Purpose
Intensified acute in-hospital physiotherapy (IP) after hip fracture (HF) may enhance patient’s ability to regain basic mobility at discharge. The primary objective was to assess the feasibility of IP. Secondary to estimate the effect of IP on regained basic mobility at discharge.

Materials and methods
In a pragmatic, randomized, unblinded feasibility trial, 60 patients (mean age 79 years, 41 women) with HF and an independent pre-fracture basic mobility level were randomized (2:1) to IP with two daily sessions on weekdays focusing on functional training and weight-bearing activities (n = 40) versus usual care (UC) physiotherapy once daily (n = 20). Feasibility outcomes included physiotherapy completion rates, reasons for non-successful completion, and adverse events. The primary effect outcome was recovery of basic mobility (Cumulated Ambulation Score (CAS)).

Results
Eighty-two percent of the sessions in the IP group were successfully- or partially completed versus 94% of the sessions in the UC group. No adverse events occurred. The main reason for not completing physiotherapy was fatigue. At discharge (median 7 days), 50% in the IP group had regained their pre-fracture basic mobility level (CAS = 6) versus 16% in the UC group; odds ratio = 5.33, 95%CI [1.3;21.5].

Conclusions
IP seems feasible for patients after HF surgery, and it may enhance recovery. Fatigue was the primary obstacle to completing IP.

Implications for rehabilitation
Two daily physiotherapy sessions focusing on functional training and weight-bearing activities are feasible for patients after isolated hip fracture surgery, including subtrochanteric fracture, and may enhance recovery of basic mobility at discharge.

During hospitalization, patient participation in intensified physiotherapy is mainly restricted by fatigue.

Systematic assessment and management of fatigue may improve the completion of physiotherapy and recovery of basic mobility.
