简要总结
The long-term goal for this study is to understand the physiological mechanisms of various forms of spinal manipulation in order to refine and improve this therapy for appropriately selected patients. The objective of this study is to assess the effects of high-velocity low-amplitude spinal manipulation and low-velocity variable amplitude spinal manipulation on three types of sensorimotor abilities in patients with low back pain.
详细描述
In collaboration with the University of Iowa, the Palmer Center for Chiropractic Research will pursue the following specific aim: To determine the effects of 2 weeks (4 applications @ 2 per week) of HVLA-SM and LVVA-SM to the lumbo-pelvic region, compared to a control group receiving light effleurage and a sham mechanically assisted adjustment, on sensorimotor function as measured by: lumbo-pelvic repositioning ability, standing postural sway and response to sudden trunk loading;

入选标准
- •21 to 65 years old
- •Low back pain (LBP) score an 11 point numerical rating scale: (must be > 4 at the Phone Screening OR Baseline 1 Visit) AND (must be > 2 at the Phone Screen, Baseline 1 AND Baseline 2 Visits)
- •Acute (less than 7 days), sub-acute (7 days to 7 weeks), or chronic (more than 7 weeks) LBP matching classifications 1, 2, or 3 of the Quebec Task Force (QTF) Classification system - QTF 1: Pain without radiation, QTF 2: Pain + radiation to proximal extremity, QTF 3: Pain + radiation to distal extremity, QTF 7: Spinal stenosis
- •Written informed consent (ICD1, ICD2 and ICD3)
排除标准
- •Ongoing treatment for low back pain by other health care providers - unwillingness to postpone use of all other types of manual treatment for LBP except those provided in the study (including chiropractic and osteopathic SM, physical therapy and massage) for the duration of the study period.
- •Co-morbidities Bleeding Disorders Bone and Joint Pathology Cauda Equina Syndrome Contra-indication to spinal manipulation, in general Current or Pending Litigation General Poor Health Inflammatory or Destructive tissue changes to the spine Neuromuscular Diseases Obesity Osteoporosis Peripheral Neuropathies Spinal Surgery Suspicion of drug or alcohol abuse Uncontrolled hypertension Vascular claudication
- •Quebec Task Force (QTF) on Spinal Disorders QTF 4: Pain + radiation to upper/lower limb with neurologic signs QTF 5: Presumptive compression of a spinal nerve root on a simple roentgenogram QTF 6: Compression of a spinal nerve root confirmed by specific imaging techniques QTF 8: Postsurgical status, 1-6 months after intervention QTF 9: Postsurgical status, >6 months after intervention 9.1: Asymptomatic 9.2: Symptomatic QTF 10: Chronic pain syndrome QTF 11: Other diagnoses
- •Pregnant or nursing women
- •Pacemaker
- •Inability to read or verbally comprehend English
- •Any Joint Replacement
- •Use of spinal manipulation within the past 4 weeks. If participants are willing to delay study enrollment until four weeks post spinal manipulative therapy, then we will schedule accordingly until this criterion is met
- •Sensitivity to tape used during the biomechanical assessments
- •If the Study Clinician believes that diagnostic procedures other than x-rays or dipstick urinalysis are necessary to diagnose a participant's condition, then the participant will be excluded
- •Beck Depression Inventory-II greater than or equal to 29
- •Retention of legal advice and an open or pending case for a health-related condition

结局指标
主要结局
Postural Sway
时间窗: Baseline and 2 weeks
Changes in sensorimotor function, as measured by postural sway in patients with LBP from baseline to 2 weeks. The adjusted within-group mean changes from baseline to two week follow-up are detailed below for: Postural sway (AP=mean excursion in the anterior-posterior direction, ML= mean excursion in the medial-to-lateral direction.
Response to Sudden Load Response Times
时间窗: Baseline and 2 weeks
Changes in sensorimotor function, as measured by response to sudden load in patients with LBP from baseline to 2 weeks. The adjusted within-group mean changes from baseline to two week follow-up are detailed below for for Response to sudden load \[RTSL\] (ant. COP=anterior movement in center of pressure, L=left side of erector spinae, R=right side of erector spinae)
Response to Sudden Load, Peak Muscle Response Per Side
时间窗: Baseline and 2 weeks
Changes in sensorimotor function, as measured by response to sudden load in patients with LBP from baseline to 2 weeks. The adjusted within-group mean changes from baseline to two week follow-up are detailed below for for Response to sudden load \[RTSL\] (ant. COP=anterior movement in center of pressure, L=left side of erector spinae, R=right side of erector spinae)
Postural Sway Speed
时间窗: Baseline and 2 weeks
Changes in sensorimotor function, as measured by postural sway speed in patients with LBP from baseline to 2 weeks. The adjusted within-group mean changes from baseline to two week follow-up are detailed below for: Sway Speed=overall center of pressure traveling distance divided by time.
Response to Sudden Load, Anterior Movement in Center of Pressure Excursion in SL
时间窗: Baseline and 2 weeks
Changes in sensorimotor function, as measured by response to sudden load in patients with LBP from baseline to 2 weeks. The adjusted within-group mean changes from baseline to two week follow-up are detailed below for Response to sudden load \[RTSL\], ant. COP=anterior movement in center of pressure
