Trial Outcomes & Findings for NMES Efficacy on Patients With NBPP (NCT NCT01999465)

NCT ID: NCT01999465

Last Updated: 2018-12-14

Results Overview

One of the two-blinded occupational therapists will conduct the evaluation at enrollment and 3-month follow-up clinic visit. In this study, we will evaluate the biceps strength using the British Medical Research Council (MRC) grading system. The British Medical Research Council (MRC) grading system for muscle strength is based on a scale from 0 (minimum score, not testable), 1, 2, 3, 4, to 5 (maximum score, normal strength); higher score means better outcome. British Medical Research Council (MRC) grade 2 or higher is functional in terms of muscle power. In current study, we will examine the change of biceps British Medical Research Council (MRC) grade from baseline to 3-month.

PRIMARY outcome

Timeframe: Baseline to 3-month.

Population: One in the Standard NMES cohort was lost of follow-up and two in the sham cohort were lost of follow-up at 3 months.

In this study, we will evaluate the biceps strength using the British Medical Research Council (MRC) grading system. The British Medical Research Council (MRC) grading system for muscle strength is based on a scale from 0 (minimum score, not testable), 1, 2, 3, 4, to 5 (maximum score, normal strength); higher score means better outcome. British Medical Research Council (MRC) grade 2 or higher is functional in terms of muscle power.

PRIMARY outcome

Timeframe: Baseline to 3-month.

Population: One in the Standard NMES cohort was lost of follow-up and two in the sham cohort were lost of follow-up at 3 months.

One of the two-blinded occupational therapists will assess the active range of motion (AROM) of elbow flexion using goniometer at enrollment and 3-month follow-up clinic visit. The minimum degree is 0 and the maximum degree is 150; the higher degree means better outcome. We will then examine the change of elbow flexion active range of motion (AROM) from baseline to 3-month.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to 3-month.

Study coordinators will conduct one-minute video recording with patient in supported sitting position in a chair or seated on parents lap at initial and monthly clinic visits. A toy, pacifier, or bottle will be provided to trigger patient's spontaneous hand-to-mouth movement. The frequency of hand to mouth motion will be recorded and separated out as to the positioning of the elbow. We are evaluating the motion to determine if the motion of the elbow flexion is against gravity, (the arm held at the side of the body or in an adducted position) or in gravity-eliminated position, (the arm held away from the body or in an abducted position). We are looking at the strength of the biceps in its ability to lift the arm against gravity during functional hand to mouth activities. The NMES unit will not be in use during the videotaping process; we are looking at the spontaneous movement of the extremity.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to 3-month.

Parents will complete a survey asking participant's current therapy program, including therapy type, setting, frequency, duration, other treatment activities, splint usage, home range of motion exercise program and its frequency and duration at initial and monthly follow-up visits. The purpose of this survey is to help us understand whether there are potential confounders that could affect the study result.
