A comparison between hypertonic dextrose prolotherapy and conventional physiotherapy in patients with knee osteoarthritis.

The aim of the present study was to compare the efficacy of hypertonic dextrose prolotherapy (HDP) with conventional physiotherapy (CPT) in improving symptoms in females with knee osteoarthritis (OA). The present study included 60 patients with a diagnosis of knee OA. The patients were randomly assigned to the HDP (n=30) and CPT (n=30) groups. The patients in the HDP group were treated with a dextrose injection into the knee joint (25% dextrose) and around the knee (15% dextrose) in two sessions for 1 month, while those in the CPT group received a hot pack, transcutaneous electrical nerve stimulation and therapeutic ultrasound in five sessions a week for 4 weeks. Prior to commencing the treatment, and at 1 and 3 months post-treatment, all the patients were evaluated using the visual analog scale (VAS), Western Ontario and McMaster Osteoarthritis Index (WOMAC), the goniometric measurement of active knee range of motion (ROM), a 50-m walking test and isokinetic knee muscle strength measurements. There were no statistically significant differences between the two groups as regards the demographic characteristics at pre-treatment (P>0.05). However, at 1 and 3 months post-treatment, the scores of all the outcome parameters were significantly improved in the HDP group compared with the CPT group (P<0.05 for all). In both groups, a significant improvement was observed in the VAS scores, WOMAC total values and ROM following the treatments, with the greatest improvement observed in the HDP group (P<0.001). The isokinetic quadriceps peak torque measurements were increased in both groups following treatment. All the scores exhibited a statistically significant improvement in the HDP group at both 1 and 3 months post-treatment. On the whole, the results of the present study demonstrate that both HDP and CPT are effective treatment modalities to relieve pain, and increase functionality and strength in patients with knee OA. However, greater improvements in pain and functionality can be achieved with prolotherapy.

Short­term effects of pregabalin plus exercise therapy on pain, emotional status, physical function and nociceptive responses in patients with fibromyalgia.

The aim of the present study was to investigate the effects of pregabalin plus exercise vs. pregabalin treatment alone on the electromyographic nociceptive flexion reflex (NFR) threshold in patients with fibromyalgia (FM). For this purpose, the present study included a total of 40 patients diagnosed with FM according to the American College of Rheumatology 2010 criteria. The patients were divided into two groups as follows: Group 1 received pregabalin treatment only and group 2 received exercise therapy in addition to pregabalin treatment. Assessments were made at baseline and at the 1st month using a visual analog scale (VAS) to measure pain, the Fibromyalgia Impact Questionnaire (FIQ) to measure the severity of FM, Beck's Depression Inventory (BDI) to measure depression and the NFR to measure the compressive forces on peripheral nerves. In both groups, the NFR threshold following treatment was significantly higher than that at the baseline results (P#x003C;0.001). There was no significant difference between the groups as regards the difference from pre- to post-treatment NFR threshold values (P=0.610 and P=0.555, respectively). There was a strong, negative correlation between the pre-treatment NFR threshold and VAS resting, VAS motion and FIQ scores (Rho=-0.62, Rho=-0.69 and Rho=-0.60, respectively). There was a moderate negative correlation between the pre-treatment NFR threshold and BDI scores (Rho=-0.35). On the whole, the present study demonstrates that in the treatment of FM, pregabalin improves the clinical scores and leads to an increase in the NFR threshold. Herewith, it should be noted that short-term exercise therapy does not appear to provide additional benefits.

The effect of oral baclofen and botulinum toxin treatments in hemiplegic spasticity on the nociceptive flexor reflex: A randomized clinical trial.

Objectives: This study aimed to analyze the effect of oral baclofen treatment and botulinum toxin type A (BT-A) injection treatment in hemiplegic patients with spasticity on the electromyographic nociceptive flexor reflex (NFR) threshold. Patients and methods: A total of 29 spastic hemiplegic patients (20 males, 9 females; mean age: 52.9±10.1; range, 27 to 64) with Modified Ashworth Scale (MAS) grades 2-4 were included in the prospective, randomized study between May 2018 and March 2019. The patients were divided into two groups: the BT-A group consisted of 15 patients that underwent a BT-A injection and the baclofen group consisted of 14 patients treated with baclofen. Modified Ashworth Scale, Visual Analog Scale (VAS), Barthel daily life activity index, and NFR threshold values were used in the evaluation of the patients before and after the treatment at the sixth week. The motor evaluation of the patients was performed using Brunnstrom motor staging. Results: In both groups, MAS and VAS values decreased significantly compared to pretreatment (p<0.05). There was a significant decrease in ankle MAS score (p<0.001) and a significant increase in Brunnstrom hand recovery stages in the BT-A group compared to pretreatment (p=0.020). While the NFR threshold statistically significantly increased in the baclofen group compared to pretreatment (p=0.007), there was no significant change in the BT-A group (p=0.669). Conclusion: These results suggest that BT-A injections do not cause a significant change in the NFR threshold in the treatment of spasticity.

Effects of radial extracorporeal shock wave therapy on clinical variables and isokinetic performance in patients with knee osteoarthritis: a prospective, randomized, single-blind and controlled trial.

OBJECTIVE: This study aims to compare the efficacy of r-ESWT treatment with sham-ESWT on pain, walking speed, physical function, and isokinetic muscle strength in knee osteoarthritis. METHODS: The study included 104 patients (mean age 61.0 ± 6.2 years; range 50 to 70 years) who were admitted to our outpatient clinic with newly diagnosed with knee osteoarthritis. Patients were randomly assigned to two groups. Both groups received transcutaneous electrical nerve stimulation for 30 minutes, hot pack for 40 minutes, and home-based exercise program of around the knee strengthening for 30 minutes in a day for three weeks (5 days in a week). Also, one group was treated with r-ESWT, while the other group was treated with sham-ESWT. For r-ESWT, patients received 2000 pulses of shockwave at 2.0 to 3.0 bar weekly for three weeks. All patients were evaluated with visual analog scale (VAS), active knee range of motion (ROM), 20-metre walk test, Western Ontario and McMaster Osteoarthritis Index (WOMAC), Lequesne's disability index, and isokinetic muscle performance before treatment, at the end of treatment, at one month and three months after treatment. RESULTS: When groups were compared, group 1 scores were significantly better than the group 2 in all outcome parameters except WOMAC-stiffness at the end of treatment, at one month and three month follow-up (all p < 0.05). The VAS-resting, VAS-movement, knee ROM, 20-m walk test, WOMAC, and Lequesne's disability scores and peak torque values of knee extension improved in both groups with the highest improvement in the r-ESWT group. A comparison of difference of the two group scores showed statistically significant superior improvement in group 1 in all parameters at both one month and three months. CONCLUSION: Our findings revealed that r-ESWT combined with conventional electrotherapy is an effective treatment for improving pain and physical function in knee osteoarthritis to control symptoms up to three months.

Does Kinesiology Taping Improve Muscle Strength and Function in Knee Osteoarthritis? A Single-Blind, Randomized and Controlled Study.

OBJECTIVES: This study aims to evaluate the efficacy of kinesiology taping (KT) on pain, movement restriction, walking speed, daily living activities, and isokinetic muscle performance in female patients with knee osteoarthritis. PATIENTS AND METHODS: The study included 61 female patients (mean age 53.5±3.5 years; range 50 to 60 years) who were admitted to Physical Medicine and Rehabilitation Outpatient Clinic with complaints of mechanical knee pain. Knee osteoarthritis was diagnosed according to the clinical/ radiological criteria of the American College of Rheumatology and patients with Kellgren-Lawrence grade 2 and 3 were included. Patients were randomly divided into two groups. Both groups received transcutaneous electrical nerve stimulation for 30 minutes, hot pack for 30 minutes, and therapeutic ultrasound for 10 minutes in a day for three weeks (five days in a week). Also, one group was treated with KT (KT group, n=31) while the other group was treated with sham-KT (sham-KT group, n=30) one time a week for three weeks. A home program of around the knee strengthening exercises was recommended for all patients. All patients were evaluated with visual analog scale, Western Ontario and McMaster Osteoarthritis Index (WOMAC) values, goniometric measurement of active knee range of motion, 50-meter walking distance, and isokinetic knee extensor muscle peak torque measurements before treatment, at the end of treatment, and at one month and three months after treatment. RESULTS: There was a significant improvement in after treatment and first month visual analog scale values in the KT group compared to the sham-KT group (p<0.05). In the KT group, the WOMAC pain and WOMAC total scores decreased significantly after treatment compared to the sham-KT group (p<0.05). Visual analog scale values were significantly decreased after treatment in both groups (p<0.05). In both groups; WOMAC pain, stiffness, physical function, and total values decreased significantly after treatment (p<0.05). In both groups, isokinetic quadriceps peak torque measurements were increased after treatment (p<0.05). CONCLUSION: The application of KT to females with knee osteoarthritis appears to be a method that may be effective on pain and functional capacity.

Does transcutaneous nerve stimulation have effect on sympathetic skin response?

OBJECTIVE: This study examined the effects of transcutaneous electrical nerve stimulation (TENS) on the sympathetic nerve system by sympathetic skin response test. METHODS: Fifty-five healthy volunteers received either: (i) 30minutes TENS (25 participants) (ii) 30minutes sham TENS (30 participants) and SSR test was performed pre- and post-TENS. The mean values of latency and peak-to-peak amplitude of five consecutive SSRs were calculated. RESULTS: A significant amplitude difference was found between TENS and sham TENS group both in right and left hand (p=0.04, p=0.01, respectively). However there was no significant latancy difference between two groups (p>0.05 ). CONCLUSION: TENS has an inhibitory effect on elicited SNS responses when compared with sham TENS control group.

The Effect of Anti-Tumor Necrosis Factor-Alpha Treatment on Muscle Performance and Endurance in Patients With Ankylosing Spondylitis: A Prospective Follow-Up Study.

OBJECTIVES: This study aims to evaluate muscle performance by using isokinetic dynamometer before and at third month of anti-tumor necrosis factor-alpha treatment in ankylosing spondylitis patients. PATIENTS AND METHODS: Thirty ankylosing spondylitis patients (23 males, 7 females; mean age 39.3±8.6 years; range 18 to 45 years) starting on anti- tumor necrosis factor-alpha treatment and 30 healthy controls (23 males, 7 females; mean age 39.1±8.8 years; range 18 to 48 years) with similar age, body mass index, and sex were enrolled. The clinical anthropometric measurements of chest expansion, lumbar Schober test, hand-finger floor distance and visual analog scale-global, C-reactive protein, erythrocyte sedimentation rate, Ankylosing Spondylitis Disease Activity Score-C-reactive protein and Ankylosing Spondylitis Disease Activity Score-erythrocyte sedimentation rate, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Metrology Index were determined before and at third month of the treatment. RESULTS: There was no statistically significant difference in age, sex and, body mass index between the groups (p>0.05). A statistically significant difference was detected between 60 °/second and 180 °/second peak torque in angular velocity of flexor and extensor muscles (p<0.05). A significant difference was detected in respect to total work of patients with 180 °/second peak torque in angular velocity of flexor and extensor muscles (p<0.05). There was a statistically significant difference between the findings of 60 °/second and 180 °/second peak torque in angular velocity of flexor and extensor muscles (p<0.05). Isokinetic test results were better at third month after treatment than before treatment. CONCLUSION: The results of this study showed that both functional limitations and performance and endurance of muscles may be improved with anti-tumor necrosis factor-alpha treatment in ankylosing spondylitis patients.

Assessment of the Anterior Talofibular Ligament Thickness in Patients with Chronic Stroke: An Ultrasonographic Study.

BACKGROUND: Patients with equinovarus deformity have an increased risk of fall and ankle ligament injury, because of inappropriate prepositioning of the ankle at the end of the swing phase, and inadequate leg and ankle stability during the stance phase. Accordingly, the aim of this study is to compare anterior talofibular ligament (ATFL) thickness of chronic stroke patients with that of healthy individuals using ultrasonography. METHODS: This was a case-control study conducted in a university hospital between July 2015 and July 2016. We included 38 patients [study group; mean age, 59.0 ± 11.1 years; mean body mass index (BMI), 25.4 ±4.3 kg/m2] and a control group of age-, sex-, and BMI-matched healthy individuals. Demographic and clinical characteristics of the patients (i.e., age, weight, height, Brunnstrom motor recovery stage, Functional Ambulation Scale, Ashworth Scale, and duration of hemiplegia) were recorded during their visits. Furthermore, ultrasound image of the ATFL was obtained from each ankle. The thickness of the ATFL was measured at the midpoint of the ligament between the attachments on the lateral malleolus and the talus using ultrasonography. RESULTS: In the study group, the mean thickness of the ATFLs of the affected side (2.75 ± 0.41 mm) was thicker than both the unaffected side (2.42 ± 0.30 mm) and the healthy controls (2.35 ± 0.19 mm; p = 0.007, p < 0.001, respectively). No differences were seen between the two sides of the control group. CONCLUSION: Chronic stroke patients have a thicker ATFL on both the affected and unaffected sides, compared with healthy individuals. This architectural feature of the ATFL may be a result of equinovarus deformity together with spastic muscles. For this reason, early treatment of deformed ligaments and spastic muscles is needed to prevent equinovarus deformity in patients with stroke.

Ultrasonographic Assessment of the Distal Femoral Cartilage Thickness in Patients with Homozygous Sickle Cell Disease.

OBJECTIVE: To compare the distal femoral cartilage thickness of patients with sickle cell disease (SCD) with those of healthy subjects using ultrasonography. METHODS: The study comprised 30 patients with SCD (16 male, 14 female; mean age, 30.1 years) and 30 age- and sex-matched healthy subjects. Demographic features and medications of the patients were recorded. With the knees held in maximum flexion, the femoral cartilage thickness was measured bilaterally with a 7- to 12-MHz linear probe. Using ultrasonography, 3 midpoint measurements were taken from both knees: lateral femoral condyle (LFC), intercondylar area (ICA), and medial femoral condyle (MFC). RESULTS: Patients with SCD had thinner femoral cartilage thickness values at LFC (P = 0.004), at MFC (P = 0.000), and ICA (P = 0.002) when compared with those of the healthy subjects. Patients with SCD also had lower Hb levels (P = 0.000) levels. Weak positive correlations were determined between Hemoglobin (Hb) levels and ultrasonographic measurements in the SCD group at MFC (r = 0.331, P = 0.010), and ICA (r = 0.289 , P = 0.025 ). Low levels of Hb seem to affect the femoral cartilage thickness. CONCLUSION: These preliminary findings of decreased femoral cartilage thickness in SCD patients should be complemented with future studies. The possibility of early knee joint degeneration and eventual osteoarthritis in SCD should be kept in mind.

Isokinetic Assessment of the Wrist Muscles in Females With Fibromyalgia.

OBJECTIVES: This study aims to evaluate wrist muscle strength and muscle fatigue in females with fibromyalgia syndrome (FMS) and compare the results with those of healthy controls. PATIENTS AND METHODS: Thirty consecutive female FMS patients (mean age 39.8±6.7 years; range 25 to 49 years) and 50 age and body mass index similar healthy females (mean age 35.4±7.9 years; range 27 to 48 years) were enrolled. Patients' clinical characteristics were recorded and symptoms were evaluated by the Fibromyalgia Impact Questionnaire. In addition to the demographic characteristics, physical activities of all subjects were questioned, isokinetic muscle performance was measured, and fatigue index was calculated by endurance test. RESULTS: The peak torque values of the wrist extensor and flexor muscles (at an angular velocity of 90°/second) were higher in the control group than in the FMS group (both p<0.01). There were no differences between the groups in terms of the fatigue indexes of the flexor and extensor muscles of the wrist (both p>0.05). While there were differences between the groups regarding weekly hours of walking (p=0.01) and house cleaning (p<0.001), no differences were determined for weekly hours of bicycling, gardening, doing sports, or total physical activity. There was no correlation between the peak torque values and clinical characteristics in FMS group. CONCLUSION: Patients with FMS had decreased muscle strength compared to healthy controls. Further studies with larger participants are needed to explain the relationship between upper limb muscle performance and FMS, as well as the underlying pathogenesis.

Isotretinoin treatment in patients with acne vulgaris: does it impact muscle strength, fatigue, and endurance?

The objective of this study was to evaluate the effects of isotretinoin on muscle strength, fatigue, and endurance in patients with acne vulgaris. The study included 27 patients with acne vulgaris who underwent treatment with isotretinoin as well as 26 control patients for comparison. Participants in the treatment group received oral isotretinoin 0.5 mg/kg once daily for 1 month followed by an increased dose of 1 mg/kg once daily for 2 months. Isokinetic measurements were obtained from the hamstrings and quadriceps on the nondominant side of the body at baseline and 3-month follow-up using an isokinetic dynamometer. Results indicated that systemic isotretinoin did not significantly alter muscle strength, fatigue, and endurance.

Left ventricular systolic dysfunction in patients with ankylosing spondylitis without clinically overt cardiovascular disease by speckle tracking echocardiography.

The aim of this study was to evaluate left ventricular systolic and diastolic function using speckle tracking echocardiography (STE) in order to detect subclinical left ventricular dysfunction in patients with ankylosing spondylitis (AS). Twenty-six AS patients (age 43.7 ± 11.8 years, disease duration 11.83 ± 10.98 years) and 26 healthy controls, matched for age, sex, body mass index, and smoking, were enrolled in this cross-sectional study. All patients underwent two-dimensional, Doppler, tissue Doppler, and speckle tracking echocardiography. The mitral early/late diastolic inflow velocity ratio (1.0 ± 0.4 vs. 1.5 ± 0.5; p < 0.001) and the mitral E-wave velocity (8.1 ± 2 vs. 11.1 ± 3; p < 0.001) were lower in the AS patients than in the controls. The ejection fraction did not differ between the patients and controls (64 ± 4.2 vs. 64.8 ± 2.3; p = 0.402). All segments showed a significant decrease in left ventricular diastolic and systolic strain values in the patients with AS when compared with the healthy controls (p < 0.001). Despite no clinical evidence of cardiovascular disease, patients with AS may have impaired left ventricular systolic function as assessed by STE.

Efficacy of EMLA cream phonophoresis comparison with ultrasound therapy on myofascial pain syndrome of the trapezius: a single-blind, randomized clinical study.

The aim of this study is to investigate whether eutectic mixture of local anesthetics (EMLA) cream phonophoresis superior to conventional US over the trigger points (TPs) in terms of improvements of pain, range of motion and disability in myofascial pain syndrome (MPS). Fifty patients (42 female, 8 male) diagnosed with MPS were included in the study. Patients were randomly assigned into two treatment groups including phonophoresis (PH) group (n = 25) and ultrasound (US) group (n = 25). PH group received EMLA cream phonophoresis (2.5 % lidocaine, 2.5 % prilocaine); US group received conventional ultrasound therapy over the all active TPs on trapezius muscle for 10 min a day for 15 sessions. Outcome measures were performed before the treatment course and at the end of a 15-session course of treatment. Student T, Mann-Whitney U, chi-square and Wilcoxon tests were used for statistical analysis. At the end of the therapy, there was statistically significant decrease in both PH group and US group in terms of number of trigger point (NTP) (p = 0.001, p = 0.029), pain intensity on movement (p = 0.001 vs. 0.002) and right/left cervical lateral ROMs (p = 0.001/p = 0.001, p = 0.009/p = 0.020) relative to baseline. The NTP decrease in PH group was significantly higher than that in US group (1.84 ± 1.46 vs. 0.72 ± 1.45; p = 0.01). Pain intensity at rest (p = 0.001) and NPDI scores (p = 0.001) were statistically improvement in only PH group. EMLA cream phonophoresis is more effective than conventional ultrasound therapy in terms of pain and associated neck disability, and it seems the complementary treatment option for MPS.

Ultrasound-guided vs. blind steroid injections in carpal tunnel syndrome: A single-blind randomized prospective study.

OBJECTIVE: The aim of this study was to compare the efficacy and the safety of ultrasound (US)-guided vs. blind steroid injections in patients with carpal tunnel syndrome (CTS). DESIGN: This prospective randomized single-blind clinical trial included 46 patients with CTS (46 affected median nerves). The subjects were randomized-to either the US-guided or the blind injection group-before they received 40 mg of methylprednisolone. They were evaluated using the Boston Carpal Tunnel Questionnaire symptom/function at baseline and at 6 wks and 12 wks after injection, and the side effects were noted. RESULTS: The symptom severity and functional status scores improved significantly in both groups at 6 wks after treatment, and these improvements persisted at 12 wks after treatment (all P < 0.05). The improvement in symptom severity scores in the US-guided group at 12 wks was higher than in the palpation-guided group (P < 0.05). Average time to symptom relief was shorter in the US-guided group (P < 0.05). There was no significant difference between the two groups in terms of side effects (P > 0.05). CONCLUSIONS: Although both US-guided and blind steroid injections were effective in reducing the symptoms of CTS and improving the function, an earlier onset/better improvement of symptom relief suggests that US-guided steroid injection may be more effective than are blind injections in CTS.
