# Single-Leg Sit-to-Stand Test: Max Repetition

Evidence-informed assessment education article for Measurz, Kajabi, Gleap and blog use.

The Single-Leg Sit-to-Stand Test assesses unilateral lower-limb performance by requiring the client to stand from a seated position using one leg. Research has reported inter-rater and test-retest reliability for single-leg sit-to-stand methods when chair height, setup and scoring are standardised.

## Introduction

Single-leg sit-to-stand testing provides a practical way to assess unilateral lower-limb control, strength-endurance and task capacity.

## Quick Summary

**Test name:** Single-Leg Sit-to-Stand Test  
**Category:** Unilateral lower-limb performance  
**Primary scores:** Able/unable, time or repetitions  
**Best use:** Side-to-side comparison  
**Key limitation:** Chair height strongly affects difficulty.

## What Is the Assessment?

The client stands from a seated position using one leg.

## Why It Is Used

Used to assess unilateral lower-limb performance, control, strength-endurance and side-to-side differences.

## What It Measures

It may reflect quadriceps capacity, hip control, balance, trunk strategy, confidence and symptom response.

## Who It Is Used For

Useful for athletes, general fitness clients and lower-limb performance monitoring.

## Equipment Required

-   Chair or box of recorded height
    
-   Stopwatch or **Measurz stopwatch**
    
-   **Measurz rep counter** if repetitions are counted
    
-   Optional **Measurz AR measurement** for chair height
    
-   Optional inclinometer
    
-   MAT tools for related isometric knee or hip strength testing
    

## Step-by-Step Protocol

1.  Client sits on a recorded-height chair or box.
    
2.  One foot is placed on the floor; the other leg is lifted.
    
3.  Arms are standardised.
    
4.  Client stands fully using one leg.
    
5.  Record success, time or repetitions.
    

## Scoring and Interpretation

Score may be able/unable, time for repetitions, number of reps or movement-quality rating.

## Normative Data, Benchmarks or Reference Values

Broad norms are limited. Use chair-height progression, side-to-side comparison and baseline/retest performance.

## Reliability and Validity

Research supports inter-rater and test-retest reliability for single-leg sit-to-stand methods when standardised.

## Common Errors and Limitations

Using the non-test leg, excessive momentum, knee collapse, trunk lean, inconsistent chair height and incomplete standing.

## Practical Applications

Useful for unilateral lower-limb monitoring, side-to-side comparison and progression tracking.

## How to Record This in Measurz/MAT

Record side, chair height, success/time/reps, pain, symptoms, compensations and retest date.

## FAQs

**What does it measure?** Unilateral lower-limb performance.  
**Does chair height matter?** Yes, strongly.  
**Should both sides be tested?** Yes.  
**Are there norms?** Broad norms are limited.

## Key Takeaways

-   Practical unilateral test.
    
-   Chair height must be recorded.
    
-   Side-to-side comparison is key.
    
-   Reliability depends on standardisation.
    
-   Measurz can track height, side and reps.
