Abstract
Aim: To analyse the two commonly used prosthesis namely the Laminated Exoskeletal Transtibial (TT) Patellar Tendon Bearing socket Prosthesis and the Modular Transtibial Total Surface Bearing Socket (TSBS) Prosthesis for persons with Below Knee amputation in terms of appearance and utility and also to identify the demographics profile in the study group.
Method and Materials: A cross- sectional questionnaire study was designed for 30 unilateral Transtibial (Below Knee) amputees of which 15 were using Laminated TT Prosthesis and 15 were using Modular TT Prosthesis for more than 1year.The study was conducted between Jan 2016 to Dec 2016. Outcome measure- User satisfaction was analysed using Prosthesis Evaluation Questionnaire PEQ- appearance and PEQ -utility scales. Statistical analysis used: Paired T test was used to analyse the results and p value found between the two groups for PEQ-appearance and utility using SPSS version 21 computer software.
Results: 93.3 % (14 subjects) using Modular Prosthesis were satisfied with the utility of their prosthesis compared to only 46.6% (7 subjects) in the Laminated Prosthesis group. Paired T test was statistically significant between two prosthesis group (p value <0.05). 86.6% (13 subjects) using Modular Prosthesis were satisfied with the appearance of their prosthesis compared to only 40% (6 subjects)) in the Laminated Prosthesis group which was statistically significant (p value<0.05).
Conclusion: Comparing Modular Transtibial Prosthesis with conventional laminated Transtibial prosthesis, modular prosthesis is by far superior in terms of utility and appearance.
