Objectives
Explain advances in neuroscience and impact on the
field of rehabilitation
Briefly discuss development and data on an efficacious
speech treatment LSVT LOUD
Describe development and key aspects of limb motor
treatment LSVT BIG
Introduce the LSVT HYBRID approach (simultaneous
delivery of BIG and LOUD)
It is an exciting time to be in
rehabilitation today!

Basic science evidence for the value of
exercise in PD (classically drugs, surgery,
today…)

Identified key principles of exercise that
drive activity-dependent neural plasticity

Demonstrated that exercise can improve
brain functioning (neural plasticity) and
may slow disease progression

Exercise is Medicine!

“If only we can hear and understand her”
Family of Mrs. Lee Silverman 1987
5 Stages of Grief
Denial - “There must be some mistake!”
Anger – “I sure got shafted this time.”
Bargaining – “There must be a cure.”
Depression – “This is hopeless.”
Acceptance – “ I can deal with this.”
These stages must be worked through before any
meaningful process can begin.

LSVT Programs
Administered in an intensive manner to
to challenge the impaired system.
Techniques specific to PD-specific deficits!
bradykinesia/hypokinesia
and
kinesthetic awareness
(sensory deficit)
TARGET of LSVT LOUD
Loud is more than a laryngeal event
– spread of effects

(Farley & Koshland, 2005; Farley, Fox, et al., 2008;

What are the fundamentals of
LSVT BIG?
Standardized, research-based, specific protocol
TARGET: Bigness (amplitude)
MODE: Intensive and High Effort
CALIBRATION: Generalization
Sensory
Internal cueing
Neuropsychological changes
TARGET
BIG (Large amplitude whole body movement)
Single Target - Triggers Activation across motor systems
SMALL
BIG
NORMAL “BIGNESS“
MODE
Delivery
– Physical
– Occupational Therapist
• 1:1 intervention
Time of Practice
– 4 consecutive days per week for 4 weeks
– 16 sessions in one month
– 60 minute sessions
– Daily carryover assignments (30 days/entire
month)
– Daily homework (30 days/entire month)
CALIBRATION
MISMATCH between self-perception
of output and how others perceive it
“I had no idea how small my world had
become”
“I can’t move like this, people will think
I am crazy!!”

Conclusions:
• Activity Matters
• LSVT BIG may be especially important for
trunk rotation and balance - everyday
movements
Principles of LSVT applied
simultaneously to the
speech and limb motor systems.
LSVT HYBRID = LOUD + BIG
 Combined or “Hybrid” approach for PD
 May promote greater plasticity through greater
intensity, complexity, saliency
 Enhance practical, logistical, financial costs of
PD rehabilitation
LSVT HYBRID retrains
“normal use”
“In my normal everyday life,
I just exaggerate my movements.
I keep things Big when
I reach for things,
or when I bend or when I walk;
and when I talk –
I keep my voice strong.”

overview of one session
Maximal Daily Exercises Sustained Movements
1. Floor to ceiling
2. Side to side Repetitive Movements 1. Step and reach forward 2. Step
and reach sideways
3. Step and reach backwards
4. Rock and reach forward-backwards
5. Rock and reach side to side Functional Movements ~ 5 exercises that
are patient driven Ex: Rolling, STS, Walking with turns, picking up
objects, reaching 2. Hierarchy Tasks Recreate real world activities that
are difficult Variable and progressive Ex: Restaurants, movie theaters,
Chores, leisure activities etc 3. Carryover assignments (homework)
Maximal Daily exercise demonstration:
1. Maximal Daily exercise demonstration Refer to handout
2. Maximal Daily Exercises, minimum of 10 reps each
Sustained Movements, repeated 10 times and held for 10s
1. Floor to ceiling 2. Side to side Repetitive Movements 1.
Step and reach forward, 10 each leg 2. Step and reach
sideways, 10 each leg
3. Step and reach backwards, 10 each leg
4. Rock and reach forward-backwards, 2sets of 20
5. Rock and reach side to side, 2 sets of 20 Functional
Movements ~3-5 exercises that are patient driven, repeat 10x
Ex: Rolling, supine to sit, STS, walk and turn, Sit and reach,
stand and reach, walk and pick up object
Maximum Daily Exercise Tips:
• Daily exercises don’t change over 4weeks Increase effort from week to
week Increase reps,
• duration, decrease rest,
• No UE support,
• remove or decrease vision,
• add resistance,
• add dual task Eliminate fear of falling Don’t sacrifice BIGNESS for speed,
• movements are deliberate Count LOUD Stomp “Shape” alignment with
minimal cognitive load Minimal explanations
• “Big arms”, “Big hands”, “Big posture” Replaces:
• “Pull your shoulders back, keep your chest up”, “Extend your wrists”,
“straighten your knees”
• Model movements
• “Do what I do”
Summary
Advances in neuroscience have provided
neurobiological and behavioral evidence supporting the
positive impact of exercise-based protocols in people
with PD
There is a rapidly growing literature in physical
therapy/exercise protocols in humans with PD
LSVT Programs have been developed and studied over
the past 20 years
LSVT BIG is one type of physical therapy program that
has potential to offer improvements in movement and
quality of life for people with PD
