Development and reliability testing of the Comprehensive High-Level Activity Mobility Predictor (CHAMP) in male servicemembers with traumatic lower-limb loss
Robert S. Gailey, PhD, PT, et al.
We developed a new outcome measure called the
Comprehensive High-Level Activity Mobility Predictor
(CHAMP) that assists clinicians at U.S. Department
of Defense medical treatment facilities and
Department of Veterans Affairs medical centers to
determine the capabilities of servicemembers (SMs)
with traumatic lower-limb loss (LLL) in the performance
of high-level mobility. The goal of the outcome
measure is to assist the clinician to determine
current function, measure change in function over
time during rehabilitation, and help predict when the
SM with LLL can return to high-level activity such
as sport. We found that the CHAMP is a safe and
reliable outcome measure of high-level mobility for
SMs with traumatic LLL.

Construct validity of Comprehensive High-Level Activity Mobility Predictor (CHAMP) for male servicemembers with traumatic lower-limb loss
Robert S. Gailey, PhD, PT, et al.
We developed a new outcome measure called
the Comprehensive High-Level Activity Mobility
Predictor (CHAMP) that assists military clinicians
in determining the capabilities of servicemembers
with traumatic lower-limb loss to perform high-level
mobility. One of the primary steps in developing the
CHAMP was to confirm that it actually measures
what it is intended to measure. We found that the
CHAMP was a valid measure of high-level mobility
in servicemembers with amputation. We also determined
that the CHAMP has the ability to discriminate
between different levels of lower-limb loss in
young, male servicemembers.

Comparison of 6-minute walk test performance between male Active Duty soldiers and servicemembers with and without traumatic lower-limb loss
Alison A. Linberg, DPT, ATC, et al.
We established reference data for a commonly
used functional outcome measure, the 6-minute walk
test, for servicemembers with and without lowerlimb
loss. These data will help clinicians and military
and nonmilitary individuals with lower-limb loss
track progression of rehabilitation and set realistic
function and mobility goals for rehabilitation.

Comparison between microprocessor-controlled
ankle/foot and conventional prosthetic feet during stair negotiation in people with unilateral transtibial amputation
Vibhor Agrawal, PhD, et al.
We compared prosthetic feet with different ranges of
motion at the ankle during stair negotiation to determine
work symmetry between the intact and prosthetic
limbs. All participants received standardized
functional training specific for each foot. We found
that the microprocessor-controlled prosthetic foot,
with active dorsiflexion, resulted in greater work
symmetry than conventional prosthetic feet during
stair ascent. While descending stairs, subjects employed
a similar movement strategy with all feet.
Prosthetic users who encounter stairs frequently may
benefit from a microprocessor-controlled foot.

Comparison of three agility tests with male servicemembers: Edgren Side Step Test, T-Test, and Illinois Agility Test
Michele A. Raya, PhD, PT, SCS, ATC, et al.
We established the reliability and validity of
three similar yet distinct tests that assess agility performance,
called the Edgren Side Step Test, T-Test,
and Illinois Agility Test, in young, fit Active Duty
servicemembers (SMs). We found these tests to be
reliable in that two clinicians can administer each of
these tests to the same SM and be confident that they
are scoring the performance in the same way. It was
found that all three tests assess different aspects of
agility, and together have the potential to be used as
a comprehensive assessment of high-level mobility
for sport and tactical activities.

Amputee Mobility Predictor-Bilateral: A performance-based measure of mobility for people with bilateral lower-limb loss
Michele A. Raya, PhD, PT, SCS, ATC, et al.
We identified a lack of performance-based
instruments designed for use with people with bilateral
lower-limb amputation. To address this deficiency,
we modified the Amputee Mobility Predictor (AMP)
to more accurately reflect the functional capabilities
of people with bilateral lower-limb amputation. The
modified version is called the AMP-Bilateral (AMPB).
We found that the AMP-B and the AMP have a
strong relationship with the 6-minute walk test in the
higher functioning servicemembers with bilateral
lower-limb loss. The AMP-B can assist clinicians
at the Department of Defense medical treatment
facilities and Department of Veterans Affairs medical
centers determine the capabilities of servicemembers
and veterans with traumatic bilateral lower-limb loss
in the performance of mobility-related tasks.

Factors related to high-level mobility in male servicemembers with traumatic lower-limb loss
Ignacio A. Gaunaurd, PhD, MSPT, et al.
Currently, many servicemembers (SMs) who experience
traumatic lower-limb loss seek to return to
high-level mobility activities such as sport. Yet, it has
been reported that less than a quarter of them actually
return to high-level activity. The purpose of this study
was to examine the possible relationship between
different factors that can be affected by rehabilitation,
other factors associated with lower-limb loss,
and high-level mobility, as measured by a new outcome
measure called the Comprehensive High-Level
Activity Mobility Predictor in SMs with traumatic
lower-limb loss. We found that rehabilitation-related
factors such as lower-limb strength and balance
and other factors such as the number of knee joints,
waist circumference measurement, and prosthetic
foot type were related to high-level mobility. These
results could help guide rehabilitation programs and
clinical interventions to help maximize the potential
of our SMs with traumatic lower-limb loss return to
high-level mobility activities.

Effects of 660 nm low-level laser therapy on muscle healing process after cryolesion
Natalia C. Rodrigues, PhD, et al.
Skeletal muscle injuries are often seen in rehabilitation
centers. Although muscle tissue can regenerate
after injury, this usually happens slowly and results in
muscle weakening, pain, and reinjury. Treatments are
needed that will speed up this process and, in doing
so, decrease rehabilitation time and return the patient
to previous functioning as quickly and thoroughly as
possible. Low-level laser therapy (LLLT) is a promising
treatment for skeletal muscle recovery, and
its effectiveness has been demonstrated over the
years. We found that LLLT at two levels positively affected rats– injured skeletal muscle, speeding up
the muscle-regeneration process.

OtoID: New extended frequency, portable
audiometer for ototoxicity monitoring
Marilyn F. Dille, PhD, et al.
A new portable hearing testing device, the OtoID,
was designed to monitor hearing while a Veteran is
undergoing treatment for cancer. Since many Veterans
enter treatment with hearing loss, minimizing
any additional treatment-related hearing loss is very
important. The OtoID device allows a Veteran to test
himself using an automated testing mode or be tested
by an audiologist using a manual testing mode. We
tested 50 subjects in a sound booth and on a hospital
ward for 3 days and found that the OtoID provided
equivalent results regardless of the test environment,
subject age, or hearing ability.

Influence of prior activity on residual limb volume and shape measured using plaster casting: Results from individuals with transtibial limb loss
Joan E. Sanders, PhD, et al.
The purpose of this research was to determine
whether prior activity affected the shape of a plaster
cast taken of a residual limb. Plaster casts were taken
twice a day on subjects with transtibial amputation
using standard clinical casting procedures. Results
showed that prior activity influenced residual-limb
cast shape. Patients with amputation and practitioners
should be mindful of the patient's activities before
casting for a new prosthetic socket.

Evaluation of scooters using ANSI/RESNA standards
Ana E. Souza, PhD, PT, et al.
Scooters are popular mobility devices. To date,
only one study has looked at how stable the scooters
are according to standard tests. Our study looked at
12 three-wheeled scooters, and most of them had different
results on each standard test. Smaller scooters
were more unstable and tended to fall to the side easily
during sharp turns. Half the scooters did not survive
the time equivalent to 5 years of use as required
by the standards. Our results indicate that those commercially
available scooters may not meet the standard
requirements and suggest revision of framework
requirements, such as using a test dummy according
to the device weight capacity and adding tests to
evaluate the scooter's tiller to ensure that these devices
are safe and durable.

Prolonged electrical stimulation-induced gluteal and hamstring muscle activation and sitting pressure in spinal cord injury: Effect of duty cycle
Christof A. J. Smit, MD, et al.
Pressure ulcers (PUs) are the most prevalent secondary
complications in individuals with spinal cord
injury (SCI). An active way to prevent PUs might
be muscle activation using electrical stimulation
(ES), which has been found to improve both interface
pressure distribution and intrinsic risk factors.
ES applied to the gluteal and hamstring muscles in a
custom-made garment with built-in electrodes gives
significant pressure relief of the ischial tuberosities
even after 3 h of activation in individuals with SCI.
Participants scored the usability of the ES shorts as
satisfactory, and all stated they would wear them daily
should they help prevent PUs.
