Pilot Study on The Effectiveness of Relative Motion Orthosis in Finger Motion
What this study is about
The purpose of this feasibility pilot study is to determine the effectiveness of Relative Motion Orthosis (RMO) in regaining finger range of motion compared to standard care in patients diagnosed with Proximal Interphalangeal (PIP) stiffness with an extension lag secondary to finger injury.
View original scientific description
The purpose of this feasibility pilot study is to determine the effectiveness of Relative Motion Orthosis (RMO) in regaining finger range of motion compared to standard care in patients diagnosed with Proximal Interphalangeal (PIP) stiffness with an extension lag secondary to finger injury. Participants will be enrolled and randomized into groups receiving either standard conservative interventions or standard interventions in addition to the RMO. The primary endpoint is to evaluate the efficacy of relative motion orthosis in PIP ROM using clinical scoring and physical exam findings.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age range 18-80
- Any Proximal Interphalangeal (PIP) injury that causes reduced PIP Active Range of Motion (AROM) in extension
- Right or left hand injury
- Level of Chronicity (4 weeks - 6 months)
- Able to follow instructions
Exclusion criteria
- PIP with hard end feel (feels they need serial casting) - level of chronicity
- Any digital nerve injury / skin laceration that can prevent the patient from using the orthosis
- Severe arthropathy
- Literacy deficits: patients need to be able to follow verbal and written instructions independently to minimize risks and improve outcomes from care.
Where
- New York, New York
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
