    With this load-bearing practice condition, the patient learns a new partial weight-bearing level on a set of scales to replicate that weight during walking.

    Although static replication of weight bearing (WB) was only significantly greater (P<.017) than expected for the 20% and 60% BW weight-bearing conditions, patients exerted more than 5% BW over the exp

    Although static replication of weight bearing (WB) was only significantly greater (P<.017) than expected for the 20% and 60% BW weight-bearing conditions, patients exerted more than 5% BW over the expected target for the 20%, 40%, and 60% BW weight-bearing trials. Patients were within 5% BW for the 80% BW weight-bearing static condition.

    Immediate dynamic replication of weight bearing (WB) was significantly greater (P<.017), and more than 5% BW over the expected target for 20%, 40%, and 60% BW weight-bearing trials, but dynamic replication was within 5% BW for the 80% BW weight-bearing condition. Dynamic replication of weight bearing improved (P<.017) over a 7-day retest period for the 20% BW weight-bearing level only.

    Pearson correlations showed that patients who were poor at replicating weight-bearing (WB) restrictions statically were also poor at replication during gait, indicated by a moderately high relationship between static and dynamic weight-bearing replication error across all weight-bearing conditions. A high relationship existed within the 20% and 40% BW weight-bearing levels.
