The goal of the project is to explore which elements of rehabilitation that influence mobility in new and experienced unilateral lower-limb amputees.
Both new and experienced unilateral lower limb amputees (LLA) describe difficulties when ambulating intentionally and independently from one place to another using prosthesis. In LLA, this decreased ability to mobilize affect daily functioning and may result in low activity-levels, impeded social participation and reduced health-related quality of life.
Both primary and secondary rehabilitation of LLA have implications for functional mobility. The consensus among health professionals is that LLA should train to improve their ability to ambulate. However, knowledge from research regarding which elements that constitute effective training and how systematic exercise affects body structures, functions, activity and participation in lower limb amputees, is limited.
There also is a lack of knowledge of how prosthetic users endure and process the challenges regarding mobility, how they adapt to the use of their prosthesis, how safe they are ambulating using the prosthesis, and how pain and psychosocial issues affect their perceived health and mobility.
The aim of this Ph.D.-project is to explore how a period of semi-standardized individualized rehabilitation originating from an evidence-based approach, affect the functional mobility of both new and experienced LLA, and how LLA process the loss of a limb and challenges during ambulation.

| Prosthetic Limb Users Survey of Mobility (Plus-M) Short form - 12 items | A questionnaire that measures different aspects of mobility in lower-limb amputees (LLA) using prosthesis. PLUS-M provide a score range from 17.5 to 76.6. High scores indicate better outcome. | 4-8 weeks |
| The Amputee Mobility Predictor (AMP). | The test is designed to measure mobility and ability to move with prosthesis (AMPPro) and without prosthesis (AMPNoPro). AMPPro provide a score range from 0-47. AMPNoPro provide a score range from 0-43. High scores indicate better outcome. | 4-8 weeks |

| Trinity Amputation and Prosthesis Experience Scale-Revised (TAPES-R) - psychosocial adjustment | The questionnaire examines psychosocial processes involved in adapting to the prosthesis as well as specific needs when using prosthesis. Psychosocial adjustment - general subscale, provide a score range from 1.0-4.0. High scores indicative of positive adjustment. Psychosocial adjustment - social subscale, provide a score range from 1.0-4.0. High scores indicative of positive adjustment. Psychosocial adjustment - adjustment to limitation subscale, provide a score range from 1.0-4.0. High scores indicative of positive adjustment. |

| Trinity Amputation and Prosthesis Experience Scale-Revised (TAPES-R) - activity restriction scale | The questionnaire examines psychosocial processes involved in adapting to the prosthesis as well as specific needs when using prosthesis. Activity restriction scale, provide a score range from 0.0-2.0. High scores is indicative of activity restriction. | 4-8 weeks |
| Trinity Amputation and Prosthesis Experience Scale-Revised (TAPES-R) - satisfaction with prosthesis | The questionnaire examines psychosocial processes involved in adapting to the prosthesis as well as specific needs when using prosthesis. Satisfaction with prosthesis - aesthetic satisfaction subscale, provide a score range from 3-9. High scores is indicative of satisfaction with prosthesis. Satisfaction with prosthesis - functional satisfaction subscale, provide a score range from 5-15. High scores is indicative of satisfaction with prosthesis. | 4-8 weeks |
| Activities-Specific Balance Confidence scale (ABC) | The questionnaire measures how confident LLA are in performing ADL without losing balance or becoming unsteady. ABC provide a score range from 0-64. High scores indicate better outcome. | 4-8 weeks |
| EuroQoL 5L - health-related quality of life (EQ-5D-5L) | Standardized generic instrument used to measure health outcomes and health-related quality of life. Each question provide a score range from 1-5. High scores indicate worse outcome. | 4-8 weeks |
