KneeMuscle Energy Technique (MET)General regional overview
PNA Regional Principles · Overview
Knee — Muscle Energy Application
What changes when Muscle Energy Technique (MET) meets the knee? Start with the patient's movement, assess safely, and see what the re-test reveals.
3 specific variationsClinical re-test built in
Important: this is a clinical framework, not a complete technique protocol.
This page was generated from broader regional principles. It can help you frame assessment, patient comfort, safety and reassessment, but its generic positioning, contact and dosage text must not be treated as technique-specific hands-on instruction. Study a detailed, individually authored procedure and use supervised practical training.
Each variation below is written so you can follow patient setup, contact, direction, dose and the re-test that decides whether the technique earned a place in the plan.
01
KneeHamstring muscle group
Hamstrings — MET
One question matters more than the name of this variation: will the patient notice a useful change in Straight-leg raise angle, active knee extension and a functional bend/reach task.? The careful re-test gets the final word.
The change we are looking for
Improve hamstring-related posterior-thigh restriction and straight-leg-raise tolerance when muscle length is clinically relevant.
Primary target
Hamstring muscle group
The movement that tells us
Straight-leg raise angle, active knee extension and a functional bend/reach task.
Patient focus
Improve hamstring-related posterior-thigh restriction and straight-leg-raise tolerance when muscle length is clinically relevant.
Therapist verifies
Straight-leg raise angle, active knee extension and a functional bend/reach task.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in straight-leg raise angle, active knee extension and a functional bend/reach task. without symptom worsening.
Full clinical application
1
Position the patient
Supine. Flex the hip with the knee near extension until the first comfortable hamstring barrier; keep the pelvis neutral and the opposite leg supported.
2
Set the contact
One hand supports the distal leg/heel. The other stabilizes the thigh or pelvis so the patient cannot posteriorly tilt the pelvis to escape the barrier.
3
Apply the technique
Ask the patient to gently push the heel downward into hip extension against the therapist's resistance. After 5–10 seconds, relax completely and move only to the new comfortable SLR barrier.
4
Dose & re-test
3–5 contractions at roughly 10–20% effort. No bouncing and no painful end-range stretch. Re-test: Straight-leg raise angle, active knee extension and a functional bend/reach task.
Clinical pearl
A stronger contraction is not better. Low-load contraction plus a clean pelvic position usually gives a more useful response.
Safety / avoid
Stop if symptoms feel neural rather than muscular or if pain radiates distally.
02
KneeQuadriceps, especially rectus femoris
Quadriceps / Rectus Femoris — MET
One question matters more than the name of this variation: will the patient notice a useful change in Knee flexion ROM, prone knee bend/Ely-type response and squat or stair comfort.? The careful re-test gets the final word.
The change we are looking for
Improve knee-flexion tolerance and anterior-thigh tightness when quadriceps/rectus femoris restriction is clinically relevant.
Primary target
Quadriceps, especially rectus femoris
The movement that tells us
Knee flexion ROM, prone knee bend/Ely-type response and squat or stair comfort.
Patient focus
Improve knee-flexion tolerance and anterior-thigh tightness when quadriceps/rectus femoris restriction is clinically relevant.
Therapist verifies
Knee flexion ROM, prone knee bend/Ely-type response and squat or stair comfort.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in knee flexion rom, prone knee bend/ely-type response and squat or stair comfort. without symptom worsening.
Full clinical application
1
Position the patient
Prone or side-lying. Flex the knee to the first comfortable anterior-thigh barrier while keeping the pelvis neutral; add only a small amount of hip extension if rectus femoris is the target.
2
Set the contact
Stabilize the pelvis/hip with one hand and control the distal tibia/ankle with the other.
3
Apply the technique
Ask the patient to gently straighten the knee against resistance. Relax fully, then increase knee flexion only to the new comfortable barrier without lumbar extension or pelvic lift.
4
Dose & re-test
3–5 contractions of 5–10 seconds at low effort. Re-test: Knee flexion ROM, prone knee bend/Ely-type response and squat or stair comfort.
Clinical pearl
Pelvic stabilization is essential. If the pelvis tips forward or the lumbar spine extends, the technique loses specificity.
Safety / avoid
Avoid forceful knee flexion after acute knee injury or when postoperative flexion limits are present.
03
KneeGastrocnemius
Gastrocnemius — MET
One question matters more than the name of this variation: will the patient notice a useful change in Weight-bearing lunge with knee straight, ankle dorsiflexion and gait push-off/stride.? The careful re-test gets the final word.
The change we are looking for
Improve ankle dorsiflexion with the knee extended when gastrocnemius length is a limiting factor.
Primary target
Gastrocnemius
The movement that tells us
Weight-bearing lunge with knee straight, ankle dorsiflexion and gait push-off/stride.
Patient focus
Improve ankle dorsiflexion with the knee extended when gastrocnemius length is a limiting factor.
Therapist verifies
Weight-bearing lunge with knee straight, ankle dorsiflexion and gait push-off/stride.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in weight-bearing lunge with knee straight, ankle dorsiflexion and gait push-off/stride. without symptom worsening.
Full clinical application
1
Position the patient
Supine or long sitting with the knee straight. Move the ankle into dorsiflexion to the first comfortable calf barrier.
2
Set the contact
Stabilize the tibia and hold the calcaneus/forefoot so the movement occurs at the ankle rather than through midfoot collapse.
3
Apply the technique
Ask the patient to gently plantarflex against resistance. Relax, then take up the new dorsiflexion range with the knee still extended.
4
Dose & re-test
3–5 contractions of 5–10 seconds. Re-test: Weight-bearing lunge with knee straight, ankle dorsiflexion and gait push-off/stride.
Clinical pearl
Compare knee-straight and knee-bent dorsiflexion; that helps separate gastrocnemius from soleus limitation.
Safety / avoid
Do not apply calf manual techniques when DVT is suspected.
Safety / do not apply when…
Avoid routine manual therapy with suspected DVT, fracture, acute instability, infection or uncleared postoperative restriction.
Stop or modify if symptoms peripheralize, neurological status worsens, the response is disproportionate or the patient asks to stop.
Clinical rule
A technically correct technique is not automatically a useful technique. Keep it only when the patient's pain, range or function improves in a clinically meaningful way, then transfer that gain into active movement, loading or self-management.
