Upper Extremity Motor Learning among Individuals with Parkinson's Disease: A Meta-Analysis Evaluating Movement Time in Simple Tasks

Table 4

Description of the motor learning paradigms in the studies used in the meta-analysis.

Study	Type of task	Duration of practice	Frequency of practice trials
Agostino et al. (2004) [21]	Visually guided motor sequence in free space.	100 motor sequences trials.	1 session/day (Monday to Friday).; 2 weeks of 5 sessions/week.
Behrman et al. (2000) [22]	Two simple sequential arm-reaching tasks between targets 12.7 cm apart.	120 reaction time trials.	1 session on each of 2 days.
Majsak et al. (2008) [23]	Reaching a ball in front of person.	5 blocks of 4 trials with blocks of stationary, moving, or drop ball conditions.	90 minutes, approximately.; 1 session.
Marinelli et al. (2009)^a [18]	Reach on digitized tablet to a rotating target from center.	48-second blocks of two tasks: with and without rotation.	1 session.
Marinelli et al. (2009)^b [18]	Reach on digitized tablet. Counterclockwise predicted. Clockwise not predicted.	90-second blocks of each of two tasks: predictable and unpredictable.	1 session.
Platz et al. (1998)^c [4]	Pointing from starting position to target 20 cm away.	15 trials baseline, 100 trials practice, and 15 trials with each limb.	1 session.
Platz et al. (1998)^d [4]	Pointing from starting position to target 20 cm away. Timing cues provided.	15 trials baseline, 100 trials practice, and 15 trials with each limb.	1 session.

Note: ^a and ^b are data from two different paradigms within one publication.
^c and ^d are data from two different experiments within one publication.
