About the research
Those with osteoporosis often have weaker bones and this leads to higher chances of fractures. Therefore, the investigators want to evaluate the feasibility and safety of group exercise classes specifically designed for individuals with osteoporosis who had an osteoporotic fracture. By focusing on this high-risk population, the investigators want to see whether such exercise interventions can be an option for improving bone health, reducing the risk of future fractures, and enhancing physical function without compromising safety.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Diagnosed with osteoporosis.
- History of low trauma fracture within the past year
- Cleared for physical activity using the get active questionnaire, 100 bpm resting heart rate or less, 160 mm Hg diastolic blood pressure or less
- Able to understand and provide informed consent.
- Residing within the study's geographic area (e.g., London, Ontario).
Exclusion Criteria:
- Individuals who do not understand the English language
- Medical conditions contraindicating participation in exercise (e.g., uncontrolled cardiovascular disease, severe respiratory illness).
- Cognitive impairments that prevent informed consent or participation.
- Recent major surgeries or medical events limiting physical activity.
- Participation in conflicting clinical trials or rehabilitation programs.
- Residents outside the designated study area.
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Experimental Arm for Feasibility study
Feasibility Intervention
Other: Exercise Program
Exercise Program OTHER
Participants complete a 12-week, twice weekly, whole body group exercise program. Participants will also complete qualitative interviews and DXA bone scans.
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Recruitment Feasibility
Time frame: Assessed over 12 months
Recruitment feasibility will be assessed by the number of participants enrolled in the study over a 12-month recruitment period. The target recruitment goal is 100 participants.
Retention Feasibility
Time frame: Assessed at 12 weeks
Retention feasibility will be assessed as the percentage of enrolled participants who complete the 12-week reassessment. The predefined retention target is 60%. Percentages range from 0% to 100%, with higher percentages indicating better retention feasibility.
Exercise Class Adherence
Time frame: Assessed over the 12-week intervention period
Exercise adherence will be assessed using class attendance records. Adherence will be calculated as the percentage of scheduled exercise sessions attended by each participant. The predefined adherence target is 80%. Percentages range from 0% to 100%, with higher percentages indicating better adherence.
Secondary measures
Program Acceptability
Time frame: Assessed at 12 weeks
Program acceptability will be assessed using participant exit interviews conducted at the completion of the intervention. Acceptability will be calculated as the percentage of participants who report a positive response regarding satisfaction with the program. The predefined acceptability target is 80%. Percentages range from 0% to 100%, with higher percentages indicating greater program acceptability.
Intervention Safety
Time frame: Assessed throughout the 12-week intervention period
Intervention safety will be assessed by recording the number and type of adverse events attributable to the intervention, including falls, musculoskeletal pain, prolonged muscle soreness, dizziness, fainting, shortness of breath, and other participant-reported medical concerns. Lower numbers indicate better intervention safety.
Other measures
Change in Bone Quality
Time frame: Baseline and 12 weeks
Bone quality will be assessed using dual-energy X-ray absorptiometry (DXA), including Trabecular Bone Score assessment of bone microarchitecture. Higher bone mineral density and Trabecular Bone Score values indicate better bone health and bone microarchitecture.
Change in health care utilization
Time frame: Assessed over the 6-month period following completion of the exercise program
Health care utilization will be assessed using Institute for Clinical Evaluative Sciences (ICES) health administrative records. Measures of health care utilization may include health care visits, hospitalizations, and fracture-related health service use following participation in the exercise program. Lower health care utilization and fewer fracture-related events may indicate improved health outcomes.
Change in Physical Function
Time frame: Baseline, 6 weeks, and 12 weeks
Physical function will be assessed using the Short Physical Performance Battery. Scores range from 0 to 12, with higher scores indicating better lower extremity physical function.
Change in Functional Exercise Capacity
Time frame: Baseline, 6 weeks, and 12 weeks
Functional exercise capacity will be assessed using the 6-Minute Walk Test. Distance will be measured in meters, with greater distances indicating better functional exercise capacity.
Change in Mobility
Time frame: Baseline, 6 weeks, and 12 weeks
Mobility will be assessed using the Timed Up and Go Test. Time will be measured in seconds, with lower times indicating better mobility and lower fall risk.
Change in Single Leg Balance
Time frame: Baseline, 6 weeks, and 12 weeks
Static balance will be assessed using the Single Leg Balance Test. Time will be measured in seconds, with longer durations indicating better balance performance.
Change in Osteoporosis-Specific Quality of Life
Time frame: Baseline, 6 weeks, 12 weeks, and 6 months
Quality of life will be assessed using the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO). Scores range from 0 to 100, with lower scores indicating better quality of life.
Change in Overall Health-Related Quality of Life
Time frame: Baseline, 6 weeks, 12 weeks, and 6 months
Health-related quality of life will be assessed using the EuroQol 5 Dimension (EQ-5D). Scores range from less than 0 to 1, with higher scores indicating better health-related quality of life.
Change in Physical Activity
Time frame: Baseline, 6 weeks, 12 weeks, and 6 months
Physical activity participation will be assessed using the Physical Activity Scale for the Elderly. Scores range from 0 to over 400, with higher scores indicating greater physical activity participation.
Change in Grip Strength
Time frame: Baseline, 6 weeks, and 12 weeks
Grip strength will be assessed using hand dynamometry. Grip strength will be measured in kilograms, with higher values indicating greater grip strength and upper extremity muscle function.
