Reaching task 1

Standing in a given area and reaching toward a stationary target at different heights, depths and in different directions

• Reaching length

• Number of targets

• Range of distribution

• Amount of repetition

• Weight shifting

• Functional transitions

Reaching task 2

Standing in a given area and tracking a moving object while extending arm and immersing the hand into the object as it flew in 3D space

• Speed

• Moving range

• Pathway pattern

• Remembered sequence or course of trajectory

• Weight shifting

• Arm coordination

• Advance motor planning

Obstacle avoidance

Standing in a given area and preparing to avoid upcoming obstacles that randomly approached from varying directions by moving body sideways or up/down

• Obstacle hitting ratio

• Speed

• Dual task

• Hitting direction

• Quick change strategy

• Movement adaption

• Agility

Marching

Alternating steps without going forward while following dynamic bars that automatically rose and fell at a predetermined speed and frequency

• Frequency
