Last verified: April 2013
It is the purpose of this study to attempt to determine if there is an immediate, measurable change in visual function as a direct result following a session of cranial osteopathic manipulation.

Condition Intervention
Visual Function
Procedure: Cranial osteopathic manipulation
Procedure: Sham/Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind
Primary Purpose: Treatment
Official Title: Effect of Cranial Osteopathy on Visual Function

Further study details as provided by Nova Southeastern University:

Primary Outcome Measures:
  • Accommodative system testing Visual acuity testing Stereoacuity testing Vergence system testing Pupillary testing [ Time Frame: Immediately after intervention. ]

Enrollment: 29
Study Start Date: October 2001
Study Completion Date: February 2002
Arms Assigned Interventions
Experimental: 1
Assessment for cranial strain patterns, followed by indirect osteopathic treatment of dysfunctions found on assessment, followed by reassessment.
Procedure: Cranial osteopathic manipulation
This treatment is performed by exaggerating the motion asymmetry with a minimum of pressure (a few ounces) and holding the position until the motion becomes symmetrical.
Sham Comparator: 2
Assessment for cranial strain patterns, followed by laying on of hands, followed by reassessment.
Procedure: Sham/Placebo
A laying on of hands with no treatment being performed.
