Note: Patterned Sensory Enhancement (PSE) is a technique that uses the rhythmic, melodic,
harmonic and dynamic-acoustical elements of music to provide temporal, spatial, and force
cues for movements that reflect functional exercises and activities of daily living. PSE is broader
in application than Rhythmic Auditory Stimulation (RAS), because it is (a) applied to movements
that are not rhythmical by nature (e.g., most arm and hand movements, functional movement
sequences such as dressing or sit-to-stand transfers) and (b) it provides more than just
temporal cues. PSE uses musical patterns to assemble single, discrete motions (e.g., arm and
hand movements during reaching and grasping), into functional movement patterns and
sequences. PSE cues movements temporally, spatially, and dynamically during training
exercises.
The patient walks (i.e., gait trains) using the music therapy informed compositions to achieve
"entrainment"; the repetition of the gait training aids in the reconditioning of neural pathways
("neuroplasticity"). The Histogram screen is the preferred biofeedback as it illustrates when
entrainment occurs; in other words, when the footfalls (steps) register within the step targets
for a steady period of time.
When the gait training session with music therapy is complete, a report documents the song
title, starting bpm, and the percent change of the song tempo in addition to showing all the
important gait parameter measures of: gait speed, step length, step length variability, and
such.
