NCT ID: NCT06258343 Recruiting - Amputation Clinical Trials

Extremity Thermographic Values in Individuals With Transtibial Amputation

Start date: May 20, 2024
Phase:
Study type: Observational

The goal of this observational study is to compare thermographic values in the knee region of the healthy extremity and the amputated extremity and learn about the relationship between thermographic value and pain in the knee region of the amputated extremity. The main questions it aims to answer are: 1. Do thermal values in the knee region of the amputated extremity and the intact extremity differ in individuals with transtibial amputation? 2. Is there a relationship between the pain felt in the knee region of the amputated limb and the difference in thermal values between the extremities in individuals with transtibial amputation?

NCT ID: NCT05124873 Completed - Amputation Clinical Trials

Moisture Management Liner At-Home Evaluation

Start date: May 12, 2021
Phase: N/A
Study type: Interventional

The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by nonbreathable and non-thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to passively conduct heat from the skin using thermally conductive elastomers. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.

Moisture Management Liner Effectiveness Study

Start date: July 1, 2020
Phase: N/A
Study type: Interventional

The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by non-breathable and non- thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to remove sweat from the skin and out of the socket and to passively conduct heat from the skin using thermally conductive elastomers. This liner has been developed to work alongside a thermo-electric cooling (TEC)-based module called the Intrasocket Cooling Element (ICE) developed in a parallel project by Vivonics, Inc. and Liberating Technologies, Inc. The ICE device can be embedded into the prosthesis in order to cool the residual limb. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.

NCT ID: NCT04155762 Completed - Prosthesis User Clinical Trials

Effects of Pin and Vacuum Assisted Suspension Systems

Start date: February 1, 2015
Phase: N/A
Study type: Interventional

This study was performed to determine the presence of any difference between Pin Suspension (PS) and Active Vacuum Suspension (AVS) on walking capacity, functional mobility, weight bearing in the prosthetic side, prosthetic satisfaction and body image were evaluated. Nine patients who don't have an obstacle to both socket applications in terms of stump height, type and edema were evaluated in this study. Both suspension systems were administered to the patients included in the study. First, amputees have used PS for 3 months following alignment of the prosthesis and training period. Then again they used AVS for 3 months following alignment of the prosthesis and training period. For each system, after adapting prosthesis 'LASAR posture' was used to evaluate weight bearing on the prosthetic side, '6 Minute Walk Test' for walking capacity, 'Time Up and Go' test for functional mobility, 'Prosthetic Satisfaction Index' for prosthetic satisfaction and 'Amputee Body Image Scale' for body. There were statistically significant difference between PS and AVS in terms of prosthetic side weight bearing percentage, walking capacity, functional mobility and prosthetic satisfaction (p<0.05), in favor of AVS. There were not statistically significant difference between the body image scores (p>0.05). From the view of function and prosthetic satisfaction, AVS was found to be more effective in transtibial amputees. It is believed that our study will be a guide to the future studies including higher number of amputees, different amputation levels and different suspension systems.

NCT ID: NCT04114175 Completed - Exercise Training Clinical Trials

Spinal Stabilization Exercises in Individuals With Transtibial Amputatıon

Start date: September 1, 2019
Phase: N/A
Study type: Interventional

Lower extremity amputation causes rapid changes in musculoskeletal system. With the effect of these changes, the energy requirement for prosthetic ambulance is much higher than normal ambulance. Although methods such as the reduction of the segmental load of the prosthesis and the preference of the different prosthetic components for energy expenditure have been emphasized, the effect of exercise types has not been investigated in our knowledge. Therefore, the aim of the current study is to investigate the effect of spinal (Core) stabilization exercises on energy expenditure in combination with the classical physiotherapy program in patients with unilateral transtibial amputation. Individuals with transtibial amputation included in the study will be randomly divided into two groups. In group 1, basic exercises related to amputation will be applied for 8 weeks and in group 2 basic exercises with spinal stabilization exercises will be applied to the individuals. At the beginning and at the end of the exercise intervention, energy expenditure and exercise capacity will be evaluated by a portable exercise test device during '6 Minutes Step Test'; fatigue assessment will be done before and after 6 Minutes Step Test with 'Modified Borg Scale'; the strength of deep spinal muscles will be evaluated with 'Stabilizer'; dynamic balance and functional mobility will be evaluated by 'Timed Up & Go' Test; and the effect of the prosthesis on mobility will be evaluated by the sub-scale 'Mobility' of 'Prosthetic Evaluation Questionnaire'.

NCT ID: NCT03722797 Terminated - Amputees Clinical Trials

Physical Activity in Adults With Amputation

Start date: May 11, 2017
Phase:
Study type: Observational

This cross-sectional study explores physical activity and energy expenditure among inactive adults with a unilateral transtibial amputation. Results may assist with physical activity prescription for adults with unilateral lower-limb loss.

Comparing Running-Specific and Traditional Prostheses During Running: Assessing Performance and Risk

Start date: August 2016
Phase: N/A
Study type: Observational

The purpose of this research is to provide clinically, administratively, and field-relevant objective running outcomes by directly comparing running biomechanics of individuals with lower extremity amputation (ILEA) using RSPs (Running Specific Prostheses) and traditional prostheses. Within this purpose, the project has two specific aims: Specific Aim 1: To compare RSPs and traditional prostheses with respect to running ability and performance Specific Aim 2: To compare RSPs and traditional prostheses with respect to injury risks associated with running Hypothesis 1a: RSPs will outperform traditional prostheses at all velocities as measured by kinetic data (ground reaction forces, joint powers, joint and limb work) and 50m dash time. Hypothesis 1b: ILEA intact limbs and able-bodied control limbs will outperform residual limbs with RSPs and traditional prostheses at all velocities as measured by kinetic data. Hypothesis 2: Running with RSPs will show reduced acute and chronic injury risks compared to traditional prostheses at all velocities as measured by loading rates, EMG amplitudes, lumbopelvic kinematics, and modeled joint loads.
