A randomized controlled pilot study assessing the feasibility of combined motor-cognitive training and its effect on gait characteristics in the elderly

OBJECTIVE: (1) To develop a motor-cognition training programme; (2) to evaluate
the ability to recruit and retain elderly people; (3) to assess the effects of
the interventions. DESIGN:
Pilot randomized controlled trial. SETTING: Assisted
living facility. PARTICIPANTS: Sixteen subjects (11 female) living in an assisted
living facility were randomized to a motor or motor-cognition group.
INTERVENTIONS: Both groups received machine-driven strength training and balance
exercises for 45 minutes, twice weekly, for 12 weeks. In addition, the
motor-cognition group received computerized training for attention 3-5 times per
week for 10 weeks. MAIN OUTCOME MEASURES: Baseline and post-intervention (12
weeks) assessments focused on recruitment, attrition and adherence. Secondary
outcome measures assessed dual-task costs of gait (velocity, cadence, step time,
step length), expanded timed get-up-and-go, falls efficacy and reaction time.
RESULTS: Of 35 subjects initially approached, 16 started and 14 completed the
study, resulting in 46% recruitment, 19% attrition and >80% adherence rates.
There is more evidence of altered levels in the motor-cognitive treatment group
with significant differences in average change for fear of falling (P = 0.017)
and foot reaction time (P = 0.046). No statistical significance was reached for
gait parameters. CONCLUSIONS: Motor-cognition training is feasible and shows
trends to stronger improvement in walking and reaction time. The application in a
main study is deemed feasible. A minimum of +/- 55 subjects per group are
required to achieve a power of 80% at the 5% level of significance based on step
length and considering the expectable attrition rate in a required larger scale
study.
