Ultrasound versus palpation-guided corticosteroid injection for de Quervain disease: A randomized controlled trial.

INTRODUCTION: Corticosteroid injection effectively treats de Quervain disease, and due to the high prevalence of the intracompartmental septum in the first extensor compartment, ultrasound guidance improves injection accuracy. OBJECTIVE: To compare the effectiveness, adverse events, and the recurrence rate between ultrasound-guided and palpation-guided injection in patients with de Quervain disease. DESIGN: Prospective, single-blind, randomized controlled trial. SETTING: Rehabilitation department of a private teaching hospital. PARTICIPANTS: We enrolled 49 patients, ≥20 years of age, clinically diagnosed with de Quervain disease based on their medical history and physical examination. INTERVENTIONS: Patients were randomized into two groups: ultrasound-guided and palpation-guided injection. Both groups received a mixture of 10 mg triamcinolone acetonide (10 mg/1 mL) and 0.3 mL 1% lidocaine. MAIN OUTCOME MEASURES: The primary outcome measure was the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score at 1 week. The secondary outcome measures were visual analog scale for pain (pain VAS) score, patient satisfaction, and adverse events or complications from the interventions at 1 week, 3 months, and 6 months. RESULTS: Both groups showed improvement over time in QuickDASH scores and pain VAS (p < .001); however, no statistically significant differences were noted between the groups for either QuickDASH scores (p = .22) or pain VAS (p = .30). In addition, no statistically significant differences were found between the groups in terms of patient satisfaction (p = .76) and adverse events (p = .47, .33, .58) at the 1-week, 3-month, and 6-month follow-ups. CONCLUSIONS: Both ultrasound-guided and palpation-guided injections effectively treated de Quervain disease. During a 6-month follow-up, there were no statistically significant differences between the groups in pain relief, upper limb function, or patient satisfaction. However, the palpation-guided group showed a tendency for more recurrence and skin side effects.

Efficacy of Combination Therapy (Hydrodilatation and Subdeltoid Bursa Injection With Corticosteroid, Mobilization, and Physical Therapy) vs Physical Therapy Alone for Treating Frozen Shoulder: A Randomized Single-Blind Controlled Trial, Phase I.

OBJECTIVE: To compare the efficacy of combination therapy (hydrodilatation and subdeltoid bursa injection with corticosteroid, mobilization, and physical therapy [PT]) with that of PT alone for treating frozen shoulder. DESIGN: A prospective, 2-arm parallel, single-blinded, randomized controlled trial. SETTING: Rehabilitation clinic of a private academic hospital. PARTICIPANTS: Patients (n=70) with frozen shoulder (freezing stage). INTERVENTIONS: Participants (n=35) in the combination group underwent hydrodilatation and subdeltoid bursa injection with corticosteroid twice, mobilization, and usual-care PT for 8 weeks; participants (n=35) in the PT group received only the usual-care PT for 8 weeks. MAIN OUTCOME MEASURES: The Shoulder Pain and Disability Index (SPADI) was the primary outcome measure. The secondary outcome measures were pain scores on a visual analog scale, range of motion (ROM), the Shoulder Disability Questionnaire (SDQ), quality of life (evaluated using the 36-item Short-Form Health Survey [SF-36]), and self-assessment of the treatment effect. RESULTS: Compared with the PT group, the combination group had significantly better pain (during activity), SPADI, SDQ, active and passive ROM, and self-assessment scores (all P<.001) as well as scores on some parts of the SF-36 (physical function and bodily pain, P<.05). Between-group differences were significant at the 1-, 2-, 4-, and 6-month follow-ups. CONCLUSIONS: A combination of hydrodilatation (with corticosteroid), bursal corticosteroid injection, and joint mobilization with PT was superior to PT alone for treating frozen shoulder, and the effects persisted for at least 6 months.

Feasibility of predicting maximal oxygen uptake by using the efficiency factor in healthy men.

Conventionally, efficiency is indirectly estimated through a respiratory gas analyser (oxygen, carbon dioxide), which is a complex and rather costly calculation method that is difficult to perform in many situations. Therefore, the present study proposed a modified definition of efficiency, called the efficiency factor (EF) (i.e., the ratio of work to the corresponding exercise intensity), and evaluated the relation between the EF and maximal oxygen uptake ([Formula: see text]), as well as compared the prediction models established based on the EF. The heart rate (maximal heart rate: 186 ± 6 beats min-1), rating of perceived exertion (19 ± 1), and [Formula: see text] (39.0 ± 7.1 mL kg-1 min-1) of 150 healthy men (age: 20 ± 2 years; height: 175.0 ± 6.0 cm; weight: 73.6 ± 10.7 kg; body mass index [BMI]: 24.0 ± 3.0 kg m-2; percent body fat [PBF]: 17.0 ± 5.7%) were measured during the cardiopulmonary exercise test (CPET). Through multiple linear regression analysis, we established the BMI model using age and BMI as parameters. Additionally, we created the PBF modelHRR utilizing weight, PBF, and heart rate reserve (HRR) and developed PBF modelEF6 and PBF modelEF7 by incorporating EF6 from the exercise stage 6 and EF7 from the exercise stage 7 during the CPET, respectively. EF6 (r = 0.32, p = 0.001) and EF7 (r = 0.31, p = 0.002) were significantly related to [Formula: see text]. Among the models, the PBF modelEF6 showed the highest accuracy, which could explain 62.6% of the variance in the [Formula: see text] at with a standard error of estimate (SEE) of 4.39 mL kg-1 min-1 (%SEE = 11.25%, p < 0.001). These results indicated that the EF is a significant predictor of [Formula: see text], and compared to the other models, the PBF modelEF6 is the best model for estimating [Formula: see text].

Comparison of corticosteroid injection, physiotherapy and combined treatment for patients with chronic subacromial bursitis - A randomised controlled trial.

OBJECTIVE: To investigate whether combination of corticosteroid subdeltoid injections and physiotherapy was more effective than either treatment alone in chronic subacromial bursitis. DESIGN: Prospective, three-arm randomised controlled trial. SETTING: Rehabilitation department of an academic hospital. SUBJECTS: Patients with chronic subacromial bursitis. INTERVENTIONS: Patients were divided into corticosteroid injection (N = 36), physiotherapy (N = 40) and combined (N = 35) groups. Two corticosteroid subdeltoid injections in corticosteroid group, 8-week physical therapy emphasising on therapeutic exercise in physiotherapy group, and combined both treatments in combined group. MAIN OUTCOME MEASURES: The primary outcome measures were pain visual analogue scale and Shoulder Pain and Disability Index at 8 weeks after finishing treatment. The secondary outcome measures were active range of motion, Shoulder Disability Questionnaire, Western Ontario Rotator Cuff Index, patient's evaluation of treatment effect, and symptom recurrence. RESULTS: Group comparison showed significant statistical difference in shoulder flexion (P < 0.003) and patient's evaluation of treatment effect (P < 0.001). The time and group interactions comparison revealed significant statistical differences in pain score (P < 0.024), external rotation (P < 0.044) and patient's evaluation of treatment effect (P < 0.001). The above statistics were in favour of the corticosteroid and combined groups rather than physiotherapy group. The percentage of recurrence was 36.1, 7.5 and 17.1 in the corticosteroid, physiotherapy and combined groups, respectively (P < 0.001). CONCLUSION: Corticosteroid subdeltoid injection, or combined with physiotherapy, was superior to physiotherapy alone, but the recurrence rate was least in the physiotherapy group.

Ultrasonographic imaging findings of the shoulder in patients with Parkinson disease.

BACKGROUND: Shoulder disorders, including frozen shoulder, bursitis, and rotator cuff lesions, are common musculoskeletal problems in patients with Parkinson disease (PD). Because musculoskeletal ultrasound (US) can clearly image shoulder joints, we aimed to evaluate shoulder joints using US in patients with PD and healthy participants and correlation between US and PD severity. METHODS: This is a prospective case-control study. 50 patients with PD and 50 healthy subjects from the outpatient department were administered US for bilateral shoulders. For data analysis, we chose the more severely affected side in the PD group for matching with the corresponding shoulder in the control group according to age, sex, and body mass index. Pain and disability were measured using the Visual Analogue Scale (VAS) for pain, Shoulder Pain and Disability Index (SPADI), and the Shoulder Disability Questionnaire (SDQ). RESULTS: The PD group had higher VAS pain scores during activity (p = 0.003) and rest (p < 0.001), as well as the SPADI and SDQ scores (p < 0.001). In US findings, biceps long head tendon sheath effusion (p = 0.001), humeral head cortical irregularity (p = 0.012), and abnormality in the supraspinatus tendon (p = 0.003) were significantly greater in the PD group. Intra-group analysis in the PD group demonstrated a significant difference in passive flexion (p = 0.019) and supraspinatus tendinopathy (p = 0.033) on US examination during different disease stages. CONCLUSIONS: Patients with PD had more supraspinatus tendinopathy on US findings than control subjects. The lesion was significantly associated with disease severity. CLINICAL TRIAL NUMBER: NCT02702232.

Comparison of the effects of ultrasound- guided needle puncture, radial shock wave therapy, and combined treatments on calcific tendinitis of the shoulder: A single-blind randomized controlled trial.

BACKGROUND: Calcific tendinitis of the shoulder is a common disorder resulting in restricted motion and pain. OBJECTIVE: This study compared the effects of ultrasound-guided fine-needle puncture (USNP), radial shock wave therapy (RSWT), and the combination of both treatments (COMB) on calcific tendinitis of the shoulder. METHODS: We enrolled 62 patients who had unilateral shoulder pain for more than 3 months. The patients were randomly divided into three groups: USNP, RSWT, and COMB. All USNP needle punctures were guided with ultrasound (US), and RSWT was delivered at 2 Hz (2000 shock waves; 0.26 mJ/mm2) once a week for 3 weeks. The COMB group received three weekly rounds of RSWT after a single US-guided needle puncture. The primary outcome was the pain visual analog scale (VAS), and secondary outcomes were the Constant scores, 36-Item Short-Form Health Survey, and range of motion. RESULTS: A within-group comparison at 3 months revealed significant improvements in the pain VAS (p< 0.05, during activity) and Constant (p< 0.05) scores, but between-group comparisons revealed no statistically significant differences in the pain VAS (p> 0.05) or Constant (p= 0.089) scores. Only improvement differences in role-emotional (SF-36; p= 0.01) and active external rotation (p= 0.035) were determined over time, which favored the USNP and COMB groups. CONCLUSIONS: Although no significant differences were observed among the groups in the treatment of calcific tendinitis of the shoulder, more satisfactory outcomes were noted in the USNP and COMB groups than in the RSWT group. Larger samples, longer follow-up times, and other treatment protocols are suggested for future studies.

The effect of giving verbal feedback during neck stabilisation exercise as an addition to physical therapy in patients with chronic neck pain: A randomised controlled trial.

OBJECTIVES: To study the addition of feedback-guided neck strength home exercise to physical therapy as an enhanced rehabilitation programme in the treatment of patients with chronic neck pain. DESIGN: A prospective randomised controlled trial. SETTING: Rehabilitation department of an academic hospital. SUBJECTS: Patients with chronic neck pain. INTERVENTIONS: The patients in both groups received supervised physical therapy sessions 3 times a week for 12 weeks. Patients in Group A (N = 38) used the neck strengthening exerciser device for 20 min daily at home for 6 weeks and patients in Group B (N = 20) performed 20 min of daily regular neck exercise at home for 6 weeks. OUTCOME MEASURES: Neck disability index, pain visual analogue scale, active range of motion of the neck, Patient Global Assessment and patient evaluation of treatment effect. All subjects were assessed at baseline as well as at 6- and 12-week follow-ups. RESULTS: At the 6-week follow-up, Group A exhibited significantly greater improvements (P < 0.05) in pain Visual Analogue Scale (Group A: 2.97 ± 1.57; Group B: 4.20 ± 1.82), neck disability index (Group A: 13.95 ± 8.07; Group B: 20.07 ± 9.14) and active cervical extension (Group A: 65.26 ± 12.76; Group B: 51.45 ± 11.78). At 12-week follow-up, Group A also exhibited significantly greater active cervical extension (Group A: 67.74 ± 11.94; Group B: 53.85 ± 14.09; P < 0.05). CONCLUSION: Adding neck strengthening exerciser home training to physical therapy was demonstrated to be more effective than physical therapy alone for patients with chronic neck pain.

Comparison of the corticosteroid injection and hyaluronate in the treatment of chronic subacromial bursitis: A randomized controlled trial.

OBJECTIVE: To analyse the effectiveness of corticosteroid (CS) and hyaluronic acid (HA) subacromial - subdeltoid (SASD) injection compared with normal saline (NS) in patients with chronic subacromial bursitis (CSB). DESIGN: A prospective three-arm double-blinded randomised controlled trial. SETTING: Rehabilitation department of two teaching hospitals. SUBJECTS: Patients with CSB (N = 186) divided into CS (N = 68), HA (N = 60), and NS (N = 58) groups. INTERVENTIONS: Three SASD injections under ultrasound guidance: group A, 20 mg of triamcinolone; group B, 2.5 mL of HA; and group C, 2.5 mL of NS. OUTCOME MEASURES: The primary outcome measures were the pain visual analogue scale (VAS) score at eight weeks. The secondary outcomes were scores on the Shoulder Pain and Disability Index (SPADI) and Shoulder Disability Questionnaire. RESULTS: At eight weeks, the pain VAS scores during activity were 2.56 ± 2.29, 3.65 ± 2.50, and 4.71 ± 2.83 in the CS, HA, and NS groups, respectively (CS vs NS, P < 0.001; HA vs NS, P = 0.013; CS vs HA, P = 0.010). SPADI scores were 40.83 ± 21.75, 36.92 ± 22.78, and 33.35 ± 23.38 in the CS, HA, and NS groups, respectively (CS vs NS, P < 0.001; HA vs NS, P = 0.197; CS vs HA, P = 0.004). CONCLUSION: Ultrasound-guided corticosteroid injection into the subacromial - subdeltoid bursa was proven to be effective and superior to hyaluronic acid and normal saline injection for treating CSB. Hyaluronic acid injection was only marginally more effective than normal saline injection.Trial Registration: ClinicalTrials.gov: NCT02702206.

Validity of Cyriax's Functional Examination for Diagnosing Shoulder Pain: A Diagnostic Accuracy Study.

OBJECTIVE: The purpose of this study was to compare the diagnostic accuracy of lesion localization between Cyriax's functional examination and ultrasonography in participants with and without shoulder pain. METHODS: A total of 206 adults aged 20 years and older with or without shoulder pain were included. All participants received Cyriax's functional examination by the first blinded physiatrist. Within a week, ultrasonography was performed by another blinded specialist. The diagnoses made by both methods, respectively, were compared finally. Sensitivity, specificity, and positive and negative predictive values were evaluated for the diagnosis of shoulder lesions between Cyriax's functional examination and ultrasonography. RESULTS: There was no significant difference between the 2 groups regarding age, sex, and body mass index. Moderate to high sensitivity (74.1%, 76.5%, and 66.7%) and high specificity (93.0%, 99.5%, and 99.0%) were in supraspinatus, subscapularis, and infraspinatus lesions, respectively. For the subacromial-subdeltoid bursitis, high sensitivity (90.4%) and moderate to high specificity (70.3%) was found. In contrast, low sensitivity (15.0%) and high specificity (100.0%) were found in the biceps lesions. CONCLUSION: In this study, we found that Cyriax's functional examination had high sensitivity in detecting subacromial-subdeltoid bursitis and high specificity in rotator cuff lesion.

Comparison Between Corticosteroid and Lidocaine Injection in the Treatment of Tennis Elbow: A Randomized, Double-Blinded, Controlled Trial.

OBJECTIVE: The aim of the study was to compare the effects of corticosteroid injection with lidocaine injection in treating tennis elbow. DESIGN: It is a prospective, double-blinded, randomized controlled trial. Patients with tennis elbow for more than 1 mo were recruited from a hospital-based rehabilitation outpatient clinic. A total of 70 patients were recruited, and 61 patients completed the study. Patients received an injection of either 10 mg (1 ml) of triamcinolone (corticosteroid group, n = 30) or 1 ml of 1% lidocaine (lidocaine group, n = 31). All of the outcome measures were evaluated before the intervention and at 2 wks and 2 mos after treatment. RESULTS: No significant group differences were observed between the corticosteroid and lidocaine groups regarding Patient-Rated Tennis Elbow Evaluation, Disability of the Arm, Shoulder, and Hand, visual analog scale for pain, and grip strength at baseline and at 2 wks and 2 mos after treatment (P > 0.05). However, within-group comparison showed significant improvement after injection with regard to Patient-Rated Tennis Elbow Evaluation, Disability of the Arm, Shoulder, and Hand, visual analog scale for pain, and grip strength in both groups (P > 0.05). CONCLUSIONS: No differences in the short-term outcomes were found between lidocaine and corticosteroid injection in a small sample of people with tennis elbow with mean duration of 3.8 mos.

Ultrasound-guided perineural injection with platelet-rich plasma improved the neurophysiological parameters of carpal tunnel syndrome: A case report.

Carpal tunnel syndrome (CTS) is a common and sometimes challenging condition, which causes pain; paresthesia; tingling of the thumb, index and long fingers; and even thenar weakness in the hands. The effectiveness of corticosteroid injections seems to be transient, and there is a lack of information around long-term effects in previous studies. In recent years, platelet-rich plasma (PRP) has proven to bean alternative as it encourages tissue regeneration. We hereby describe a patient with CTS showing significant improvements in electrophysiological parameters after receiving PRP injections. The results revealed significant improvements in the distal motor and sensory latencies as well as the sensory nerve action potential and compound muscle action potential amplitudes of the both median nerves. In summary, if patients are refractory to conservative treatments-such as splinting, oral medication, and corticosteroid injection-PRP may be used as an alternative before surgical intervention.

Ultrasound-Guided Musculocutaneous Nerve Block in Postherpetic Neuralgia.

Postherpetic neuralgia is a common and challenging complication of herpes zoster infection, particularly in older people. In recent decades, first-line treatments, including oral or topical medication, have become well established. However, few studies have reported the efficacy of interventional procedures for the treatment of postherpetic neuralgia. Here, the authors present a case of intractable postherpetic neuralgia treated with musculocutaneous peripheral nerve block under ultrasound guidance. Symptoms remained controlled at 1 mo follow-up. Ultrasound can be readily applied to improve the accuracy and efficiency of peripheral nerve block as it is currently widely used to evaluate the musculoskeletal system in clinical settings.
