 years. VAS improved in both groups (steroid P value = 0.001, oxygen-ozone P value > 0.001). The improvements seen in VAS and WOMAC scores 3 months after treatment were in favor of the oxygen-ozone group when compared to the steroid group (P = 0.041 vs P = 0.19). There was no significant difference between the two groups in ROM and joint effusion seen under ultrasound (ROM p = 0.880, effusion p = 0.362). However, in the oxygen-ozone-receiving group, joint effusion was decreased significantly (p < 0.001). Both steroid and oxygen-ozone injections are effective in patients with knee osteoarthritis. Our study showed that the effects of oxygen-ozone injection last longer than those of steroid injection to the knee joint.

Ultrasound-Guided Versus Landmark-Guided Local Corticosteroid Injection for Carpal Tunnel Syndrome: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: To review the literature and assess the comparative effectiveness of ultrasound-guided versus landmark-guided local corticosteroid injections in patients with carpal tunnel syndrome (CTS). DATA SOURCES: Cochrane Central Register of Controlled Trials, MEDLINE (PubMed), Embase (Ovid), and Web of Science (from inception to February 1, 2017). STUDY SELECTION: Randomized controlled trials (RCTs) comparing ultrasound-guided injection with landmark-guided injection in patients with CTS were included. DATA EXTRACTION: Two authors independently screened abstracts and full texts. The outcomes of interest were Symptom Severity Scale (SSS) and Functional Status Scale (FSS) scores of the Boston Carpal Tunnel Questionnaire and 4 electrodiagnostic parameters, including compound muscle action potential (CMAP), sensory nerve action potential (SNAP), distal motor latency (DML), and distal sensory latency (DSL). DATA SYNTHESIS: Overall, 569 abstracts were retrieved and checked for eligibility; finally, 3 RCTs were included (181 injected hands). Pooled analysis showed that ultrasound-guided injection was more effective in SSS improvement (mean difference [MD], -.46; 95% confidence interval [CI], -.59 to -.32; P<.00001), whereas no significant difference was observed between the 2 methods in terms of the FSS (MD, -.25; 95% CI, -.56 to .05; P=.10). There were also no statistically significant differences in improvements of CMAP (MD, 1.54; 95% CI, 0.01 to 3.07; P=.05), SNAP (MD, -0.02; 95% CI, -6.27 to 6.23; P>.99), DML (MD, .05; 95% CI, -.30 to .39; P=.80), or DSL (MD, .00; 95% CI, -.65 to .65; P>.99). CONCLUSIONS: This review suggested that ultrasound-guided injection was more effective than landmark-guided injection in symptom severity improvement in patients with CTS; however, no significant differences were observed in functional status or electrodiagnostic improvements between the 2 methods.

Effectiveness of Lavendula stoechas essential oil in treatment of mild to moderate carpal tunnel syndrome: A randomized controlled trial.

STUDY DESIGN: Randomized controlled trial. INTRODUCTION: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper extremity. To date, no previous study has evaluated the efficacy of topical Lavendula stoechas (Lavender) oil in CTS patients. PURPOSE OF THE STUDY: To investigate the effectiveness of topical Lavender essential oil in pain intensity, isometric pinch strength, electrophysiological features, and functional status of patients with mild to moderate CTS. METHODS: Forty eight patients with mild to moderate CTS were enrolled in this randomized placebo-controlled trial. Group A was treated with night wrist orthotic and topical lavender oil ointment. Group B was treated with night wrist orthotic and a placebo ointment. Patients were evaluated at baseline, and after 40 days of intervention with Boston CTS questionnaire (BCTQ), visual analog scale (VAS) for pain, pinch grip strength, power grip, median compound motor action potential latency, and median sensory nerve action potential latency. RESULTS: At the end of the study period, both groups improved significantly in terms of BCTQ, VAS, isometric pinch powers, and electrodiagnosis study parameters. However, group A showed significantly greater improvements in BCTQ (mean difference, 0.39 ± 0.31 vs 0.6 ± 0.35; P = .03), VAS (3.37 ± 1.86 vs 1.33 ± 2.07; P = .001), and pinch grip strength (0.73 ± 0.63 vs 0.27 ± 0.54; P = .01) than group B. No significant differences in power grip, median compound motor action potential latency, and median sensory nerve action potential latency were seen between the 2 groups. CONCLUSION: This study was the first trial of topical lavender oil used in patients with CTS. Wrist orthotic combined with topical lavender oil was more effective than orthotic and placebo in treatment of mild to moderate CTS. LEVEL OF EVIDENCE: 1b.

Comparison Between Effectiveness of Ultrasound-Guided Corticosteroid Injection Above Versus Below the Median Nerve in Mild to Moderate Carpal Tunnel Syndrome: A Randomized Controlled Trial.

OBJECTIVE: In this study, the clinical effectiveness of ultrasound-guided corticosteroid injection "above" versus "below" the median nerve for treatment of patients with mild to moderate carpal tunnel syndrome was compared. DESIGN: This prospective randomized double-blind clinical trial included 44 patients with mild to moderate carpal tunnel syndrome. The subjects were randomly assigned to two groups to receive ultrasound-guided injection of 40 mg of triamcinolone either "above" or "below" the involved median nerve. Outcome measures were the Boston Carpal Tunnel Questionnaire, visual analog scale, electrophysiological tests, and ultrasonographic measurement of the median nerve cross-sectional area at baseline, 6, and 12 wks after the injection. RESULTS: All outcome measures improved significantly in both groups at 6 wks after intervention, and these improvements were persevered up to 12 wks of follow-up (all P values <0.05). However, there was no significant difference in measured outcomes between the two groups. No adverse effects were observed. CONCLUSIONS: Both above and under median nerve ultrasound-guided steroid injection techniques were effective in reducing the symptoms, improving the function, and improving electrodiagnostic and sonographic findings of carpal tunnel syndrome. However, the amount of improvement in the outcomes did not differ between groups, implying that none of technique has the superiority over another.

Traumatic lower extremity and lumbosacral peripheral nerve injuries in adults: Electrodiagnostic studies and patients symptoms.

BACKGROUND: Peripheral nerve injuries (PNI) are relatively common pathologies in clinical practice. PNIs are rare in the lower extremity but have worse prognosis than those in the upper extremity. Electrodiagnostic studies could help better understanding PNIs. In this study, we aimed to evaluate the distribution of lower extremity PNI in traumatic patients in northwest of Iran. METHODS: In this prospective study, 74 patients (62 male and 12 female with mean age of 38.39 ± 14.42 years) with possible lower or lumbosacral peripheral nerve injury were studied. Patients' demographic information and physical examination findings were recorded. Electrodiagnostic investigations including electromyography and Nerve Conduction Study were performed for all subjects. RESULTS: Common chief complaints were pain and weakness. Impairment in the sensory function was present in 59.5% and muscle force reduction in 47.3%. PNIs were present in 23.0% and mostly were severe. Injuries in sciatic nerve were the most common PNIs (16.2%). Electrodiagnostic studies showed radiculopathy in 48.7% and plexopathy in 8.10% of cases. In 52 patients (70.3%), the physical examination findings were compatible with Electrodiagnostic studies. CONCLUSION: Not all patients presenting with traumatic injuries have lower extremity PNIs. Due to the nature of the trauma and the anatomical course of the nerves, sciatic nerve is more susceptible to traumatic injuries.

Reliability and validity of the Persian translation of Berg Balance Scale in Parkinson disease.

PURPOSE: Parkinson disease (PD) is one of the common causes of imbalance, and the balance assessment is necessary for treatment and rehabilitation of these patients. The Berg Balance Scale (BBS) has been the main instrument used to evaluate balance impairment. The purpose of this study is to investigate reliability and validity of the Persian translation of BBS in Parkinson disease. METHODS: One hundred PD patients (with mean age of 56.8 ± 15.13 years) were included. Interrater reliability was measured with the Kappa statistics and interclass correlation coefficients. RESULTS: The mean values of the BBS scored by the two evaluators were 47/85 ± 11/09 and 48/03 ± 10/90, respectively. The mean of Kappa coefficient between two examiners was 0.76, which was between 0.38 and 0.93 for various items. The total score recorded by both examiners, interclass correlation coefficient, was 0.99, which is excellent. Cronbach's alpha for Iranian version of BBS was 0.92, which shows the excellent reliability of the questionnaire (0.62-0.9 for all items). CONCLUSION: The Persian version of the BBS has excellent interrater reliability and internal consistency for the assessment of PD patients.

A Randomized Prospective Comparison of Ultrasound-Guided and Landmark-Guided Steroid Injections for Carpal Tunnel Syndrome.

PURPOSE: The aim of this study was to compare the clinical and electrodiagnostic efficacy of ultrasound (US)-guided versus landmark (LM)-guided steroid injections in patients with carpal tunnel syndrome (CTS). METHODS: This randomized clinical trial included 47 patients (60 affected hands) with moderate CTS (30 hands in each group). All clinically suspected patients with CTS who met the inclusion criteria confirmed by electrodiagnostic tests were enrolled. The subjects received 40 mg of methylprednisolone either with the US-guide or the LM-guided injection technique. They were evaluated using the Boston Carpal Tunnel Questionnaire (symptom/function/total) and 6 electrodiagnostic findings at the baseline and 12 weeks after injection. RESULTS: Symptom severity scores and functional status scores and electrodiagnostic parameters were significantly improved within each group at week 12 after treatment (P < 0.05), except for compound muscle action potential amplitude and motor nerve conduction velocity (P > 0.05). The improvement in symptom severity scores and functional status scores in the US-guided group was more than in the LM-guided group after 12 weeks, but there was no statistically significant difference (P = 0.79 and 0.64). The mean changes in electrodiagnostic parameters were also not different between groups except for the higher sensory nerve action potential amplitude in LM-guided group (P = 0.003). CONCLUSIONS: Both US-guided and LM-guided steroid injections were effective in reducing the symptoms, improving the function and electrodiagnostic findings of CTS. Although there was better symptomatic improvement with US-guided injections and better increase in sensory nerve action potential amplitude with LM-guided injection, a significant difference was not generally observed between US-guided and LM-guided CTS injections.

Dry needling in patients with chronic heel pain due to plantar fasciitis: A single-blinded randomized clinical trial.

BACKGROUND: This study examined the effects of dry needling on chronic heel pain due to plantar fasciitis. METHODS: During this single-blinded clinical trial, 20 eligible patients were randomized into two groups: A case group treated with dry needling and a control group. Patients' plantar pain severity, (using modified visual analog scale [VAS] scoring system), range of motion of ankle joint in dorsiflexion [ROMDF] and plantar extension[ROMPE] and foot function index (using standard questionnaires of SEM5 and MDC7) were assessed at baseline, four weeks after intervention and four weeks after withdrawing treatment. Independent sample t-test, Mann-Whitney U test, paired t-test, Wilcoxon signed rank tests, and chi square test were used for data analysis. RESULTS: The mean VAS scores in the case group was significantly lower than the control group after four weeks of intervention (p<0.001). Comparison of the ROMDF and ROMPE did not reveal any significant changes after four weeks of intervention in the case and control groups (p=0.7 and p=0.65, respectively). The mean of MDC7 and SEM5 scores in the case group were significantly lower than the control group following four weeks of intervention (p<0.001). CONCLUSION: Despite the insignificant effect on ROMDF and ROMPE, trigger point dry needling, by improving the severity of heel pain, can be used as a good alternative option before proceeding to more invasive therapies of plantar fasciitis.

Familial Amyloid Polyneuropathy Type IV (FINNISH) with Rapid Clinical Progression in an Iranian Woman: A Case Report.

Familial amyloid polyneuropathy (FAP) type IV (FINNISH) is a rare clinical entity with challenging neuropathy and cosmetic deficits. Amyloidosis can affect peripheral sensory, motor, or autonomic nerves. Nerve lesions are induced by deposits of amyloid fibrils and treatment approaches for neuropathy are challenging. Involvement of cranial nerves and atrophy in facial muscles is a real concern in daily life of such patients. Currently, diagnosis of neuropathy can be made by electrodiagnostic studies and diagnosis of amyloidosis can be made by genetic testing or by detection of amyloid deposition in abdominal fat pad, rectal, or nerve biopsies. It is preferable to consider FAP as one of the differential diagnosis of a case presented with multiple cranial nerves symptoms. The authors present a case of familial amyloid polyneuropathy (FAP) type IV with severe involvement of multiple cranial nerves, peripheral limb neuropathy, and orthostatic hypotension.
