Clinical Trial Summary
Osteoporosis is a common condition found in postmenopausal women. Osteoporosis increases the
risk of fractures: especially hip and vertebral fractures. These fractures increase the risk
of morbidity and mortality. Falls and movements that incorporate trunk flexion or rotation
can increase the risk of fractures in women with osteoporosis. Weight-bearing exercise and
posture training are important complementary therapies to help decrease the risk of fractures
and improve the function of individuals with osteoporosis. Often in Rheumatology clinic,
patient's will be given handouts concerning bone building exercises and tips on holding safe
postures with activities to complete, with little follow-up of their progress or evaluation
of their technique. In this study, we will compare a video-based exercise intervention with
printed handout group to a handout only group and will evaluate the effectiveness of these
two different modalities using physical activity measures and overall outcomes of strength
and posture.
Description:
Osteoporosis is a common condition found in postmenopausal women. Osteoporosis increases the
risk of fractures: especially hip and vertebral fractures. These fractures increase the risk
of morbidity and mortality. Falls and movements that incorporate trunk flexion or rotation
can increase the risk of fractures in women with osteoporosis. Weight-bearing exercise and
posture training are important adjunctive therapies to help decrease the risk of fractures
and improve the function of individuals with osteoporosis. Often in Rheumatology and
osteoporosis clinics, participant's will be given handouts concerning posture and exercise to
complete, with little follow-up of their progress or evaluation of their technique. In this
study, investigators will determine if the addition a video-based exercise intervention with
handouts and limited physical therapist instruction and monitoring help this population
increase adoption of a regular exercise program designed to improve lower extremity strength
and dynamic posture.
The purpose of this study is to determine if the addition of computer-based video
instructions with handouts and limited physical therapist (PT) instruction helps adoption and
performance of an intervention designed to improve strength, dynamic posture, and balance in
individuals with osteoporosis (OP). Investigators will perform all measurements and
interventions via web-based and telecommunication technology. Twenty-four participants will
be recruited for this feasibility study using flyers posted in the Rheumatology and
Osteoporosis clinics at the University of Alabama at Birmingham (UAB). The investigators, who
help staff these clinics, will also alert other clinic physicians of this study via flyers
designed for these health care professionals to help recruit study participants. The
participants will consent to participate in this study. The UAB Institutional Review Board
will approve this study.
After consenting, a physical therapist (PT), blind to group assignment, will perform outcome
measurements. Outcome measurements will be assessed at baseline and within a week after the
12-week intervention is completed. Measurements include five-time sit-to-stand-to sit
(5xSTS), 4-stage balance test, and a dynamic posture test. Participants will also complete a
questionnaire that examines demographics, medical history, exercise and fall perceptions, and
functional activity performance. The pre- and post-intervention questionnaires will be
similar except the post-intervention questionnaire will not include demographic, medical
history questions, and perceived readiness to exercise item. SurveyMonkey will be used to
deliver and collect all questionnaire data. The post-intervention questionnaire will contain
items assessing intervention satisfaction.
Prior to enrolling participants, investigators will develop a script and checklist for the PT
performing the measurements to increase consistency of outcome measurement. The PT will also
practice these measurements using Zoom and intra-rater reliability will be determined.
Intra-rater reliability will also be assessed from the data collected. Finally, investigators
will perform quality control by reviewing recordings of the measurement sessions.
After baseline measurements, participants will be randomly assigned to one of two groups: one
group will receive handouts that provide program instructions with PT coaching (HO) or a
group who receives the same instructional delivery plus links to web-based videos instructing
all elements of the program intervention (HO+). Participants will be asked to perform
moderate level exercise/posture activity 5 sessions/week for 35 to 40 minutes per day
(duration of activity/session by the end of the intervention). By email, the HO+ group
participants will receive handouts with links to access the safe exercise posture
instruction, posture warm-up, balance exercise resistance exercise and marching. The HO group
will also receive an email that with the same attachments minus the video links. In both
groups, the first intervention instruction email will instruct the participants to not start
the program until the intervention PT (not the same PT who performs the measurements) guides
them through the program via a Zoom videoconference. In week two, the intervention PT will
finish the initial instructions in another 60-minute session. The PT will meet with
participants during the third week of the intervention for a 15-minute meeting and will
continue to meet with participants for 15-minutes every two weeks thereafter via Zoom. During
these 15-minute sessions, the intervention PT will help individuals progress exercises,
monitor symptoms, answer questions, and make performance recommendations. All participants
will be instructed to track their posture and exercise activity by using a monitoring log
provided by the research group. These logs will be shared with the investigators.
Both groups will perform marching in place five times a week. Participants will be instructed
to slowly progress to a goal of performing 30 minutes of marching in place per session. They
will be instructed to lift their knees to a height that is between their waist and knee when
marching. Participants will start performing at 5 minutes of marching twice a day. Every two
weeks they will progress the goal of marching time by 5 minutes. They will march two times
per day until they reach 20 minutes. At this time, they will march one time per day. They
will be instructed to march between a rating of 10 -14 on the 20-point Borg scale for rate of
perceived exertion. The intervention PT will help participants in both groups progress safely
when she teleconferences with each participant every two weeks.
Posture training will be performed daily. The participants will be taught how to hold good
posture with activity over two 60-minute sessions by the intervention PT. In the first visit,
the intervention PT will discuss holding dynamic posture basics, finding and holding good
posture in sitting and sit to stand. In the next visit, she will teach them how to progress
to standing activities while holding good posture. The PT will instruct the participant to
use the posture activities as a warm-up on all days of exercise. She will also encourage
participants to incorporate these skills in daily activities.
The intervention PT will use scripts and checklists developed prior to participant enrollment
to ensure consistency of instruction between participants. The intervention PT will practice
instructing participants prior to participant enrollment via Zoom with other investigators.
These sessions will be taped so that they can be reviewed and scripts and checklists refined.
Demographic, satisfaction data, perception items and scales will be analyzed using
appropriate descriptive statistics. Descriptive statistics, such as means and standard
deviations, will also be used to describe data from 5xSTS and balance tests. These tests will
also be analyzed using Cohen d to determine effect size. To determine within and between
group differences over time, mixed-factor ANOVAs will be used. Finally, a Wilcoxon-Signed
Rank test will be used to determine differences between the groups for the dynamic posture
test.
