Timed Up and Go Test

Abstract

The Timed Chair-Stand Test (TCST), frequently referred to as the Five Times Sit to Stand (5xSTS) test, is a rapid and simple performance measure utilized for the evaluative assessment of muscle strength and functional mobility in clinical populations, particularly in older adults. The test requires the patient to complete five consecutive cycles of standing up from a chair and sitting back down as quickly as possible, without using their arms for support. The time taken to complete the task is recorded in seconds by a trained clinician or physiotherapist. This instrument is available in a standard version appropriate for general adult and geriatric populations, as well as a specialized version adapted for individuals diagnosed with Parkinson’s disease.

Purpose

The primary purpose of the TCST is to objectively quantify the dynamic balance, power, and functional strength of the lower extremity muscles, especially the quadriceps and hip extensors. The resulting time score serves as an indicator of the individual’s capacity to execute basic daily activities requiring transitional movements.

In clinical practice, the TCST is invaluable for screening functional decline, establishing baseline performance, identifying individuals at heightened risk of falls, and monitoring the effectiveness of physical rehabilitation or pharmacological interventions, particularly in populations dealing with musculoskeletal or neuromuscular disorders.

Construct

The TCST measures the physiological construct of functional mobility, which encompasses the complex interaction between maximal voluntary contraction, balance, and coordination required for rising from a seated position. The timed metric reflects the efficiency and power output of the muscular system in overcoming gravitational forces.

As a performance-based measure, the score is directly reflective of deficits in the movement system and is highly sensitive to changes in quadriceps weakness or general physical frailty, making it a critical measure in the field of geriatrics and physical therapy.

Validity

The TCST demonstrates robust criterion and concurrent validity. It correlates strongly with other established measures of strength, such as isokinetic dynamometry, and general functional status measures, including gait speed and the Timed Up and Go (TUG) test. Cut-off times derived from large population studies are frequently employed to predict future disability and clinical outcomes, confirming its predictive validity for severe functional limitations and increased fall risk.

Reliability

The test procedure is highly standardized, which contributes to its excellent test-retest and inter-rater reliability. Studies involving diverse populations, including those with arthritis and neurological conditions, consistently report high Intraclass Correlation Coefficients (ICCs), generally exceeding 0.90. This high reliability ensures that changes observed over time are due to genuine changes in the patient’s performance rather than measurement error.

Factor Analysis

While the TCST is a singular performance test, factor analysis studies of comprehensive physical function batteries often confirm that the TCST loads heavily onto a primary factor defined as lower extremity power or dynamic balance. This finding supports the test’s specific measurement focus on the strength components crucial for transferring weight and maintaining independence.

Instrument

Test Type: Performance Measure

Format: Timed physical execution (seconds)

Language Available: Original (English), Dutch Adaptation (KNGF)

Population Group: Adults, Older Adults

Age Group: Typically 60 years and older, but applicable to younger adults with relevant physical impairments.

Population Details: Individuals with musculoskeletal disorders, muscle and tendon disorders, movement system impairments, and neurological conditions (e.g., Parkinson’s disease).

Test Methodology: The subject starts seated with arms crossed over the chest. Upon command, they stand up completely and sit down five consecutive times as fast as possible. The time is recorded from the initial command until the moment the buttocks contact the chair surface after the fifth repetition.

Permissions & Fee and Test Year

The Timed Chair-Stand Test is generally considered a non-proprietary, clinical performance measure. Permissions are typically not required for clinical use, but researchers should cite the original authors (Csuka & McCarty, 1985). There is no associated fee for utilizing the instrument in a standard clinical setting.

The original publication defining the test methodology dates back to 1985. The Dutch adaptation for the Rheumatoid Arthritis guideline was published in 2008.

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

De Timed Chair Stand Test is een eenvoudige evaluatieve test om de spierkracht van ouderen te bepalen. Bij de Timed Chair-Stand-Test wordt de patiënt gevraagd om zo snel als mogelijk 5 keer op te staan van de stoel en vervolgens weer te gaan zitten, zonder dat daarbij de armen worden gebruikt. De fysiotherapeut neemt de tijd in seconden op. Van dit instrument is een originele en Parkinson-specifieke versie beschikbaar.
