Feasibility of progressive strength training shortly after hip fracture surgery

Figure 1 The progressive strength training included unilateral (fractured limb) knee-extension (A) and bilateral leg presses (B).

Figure 2 Feasibility of the programme. A: Absolute weight load over 12 fractured knee-extension strength-training sessions; B: Absolute weight load over 12 bilateral leg press strength-training sessions. ^bP < 0.001 vs RM-F. RM: Repetition maximum; F: First session; L: Last session.

Figure 3 Hip pain. A: Hip pain over 12 fractured knee-extension strength-training sessions; B: Hip pain over 12 bilateral leg press sessions; C: Hip pain at rest and at the time of baseline functional testing or at the first strength-training session; D: Hip pain at rest and at the last testing or training session. RM: Repetition maximum; F: First session; L: Last session.

Figure 4 Follow up. A: Improvements in function and knee-extension strength after 6 wk of training, ^bP < 0.001 vs Intention to treat analysis (n = 39); B: Correlations between knee-extension strength and function after 6 wk of training, ^aP < 0.05 vs Knee-extension strength, non-fractured. FKES: Fractured knee extension strength; NFKES: Non-fractured knee extension strength; 10mWT: 10-m walk test; 6MWT: 6-min walk test; SF-36P: Short form-36 physical; NMS: New mobility score.
