Summary
The adjustable iFIT transtibial prosthesis significantly improved patient satisfaction and temperature perception compared to conventional devices. This immediate-fit system shows promise for enhanced prosthetic care.
Area of Science:
- Prosthetics and Orthotics
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Transtibial limb loss necessitates prosthetic devices for mobility.
- Conventional prosthetics can present challenges in fit and comfort.
- Adjustable, immediate-fit systems offer a potential alternative to traditional fabrication methods.
Purpose of the Study:
- To compare patient satisfaction with an adjustable, immediate-fit transtibial prosthesis (iFIT) versus conventionally fabricated devices.
- To evaluate subjective outcomes related to comfort and thermal perception.
Main Methods:
- Prospective, single-group, pre-post intervention study design.
- 24 adult participants with transtibial limb loss were evaluated over two weeks.
- The modified Prosthetic Evaluation Questionnaire (PEQ) was used to assess satisfaction.
Main Results:
- The iFIT system showed significantly higher Modified PEQ scores compared to conventional prosthetics (p < 0.01).
- Participants reported significantly better temperature perception with the iFIT system (p < 0.001).
- No adverse events such as skin breakdown, prosthetic issues, or falls were reported.
Conclusions:
- The adjustable, immediate-fit transtibial prosthesis (iFIT) significantly enhances patient satisfaction and thermal perception.
- These findings support the efficacy of immediate-fit adjustable prosthetic systems.
- Further international, long-term studies are ongoing to assess durability and efficacy in diverse populations.
