Comparative StudyIncremental ability of needle electromyography to detect radiculopathy in patients with radiating low back pain using different diagnostic criteria.
To determine the incremental ability of different needle electromyography diagnostic criteria to detect lumbar radiculopathy. ⋯ In addition to the presence of positive sharp waves or fibrillations, considering greater than or equal to 30% motor unit action unit potential changes as well as the MiniPM score maintains good specificity and improves the ability of the needle electromyography study to detect lumbar radiculopathy in subjects with radiating low back pain.

Randomized Controlled Trial Comparative StudyAddition of intra-articular hyaluronate injection to physical therapy program produces no extra benefits in patients with adhesive capsulitis of the shoulder: a randomized controlled trial.
To compare the efficacy of intra-articular hyaluronic acid (HA) injections plus physical therapy (PT) with that of PT alone for the treatment of adhesive capsulitis (AC) of the shoulder. ⋯ Intra-articular HA injections did not produce added benefits for patients with AC of the shoulder who were already receiving PT. Thus, the use of intra-articular HA injections for patients with AC of the shoulder should be carefully assessed to reduce unnecessary medical expenditures.

Comparative StudyReliability and validity of step test scores in subjects with chronic stroke.
To establish (1) the intrarater and interrater reliabilities of step test (ST) scores in subjects with chronic stroke, (2) the ST's known-groups validity and cutoff scores for distinguishing subjects with chronic stroke from healthy adults older than 50 years, and (3) the convergent validity of ST scores with lower-limb muscle strength, coordination, balance performance, and walking speed. ⋯ The ST is a reliable measurement tool when the number of steps is counted by either experienced or inexperienced examiners by viewing videotapes. ST scores with both the paretic limb and the nonparetic limb are sensitive in distinguishing subjects with chronic stroke from healthy adults older than 50 years.

Randomized Controlled Trial Multicenter Study Comparative StudySubacromial corticosteroid injection on poststroke hemiplegic shoulder pain: a randomized, triple-blind, placebo-controlled trial.
To evaluate the effect of subacromial corticosteroid injection on hemiplegic shoulder pain (HSP). ⋯ To our knowledge, this is the first randomized, placebo-controlled study to assess the efficacy of subacromial injection in HSP patients with evidence of rotator cuff disorder. Subacromial corticosteroid injection showed improvement in pain, disability, and active range of motion, and the duration of its efficacy continued up to 8 weeks.

Comparative StudyRollator use does not consistently change the metabolic cost of walking in people with chronic obstructive pulmonary disease.
To (1) evaluate whether the use of a rollator changed metabolic cost during a controlled walking task, and (2) explore relationships between the difference in dyspnea and metabolic cost associated with rollator use. ⋯ The mechanism responsible for the amelioration in dyspnea during rollator-assisted walking is multifactorial. A reduction in the metabolic cost of walking may play a part in some, but not all, patients.
