IM ABLE 2: Injuries Managed With Advanced Bracing for Lower Extremities (IM ABLE 2)
The IM ABLE 2 Study: Long Term Outcomes to Advance Care for Warriors and Veterans Using Advanced Ankle Foot Orthoses
Tutkimuksen yleiskatsaus
Tila
Yksityiskohtainen kuvaus
The purpose of the study is to test different categories of ankle foot orthoses (AFOs) with patients who have had lower limb salvage, reconstruction or other problems impacting limb function. Some lower limb AFO users will decide later to amputate the affected limb to escape pain and repeated surgery requiring them to use a prosthesis instead. Benefits may include reduced pain and more function from a prosthesis.
This research will allow physicians, physical therapists, orthotists, and researchers to determine what modifications can be made to AFOs to make them more comfortable and usable. Over the course of a year, subjects will test both AFO types; a conventional (standard) AFO and an advanced (energy storing and return) AFO, in a battery of physical tests, community use, and surveys to gain a better understanding of the pros and cons of each.
Subjects will be recruited to participate in research for approximately 18 months. During the first six weeks (up to three weeks on each type of AFO), subjects will be provided with an AFO and given training on how to correctly use and maintain it, to ensure optimal use. Over the following 12 months, there will be monthly assessments including questionnaires, activity monitor uploads, device failures, and interviews to gather information on the subject's experience with AFO use.

Active Comparator: Conventional Ankle Foot Orthosis (AFO)
Limited function; thermoplastic or thermoset material
|
Subjects will be initially fit with the AFO category they do not use on a daily basis to ensure they have both AFO categories for the study.
Conventional Ankle Foot Orthoses have been more commonly used in past decades.
AFOs within the conventional category generally include designs that will not return stored energy in late stance.
These designs may vary in material construction and componentry.
For instance, mechanical joints can be incorporated but do not have to be for inclusion in this group.
AFOs in this category may be thermoplastic materials or thermoset laminate.
The devices may be off-the-shelf or custom molded to the patient.

Active Comparator: Advanced Ankle Foot Orthosis (AFO)
Return stored energy; laminated; may include posterior struts; higher activity
|
Subjects will be initially fit with the AFO category they do not use on a daily basis to ensure they have both AFO categories for the study.
These "advanced" AFOs have been developed to offer energy-storing-and-returning (ESR) properties to the user.
Advanced Ankle Foot Orthoses include designs that are widely believed to return stored energy in late stance.
These designs are laminated and may include posterior struts.

Aikaikkuna |
|---|---|---|

Timed Up & Go
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
The Timed Up& Go (TUG) assesses mobility.
In this test, subjects are timed while they rise from a chair, walk 3m, turn around, return to the chair and sit down again.
Subjects are usually permitted to use a walking aid, but not to use physical assistance.
|
After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
|
Two-minute Walk Test
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
The Two-minute Walk Test (2MWT) assesses walking ability.
Subjects will be asked to walk the greatest distance they can in 2 minutes while walking a 15.2m 'out and back' course until asked to stop.
The distance walked will be recorded as will the post-test rate of perceived exertion (6-20 Borg RPE scale).
|
After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
|
Four-Square-Step-Test
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
The Four-Square-Step-Test is a balance and agility test where the patient changes direction quickly while maintaining balance.
A 1-inch-high obstacle in the shape of a Maltese cross is placed on the floor.
The patient is instructed to begin in the back, left quadrant then to move 1) forward, 2) sideways right, 3) backward, then 4) sideways left, then to move in the reverse direction back to the original square.
They move as fast as possible through their movement progression while always keeping one foot on the floor.
|
After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
|
Activities-Specific Balance Confidence Scale
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
The Activities-Specific Balance Confidence Scale (ABC Scale) is a 16-item self-report tool that measures an individual's confidence in performing daily activities without losing balance or feeling unsteady.
Participants rate their confidence for each activity on a 0% to 100% scale where 0% indicates no confidence and 100% indicates complete confidence.
|
After 3-week accommodation period with device A and after 3-week accommodation period with device B.
|
|
Patient-Reported Outcomes Measurement Information System (PROMIS)
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B. Monthly for 12 months after accommodation period with device B.
|
The Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PROMIS-PI) is a standardized, self-reported tool designed to assess the extent to which pain disrupts a person's daily activities and quality of life.
The PROMIS-PI evaluates the impact of pain on social, physical, emotional and cognitive functioning.
Responses are rated on a 5-point scale from "never" to "very much" regarding how pain interfered with activities in the past week.
|
After 3-week accommodation period with device A and after 3-week accommodation period with device B. Monthly for 12 months after accommodation period with device B.
|
|
Orthotics and Prosthetics Users' Survey (OPUS)
Aikaikkuna: After 3-week accommodation period with device A and after 3-week accommodation period with device B. Monthly for 12 months after accommodation period with device B.
|
The OPUS is a self-report questionnaire consisting of five modules.
The following four modules related to the lower extremity will be used: 1) Lower Extremity Functional Status Measure, 2) Health Related Quality of Life Index, 3) Satisfaction with Devices and 4) Satisfaction with Services.
The first two modules are based on a five-point Likert scale and nominal Yes/No scale while the latter two use a four-point Likert scale.
Higher scores indicate better outcomes.

Preference
Aikaikkuna: Before and after each accommodation and training period. At 12 month follow-up.
|
Interviews with participants will be used to identify overall preference and device preference for different activities.
Interviews will also ask about the specific needs, preferences, challenges, and limitations of using each device.
|
Before and after each accommodation and training period. At 12 month follow-up.
|
|
Activity monitoring
Aikaikkuna: Monthly for 12 months after initial two accommodation and training periods
