ABSTRACT

Background: This study is to compare the efficacy of short-axis hydrodissection with long-axis hydrodissection for patients with mild-to-moderate carpal tunnel syndrome (CTS). Methods: Forty-seven patients with mild-to-moderate CTS were enrolled in a prospective, randomized, single-blinded, controlled trial (6 months follow-up). With ultrasound guidance, patients in both groups (short-axis or long-axis groups) were injected with normal saline (5 mL per session). Assessments were performed before and 2 weeks after the injection, as well as at 1, 3, and 6 months post-intervention. The primary outcome measure was the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) score and secondary outcomes included the cross-sectional area of the median nerve and electrophysiological studies. Results: Forty-four patients (21 wrists in the short-axis group and 23 wrists in the long-axis group) completed the study. Compared with the baseline, both groups showed improved BCTQ and cross-sectional area at all follow-up assessments (p<0.05). The short-axis group was not more effective except significant improvements in BCTQ-severity and BCTQ-function 1 month post-injection compared to the long-axis group (p = 0.031 and p = 0.023, respectively). Conclusions: Both short- and long-axis hydrodissection were effective for patients with mild-to-moderate CTS and the short-axis approach was not more effective than long-axis injection. Further studies with larger sample sizes, multiple injections, and larger injection volume are encouraged in the future.

ABSTRACT

Background: Perineural injection therapy with 5% dextrose water (D5W) is a potential and innovative treatment with long-term efficacy for carpal tunnel syndrome (CTS). However, the prognostic factors of this management are lacking; hence, the aim of this retrospective study was to identify the prognostic factors of D5W perineural injection therapy for mild-to-moderate CTS. Methods: A total of 52 patients (52 wrists) diagnosed with mild-to-moderate CTS and treated with a single ultrasound-guided 5cc D5W perineural injection were retrospectively reviewed. Patient-reported injection outcomes (visual analog scale, VAS) at 6 months post-injection were categorized into two groups; (1) Good outcome, when symptom relief ≥50% compared to pre-injection and (2) Poor outcome, when symptom relief < 50% compared to pre-injection. Significant variables between groups were entered into a binary logistic regression with forward stepwise regression to determine the prognostic factors for these outcomes. Results: The treatment outcome was significantly related to body height and sensory nerve conduction velocity (SNCV) (159.1 ± 1.0 vs. 155.0 ± 1.8, p=0.04; 33.6 ± 0.8 vs. 28.3 ± 1.2, p=0.001, good vs. poor outcomes). However, only SNCV remained significantly correlated with the outcomes after conducting stepwise logistic regression (ORs: 1.201; 95% CI 1.05-1.38; p=0.01). Conclusions: SNCV was found to be a significant prognostic factor of treatment outcome for patients with mild-to-moderate CTS 6 months after a D5W perineural injection.

ABSTRACT

OBJECTIVES: To investigate the effect of hyaluronic acid (HA) in patients diagnosed with mild or moderate carpal tunnel syndrome (CTS). DESIGN: A prospective randomized, double-blinded control study with 6 months of follow-up. SETTING: Rehabilitation outpatient clinic of one single medical center. SUBJECTS: Thirty-five participants with mild or moderate CTS. METHODS: Participants were enrolled and randomly assigned to HA or control groups. The HA group received one ultrasound-guided perineural injection of 2.5 mL HA while the control group received 2.5 mL normal saline injection through in-plane, long-axis approach to separate the median nerve from the flexor retinaculum via nerve hydrodissection. Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were the primary outcome, while secondary outcomes included the numeric rating scale (NRS), electrophysiological domains, and the cross-sectional area of the median nerve. The assessment was conducted prior to injection and during the second week and 1-, 3-, and 6-months post-injection. RESULTS: Thirty-two patients (17 wrists in HA group and 15 wrists in control group) completed the study. Compared with the control group, the HA group did not show significantly superior outcomes, except in BCTQ and NRS at the second week post-injection (all P < .0125). CONCLUSIONS: A single ultrasound guided perineural HA injection may have short-term therapeutic efficacy for mild or moderate CTS; however, the 2-weeks superior efficacy was not beneficial for chronic neuropathy. Further studies with larger sample sizes are required to verify its therapeutic efficacy.

ABSTRACT

OBJECTIVE: To assess the therapeutic effect of platelet-rich plasma (PRP) for moderate-to-severe carpal tunnel syndrome (CTS). DESIGN: A prospective, randomized, double-blinded, controlled trial (1-year follow-up). SETTING: Outpatient of local medical center settings. PARTICIPANTS: Patients (N=26) who were diagnosed with bilateral moderate-to-severe CTS (total 52 wrists) were included. For each patient, one wrist was randomized into either the PRP or control group and the contralateral wrist of the same patient was allocated to another group. Twenty-four patients were included in the final data analysis. INTERVENTIONS: The wrists in the PRP group received a single ultrasound-guided dose of PRP injection (3.5mL), and the control group received a single ultrasound-guided injection with normal saline (3.5mL). MAIN OUTCOME MEASURES: The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were used as the primary outcome. Secondary outcomes encompassed the cross-sectional area of the median nerve and electrophysiological study. Assessments were conducted prior to injection and 1, 3, 6, and 12 months postinjection. RESULTS: Compared to the control group, the PRP group exhibited significant improvements in BCTQ severity scores at all time points, BCTQ functional scores at the sixth month, and cross-sectional area at the 12th month postinjection (P<.0125). CONCLUSIONS: A single dose of ultrasound-guided perineural PRP injection can provide therapeutic effect for 1 year postinjection.

ABSTRACT

OBJECTIVE: To assess the effects of perineural corticosteroid and 5% dextrose water (D5W) injections in patients with mild to moderate ulnar neuropathy at the elbow (UNE). DESIGN: Prospective, randomized, double-blind, controlled trial (6-month follow-up). SETTING: Outpatients of local medical center settings. PARTICIPANTS: Patients (N=36) with mild to moderate UNE were randomized, and 33 participants were included in the final data analysis. INTERVENTIONS: Patients were administered a single perineural injection with 5 mL D5W and 3 mL corticosteroid (triamcinolone acetonide, 10mg/mL) mixed with 2 mL normal saline under ultrasound guidance in the dextrose and steroid groups, respectively. MAIN OUTCOME MEASURES: The visual analog scale digital pain or paresthesia/dysesthesia score was the primary outcome. The secondary outcomes were the Disabilities of the Arm, Shoulder, and Hand questionnaire, motor nerve conduction velocity, and cross-sectional area (CSA) of the ulnar nerve. The measurement assessment was conducted before and 1, 3, 4, and 6 months after injection. RESULTS: Thirty-three patients completed the study. Both injections were found to be equally effective at most measurement points, although the dextrose group experienced larger reductions in symptom severity and CSA of the ulnar nerve from the third month onward. CONCLUSIONS: We suggest D5W as a more suitable injectate for perineural injection in patients with UNE.

ABSTRACT

OBJECTIVES: To evaluate the combination effect of platelet-rich plasma (PRP) and extracorporeal shock wave therapy (ESWT) for moderate carpal tunnel syndrome (CTS), compared with PRP alone. DESIGN: A randomized, double-blinded, placebo-controlled trial. SETTING: A single medical center in Taiwan. PATIENTS: Patients diagnosed with moderate CTS. INTERVENTIONS: All subjects were administered one dose of ultrasound-guided PRP injection at baseline. After two weeks, one session of rESWT was completed in the intervention group, whereas the control group received one session of sham rESWT. Evaluations were performed at baseline and one, three, and six months post-PRP injection. OUTCOME MEASURES: The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was measured as the primary outcome. Electrophysiological study and cross-sectional area (CSA) of the median nerve were used as secondary outcomes. RESULTS: All 40 enrolled subjects (male/female: 4/36) completed the study, resulting in an analysis of 32 wrists per group (total: N = 64 wrists). Compared with the control group, the intervention group did not show statistically significantly superior outcomes, except in BCTQs at one month (mean change ± SE = -11.47 ± 1.18 vs -7.06 ± 1.26, P = 0.013) and distal motor latency at three months (mean change ± SE = -0.59 ± 0.09 vs -0.30 ± 0.09, P = 0.031). CONCLUSIONS: Combined PRP and one-session rESWT was not superior to PRP alone in treating moderate CTS. Further studies with multiple sessions of ESWT and longer follow-up periods are needed to verify the clinical efficacy of ESWT.

ABSTRACT

Recent studies demonstrated the utility of perineural injection with platelet-rich plasma (PRP) and 5% dextrose (D5W) as novel strategies for treatment of carpal tunnel syndrome (CTS). The present study comprised a prospective, randomized, single-blind, head-to head comparative trial to compare the 6-month outcome of perineural injection with PRP or D5W in patients with moderate CTS. Fifty-two patients with unilateral moderate CTS were enrolled and randomized into two groups: The PRP group received a single 3-cc perineural injection of PRP under ultrasound guidance, and dextrose group received a single 3-cc perineural injection of D5W under ultrasound guidance. The Boston Carpal Tunnel Syndrome Questionnaire score was used as the primary outcome. Secondary outcomes included cross-sectional area (CSA) of the median nerve and electrophysiological assessments. Evaluations were performed at baseline and at 1, 3, and 6 months postinjection. All patients (26 patients per group) completed the study. Compared with the dextrose group, the PRP group demonstrated significant reductions in Boston Carpal Tunnel Syndrome Questionnaire function at 3 months (p = .044), distal motor latency at 6 months (p = .028), and CSA at 3 and 6 months (p = .010 and.018, respectively). A single perineural injection of PRP reduced the CSA of the median nerve more effectively than injection of D5W at 3 and 6 months postinjection for patients with moderate CTS.

ABSTRACT

INTRODUCTION: In this study we explored the efficacy of nerve hydrodissection for mild-to-moderate carpal tunnel syndrome (CTS). METHODS: Thirty-four participants were randomly assigned to an intervention group or a control group. One 5-ml dose of normal saline was injected into the intracarpal and subcutaneous regions in subjects of both groups, respectively. The primary outcome measure was the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) score. Secondary outcomes were cross-sectional area of the median nerve and electrophysiological studies. Assessments were performed before the injection and at 1, 2, 3, and 6 months postintervention. RESULTS: Compared with the control group, the intervention group showed significantly greater improvement at the second and third posttreatment months according to BCTQ severity score and at all time-points for cross-sectional area of the median nerve (P < 0.01). DISCUSSION: Our study demonstrates the therapeutic effects of nerve hydrodissection for mild-to-moderate CTS. Muscle Nerve 59:174-180, 2019.

ABSTRACT

Although neuralgic amyotrophy (NA) has occasionally been reported to be associated with reactivated herpes zoster, their associated risk remains unknown. The aim of this study was to assess the risk of developing NA following preceding herpes zoster. The authors used the National Health Insurance Research Database of Taiwan to select 41,548 patients with newly diagnosed herpes zoster during the period 2000 to 2010 and randomly extracted 166,192 matched control subjects. All participants in the study and control groups were followed for 3 months after the diagnosis to identify those who developed NA. Cox proportional hazards regression analyses were performed to evaluate the subsequent risk of NA. Twenty-one subjects from the group with herpes zoster (0.05%) developed NA over the 3-month period and 46 from the group without herpes zoster (0.03%). The patients with herpes zoster had a higher risk of developing NA (adjusted hazard ratio = 1.408, 95% confidence interval = 1.013-2.319, P = 0.030). In the patients with herpes zoster, female sex, age ≥ 65, hepatitis E virus (HEV), and having had a recent infectious event including pneumonia and influenza were risk factors for developing NA (adjusted HR 2.746, 1.998, 2.735, 2.016, and 1.718, respectively, all P < 0.05). Patients with herpes zoster attack have a higher risk of developing NA over a 3-month period after diagnosis, especially those who are female, age ≥ 65, HEV, or have experienced a recent infectious event or pneumonia and influenza.

ABSTRACT

OBJECTIVE: Perineural injection with 5% dextrose (D5W) is a novel strategy in the treatment of carpal tunnel syndrome (CTS). In contrast, perineural injection with corticosteroid has been used for decades for treating CTS, but possible neurotoxicity has been a major concern. No studies investigating the comparative effects have been published so far. The authors performed a prospective, randomized, double-blinded, head-to-head comparative trial to compare these two approaches for patients having mild-to-moderate CTS. METHODS: Fifty-four participants with mild-to-moderate CTS were randomly divided into dextrose and steroid groups. The patients were administered 1 session of perineural injection with 5ml D5W (dextrose group) or 3ml triamcinolone acetonide mixed with 2ml normal saline (steroid group), under ultrasound guidance. A visual analog scale was assigned to assess the primary outcome. The secondary outcomes were assessed using the Boston Carpal Tunnel Syndrome Questionnaire, cross-sectional area of the median nerve, and electrophysiological studies. The assessment was performed prior to injection and 1, 3, 4, and 6 months postinjection. RESULTS: All patients (27 wrists per group) completed the study. Compared with the steroid group, the dextrose group exhibited a significant reduction in pain and disability through the 4th to the 6th month (p < 0.01). INTERPRETATION: Our study demonstrates that perineural injection of D5W is more beneficial than that of corticosteroid in patients with mild-to-moderate CTS at 4 to 6 months postinjection.

ABSTRACT

BACKGROUND AND OBJECTIVE: Parkinson's disease (PD) is a neurodegenerative condition characterized by motor dysfunction and various types of non-motor impairments. The reaction time and movement time are reported to become more severe delayed in worse PD patients. Most tools for evaluating motor impairment are limited by relying on subjective observations and being qualitative in design. The aim of this study was to investigate trunk rolling performance in PD patients by using a recently developed system to detect turning in bed. METHODS: The study included 20 PD patients and 42 healthy controls. A mattress mobility detection system was employed for quantitative measurements. Each test session consisted of subjects starting by lying in a supine position on a bed and rolling 10 times onto their left side and 10 times onto their right side. Strain gauges mounted under the feet of the bed recorded changes in the center of pressure (CoP). RESULTS: For turning back, the patients compared with the controls had significantly longer movement time (P = 0.017), longer time to peak counteraction (P = 0.001), larger ratio of peak counteraction to movement time (P = 0.006), shorter CoP displacement (P < 0.0001), slower turning speed (P = 0.000), weaker peak counteraction (P = 0.013), and smaller ratio of peak counteraction to weight (P = 0.032). Results for turning over were similar except there was no significant difference in the ratio of peak counteraction to weight. CONCLUSIONS: The mattress mobility detection system was useful for objectively assessing trunk rolling performance of PD patients. Improved assessment of trunk function in PD patients could lead to better treatments and improved rehabilitation procedures.

ABSTRACT

RATIONALE: Perineural injection with dextrose could be a novel intervention for peripheral entrapment neuropathy. However, this intervention has not been reported for treating radial nerve palsy (RNP). Here, we present a case with RNP having outstanding improvement after 2 sessions of ultrasound-guided perineural injection with 5% dextrose (D5W). PATIENT CONCERNS: A 62-year-old woman presented with difficulty and weakness in extension of her left wrist and fingers after she slept with the arm compressed against her body. DIAGNOSES: On the basis of the findings of electrophysiological study and ultrasonography, the RNP with axonal injury was diagnosed. INTERVENTIONS: Initially, the patient received 2-months conservative treatments without any improvement. Two sessions of ultrasound-guided perineural injection with total 15cc D5W with an interval of 1 month were performed 2 months after symptom onset. OUTCOMES: A noteworthy improvement in sensory and motor functions was observed after ultrasound-guided perineural injection with D5W. LESSONS: This case shows that ultrasound-guided perineural injection with D5W may be an effective and novel intervention for RNP.

ABSTRACT

Metatarsalgia is characterized by pain in the forefoot, which is associated with increased stress over the metatarsal head region. Despite the availability of a variety of conservative or surgical treatments for this condition, a few cases have demonstrated relapse or poor response to treatment. Pulsed radiofrequency (PRF) can provide pain relief in patients with diverse chronic conditions without causing neural injury. Recently, studies have shown that ultrasound-guided PRF may be beneficial for adhesive capsulitis, carpal tunnel syndrome, tarsal tunnel syndrome, and recalcitrant plantar fasciitis. Here, we describe a successful case of significant pain relief achieved by using ultrasound-guided PRF targeting the posterior tibial nerve (PTN) at the ankle of a 67-year-old woman with recalcitrant metatarsalgia. Ten minutes after ultrasound-guided PRF was applied at the PTN, the patient reported decreased pain (from 8 to 3 on a visual analogue scale) and did not exhibit any particular side effects. Three months after PRF application, the patient's visual analogue scale score remained more than 50% below the baseline, and she did not need additional conservative treatment during the follow-up period. To the best of our knowledge, we present the first case report using ultrasound-guided PRF at the PTN for treatment of recalcitrant metatarsalgia. We hypothesize that ultrasound-guided PRF at the PTN may be a potentially novel approach for treating recalcitrant metatarsalgia.

ABSTRACT

OBJECTIVE: To assess the 6-month effectiveness of ultrasound-guided perineural injection therapy (PIT) using 5% dextrose (D5W) in patients with mild-to-moderate carpal tunnel syndrome (CTS). PATIENTS AND METHODS: A prospective, randomized, placebo-controlled, and double-blind study was conducted between May 1, 2016, through March 30, 2017. A total of 49 participants diagnosed with mild-to-moderate CTS were randomized into D5W and control groups. Participants in the D5W group received 1 session of ultrasound-guided PIT with 5 cc of D5W, and the control group received PIT with normal saline. The visual analog scale measured pain as a primary outcome. Secondary outcomes were Boston Carpal Tunnel Syndrome Questionnaire scores, the cross-sectional area of the median nerve, and electrophysiological measurement results. Assessment was performed before injection and at 1, 3, and 6 months post-injection. RESULTS: All patients (data from 30 wrists in each group) completed the study. Compared with the control group, at all post-injection time points, the D5W group had a significant reduction in pain and disability, improvement on electrophysiological response measures, and decreased cross-sectional area of the median nerve. CONCLUSION: Our study reveals that ultrasound-guided PIT with D5W is an effective treatment for patients with mild-to-moderate CTS. TRIAL REGISTRATION: www.ClinicalTrials.gov: NCT02809261.

ABSTRACT

Recently, a few small reports with short follow-up period have shown clinical benefits of platelet-rich plasma (PRP) for peripheral neuropathy including one pilot study and one small, non-randomized trial in patients with carpal tunnel syndrome (CTS). Therefore, we conducted a randomized, single-blind, controlled trial to assess the 6-month effect of PRP in patients with CTS. Sixty patients with unilateral mild-to-moderate CTS were randomized into two groups of 30, namely the PRP and control groups. In the PRP group, patients were injected with one dose of 3 mL of PRP using ultrasound guidance and the control group received a night splint through the study period. The primary outcome measure was the visual analog scale (VAS) and secondary outcome measures included the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) score, the cross-sectional area (CSA) of the median nerve (MN), electrophysiological findings of the MN, and finger pinch strength. The evaluation was performed before treatment and at 1, 3, and 6 months post-injection. The PRP group exhibited a significant reduction in the VAS score, BCTQ score, and CSA of MN compared to the those of control group 6 months post-treatment (p < 0.05). Our study demonstrates that PRP is a safe modality that effectively relieves pain and improves disability in the patients with CTS.

ABSTRACT

Amniotic fluid stem cells (AFSCs) are multipotent stem cells that may be used in transplantation medicine. In this study, AFSCs established from amniocentesis were characterized on the basis of surface marker expression and differentiation potential. To further investigate the properties of AFSCs for translational applications, we examined the cell surface expression of human leukocyte antigens (HLA) of these cells and estimated the therapeutic effect of AFSCs in parkinsonian rats. The expression profiles of HLA-II and transcription factors were compared between AFSCs and bone marrow-derived mesenchymal stem cells (BMMSCs) following treatment with γ-IFN. We found that stimulation of AFSCs with γ-IFN prompted only a slight increase in the expression of HLA-Ia and HLA-E, and the rare HLA-II expression could also be observed in most AFSCs samples. Consequently, the expression of CIITA and RFX5 was weakly induced by γ-IFN stimulation of AFSCs compared to that of BMMSCs. In the transplantation test, Sprague Dawley rats with 6-hydroxydopamine lesioning of the substantia nigra were used as a parkinsonian-animal model. Following the negative γ-IFN response AFSCs injection, apomorphine-induced rotation was reduced by 75% in AFSCs engrafted parkinsonian rats but was increased by 53% in the control group after 12-weeks post-transplantation. The implanted AFSCs were viable, and were able to migrate into the brain's circuitry and express specific proteins of dopamine neurons, such as tyrosine hydroxylase and dopamine transporter. In conclusion, the relative insensitivity AFSCs to γ-IFN implies that AFSCs might have immune-tolerance in γ-IFN inflammatory conditions. Furthermore, the effective improvement of AFSCs transplantation for apomorphine-induced rotation paves the way for the clinical application in parkinsonian therapy.
