The associations between the dominant and nondominant peak external knee adductor moments during gait in healthy subjects: evidence for symmetry.
There is growing interest in the role of the knee adduction moment in the pathogenesis of knee pain and osteoarthritis. It is unclear whether the knee adduction moment is similar between the dominant and nondominant legs during locomotion. This study examined whether asymmetry exists in the peak knee adductor moments during gait in healthy adults. ⋯ In healthy subjects, the magnitude of the dominant limb peak external knee adduction moments during stance, and in particular late stance, appears representative of the magnitude of the moment in the nondominant limb. These findings imply symmetry between these moments and may have important implications when collecting data for limb analyses among healthy subjects. Whether gait symmetry protects against the onset of unilateral (or increases the risk for bilateral) pathological joint changes will need to be confirmed longitudinally.

The effects of scapulothoracic bursa injections in patients with scapular pain: a pilot study.
To assess the effects of steroid plus hyaluronate injections for scapulothoracic bursitis in patients with scapular pain. ⋯ Scapulothoracic bursitis should be considered when treating patients with perimarginal scapular pain or subscapular pain. Our findings show that steroid plus hyaluronate injections into the scapulothoracic bursa provide an effective means of treating patients with scapulothoracic bursitis.

A prospective outcome study on the effects of facet joint radiofrequency denervation on pain, analgesic intake, disability, satisfaction, cost, and employment.
To assess the effect of radiofrequency denervation (RFD) on patients with chronic low back pain (LBP) of facet joint origin. ⋯ RFD provides safe and significant short-term improvement in pain, analgesic requirements, function, satisfaction, and direct costs in patients with chronic LBP of facet origin.

Randomized Controlled TrialThe immediate effects of mobilization technique on pain and range of motion in patients presenting with unilateral neck pain: a randomized controlled trial.
To determine the immediate effects on both pain and active range of motion (ROM) of the unilateral posteroanterior (PA) mobilization technique on the painful side in mechanical neck pain patients presenting with unilateral symptoms. ⋯ The results of this study did not provide support for the preference of the unilateral PA mobilization on the painful side to the random mobilization.

Attenuated skin blood flow response to nociceptive stimulation of latent myofascial trigger points.
To investigate the effect of painful stimulation of latent myofascial trigger points (MTrPs) on skin blood flow and to evaluate the relative sensitivity of laser Doppler flowmetry (LDF) and thermography in the measurement of skin blood flow. ⋯ The present study demonstrated an attenuated skin blood flow response after painful stimulation of latent MTrPs compared with non-MTrPs, suggesting increased sympathetic vasoconstriction activity at latent MTrPs. Additionally, LDF was more sensitive than thermography in the detection of the changes in skin blood flow after intramuscular nociceptive stimulation.
