Trial Outcomes & Findings for The Effect of FES on Children With Spinal Cord Injury (NCT NCT00291317)

Results Overview

The PedsQL™ 4.0 is a modular instrument for measuring health-related quality of life in children and adolescents. The questionnaire asks how much of a problem each item has been during the past month, using a 5-point response scale. This study used the Emotional Functioning, Social Functioning, and School Functioning modules. Scores on these three modules are combined to yield a Psychosocial Health Summary Score (range = 0-100 with 100 being the maximum positive outcome). Pre- and post-intervention scores were compared to determine improvement.

Participant milestones
Measure	FES Cycle Exercise Participants exercised using functional electrical stimulation cycling (FES) using the RT 300 FES cycle (Restorative Therapies, Baltimore, MD). Stimulation rpm (45-50), pulse duration (250 μs), and frequency (33.3 Hz) were fixed. Amplitude ranged from 70-120mA, and average stim ranged from 16.50-29.7 μC. Participants were monitored for autonomic dysreflexia during training. Blood pressure and heart rate were monitored during the initial evaluation and the first session of cycling. Once it was established that there were no adverse physiological responses, ongoing blood pressure and heart rate monitoring did not continue for subsequent sessions. No participant experienced a dysreflexive episode in response to electrical stimulation during this study. Children were scheduled to attend three cycling sessions per week on non-consecutive days for up to 30 minutes (plus a 2 minute warm up and 30 second cool down) per session over a 9 month period.

PRIMARY outcome

Timeframe: pre- and post-intervention; time frame among participants ranged from 4 to 12 months

Population: Four of the six participants completed the PedsQL on at least 2 occasions. At minimum, each completed the PedsQL at their initial evaluation before beginning the cycling program and at or following their last cycling session.

PRIMARY outcome

Timeframe: At entry until completion (range 4-14 months) (One participant's DEXA scan was obtained late due to illness)

Bone mineral density (BMD) was measured with Dual X-ray Absorptiometry (DEXA) scans using a GE LUNAR system. DEXA has been used in patients with loss of ambulation due to SCI to monitor changes in body composition over time and to evaluate the effectiveness of exercise in preventing or reducing the disease-related complications of SCI. It was used in the present study to determine BMD in the right distal femur at baseline; after 3 months of intervention; after 6 months; and for children who biked for the full duration of the study, at the completion of 9 months of intervention.
