Vastus medialis obliquus and vastus lateralis activity in open and closed kinetic chain exercises in patients with patellofemoral pain syndrome: an electromyographic study.
To evaluate the electromyographic activities of vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles in open and closed kinetic chain exercises in subjects with patellofemoral pain syndrome (PFPS). ⋯ In closed kinetic chain exercises, more selective VMO activation can be obtained at 60 degrees knee flexion. Maximal VMO/VL ratio was observed at this knee flexion angle, and muscle contraction intensity was also greatest.

Neuromuscular electric stimulation in heart transplantation candidates with cardiac pacemakers.
Twenty percent of heart transplantation candidates have cardiac pacemakers. Application of neuromuscular electric stimulation (NMES) in patients with pacemakers is controversial because of potential electromagnetic field interference and subsequent failure of the pacemaker. We present a safety protocol as a procedure before applying NMES in pacemaker patients. ⋯ No changes in the clinical state and no complications secondary to electromagnetic field interference were observed. A check of pacemaker function after this 20-minute stimulation revealed no changes in the pacemaker parameters. After a thorough safety protocol, NMES of knee extensor muscles in patients with pacemakers appears to be safe.

Comparative StudyGender-related differences in acute rehabilitation lengths of stay, charges, and functional outcomes for a matched sample with spinal cord injury: a multicenter investigation.
To examine the effects of gender on length of stay (LOS), treatment costs, and outcomes by using a matched sample of patients with spinal cord injury (SCI). ⋯ Gender was not a significant factor in functional outcome of SCI patients after acute rehabilitation.

Relationships among clinical characteristics of chronic pain after spinal cord injury.
To define relationships among various clinical characteristics of pain occurring after spinal cord injury (SCI). ⋯ Relationships among various clinical features of pain after SCI reveal common clinical patterns important for increased understanding of pain mechanisms and for the design of therapeutic interventions for pain management.
