During the course of rehabilitation hemiplegic patients who have Chedoke McMaster Stages of Motor Recovery scores 4 and 5 measured three weeks after onset of stroke often improve their arm and hand function to the point that they can later use it in the activities of daily living (ADL) (1). These patients can be considered to have mild arm and hand paralysis since they can grasp objects and manipulate them with minor restrictions in the range of movement and force. On the other hand, hemiplegic patients who have Chedoke McMaster Stages of Motor Recovery scores 1 and 2 measured three weeks after onset of stroke, during the course of rehabilitation seldom improve their arm and hand function, and when they do, the improvements are not sufficient to allow these patients to use the arm and hand in ADL (1). ⋯ The treated and control patients had approximately the same time allocated for arm and hand therapy. After the treatment program was completed, the patients treated with the neuroprosthesis significantly improved their reaching and grasping functions and were able to use them in ADL. However, the majority of the control patients did not improve their arm and hand functions significantly and were not able to use them in ADL.

Spinal cord stimulation (SCS) has traditionally been applied to the treatment of neuropathic pain with good to excellent outcomes. Visceral pain syndromes can be just as debilitating and disabling as somatic and neuropathic pain, however, there seems to be a general lack of consensus on appropriate treatment strategies for these disorders. We present here several case studies to demonstrate the viscerotomal distribution of abdominal visceral pain pathways and the application of traditional SCS techniques for its management. ⋯ There was an overall mean reduction of 4.9 points in the VAS score for pain intensity and a substantial (> 50%) decrease in narcotic use. All patients were followed for more than one year with excellent outcomes and minimal complications. We conclude, based on these case reports, that SCS might be an effective, nondestructive, and reversible treatment modality for abdominal visceral pain disorders.

The objective of this study was to evaluate the long-term infection risk from refilling intrathecal drug delivery devices. We studied 25 patients (14 females and 11 males) with intrathecal infusion pumps placed for spasticity (23 patients) and chronic pain (two patients). In this study group there were 890 refill procedures (mean 35.6 ± 20.5; range 8-72 times) performed on an outpatient basis by four different physicians. ⋯ All cultures, in all pumps, were negative for aerobic and anaerobic bacteria. We conclude that periodic refills of intrathecal implanted pumps do not seem to be a risk factor for infection if standard sterile refill procedures are performed. In this study, it was clear that comorbid infections from other parts of the body do not present as a risk for device contamination.
