Conclusions This review provides evidence that RT has a moderate positive effect on self-reported disability/function  in old people with or at risk for disability .
The effects are strongly associated with effects on objective measures of lower body functional capacity
Background Self-reported disability has a strong negative impact on older people ’s  quality of life and is often associated with the need for assistance and health care services .
Resistance training ( RT ) has been repeatedly shown to improve muscle function ( e.g. strength ) and functional capacity ( e.g. gait speed , chair-rise ) in older adults with functional limitations .
Nevertheless , it is unclear whether such objective ly assessed improvements translate into a reduction in self-reported disability .
Objectives To assess : i ) whether and to what extent RT interventions have an effect on self-reported disability in older adults ( ≥65 years ) with functional limitations or disability ; and ii ) whether the effects on self-reported disability are associated with changes in objective measures of muscle strength and functional capacity across studies .
A systematic review of workplace interventions to prevent low back pain.
A systematic review of r and omised controlled trials was undertaken to evaluate the effectiveness of  workplace interventions  to prevent low back pain .  Potential trials were located by a computerised search supplemented with citation tracking . The method ological quality of the trials was assessed on 11 criteria and the level of evidence for each intervention was determined , based upon the amount , consistency and quality of evidence from the trials . The review located 13 trials that were generally of moderate quality . The trials suggest that work place exercise is effective , braces and education are ineffective , and workplace modification plus education is of unknown value in preventing low back pain
