Effectiveness of Amniotic Membrane Combined With Secretome as an Adjunct to Carpal Tunnel Release Surgery: Evaluation Using the Boston Carpal Tunnel Questionnaire and Electromyography (Secretome CTS)

July 20, 2026 updated by: PT. Prodia Stem Cell Indonesia
Carpal Tunnel Syndrome (CTS) is a compressive neuropathy caused by chronic compression of the median nerve within the carpal tunnel, resulting in pain, numbness, tingling, and impaired hand function. This study is a randomized controlled trial with a pre- and post-intervention experimental design to evaluate the effectiveness of adjunctive amniotic membrane combined with secretome in patients with moderate-to-severe CTS undergoing carpal tunnel release surgery. Participants will be randomly assigned to receive either standard surgical treatment alone or surgery with the addition of amniotic membrane and secretome. Clinical and electrophysiological outcomes will be evaluated before surgery and at 3 weeks after the intervention using the Boston Carpal Tunnel Questionnaire (BCTQ) and electromyography (EMG) to assess symptom improvement, functional recovery, and median nerve regeneration.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Adults aged 18 years or older.
  • Diagnosed with moderate-to-severe Carpal Tunnel Syndrome (CTS) based on electromyography (EMG) according to the Bland classification.
  • Persistent CTS symptoms that have not improved with conservative treatment.
  • Willing and able to provide written informed consent and comply with study procedures.

Exclusion Criteria:

  • Previous carpal tunnel release surgery on the affected wrist.
  • History of wrist trauma or previous wrist surgery.
  • Presence of comorbidities that may affect nerve healing or study outcomes, including diabetes mellitus, hypertension, or metabolic disorders.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Amnion Membrane + Secretome
Biological: Secretome
Participants undergoing carpal tunnel release surgery will receive a 10 mm × 10 mm amniotic membrane soaked in 1.5 mL of secretome solution for 1 minute before application to the median nerve at the surgical site.
Other Names:
  • UC-MSCs-derived Secretome
  • Mesenchymal Stem Cells-derived Secretome
Active Comparator: Amniotic Membrane
Other: amniotic membrane
Participants undergoing carpal tunnel release surgery will receive a 10 mm × 10 mm amniotic membrane applied to the median nerve at the surgical site without secretome.
Placebo Comparator: Standard Surgery
Procedure: Standard surgery
Participants will undergo standard carpal tunnel release surgery without the addition of amniotic membrane or secretome.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Boston Carpal Tunnel Questionnaire (BCTQ) score
Time Frame: Baseline and 3 weeks postoperatively
The Boston Carpal Tunnel Questionnaire (BCTQ), consisting of the Symptom Severity Scale (SSS) and Functional Status Scale (FSS), will be used to evaluate changes in symptom severity and hand function from baseline to 3 weeks after surgery.
Baseline and 3 weeks postoperatively
Electromyography (EMG)
Time Frame: Baseline and 3 weeks postoperatively
Electromyography (EMG) will be performed to assess changes in median nerve electrophysiological function, including nerve conduction parameters, from baseline to 3 weeks after surgery.
