Trial Outcomes & Findings for An Evaluation of Hyperbaric Treatments for Children With Cerebral Palsy (NCT NCT00290186)

NCT ID: NCT00290186

Last Updated: 2014-08-28

Results Overview

GMFM-88: total percent score on 88 items (I) of motor function grouped into 5 dimensions: A) lying and rolling (17 I), B) sitting (20 I), C) crawling and kneeling (14 I), D) standing (13 I), E) walking, running, jumping (24 I). Each item scored on 0-3 scale: 0 = does not initiate, 1 = initiates, 2 = partially completes, 3 = completes. Scores in each dimension determined by dividing score obtained by maximum possible score for that dimension, and multiplying by 100. Range is 0-100% for each: the higher the percent score, the greater the functional ability. Dimension scores and total GMFM-88 score calculated as: A) lying and rolling: (score achieved/51)x100 B) sitting: (score achieved/60)x100 C) crawling and kneeling: (score achieved/42)x100 D) standing: (score achieved/39)x100 E) walking, running, and jumping: (score achieved/72)x 100 GMFM-88 = (%A+%B+%C+%D+%E)/number of dimensions GMFM-66: \[(total score on subset of 66 items/198)x100\]

PRIMARY outcome

Timeframe: Baseline (within 1 week of starting 8-week treatment period) and post-treatment (within 1 week of ending 8-week treatment period)

Population: Analysis included all participants who completed baseline assessments (within 1-week of start of treatment), 40 hyperbaric treatments, and post-treatment assessments (within 1 week of ending treatment).

GMFM-88: total percent score on 88 items (I) of motor function grouped into 5 dimensions: A) lying and rolling (17 I), B) sitting (20 I), C) crawling and kneeling (14 I), D) standing (13 I), E) walking, running, jumping (24 I). Each item scored on 0-3 scale: 0 = does not initiate, 1 = initiates, 2 = partially completes, 3 = completes. Scores in each dimension determined by dividing score obtained by maximum possible score for that dimension, and multiplying by 100. Range is 0-100% for each: the higher the percent score, the greater the functional ability. Dimension scores and total GMFM-88 score calculated as: A) lying and rolling: (score achieved/51)x100 B) sitting: (score achieved/60)x100 C) crawling and kneeling: (score achieved/42)x100 D) standing: (score achieved/39)x100 E) walking, running, and jumping: (score achieved/72)x 100 GMFM-88 = (%A+%B+%C+%D+%E)/number of dimensions GMFM-66: \[(total score on subset of 66 items/198)x100\]

Population: The TOVA was only administered to patients who were 4-8 years old, not visually impaired, and able to complete a practice test. Analysis included all eligible participants who completed baseline assessments (within 1-week of start of treatment), 40 hyperbaric treatments, and post-treatment assessments (within 1 week of ending treatment).

One of 4 parts of the TOVA, a computerized continuous performance test that measures attention and impulsivity in visual mode. Measures the number of times a target is correctly selected when it appears on a screen. Score ranges from 0-160; higher scores represent greater number of correct responses.

Hyperbaric Air Treatment: 14% oxygen at 1.5 ATA for 60 mins, Mon-Fri, 40 treatments total
The Difference Between Groups in Change in Scores (Post-treatment Minus Pre-treatment) on the Test of Variables of Attention (TOVA): Number of Correct Nonresponses.
3 Number of correct nonresponses
Interval -6.0 to 12.0
4 Number of correct nonresponses
Interval -6.0 to 14.0

SECONDARY outcome

Timeframe: Baseline (within 1 week of starting 8-week treatment period) and post-treatment (within 1 week of ending 8-week treatment period)

Population: The TOVA was only administered to patients who were 4-8 years old, not visually impaired, and able to complete a practice test. Analysis included all eligible participants who completed baseline assessments (within 1-week of start of treatment), 40 hyperbaric treatments, and post-treatment assessments (within 1 week of ending treatment).

One of 4 parts of the TOVA, a computerized continuous performance test that measures attention and impulsivity in visual mode. Measures the processing time in milliseconds that it takes to correctly respond to a target. Lower times represent better response times. Range = 0 - 2000 milliseconds

One of 4 parts of the TOVA, a computerized continuous performance test that measures attention and impulsivity in visual mode. Measures the variability in processing time in milliseconds that it takes to correctly respond to a target. Response time variability = the standard deviation of response times for correct responses. Lower values represent less variability and better responses. Range of response times = 0-2000 milliseconds.
