Conservative therapeutic management of carpal tunnel syndrome

Local ozone injection compared to local glucocorticoid injection in carpal tunnel syndrome: A randomized controlled trial

Objectives

This study aimed to compare the effectiveness of local ozone (O3) injection versus corticosteroid injection in the treatment of mild to moderate carpal tunnel syndrome (CTS).

Patients and methods

This double-blind randomized controlled trial was performed on 42 patients (9 males, 33 females; mean age: 46.7±2.1 years; range, 18 to 70 years) with mild to moderate CTS between May 2021 and June 2021. The corticosteroid group (n=21) was injected with 40 mg triamcinolone, and in the O3 group B (n=21), 4 mL of a 10 mcg/mL oxygen (O2)-O3 mixture was injected. Symptom severity and functional impairments were assessed using a Visual Analog Scale and Boston Carpal Tunnel Questionnaire. Electrodiagnostic and ultrasonographic parameters were obtained at baseline and eight weeks after the procedure.

Results

The O2-O3 solution improved pain and Boston Carpal Tunnel Questionnaire score after eight weeks (p<0.001); however, the change was nonsignificant compared to the corticosteroid group (p>0.05). Sensory nerve and compound muscle action potential latencies were not significantly changed eight weeks after O2-O3 injection (p>0.05), while both were significantly decreased in the steroid injection group (p<0.001). Volar bulging and median nerve cross-section surface area were not improved after O2-O3 injection, while the improvement was significant in the corticosteroid arm (p=0.02).

Conclusion

Symptoms in patients with mild to moderate CTS may be alleviated by local O2-O3 injection; however, electrodiagnostic and ultrasonographic indices may be unchanged. Corticosteroid local injection may alleviate patient symptoms along with electrodiagnostic and ultrasonographic parameters.

Effectiveness of Tendon and Nerve Gliding Exercises in the Treatment of Patients With Mild Idiopathic Carpal Tunnel Syndrome: A Randomized Controlled Trial

BACKGROUND

There is limited evidence regarding the efficacy of different treatment options in patients with carpal tunnel syndrome (CTS). This study aimed at assessing the effectiveness of nerve and tendon gliding exercises in the treatment of patients with mild CTS.

METHODS

The current prospective, randomized trial with pretest-posttest design was conducted on 80 patients with mild CTS randomly assigned to 2 groups. The treatment group was instructed to perform gliding exercises in addition to the wrist splint use. The control group only used the wrist splint. All the patients were instructed to use the splint at night and during the day if required. Patients were evaluated in terms of clinical parameters (ie, grip and pinch strength). The severity of symptoms and functional status was also determined using the Boston Carpal Tunnel Syndrome Questionnaire. The subjects were followed up for 6 weeks.

RESULTS

There were no significant differences in all parameters between groups. The pretest-posttest analysis showed a statistically significant improvement in subjective and objective parameters in the treatment group. However, in the control group, only a significant improvement was observed in grip strength. Wrist splint use led to a significant change in the severity of symptoms only over the second week.

CONCLUSIONS

Both gliding exercise and wrist splint groups showed some improvement in the severity of symptoms and functional status scores. However, the gliding exercises did not offer additional benefit compared with wrist splint alone.

How to Differentiate Pronator Syndrome from Carpal Tunnel Syndrome: A Comprehensive Clinical Comparison

The diagnostic process that allows pronator syndrome to be differentiated reliably from carpal tunnel syndrome remains a challenge for clinicians, as evidenced by the most common cause of pronator syndrome misdiagnosis: carpal tunnel syndrome. Pronator syndrome can be caused by compression of the median nerve as it passes through the anatomical structures of the forearm, while carpal tunnel syndrome refers to one particular topographic area within which compression occurs, the carpal tunnel. The present narrative review is a complex clinical comparison of the two syndromes with their anatomical backgrounds involving topographical relationships, morphology, clinical picture, differential diagnosis, and therapeutic options. It discusses the most frequently used diagnostic techniques and their correct interpretations. Its main goal is to provide an up-to-date picture of the current understanding of the disease processes and their etiologies, to establish an appropriate diagnosis, and introduce relevant treatment benefiting the patient.

Physical therapy versus radial extracorporeal shock wave therapy in the treatment of carpal tunnel syndrome: A randomized-controlled study

Objectives: This study aims to compare the efficacy of physical therapy (PT) and radial extracorporeal shock wave therapy (rESWT) in the treatment of carpal tunnel syndrome (CTS).

Patients and methods: Between May 2020 and July 2020, a total of 125 wrists of 95 patients (22 males, 73 females; mean age: 54.3±11.3 years; range, 19 to 69 years) with mild-to-moderate CTS were allocated into three groups and evaluated. The control group (Group 1, n=42) was treated with splinting and an exercise program. Group 2 (n=42) was treated with a total of three sessions of rESWT, splinting and an exercise program. Group 3 (n=41) was treated with a total of 15 sessions of PT modalities, splinting, and an exercise program. Each patient was evaluated before, three weeks and 12 weeks after treatment using a Visual Analog Scale (VAS), the Boston Carpal Tunnel Questionnaire (BCTQ), the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale, and electrodiagnostic testing.

Results: The reduction in VAS, BCTQ, LANSS, and improvement in sensory nerve conduction velocity were significantly greater at three and 12 weeks of follow-up in Groups 2 and 3, compared to Group 1 (p<0.001). A greater improvement was observed in all clinical parameters in Group 2, compared to Group 3 (p<0.001).

Conclusion: This is the first study to compare the treatment outcomes of PT and rESWT in the treatment of CTS. The results of this study show that both PT and rESWT are effective in the treatment of CTS; however, rESWT yields superior treatment effects compared to conventional PT. The practicalities of administering rESWT and its efficacy in the treatment of CTS may make it the treatment of choice.

Short-term effects of dry needling of thenar muscles in manual laborers with carpal tunnel syndrome: a pilot, randomized controlled study

STUDY DESIGN

Pilot, randomized, single-blinded controlled clinical trial.

BACKGROUND AND OBJECTIVE

Trigger point (s) (TrPs) in thenar muscles could be a cause of narrowing of carpal tunnel in manual laborers with carpal tunnel syndrome (CTS). Effects of dry needling (DN) on the treatment of muscle tension have been reported, but no research has been done on the effect of DN on thenar tight muscles on reducing CTS symptoms. The aim of this study was to assess the effect of DN of thenar muscles TrPs in the treatment of mild-to-moderate carpal tunnel syndrome.

METHODS

Thirty manual laborers with mild-to-moderate CTS and the presence of TrP(s) in thenar muscles were randomized to DN group (n = 15) and control group (waiting list) (n = 15). The DN group received 2 sessions of DN of thenar muscles TrP(s), with a 48-h interval. The control group received no treatment. Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were the primary outcome, while secondary outcomes included electrophysiological domains, pinch and grip strength. Outcome measures were obtained at baseline, 48 hours, and 2 weeks after treatment (follow-up). Two-way analysis of variance (2 groups × 3 times) was used to compare within- and between-group differences. Bonferroni post hoc test was used to find any significant differences in the main effect for group, time, or interaction (group time).

RESULTS

A baseline assessment revealed no intergroup differences in all evaluated parameters (P > .05). Compared to the control group, the DN group had a statistically significant improvement in pinch and grip strength, median SDL, and BCTQ score after 2 weeks (P < .05). There were no between-group differences in the assessment of motor electrophysiologic and SNCV findings (P > .05).

CONCLUSION

Dry needling of thenar TrP(s) is effective in short-term improvement of function in manual laborers with mild-to-moderate CTS.

Quality of Carpal Tunnel Syndrome Patient Education Handouts Available on the Internet: A Systematic Analysis of Content and Design

OBJECTIVE

To evaluate the quality of carpal tunnel syndrome (CTS) patient education handouts and identify the best resources for patients and clinicians.

DESIGN

A document content analysis of handouts identified through a systematic internet search using 8 search terms on Google and Bing and a hand search of professional association websites.

SETTING

Not applicable.

PARTICIPANTS

Documents (N=56) were identified from the top 50 search results across 16 individual searches. Included documents provided general patient education for CTS; descriptive websites, videos, and research studies were excluded.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Content analysis was conducted using the Information Score (IS) tool to evaluate completeness of information (0%-100%) and misleading treatment recommendations were identified. Design analysis was conducted using the Patient Material Assessment Tool for Printable Materials (PEMAT-P) (0%-100%) and 2 widely used readability formulas, Flesch Reading Ease and Flesch Kincaid Grade Level. Using these results, all handouts were rated with a summative 12-point scale.

RESULTS

Of 805 unique search results, we included 56 CTS handouts. The average IS was 74.6%±17.9%, and 78.6% of the handouts mentioned non-evidence-based treatment recommendations. The average PEMAT-P score was 70.2%±10.9%, and the average readability grade level was 7.7±1.7. Only 3 handouts were identified as high quality based on the 12-point summative scores, 22 handouts had mixed quality, and 17 handouts had low quality on both content and design.

CONCLUSIONS

Findings of this study suggest a lack of high-quality and easily understandable CTS patient education handouts. Most handouts contained unreliable treatment information. Improvements are needed to ensure patients' ability to understand and manage this condition.

Does diabetes mellitus change the carpal tunnel release outcomes? Evidence from a systematic review and meta-analysis

STUDY DESIGN

A systematic review and meta-analysis.

INTRODUCTION

Carpal tunnel syndrome (CTS) is one of the most common upper extremity conditions which mostly affect women. Management of patients suffering from both CTS and diabetes mellitus (DM) is challenging, and it was suggested that DM might affect the diagnosis as well as the outcome of surgical treatment.

PURPOSE OF THE STUDY

This meta-analysis was aimed to compare the response with CTS surgical treatment in diabetic and nondiabetic patients.

METHODS

Electronic databases were searched to identify eligible studies comparing the symptomatic, functional, and neurophysiological outcomes between diabetic and nondiabetic patients with CTS. Pooled MDs with 95% CIs were applied to assess the level of outcome improvements.

RESULTS

Ten articles with 2869 subjects were included. The sensory conduction velocities in the wrist-palm and wrist-middle finger segments showed a significantly better improvement in nondiabetic compared with diabetic patients (MD = -4.31, 95% CI = -5.89 to -2.74, P < .001 and MD = -2.74, 95% CI = -5.32 to -0.16, P = .037, respectively). However, no significant differences were found for the improvement of symptoms severity and functional status based on the Boston Carpal Tunnel Questionnaire and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire as well as motor conduction velocities and distal motor latencies.

CONCLUSION

Metaresults revealed no significant difference in improvements of all various outcomes except sensory conduction velocities after CTS surgery between diabetic and nondiabetic patients. A better diabetic neuropathy care is recommended to achieve better sensory recovery after CTS surgery in diabetic patients.

Physical Therapy and Rehabilitation Approaches in Patients with Carpal Tunnel Syndrome

Physical therapy involves a set of factors and methods that affect the biological processes in the body. It is widely used, relatively inexpensive, non-invasive, and easy to apply. Physiotherapy is also used in the treatment of patients with carpal tunnel syndrome (CTS). This syndrome represents the most common compressive mononeuropathy of the upper limb and leads to significant disability. Hence, its successful treatment leads to significant benefits for both the patient and society. There is no established algorithm for the use of physical therapy in these patients. In this publication, we present the physiotherapeutic methods used for the treatment of CTS both before and after surgical treatment.

Electrophysiological responsiveness and clinical outcomes of local corticosteroid injection in the treatment of carpal tunnel syndrome

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.

Clinical evidence and mechanisms of growth factors in idiopathic and diabetes-induced carpal tunnel syndrome

Carpal tunnel syndrome (CTS) is an entrapment neuropathy caused by compression and irritation of the median nerve, which travels through the carpal tunnel in the wrist. Increased fibrosis is a hallmark of the development and pathology of CTS. Different growth factors have been demonstrated to play a potential role in the development of CTS. Studies have described an increase in the expression of growth factors, including Transforming Growth Factor (TGF-β), Vascular Endothelial Growth Factor (VEGF) and interleukins (growth factors for immune and inflammatory cells) in SSCT (sub-synovial connective tissue) in CTS patients. Additionally, SSCT fibrosis is also marked by increased activation of canonical TGF-β second messenger Smads, increased expression of downstream fibrotic mediators such as connective tissue growth factor (CTGF), increased production of collagen type I, II, III and IV, and decreased expression of matrix metalloproteinases. Anti-fibrotic such as anti-TGF treatment may prove beneficial in idiopathic patients, however, anti VEGF therapy can be successful in the diabetic CTS patients. The present review describes the clinical evidence stating the role of different growth factors in the development of fibrosis in idiopathic and diabetes induced CTS.
