We examined cord motion and cord-spine coupling associated with the axial tension and dorsal impact models of spinal cord injury. In 20 cats, distraction forces up to 15 kg were applied. Five microliters of radiopaque agent was injected into the central cord at C4-C7 (14 cats) and T6-L1 (6 cats) at 2-mm intervals. In 20 cats, 300 g/cm impacts were delivered(More)
Fifty cats underwent spine distraction with forces applied until the evoked potential (EP) amplitude was reduced 50 or 95%. Neurologic status and EPs were monitored for up to 6 weeks. Fifty percent reduction occurred at (x) = 4.2-kg distraction/kg body weight (BW); 95% at 7.4 kg distraction/kg BW: differences were significant (p less than .05). The 50%(More)
OBJECTIVE The purpose of this study was to determine if elastic therapeutic tape placed on anterior lower limbs would affect stride and step length in fatigued runners' gait. METHODS Forty-two healthy participants were equally divided into a kinesiology tape group (Rocktape) and a no-tape control group. Participants in both groups underwent a baseline(More)
OBJECTIVE The aims of this study were (1) to determine if there were statistically significant immediate effects of anterior upper thoracic chiropractic manipulative therapy on cardiovascular response in normotensive individuals and (2) to quantify responses if any were found. METHODS Thirty-six chiropractic college students (age, 26.8 ± 4.6 years;(More)
PURPOSE The purpose of this study was to pilot test our study procedures and estimate parameters for sample size calculations for a randomized controlled trial to determine if bilateral sacroiliac (SI) joint manipulation affects specific gait parameters in asymptomatic individuals with a leg length inequality (LLI). METHODS Twenty-one asymptomatic(More)
OBJECTIVE The purpose of this study was to evaluate the feasibility of engaging in a series of larger studies measuring the effect of sacroiliac joint manipulation on walking kinematics using motion analysis technology. METHODS Twelve college students engaged in a baseline 90-second gait analysis at 1.5 mph using infrared VICON cameras. Following this,(More)
The Spine Buddy® supportive pad was developed to be inserted underneath military backpacks to help disperse the heavy load of the backpack. The purpose of this study was to determine the impact the additional supportive pad had on static balance and a running gait while wearing a military backpack. Forty healthy subjects (age= 27.5 + 5.6 yrs, body height=(More)
OBJECTIVE The purpose of this pilot study was to collect preliminary information for a study to determine the immediate effects of a single unilateral chiropractic manipulation to the lower cervical spine on handgrip strength and free-throw accuracy in asymptomatic male recreational basketball players. METHODS For this study, 24 asymptomatic male(More)
OBJECTIVE The purpose of this study was to measure the impact of midlumbar spinal manipulation on asymptomatic cyclist sprint performance and hip flexibility. METHODS Twelve cyclists were equally randomized into an AB:BA crossover study design after baseline testing. Six participants were in the AB group, and 6 were in the BA group. The study involved 1(More)
OBJECTIVE The purpose of this study was to describe non-Hispanic blacks that use chiropractic health care to better understand this underserved demographic. METHODS E-mail and telephone calls were used to recruit doctors of chiropractic (DCs) in Texas and Louisiana to distribute anonymous surveys to their non-Hispanic black patients. Twenty doctors(More)
