The effects of surface inclination on gastrocnemius, soleus and tibialis anterior muscle activation during gait.

Background: Inclined walking is associated with multiple musculoskeletal benefits and is considered a therapeutic exercise. Various patterns of increased and decreased muscle activation with inclined surfaces have been observed in normal muscles, with more focus on the proximal lower limb musculature.

Objective: The aim of this study was to assess the differences in electromyographic activation of gastrocnemius, soleus, and tibialis anterior at various inclined surfaces during gait.

Computationally efficient fully-automatic online neural spike detection and sorting in presence of multi-unit activity for implantable circuits.

Background: Spike sorting is a basic step for implantable neural interfaces. With the growing number of channels, the process should be computationally efficient, automatic,robust and applicable on implantable circuits.

New Method: The proposed method is a combination of fully-automatic offline and online processes.
