Nordic Walking to Manage Falls and Fear of Falling

Introduction:

this is a pilot study that aims to test the feasibility and safety of a novel Nordic Walking (NW) activity program for community-dwelling older adults who are at risk of falling or experience fear of falling (FOF). The study also aims to determine the distribution and effect sizes of outcomes to inform future sample size calculations and explore participants' perspectives of the intervention.

Background:

Falls and fear of falling are significant concerns among older adults, leading to physical impairments, psychological trauma, and a decline in abilities and quality of life. Exercise has been shown to be effective in improving muscle strength, balance, mobility, and postural control, all of which are risk factors for falls and FOF. However, traditional exercise programs have limitations in terms of cost, sustainability, and long-term adherence. Nordic Walking, a low-risk and low-tech intervention, has emerged as a promising alternative, offering numerous physical and mental health benefits.

Study Design:

The study will be conducted in two stages. Stage One will involve a two-arm, parallel, single-blind, randomized controlled pilot trial. Forty older adults at risk of falling will be recruited and randomly assigned to either a 10-week NW intervention group or a control group. The intervention group will receive supervised NW training sessions and will be coached to practice independently. The control group will receive regular phone calls to discuss healthy lifestyle habits.

Outcome Measures:

The study will collect feasibility and safety data, including recruitment, adherence, and follow-up rates, as well as adverse events. Effectiveness outcomes will be assessed using measures such as the Timed Up and Go (TUG) test, Stay Independent Falls Risk Assessment Tool, Falls Efficacy Scale-International (FES-I), Activities-Specific Balance Confidence Scale, and the Four-Square Step Test (FSST).

Data Analysis:

Descriptive statistics will be used to characterize participants and feasibility measures. Hedge's effect size and confidence intervals will be calculated. Independent samples t-tests and chi-square tests will be used to compare the intervention and control groups. The main focus of the analysis will be to estimate the effect size, test the intervention's feasibility and safety, and inform future studies.

Sample Size:

The study aims to recruit 40 participants (20 per group) to ensure study robustness and account for potential dropouts.

Stage Two:

In the second stage, qualitative interviews will be conducted with all participants in the intervention group to gather feedback on the acceptability, perceived value, barriers, and facilitators of participating. The data will be analyzed using interpretive description to identify themes and categories.

Inclusion criteria

• Must be 60+ years old.
• Be at risk of falling, as determined by the Stay Independent Falls Risk Assessment Tool. This validated tool is recommended by the STEADI fall prevention program to evaluate risk of falling.

Exclusion criteria

• Inability to use walking poles due to medical conditions.
• Inability to walk 400m independently.
• Having a medical condition such as unstable cardiorespiratory status, impending angioplasty, or ataxia/dyskinesia (unsteady, staggering gait) that prevents them from participating in physical activities or using walking poles is prohibited.
• Taking part in any other structured exercise program.
