Influence of SMT on ganglion inflammation. Song et al (p. 5) investigate if activator-assisted spinal manipulative therapy reduces lumbar IVF inflammation-induced pain and hyperalgesia, hyperexcitability of the dorsal root ganglion sensory neurons, and ganglion inflammation. They suggest that manipulation of a specific spinal segment may play an important role in optimizing recovery.
Revisiting radiation exposure and pregnancy. Ursprung et al (p. 83) discuss radiation protection and radiation control measures to assist in counseling pregnant patients exposed to radiation and the rights and responsibilities of both the employer and employee concerning occupational exposure to low-dose ionizing radiation.
The science of HVLA. Pickar and Kang (p. 22) demonstrate that muscle spindle discharge increased substantially as the duration of a spinal manipulation approached that used clinically. One biomechanical characteristic of a high-velocity, low-amplitude thrust is its capacity to load paraspinal muscle spindles at a rate in which the velocity sensitivity predominates over length sensitivity.
Should we rely on the audible “pop”? Flynn et al (p. 40) investigate the relationship between the audible pop during spinal manipulation and improvement in pain, lumbar ROM, and disability in individuals with nonradicular LBP. They suggest that practitioners using manipulation techniques should be cautious in attributing therapeutic benefit to the audible “pop” for patients with nonradicular LBP.
Maximizing the efficiency of manipulation. Evans and Breen (p. 72) present a biomechanical model for producing mechanically efficient cavitation during spinal manipulation through utilization of the prethrust position and the neutral zone.
Are CFS patients hypermobile? Nijs et al (p. 32) compare the prevalence of generalized hypermobility in chronic fatigue syndrome patients and healthy volunteers. They examine the clinical importance of generalized hypermobility and whether proprioception is associated with hypermobility in these patients.
Impact of SMT on pain and inflammation. Injeyan et al (p. 14) investigate the effects of spinal manipulative therapy on the production of inflammatory substances, in relationship to systemic levels of the pain neurotransmitter substance P.
Blood pressure influenced by manipulation? Dimmick et al (p. 46) examine whether chiropractic manipulation is associated with measurable changes in the difference between the arterial blood pressures on the left and right for pretreatment and posttreatment in normal subjects.
Spinal cord and nerve root impingement. Excoffon and Wallace (p. 66) describe the chiropractic treatment and rehabilitation of a patient with progressive lumbar disk injury, spondylolisthesis, and spondyloptosis.
Patient response to impulse therapy. Evans et al (p. 51) perform a retrospective analysis of patient files to determine patient-reported symptomatic improvement to multiple impulse therapy for a variety of musculoskeletal symptoms encountered in clinical practice.
Improving gait with orthotics. Michad and Nawoczenski (p. 60) present the findings of one patient. By lessening first MTP joint dorsiflexion and increasing first metatarsal plantar flexion during the propulsive period, a semirigid orthotic with a varus post allows the patient to avoid the final range of dorsiflexion where the compressive forces acting on the dorsal aspect of the joint are thought to peak.
Shoulder pain of neurogenic origin. Rix et al (p. 52) describe a patient diagnosed with neuralgic amyotrophy and discuss differential diagnosis, the use of clinical neurophysiologic procedures to aid in establishing the diagnosis, and issues of patient management.
