Effectiveness of a lateral-wedge insole on knee varus torque in patients with knee osteoarthritis.
To test whether a lateral-wedged insole, inclined at 5 degrees or 10 degrees, significantly reduces knee varus torque during walking in patients with knee osteoarthritis compared with both using no insole and with wearing nonwedged control insoles of the same material and average thickness. ⋯ Both wedge insoles are effective in reducing the varus torque during walking beyond what theoretically could be explained by a reduced walking speed or cushioning effect from the insole. These data imply that wedged insoles are biomechanically effective and should reduce loading of the medial compartment in persons with medial knee osteoarthritis. Although the effect of the 5 degrees wedge was smaller, it may be more comfortable than the 10 degrees wedge to wear inside one's own shoes.

Comparative StudyThe use of Rasch measurement to improve the Oswestry classification scheme.
To use Rasch measurement to assess and modify the original classification categories of the Oswestry Low Back Pain Disability Questionnaire (Oswestry), to examine the hypothesis that the items from the Oswestry form a unidimensional construct and a hierarchical representation of low back pain (LBP) disability, and to compare ordinal Likert resultant scores to interval Rasch scaled scores with disability categories serving as a framework. ⋯ Rasch analysis produced disability categories in the Oswestry that are linear and, therefore, useful for quantitatively assessing self-reported disability levels.

ReviewAbrupt withdrawal from intrathecal baclofen: recognition and management of a potentially life-threatening syndrome.
To suggest guidelines for the prevention, recognition, and management of a life-threatening syndrome (high fever, altered mental status, profound muscular rigidity that sometimes progressed to fatal rhabdomyolysis) in patients who experience the abrupt withdrawal of intrathecal baclofen (ITB) therapy. ⋯ Most episodes of severe ITB withdrawal were preventable. Patients at risk can be identified and educated prospectively and given medication for emergency use. Treatment with GABAergic agonist drugs may prevent potentially fatal sequelae.

Randomized Controlled Trial Clinical TrialStep training with body weight support: effect of treadmill speed and practice paradigms on poststroke locomotor recovery.
To investigate the effect of practice paradigms that varied treadmill speed during step training with body weight support in subjects with chronic hemiparesis after stroke. ⋯ Training at speeds comparable with normal walking velocity was more effective in improving SSV than training at speeds at or below the patient's typical overground walking velocity.

Randomized Controlled Trial Comparative Study Clinical TrialSuprascapular nerve block for pain relief in adhesive capsulitis: comparison of 2 different techniques.
To evaluate the clinical effectiveness of 2 suprascapular nerve block techniques in adhesive capsulitis. ⋯ The near-nerve electromyography technique for suprascapular nerve block was more successful in providing and maintaining pain relief for up to 60 minutes.
