Muscle Imbalance & Strength Testing in Leeds and Bradford: Why Objective Testing Matters
Muscle strength testing can identify weaknesses and differences between muscle groups that may not be obvious during everyday movement or a standard physical examination.
At Light Joints Physiotherapy, we use handheld dynamometry to measure muscle strength and help guide rehabilitation, training and return-to-sport decisions.
Whether you’re recovering from injury, experiencing recurring pain or trying to improve your performance, objective testing can show where you are now and help track your progress.
Strength testing is available as part of our £65 physiotherapy appointments at our clinics in Colton, Rothwell and Greengates.

What Is a Muscle Imbalance?
A muscle imbalance is a difference in strength or function between muscles or muscle groups.
Common examples include:
One leg being stronger than the other
Differences between the quadriceps and hamstrings
Reduced strength following an injury
Weakness affecting movement or exercise performance
Some strength differences are normal. Most people have a dominant side, and perfectly equal strength is not necessary for everyone.
However, a significant weakness may be relevant when it affects your symptoms, rehabilitation or ability to perform specific activities.
What Causes Muscle Imbalances?
Muscle weakness or asymmetry can develop for several reasons, including:
Previous injury: Strength may remain reduced after pain has improved.
Surgery or immobilisation: Reduced activity can lead to muscle weakness.
Training habits: Repeated movements and uneven training loads may contribute to differences.
Pain: Discomfort can temporarily reduce how much force a muscle produces.
Reduced activity: Muscles can lose strength when they are not used regularly.
An imbalance does not always cause pain or injury. Its importance depends on the individual and the demands of their activities.
How Do You Know If You Have a Muscle Imbalance?
Possible signs include:
One leg feeling weaker during squats or lunges
Difficulty pushing or lifting equally on both sides
Reduced confidence after an injury
Difficulty progressing strength exercises
Recurring symptoms during running or sport
One side tiring sooner than the other
These symptoms do not necessarily mean you have a muscle imbalance.
Objective strength testing can help establish whether a measurable weakness is present.
How Do We Measure Muscle Strength?
At Light Joints Physiotherapy, we use a handheld dynamometer to measure the force produced by specific muscles.
This digital device allows us to record strength measurements rather than relying only on how strong a muscle feels during examination.
What Happens During Strength Testing?
Your physiotherapist will:
Discuss your symptoms, injury history and goals.
Assess the relevant joints, muscles and movements.
Position the handheld dynamometer to measure selected muscle groups.
Compare results with the opposite side or previous measurements where appropriate.
Explain the findings and how they affect your rehabilitation or training plan.
Testing is adapted to your condition and physical ability.
Why Is Handheld Dynamometry Useful?
Objective testing can help us:
Identify measurable muscle weakness
Compare strength between sides
Establish a baseline after injury
Track progress during rehabilitation
Adjust strengthening exercises
Support return-to-sport decisions
Handheld dynamometry can provide reliable measurements when appropriate testing procedures are used.
However, results depend on factors such as positioning, technique, pain and testing consistency. Strength testing is therefore interpreted alongside your wider clinical assessment.
Is a 10% Strength Imbalance a Problem?
Not necessarily.
A difference of 10% between sides is sometimes used as a reference point in rehabilitation and sports testing, but it is not a universal threshold for injury risk.
For example, a runner recovering from knee surgery may have different strength requirements from someone attending physiotherapy for shoulder pain.
Your physiotherapist will consider:
The muscle group being tested
Your injury history
Your sport or activity
Pain during testing
Your movement and functional performance
Changes in strength over time
The goal is not always perfect symmetry. It is to develop sufficient strength and function for your individual needs.
Why Is Strength Testing Important After an Injury?
Pain can improve before strength has fully recovered.
Following injuries such as ankle sprains, knee injuries or muscle strains, you may feel ready to return to exercise while still having measurable weakness.
Strength testing can help identify these deficits and guide a progressive rehabilitation plan.
It may also help answer questions such as:
Has my injured leg regained strength?
Am I making progress with rehabilitation?
Which muscles need more work?
Am I ready to increase my training?
Strength measurements are useful, but they are only one part of return-to-sport assessment. Movement quality, sport-specific tasks, symptoms and confidence also matter.
Muscle Strength Testing for Runners and Gym Users
Runners
Strength testing may help identify weaknesses affecting your ability to tolerate running loads, particularly after injury or during rehabilitation.
Your physiotherapist may assess muscles such as the quadriceps, hamstrings, calves and hip muscles, depending on your symptoms.
A strength difference does not automatically mean your running technique is inefficient or that you will develop an injury.
Gym, HYROX and CrossFit Athletes
Objective strength measurements may be useful if you:
Notice one side feels weaker
Struggle to progress certain exercises
Are returning after an injury
Want to monitor rehabilitation progress
Need guidance on increasing training loads
Testing can help identify which muscle groups may benefit from targeted strengthening.
What Happens If Testing Finds a Weakness?
Your physiotherapist will use the findings to help create or adjust your treatment plan.
This may include:
Targeted strengthening exercises
Single-leg or single-arm exercises
Progressive increases in training load
Changes to exercise technique
A gradual return to running or sport
Repeat testing to monitor improvement
The benefit of objective testing is that progress can be measured over time, rather than judged only by how you feel.
Is Muscle Strength Testing Included in Physiotherapy?
At Light Joints Physiotherapy, handheld dynamometry is used where clinically appropriate as part of a physiotherapy assessment or rehabilitation appointment.
Our standard physiotherapy appointment costs £65.
Not every patient needs dynamometry. Your physiotherapist will select the assessments most relevant to your symptoms and goals.

Frequently Asked Questions About Muscle Strength Testing
What is objective muscle strength testing?
Objective strength testing measures the force produced by a muscle using equipment such as a handheld dynamometer. It provides numerical results that can help guide rehabilitation and track progress.
How do I know if I have a muscle imbalance?
You may notice one side feels weaker during exercise or everyday activities. However, strength testing is needed to establish whether a measurable difference exists.
Is a 10% muscle imbalance normal?
A 10% difference is not automatically abnormal or dangerous. Its significance depends on the muscle group, your injury history and the demands of your activities.
Can muscle imbalances cause pain or injury?
Some strength deficits may contribute to difficulties with movement or activity, but an imbalance does not necessarily cause pain or predict injury. Other factors, including training load and previous injury, are also important.
Is handheld dynamometry accurate?
Handheld dynamometry can provide reliable strength measurements when testing is performed consistently using appropriate techniques.
Can strength testing help me return to running or sport?
Yes. It can help measure recovery and guide rehabilitation, although return-to-sport decisions should also consider movement, symptoms, functional performance and confidence.
Does strength testing hurt?
Testing involves producing muscle force against a measuring device. Your physiotherapist will adapt the assessment to your symptoms and ability, and testing should not be pushed through significant pain.
How much does muscle strength testing cost?
Strength testing is used where appropriate within our standard £65 physiotherapy appointments. It is not automatically required for every patient.
Do I need a GP referral?
No. You can book a private physiotherapy assessment directly with Light Joints Physiotherapy.
