Conditioning and recovery of functions lost by brain damage.
The muscle spindle is a receptor apparatus in striated muscle that is necessary for voluntary muscle movement. Paralysis victims lose the feedback of this receptor and cannot initiate motor responses. Four hemiplegic patients were trained to use auditory feedback from electromyographic recordings to initiate activity in paretic limbs. With the addition of visual feedback and the use of the auditory signal as a reinforcing stimulus, the patients' muscle activity was then shaped to approximate normal movement.
Effect of ibuprofen dosage on patient response in rheumatoid arthritis.
In a 4-week double-blind trial in 41 patients with rheumatoid arthritis, ibuprofen (Motrin) decreased the swollen joint count significantly at a dosage level of 2400 mg/day, but not at 1200 mg/day. Ibuprofen probably does have antiinflammatory effects in man, but only at higher dosages; antiarthritic activity at lower dosages reflects primarily analgesia and perhaps antipyretic effects. Complaints and clinical laboratory findings did not differ significantly between the dosage groups.
