Feasibility of Structured Resistance Training After Lower Extremity Fracture

1 juni 2026 bijgewerkt door: London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's

Feasibility and Impact of a Structured, Supervised Exercise Program Following Lower Extremity Fracture: A Pilot Controlled Study

Adults recovering from surgically managed diaphyseal femur or tibia fractures often experience persistent weakness, pain, and functional limitations despite successful fracture healing. This prospective, non-randomized pilot study evaluates the feasibility and acceptability of a structured, supervised resistance training program initiated approximately 12 weeks after surgery, compared with usual postoperative care alone. The study will assess recruitment, adherence, retention, and protocol fidelity, and will collect exploratory patient-reported and physical function outcomes to inform the design of a future randomized controlled trial.

Gedetailleerde beschrijving

This is a prospective, non-randomized, controlled pilot feasibility study enrolling adults aged 20 to 65 years with isolated diaphyseal femur or tibia fractures treated surgically with locked intramedullary nail fixation. Participants will be recruited from routine postoperative fracture clinic visits and enrolled approximately 10 to 14 weeks after injury, once fracture healing has progressed sufficiently to allow full weight bearing and independent participation in supervised exercise.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: 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.
Gedragsmatig: Structured Supervised Resistance Training and Coaching Program
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.
Geen tussenkomst: 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.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Recruitment rate (participants enrolled per month)
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: Up to 6 months
Retention will be defined as the proportion of participants who complete all scheduled follow-up assessments.
Up to 6 months

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Patient Specific Functional Scale Score
Tijdsspanne: 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
Tijdsspanne: 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)
Tijdsspanne: 12, 18, 24, and 52 weeks post-surgery
