Trial summary

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with involving compression of the median nerve in the carpal tunnel. Rather than other progressive disease, CTS is characterized by remission and recurrence. Read more about this study

About this study

Official title: Perineural Injection Therapy With Vitamin B12 for Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with involving compression of the median nerve in the carpal tunnel. Rather than other progressive disease, CTS is characterized by remission and recurrence. The hydrodissection could decrease the entrapment of nerve to restore blood supply. In addition, the Vitamin B12 was considered to be beneficial for peripheral neuropathy and pain relief. The investigators design a randomized, double-blind, controlled trail to assess the effect after ultrasound-guided hydrodissection with Vitamin B12 in patients with CTS.

Read the detailed description

After obtaining written informed consent, patients with mild to moderate CTS will been randomized into intervention and control group. Participants in intervention group received one-dose ultrasound-guided hydrodissection with 3cc Vitamin B12 and control side received one-dose ultrasound-guided injection 3cc normal saline. No additional treatment after injection through the study period. The primary outcome is Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) and secondary outcomes include visual analog scale (VAS), cross-sectional area (CSA) of the median nerve, sensory nerve conduction velocity of the median nerve. The evaluation was performed pretreatment as well as on the 2nd week, 1st, 2nd, 3rd and 6th month after the treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline of severity of symptoms and functional status on 2nd week, 1st, 2nd, 3rd and 6th month after injection

    Boston carpal tunnel syndrome questionnaire (BCTQ) is a frequently used patient-based questionnaire for measurement of CTS which encompasses two components. In total, 11 questions and 8 items were evaluated to rate the symptom severity scale (SSS) and functional status scale (FSS), respectively. Both subscales range from 1 to 5 with a higher score indicating a higher degree of disability. The mean of total SSS and FSS divided with each item score were used for further analysis.

    Measured: Pre-treatment, 2nd week, 1st, 2nd, 3rd and 6th month after injection

Secondary outcomes (3)

  1. Change from baseline of pain on 2nd week, 1st, 2nd, 3rd and 6th month after injection

    Digital pain severity or paresthesia/dysthesia was evaluated using visual analog scale (VAS). Pain score scale ranged from 0 to 10, with 10 indicating the most severe pain.

    Measured: Pre-treatment, 2nd week, 1st, 2nd , 3rd and 6th month after injection

  2. Change from baseline of cross-sectional area of the median nerve on 2nd week, 1st, 2nd, 3rd and 6th month after injection

    Using the musculoskeletal sonogram to measure the cross-sectional area of the median nerve before treatment and multiple time frame after treatment.

    Measured: Pre-treatment, 2nd week, 1st, 2nd , 3rd and 6th month after injection

  3. Change from baseline of electrophysiological measurement on 2nd week, 1st, 2nd, 3rd and 6th month after injection

    Antidromic sensory nerve conduction velocity of the median nerve before treatment and multiple time frame after treatment.

    Measured: Pre-treatment, 2nd week, 1st, 2nd , 3rd and 6th month after injection

The record says: withdrawn, as of the sponsor's last update on 8 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?
