The Effect of Exercise on Individuals With Parkinson's Disease

UPDRS part III, is an observer rated clinical measure of motor signs of PD. It is used as a measure of severity of motor signs. We measured this at baseline, 6 , 18 and 24 months. This is a ordinal scale of 0-4 which has 27 items which measures slowness of movement (Bradykinesia), Tremor, Rigidity (muscle stiffness) and postural instabilty. The total value for UPDRS part III scale which ranges from 0 to 108, with a larger number indicating a higher level of impairment.

This was the equivalent amount of dopamine (mg/day) each subject was prescribed based upon all of their PD medications.

This is the MVC for elbow flexion

This is a measure of the MVC for ankle plantar flexion strength

This is a measure of the MVC for elbow extension

This is a measure of the MVC for ankle dorsiflexion

This is a measure of the percentage of the EMG signal that is contained in different frequency bins during a MVC (elbow flexion/extension; ankle DF/PF), a 50% of MVC elbow fleixon contraction, and a 5 NM elbow flexion contraction.

The Integral of the first agonist EMG signal from onset of the agonist EMG signal until peak velocity

The integral of the first 30 msec of the agonist EMG.

the area under the rectified antagonist signal form agonist EMG onset until the end of movement. This reflects the amount of antagonist activation during movement.

Magnitude of the agonist burst reflects the amount of agonist activation during movement.

Time in (ms) for the duration of the first agonist burst during a 72 degree elbow flexion movement and also the percentage of agonist EMG bursts until peak velocity

This is the number of agonist bursts prior to peak velocity.

the amount of agonist and antagonist activity present during limb acceleration.

The integral of the antagonist EMG signal from the onset of the agonist EMG to the end of the movement

Time of the onset of the movement to peak velocity.

This is how fast an individual can perform a 72 degree elbow flexion movement

Time for a subject to passively relax their muscle after performing and isometric contraction to 50% of their MVC

This is the time is takes for an individual to go for rest to a 50% of a MVC contraction as fast as possible.

Spatiotemporal gait analysis using a pressure sensitive walk way allow for measurement of gait velocity, step length, single and double limb support time, cadence, ect.

This is how far an individual can walk in 6 minutes

This is an overall measure of physical fuction

This is the time it takes an individual to get up from a chair, walk 3 meters, turn around and walk back.

This is a overall measure of balance

The distance one can reach forward without taking a step.

This is a test of cognitive function. This test requires individuals to first say as many colors as they can under three different test conditions.

This is a cognitive test of an individuals ability to remember number. It is a test of working memory.

This tests a persons ability to remember that were read to them both forward and then backwards.

PDQ-39 is a composite measure of quality of life in individuals with Parkinson's Disease.

The Epworth Sleepiness Scale is used to determine the level of daytime sleepiness.

This is a self-report rating inventory that measures characteristic attitudes and symptoms of depression.

Time it takes to walk 50 feet

The speed that aerson walks over 50 feet

The time it takes to stand up and sit down five times
