We present here a descriptive article on the development of a national quality system for neuromodulatory techniques in the Netherlands. In 1994, due to reimbursement difficulties in the Netherlands, a Neuromodulation Working Group (WGN) undertook an initiative to develop a national quality system for neuromodulation. It was believed that with official recognition of neuromodulation as a therapy by the health authorities in the Netherlands, a quality system for monitoring would then follow. ⋯ We therefore conclude that developed quality systems can provide a basis for medical specialists to cooperate around groups of patients or diseases. These quality systems can facilitate implementation and innovation within the health care system. The role of medical specialists and their will to cooperate is essential.

The objective of this study was to objectively assess the physical activity of daily living in chronic pain patients treated with spinal cord stimulation (SCS). Changes in pain and spontaneous physical activity following SCS were evaluated under real life conditions. Five series of measurements were performed before the implant (baseline) and at one, three, six, and 12 months after the implantation of an SCS system. ⋯ The average total walking distance increased up to 389% at 12 months, reaching statistical significance (p < 0.05) after three months. The stride length and the speed increased (p < 0.01) at all times. We conclude that the reduction in pain intensity due to SCS is associated with a progressive and sustained improvement in physical activity. j.

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.

In recent years, part of the muscle resistance in spastic patients has been explained by changes in the elastic properties of muscles. However, the adaptive spinal mechanisms responsible for the exaggeration of stretch reflex activity also contribute to muscle stiffness. The available data suggest that no single spinal mechanism is responsible for the development of spasticity but that failure of different spinal inhibitory mechanisms (reciprocal IA inhibition, presynaptic inhibition, IB inhibition, recurrent inhibition) are involved in different patients depending on the site of lesion and the etiology of the spastic symptoms. ⋯ This is ensured by increasing transmission in several spinal inhibitory pathways. In spastic patients, this control is inadequate, and therefore stretch reflexes in antagonist muscles are easily evoked at the beginning of voluntary movements or in the transition from flexor to extensor muscle activity. This problem is contradicted by the fact that antispastic therapy to improve voluntary movements should be directed.

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.
