Plain English Summary

Background and study aims
A major task facing aging societies is to develop strategies to help older people to stay active. Among the most important means of doing so is the ability to walk safely in one’s environment. Population based information shows that one-half of women and one-third of men aged 75 years and older find it difficult to walk 500 meters. Moreover, approximately 60% of women and one-third of men are unable to walk fast enough (>1.2 m/s) to cross the road during the green traffic light. Problems with walking are associated with poor health, lower participation in society and falls, the majority of which occur while walking. Walking is a complex process involving interaction of the nervous system, muscles and thinking (cognition), which all deteriorate with ageing. Therefore, activities requiring simultaneous physical and cognitive function are especially challenging for older people. The interplay between cognitive functions and walking suggest that both physical and cognitive training has potential for the prevention of walking difficulties in older people. The aim of this study is to investigate the potential benefits of a combined cognitive and physical training program on walking speed, cognition and falls compared to physical training alone.

Who can participate?
Older adults aged between 70 and 85 years who are living at home and have a sedentary lifestyle.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group take part in a physical training program, which involves one to two sessions supervised sessions of 30 to 45 minutes per week of walking exercises and progressive resistance (to build strength) and balance training. Participants are also encouraged to complete exercises at home two to three times per week. Those in the second group take part in the same physical training program with the addition of a cognitive training program, which involves one to two 15 to 20 minutes per week. The cognitive training involves computer-based exercises for working memory (holding, processing, and manipulating information) and executive functions (a set of mental skills that help people to get things done). Participants in both groups complete the programs for a total of 12 months. At the start of the study and then after six and 12 months, participants in both groups complete a number of assessments designed to assess their walking speed, cognition and whether they have had any falls.

What are the possible benefits and risks of participating?
Persons participating in the study will benefit for the participation as they have free access to training programs which have been shown to be beneficial for older people. There may be some risks in this type of physical training interventions. Outdoor walking exercises may increase falls among older populations. In this study, use of walking poles will be recommended during the walking exercises. Falls will be monitored on a monthly basis with diaries. If the program causes a significant increase in the amount of falls participants suffer, the programs will be adapted.

Study information

Scientific title

Promoting safe walking among older people: Physical and cognitive training intervention among older community-dwelling sedentary men and women



Study hypothesis

Primary study aim:
To investigate, in older community-dwelling sedentary men and women, the effects of a 12-month structured progressive physical and cognitive training program (PTCT) on walking speed and dual-task cost in walking speed compared to physical activity (PT) only.

Primary hypothesis:
1. The PTCT will induce significantly greater benefits on walking speed than the PT only. Dual-task cost is smaller after the PTCT intervention than after the PT-only intervention

Secondary study aims:
1. To investigate the effects of the PTCT program on rate of falls during 12-month intervention and a one-year follow-up in the target population compared to the PT only
2. To investigate the effects of the PTCT program on cognition in the target population compared to the PT only

Secondary hypotheses:
1. The rate of falls will be smaller among the PTCT group than the PT group during the intervention and a one-year follow-up.
2. The PTCT will induce significantly greater benefits on cognition than the PT only

Participants are randomised to one of two groups using a computer-generated random allocation sequence of two-fold stratification by gender and age (70-74, 75-79, 80-85) with blocks of 20.

Physical Training (PT) group: Participants receive the multicomponent physical training (PT). This involves undertaking 1-2 supervised sessions of 30 to 45 minutes per week involving walking exercises and progressive resistance and balance training and home exercises. Each participant will attend once a week in supervised walking session. The target intensity will be 13 (moderate value) on the Borg scale. In addition, participants will be advised to walk on their own in order to attain in total 150 min per week by the end of the study. Supervised resistance and balance training will take place once a week in senior gyms. Each training session will include progressive balance training followed by progressive resistance training aiming to improve strength and power for the lower extremity muscles. The training will be performed by pneumatic resistance training machines with SmartCard Software which stores performed workload, sets, reps, and exercise time during each visit. In addition, participants will get a home exercise program including simple balance and functional exercises. The home exercises program is advised to be done 2-3 times/week.

Physical and Cognitive Training (PTCT) group: Participants receive the multicomponent physical training (PT) and a cognitive computer-based training (CT). This involves taking part in PT (as in Physical Training part) and 1-2 supervised cognitive training sessions of 15-20 minutes per week. Progressive cognitive training will include exercises on a computer which target working memory and different components of executive functions. In addition, participants are advised to perform computer-based cognitive exercises on their own 2 times a week.
A diary on all physical and cognitive home exercises will be kept on a daily basis.

A one year follow-up for participants in both groups takes place after the intervention period is complete (12 months) and it involves follow-up for falls with monthly falls calendar.
