简要总结
The below Knee (transtibial) artificial limb (prosthesis) consists of a Socket, Shank and a Foot. Socket is the part which is in direct contact with the residual limb and serves as an interface between the stump and the artificial limb (prosthesis). Shank is the part of the artificial limb, which connects the Socket and the Foot. Lower extremity artificial limb (prosthesis) components are made using a wide variety of materials such as Wood, Plastic, Metal and Carbon fiber.
This study aims to assess the efficacy of incorporating a cost effective material like Cane as a component in the the below Knee artificial limb (transtibial prosthesis). Following fabrication of the prosthetic socket as per current good clinical practices, the Shank and the Foot of the artificial limb would be fabricated with the use of Cane. This may make the prosthesis cheaper, lighter and easy to maintain in the community. In addition, the amputee’s may be able to walk barefoot and squat. The ability to walk barefoot and squat are important with reference to social and cultural practices in India. In the event of a natural disaster, fabrication of a Cane based prosthesis may be easier as compared to conventional prosthesis.
Patients with below Knee amputation would be screened in the Department of Physical Medicine and Rehabilitation for fulfilling the eligibility criteria. Participants must have been community ambulators (walkers) for at-least six months with a conventional below Knee artificial limb (transtibial prosthesis). For those who consent to participate in the study, a Cane based below Knee artificial limb (transtibial prosthesis) would be fabricated. The primary outcome measures which would used in the study (10 meter walk test, 2 minute walk test, Timed up and go test) have been validated. An objective gait analysis would be done in the Gait lab, Department of Physical Medicine and Rehabilitation - initially at first visit with a conventional below Knee artificial limb (transtibial prosthesis) and after 3 weeks of fabrication of the Cane based below Knee artificial limb (transtibial prosthesis). Prosthesis Evaluation Questionnaire (sub-group 1, 4 and 5) would be filled at initial visit and after 3 weeks of fabricating Cane based artificial limb (prosthesis) to assess patient satisfaction and mobility. Data would then be compared and reported.

结局指标
主要结局
2 Two minute walk test It assesses the distance in meters a person is capable of walking in two minutes. Patient is asked to perform at the fastest speed possible.
时间窗: Initial measurement would be done at the first visit with a conventional prosthesis. Following which repeat measurement would be done after 3 weeks of fabrication of the cane based prosthesis.
1 Ten meter walk test. The time taken to walk in seconds is recorded for three trials and average measured.
时间窗: Initial measurement would be done at the first visit with a conventional prosthesis. Following which repeat measurement would be done after 3 weeks of fabrication of the cane based prosthesis.
3 Timed up and go test It measures the duration in seconds necessary to get up from a chair walk three meter go back to the chair and sit down again.
时间窗: Initial measurement would be done at the first visit with a conventional prosthesis. Following which repeat measurement would be done after 3 weeks of fabrication of the cane based prosthesis.
