Purpose : This article was a quasi-experimental study that applies to external -feedback weight-bearing training among hemiplegic patients with a stoke. Methods : It examined whether position sense and balance can improve fall efficacy and prevent a fall. The subject of study was divided in two; Experimental group had 18 people and control group had 16 people. It took 8 weeks to finish training. Experimental group provides external-feedback weight-bearing training for ten minutes after neurological treatment for 20 minutes and control group provides nerves treatment for 30 minutes. To find the effect of a fall assessed position sense, balance and fall efficacy of the lower limbs before the fact, after 4 weeks and 8 weeks. Results : According to the conclusions, external-feedback weight-bearing training to prevent a fall was more effective intervention in experimental group than in control group. Conclusion : This study suggests that external-feedback weight-bearing training is a intervention to prevent the fall of hemiplegic patients with a stroke effectively.
