Main Outcome Measure(s): During each session, the current amplitude,
ankle weight and repetitions were recorded. The average of two consec-
utive sessions was used to represent that data of every week. Repeated
measure analysis of variances (ANOVA) was used to analyze data from
weeks 1, 4, 8, 12 and 16.
Results: Lifted weight significantly (P<0.0001) increased over the 16
week training period for the right (19.66.5 lbs.) and the left (206.1 lbs.)
legs. Amplitude of the current did not change significantly over the course
of 16 week period. The amplitude of the current was significantly greater
in the third and fourth sets compared to the first and second sets. Ampli-
tude of the current was significantly lower in the left leg compared to the
right leg in weeks 1, 4, 8, 12 and 16 of the training. The total number of
repetitions was not different across the 16 weeks.
Conclusions: Despite a progressive increase in weights, the amplitude of
the current required to perform leg extension did not change over the 16
weeks of RT. A shin weight on average of 20 lbs. or less than 26 lbs.
appears to be a safe strategy to perform dynamic leg extension in chronic
individuals with SCI. There is a clear discrepancy in the amplitude of the
current between the right and left legs; which requires further studies.

Walking Individuals Post-Stroke with Pushing
Behaviors Overground and on A Treadmill During
Inpatient Rehabilitation: A Case Series

T. George Hornby
Research Objectives: To ambulate individuals post stroke with pushing
behaviors overground and on a treadmill to assess feasibility and impact on
pushing behaviors.
Design: Case series.
Setting: Inpatient rehabilitation.
Participants: Convenience sample of six individuals post-stroke demon-
strating pushing behaviors (scoring >0 in all 3 categories of the Scale for
Contraversive Pushing).
Interventions: Thirty minute sessions of the following- sitting in a
wheelchair as a control, ambulation overground, and ambulation on a
treadmill with body weight support as needed. Rater was blinded to
treatment session and session order was randomized. The treating physical
therapist could use clinical judgment for appropriate assistive devices,
cuing, use of mirror, and body weight support while maximizing repeti-
tions of stepping during session.
Main Outcome Measure(s): Burke Lateropulsion Scale(BLS), time and
distance ambulated.
Results: All individuals were able to ambulate on both treadmill and
overground with 1-3 person assist although technique used, distance (150’-
792’ treadmill and 104-432’ overground), and active walking time
(9-23minutes treadmill and 8-30minutes overground) ambulated varied.
Response of pushing behaviors to walking and sitting varied per BLS. All
individuals pushed less during 2nd therapy session of ambulation per
therapist report, regardless of order of treatment, except Pusher4 with no
change and slight increase in frequency noted in Pusher1. There is no
evidence that an increase in pushing behaviors during treatment on day 1
lead to an increase in pushing behaviors the following days.
Conclusions: Though most current treatments for individuals with
pushing behaviors focus on finding midline prior to performing higher
level skills, physical therapists can safely ambulate individuals post
stroke with varying levels of pushing behaviors. Pushing behaviors
during and after ambulation varies between individuals. More studies
need to be performed to identify factors that may impact push-
ing behaviors.

Research Objectives: To compare the outcomes of a conventional, exer-
cise-based rehabilitation intervention for chronic low back pain (cLBP)
with the outcomes achieved by combining a conventional intervention with
adjunct therapy delivered using an interactive gaming system for home-
based therapy.
Design: Randomised controlled trial.
Setting: Rehabilitation hospital (outpatient).
Participants: Six adults 31.8 3.9 years old diagnosed with non-specific
cLBP and pain intensity >3 (on a visual analog scale - VAS).
Interventions: Conventional physical therapy for both groups for 8 weeks.
The Usual Care group (UCG, nZ3) re ceived presc ription of additional regular
home-based exercises. The Game Therapy group (GTG, nZ3) performed
instead home exercises using the Valedo interactive gaming system.
Main Outcome Measure(s): Pain intensity (Visual Numeric Scale - VNS
0-10), number of days with pain and severity of bothersome pain (VAS
0-10) over the last week; Owestry questionnaire; and exercise adherence.
Results: Both groups showed general improvements in response to treat-
ment. The GTG showed greater improvement in pain intensity (-1.7 points)
than the UCG (+0.3 points). It also showed a greater change in the
Oswestry score (4.3 points) than the UCG (0.6 points). However, the UCG
showed a greater change in number of days with pain over the last week
(-3.3 days) than the GTG (+0.3 days). It also showed a greater change in
the severity of bothersome pain over the last week (-1.3 on a VAS 0-10)
than the GTG (+0.33). Exercise adherence was higher in the UCG (57%)
than in the GTG (49%).
Conclusions: The study has so far shown the feasibility of utilizing an
interactive gaming system in the treatment of patients with cLBP. Future
results of this clinical trial (as we continue to recruit subjects) will
contribute to determine the effectiveness of this treatment option.

In Hospital Statin Use is Associated with Fewer
Days to Follow Commands Only among Men with
Traumatic Brain Injury
Raj Kumar (University of Pittsburgh), Emma Steinmetz,
Shannon B. Juengst, Amy K. Wagner
Research Objectives: 1) Examine the effect of statin use during inpatient
hospitalization on hospital-based and 1 year outcomes among adults over
50 after moderate-severe TBI, 2) Assess whether there were significant
differences in the effects of statin use by sex.
Design: Observational study design; Retrospective chart review for statin
medication use; Prospective collection of hospital-based variables and
1-year outcomes (Pittsburgh TBI Model Systems).
Setting: Level I Trauma Center and Brain Injury Rehabilitation Unit at the
University of Pittsburgh Medical Center.
Participants: Adults (nZ206) over 50 with moderate-severe TBI enrolled
into the Pittsburgh TBI Model Systems.
Interventions: Statin (simvastatin, lovastatin, pravastin, atorvastatin,
rosuvastatin, pitavastatin, fluvastin, or gemfibrozol) use gathered from
review of medications in the electronic medical records.
Main Outcome Measure(s): Days to follow commands, days of post-
traumatic amnesia, length of acute and rehabilitation hospital stay, 1 year
mortality, and rehospitalization in the 1st year.
