Study of Compensatory Motion While Using an Upper Limb Prosthesis
NCT00417352 · View on ClinicalTrials.gov ↗
Study Summary
Current improvements of the design of the upper limb prosthesis include advanced technology in control systems and electronic circuitry that mimic human motion and improve function of the prosthesis. Often times these improvements require large amounts of power, circuitry and excess mass distally along the prosthesis that may require greater effort from the user. Poor function of an upper limb prosthesis may cause awkward compensatory motion. Aberrant movements, such as these compensatory movements are known to cause greater stress to remaining joints. Amputees are forced to decide if the extra function provided by the advanced electronics is worth carrying the extra mass which may cause fatigue, socket issues and greater stress on the remaining joints. An example is the wrist rotator component of an upper limb prosthesis which may allow greater function and reduce compensatory motion, but adds mass distally, potentially causing greater torques on remaining joints. GOALS OF THE STUDY: There are two main goals of this study: 1. to determine the impact of an upper limb prosthesis without a wrist rotator on the compensatory motion and torques in the remaining joints during common tasks 2. to determine the impact of the location (distally or proximally) of a wrist rotator on a upper limb prosthesis on the compensatory motion during common tasks HYPOTHESES: 1. There will be a statistically significant difference in range of motion of the upper limb joints between healthy subjects, braced subjects and upper limb amputees during four common tasks. 2. There will be a statistically significant difference in joint upper limb joint torques between healthy subjects, braced subjects and upper limb amputees during three common tasks. 3. There will be a statistically significant difference in upper limb angles and joint torques between mass added distally and mass added proximally during common tasks.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00417352
The ClinicalTrials.gov registry entry for NCT00417352 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 17 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of South Florida, which has 144 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Prosthesis appearing as the primary indexed condition, and to 2 interventions — of which Brace is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00417352 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
