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.

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 effect of prehabilitation exercise on strength and functioning after total knee arthroplasty.
The purpose of this study was to examine the effect of a preoperative exercise intervention on knee pain, functional ability, and quadriceps strength among patients with knee osteoarthritis before and after total knee arthroplasty (TKA) surgery. ⋯ These findings appear to indicate the efficacy of prehabilitation among TKA patients and support the theory of prehabilitation.

Clinical Trial
The significance of multifidus atrophy after successful radiofrequency neurotomy for low back pain.
To determine the presence of lumbar multifidus atrophy and pain after successful lumbar medial branch radiofrequency neurotomy for zygapophysial joint mediated pain. ⋯ This preliminary study provides evidence that successful medial branch RFN for lumbar zygapophysial-mediated pain does cause initial denervation but no discernable segmental atrophy of the multifidus at long-term follow-up. Previous denervation and diffuse atrophy in these subjects was not associated with pain.
