Úgy tűnik, hogy a cikkhez hasonló környezetben a "session" a páciensek fizikai terhelésének egy-egy időszakát, szakaszát jelenti, miközben/miután mérik a vizsgálat szempontjából fontos jellemzőket. Pl. a "single session exercise"-nál egy terhelési szakasz, az "8 session exercise"-nál 8 terhelési szakasz van.

Objective: To assess the efficacy of electromyogram (EMG)-triggered neuromuscular stimulation (EMG-stim) in enhancing upper extremity motor and functional recovery of acute stroke survivors. Design: A pilot randomized, single-blinded clinical trial. Setting: Freestanding inpatient rehabilitation facility. Patients: Nine subjects who were within 6 weeks of their first unifocal, nonhemorrhagic stroke were randomly assigned to either the EMG-stim (n = 4) or control (n = 5) group. All subjects had a detectable EMG signal (>5μV) from the surface of the paretic extensor carpi radialis and voluntary wrist extension in synergy or in isolation with muscle grade of <3/5. Intervention: All subjects received two 30-minute sessions per day of wrist strengthening exercises with EMG-stim (experimental) or without (control) for the duration of their rehabilitation stay.

…The Boxing class is a cardio based program so great for fat stripping. The first class is free to try out with no obligations and no joining fees if you don't like it you don't have to come back but I guarantee it will be lots of fun and that is what exercise is all about. The sessions run for 45min - 1 hour and after the first one it is $20 each session or $100 up front for 8 sessions (Boxing is an extra $5 each session).
