Bathroom scales have been used for weight bearing (WB) purposes for many years. The physical therapist usually instructs the patient to step on the scale, remember the feeling of a certain weight, and try to reproduce it when moving around with crutches.
However, the quantitative data obtained from scales cannot be easily applied in a dynamic situation, since static WB has little to do with weight distribution during walking . Hence, most patients are unable to internalize and replicate their WB statuses correctly. [2-5]
Moreover, several studies have shown that patients in the early stages of rehabilitation tend to put twice the recommended weight on the involved leg [4, 5], which can delay healing processes and result in re-injury.
Therefore, the use of bathroom scales as a way to learn and maintain proper WB levels throughout the recovery process is questioned – especially when the amount of weight borne through the leg should be minimal.
