    Input: Background Fatigue or lack of interest can reduce the feasibility of intensive physical exercise in nursing home residents .  Low-volume exercise interventions with similar training effects might be an alternative . The aim of this r and omised controlled trial was to investigate the feasibility of Whole Body Vibration ( WBV ) in institutionalised elderly , and its impact on functional capacity and muscle performance . Methods Twenty-four nursing home residents ( 15 female , 9 male ; mean age 77.5 ± 11.0 years ) were r and omised ( stratification for age , gender and ADL-category ) to 6 weeks static WBV exercise ( WBV+ , N = 13 ) or control ( only static exercise ; N = 11 ) . Outcome measures were exercise compliance , timed up- and -go , Tinetti-test , back scratch , chair sit- and -reach , h and grip strength and linear isokinetic leg extension . Results At baseline , WBV+ and control groups were similar for all outcome variables . Twenty-one participants completed the program and attended respectively 96 % and 86 % of the exercise sessions for the WBV+ and control groups . Training-induced changes in timed up- and -go and Tinetti-test were better for WBV+ compared to control ( p = 0.029 for timed up- and -go , p = 0.001 and p = 0.002 for Tinetti body balance and total score respectively ) . In an alternative analysis ( Worst Rank Score & Last Observation Carried Forward ) the differences in change remained significant on the Tinetti body balance and total score . No other significant differences in change between both groups were observed . Conclusion In nursing home residents with limited functional dependency , six weeks static WBV exercise is feasible , and is beneficial for balance and mobility . The supplementary benefit of WBV on muscle performance compared to classic exercise remains to be explored further OBJECTIVE To use two different exercise programs over a 2-year period to reduce falls and their sequelae among residents of two long-term care facilities . DESIGN R and omized , controlled trial . SETTING The study took place at two long-term care facilities with services ranging from independent living to skilled nursing . PARTICIPANTS One hundred and ten participants whose average age was 84 and who were capable of ambulating with or without assistive devices and could follow simple directions . INTERVENTION Participants were r and omized to one of two exercise groups ( resistance/endurance plus basic enhanced programming or tai chi plus basic enhanced programming ) or to a control group ( basic enhanced programming only ) . Exercise classes were held three times per week throughout the study . MEASUREMENTS Participants were evaluated for cognitive and physical functioning at baseline and 6 , 12 , and 24 months . Falls were determined from incident reports filed by the nursing staffs at the facilities . RESULTS Time to first fall , time to death , number of days hospitalized , and incidence of falls did not differ among the treatment and control groups ( P>.05 ) . Among all participants , those who fell had significantly lower baseline Folstein Mini-Mental State Examination and instrumental activities of daily living scores and experienced significantly greater declines in these measures over the 2-year program . CONCLUSION There were no significant differences in falls among the two exercise groups and the control group . Lack of treatment differences and low adherence rates suggest that residents of long-term care facilities may require individualized exercise interventions that can be adapted to their changing needs This paper describes a quasi-experimental study of a musical exercise intervention to improve the physical , cognitive , behavioral status and life satisfaction of older residents in a long-term care facility in the United Kingdom . Twenty long-term care residents from three different units ( n=60 ) were recruited and assigned to one of three groups : a control ( C ) group ( no intervention ) , an occupational therapy ( OT ) group ( comparison group ) and a music exercise group ( intervention group ) . Assessment s of physical and cognitive status were made pre-intervention and repeated at the end of the 10-week exercise program and again 10 weeks after the completion of the program . The results show that both OT and exercise participation is associated with improvement in physical and cognitive function . However , the exercise group showed significant improvement in more areas than the OT group . The functional benefits from OT and exercise were not sustainable after these activities ceased and showed significant decline 10 weeks after the end of the programs OBJECTIVES To establish the effectiveness of a fall-prevention program in reducing falls and injurious falls in older residential care residents . DESIGN Cluster , r and omized , controlled trial . SETTING Fourteen r and omly selected residential care homes in Auckl and , New Zeal and . PARTICIPANTS All older residents ( n=628 , 95 % participation rate ) . INTERVENTION Residential care staff , using existing re sources , implemented systematic individualized fall-risk management for all residents using a fall-risk assessment tool , high-risk logo , and strategies to address identified risks . MEASUREMENTS Number of residents sustaining a fall , falls , and injurious-falls incidence rates . RESULTS During 12 months of follow-up , 103 ( 43 % ) residents in the control group and 173 ( 56 % ) residents in the intervention group fell ( P<.018 ) . There was a significantly higher incidence rate of falls in intervention homes than in control homes ( incident rate ratio=1.34 , 95 % confidence interval=1.06 - 1.72 ) during the intervention period after adjusting for dependency level ( type of home ) , baseline fall rate , and clustering . There was no difference in the injurious fall incidence rate or incidence of serious injuries . CONCLUSION This fall-prevention intervention did not reduce falls or injury from falls . Low-intensity intervention may be worse than usual care OBJECTIVE to determine the effect of risk factor modification and balance exercise on falls rates in residential care homes . DESIGN cluster r and omised controlled trial . PARTICIPANTS 196 residents ( aged 60 years or over ) in 20 residential care homes were enrolled ( 38 % response rate ) . Homes were r and omly allocated to intervention and control arms . A total of 102 residents were consigned to the intervention arm and 94 to the control arm . INTERVENTION a multifactorial falls prevention programme including 3 months gait and balance training , medication review , podiatry and optometry . MAIN OUTCOME MEASURES number of falls/recurrent falls per person , number of medications per person , and change in Tinetti gait and balance measure . RESULTS in the intervention group there was a mean of 2.2 falls per resident per year compared with 4.0 in the control group ; this failed to reach statistical significance ( P = 0.2 ) once the intra-cluster correlation ( ICC , 0.10 ) had been accounted for . Several risk factors were reduced in the intervention arm . CONCLUSIONS falls risk factor reduction is possible in residents of care homes . A modest reduction in falls rates was demonstrated but this failed to reach statistical significance Many studies have documented the effectiveness of verbally elicited imagery in the enhancement of motor skills in young , nondisabled population s. The present study examined the effects of verbally elicited imagery in the encouragement of two exercises ( i.e. , reaching up to pick apples and reaching down to pick up coins ) in elderly women . The subjects were 27 women between 62 and 96 years of age who were selected from a nursing home , a residential retirement home , and a foster care home . All of the subjects received imagery as well as control conditions , but in a counterbalanced fashion . The Wilcoxon matched-pairs signed rank tests indicated that the imagery condition elicited significantly more repetitions of the reaching-up exercise than did the control condition ( z = 2.25 , p [ one-tailed ] = .012 ) . The results in the reaching-down exercise were generally in the same direction but difficult to interpret statistically . The results are discussed in terms of other recent research investigating ways to add purpose to therapeutic exercise through occupation . Clinicians are urged to explore the advantages and disadvantages of imagery-based occupations in treatment The aims of this r and omised controlled trial were to determine if a high-intensity functional exercise program improves balance , gait ability , and lower-limb strength in older persons dependent in activities of daily living and if an intake of protein-enriched energy supplement immediately after the exercises increases the effects of the training . One hundred and ninety-one older persons dependent in activities of daily living , living in residential care facilities , and with a Mini-Mental State Examination ( MMSE ) score of ? 10 participated . They were r and omised to a high-intensity functional exercise program or a control activity , which included 29 sessions over 3 months , as well as to protein-enriched energy supplement or placebo .  Berg Balance Scale , self-paced and maximum gait speed , and one-repetition maximum in lower-limb strength were followed-up at three and six months and analysed by 2 x 2 factorial ANCOVA , using the intention-to-treat principle . At three months , the exercise group had improved significantly in self-paced gait speed compared with the control group ( mean difference 0.04 m/s , p = 0.02 ) . At six months , there were significant improvements favouring the exercise group for Berg Balance Scale ( 1.9 points , p = 0.05 ) , self-paced gait speed ( 0.05 m/s , p = 0.009 ) , and lower-limb strength ( 10.8 kg , p = 0.03 ) . No interaction effects were seen between the exercise and nutrition interventions . In conclusion , a high-intensity functional exercise program has positive long-term effects in balance , gait ability , and lower-limb strength for older persons dependent in activities of daily living . An intake of protein-enriched energy supplement immediately after the exercises does not appear to increase the effects of the training OBJECTIVES To evaluate the effectiveness of a multifaceted , nonpharmaceutical intervention on incidence of falls and fallers . DESIGN Prospect i ve , cluster-r and omized , controlled 12-month trial . SETTING Six community nursing homes in Germany . PARTICIPANTS Long-stay residents ( n = 981 ) aged 60 and older ; mean age 85 ; 79 % female . INTERVENTIONS Staff and resident education on fall prevention , advice on environmental adaptations , progressive balance and resistance training , and hip protectors . MEASUREMENTS Falls , fallers , and fractures . RESULTS The incidence density rate of falls per 1,000 resident years ( RY ) was 2,558 for the control group ( CG ) and 1,399 for the intervention group ( IG ) ( relative risk ( RR ) = 0.55 , 95 % confidence interval ( CI ) = 0.41 - 0.73 ) . Two hundred forty-seven ( 52.3 % ) fallers were detected in the CG and 188 ( 36.9 % ) in the IG ( RR = 0.75 , 95 % CI = 0.57 - 0.98 ) . The incidence density rate of frequent fallers ( > 2/year ) was 115 ( 24.4 % ) for the CG and 66 ( 13.0 % ) for the IG ( RR = 0.56 , 95 % CI = 0.35 - 0.89 ) . The incidence density rate of hip fractures per 1,000 RY was 39 for the CG and 43 for the IG ( RR = 1.11 , 95 % CI = 0.49 - 2.51 ) . Other fractures were diagnosed with an incidence density rate of 52 per 1,000 RY for CG and 41 per 1,000 RY for IG ( RR = 0.78 , 95 % CI = 0.57 - 1.07 ) . CONCLUSION The incidence density rate of falls and fallers differed considerably between the control and intervention groups . The study was underpowered to demonstrate a significant difference of hip or nonhip fractures . Because of a low fracture rate in both groups , the investigation of fracture rates would have required a larger sample size to detect an effect of the intervention Abstract A r and omised controlled trial was undertaken to measure effects of exercise on : 1 . Progression of cognitive symptoms related to dementia using the Clock-Drawing Test ( Shulman et al. 1993 ) ; and 2 . Disability using the Revised Elderly Persons Disabilities Scale ( REPDS ; Fleming and Bowles 1993 ) . Data was analysed from 75 nursing home residents with dementia who were r and omly assigned to one experimental group and two control groups . Group 1 ( control ) received no intervention . Group 2 ( control ) received a social visit equivalent in duration and frequency as those undertaking the exercise program in the experimental group , Group 3 . A specifically design ed , frail aged appropriate , twelve-week exercise program was undertaken by the those in the experimental group three times per week . Each session lasted for 30 minutes . Findings from the : 1 . Clock-drawing test showed that exercise may slow the rate of progression of the cognitive symptoms related to dementia ; and 2 . REPDS showed that exercise slowed and reversed disability in some of the activities of daily living One of the effects of Alzheimer 's disease is a diminution in the ability to communicate . A r and omized , non-blinded two-group experimental study was undertaken to determine if planned walking has the capacity to improve the communication performance of patients with moderate to severe Alzheimer 's disease . Thirty subjects meeting NINCDS-ADRDA diagnostic criteria for probable Alzheimer 's disease , selected from two nursing homes , participated in the study . Intervention and comparison groups were each made up of subjects from both nursing homes . Subjects in one group were walked individually for 30 minutes three times a week for 10 weeks . Subjects in the comparison group were engaged in conversation for the same amount of time for 10 weeks . A multivariate analysis of variance ( MANOVA ) was performed on the communication data . 
    Output:
    
Provision of physical rehabilitation interventions to long-term care residents is worthwhile and safe , reducing disability with few adverse events .
Most trials reported improvement in physical condition .
However , there is insufficient evidence to make recommendations about the best intervention , improvement sustainability and cost-effectiveness
