Reducing stiffness of shock-absorbing pylon amplifies prosthesis energy loss and redistributes joint mechanical work during walking

Table 1 The four stiffness conditions and their values for each spring set were measured by mechanical testing from Boutwell et al. [23]

Stiffness condition	SOFT (kNm⁻¹)	MED (kNm⁻¹)	NORM (kNm⁻¹)	RIGID (kNm⁻¹)	Average mass (kg)
Spring set 1	68.2	89.3	111.8	3556.9	71.9 ± 5.04
Spring set 2	85.6	111.8	153.8	3556.9	99.1 ± 19.1
