Post-osteoporotic Fracture Exercise Program

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 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 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.

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 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.

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.

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.

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.

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.

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.

Static balance will be assessed using the Single Leg Balance Test. Time will be measured in seconds, with longer durations indicating better balance performance.

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.

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.

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.

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.
