The Effect of Visual Feedback on Function, Stability and Quality of Life in Transtibial Amputation

Investigation of the Effect of Visual Feedback on Function, Stability and Quality of Life in Individuals With Transtibial Amputation

This study was conducted to examine the effect of visual feedback on function, stability and quality of life in transtibial amputees. A total of 24 subjects who had unilateral transtibial amputations, used prosthesis with total surface bearing socket (TSB) for at least 1 year and volunteered to participate in the study were included. Before and after Treatment subjects were evaluated with "LASAR Posture" for prosthetic weight bearing (PWB), "Berg Balance Scale (BBS)" and "Timed Up& Go Test (TUG)" for balance and functional mobility, "2-Minute-Walk-Test (2MWT)" for physical performance, "Satisfaction with the Prosthesis Questionnaire (SATPRO)" for prosthetic pleasure and "Nottingham Health Profile (NHP)" for health- related quality of life. Participants were randomly divided into two equal groups as study and control groups. After the evaluations the same exercises; PWB exercises, balance exercises, anteroposterior and lateral weight shifting, obstacle course, walking on different grounds were applied to the the study group with visual feedback methods and control group.

Inclusion criteria: had transtibial amputation >18 years old had total surface bearing socket at least one year Outcome measures: Prosthetic weight bearing Berg Balance Scale Timed up &go Test 2 Minute Walk Test Satisfaction of prosthesis questionnare Nottingham health profile

participants in the experimental group were applied usual prosthetic rehabilitation with visual feedback methods. 9 sessions for three days were applied.

participants in the control group were applied usual prosthetic rehabilitation. 9 sessions for three days were applied.

in the study group, subjects were applied for example prosthetic weight bearing exercises in front of the mirror. They watched their reflected image while doing exercises.

minimal (Min WB) and maximal (Max WB) values were visually recorded on the amputated side for three consecutive minutes. The average weight bearing on the amputated side (Ml) was calculated by dividing the sum of maximal and minimal weight bearing values by two. The percentage of total body weight (TBW) borne through the amputated limb was then determined using the formula: (Ml/TBW) x 100

Inclusion Criteria: had unilateral transtibial amputations, used prosthesis with total surface bearing socket (TSB) for at least 1 year volunteered to participate in the study Exclusion Criteria: had any neurological disorders had any cognitive problems
