Patterned Sensory Enhancement (PSE)
A broader application than RAS as it facilitates movement and movement patterns that are not
biologically rhythmical. These movement patterns are incorporated into a series to form
functional movement patterns. For example, hand and arm movements for eating, dressing,
and other ADL's as well as whole body movements required to shift from a seated to as
standing position.
PSE is defined as a technique using rhythmic, melodic, harmonic, and dynamic acoustical
elements of music to provide temporal, spatial, and force patterns to structure and to cue
functional movements. It typically occurs during open-chain parameters of gait.

Fitting the Music to the Steps per Minute
1.
It is important to complete the majority of the music discussion prior to the beginning of
gait training. Typically, the patient will fatigue and the data will not be as accurate during
walking while you are attempting to establish preference/context and set up the music.
2.
Measure a patient's gait speed - On the initial rehab visit, the therapist can determine the
tempo of music to begin the gait training using one of the particular walk tests that apply to
the patient's ability (e.g., 6 MWT, 6 meter walk test). Lower level patients can ambulate for
15 seconds with the therapist counting each heel strike and multiplying the total by four.
The total number will be steps per minute (SPM). Initially, the tempo of music should be a
few beats slower than the initial walk test.
3.
If the calculated steps per minute from the baseline gait test do not match a preset tempo,
adjust the GT3 music bpm first,
following guidelines to choose a song tempo:
a. Choose the song tempo that is at or just below patient's baseline SPM.
b. Tempo change the music upward as a general rule during the treatment phase as you
do 5%-10% incremental increases.
4.
When it is time to start
goal is for the patient to walk step-over-step bilaterally at the established tempo.
5.
Allow the client to walk to this music tempo (bpm) for 3-5 minutes to allow entrainment to
occur during treatment phase.
a. Based on analysis of the person's gait pattern, the therapist will adjust the music (the
therapist must get familiar with music library in order to make distinctions in each
composition to select the appropriate usage of songs). Ex orthopedic vs. those with
cognitive and severe gait impairments such as Animals Everywhere exercise.
