Background: Cerebral palsy (CP) is the most frequent cause of childhood disability in the US. Nevertheless, current standard of care for CP in the U.S. is to a large extent ineffective. The Chinese, on the other hand, claim to have an exceptionally high response rate with the administration of an integrated package of care that includes the combination of intense 'conventional' therapies and acupuncture. Despite numerous anecdotal reports, this claim has not yet been tested in a rigorous scientific way. Objective: To determine the effectiveness of acupuncture when used as an adjunct to intense 'conventional' physical, occupational, and hydro- therapies to improve function and quality of life in children with spastic CP. Hypotheses: (1) Adjunctive acupuncture therapy will improve the gross and fine motor function and the health related quality of life of children with spastic CP more than intense 'conventional' therapies alone. (2) The level of persistence of gross and fine motor function and health related quality of life achieved with adjunctive acupuncture administered in combination with intense 'conventional' therapies will be higher than those achieved with intense 'conventional' therapies alone. Design: A parallel, two-arm, prospective, evaluation-blind, pragmatic, non-inferiority, randomized controlled clinical trial (RCT). Setting: This international collaborative study will be conducted at two different localities: (1) At the Beijing Children's Hospital (BCH), where participants' recruitment, intervention therapies, videotape evaluation, and data collection will be done, and (2) At the University of Arizona, where scoring of the videotape evaluations and data analyses will be done, and from where logistic support will be provided to assure the scientific integrity of the study. Population: Approximately 100 children between the ages 1 and 6 years with spastic CP. Intervention: Concurrent administration of acupuncture with intense 'conventional' therapies at the outset of the study vs. sequential administration of both components. Outcomes: 'Gross Motor Function', 'Fine Motor Function', 'Range of Motion', 'Level of Motor Involvement', and 'Health-Related Quality of Life' measured at times 0,4,8,12,24,and 36 weeks. Evaluation: Independent blinded evaluation with respect to the type of the intervention and the stage of the therapeutic schedule done in the U.S. based on videotapes filmed in China. Data management: Web-based data center and intersite-networking infrastructure. Data analyses: Intention to treat analysis supplemented by linear mixed effects models with nested grouping factors. Significance and future directions: If the hypotheses are confirmed the study would lay the groundwork for future research, and impact clinical practice and health care policy as related to CP therapy.
