Table 1. Summary of studies evaluating the effectiveness of currently used training methodologies for partial weight-bearing orthopaedic patients.

Authors	Outcome
Tactile Feedback Gray et al. [16]	Feedback method 20 to 30 percent off actual weight, suggesting it is a poor method of weight-bearing training.
Scales Dabke et al. [4]	Neither six healthy volunteers nor 23 post-op lower limb patients were able to reproduce weight bearing while walking with crutches following training with a bathroom scale.
Malviya et al. [18]	Training with bathroom scales leads to retention of static weight bearing at 0 mins and 60 mins in 12 weight-bearing subjects.
Warren et al. [5]	Bathroom scales had little effect on training patients. What little effect that was present rapidly decreased over ensuing days.
Biofeedback Chow et al. [19]	Audio Biofeedback better than conventional bathroom scale for six transtibial amputation patients.
Hershko et al. [12]	Biofeedback training shown to be superior to physiotherapy in 33 post-operative lower extremity orthopaedic patients.
Hustedt et al. [11]	Biofeedback shown to be superior to both bathroom scales and verbal instructions in 20 partial weight-bearing subjects using crutches.
Hustedt et al. [21]	Biofeedback shown to be effective across age groups in 50 weight-bearing subjects aged 20 to 78 years.
Hustedt et al. [34]	Biofeedback training is maintained over a 24-hour period in 10 weight-bearing subjects.
Isakov et al. [32]	Biofeedback shown to be effective in use of partial weight-bearing patients as compared to standard physiotherapy in 42 post-op orthopaedic patients.
Pataky et al. [15]	Biofeedback works in 11 patients after total hip arthroplasty, but patients forget 30 minutes later, as well as at one and two day follow-up.
Vasarhelyi et al. [2]	Neither 23 patients nor 11 healthy volunteers were able to comply with weight-bearing limitation at 3-day follow-up following biofeedback training.
