Objective To identify Rehabilitation Indices associated with a minimal trauma fracture (MTF) within 12 months poststroke. Methods Retrospective case-control study. Stroke survivors with MTF were matched 5:1 with stroke survivors without MTF. Logistic regression determined whether Rehabilitation Indices, such as Physiotherapy Ambulation score (PhysioAmb), were associated with a MTF within 12 months poststroke. Results Forty-three stroke survivors (mean age: 79.8; 55.81% female) experienced a MTF (median time to MTF of 1.79 years [IQR 0.70, 4.48]). Those with a MTF within 12 months had lower PhysioAmb (4.53 vs 8.29) and Berg Balance Scale (BBS; 12.25 vs 40.57) scores on admission, lower BBS score on discharge (30.33 vs 49.29) and a greater change in PhysioAmb (+5.67 vs +3.24) and BBS scores (+21.50 vs +8.71) after rehabilitation, all P MTF within 12 months by 18%. Conclusion Rehabilitation Indices are associated with a MTF within 12 months poststroke.
