Study Description

Brief Summary:

Sham-controlled, multi-center and remote patient-centered randomized controlled clinical trial to investigate the efficacy of a novel non-invasive, unobtrusive study device in reducing symptoms of carpal tunnel syndrome (CTS). Daily wear of the study device is expected to significantly reduce symptom severity (evaluated by the Boston Carpal Tunnel Questionnaire) in mild to severe CTS-diagnosed patients. Subjects are randomized into the active device group or sham group for 8 weeks, then followed for 12 weeks post-treatment.

Condition or disease	Intervention/treatment	Phase
Carpal Tunnel Syndrome	Device: Study Device; Device: Sham Device	Not Applicable

Detailed Description:

It is hypothesized that daily wear of the study device will result in significant improvements in patient-reported symptom severity. It is also hypothesized that the effects from active study device treatment will be significantly greater than effects from sham treatment. In both cases, it is hypothesized that improvements will be sustained post-treatment.

This study is designed as a randomized, double-blind, sham-controlled, two-arm trial consisting of an eight-week treatment period (active study device or sham), followed by one required follow-up four weeks later (at week 12).

There are two study groups: the active device group receiving the active study device and the sham group receiving a non-active sham device. Subjects will be informed that they have a 50:50 chance of receiving treatment or a sham. They will also be informed that if they receive sham device, they will be offered the active device 4 weeks into the post-treatment period. However, all subjects will not know what treatment they are on until the conclusion of the trial.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Study Device; Small, non-invasive, stiff patch for the wrist	Device: Study Device; Real study device applied to affected wrist (or higher CTS severity wrist if patient has bilateral CTS) for 8-10 hours daily for 56 days (8 weeks).
Sham Comparator: Sham Device; Device that looks like the Study Device but modified to prevent or remove the main mechanism of action.	Device: Sham Device; Sham device applied to affected wrist (or higher CTS severity wrist if patient has bilateral CTS) for 8-10 hours daily for 56 days (8 weeks). *Note: participants in the sham group are given the real study device at the end of the Post-Treatment/Follow-up Phase.

Outcome Measures

Primary Outcome Measures :

1. BCTQ SSS at 8 Weeks vs Baseline [ Time Frame: baseline and 8 weeks post-Baseline ]
   The Symptom Severity Scale (SSS) of the Boston Carpal Tunnel Questionnaire (BCTQ) is an 11-question patient-administered survey that rates the severity of the patient's carpal tunnel syndrome-specific symptoms on a scale of 1 (no symptoms) to 5 (worst symptoms).

Secondary Outcome Measures :

1. BCTQ SSS [ Time Frame: 8-weeks post-Baseline and 12 weeks post-Baseline ]
   The Symptom Severity Scale (SSS) of the Boston Carpal Tunnel Questionnaire (BCTQ) is an 11-question patient-administered survey that rates the severity of the patient's carpal tunnel syndrome-specific symptoms on a scale of 1 (no symptoms) to 5 (worst symptoms).
