# Single-Legged Timed Side Hop Function Test

This is a timed lateral hop function test requiring consistent line spacing, timing and error criteria.

The Single-Legged Timed Side Hop Function Test assesses repeated side-to-side hopping speed and control on one leg. It is useful for monitoring lateral hop capacity and side-to-side function.

## Introduction

A client may feel confident in straight-line running but hesitate with repeated lateral hopping. This test provides a time-based measure of how quickly and accurately they can move side-to-side on one leg.

## Quick Summary

Test name: Single-Legged Timed Side Hop Function Test  
Purpose: Assess timed single-leg lateral hop function  
What it assesses: Lateral hop speed, endurance, accuracy and control  
Equipment: Marked lines or MAT, timer  
Key finding: Time or reps depending on protocol  
Best used with: Side Hop Test, Square Hop Test, Lateral Hop Test  
Key limitation: Protocol must be clearly recorded

## What Is the Test?

This is a single-leg lateral hopping task performed over a line or between markers while time, repetitions or errors are recorded. The MAT page identifies it as a Power Testing lower-limb function test.

## Why It Is Used

It helps assess repeated lateral hop function, especially when clients need to return to cutting, sidestepping or sport-specific lateral movement.

## What It Measures

It measures repeated lateral hop speed, control, rhythm and tolerance.

## Who It Is Useful For

Athletes, ankle rehabilitation clients, ACL rehabilitation clients and clients returning to lateral movement.

## Equipment Required

MAT or marked lines  
Timer  
Measurz or MAT  
Optional video

## Step-by-Step Protocol

Set up the line or markers.

The client stands on one leg.

Cue the client to hop side-to-side according to the selected protocol.

Time the task or count reps for the selected duration.

Record errors, loss of balance and symptoms.

Repeat on the other leg.

## Scoring and Interpretation

Score time, repetitions and errors according to the protocol. Better performance usually means faster completion or more successful hops with fewer errors.

## Normative Data or Reference Values

No universal values should be applied unless matched to the exact protocol.

## Reliability and Validity

Reliability depends on spacing, timing rules, error definition and trial count.

## Common Errors and Testing Limitations

Common errors include inconsistent line spacing, unclear scoring, counting failed hops and not recording pain or balance loss.

## Practical Applications

Use this test to monitor lateral hop function and compare sides over time.

## How to Record This in Measurz

Record side, line spacing, time or reps, errors, pain, balance loss, fatigue and confidence.

## FAQs

### What does it measure?

Repeated side-to-side single-leg hop function.

### Is it the same as the Side Hop Test?

It is similar, but the exact timing and scoring protocol should be recorded separately.

### Should errors be counted?

Yes. Errors help interpret the score.

## Key Takeaways

This test measures repeated lateral hop function.  
Protocol details matter.  
Record time or reps plus errors.  
Compare sides under identical conditions.
