Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Timed Up and Go (TUG) test
Tidsramme: At baseline
|
A functional mobility test measuring dynamic balance and gait efficiency.
Participants stand up from a chair, walk 3 meters, turn, return, and sit; longer times indicate higher fall risk.
|
At baseline
|
|
5-Repetition Sit-to-Stand Test (5-rep STS)
Tidsramme: At baseline
|
A lower-limb strength and functional performance test.
Participants rise from a chair five times as quickly as possible; slower performance reflects reduced strength and increased fall risk.
|
At baseline
|
|
Balance test
Tidsramme: At baseline
|
balance assessment is conducted using Baiobit equipment from BTS Bioengineering.
The maximal balance time in monopodalic will be considered (s)

Tidsramme |
|---|---|---|
|
Response time assessment
Tidsramme: At baseline
|
A visual reaction-time assessment using programmable light pods.
Participants respond as quickly as possible to randomly illuminated targets by tapping them, allowing measurement of response time, decision speed, and stimulus-reaction efficiency.
Shorter reaction times indicate better neuromotor responsiveness, while longer delays may reflect reduced processing speed and increased fall-risk vulnerability.
|
At baseline
|
|
Gait Analysis
Tidsramme: At baseline
|
A biomechanical assessment of walking performance using motion-capture technology.
Spatiotemporal parameters (e.g., step length, gait speed, foot clearance) are recorded to evaluate dynamic stability, movement symmetry, and functional mobility, providing objective indicators associated with fall risk in older adults.
|
At baseline
|
|
Physical Activity Questionnaire (IPAQ)
Tidsramme: At baseline
|
A self-reported measure of habitual physical activity.
It quantifies weekly frequency and duration of walking, moderate activity, and vigorous activity, providing an estimate of overall activity level relevant to mobility and fall risk.
|
At baseline
|
|
Falls Efficacy Scale-International (FES-I)
Tidsramme: At baseline
|
A validated questionnaire assessing fear of falling and confidence in performing daily activities.
Higher scores indicate greater concern about falling, which is associated with reduced mobility and increased fall risk.
|
At baseline
|
|
SARC-F questionnaire
Tidsramme: At baseline
|
A screening tool for sarcopenia evaluating strength, assistance in walking, rising from a chair, climbing stairs, and fall history.
Higher scores reflect impaired physical function and greater vulnerability to falls.
|
At baseline
|
|
fall risk questionnaire (FRQ)
Tidsramme: At baseline
|
"The Fall Risk Questionnaire (FRQ) is a validated self-assessment tool.
It has demonstrated good ability to identify older adults at risk of falling and to increase awareness of fall risk within this population.
|
At baseline
|
|
Dual-energy X-ray absorptiometry (DEXA)
Tidsramme: At baseline
|
Gold-standard method for assessing body composition.
By using two X-ray energy levels, DEXA provides detailed information on bone mineral content, lean mass, and fat mass.
|
At baseline
|
|
Strength Assessment
Tidsramme: At baseline
|
Bilateral knee and ankle flexor and extensor strength is assessed using a pressure-based dynamometer.
The protocol includes the measurement of Maximum Voluntary Contraction (MVC, N).
All force signals are sampled at high frequency and processed through filtering and normalization procedures to ensure accurate extraction of mechanical parameters.
|
At baseline
|
|
Power assessment
Tidsramme: At baseline
|
Bilateral knee and ankle flexor and extensor power is assessed using a pressure-based dynamometer.
The protocol includes the measurement of Rate of Force Development (RFD, kg/s through standardized isometric contractions.
All force signals are sampled at high frequency and processed through filtering and normalization procedures to ensure accurate extraction of mechanical parameters.
|
At baseline
|
|
High-Density Surface electromyography Assessment (HD-sEMG)
Tidsramme: At baseline
|
Neuromuscular activity of the knee and ankle flexor and extensor are evaluated using high-density surface electromyography (HD-sEMG) with the Sessantaquattro+ system (OTBioelettronica).
The electrode matrices allow spatially detailed mapping of muscle activation.
EMG signals undergo preprocessing including filtering, artifact removal, and time-alignment with strength trials to provide an integrated characterization of neuromuscular function.

At baseline
|
|
Dominance test (Step-Up Test)
Tidsramme: At baseline
|
This test identifies lower-limb dominance by observing which limb the participant naturally uses first when stepping onto a raised platform.
|
At baseline
|
|
Dominance test (Kicking Test)
Tidsramme: At baseline
|
This test determines limb dominance based on the leg used to kick a ball or target.
The dominant lower limb is the one the participant naturally selects for kicking.
|
At baseline
|
|
Dominance test (Balance Recovery Test)
Tidsramme: At baseline
|
This test identifies dominance by evaluating which limb the participant relies on to regain stability after a perturbation.
The dominant limb is typically the one that steps first when balance is unexpectedly challenged.
