Wee TC, Simon NG. Asymptomatic common extensor tendon pathology in patients with carpal tunnel syndrome. Muscle Nerve 2021; 64:64-69. [PMID: 33847378 DOI: 10.1002/mus.27252] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 04/07/2021] [Accepted: 04/09/2021] [Indexed: 12/19/2022]
Abstract
INTRODUCTION/AIMS Carpal tunnel syndrome (CTS) and lateral epicondylitis are both highly prevalent conditions. Our objective was to determine the prevalence of B-mode ultrasound abnormalities of the common extensor tendon (CET) in patients with CTS and establish the relationship between CET stiffness, as measured by shear wave elastography (SWE) and CTS severity. METHODS Patients without symptoms or signs of lateral epicondylitis were recruited from referrals to a neurophysiology laboratory for possible CTS. These patients were examined for clinical features of CTS before undergoing electrodiagnostic testing followed by an ultrasound examination, consisting of B-mode, power Doppler, and SWE. RESULTS Thirty-nine limbs with clinically diagnosed CTS and 20 control limbs were included. Of the CTS limbs, 61.5% had sonographically abnormal CET compared with 35% of the controls. The mean CET sonographic abnormality score was higher in CTS patients compared with controls (P = .006). CTS patients with sonographically abnormal CET had more severe CTS by electrophysiological criteria. The mean CET stiffness in CTS patients was lower than in controls (P = .033). DISCUSSION Sonographic abnormalities of the CET are common in CTS patients with no clinical evidence of lateral epicondylitis and may relate to common pathogenetic mechanisms. These findings suggest that isolated ultrasound abnormalities in the CET are not diagnostically useful in patients presenting with upper limb pain unless there are clinical features of lateral epicondylitis.

Abstract
OBJECTIVES To compare the diagnostic performance between strain elastography and shear wave elastography (SWE) for the diagnosis of carpal tunnel syndrome (CTS). METHODS Between July 2018 and June 2019, 66 consecutive patients with 95 imaged wrists underwent wrist ultrasound, including grayscale ultrasound, strain elastography, and SWE, because of the suspicion of CTS. During wrist ultrasound, the cross-sectional area (CSA), strain ratio, elasticity, and shear wave velocity of each median nerve were measured at the proximal carpal bone level (scaphoid to pisiform). The variables were compared between the normal and CTS groups by using the independent t test, and subgroup analyses were performed using one-way analysis of variance. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of each variable. RESULTS CSA, elasticity, and shear wave velocity showed significant intergroup differences (P < 0.001, P < 0.001, and P = 0.002, respectively). However, the strain ratio showed no statistically significant intergroup difference (P = 0.639). In the subgroup analyses, elasticity showed significantly higher values in the severe group than in the mild and moderate groups (P < 0.001 and P = 0.001, respectively). Other parameters showed no significant differences among the different subgroups. The areas under the ROC curve were 0.823 for CSA, 0.772 for elasticity, and 0.779 for shear wave velocity. The differences in the areas under the ROC curve among CSA, elasticity, and shear wave velocity were not statistically significant (all P > 0.05). CONCLUSIONS SWE has a good diagnostic value in CTS. In particular, elasticity can discriminate the severe group from the other groups.

Efficacy of kinesio taping on hand functioning in patients with mild carpal tunnel syndrome. A double-blind randomized controlled trial. J Hand Ther 2021; 35:605-612. [PMID: 34256988 DOI: 10.1016/j.jht.2021.04.011] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 03/23/2021] [Accepted: 04/05/2021] [Indexed: 02/03/2023]
Abstract
STUDY DESIGN Double-blind randomized controlled trial. INTRODUCTION Carpal tunnel syndrome (CTS) is a common mononeuropathy that causes pain and disability in the affected hand. Kinesio taping (KT) has been recently proposed as a promising conservative approach in CTS patients. PURPOSE OF THE STUDY To investigate the effectiveness of KT compared to a sham taping on symptoms and hand function in patients affected by mild CTS. METHODS Patients affected by mild CTS with symptoms for at least 8 weeks were enrolled and randomly allocated into two groups: KT group, according to the technique proposed by Kase plus specific exercises; control group, undergoing a sham taping plus specific exercise. All patients performed 2 sessions/week for 5 weeks of exercises of mobilization of fingers and carpal joint. At the baseline, after 5 weeks (T1), and after 6 months (T2), a physician unaware of patients' allocation assessed the Boston Carpal Tunnel Questionnaire (BCTQ) symptom (BCTQ-S) and functional (BCTQ-F) subscales. RESULTS Forty-two patients (mean age:54.3 ± 15.0 y) were randomly allocated into KT (n = 21) and control group (n = 21). At T1, in both groups we found a significant improvement in hand function and symptoms, as showed by BCTQ-F (KT:4.2 ± 0.7 vs 3.0 ± 0.6, P < .001; sham: 2.2 ± 0.3 vs 1.7 ± 0.3, P = .012) and by BCTQ-S (KT: 2.2 ± 0.3 vs 1.7 ± 0.3, P < .001; sham: 2.3 ± 0.4 vs 1.9 ± 0.5, P = .007). At T2, only in the KT group there was a significant difference in both sub-items of primary outcome. There were significantly better results in the KT group at T1 and T2. DISCUSSION The present study showed that KT compared to a sham taping might be more effective in reducing perceived symptoms in mild CTS patients, reporting a clinically significant difference. CONCLUSION KT might be considered as an effective technique combined to rehabilitative treatment in terms of hand function and symptoms in patients affected by mild CTS.

Abstract
OBJECTIVE Previous studies reported variable sensitivity and specificity of the Phalen test. We investigated whether a timed Phalen's test (TPT) could predict abnormal nerve conduction studies (NCS) results in carpal tunnel syndrome (CTS). METHODS Patients with CTS were consecutively recruited. A neurologist confirmed the clinical diagnosis of CTS and recorded the TPT before NCS were performed. Another neurologist, blinded to the TPT, graded the severity of NCS. The TPT sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. RESULTS In total, 403 patients with 706 hands were recruited and diagnosed with CTS; 465 hands had positive TPT, and 611 hands showed abnormal NCS results. A positive TPT at ≤ 10 s had a specificity of 96.8% and a PPV of 96.6% in predicting abnormal NCS. The sensitivity and NPV of TPT were insignificant. DISCUSSION A positive TPT at ≤ 10 s can be useful in predicting NCS abnormalities in patients with CTS.

[PMID: 32317146 PMCID: PMC7572818 DOI: 10.1016/j.jos.2020.03.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 02/03/2020] [Accepted: 03/05/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Carpal Tunnel Syndrome (CTS) is an idiopathic fibrotic disorder. Fibrosis in the subsynovial connective tissues (SSCT) of CTS and many other fibrotic diseases is mediated by Transforming growth factor β (TGF-β). Recently monocyte chemoattractant protein-1 (MCP-1) a cytokine involved in cellular recruitment has been suggested to regulate TGF-β activity. It is related to the onset of diseases which are caused by fibrosis, such as idiopathic pulmonary fibrosis, renal fibrosis, and systemic scleroderma. In this study, we evaluated the effect of the MCP-1 synthesis inhibitor, Bindarit, on primary cultures of fibroblasts from the SSCT of five CTS patients. METHODS Fibroblasts were treated with Bindarit (10 μM, 50 μM, 100 μM, or 300 μM). Responses to inhibitors were evaluated by regulation of CTS fibrosis-associated genes, fibrosis gene array and Smad luciferase reporter assay. We also assessed the combination effect of Bindarit and SD208, a TGF-β receptor type 1 inhibitor on TGF-β signaling. RESULTS Collagen type III A1 (Col3), connective tissue growth factor (CTGF), and SERPINE1 expression were significantly down-regulated by Bindarit (300 μM) compared to vehicle control. In the fibrosis array, expression of inhibin beta E chain precursor (INHBE), beta actin (ACTB), endothelin 1 (EDN1) and hypoxanthine phosphoribosyltransferase 1 (HPRT1) were significantly down-regulated, and integrin beta-3 (ITGB3) was significantly up-regulated by Bindarit (300 μM). Smad signal transduction activation was significantly down-regulated by Bindarit (300 μM) and/or SD208 (1 μM) with TGF-β1 compared to vehicle control with TGF-β1. CONCLUSIONS These results suggest that Bindarit in combination with SD208 may be beneficial as medical therapy for the SSCT fibrosis associated with CTS.

Abstract
Background: The utility of nerve conduction studies (NCS) for diagnosis of carpal tunnel syndrome (CTS) has continued to be a subject of debate. Proponents of NCS assume a high sensitivity and specificity; however, many are unaware of the actual literature on this topic and the cutoff values commonly used for diagnosis. The purpose of this systematic review of the literature is to report the sensitivity and specificity of NCS for diagnosis of CTS in various studies. Methods: A literature review of PubMed and EMBASE databases was performed for all articles on NCS for diagnosis of CTS. The outcome of interest was the sensitivity and/or specificity of the NCS distal motor latency (DML) or distal sensory latency (DSL) cutoff value used to diagnose CTS in each study. Results: A total of 3066 total articles were screened and 21 were included in the review after assessment by two independent reviewers. The mean cut-off value for DSL was 3.37 ms (range 2.8-4 ms) and the mean cutoff value for DML was 4.28 ms (range 3.8-4.6 ms). Weighted mean DSL sensitivity was 73.4% and weighted mean DSL specificity was 93.6%. Weighted mean DML sensitivity was 56.2% and weighted mean DML specificity was 95.8%. Conclusions: There is significant variation in the cutoff values used for both DSL and DML. The wide range of cut-off values makes it difficult to interpret the literature, and there is a lack of high-quality studies with control groups using a priori cut-off values for diagnosis.

Abstract
Objective: Our aim was to evaluate High Frequency Ultrasonography as a tool for diagnosis in patients withcarpal tunnel syndrome in comparison with electrophysiological study. Methods: Thirty- one patients [56 hands] with CTS and twenty-five asymptomatic controls [50 hands] were assessed and underwent ultrasonography of the wrists and electrophysiological testing. Data from the patient and the control groups was compared for both the investigations to determine the CTS and the grade of severity. Results: There was a high degree of correlation between the conduction abnormalities of the median nerve as detected by electrodiagnostic tests, historic and objective scale [Hi-Ob] and the measurement of the cross-sectional area of the nerve by US (P < 0.05). A cut-off point of 0.88 mm2 for the mean cross-sectional area of the median nerve was found to be the upper limit for normal values. Compared to Ultrasonography which found one hand negative, six hands (10%) were negative on the electrophysiological tests. Using critical CSA value of 1.0 mm2 in these CTS cases by US with sensitivity and specificity of 100% and 88%. Based on the results of this study, ultrasonography of wrist is another useful tool along with nerve conduction studies as per sensitivity and specificity patterns found in our study in diagnosis of carpal tunnel syndrome. Conclusion: High-frequency US examination of the median nerve and measurement of its cross-sectional area can be strongly considered as useful diagnostic diagnostic modality for the evaluation of CTS along with nerve conduction studies. In addition to its high diagnostic accuracy it is able to define the cause of nerve compression, aids treatment planning and provides a reliable method to follow response to therapy.

Abstract
OBJECTIVE Routine nerve conduction study (NCS) parameters are less sensitive in the early stage of carpal tunnel syndrome (CTS). Recently, some studies have shown that prolonged distal sensory nerve action potential (DSNAP) duration may be a more sensitive technique for the diagnosis of demyelinating peripheral neuropathies. We aimed to evaluate the sensitivity of median DSNAP duration in patients with CTS. METHODS DSNAP duration and routine NCS data of the median nerve were retrospectively collected in 173 CTS patients, 73 controls, and 78 cervical radiculopathy patients. RESULTS Prolonged median DSNAP durations were found in 22 patients (22/35, 63%) and 36 patients (36/54, 67%) in the minimal and mild CTS groups respectively, which was more sensitive than routine NCS parameters. The percentage of patients demonstrating abnormalities in median NCS was significantly increased from 80% to 92% with the addition of DSNAP duration. CONCLUSION Our results demonstrate the electrodiagnostic value of median DSNAP duration for the diagnosis of CTS, especially in early cases.

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
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
Entrapment neuropathies cover a wide range of isolated nerve injuries along the course of the upper and lower extremity nerves. Electrodiagnostic (EDX) testing is usually an essential part of the evaluation of entrapment neuropathies, and examinations for the most common entrapment neuropathies, carpal tunnel syndrome and ulnar neuropathy at the elbow, constitute a significant part of the daily work in EDX laboratories. Despite this, guidelines for EDX testing are generally sparse or do not exist for entrapment neuropathies, whereas a wide variety of different techniques are available to the clinical neurophysiologist. This study reviews the existing, more or less, detailed EDX criteria or practice parameters that are suggested by consensus groups in peer-reviewed journals for the most common entrapment neuropathies: carpal tunnel syndrome, ulnar neuropathy at the elbow, common peroneal (fibular) neuropathy at the fibular head, and tibial neuropathy at the tarsal tunnel. It is concluded that future research is needed to develop and refine EDX guidelines in entrapment neuropathies.

Abstract
Objectives
This study aims to identify the optimal follow-up method for evaluation of the surgical outcome for carpal tunnel syndrome (CTS). Patients and methods
Between January 2006 and December 2010, 61 hands of a total of 46 patients (7 males, 39 females; mean age 56.0±10.4 years; range, 20 to 71 years) with a diagnosis of CTS were retrospectively analyzed. All operations were performed by a single surgeon with a mini-incision distal to the transverse carpal ligament. At a mean follow-up of seven years after surgery, electromyography (EMG) was repeated for all patients. The Boston Carpal Tunnel Questionnaire (BCTQ), Boston Symptom Severity Scale, Boston Functional Status Scale, palmar pinch strength, grip strength, and EMG of the patients were compared before and after surgery. Results
The mean follow-up was 84±10 (range, 72 to 104) months. There were significant improvements in the Boston Symptom and Functional Scale scores postoperatively, as well as in the grip and pinch strength. After surgery, EMG findings improved in 83.6% of the patients. However, there was no significant correlation between pre- and postoperative Boston Symptom Severity Scale scores, functional status, pinch and grip strengths, and pre- and postoperative EMG results. Conclusion Our study results demonstrate that the symptom severity and functional status scores of the BCTQ are favorable, and this tool is reliable and easy-to-apply for the diagnosis and follow-up of CTS surgeries.

Abstract
Background Dexterity impairments caused by carpal tunnel syndrome (CTS) make working and daily activities challenging. We aimed to investigate: i) the relationship between dexterity and nerve conduction studies (NCS) in workers with classic symptoms presentation; ii) the ability of the Functional Dexterity Test (FDT) to discriminate different levels of CTS severity as classified by NCS; iii) the diagnostic accuracy of a clinical battery composed of the FDT, Phalen’s test and Tinel’s sign. Methods In a convenience sample of individuals diagnosed with CTS, we correlated FDT net scores with the NCS-based classification by means of Spearman’s (rho) test. Discriminative ability of the FDT was assessed by ANOVA, and a ROC curve determined cutoff thresholds. Sensitivity, specificity, and likelihood ratios (LRs) were used to investigate the diagnostic accuracy of the clinical battery. Results Data from 180 hands were collected. The FDT was significantly correlated (rho = 0.25, p < 0.001) with NCS. The FDT was able to discriminate subjects with severe/extreme NCS findings, and two thresholds (0.29–0.36) were identified. Adding the FDT to the provocative tests improved the overall diagnostic accuracy (specificity: 0.97, CI95% 0.83–0.99; LR+: 14.49, CI95% 2.09–100.53). Conclusions Sensorimotor impairments related to CTS can affect hand dexterity. The FDT discriminated patients with severe NCS involvement. Positive results on the clinical battery (Phalen, Tinel, and FDT) could help to confirm the CTS diagnosis, showing a very high specificity and LR+. On the contrary, the low sensitivity is not able to rule out CTS in individuals with negative results.

Abstract
BACKGROUND Sex difference is known to be a risk factor of carpal tunnel syndrome. However, sex differences with regard to the clinical presentation of carpal tunnel syndrome have not received much attention. Thus, this study aimed to detect any difference in the characteristics of carpal tunnel syndrome between male and female and thereby add new insights into disease prevention. METHODS A total of 647 patients (male 193 hands and female 454 hands) with carpal tunnel syndrome who underwent endoscopic or open carpal tunnel release were retrospectively reviewed. The average age at time of surgery was 66 years. Clinical and electrophysiological data of all patients were collected. Six medical conditions, including trigger finger, diabetes mellitus, hemodialysis, hyperlipidemia, hypertension, and obesity were also investigated. RESULTS A significant difference was found in the distribution of comorbidities between the male and female groups. Particularly, the prevalence of diabetes mellitus, hemodialysis, and hypertension were significantly higher in the male group than in the female group. Meanwhile, the presence of thenar muscle atrophy was significantly higher in the female group than in the male group. CONCLUSIONS Women are more likely to experience carpal tunnel syndrome even though they have no comorbidities. We suggest that carpal tunnel syndrome especially in male patients may be reduced by early intervention for diabetes mellitus. Prospective studies are needed to validate the causal relationship between diabetes mellitus and carpal tunnel syndrome.

Abstract
Background: Carpal tunnel syndrome (CTS) is the most common focal mononeuropathy in the general population, and obesity is one of its established independent risk factors The prevalence of obesity in CTS patients and its association with CTS severity are yet to be fully studied among Tanzanians. In this study, we determined the frequency of obesity in patients with CTS and its relationship with the electrophysiological severity of CTS in a Tanzanian private tertiary level hospital. Methods: This is a retrospective observational and analytical study of patients referred for electrodiagnostic (EDX) evaluation of suspected CTS at the clinical neurophysiology laboratory of the Aga Khan Hospital, Dar es Salaam, Tanzania. All EDX studies done for CTS indications between August 1, 2017, and December 31, 2019, were reviewed. The frequency of CTS patients with obesity (body mass index >30 kg/m2) and overweight (25.0-29.9 kg/m2) was determined. Next, we explored the relationship between obesity and the electrophysiologic severity of CTS. Results: One-hundred nine hands were studied. The prevalence of obesity was 50.5% and overweight was 31.2%. Females were significantly more obese than males (P = 0.001). Many of the EDX parameters that defined CTS, including prolonged median nerve sensory and distal motor latencies as well as sensory conduction velocity, were significantly more abnormal in the obese when compared to the nonobese patients. On univariate analysis, severe CTS (stage 5) was commoner among nonobese patients (P = 0.031), while moderate CTS (stage3) was more prevalent among obese patients (P < 0.001). Multivariate regression analysis, however, revealed no effect of obesity on CTS severity (P = 0.490). Conclusion: Obesity and overweight are prevalent among this cohort with CTS, but did not predict severe CTS. The use of other indices of adiposity may show a trend.

Abstract
Background Diagnostic delay of hereditary transthyretin amyloidosis (ATTRv, v for variant) prevents timely treatment and, therefore, concurs to the mortality of the disease. The aim of the present study was to explore with nerve ultrasound (US) possible red flags for early diagnosis in ATTRv patients with carpal tunnel syndrome (CTS) and/or polyneuropathy and in pre-symptomatic carriers. Methods Patients and pre-symptomatic carriers with a TTR gene mutation were enrolled from seven Italian centers. Severity of CTS was assessed with neurophysiology and clinical evaluation. Median nerve cross-section area (CSA) was measured with US in ATTRv carriers with CTS (TTR-CTS). One thousand one hundred ninety-six idiopathic CTS were used as controls. Nerve US was also performed in several nerve trunks (median, ulnar, radial, brachial plexi, tibial, peroneal, sciatic, sural) in ATTRv patients with polyneuropathy and in pre-symptomatic carriers. Results Sixty-two subjects (34 men, 28 women, mean age 59.8 years ± 12) with TTR gene mutation were recruited. With regard to CTS, while in idiopathic CTS there was a direct correlation between CTS severity and median nerve CSA (r = 0.55, p < 0.01), in the subgroup of TTR-CTS subjects (16 subjects, 5 with bilateral CTS) CSA did not significantly correlate with CTS severity (r = − 0.473). ATTRv patients with polyneuropathy showed larger CSA than pre-symptomatic carriers in several nerve sites, more pronounced at brachial plexi (p < 0.001). Conclusions The present study identifies nerve morphological US patterns that may help in the early diagnosis (morpho-functional dissociation of median nerve in CTS) and monitoring of pre-symptomatic TTR carriers (larger nerve CSA at proximal nerve sites, especially at brachial plexi).

Abstract
Abstract
Background
Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy. Typical symptoms and signs include numbness, tingling, pain, or burning sensation in the digits supplied by the median nerve and/or nocturnal paresthesia. Treatments of CTS range from conservative measures to surgical decompression of the median nerve.
Results
The PRP group showed a statistically significant reduction in the visual analog scale, Boston Carpal Tunnel Syndrome Questionnaire, for the severity and the functional capacity scores, and cross-sectional area of the median nerve compared to those of control group 3 months post-treatment (p < 0.05).
Conclusions
Platelet-rich plasma injection in CTS relieves pain and symptom severity and improves functional status but not significantly improve the electrophysiological parameters.

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
RATIONALE In the medical field, the use of 3-dimensional (3D) printing is increasing explosively and it is especially widespread in the clinical application of fabricating orthosis. Advantages of 3D-printed orthosis compared to conventional ones include its lower cost, easier modification, and faster fabrication. The 3D-printing technique makes it possible for physicians to easily create individual-tailored products. Recently, many kinds of orthosis through 3D printing have been studied and used. The knee orthosis, ankle-foot orthosis, wrist orthosis, hand orthosis, and foot orthotics are examples used in the rehabilitation fields of orthotics. We reported 3 cases of 3D-printed orthoses in patients with peripheral nerve injuries. PATIENTS CONCERNS In spite of the rapid development of the clinical use of 3D printing, to our knowledge, its application to patients with peripheral nerve injuries has not yet been reported. Two patients suffered from upper limb problems and 1 patient had a foot drop associated with peripheral nerve injury. DIAGNOSIS Three patients diagnosed with median neuropathy, ulnar neuropathy, and right lower lumbar radiculopathy, respectively, by electromyography. INTERVENTIONS Herein we present 3 case reports of patients with peripheral nerve injuries whose orthotic needs were fulfilled with the application of 3D-printed wrist orthosis and ankle-foot orthosis. OUTCOMES For hand function evaluation, we assessed the Jebsen-Taylor hand function test. Grasp and pinch powers were assessed by a hand dynamometer before and after orthosis application. For lower limb functional evaluation, we used a 6-minute walking test and modified Emory Functional Ambulation Profile for ambulatory function. LESSONS The 3D-printed orthosis could help functional improvement in patients with peripheral nerve injuries.

Abstract
This prospective single-centre study describes the functional outcomes, satisfaction and health-related quality of life after open revision carpal tunnel decompression for recurrent carpal tunnel syndrome. The QuickDASH, patient satisfaction and EuroQol-5 dimensions questionnaires were collected preoperatively and postoperatively over a 5-year period (2013-2018). The median time to revision was 13.3 years (range 3.9-35.4 years; interquartile range 7.2-15.9 years). Outcomes were available for 14 hands in 13 patients at a mean of 20 months after revision surgery. The mean preoperative and postoperative QuickDASH scores were 55 and 29, respectively, and the mean improvement in QuickDASH was 26. The mean improvement in EuroQol-5 dimensions score was 0.1, and 13 of the 14 patients were satisfied. The net promoter score was 85. This study confirms that patients undergoing revision open carpal tunnel decompression for recurrent carpal tunnel syndrome experience a significant improvement in function and health-related quality of life. Level of evidence: IV.

Abstract
Introduction: Carpal tunnel syndrome is one of the most common peripheral neuropathies. Only a few studies evaluate the efficacy of “nutraceuticals” on peripheral nerves and neuropathic pain. The aim of the present investigation is to evaluate the role of Alfa-Lipoic Acid-R (ALA-R) on clinical and functional outcomes in patients affected by mild to moderate carpal tunnel syndrome. Material and Methods: The present investigation is a prospective randomised controlled open label study, performed at our Hand Surgery Department (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome) from October 2018 to March 2019. The enrolled patients were divided in two groups: Group A (ALA-R 600mg once day for 60 days) and Group B (control Group, no drug administration). Results: 134 patients (74 F, 60 M) met the inclusion and exclusion criteria. In Group A, there was a statistically significant pain reduction compared to the control Group. Using the Boston Carpal Tunnel Questionnaire, there were no significant improvements in the other symptoms and function. Conclusion: ALA-R full dose administration for two months leads to positive short term results in terms of symptoms and function improvement, even if the surgical carpal tunnel release remains the treatment of choice.

Efficacy of platelet-rich plasma as an adjuvant to surgical carpal ligament release: a prospective, randomized controlled clinical trial. Sci Rep 2020; 10:2085. [PMID: 32034241 PMCID: PMC7005701 DOI: 10.1038/s41598-020-59113-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 01/24/2020] [Indexed: 01/04/2023] Open
Abstract
The purpose of this study is to evaluate the efficiency of local platelet-rich plasma (PRP) injection as an adjuvant treatment after carpal ligament release. We conducted a prospective randomized, triple-blinded, controlled trial. Fifty participants with mild to extreme carpal tunnel syndrome (CTS) were randomly assigned either to the PRP (n = 25) or the platelet-poor plasma (PPP, n = 25) group. After performing open surgical release of the carpal ligament, the inside of the carpal tunnel was irrigated with 3 mL of PRP or PPP according to each participant’s group allocation. The primary outcome was hand grip strength (HGS). Secondary outcomes were the time taken off work after surgery (in days) and scores on the Wong–Baker Faces Scale, Boston Carpal Tunnel Questionnaire, and Southampton Wound Assessment Scale. We evaluated patients before treatment and at 6-weeks. As expected, the pain levels, symptom severity, and functional status improved in all the patients after surgery. However, intragroup analysis revealed that only the participants in the PRP group had regained their pre-operative HGS levels at 6-weeks follow-up. These findings indicate that PRP is an effective adjuvant treatment in patients with mild to severe CTS who require surgery.

Abstract
BACKGROUND Compressive neuropathy is a recurring and challenging disease for patients, regardless of medical or surgical treatment. Neuropathological severity is associated with the force of mechanical compression. Available animal models do not address mechanical issues with reproducible outcomes. We used a chronic constriction injury model to analyze tension-controlled compressive neuropathy and achieve reproducible functional outcomes. NEW METHOD We refined a modified animal model for chronic constriction nerve injury under controllable compressive tensile strength to target the unilateral sciatic nerve of adult rats. Sensory outcomes were evaluated using the Von Frey test. Muscle atrophy and nerve degeneration were analyzed, including markers of neural degeneration, neuroinflammation, and neuropathic pain in the affected nerve. RESULTS The compressive force significantly affected the neuropathological severity of sensory dysfunction and muscle atrophy. Greater mechanical forces (i.e., tight-knot) contributed to muscle atrophy and hypoesthesia. Low forces (i.e., loose-knot) induced mechanical allodynia with better residual muscle weight. Well-controlled loose knotting can avoid myelin degradation while lessening neuroinflammation and macrophage infiltration. Neuropathic pain was enhanced with increased nociceptive pain markers expression within the affected nerve. Comparison with Existing Method(s): Our chronic constriction injury model, unlike previous models, controls the ligation forces applied for different levels of injury. CONCLUSION The functional influences of different compressive forces recapitulate the diverse clinical symptoms involved in clinical compressive neuropathy. This controllable and reproducible model of compressive neuropathy revealed the underlying molecular mechanisms of neural degeneration and inflammation. It will lead to the future development of translational therapeutics for neuropathic pain and nerve regeneration.

Abstract
OBJECTIVE To describe morphological changes associated with degeneration and regeneration of large fibers in the skin using a model of chronic compression of the median nerve. METHODS We studied cutaneous innervation in 30 patients with chronic compression of the median nerve at the wrist. Before surgery, we assessed the symptom severity and performed neurography, quantitative sensory testing, and analysis of nerve morphology and morphometry in skin biopsies from the third digit fingertip. Fifteen patients repeated all tests 12 months after the surgery. Thirty age- and sex-matched healthy subjects were included in the study. RESULTS Clinical and neurophysiological basal assessment showed a moderate involvement of the median nerve. Quantitative sensory testing showed abnormal findings. The density of intraepidermal nerve fibers and intrapapillary myelinated endings was reduced. Myelinated fibers showed caliber reduction and nodal elongation. Meissner corpuscles had normal density but were located deeper in the dermis and their capsule appeared partially empty. During follow-up, patients exhibited a positive clinical and neurophysiological outcome. Quantitative sensory testing improved. Intraepidermal nerve fibers and intrapapillary myelinated endings remained unchanged, but the caliber of intrapapillary myelinated endings was increased. The neural component of the Meissner corpuscle filled the capsule of the mechanoreceptors that remained deeper in the dermis. The position of vasoactive intestinal peptide-immunoreactive fibers was more superficial compared to the basal assessment and controls. INTERPRETATION We recognized and quantified the pathological changes associated with nerve degeneration and regeneration in skin and proposed new parameters that may increase the diagnostic yield of skin biopsy in clinical practice.

Lidocaine With Epinephrine Versus Bupivacaine With Epinephrine as Local Anesthetic Agents in Wide-Awake Hand Surgery: A Pilot Outcome Study of Patient’s Pain Perception. JOURNAL OF HAND SURGERY GLOBAL ONLINE 2020; 2:1-6.

Abstract
Purpose Wide-awake local anesthesia hand surgery has many advantages over other forms of anesthesia, including faster recovery, lower cost, and improved patient safety; however, few studies compare postoperative pain and analgesic consumption after long- and short-acting anesthetics. This is important because surgeons seek to minimize opioid consumption during the opioid epidemic. Methods This was a double-blinded, prospective, randomized, parallel design pilot study. We randomized 61 patients to receive carpal tunnel surgery with a short-lasting regional anesthetic (lidocaine, 29 patients) or a long-lasting one (bupivacaine, 32 patients). Primary outcomes were pain levels over the first and second 24 hours. Secondary outcomes were postoperative consumption of acetaminophen and opioids over the first and second 12 hours after surgery. Results Pain intensity and acetaminophen consumption were significantly less in the bupivacaine group over the first 24 and 12 hours after surgery, respectively. The bupivacaine group consumed less opioids in the first 12 hours and delayed consumption of the first medication after surgery, but these results were not statistically significant. There was no difference in pain intensity or analgesic consumption between 24 and 48 hours after surgery. Conclusions The use of a long-term anesthetic (bupivacaine) over a short-term one (lidocaine) in awake carpal tunnel release surgery decreases postoperative pain over the initial 12 hours after surgery and delays the initiation of analgesic consumption; however, this difference is small. The amount of opioid consumption was not significantly different between groups, but both groups consumed less than 10% of the prescribed opioids. It is important to reevaluate the need for opioids in minor hand surgery and favor the use of alternatives such as nonsteroidal anti-inflammatory drugs and acetaminophen. Type of study/level of evidence Therapeutic I.

Abstract
Background Carpal tunnel syndrome (CTS) is the commonest entrapment neuropathy. The aim of this study was to assess the accuracy and validity of high resolution musculoskeletal ultrasound (US) in the diagnosis of CTS in the Saudi population. Methods Sixty patients were diagnosed clinically to have CTS involving 89 wrists that were confirmed by neurophysiologic studies. Each affected wrist was characterized as idiopathic or associated with either diabetes mellitus or hypothyroidism and were assigned a severity grade based on results of neurophysiologic studies. Seventy-six healthy wrists from fifty age, sex and BMI matched healthy subjects were included in the control group. High resolution ultrasound (US) was performed to assess median nerve cross sectional area distal (CSAd) at the entry to the carpal tunnel and proximally (CSAp) at the level of pronator quadratus muscle with a further calculation of their difference (ΔCSA) and their mean average or CSAd+CSAp/2 (CSApd). Results There was a significant difference between both groups regarding mean ± SD of CSAd, CSAp, ∆CSA, and CSApd (p = 0.0001). A positive significant correlation was also found between the CSAd, ∆ CSA and the CSApd measurements with neurophysiologic severity grade of CTS (P = 0.001). A ∆CSA threshold of 2.5 mm2 showed the highest sensitivity and specificity to diagnose CTS in Saudis. Conclusion High resolution ultrasound is a valid and accurate diagnostic modality in carpal tunnel syndrome and correlated to CTS severity. A ∆CSA greater than 2.5 mm2 is considered a valid diagnostic value for CTS in our Saudi population. CTS in our patients with diabetes tend to have greater median nerve US measurement values.

Abstract
The median and ulnar nerves can be recorded consecutively or simultaneously to diagnose carpal tunnel syndrome. Simultaneous and consecutive recording of the median and ulnar nerves sensory latency have a poor agreement. Technical variations can have diagnostic consequences.
Objective To assess if recording the sensory latencies of the median and ulnar nerves one-by-one (consecutive) or at the same time (simultaneous) in the ring-finger test for carpal tunnel syndrome (CTS) will show equivalent results or if it will lead to a different clinical classification of patients. Methods We assessed the limits of agreement between the simultaneous and the consecutive method based on the median- ulnar sensory latency difference derived by both methods in 80 subjects and compared the number of minimal CTS cases identified by the two methods. Results Limits of agreement ranged from −0.23 to 0.29 ms. A significantly higher proportion of subjects with minimal CTS (only detectable by using the comparison test) was found using the simultaneous method (n = 8 and 2, respectively; p = 0.03). Conclusion The two methods have a poor to moderate agreement as indicated by the range of the limits of agreement (0.5 ms). Significance Even small methodological changes to the ring-finger test can lead to results with different clinical meaning in the same individual and one should be aware of which method was used when interpreting results.

Abstract
The Boston Carpal Tunnel Questionnaire (BCTQ) is a scale that has been developed specifically for carpal tunnel syndrome (CTS). It consists of the Functional Status Scale (FSS) and the Symptom Severity Scale (SSS). It is the most widely used patient reported outcome measure in CTS and has been validated in many languages. Although already widely used, psychometric properties of the Dutch version of the BCTQ are yet unknown. The aim of this study was to assess the validity, reliability, responsiveness, and acceptability of the Dutch version. Moreover, this paper focuses the longitudinal validity (the use after an intervention) of the BCTQ, which has not been investigated before. A total of 180 patients completed the BCTQ in addition to a six-point Likert scale for perceived improvement, before and about 6–8 months after carpal tunnel release (CTR). Principal factor analysis revealed that the FSS is unidimensional, consisting of a single latent factor (“functionality”) and has a high internal consistency (Cronbach's α = 0.825). However, the SSS has three dimensions, which are all highly internally consistent: “daytime symptoms” (Cronbach's α = 0.805), “nighttime symptoms” (Cronbach's α = 0.835), and “operational capacity” (Cronbach's α = 0.723). Post-treatment, the FSS still consisted of one factor, but the SSS changed in dimensionality, as it had only two factors left post-treatment. The ΔFSS and ΔSSS had good correlation with the six-point Likert scale for perceived improvement (r = 0.524; p < 0.01 and r = 0.574; p < 0.01, respectively), a moderate correlation between FSS and pinch grip (r = 0.259; p < 0.01) was found, and a weak correlation between SSS and pinch grip (r = 0.231; p < 0.01) was found. Standard Response Mean for FSS and SSS was 0.76 and 1.49, respectively. Effect size was 0.92 and 1.96, respectively, both indicating a good responsiveness. Response rate was high (82–84%). We concluded that the Dutch version of the BCTQ has a proper reliability, validity, responsiveness, and acceptability to assess the symptom severity and functional disabilities of CTS patients. Because of multidimensionality, we would recommend to create sum scores of the four different dimensions instead of two. Caution is required when interpreting the results postoperatively, due to the insufficient longitudinal validity of the SSS.

Abstract
Carpal tunnel syndrome (CTS) is the most common mononeuropathy caused by entrapment of the median nerve at the wrist. Common treatment options for CTS include oral analgesics, splinting, hand therapy, local injections with steroids or surgery. OBJECTIVE The aim of the present study was to assess the short-term clinical and electrophysiological outcomes of local corticosteroid injection (LCI) in patients with symptomatic CTS. METHODS Electrophysiological parameters were evaluated before and three months after LCI. Moreover, the Numeric Rating Scale (NRS), the Boston Symptom Severity Scale (SSS) and the Functional Status Scale (FSS) were administered before and after the injection. A mixture of 1 mL (40 mg) of methylprednisolone and 1 mL of 0.5% bupivacaine were injected blindly on the volar side of the forearm between the tendons of the radial carpal flexor muscle and long palmar muscle. RESULTS A total of 25 patients (45 hands) were enrolled in the study. Twenty women and five men with a mean age of 49.28 ± 11.37 years were included. A statistically significant difference was noted for improvement of sensory conduction velocities, sensory peak latency, and motor distal latency (p = 0.001) after LCI. A significant difference was recorded between pre- and post-injection for NRS, SSS and FSS scores (p = 0.000). CONCLUSION Local corticosteroid injection for CTS provides a short-term improvement in neurophysiological and clinical outcomes such as pain intensity, symptom severity and functional ability.

Abstract
Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy. Its diagnosis is based on clinical symptoms and neurophysiological evaluation. Recently, ultrasonography has been introduced as a promising noninvasive diagnostic alternative. In this study, the authors compared ultrasonography with neurophysiological findings for the diagnosis of CTS in 96 patients/hands with clinical symptoms of CTS. The latency, amplitude, distance, and velocity of the median and ulnar nerves were measured. Needle electromyography was performed in the abductor pollicis brevis, in addition to muscles of the arm and forearm, to exclude proximal median nerve, brachial plexus, or radicular abnormalities. Ultrasonography was based on the morphologic/anatomic changes of the median nerve cross-sectional area in the sagittal plane of the wrist at the level of the pisiform bone, the changes of its regional echogenicity, and the identification of coexisting pathologies, such as tenosynovitis, space-occupying lesions, supplementary muscles, and vessels, that may provoke indirectly an increase of the pressure in the carpal tunnel. Eighty-seven (90%) of the 96 patients/hands with clinical symptoms of CTS showed positive findings in both ultrasonography and nerve conduction studies. Six (6%) patients showed positive findings only in nerve conduction studies, and 3 (3%) patients showed positive findings only in ultrasonography; the difference was not statistically significant. The sensitivity and the specificity of nerve conduction studies compared with ultrasonography was 97% and 89% compared with 94% and 55%, respectively. A positive correlation and proportional increase of the ultrasonography measurements compared with the increase of the nerve conduction studies severity was observed.

Abstract
One of the most common referrals to the electrodiagnostic (EDX) laboratory is to confirm a clinical impression of carpal tunnel syndrome (CTS). The EDX studies are valuable in localizing median nerve abnormalities to the wrist, grading its severity, and excluding other condition that can mimic or coexist with CTS. However, there are many clinical and EDX pitfalls that can lead to misdiagnosis. Careful clinical assessment and attention to technical factors and details of the EDX techniques are fundamental for the quality and accurate interpretation of the study. This review aims to discuss the clinical and the EDX approaches to the diagnosis of CTS with emphasis on the commonly encountered pitfalls.

Abstract
This chapter covers the electrodiagnostic (EDX) evaluation of upper extremity nerves and the brachial plexus. Carpal tunnel syndrome is the most common peripheral nerve disorder of the upper extremity. A number of techniques are used but there is no gold standard approach for its diagnosis. Needle EMG aids in the differentiation of proximal and distal median neuropathies. Ulnar neuropathy at the elbow and ulnar neuropathy at or distal to the wrist can be distinguished by EDX techniques. Radial neuropathy at the spiral groove has a specific EDX pattern. EDX assessment of proximal upper extremity nerve lesions such as brachial plexopathy is a valuable tool for exploring the diagnosis and differential diagnosis of this complex disorder.

Abstract
INTRODUCTION Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy that causes hand discomfort and work disability. Since no satisfactory conventional treatments for mild to moderate CTS exist, we apply complementary alternative medicine (CAM) to this problem. Laser acupuncture (LA), a new, non-invasive therapy which uses low-level-laser therapy (LLLT) in acupuncture could help to manage CTS. However, only one small randomized, double-blind and crossover trial had been conducted, which is not enough to provide an evidence-based assessment of the effects of LA on CTS. OBJECTIVES The aim of this study protocol is to investigate the efficacy of LA therapy on patients with mild to moderate CTS through sonography of the median nerve and offer clear parameters of LLLT. METHODS This study protocol is a prospective double-blind randomized controlled trial. Forty subjects aged 20 to 80 years old and diagnosed as having mild to moderate CTS will be randomly assigned to the intervention group (real LA, 3-sessions a week for 2 weeks) and control group (sham LA, 3-sessions a week for 2 weeks). All subjects will be asked to wear night splints as the fundamental management approach. The laser parameters will include a wavelength of 808 nm, power output of 300 mW and power density of 300 mW/mm, with ten seconds of treatment for each acupuncture point (PC4, PC6, PC7, PC8, LI4, LI10, LI11, HT3, HT7, and LU10). Sham LA treatment will be applied without any laser power output. The primary outcome will be based the Boston Carpal Tunnel Syndrome Questionnaire and secondary outcomes included a visual analog scale, cross sectional area of median nerve by sonography and electrophysiological test before interventions and after 2, 4, 8, 12 weeks postintervention. TRIAL REGISTRATION ClinicalTrials.gov (Identifier: NCT03580265).

Abstract
OBJECTIVE To use anatomic measurements on magnetic resonance imaging (MRI) and ultrasonography (USG) in diagnosing and grading carpal tunnel syndrome (CTS) using nerve conduction studies (NCS) as the gold standard. MATERIAL AND METHODS In this prospective study, 26 patients with CTS (45 wrists; 22 female and 4 male patients; mean ± SD age of 49.42 + 14.47 years) and 19 age and sex matched healthy volunteers (32 wrists; 15 female and 4 male volunteers, mean ± SD age of 42.52 + 10.85 years) underwent MRI and USG. Cross-sectional area (CA) of median nerve was measured using free hand ROI at four levels: hamate hook (H0), pisiform bone (PI0), 1 cm proximal (PI1) and 2 cm proximal to PI0 (PI2). Relative median nerve signal intensity (MNSI) was calculated as ratio of median nerve signal intensity with hypothenar muscle signal intensity. Flexor retinacular bowing was calculated at hamate hook level. Echogenicity and Power Doppler vascularity of median nerve were assessed on USG. Independent t-test, chi square test and receiver operating characteristic curve analysis were used as appropriate. RESULTS On USG, CA measured at PI0 (95% confidence interval of 0.872-0.987) and retinacular bowing (0.816-0.912), while, on MRI, CA at PI1 (0.874-0.997) were most useful in diagnosing CTS based on the ROC and Zombie plot analysis. Area under curves for CA measurements on USG and MRI were not significantly different. CA at PI1 on MRI (0.752-0.965) was significantly different between minimal to moderate CTS and severe to extreme CTS groups (on NCS). CONCLUSION CA of median nerve is the most useful parameter to diagnose and grade CTS and USG and MRI are comparable for measurements. Increased retinacular bowing on USG and hypoechogenicity of median nerve increase the diagnostic confidence while MRI helps in picking up important associated conditions.

Abstract
BACKGROUND Endoscopic carpal tunnel release (ECTR) has been gradually adopted for the treatment of severe carpal tunnel syndrome (CTS). However, perioperative assessment of neuroanatomical parameters of median nerve, which are important determinant of median nerve recovery, has rarely been reported. This one-year prospective study aimed to investigate the natural history of the neuroanatomical morphology of the median nerve after ECTR in severe CTS patients by high-frequency ultrasonography and assess the ability of neuroanatomical measures to quantify morphological recovery of the median nerve after ECTR. METHODS This study recruited 31 patients (44 wrists) with a definitive diagnosis of severe CTS and underwent ECTR operation. The edema length (EL) of median nerve from the inlet of the carpal tunnel to the proximal wrist was detected on long axis imaging plane and the anteroposterior diameter (D) and cross-sectional area (CSA) at the inlet of the carpal tunnel on short axis imaging plane were detected by high frequency ultrasound. All these metrics were detected at 3 days before surgery and at the 2nd week, 4th week, 3rd month, 6th month and 12th month after surgery separately. RESULTS There was no significant difference of each parameter between the 2-week postoperative (1.914 ± 0.598 cm in EL, 0.258 ± 0.039 cm in D and 0.138 ± 0.015 cm2 in CSA) and 3-days preoperative time points (P-EL =0.250; P-D = 0.125; P-CSA =0.712). From the fourth week to the third month after surgery, the parameters quickly improved. The EL (0.715 ± 0.209 cm), D (0.225 ± 0.017 cm) and CSA (0.117 ± 0.012 cm2) at the 3- month postoperative time points were more reduced than at the fourth week after surgery (P-EL < 0.001; P-D = 0.038; P-CSA =0.014). Thereafter, the neurological anatomy parameters recovered slowly. By the 12-month postoperative time points, the three parameters were neuroanatomically close to normal. Compared to the control group in D (0.213 ± 0.005 cm), there was no difference at the 12-month time point (0.214 ± 0.009 cm, P = 0.939). However, the difference in EL (0.098 ± 0.030 cm vs. 0.016 ± 0.011 cm) and CSA (0.103 ± 0.008 cm2 vs. 0.073 ± 0.005 cm2) between patients and healthy volunteers at the 12-month time point still existed (P-EL < 0.001; P-CSA < 0.001). CONCLUSIONS Neuroanatomical parameters were gradually improved after ECTR surgery. The best time for US follow up is at 3-month postoperative time point for patients who do not show clinical improvement, since at this time the change is the greatest for most CTS patients. This study has been registered in Chinese Clinical Trial Registry: ChiCTR-ROC-17014068 (retrospectively registered 20-12-2017).

Abstract
INTRODUCTION The objective of this study was to determine whether patients with carpal tunnel syndrome (CTS) manifest changes in early-stage motor function and to investigate the utility of a gyrosensor for quantitative evaluation of motor function. METHODS Angular velocity signal was measured during finger tapping in 52 patients with mild-to-moderate CTS and 45 controls. Four finger-tapping performance (FTP) values-root-mean-squared (RMS) velocity, RMS angle, peak power, and total power-were derived from the signal. RESULTS All FTP values were significantly lower in patients with CTS than in controls (P = 0.001 or P < 0.001). There were no significant differences between the mild and moderate CTS subgroups. DISCUSSION FTP measurement with a gyrosensor represents a valuable tool for the evaluation of median nerve motor function in patients with CTS. It facilitates the detection of subclinical motor dysfunction in patients with early stage CTS. Muscle Nerve 59:465-469, 2019.

Abstract
Background: Carpal tunnel syndrome (CTS) is one of the most common focal entrapment neuropathies. Although the exact etiology remains unclear, high-pressure-related intracarpal tunnel compression of the median nerve (MN), progressing ischemia, and mechanical strangulation are common mechanisms. The therapeutic managements for CTS depend on the disease severity, varying from a conservative treatment to surgical interventions. Conservative treatment is helpful for most of the patients with mild-to-moderate CTS. Hydrodissection is a minimally invasive procedure of injecting solutions into some anatomical spaces to facilitate dissection and adhesiolysis. Steroids as an anti-inflammatory drugs are used to treat chronic pain conditions. Hyaluronidase as an adhesolysis agent can also be used for epidural injections with local anesthetics (LAs) and steroids for control of chronic back pain. Aim of the Study: This study was carried out to compare the efficacy of hyaluronidase versus dexamethasone as adjuvants to the mixture of LAs in ultrasound (US)-guided hydrodissection of the median nerve in mild to moderate cases of carpal tunnel syndrome. Settings and Design: This study was a prospective randomized controlled double-blinded clinical study. Methods: 40 patients aged from 20 to 60 years old with clinical, electrophysiologic, and ultrasonographic evidence of mild to moderate CTS were included in this study. Each patient was assessed at the baseline (prior to injection) and at 1 week, 1 month, 3 months, and 6 months intervals after injection: (1) The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) which is a frequently used patient-based questionnaire for measurement of CTS. primary outcome. (2) Median motor and sensory nerve conduction studies (NCS) secondary outcome. (3) Median nerve ultrasonography. The ultrasound examination included measurement of the median nerve cross-sectional area (CSA) at the distal wrist crease (DWC). Also, the median nerve echogenicity, mobility, and vascularity at the DWC were assessed by US. Secondary outcome. All outcome assessments were assessed by single investigator who was blinded to the study details. All patients received US guided hydrodissection of the median nerve at the distal wrist crease. The selected patients were randomly allocated into 2 groups containing 20 patients each according to the study drugs; Group (D) received 5 mL (3 mL plain bupivacaine 0.5% and 2 mL (8 mg) dexamethasone), and Group (H) received 5 mL (3 mL plain bupivacaine 0.5% and 2 mL normal saline containing 300 international units (IU) hyaluronidase. Ultrasound-guided intracarpal injection using ultrasonography (Sono Scape A5; Shinzhen, China) with a 10-18-MHZ linear array transducer was performed by the same physician who was not aware of study groups, the MN was observed at the inlet of the carpal tunnel, 3 ml of solution was injected via the in-plane ulnar approach, to detach the MN from the transverse carpal ligament and an additional 2 ml was injected to separate the MN from underlying flexor tendons. All patients were observed for 30 minutes post injection for possible side effects before discharge. Normally distributed numerical data are presented as mean ± standard deviation, and differences between the groups were compared using the independent Student's t-test. Chi-square test was used for categorical data. Intragroup data at different follow up time points were evaluated using paired Student's t-test. All statistical tests were two-tailed, with P < 0.05 being considered statistically significant. Results: The demographic data of the patients in both groups were statistically insignificant (P-value >0.05). In the pre-injection time, there were no statistically significant differences between both groups as regards BCTQ (SSS, FSS), electrophysiological studies (SNCV, DML), and sonographic data (CSA, echogenicity score, mobility score, and vascularity score). The comparison between both groups showed that measured parameters as regards BCTQ (SSS, FSS), electrophysiological studies (SNCV, DML), and sonographic data (CSA, echogenicity score, mobility score, and vascularity score) were significantly improved in group H compared with group D in the follow up periods at 1 week, 1 month, 3 months and 6 months post-injection (P-value <0.05). The comparison within each group showed that in group D, the measured parameters; BCTQ (SSS, FSS), electrophysiological studies (SNCV, DML), and sonographic data (CSA, echogenicity score, mobility score, and vascularity score) were statistically significantly improved at 1 week, 1 month and 3 months follow up post-injection times but they were not significantly improved at 6 months post-injection time compared with the pre-injection data (P-value >0.05). While in group H, these measured parameters were statistically significantly improved in the all follow up post-injection times; at 1 week, 1 month, 3 months and even at 6 months periods compared with the baseline pre-injection data (P-value < 0.05). Conclusion: In this study, it was concluded that MN hydrodissction using hyaluronidase (as an adhesolysis agent) significantly improved patients with mild to moderate CTS compared to steroid (as an anti-inflammatory agents) hydrodissection of MN as regards BCTQ (SSS, FSS), electrophysiological studies (SNCV, DML), and sonographic data (CSA, echogenicity score, mobility score, and vascularity score) not only at 1 week, 1 month and 3 months follow up post-injection times but these parameters were also significantly improved at 6 months post-injection time in bupivacaine- hyaluronidase hydrodissection group compared to bupivacaine-steroid hydrodissection group.

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
Background Thumb opposition is vital for hand function and involves pronation and palmar abduction. The improvement of pronation is often used as one of the evaluation items of the opponensplasty method for severe carpal tunnel syndrome. However, most of the studies used substitution evaluation methods for measurement of the pronation angle. Thus, there is still no appropriate method for measuring thumb pronation angle accurately in carpal tunnel syndrome patients. In recent reports, a wearable gyroscope was used to evaluate upper extremity motions and it can be possibly used for accurate measurement of the thumb pronation angle along the three-dimensionally moving bone axis. Thus, we investigated the reliability of measuring thumb pronation using a gyroscope and evaluated whether this method can be used to detect opposition impairment. Methods The participants were volunteers with unaffected upper limbs (32 hands) and patients with carpal tunnel syndrome (27 hands). The pronation and palmar abduction angles during opposition movements were measured using a three-axis gyroscope that included a three-axis accelerometer. The gyroscope was fixed onto the first metacarpal bone and the thumb phalanx. Results The pronation and palmar abduction angles of the metacarpal bone and the palmar abduction angles of the phalanx significantly decreased in the carpal tunnel syndrome group. The pronation angle of the metacarpal bone during opposition movement peaked later than the palmar abduction angle in all hands. Conclusions We were able to measure the thumb pronation and palmar abduction angles using the three-axis gyroscope, and this tool was able to detect impairments of thumb opposition due to carpal tunnel syndrome. This could be a tool for measuring thumb and finger angles and for detecting impairments caused by various diseases.

Abstract
INTRODUCTION The purpose of this study was to determine the correlation between a measure of physical performance, a measure of physiology and a measure of anatomy in the setting of carpal tunnel syndrome (CTS). METHODS A retrospective review of 215 consecutive patients with suspected CTS was conducted. All patients were evaluated with static 2-point discrimination (2PD), ultrasound (US) measurement of the median nerve cross-sectional area (CSA), and nerve conduction studies (NCS). Correlations between 2PD and US and NCS parameters were calculated. The ability of US/NCS to predict 2PD was evaluated. RESULTS Analysis failed to prove a statistically significant correlation between 2PD and median nerve CSA. A weak correlation was detected between 2PD and NCS parameters. When 2PD was used as a reference standard, NCS parameters combined had the greatest sensitivity, followed by US. CONCLUSIONS Currently used diagnostic tests (NCS and US) correlate poorly with 2PD.

Abstract
PURPOSE To evaluate if there is a place for ultrasonography (US) and ultrasonographic elastography (UE) in the diagnosis and follow up of carpal tunnel syndrome treatment. MATERIALS AND METHODS The study was performed on 25 patients (study group) and 17 healthy volunteers (control group). Measured US and UE criteria were median nerve area (MNA), proximal median nerve area (pMNA), difference between MNA and pMNA (dMNA) and strain values of carpal tunnel content (CTC) and median nerve (MN). Patients in the study group were also evaluated using the Boston questionnaire, Visual Analogue Scale (VAS) and nerve conduction studies. Thirty-three wrists in 23 patients received steroid injections on the same day. Patients were re-evaluated 6 weeks after steroid injection. To establish a cut off value for MNA, ROC Curve analysis was used. RESULTS Mean MNA and dMNA values in the control group were significantly lower than in the study group (7.33 ± 1.31 vs. 15.44 ± 5.10; p=<0.05 and 1.58 ± 0.75 vs. 8.91 ± 4.93; p = 0.00 respectively). Median nerve and CTC strain indices were significantly higher in the control group (p = 0.00 and p = 0.036). Decrease in MNA and dMNA values after treatment was meaningful (p = 0.00). While there was no significant change in MN elasticity, mean CTC strain index of the study group (4.680 ± 1.664) decreased significantly after treatment (3.621 ± 1.054 p = 0.002). This decrease in the CTC index was more pronounced in patients who benefited from treatment (p = 0.001). CONCLUSION US and UE can be useful in the diagnosis of CTS and its response to treatment, if used together with clinical and electroneurophysiological tests.

Abstract
Background: Diagnosis of carpal tunnel syndrome is based on clinical symptoms, examination findings, and electrodiagnostic studies. For carpal tunnel syndrome, the most useful of these are nerve conduction studies. However, nerve conduction studie can result in ambiguous or false-negative results, particularly for mild carpal tunnel syndrome. Increasing the number of nerve conduction studie tests improves accuracy but also increases time, cost, and discomfort. To improve accuracy without additional testing, the terminal latency index and residual latency are additional calculations that can be performed using the minimum number of tests. Recently, the median sensory-ulnar motor latency difference was devised as another way to improve diagnostic accuracy for mild carpal tunnel syndrome. Aims: The median sensory-ulnar motor latency difference, terminal latency index, and residual latency were compared for diagnostic accuracy according to severity of carpal tunnel syndrome. Study Design: Diagnostic accuracy study. Methods: A total of 657 subjects were retrospectively enrolled. The carpal tunnel syndrome group consisted of 546 subjects with carpal tunnel syndrome according to nerve conduction studie (all severities). The control group consisted of 121 subjects with no hand symptoms and normal nerve conduction studie. All statistical analyses were performed using SAS v9.4. Means were compared using one-way ANOVA with the Bonferroni adjustment. Sensitivity, specificity, positive predictive value, and negative predictive value were compared, including receiver operating characteristic curve analysis. Results: For mild carpal tunnel syndrome, the median sensory-ulnar motor latency difference showed higher specificity and positive predictive value rates (0.967 and 0.957, respectively) than terminal latency index (0.603 and 0.769, respectively) and residual latency (0.818 and 0.858, respectively). The area under the receiver operating characteristic was highest for the median sensory-ulnar motor latency difference (0.889), followed by the residual latency (0.829), and lastly the terminal latency index (0.762). Differences were statistically significant (median sensory-ulnar motor latency difference being the most accurate). For moderate carpal tunnel syndrome, sensitivity and specificity rates of residual latency (0.989 and 1.000) and terminal latency index (0.983 and 0.975) were higher than those for median sensory-ulnar motor latency difference (0.866 and 0.958). Differences in area under the receiver operating characteristic curve were not significantly significant, but median sensory-ulnar motor latency difference sensitivity was lower. For severe carpal tunnel syndrome, residual latency yielded 1.000 sensitivity, specificity, positive predictive value, negative predictive value and area beneath the receiver operating characteristic curve. Differences in area under the receiver operating characteristic curve were not significantly different. Conclusion: The median sensory-ulnar motor latency difference is the best calculated parameter for diagnosing mild carpal tunnel syndrome. It requires only a simple calculation and no additional testing. Residual latency and the terminal latency index are also useful in diagnosing mild to moderate carpal tunnel syndrome.
