It is also possible that PRT alone is not a robust intervention for balance control .
This is the first systematic synthesis of the literature to examine the effectiveness of PRT alone on balance performance in older adults .
The limited evidence presented in currently published data has not consistently shown that the use of PRT in isolation improves balance in this population .
The serious health , social and economic consequences of falls are well documented .
Lower extremity muscle weakness and power as well as balance impairment are major independent intrinsic contributors to falls and amenable to intervention .
Progressive resistance training ( PRT ) is widely accepted as an appropriate modality for treating sarcopenia and has been reported to improve balance .
However , other studies affirm no significant effect of PRT on balance .
To date , there is no clear , definitive statement or synthesis of studies that has examined the effect of PRT on balance .
Therefore , our objective was to systematic ally review the literature to probe the merit of PRT as a single intervention on balance performance in older adults .
The effects of physical therapists' guidance on improvement in a strength-training program for the frail elderly.
Elderly participants experiencing difficulty in chair rising and with a maximum knee-extensor torque below 87.5 N . m were r and omized  to different versions of a strength-training program for the knee-extensors : to a high-guidance group ( HG ; two group sessions supervised by a physical therapist and one unsupervised home session per week , n = 17 ) , a medium-guidance group ( MG ; one supervised group session and two unsupervised home sessions per week , n = 16 ) , or a control group ( C ; no exercise , n = 16 ) . Maximal isometric knee strength increased more in HG than in C ( p = .03 ) and with increasing guidance ( p = .03 ) . The effect was mainly the result of participants with low initial strength . Walking speed increased more for HG than for C ( p = .02 ) and than for MG ( p = .06 ) . No statistically significant improvements were seen on other functional tests . In summary , the study shows a trend toward better results with more supervision , but more and larger studies are needed to confirm this
