3. The Prone Hip Extension Test The Prone Hip Extension (PHE) Test was one of a series of clinical tests developed by Vladimir Janda as a means of evaluating for motor control deficiencies during specific movements which were proposed to be associated with the development of various musculoskeletal pain syndromes. Neutral alignment at the cervical, thoracic and lumbar spine, while the patient is on prone lying (3, 5), Hip extension and abduction (to the end of available range), followed by knee extension (with the examiner’s one hand holding the anterior aspect of the patient’s distal thigh and the other hand holding the patient’s foot), Clinical Examination of Children with Cerebral Palsy. The ideal order of muscle firing being: Deviations from this pattern or alterations from abnormal recruitment patterns (both amplitude of muscle activation and timing) may result in the observations of the following assumed dysfunctions: 1. They are probably more relevant in specific cases. Deviations from this pattern would therefore indicate dysfunction and dysfunction would then be the cause of all manner of nasty stuff. Stabilisation: Nontest leg dangles or … The research against the test suggests that for the majority of people a delay in Gluteus Maximus is the norm. Some relevant points that I did not even touch on. 2. Hip flexion deformity secondary to acute pyogenic psoas abscess. When they arch backwards it hurts. If not - there is a Weight-bearing Hip/Spine Extension SMCD and/or Ankle Mobility Dysfunction (Refer to ADDS & SLS). GW W 7 ЮU 3 xUra [ t p* 8 ~w fDi9f y r_x5 Q J p ?Wl ϥ lx1W Ł + I T w /ã D . kinematics) that are different than the ideal (e.g. Flexion of the knees occurs suggesting hamstring dominance, 3. Bridge. Pitfalls and important issues in testing reliability using intraclass correlation coefficients in orthopaedic research. Activation patterns and even amplitude can be changed. And it is with this information that I think  people use this test. Alternate Prone Position (Staheli's Prone Hip Extension Test): Start Position: Child in prone lying, legs hanging over end of plinth. Movement: With a slight bend in the knee of the working leg, engage the glutes and hamstring, raising your heel into the air. (aka, hey where is your butt? an individual might hinge at the spine during a squat rather than the hinge because of a weak/inhibited gluteus maximus aka. Clipboard, Search History, and several other advanced features are temporarily unavailable. This is the question of whether there is an optimal way to move and if you don't move in a certain pattern then you are dysfunctional and therefore more prone to injuries. Etiology of the so-called "idiopathic scoliosis". To perform PRONE HIP EXTENSION: 1. 5. 1. They also have a long stride and therefore a low stride rate. Importance of Test: According to Neumann, the head of the femur projects medially and anteriorly to make contact with the acetabulum, thus placing the femoral neck at an angle compared to the table when prone. The "prone hip extension test" is described as a simple, convenient, and reliable method of measuring hip flexion contracture.  |  2. Both Vladmir Janda and Shirley Sahrmann have described its use for decades. of clinical tests developed by Vladimir Janda as a means . You can criticize the test and say that an open chain hip extension test is not at all relevant to what occurs the hip extension during walking. This blog will focus more on the clinical rationale that Janda proposed. 1985 Sep;66(9):620-5. Browse. 2. This type of obvious difference might be something that is relevant. 2001;113 Suppl 4:20-4. She had previously been a subject of mine in the 2004 study. Desensitizing the painful PLE and doing things to desensitize the painful running gait would go hand in hand. 1. Marrè-Brunenghi G, Camoriano R, Valle M, Boero S. J Orthop Traumatol. It is the idea that many of our clinical tests of function might not even be appropriate surrogates for tests of dynamic function. 2019 Jan-Feb;53(1):35-44. doi: 10.4103/ortho.IJOrtho_409_17. New rehabilitation treatment; possibility of prophylactics. NIH These are BIG ROCKS hitting you in the face. Set-up: Begin by lying face down on a lightly cushioned surface. We just need to Reconceptualize the test. To define the relative hip extensor muscle strengths values identified by the 4 grades obtained with a supine manual muscle test (MMT) and to compare these values with those indicated by the traditional prone test. Inter-rater reliability kappa values of standing flexion test, sitting PSIS palpation, and prone knee flexion test are reported as follows: 0.08 - 0.32, 0.23 - 0.37, 0.21 - 0.26 respectively. Please enable it to take advantage of the complete set of features! the spine hinges or twists) are normal and harmless variations on how to move or are indeed painless dysfunctions that are related to current or future injuries. Epub 2012 May 17. The patient then lifts his legs off the floor. Researchers before me had this found this as well (Pierce and Lee , Vogt et al 1997) and many researchers after me (Oh et al 2007, Sakamoto et al 2009). But a painful PLE might be relevant and useful clinically under certain circumstances. Results for both examiners were given to an independent recorder. gluteal amnesia). We can't conclude that the gluteus maximus does not become weak or inhibited. ... • Maitland 18 called this test the quadrant, or scouring, test if the hip was fully flexed. PRONE HIP EXTENSION: Watch the PRONE HIP EXTENSION: exercise demonstration video above. Arms folded across chest or abdomen. Each examiner was blinded to the results of the other examiner. The PHE test was originally described as a means of assessing for the presence of a motor control impairment associated with the gluteus maximus in individuals with LBP. Stud Health Technol Inform. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. “The prone leg extension test is commonly used in the evaluation of lumbopelvic function. Background: Prone hip extension (PHE) is a common and widely accepted test used for assessment of the lumbo-pelvic movement pattern. This might be a case where the pattern is relevant. of ev aluating for motor control deficiencies during specif- For an added challenge, incorporate weights … Purpose:  Provide a mild critique of the utility of the prone hip extension test. The psoas muscle as cause of low back pain in infantile cerebral palsy. Additionally, validity of the results should be evaluated carefully due to the reference standard used for this study. The prone hip extension test (or prone leg extension – PLE) is a very common clinical test in use for more than 20 years. Objectives. Shortening the stride might be enough. It has been theorized that the activation of muscles during a prone leg extension (PLE) simulates the muscle recruitment pattern of hip extension during gait. The patient is then asked to lift a leg off of the table approximately 6 inches. This site needs JavaScript to work properly. Performing the Test: With the patient lying prone on a plinth with his legs fully resting on the ground, the examiners places a posterior to anterior pressure in the lumbar spine. The test may be performed on a padded examining table or bed, it is applicable to the spastic patient, and as the patient is examined prone, it provides a method of flatteni … Maybe we just don't have the best test. We can try to do things to desensitize the pattern. 3. NLM Hip extension during terminal stance may even be mostly passive in that the hip extensors work more to slow the hip down and then accelerate during terminal swing and early stance rather than provide any extensor thrust backwards. Keep them running because this is meaningful. One test which was developed by Janda15, 16, 17 to assess motor control around the lumbar spine is the Prone Hip Extension (PHE) test. COVID-19 is an emerging, rapidly evolving situation. I believe this is why Dr. Sahrman advocates testing hip extension with the starting point of having the hip in 30 degrees of flexion. Both Vladmir Janda and Shirley Sahrmann have described its use for decades. See my post here on the great research of Dr. Cara Lewis. 3. Then go back and try to do the movement again and see if it hurts less. 2002;91:37-46. The lack of hip extension might decrease their movement options so they have to move in a pattern that is already sensitized...they can't/don't move differently to give themselves a break. Grades 3 to 5 - Patient is in prone to test gluteus maximus and hamstrings - side-side knee in extension to test gluteus maximus only - test-side knee flexed to 90° Grades 0-2 - Patient is in side lying ('gravity minimal' position) The prone hip extension test (or prone leg extension - PLE) is a very common clinical test in use for more than 20 years. "Dysfunctional" patterns may not be absolute. Hence, I am no longer a researcher. Two influential clinicians have advocated its use although for slightly different reasons. Hip flexion contractures: a comparison of measurement methods. While it is true that a lack of hip extension during running is compensated for by an increase in anterior pelvic tilt it has also been shown that our static tests for decreased hip extension (e.g. As always, more research is needed but no one wants to do it and no one will pay for it. Its odd, but people often keep doing the same movement/posture adoption even when it hurts. Bartlett MD, Wolf LS, Shurtleff DB, Stahell LT. Arch Phys Med Rehabil. knee valgus, femoral internal rotation) may not consistently correlated with the same dysfunction during running or even be related to Gluteus Medius strength (reference to follow). Briefly, the test asks the patient to lie prone on a plinth, hands palm up at the side of the patient. The examiner applies pressure against the lumbar spine again. It, therefore, circumvents the problems commonly associated with the traditional "Thomas Test". 4. Both Vladmir Janda and Shirley Sahrmann have described its use for decades. We don't need a fancy kinematic explanation. Previous research has found two contradictory patterns of muscle activation during PLE in normal individuals. Maybe we are uncoupling pain from that movement. I have lab EMG research showing that the Glut Max barely fires during walking and this is supported by Dr Lieberman's (of barefoot running fame) EMG work on the role of the Gluteus Maximus during running (see the paper here). So, the research suggests that the originally suggested firing order may not accurate. Just that the rationale behind its use may need to evolve. Two groups of development of scoliosis. I recognize that many esteemed biomechanists and clinicians can provide a very plausible biomechanical or clinical rationale (hence, I admit I use this test occasionally). So, how do you desensitize it? 1. The bridge is a great glute-targeting exercise.  |  Just be sure to check in with your physical therapist or doctor before starting this, or any other exercise. Lets not view the PLE as faulty but just sensitive. Keep doing the symptom modifying exercise hourly for a few days. This is easily observed and doesn't require some magical EMG sensors to built into your eyes to see a muscle activation. The movement is kinematically and symptomatically similar to the painful functional task (running). Lee KM, Lee J, Chung CY, Ahn S, Sung KH, Kim TW, Lee HJ, Park MS. Clin Orthop Surg. The crux of this test is that there is an ideal or optimal way to lift the leg off of the bed. Maybe stretch the hip flexors - can't believe I'm saying it. It won't hurt and this is a case where the impairment may be relevant. We can't discount the idea that a movement pattern that sees the patient spinal hinge or anteriorly tilt their pelvis a great deal rather than merely extending at the hip is not dysfunctional. But I do think you might be able to say that the Gluteus Maximus is not turning on at all. 2012 Jun;4(2):149-55. doi: 10.4055/cios.2012.4.2.149. As long as they don't flare up keep them active. You confront with strength. When patient cannot lie prone or hip extension is EXPECTED to be greater than Grade 2 (poor) use supine Hip extension test. However, even if the criticism is watertight it does not mean that the test is useless. Full disclosure, I use this test with my patients yet I have also published research questioning its validity. The Prone Hip Extension (PHE) Test was one of a series . Epub 2008 Mar 13. r 9 5 [ w@e L9 d ɤC K ] T QU @fnf D (I U] ;|/p 8 Q + 2y e 3 C[$ }[{ 5 ŷ / ~vJ [rr ݳ o = / ^_ {K T f G 7 kU? Do FORM FARTLEKS of 30 seconds of the knee running style and 3 minutes of the old. It is proposed (Rehabilitation of the Spine,  by Craig Liebenson pg 214 -great book by the way) that his hip hyperextension movement is performed to analyse the hip extension that occurs during the terminal stance phase of gait. The patient therefore gets thigh extension from an anterior pelvic tilt rather than the hip actually extending. My research was nothing brilliant or new. This research needs to be done, but it is much a larger question. Load is good. 3. The movement has become coupled with pain. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Instructions . Most research to date only looks at EMG timing. Two influential clinicians have advocated its use although for slightly different reasons. Extension (in Prone) TEST PROCEDURE. This a huge and difficult question. The prone hip extension test (or prone leg extension - PLE) is a very common clinical test in use for more than 20 years. For example, the GMax might be remaining completely flaccid on one side and be hard as rock on the other. Load Globally: General hip, spine and leg exercises help sometimes. In the prone standing position, the hip is flexed and the hip extensor muscle fibers and lever arm are lengthened, allowing for a more favorable length-tension relationship and thus optimizing hip extension moment production . An observable (or palpable) delay or absence of Gluteus Maximus firing. I am not saying that it is dysfunctional, just that no one has proven that it is not (they haven't proven that it is but I am sure a biomechanical - tissue overload argument could be made and is made). USA.gov. Emphasis: Do not push the range of motion by hyperextending the lower back or bending the knee more. In this study, my girlfriend at the time (now wife) sprained her ankle. We found nothing, the variability was huge and it was a mess. The test may be performed on a padded examining table or bed, it is applicable to the spastic patient, and as the patient is examined prone, it provides a method of flattening the lumbar spine under visual control to avoid obtaining either a falsely high or low value. 2. P3 3 "DU q G čM4 S 6~ Ģ6q # U j s ` o N Y . Passively and actively they don't have much hip extension. 8*c j Tn ˄ Z&Қ \ o& + ᳶ Y bn | r0 < * 5 D N & RV& 4 8 % 4a Y_ ʲ 9 Ry 9 ƅ/p 0 o 9 l ༐ڦ %oRGD a ! Prone Hip Extension1 MELINDA NYGREN PIERCE, MS, PT,2 WYNNE A. LEE, PhD3 The purpose of this study was to determine if persons without a history of low back dysfunction use a statistically consistent muscle firing order of left erector spinae, Hinging does not occur at the hip joint rather it occurs in the lower spine. When running it looks like they are very upright and leaning backwards. Physiotherapist, Chiropractor and reformed biomechanist, exercise biomechanics, running biomechanics, Running Injury, 2011. Prone Hip Extension (PHE) Test & Active Straight Leg Raise (ASLR) Test. Performing the prone straight leg raise exercise is simple to do. Audience: Therapists and patients with too much time on their hands f Y{ ז: . Search. A continuing-education service for chiropractors & other manual-medicine providers offering affordable, evidence-informed & clinically applicable subscription to weekly research reviews of evidence-based scientific information, live seminars & online credit-hour courses. Passive Prone Hip Extension Test (10°) Modified Thomas Test FABER Test Hip/SI MD Active Prone Hip Extension Test (10°) DN, DP or FP FN If spine extension was dysfunctional assume hip is normal. It does not really look at amplitude of muscle activation and certainly does not look at the force contributions from the various muscles to the movement. What is possible as well is that you just desensitize this for the short term and perhaps they can go back to running the same way in the future. The painful PLE might give us insight into a HABIT of movement that is painful. Sensitivity/Symptom Modification: Modify the prone leg extension in a billion ways (it doesn't matter how) and have them extend that hip with decreased pain. It has been theorized that a normal and consistent pattern of muscle activation exists. Learn a new habit. We should question rather the PLE is related to the movement that occurs during our functional tasks. Position of patient in Supine Hip Extension? Considerable increased in lumbar lordosis during this test has been considered as impairment of movement patterns in lumbo-pelvic region. I even argued this in a paper I published in 2006 which is often cited to discredit the PLE test (kind of the opposite of what I was going for in my discussion but stuff happens). Wien Klin Wochenschr. If it doesn't no worries. I therefore, had data on her in an uninjured state. Janda proposed that a normal pattern of muscle activation timing occurs during the PLE. I don't think it is valid to look at a the posterior chain and conclude that the glutes are slightly delayed after the hamstrings. Where is the therapist for Grade 5-2? Sometimes it carries over. Two influential clinicians have advocated its use although for slightly different reasons. This area would really be a great PhD and another post. *When I say research, I mean a direct link. [Botulinum toxin treatment of hip adductor spasticity in multiple sclerosis]. PRONE HIP EXTENSION: Targeted Muscles: The Prone Hip Extension is a great exercise to activate the glutes before you complete a deadlift or squat workout. Two doctors of chiropractic simultaneously observed and independently assessed the left and right prone hip extension test on all 42 patients. My initial research in 2004 suggested that a delay in the firing of the gluteus maximus was common in all subjects and the range of timing across muscles is probably something that can not be seen by the human eye.  |  But I was not ready to throw out the test. what the movement looks like). The study was conducted on 30 young healthy subjects, with no history of lumbar, sacroiliac or lower limb injury within the past two years. The "prone hip extension test" is described as a simple, convenient, and reliable method of measuring hip flexion contracture. Other researchers (Stu McGill) have advocated testing its function with the supine bridge. For example, dysfunctions during a single leg squat (e.g. Supine, with patient's heel off end of table. It has been suggested that there exists an ideal movement pattern when lifting the leg off of the table. Biomechanical explanation of spine deformity. Load locally - my guess is that spine stability exercise "work" because you load locally and this has an analgesic and cognitive influence. 4. I immediately rushed her to my lab, through electrodes on her butt (something we already did for fun, just kidding), hamstrings and back and tried to see if this ankle injury influence muscle activation timing over the course of 8 weeks (click here for the study). The patient is asked to extend the hip. Especially, with fat being distributed differently over the different regions. The Prone Hip Extension (PHE) test was originally introduced by Janda and has been adopted in multiple studies to investigate impairments in lumbo-pelvic neuromuscular coordination . HHS In other words, the timing is so close together between 20 and 500 milliseconds that I doubt you can see what muscle turns on first. One biomechanical model suggests that changing the activation patterns and amplitudes can influence anterior hip joint health. Why and how is the pattern relevant clinically? Pause at the top of the motion, and return to the start in control. ), 5.  initiation of hip movement by periscapular muscle activation, The research, tinged by opinion, on this test. My personal opinion is that we can't make this conclusion yet. prone hip extension. 1. 2008 Mar;9(1):43-7. doi: 10.1007/s10195-008-0104-5. Running Changes: EASY-PEASY- 1. shorten their stride and maybe try leaning forward and if all else fails very temporarily have them posteriorly tilt their pelvis (they will hate this but frame it only as temporary). Indian J Orthop. The prone SLR exercise also helps to improve your hip extension active range of motion (ROM). There is no research* investigating whether alterations in form (i.e. In a 2013 study, Kang et al looked at the influence of hip abduction on activation patterns of Gluteus Maximus (GM) and Hamstrings (HAM) in prone hip extension with knee flexion (PHEKF). ...

When the do the prone leg extension test it hurts and it seems like they arch their back a great deal. One study shows an almost simultaneous activation of the lower erector spinae and … Nor does any of the research look at Kinematics (e.g. Deviations from the ideal pattern while prone are indicators of the dysfunction that could be occurring during gait or possible other tasks (e.g. This is assumed to occur because of weakness or inhibition in the Gluteus Maximus. Some interesting work has even looked at changing the timing and the amplitude of muscle activity (Chance-Larson et al 2010, Lewis et al 2009) but they still showed that the Gluteus Maximus fires last BUT it can be taught to fire sooner BUT without actually changing the order of activation. the Thomas test) do not correlate with the amount of hip extension that occur during running. Considerable increased in lumbar lordosis during this test has been considered as impairment of movement patterns in lumbo … Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. NEAT...and I don't know if it is relevant. The prone leg extension (PLE) is a clinical test used to evaluate the function of the lumbopelvis. Here is an example: A runner complains of low back pain while running. Start studying Pelvic Girdle/Hip Pop Test. Prone hip extension (PHE) is a common and widely accepted test used for assessment of the lumbo-pelvic movement pattern. The Prone Hip Extension (PHE) Test was originally developed as a tool to be used to assess the relative activation orders of the ipsilateral hamstring and gluteus maximus muscles and both erector spinae muscles during the movement.
