Szczegółowy opis

Participants will be randomly assigned to two groups: LiFE-SePBT or an attention control group. All participants will provide their written informed consent before baseline assessment. The study will be reported and conducted in line with the CONSORT statement. Participants will be recruited via convenience sampling in the local community. After baseline assessment, both groups will receive five 90-minute intervention sessions over 10 weeks. Between-group differences in behaviour will be examined before and after training to identify immediate training-induced changes in postural stability. Retention of the changes in postural stability will be assessed four months after the training period. Fall incidents will be followed up for 12 months after training.

Broń i interwencje

Grupa uczestników / Arm
Interwencja / Leczenie
Eksperymentalny: LiFE-SePBT

5 sessions of combined Lifestyle-integrated Functional Exercise and Self-initiated Perturbation-based Balance Training (LiFE-SePBT) will be delivered. The LiFE component involves having participants embed functional exercises into their lifestyle, as well as practising recovering their balance upon self-initiated perturbation. Each session is 90 minutes long and will be hosted once every 2 weeks.

Lifestyle-integrated Functional Exercise and Self-initiated Perturbation-based Balance Exercise (LiFE-SePBT) is a synergistic fall prevention programme. LiFE programme targets generic balance and muscle strength whereas SePBT mainly influences through reactive balance.

Komparator placebo: Attention control group

Participants in the attention control group will receive 5 sessions of upper limb mobilisation and flexibility exercises. Each session is 90 minutes long and will be held once every 2 weeks.

Upper limb mobilisation and flexibility training, including arm circles, deltoid stretches, shoulder internal rotations, etc.

Generic Balance ability
Ramy czasowe: Week 0 (baseline assessment), week 10 (post-assessment), week 22 (i.e., 3-month follow-up assessment)

Generic balance ability will be assessed by the Mini-BESTest. Mini-BESTest can challenge balance across anticipatory postural adjustments, postural responses, sensory orientation and stability in gait, allowing for a comprehensive examination of improvements that occur in reactive control.

Week 0 (baseline assessment), week 10 (post-assessment), week 22 (i.e., 3-month follow-up assessment)

Ramy czasowe
Number of real-life falls
Ramy czasowe: 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, and 12 months after the intervention.

The number of real-life falls in months after randomization will be recorded. Fall circumstances and related injuries will be required via phone contact. A fall is defined as an event resulting in a person unintentionally coming to rest on the ground or other lower level, not as the result of a major intrinsic event (e.g., syncope, stroke, or overwhelming hazard such as an earthquake).

1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, and 12 months after the intervention.
Dynamic balance
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Dynamic balance will be assessed by Alternative Step Test (in the unit of seconds).

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Balance confidence
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Balance confidence will be measured with the Chinese version of the shortened version of Activities-specific Balance Confidence Scale (ABC-6). The scale value is from 0 to 100, with higher values representing higher balance confidence.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Functional lower body strength
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Functional lower body strength will be assessed by Five-time Sit to Stand Test (in the unit of seconds).

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Number of laboratory falls
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Participants will be exposed to one trip-like perturbation and slip-like perturbation on each foot at an unexpected time. The number of falls upon perturbations will be recorded.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Depressive symptoms
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Depressive symptoms will be assessed by Five-Item Geriatric Depression Scale. Participants will be asked to answer 5 questions as yes or no. The answer "no" for the first question and "yes" for the other four questions will be evaluated for depression.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Health-related quality of life
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Health-related quality of life will be assessed by the EQ-5D-5L. In the EQ-5D-5L descriptive system, each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Each health state is identified by a five-digit code, with 11111 representing the best and 55555 the worst possible health state.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Muscle activations
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Muscle activations will be assessed by surface electromyography using an electromyography system (Trigno IM, Delsys Inc., Natick, MA, USA). Fourteen electrodes are placed bilaterally over erector spinae, rectus abdominis, gastrocnemius medialis, biceps femoris, rectus femoris, tibialis anterior, and gluteus medius according to the SENIAM guidelines (www.seniam.org) by the physical therapist.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Physical activity
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.

Physical activity will be assessed by the Physical Activity Scale for the Elderly. This questionnaire will ask participants to recall their activity over the last 7-days. Activity types include sitting, walking, sport/recreation, exercise, occupational and household. A total score for physical activity can be calculated using these answers and the predetermined weights associated with each activity.

Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
Cognitive flexibility and executive function
Ramy czasowe: Week 0, baseline assessment; Week 10, post-intervention assessment; Week 22, follow-up assessment.
