Popis
Inclusion Criteria:
- aged ≥60 years;
- at risk of sarcopenia and/or prefrailty. At risk of sarcopenia is defined as meeting at least one of the following criteria: SARC-F (Strength, Assistance with walking, Rise from a chair, Climb stairs, and Falls) score ≥4, calf circumference <34 cm for men or <33 cm for women, while prefrailty is defined as a Fried Frailty Phenotype score of 1-2;
- score ≥7 on the Chinese (Hong Kong) version of the Abbreviated Mental Test;
- can stand independently for assessment; and
- can understand and follow intervention and assessment instructions.
Exclusion Criteria:
- absence of full diagnostic criteria is required; therefore residents with confirmed sarcopenia as defined by the Asian Working Group for Sarcopenia 2019 or confirmed frailty as defined by the Fried Frailty Phenotype (score 3-5) will be excluded;
- severe cognitive, sensory, or communication impairments not adequately corrected with aids;
- uncontrolled medical, neurological, orthopaedic, cardiovascular, or psychiatric conditions that preclude safe participation;
- prior experience of regular practice of Tai Chi >1 month; or
- current participation in another clinical trial.
- absence of full diagnostic criteria is required; therefore, residents with confirmed sarcopenia as defined by the Asian Working Group for Sarcopenia 2019 or confirmed frailty as defined by the Fried Frailty Phenotype (score 3-5) will be excluded;
- severe cognitive, sensory, or communication impairments not adequately corrected with aids;
- uncontrolled medical, neurological, orthopedic, cardiovascular, or psychiatric conditions that preclude safe participation;

Experimentální: Exergaming-based sitting Tai Chi
Participants allocated to the intervention group will receive a structured exergaming-based seated Tai Chi program.
The program uses a 12-form seated Tai Chi exergame delivered in 24 sessions over 12 weeks, with each session lasting approximately 60 minutes.
|
The structure and content of the 12-form seated Tai Chi routine build on earlier sitting Tai Chi programs developed by Tsang and colleagues for frail older adults and neurological populations.
The program targets three domains: (i) balance control, (ii) eye-hand coordination, and (iii) limb flexibility.
Training is organized into progressive phases (learning, skill-specific training, and game modes).
Each session begins with a 5-minute warm-up and ends with cool-down stretching and breathing exercises.

Komparátor placeba: General health education
Participants allocated to the control group will attend small-group health education sessions focusing on general health topics relevant to older adults (e.g., oral health, common colds, and skin care) for 24 sessions over 12 weeks, with each session lasting approximately 60 minutes.
|
Health education will be delivered using audio visual materials, brief talks and interactive discussion to provide engaging but non specific information about daily health management.

Maximal handgrip strength
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in maximal handgrip strength (kg) measured with a Jamar Plus+ Digital Hand Dynamometer.
Participants are seated with the elbow flexed at approximately 90 degrees.
Three trials per hand are performed, and the highest value recorded from either hand is used.
Higher values indicate greater muscle strength.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

Skeletal Muscle Mass Index (SMI)
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in skeletal muscle mass index (kg/m²) assessed by multi-frequency bioelectrical impedance analysis (MC-780MA, TANITA).
Appendicular skeletal muscle mass is obtained from device output and divided by height squared to calculate SMI (kg/m²).
Higher values indicate greater muscle mass.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

Lower-Extremity Function (Five Times Sit-to-Stand Test)
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in performance on the Five Times Sit-to-Stand Test.
Participants stand up and sit down five times as quickly as possible from a standard-height chair without using their arms.
Time to completion (seconds) is recorded with a stopwatch.
Shorter times indicate better lower-extremity function.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

Independence in Activities of Daily Living (Katz ADL-C)
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in independence in basic activities of daily living measured by the Chinese version of the Katz Index of Independence in Activities of Daily Living (Katz ADL-C).
Items cover bathing, transferring, dressing, toileting, eating, and continence.
Total scores range from 0 to 6, with higher scores indicating greater dependence in basic activities of daily living.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

|
Change in reaction time measured by a computer-based finger-press reaction task.
Participants respond as quickly as possible when an on-screen box changes color at random intervals.
Mean reaction time is recorded in milliseconds.
Lower values indicate faster reaction time.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

Health-Related Quality of Life on the EQ-5D-5L Utility Index
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in health-related quality of life measured by the EuroQol 5-Dimension 5-Level (EQ-5D-5L) utility index.
Health states are converted to a utility score using the Hong Kong-specific EQ-5D-5L value set.
Utility scores range from values below 0 (health states considered worse than death) up to 1.0 (full health), with higher utility scores indicating better health-related quality of life.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).

Sitting Balance and Functional Reach (Modified Functional Reach Test)
Časové okno: Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
|
Change in sitting balance and forward and lateral functional reach distance (cm) measured by the Modified Functional Reach Test (mFRT).
Participants sit on a backless, standard-height chair with hips and knees at approximately 90 degrees and feet flat on the floor.
With the shoulder flexed to 90 degrees and the elbow extended, participants reach forward and laterally as far as possible without losing balance or taking a step.
The maximal distance reached in each direction by the third metacarpal is recorded using a wall-mounted tape measure.
After two practice trials, three test trials are performed in each direction and the mean distance in each direction is used.
Greater distances indicate better sitting balance and functional reach.
|
Baseline (Week 0), mid-intervention (Week 6, after 12 sessions), post-intervention (Week 12, after 24 sessions), and 3-month follow-up (Week 24, approximately 12 weeks after the final intervention session).
