Functioning measure | Annualized rate of change | |
---|---|---|
absolute change | as % of baseline | |
Grip strength, dominant hand (kg) | −0.20 kg/yr | 0.8 % less/yr |
Forward reach (cm) | −0.16 cm/yr | 0.4 % less/yr |
2-lb lift (sec) | +0.04 sec/yr | 2.9 % longer/yr |
Sit-to-stand (sec) | 0.003 sec/yr | 0.3 % longer/yr |
Timed stair climb (sec) | +0.29 sec/yr | 1.9 % longer/yr |
Leg strength (Nm) | −2.2 Nm/yr | 2.6 % less/yr |
40-foot timed walk (sec) | +0.11 sec/yr | 1.4 % longer/yr |
Velocity (cm/sec) | −0.69 cm/sec/yr | 0.4 % slower/yr |
Physical functioning perception (SF-36 physical functioning score) | −0.43 points/yr | 0.5% less/yr |
Changes with time are significantly different than zero (p<0.05) except sit-to-stand, velocity, and the SF-36 physical functioning score.
