简要总结

This study will compare the use of RESCU [Experimental] Prosthesis with a [Standard] pattern recognition prosthesis in a clinical setting and in unsupervised daily activity. The protocol will follow a single case experimental design (SCED) to compensate for the limited size of the patient population. Each of the participants will use the Standard and Experimental and systems over a 35-day period. The Standard system will include at least two controllable DoFs (hand, wrist, multi-articulated hand, etc) and a commercially-available pattern recognition controller. The RESCU system will use the same components as the Standard system but will differ with respect to incorporating eight IBT Element Electrodes (as required for pattern recognition control) and the RESCU control software. The hypothesis is that pattern recognition will outperform the commercially-available control strategy for most participants on in-clinic, at-home usage, and subjective measures.

详细描述

The AB sequence for the study protocol is described below, where control type A is the Standard prosthesis and control type B is the Experimental prosthesis.

On Day 0, the participant will be evaluated with the Standard prosthesis. A series of Measures (as defined in the next paragraph) will then be recorded. The participant will then take the prosthesis home for one week, and daily use data will be recorded. The participant will return to the clinic for Day 7 Measures and download of the daily use data. During this session, the participant will be fit with the second system, undergo occupational therapy in the clinic, and Measures will be recorded. There will be no washout period as the prosthesis is expected to be in daily use. The participants will go home for a four-week period and return on Day 35 for a third set of Measures. At this time, the participant will be asked which prosthesis he/she prefers.

There are limited functional outcome assessment options for the planned comparison. However, the investigators will test functional measures at the clinic appointments, examine daily use data, and administer several qualitative surveys to assess participant outcomes.

结局指标

主要结局

Mean Daily Prosthesis Use Duration

时间窗: Baseline, 4 weeks

Prosthesis usage time was monitored as a proxy for user satisfaction, under the assumption that when an individual is more satisfied with their prosthetic solution, they will use it more in their daily lives. For the experimental intervention, the mean daily prosthesis use duration is reported as the average number of hours the prosthesis was used daily over the evaluation period (i.e., four weeks). For the control intervention, the mean daily prosthesis use duration is reported as the average number of hours the prosthesis was used daily before the evaluation period (i.e., at baseline).
