Implanted Peroneal Nerve Stimulator Treatment for Drop Foot Caused by Central Nervous System Lesion: A Twelve-Month Follow-up of 21 Patients.

OBJECTIVE: Drop foot is a common impairment following stroke or other causes of central pathology. We report data on patient self-perceived performance, satisfaction with performance, walking ability, and adverse effects after surgical implantation of the ActiGait® drop foot stimulator. DESIGN: Prospective case study with a 12-month follow-up. SUBJECTS: Twenty-one participants with drop foot caused by central nervous system lesion. METHODS: The patients' self-perceived performance and satisfaction with performance were evaluated using the Canadian Occupational Performance Measure (COPM). Walking ability was assessed using a 10-m walk test and a 6-min walk. Nerve conduction of the peroneal nerve was examined in 10 patients. RESULTS: At follow-up, COPM self-percieved performance from 3.2 to 6.7 points, the median increase being 2.8 (interquartile range (IQR) 2.2-5.0), p < 0.001. Likewise, the COPM satisfaction with performance increased from 2.6 to 6.9 points, the median increase being 4.2 (IQR 2.8-5.8), p < 0.001. Walking velocity increased 0.1 m/s from a baseline measurement of 0.73 m/s (95% confidence interval (95% CI) 0.03-0.2), n = 21, p < 0.01, and walking distance increased by 33 m, from a baseline measurement of 236 m (95% CI 15-51), n = 21, p < 0.001. CONCLUSION: Stimulation of the peroneal nerve by an implantable stimulator increases self-perceived performance, satisfaction with performance, and ambulation in patients with long-lasting drop foot caused by a central nervous system lesion.

Acute Ischemic Stroke in Late Pregnancy Treated with Intravenous Thrombolysis and Endovascular Therapy.

Pregnancy has usually been an exclusion criterion in clinical trials with thrombolysis and endovascular therapy in acute ischemic stroke. For that reason, these therapies are not recommended causing lack of evidence and vice versa. In this case report, we describe a pregnant woman in week 33 + 3 presenting with acute ischemic stroke, which was successfully treated with systemic thrombolysis and endovascular therapy, resulting in a good clinical outcome for both mother and child. The altered fibrinolytic system and the risk factors related to pregnancy constitute a challenge for clinicians when choosing the most suitable treatment modality for treating acute ischemic stroke in pregnancy. It is still uncertain whether thrombolysis in combination with endovascular therapy or endovascular therapy alone is the most appropriate treatment option. However, there is slowly growing evidence that thrombolysis and thrombectomy in pregnancy are feasible and safe with a good clinical outcome for both the mother and the child.

A case of isolated neck extensor myopathy responding favorably to immunotherapy.

We report on a case of a 79-year-old man with dropped head syndrome, where diagnostic tests, ruling out other differential diagnoses, confirmed the relatively rarely occurring condition known as isolated neck extensor myopathy. Biopsy of the neck extensor musculature was with classical pronounced fibrosis, without signs of myositis. The patient was treated with 3 cycles of corticosteroids with pronounced clinical improvement of his symptoms. This emphasizes the importance of considering isolated neck extensor myopathy as a differential diagnosis when encountered with a patient with dropped head syndrome and the importance of trying therapy with corticosteroids even when myositis is absent.
