During the assessment of LBP, practitioners must also consider less common causes of pain in that region. For instance, patients with indolent or nighttime pain may have infectious or malignant processes. Referred pain from injuries to pelvic musculature or abdominal contents should be considered, especially following a traumatic event. One of these injuries, which can present as acute low back pain, is rupture of the proximal hamstring tendon. On rare occasion, concomitant LBP, radiculopathy, and hamstring ...

We have found that it is feasible to record from dozens of single units in the motor cortex for extended periods of time and that these signals can be decoded in a closedloop, real-time system to generate goal-directed behavior of external devices. This work has culminated in a FDA clinical trial that has demonstrated that a tetraplegic patient can voluntarily modulate motor cortical activity in order to move a computer cursor to visual targets. Further advances in BMI technology using non-human primates have focused on using multiple modes of control from signals in different cortical areas. We demonstrate that primary motor cortical activity may be optimized for continuous movement control whereas signals from the premotor cortex may be better suited for discrete target selection. We propose a hybrid BMI whereby decoding can be voluntar...

In comparison to the Vicodin group, patients on Darvocet N-100 had significantly fewer requests for prn pain medication each day (3.1 vs. 1.1, p < 0.01), significantly better FIM gains better (18.9 vs. 24.1, p < 0.05), and fewer side effects (nausea and constipation). {\it } Choosing the right pain medication is imperative for achieving optimal efficiency in clinical pathways for orthopedic rehabilitation. In this pilot study, Darvocet N-100 is the preferred narcotic over codeine and its derivatives.

Forty-nine stroke survivors and their caregivers were randomly assigned to treatment as usual or treatment as usual plus the telephone intervention. Global outcomes are reported for health care utilization, family functioning, and general functioning. Family and general functioning were positively and significantly changed at 3 and 6 months. Health care utilization was positively and significantly changed at 3 months. Findings suggest that the model has the potential to decrease health care utilization and improve quality of life for stroke survivors and their caregivers. Further study is warranted.
