Trial Outcomes & Findings for Exercise Study of Function and Pathology for Women With X-linked Adrenoleukodystrophy (NCT NCT01594853)

NCT ID: NCT01594853

Last Updated: 2018-08-29

Results Overview

Here, we will assess whether the degree of a person's white matter integrity (i.e. for tracts of interest as measured from MRI) predicts their ability to benefit from exercise. Our prediction is that those individuals with preserved white matter integrity will show the greatest improvement in hip flexor strength.

Measure
Female Carriers
Female carriers will participate in an exercise paradigm. exercise training: The exercise program uses a local Curves® gym to provide an individualized program of strength and cardiovascular training. The program is expected to be performed for 45 minutes 4-6 days per week.
Healthy Controls
Healthy age and gender matched individuals will participate in an exercise paradigm. exercise training: The exercise program uses a local Curves® gym to provide an individualized program of strength and cardiovascular training. The program is expected to be performed for 45 minutes 4-6 days per week.

PRIMARY outcome

Timeframe: Participants are assessed at baseline (visit 1, enrollment), end of training (visit 2, week 12) and post-training (visit 3, week 18).

Population: For the follow up visit, there are fewer participants in the analysis because 5 female carriers and 1 control were unable to return for the third follow up visit due to burden to travel costs.

Here, we will assess whether the degree of a person's white matter integrity (i.e. for tracts of interest as measured from MRI) predicts their ability to benefit from exercise. Our prediction is that those individuals with preserved white matter integrity will show the greatest improvement in hip flexor strength.
