To describe the relationship between vagally mediated bradycardia and heart rate variability indices in young and older healthy individuals. ⋯ The relationship between HRV and vagal tone is likely complex and has a large interindividual variation.

This article will discuss many of the key concepts regarding chemodenervation and neurolysis in the management of spasticity. Topics that will be discussed include techniques for localization, strengths and limitations of various agents (botulinum toxin, phenol, and alcohol), the value of combination therapies, and the role of nerve blocks (diagnostic and therapeutic). ⋯ During the last 2 decades, the addition of botulinum toxin chemodenervation as an adjunct to traditional neurolysis, medication, and therapy modalities has expanded the field of treatment of intramuscular hyperactivity in upper motor neuron syndrome. The technique of diagnostic blocks as predictors of response and the therapeutic value of nerve blocks will be discussed.

To determine whether posterior pelvic pain is associated with intra-articular hip abnormalities (labral tears and early degenerative changes) in patients with minimal-to-no radiographic abnormalities. ⋯ Twenty percent of patients at the authors' institution who required surgical intervention to treat their pain after not responding to conservative management had posterior pelvic pain in addition to groin or lateral and anterior hip pain. Of those respondents, 33% had complete resolution of symptoms at 4.75 years after surgery, and all had reduction in pain as compared with completion of conservative care. Patients with early intra-articular hip pathology, such as acetabular labral tears with no or mild hip deformity, and patients with arthrosis and mild hip deformity may experience groin and posterior pelvic pain as part of their clinical presentation.

Randomized Controlled Trial
The comparative effectiveness of a multimodal program versus exercise alone for the secondary prevention of chronic low back pain and disability.
The objective of this study was to examine whether a multimodal, secondary prevention program (MP) is superior to a general physical exercise program (EP) in influencing the process leading to chronic low back pain (LBP) in nurses with a history of back pain. ⋯ A multimodal program is not superior to a general exercise program in influencing the process leading to chronic LBP in a population of nurses with a history of pain. The most likely explanation is a common psychological mechanism leading to improved pain interference that is irrespective of the program used. Considering the lower resources of the general exercise program, the expense for a multimodal program is not justified for the secondary prevention of LBP and disability.
