Brief Summary

This study aims to evaluate the cognitive function, physical function, and pain levels of community-dwelling older adults to determine the impact of cognitive ability on physical function and pain. It also seeks to establish foundational data for strategies to prevent dementia and sarcopenia. Therefore, the purpose of this study is to measure the cognitive function (overall cognition, executive function, memory, attention, etc.), physical function (muscle mass, muscle strength, gait and balance ability), and pain of community-dwelling older adults, and to analyze the correlations between these factors.

Conditions

Healthy Older Adults

Outcome Measures

Primary Outcomes (5)

• Overall cognitive function: MoCA-K

  Cognitive function will be assessed using the MoCA-K.

  From enrollment to the end of evaluation within 1weeks

• Skeletal Muscle Mass Index

  The skeletal muscle mass index is the sum of limb muscle mass divided by the square of height (kg/m²).

  From enrollment to the end of evaluation within 1weeks

• Grip strength

  Grip strength will be measured using a dynamometer. The subject will sit in a chair with arms extended, elbows bent at 90 degrees, forearms at a natural angle, and wrists in a dorsal flexion position between 0 and 30 degrees. The subject will grip the dynamometer for 3 seconds, and the average value (kg) will be recorded after 3 attempts.

  From enrollment to the end of evaluation within 1weeks.

• Lower Limb Strength

  5 Sit-to-Stand (5xSST) measures the time (seconds) it takes for the subject to transition from a seated position to a standing position and back to a seated position five times. A shorter time indicates better muscle strength. The subject is instructed to cross their arms over their chest, avoid leaning their back or legs against the chair, and perform the sit-to-stand motion five times as quickly as possible.

  From enrollment to the end of evaluation within 1weeks.

• Level of musculoskeletal pain

  For participants with musculoskeletal pain, the level of pain will be assessed using the Numeric Pain Rating Scale (NPRS), where 10 indicates the most severe pain and 0 indicates no pain.

  From enrollment to the end of evaluation within 1weeks.

Secondary Outcomes (7)

• The Word Memory Test

  From enrollment to the end of evaluation within 1weeks.

• Executive function and attention

  From enrollment to the end of evaluation within 1weeks.

• Executive function

  From enrollment to the end of evaluation within 1weeks.

• Subjective Cognitive Decline

  From enrollment to the end of evaluation within 1weeks.

• Static Balance in Three Positions

  From enrollment to the end of evaluation within 1weeks.

Eligibility Criteria

• Age: 65 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Participants in this study will consist of community-dwelling adults aged 65 years or older who use local senior welfare centers and voluntarily agree to participate in the research.

You may qualify if:

• Community-dwelling adults aged 65 years or older who are able to walk independently

You may not qualify if:

• Individuals with severe cognitive impairment that makes test participation difficult (e.g., diagnosed dementia)
• Individuals with acute neurological injury within the past 6 months (e.g., stroke)
• Individuals for whom gait testing is not feasible for safety reasons
