Does the physical work capacity of subjects with early osteoarthritis of hip and knee decline in five years?

37± 2were calculated respectively.Mean force time integral figures (inNewton s) at normalwalking speedwere 136± 14, 60± 6, 43± 2 and 19± 1 respectively. Conclusion(s): Calculated numbers can be considered as the first estimate of normative figures for clinical practice, but must be used with caution, because of the diversity of measurement equipment and procedures. Implications:Based on thesemean values in combination with the variance (SE) clinical thresholds can be calculated to identify local pressure points at the foot, that may be at risk for harm or pressure injuries.
