ABSTRACT
Objective To compare the impacts of sustained and intermittent gradient pressure on perfusion disorders and myofiber injuries and to explore the mechanism by which intermittent gradient pressure helps treat deep tissue injury (DTI). MethodsTwenty Sprague-Dawley rats 10-12 weeks old were randomly divided into an experimental group and a control group.The tibialis anterior muscles of the experimental group received intermittent fluctuating pressure at 8.0-21.3 kPa while the control group received sustained pressure at 13.3 kPa.The contralateral notpressed muscles served as healthy controls.The experiment was terminated after 3 cycles of compression where each cycle involved 2 h of compression and 30 min of conpression release.The general condition of the rats'skin and muscles in the compressed region were observed and laser doppler perfusion imaging was used to detect blood perfusion of the skin of the compressed leg after 3 cycles of compression.Any pathomorphological changes in the tibialis anterior muscles of the compressed region were observed by phosphotungstic acid hematoxylin (PTAH) staining. Results Blood perfusion of the skin and muscle in the control group was significantly less than in the experimental group after compression,and blood flow velocity increased with time in both groups.However,perfusion was significantly more extensive in the experimental group.PTAH staining showed that muscle injury in the experimental group was significantly less severe than in the control group. ConclusionCompared to the sustained pressure,intermittent pressure cause significantly less severe DTI by reducing compression-induced ischemia and hypoxia.
ABSTRACT
@# ObjectiveTo evaluate the efficacy and safety of electrical acupuncture therapy through adhesive surface electrodes and concomitant auricular acupuncture therapy on acute spinal cord injury.MethodsA total of 56 acute spinal cord injury patients with American Spinal Injury Association(ASIA) impairment grading of A and B were recruited into this study.They were randomly divided into the acupuncture and control groups.In the acupuncture group,electrical acupuncture therapy via the adhesive surface electrodes and auricular acupuncture were applied.Rehabilitation therapy was also provided to the patients during acupuncture therapy.In the control group,only rehabilitation therapy was provided to the patients.The ASIA neurologic and functional scores and the Functional Independence Measure(FIM) scores were assessed during the time of admission,hospital discharge,and 1-year postinjury follow-up.There were no adverse events.ResultsThere were significant improvements in neurologic(sensory and motor),functional,and FIM scores in the acupuncture group compared with the control either when hospital discharged or 1-year postinjury follow-up.There was no adverse events.ConclusionThe early use of concomitant auricular and electrical acupuncture therapies are effective and safe in treating acute spinal cord injury.
ABSTRACT
@#ObjectiveTo describe 64 cases of cerebrovascular accidents temporally associated with cervical vertebra manipulation therapy in terms of patients' characteristics, potential risk factors, nature of complication, and neurologic sequelae.MethodsThree researchers using a uniform data abstraction instrument performed an independent review of 64 previously medicine records describing cerebrovascular ischemia after cervical vertebra manipulation. Descriptive statistics were calculated for characteristics of the patients and the complications. Means and standard deviations were computed for continuous variables. Frequencies were computed for continuous variables. Frequencies and proportions were calculated for categorical variables.ResultsProposed risk factors include age, gender, migraine headaches, hypertension, diabetes, birth control pills, cervical spondylosis, and smoking. It was unable to identify factors from the clinical history and physical examination of the patient that would assist a physician attempting to isolate the patient at risk of cerebral ischemia after cervical manipulation.ConclusionsCerebrovascular accident after manipulation appear to be unpredictable and should be considered an inherent, idiosyncratic, and rare complication of this treatment approach.
ABSTRACT
Objective To study the etiology and the anatomical factors of the diseases correlated to spinal vertebra. Method On 16corpses, we observed the displacement of the spinal vertebra and its harmfulness after the intervertebral disc or the ligaments damaged. Result It may give rise to displacement of the spinal vertebra moving the cervical spine after the intervertebral structure damaged. The nerve roots may be stimulated when the intervertebral foramen gets narrow to 1/3. When the intervertebral foramen gets narrow to 1/2 the nerve roots may be constricted. When the cervical spinebends on its side 30°the Luschka joint may get displacement. It may stimulate the vertebralis artery and the sympathetic nerve. Conclusion It is the spinal vertebra diaplacement that give rise to spondylopathy and the diseases correlated to spine. This provides an basis for clinical treatment of diseases correlated to spine.
