Eksperimentel: Structured Resistance Training Program
Participants with surgically managed diaphyseal femur or tibia fractures who participate in a 12-week structured, supervised resistance training and activity program initiated approximately 12 weeks after surgery, in addition to usual postoperative care.
|
A 12-week structured exercise intervention delivered at a community fitness facility by trained study personnel.
The program includes 24 supervised small-group resistance training sessions (two per week, 50-75 minutes each), 12 weekly one-to-one coaching sessions (~30 minutes each), and a brief daily home activity program (10-15 minutes per day).
The exercise program follows a criteria-based, progressive strength and conditioning framework including mobility, neuromuscular control, strength, power, and fatigue-resistance components.
All sessions are supervised by study personnel, and no gym staff are involved in intervention delivery or data collection.
|
|
Ingen indgriben: Usual Care Control
Participants with surgically managed diaphyseal femur or tibia fractures who receive usual postoperative care without participation in the structured supervised exercise or coaching program.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Recruitment rate (participants enrolled per month)
Tidsramme: Up to 6 months
|
Feasibility will be assessed by the number of participants enrolled per month during the recruitment period.
|
Up to 6 months
|
|
Adherence to supervised resistance training program (% of prescribed sessions completed)
Tidsramme: Up to 6 months
|
Adherence will be calculated as the proportion of completed training sessions out of the total prescribed sessions.
|
Up to 6 months
|
|
Participant retention rate (% completing follow up assessments)
Tidsramme: Up to 6 months
|
Retention will be defined as the proportion of participants who complete all scheduled follow-up assessments.

Tidsramme |
|---|---|---|
|
Patient Specific Functional Scale Score
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Patient-reported functional status assessed using the Patient-Specific Functional Scale (PSFS), in which participants rate difficulty performing self-selected activities on a 0-10 scale.
Higher scores indicate better function.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Health-related quality of life measured using SF-12
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Health-related quality of life assessed using the 12-Item Short Form Health Survey (SF-12).
Higher scores indicating better health status.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Pain intensity measured using Numeric Pain Rating Scale (0-10)
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Pain intensity measured using a numeric rating scale ranging from 0 (no pain) to 10 (worst possible pain).
|
12, 18, 24, and 52 weeks post-surgery
|
|
Short Musculoskeletal Functional Assessment (SMFA) score
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Self-reported musculoskeletal function assessed using the Short Musculoskeletal Functional Assessment (SMFA) questionnaire.
Scores are reported according to standardized scoring procedures, with higher scores indicating greater functional limitation.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Functional Independence Test for Lower Extremity Injuries (FIX-IT) score
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Lower extremity functional performance assessed using the Functional Independence Test for Lower Extremity Injuries (FIX-IT), a performance-based measure of functional mobility following lower extremity injury.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Lateral movement performance measured using Edgren Sidestep Test (seconds)
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Lateral movement and agility assessed using the Edgren Sidestep Test.
Performance is recorded as time to completion in seconds.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Body weight (kilograms)
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Body weight measured in kilograms using a calibrated scale.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Body mass index (BMI, kg/m²)
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Body mass index calculated as weight in kilograms divided by height in meters squared.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Thigh circumference measured in centimeters
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Thigh circumference measured in centimeters using a standardized tape measure to assess lower extremity muscle girth.
|
12, 18, 24, and 52 weeks post-surgery
|
|
Lower extremity muscle strength measured by exercise research team (force output)
Tidsramme: 12, 18, 24, and 52 weeks post-surgery
|
Lower extremity muscle strength assessed using standardized strength testing procedures performed by the exercise research team.
Strength outcomes will be reported as force output using consistent measurement methods.
|
12, 18, 24, and 52 weeks post-surgery
