Peroneal Stimulation for Foot Drop After Stroke: A Systematic Review.

The purpose of this systematic review was to summarize the effect of daily use of single-channel foot drop stimulation among persons with stroke. Randomized controlled trials were searched using electronic databases through May 2014. Six randomized controlled trials were included, involving 820 participants.

Response and prediction of improvement in gait speed from functional electrical stimulation in persons with poststroke drop foot.

Objective: To describe changes in and predictors of comfortable gait speed (GS-C) after using a foot-drop stimulator (FDS; Bioness L300; Bioness Inc, Valencia, CA) for 42 weeks in persons who had sustained a stroke.

Design: Secondary analysis of prospective assessments.

Setting: Multicenter clinical trial.

Suppressed carrier scattering in CdS-encapsulated PbS nanocrystal films.

One of the key challenges facing the realization of functional nanocrystal devices concerns the development of techniques for depositing colloidal nanocrystals into electrically coupled nanoparticle solids. This work compares several alternative strategies for the assembly of such films using an all-optical approach to the characterization of electron transport phenomena. By measuring excited carrier lifetimes in either ligand-linked or matrix-encapsulated PbS nanocrystal films containing a tunable fraction of insulating ZnS domains, we uniquely distinguish the dynamics of charge scattering on defects from other processes of exciton dissociation.

Foot drop stimulation versus ankle foot orthosis after stroke: 30-week outcomes.

Background And Purpose: Drop foot after stroke may be addressed using an ankle foot orthosis (AFO) or a foot drop stimulator (FDS). The Functional Ambulation: Standard Treatment versus Electric Stimulation Therapy (FASTEST) trial was a multicenter, randomized, single-blinded trial comparing FDS and AFO for drop foot among people ≥ 3 months after stroke with gait speed ≤ 0.8 m/s.

Neuroprosthesis peroneal functional electrical stimulation in the acute inpatient rehabilitation setting: a case series.

Background And Purpose: Studies have suggested that peroneal nerve functional electrical stimulation (peroneal FES) during walking improves gait in patients with chronic stroke. The effect of peroneal FES during the acute stages of stroke recovery is not known. The purposes of this case report are: (1) to describe differences between walking with and without a neuroprosthesis during the first few weeks after stroke, (2) to offer a clinical perspective on decision making for the use of peroneal FES during acute rehabilitation, and (3) to determine the feasibility of rehabilitation with peroneal FES neuroprostheses during the acute phases of stroke recovery.

Improving selected hand functions using a noninvasive neuroprosthesis in persons with chronic stroke.

Background And Purpose: Loss of upper extremity function following stroke remains a major rehabilitation challenge. The purpose of this investigation was to determine whether the Handmaster system (NESS Ltd., Ra'anana, Israel) could improve selected hand functions in persons with chronic upper extremity paresis following stroke.

Persons with C5 or C6 tetraplegia achieve selected functional gains using a neuroprosthesis.

Objective: To test the efficacy and safety of the NESS Handmaster neuroprosthesis with subjects with C5 or C6 tetraplegia.

Design: Interventional, nonrandomized case series.

Setting: Subjects' residence and university research laboratory.
