Homeopathic treatment of mild traumatic brain injury: A randomized, double-blind, placebo-controlled clinical trial.
BACKGROUND Mild traumatic brain injury ( MTBI ) affects 750,000 persons in the United States annually . Five to fifteen percent have persistent dysfunction and disability . No effective , st and ard pharmacological treatment exists specifically for this problem . We design ed a pilot research project to study the clinical effectiveness of homeopathic medicine in the treatment of persistent MTBI . METHOD A r and omized , double-blind , placebo-controlled trial of 60 patients , with a four-month follow-up ( N = 50 ) , was conducted at Spaulding Rehabilitation Hospital ( SRH ) . Patients with persistent MTBI ( mean 2.93 years since injury , SD 3.1 ) were r and omly assigned to receive a homeopathic medicine or placebo . The primary outcome measure was the subject-rated SRH-MBTI Functional Assessment , composed of three subtests : a Difficulty with Situations Scale ( DSS ) , a Symptom Rating Scale ( SRS ) , and a Participation in Daily Activities Scale ( PDAS ) . The SRH Cognitive-Linguistic Test Battery was used as the secondary measure . RESULTS Analysis of covariance demonstrated that the homeopathic treatment was the only significant or near-significant predictor of improvement on DSS subtests ( P = .009 ; 95 % CI -.895 to -.15 ) , SRS ( P = .058 ; 95 % CI -.548 to.01 ) and the Ten Most Common Symptoms of MTBI ( P = .027 ; 95 % CI -.766 to -.048 ) . These results indicate a significant improvement from the homeopathic treatment versus the control and translate into clinical ly significant outcomes . CONCLUSIONS This study suggests that homeopathy may have a role in treating persistent MTBI . Our findings require large-scale , independent replication
