Brief Summary
The study will specifically evaluate the potential of the C-Brace to improve the functional mobility and quality of life in individuals with lower extremity impairments due to neurologic or neuromuscular disease, orthopedic disease or trauma, as compared to the stance control orthosis.

Outcome Measures
Primary Outcomes (1)
Six minute walk test (6MWT)
The test measures the distance that the patient can walk on a flat, hard surface, indoors, in a period of 6 minutes. The walk test is patient self-paced and assesses the level of functional capacity. Patients are allowed to stop and rest during the test, however, the timer does not stop. If the patient is unable to complete the time, the time stopped is noted and reason for stopping prematurely is recorded. This test will be administered while wearing a mask to measure oxygen consumption.
Change from baseline in 6MWT using device 1 at 8 weeks and using device 2 at 16 weeks.
Secondary Outcomes (10)
Muscle strength
Change from baseline in muscle strength after device 1 use at 8 weeks and after device 2 use at 16 weeks.
Passive and active range of motion
Change from baseline in range of motion after device 1 use at 8 weeks and after device 2 use at 16 weeks.
10 meter walk test
Change from baseline in gait speed using device 1 at 8 weeks and using device 2 at 16 weeks.
Hill Assessment Index
Change from baseline in hill descent using device 1 at 8 weeks and using device 2 at 16 weeks.
Stair Assessment Index
Change from baseline in stair descent using device 1 at 8 weeks and using device 2 at 16 weeks.
- +5 more secondary outcomes
Other Outcomes (6)
Modified Falls Efficacy Scale
Change from baseline in Modified Falls Efficacy Scale after device 1 use at 8 weeks and after device 2 use at 16 weeks.
Orthotics and Prosthetics User Survey
Change from baseline in Orthotics and Prosthetics User Survey after device 1 use at 8 weeks and after device 2 use at 16 weeks.
World Health Organization Quality of Life, brief form (WHOQOL-BREF)
Change from baseline in WHOQOL-BREF after device 1 use at 8 weeks and after device 2 use at 16 weeks.
- +3 more other outcomes
Study Arms (2)
C-brace then stance control orthosis
EXPERIMENTALStance control orthosis then C-brace
EXPERIMENTALInterventions
The participant will receive 6 sessions of training over a one month period in using the C-brace in all levels of functional gait. The participant will then continue use of the C-brace for one month following training. The C-Brace from Otto Bock is an orthosis that controls throughout stance and swing phases of gait with a micro-processor (MP) controlled knee.
The participant will receive 6 sessions of training over a one month period in using his current stance control knee-ankle-foot orthosis (SCO) in all levels of functional gait. The participant will then continue use of the SCO for one month following training. The SCO controls the knee by maintaining it straight and extended during the stance phase of gait.
Eligibility Criteria
You may qualify if:
- Lower extremity functional impairment due to neurologic or neuromuscular disease, orthopedic disease or trauma.
- Prior active and compliant use of unilateral Knee-ankle-foot orthosis (KAFO) or Stance control orthosis (SCO).
- Age 18 - 80 years.
- Demonstrate a reciprocal gait pattern using the SCO and C-Brace trial tools.
- Cognitive ability to understand and the willingness to sign a written informed consent.
- Subjects must be able to demonstrate the ability to turn the global positioning sensor (GPS) and Actigraph units on and off and sufficient memory ability to wear the devices each day during use of the orthoses.
You may not qualify if:
- Passive ankle range of motion (PROM) of the lower extremity requiring the knee-ankle-foot orthosis (KAFO) of less than 2 degrees.
- Body weight \>275 pounds.
- Unstable neurological or cardiovascular/pulmonary disease, cancer.
- Knee flexion contracture resulting in the inability to actively use C-Brace or SCO.
- Participating in physical therapy currently or within 1 month of starting protocol, specific to orthotic use and gait training.
