Lateral movement is essential in sports such as basketball, football, soccer, netball and tennis. The Modified Edgren Side Step Test gives professionals a simple field-based way to assess how a client side-steps, crosses over, changes direction and maintains control under time pressure.
It should be used as a performance and progress-tracking test, not as a diagnostic test.
Test name: Modified Edgren Side Step Test
Purpose: Assess lateral agility and planned change-of-direction speed
What it measures: Side-stepping, crossover control, coordination, lateral movement speed and movement rhythm
Equipment: Six cones or markers, flat surface, measuring tape, stopwatch or timing gates
Score: Completion time
Best used with: Edgren Side Step Test, Agility T-Test, Illinois Agility Test, 505 Agility Test, lateral hop test and single-leg balance
Key limitation: It is pre-planned and does not measure reactive agility
The Modified Edgren Side Step Test is a planned lateral agility test. The MAT article describes six cones arranged in a straight line and zigzag pattern, requiring the client to side-step, crossover and move laterally through the course as quickly as possible.
It is used to monitor lateral movement capacity, change-of-direction confidence, coordination and control. It can help identify hesitation, poor rhythm, balance issues or reduced lateral quickness, especially in athletes who need to defend, shuffle, evade or reposition.
The test measures planned lateral agility, side-step speed, crossover coordination and body control. It does not measure diagnosis, injury status, sport decision-making or return-to-sport clearance on its own.
This test may be useful for field sport athletes, court sport athletes, tactical populations, general fitness clients and later-stage rehabilitation clients who are ready for multidirectional movement.
Use six cones or floor markers, a measuring tape, flat non-slip surface, stopwatch or timing gates, and Measurz for recording.
Set up the cones as per the MAT version: six cones in a straight line, approximately 3 feet apart, with three cones positioned on each side of the middle cone approximately 5 feet away to create a zigzag pattern.
Ask the client to complete a progressive warm-up including jogging, lateral shuffles and submaximal changes of direction.
The client starts at the first cone on the left side, facing the right side of the course. On “go”, they side-step to the second cone on the right side, return, then complete the crossover and side-step sequence through the course. Time the attempt from the start signal until the client passes the finish point. Record the time to the nearest tenth of a second. Complete three trials with adequate rest and record the fastest valid time.
The score is completion time. A faster valid time generally suggests better planned lateral change-of-direction performance.
A slower time may suggest reduced lateral quickness, poor coordination, balance difficulty, fatigue, pain, reduced confidence or unfamiliarity with the pattern. Interpret the score with movement quality, pain, symptoms, surface, footwear and related strength or hop results.
Benchmark level: Level 3 — practical comparison guidance.
No high-quality published normative values were found for the exact MAT Modified Edgren Side Step Test setup, cone spacing, timing and scoring method.
Use the client’s own baseline, repeated tests under the same setup, sport demands, pain response, confidence and movement quality. Do not compare this result directly with standard Edgren Side Step Test norms because the course and scoring method differ.
Evidence for the exact MAT Modified Edgren Side Step Test protocol is limited. A related accelerometry study used a modified Edgren Side Step Test along a 4 m path and found that accelerometer-derived total time was not significantly different from stopwatch timing, supporting the potential value of instrumented timing for this type of lateral agility test.
For clinical or coaching use, reliability depends on consistent cone spacing, instructions, footwear, surface, warm-up, timing method, trial number and rest.
Sensitivity and specificity are not applicable for routine use. This is a performance test, not a stand-alone diagnostic test.
Common errors include inconsistent cone spacing, unclear course instructions, crossing the feet differently between trials, cutting corners, slipping, timing inconsistently and comparing results with other Edgren test versions.
The test is planned, so it does not assess reactive agility, opponent response or sport decision-making.
Use this test to monitor lateral movement confidence, assess change-of-direction progress, support return-to-sport progression and complement strength, hop, balance and sprint testing.
Record completion time, trial number, best score, cone setup, surface, footwear, timing method, pain score, confidence, fatigue, symptoms, invalid trials and movement notes. Add comments about hesitation, crossover quality, trunk control, slipping or balance loss.

What does the Modified Edgren Side Step Test measure?
It measures planned lateral agility, side-stepping, crossover movement and change-of-direction control.
Is it diagnostic?
No. It supports performance monitoring and assessment reasoning but does not diagnose injury.
What is a good score?
No exact published benchmark was found for this MAT setup. Use baseline and retesting.
How many trials should be completed?
The MAT article describes three attempts, with the fastest valid attempt used as the score.
Can it be compared with the standard Edgren Side Step Test?
Not directly. The setup, movement pattern and scoring differ.
The Modified Edgren Side Step Test is a practical lateral agility test. Keep the cone setup, timing method, surface and instructions consistent. Use it to track change over time, not to diagnose or clear a client on its own.
