Figure Legend:
Force transmission from the shoulders to the waist in S3 (left) compared with S4 (right); fs(R) and fs(L), respectively, denote the spring force measured from the right and from the left side of the passive module; fc denotes the assistive force provided from the active module; fr denotes the sum of the spring forces in S3 and the sum of the spring and assistive forces in S4; and the assistive forces reduced the peaks of the total transferred force (fr) in S4 compare to S3
