The use of modern information and telecommunication technologies enables telerehabilitation of neurological deficits in the domestic environment. The current state of studies on rehabilitative teletherapy for improvement of motor function and mobility deficits due to stroke is reviewed. Two neurolinguistic proof of concept studies investigating the efficacy of online interactive telespeech therapy are reported, which compared virtual screen to screen interactive telerehabilitation of aphasia after stroke and dysarthrophonia in Parkinson's disease to conventional face to face rehabilitation. The results of the studies indicate that the neurological rehabilitation of motor and communicative deficits in the domestic environment of patients by means of teletherapy is just as efficient as conventional rehabilitation. Under home-based telerehabilitation patient transfer becomes unnecessary. Rehabilitative Teletherapy is a posthospital component of a cross-sector supply chain for patients with handicaps or impairments due to stroke and other neurological diseases.
Patients suffering subarachnoid hemorrhage in whom angiography does not initially show vascular malformation and CT scan rules out an intracranial tumor, have, reportedly, a good prognosis with a rate of recurrent hemorrhage of about 2-10% within a follow-up time of up to 15 years. Most authors denied indication for control angiography. In order to study the benefit of control angiography performed after 4-6 weeks, four-hundred eighty-three patients with SAH but without ICH were reveiwed, and the longterm clinical course of 98 patients with SAH of unknown origin treated in our department between 1976 and 1988 was investigated. Among 183 patients who underwent control angiography, a second angiography showed an aneurysm in 143. The third angiography was positive in a further 18 patients. Recurrent SAH occurred early only in patients who had undergone only one angiography. One patient died from intracerebral hemorrhage of unknown origin two years following SAH. These data support the need for control angiography in cases of SAH.
In a model work place (hand-grip dynamometer), eleven subjects performed rhythmical hand-grip contractions to exhaustion (frequency 30/min). In each working cycle the contraction and rest phases were distinguished. The work to exhaustion was repeated four times (four working periods with 156-min rest intervals). The tests were performed at 40, 60, 80, 100% MVC. Analysis of Variance showed no difference in the group means (mean values of each working period and load level) for the duration of the contraction or rest phases, the integrated bioelectrical muscle activity (iEMG) of flexors, extensors, brachioradialis (iEMG referred to working cycle and contraction phase) or iEMG of the thenar muscles (referring to the working cycle), or in the duration of the R-R interval in the ECG during comparable periods of the experiments. The endurance times decreased from working period 1-4, and a similar decrease occurred in the force-time product. It may be concluded from these results that 15 min rest is insufficient for adequate recovery from hand-exhaustion exercise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
