Low balance confidence occurs when an individual perceives they have limited ability to maintain their balance while performing a specific task of daily living. It is a prevalent problem in lower limb prosthesis users and is a strong predictor of prosthesis use and community participation. Balance confidence is not necessarily related to functional abilities. It is possible to improve functional ability as a result of rehabilitation, without concurrently improving balance confidence. Interventions to address low balance confidence may need to target both functional abilities as well as beliefs regarding these abilities. The purpose of this study is to test whether, for users of lower limb prostheses, an intervention combining physical therapy exercise to improve function with cognitive behavioral therapy to address fears and thoughts associated with low confidence can improve balance confidence and promote community participation.
Lower limb prosthesis users, with self-reported low balance confidence complete baseline gait analysis and balance testing, as well as a series of validated self-reported outcome scales addressing balance confidence, quality of life, and community integration. Participants are then provided a step activity monitor (SAM) and a global position sensing (GPS) tracker to be worn for one week, the data from which is linked and used to objectively quantify baseline community participation. At the conclusion of the one week, participants are randomized to one of two groups, each of which will last for 8 weeks. At the conclusion of the eight weeks, participants repeat baseline assessments and are again provided a SAM and GPS tracker to wear for one week. Baseline measures and activity monitoring occur again 8 and 16 weeks thereafter.

| Weekly exercise sessions with physical therapist and psychologist | Behavioral | Eight weekly sessions integrating techniques from physical therapy and cognitive behavioral therapy. At the start of each session participants play virtual reality games that target balance and functional gait and then discuss their balance confidence and activity avoidance behaviors with a behavioural counselor. Weekly homework assignments ask participants to report on thoughts causing them to avoid activities and to slowly engage in activities that present increasing levels of fear. |

The scale measures the extent to which emotional problems interfere with work and daily activities on a scale of 0-100 with higher scores indicating less interference |
| 24 weeks |
| Extent of Participation scale from the Measure of Community Reintegration of Servicemembers | The scale measures community participation in terms of how often an individual engages in certain activities on a score of 10-70 with higher scores indicating greater participation | 24 weeks |
| Perceived Limitation scale from the Measure of Community Reintegration of Servicemembers | The scale measures self-perceived limitations in community participation n a score of 10-70 with higher scores indicating less limitation | 24 weeks |
| Frenchay Activity Index | This is a behavioral scale that primarily measures social participation, as well as daily activities on a score of 0-45 with higher scores indicating greater social activity. | 24 weeks |
| Change from baseline in Activity-specific balance confidence scale following the intervention | The ABC scale measures balance confidence on a scale of 0-100 with higher values indicating greater confidence | 8 weeks |
| Activity-specific balance confidence scale | The ABC scale measures balance confidence on a scale of 0-100 with higher values indicating greater confidence. Measurement at this time point will indicate the lasting impact of the intervention on balance confidence | 24 weeks |
This scale measures measures balance function by assessing the performance of functional tasks. It is scored from 0-45 with high scores indicating better balance.
