---|---|
Experimental: Cranial manipulation
Assessment for cranial strain patterns, followed by indirect cranial manipulation to treat dysfunctions found on assessment, followed by reassessment. Repeated for a total of eight visits no less than one week apart. |
Procedure: Cranial Manipulation
Performed by exaggerating the motion asymmetry with a minimum of pressure (a few ounces) and holding the position until the motion becomes symmetrical.
Other Names:

Sham Comparator: Sham/placebo
Assessment for cranial strain patterns, followed a laying on of hands, followed by reassessment. Repeated for a total of eight visits no less than one week apart.
|
Procedure: Sham/Placebo
A laying on of hands with no actual treatment being performed. |
- Distance Visual Acuity [ Time Frame: Weekly for 16 weeks ]Measurement of visual acuity in each eye by number of letters read correctly on ETDRS chart.
- Accommodative System Testing [ Time Frame: Weekly for 16 weeks ]Accommodative amplitude testing using a Donder push-up card.
- Local Stereoacuity Testing [ Time Frame: Weekly for 16 weeks ]Measured by Random Dot E test.
- Pupillary Size Testing [ Time Frame: Weekly for 16 weeks ]Measurement of pupil size (each eye) in bright and dim light.
- Vergence System Testing [ Time Frame: Weekly for 16 weeks ]Assessed by Cover Test with Prism Neutralization and Near Point of Convergence
