Journal Review

What does "m" represent?

• The number of modules

• The number of muscles with EMG data

• The number of subjects in the experiment

• The number of strides taken

If the average muscle weighting was above __%, the module was considered as contributing to the activation of that muscle.

• 90

• 75

• 50

• 40

How many muscle modules did they find and initially use for simulation?

• 2

• 5

• 4

• 3

What is another term for independent groupings of co-active muscles?

• synergies

• multi modal muscles

• joints

• block neural control

What data was collected experimentally?

• EMG and kinematics only

• Ground reaction forces only

• EMG only

• Kinematics, EMG, and ground reaction force data

Why did this paper not originally find 5 muscle modules?

• There was a flaw with their non negative matrix factorization

• They disagreed with the idea of a 5th module

• They did not collect EMG data on the muscles that make up the 5th module

• The simulation could only handle 4 modules at a time

What are the three sub tasks identified in walking?

• balance, trunk stabilization, and leg swing

• forward propulsion, leg swing, and body support

• jumping, gliding, and running

• stance and swing
