The Influence of Sway Posture_dralisongrimaldi infographic

Standing posture, hip joint loads & the management of hip pain

In recent years, particularly in the social media sphere, there has been a lot of negative publicity directed towards management approaches for musculoskeletal pain that incorporate postural and/or movement training.

The criticisms usually hang on two main assertions:
1. Postural and/or movement training will induce hypervigilance and fear avoidant behaviour &
2. That the body is robust and will simply adapt to overcome any loading scenario

I would certainly agree that there are potential adverse effects associated with health and exercise professionals leading people to believe there is only one ‘correct’ posture, or teaching people to consciously maintain some inefficient form of active muscle holding – most commonly an abdominal or gluteal contraction in the context of hip pain presentations. However, we cannot completely ignore the influence of loads encountered during sustained postures or repetitive movements. We are all affected by gravity and how we position our body segments relative to gravitational forces, strongly influences the distribution of loads across our bones, joints and soft tissues. Sustained or repetitive end-range hip postures or movements will result in disproportionately high edge-loading (loading around the outer edge of the joint), and increased loads on the adjacent soft tissues. It’s simple physics really. Whether this disproportionate or excessive load ever results in tissue damage, pain or dysfunction is another matter. In the development of pathology, multiple factors are usually implicated, and different combinations of factors are at play for different individuals. There is also a well-accepted disconnect between pain and pathology.

And yet …
o Local tissue pathology and inflammation are associated with nociception
o Local tissue pathology and inflammation could be considered an important risk factor for the development of pain

Although pain and pathology are not well correlated, it does not follow that local pathology and nociception are irrelevant to the management of pain, particularly in the presence of irreversible pathology such as degenerative joint change. Providing targeted load management advice including postural and movement training, using appropriate dialogue does not need to induce hypervigilance but can instead for some individuals lead to rapid changes in pain, function, self-efficacy and quality of life.

As to the assertion that the body is robust and will simply adapt to overcome any loading scenario … there will always be a limit to what the body can adapt to and this limit will vary for each individual. It will depend on many other factors – genetics, morphology, general systemic health, musculoskeletal conditioning, prior injury etc. Commonly attached to the ‘body is robust’ argument is some example of a highly conditioned elite athlete with poor biomechanics. It does not translate that the deconditioned patient in front of us in the clinic, with genetic and morphological predisposition and a history of past injury, should be able to simply ‘adapt’ to adverse loading scenarios induced by their postural or movement strategies.

Load management is now a well-accepted strategy for management of musculoskeletal pain. If the issue is simply a training error – too much too soon – then of course, reducing training load and gradually building up again, allowing time for adaptation is an appropriate solution. However, if the relative overload is underpinned by habitual sustained or repetitive loads which have become part of natural postural and movement patterns or sporting technique, the problem is unlikely to be solved for the longer term by simply unloading and gradually reloading involved structures.

Case Scenario Application

Let’s look at a specific example around the hip. Consider a young woman who presents with anterior hip pain in the context of mild acetabular dysplasia. Her pain is exacerbated by prolonged standing and walking, particularly walking at a fast pace or for more than 30 minutes. She aims to get her 10,000 steps per day, which usually includes a 30-45 minute walk but finds that if she’s been on her feet a lot during the day, her hip aches at night. On examination, you note she stands and walks in relative posterior pelvic tilt and anterior translation of the pelvis (often referred to as ‘sway’ type posture). She is positive on clinical tests for an intra-articular source of nociception.

What effect is this pelvic posture likely to have on our patient’s anterior hip structures and joint loading?

 

The Influence of Sway Posture_dralisongrimaldi infographic

 

While some say that standing posture has no relevance to dynamic function, pelvic posture in standing tends to strongly influence hip and pelvic mechanics in gait. I am yet to see someone in clinical practice who stands in a ‘sway’ (posteriorly pelvic tilted) posture and then suddenly flips into anterior pelvic tilt to walk.

How does walking in a sway posture influence kinematics and hip joint forces in gait?

Lewis and Sahrmann1 provided insights here by collecting kinematic and force plate data during walking with different postures. Walking in the swayback posture resulted in a higher peak hip extension angle and a higher hip flexor moment (to resist the higher forces moving into hip extension) compared to natural posture. In previous research, these authors had already established that a 2° increase in hip extension angle resulted in a very meaningful increase in anterior hip joint forces of approximately 20% of body weight 2. Walking in a sway posture, in relative posterior pelvic tilt and anterior translation will therefore be key contributors to greater hip extension and higher anterior hip joint forces.

 

Hip extension and anterior hip loads in gait_dralisongrimaldi infographic

 

Can modifying pelvic posture in gait alter pain & function?

For patients presenting with anterior hip pain who walk with a sway posture and/or excessive hip extension, reducing hip extension by altering pelvic posture and/or stride length can have a marked and immediate effect on pain and function3. It may also be appropriate to provide an exercise program to address muscle impairments and improve dynamic support of the anterior hip. However, if posture and gait patterns are not addressed, long term control of symptoms is less likely to be achieved with targeted exercise alone, particularly as most people will drop off with their exercise program once short-term pain relief is achieved. For appropriately selected individuals, using appropriately selected dialogue and cueing, postural and movement training can have marked and lasting positive effects.

Intraarticular pathology – relevance to hip pain and joint health – Part 2

In Part 2 of this blog on intraarticular pathology, we explore the relevance of ligamentum teres tears, and effusion-synovitis.In Part 1, we discussed the relevance of labral tears, chondral pathology and bone marrow lesions with respect to hip pain and joint health. If you haven’t read Part 1 yet, you might like to go there first and then return to continue reading.

3. Ligamentum Teres Tear

The ligamentum teres (LT) contains both nociceptive and proprioceptive nerve endings, with a stable innervation pattern that persists with ageing (Haversath et al 2013). The relationship between LT pathology and nociception remains unclear with limited and variable reports of prevalence in symptomatic and asymptomatic populations. A recent systematic review and meta-analysis concluded however, that LT pathology was more common in those with hip pain (Heerey et al 2018).

Ligamentum teres tear is more likely to be present in athletes and particularly athletes whose joints are challenged by large ranges of motion (Mayes et al 2016) or the presence of morphological variations such as FAI, acetabular dysplasia or capsular laxity (Martin et al 2019). Presence of LT tear has been associated with persistent hip pain in those with labral tears, such that in one study, those with LT and labral tear were 16.5 times more likely to fail non-surgical treatment and progress to a surgical intervention that those with labral tear alone (Kaya et al 2013).

For patients presenting to clinic with joint-related pain who:

  • have pain +/- a feeling of instability in sumo-style squats/deep plie, or rotational tasks
  • are slower to respond to standard joint care
  • are/have been athletic
  • and/or have morphological variants (FAI, Acetabular Dysplasia, Capsular laxity),
    be suspicious of LT pathology.

You may need to provide more specific exercise therapy to optimise joint support in positions that challenge the LT.

With regard to the potential impact of LT pathology on joint health – from a joint stability standpoint, loss of integrity of the LT will reduce joint stability particularly in deep flexion/external rotation, end range rotation and distraction. LT pathology may be associated with microinstability, particularly in those with other morphological risk factors, with potential predisposition to early joint deterioration. LT pathology is also frequently associated with signs of inflammation of the synovium that surrounds the ligament, clearly visualised at the time of arthroscopy (Figure) and there is often accompanying inflammatory change in the adjacent pulvinar fat pad. We’ll discuss the role of inflammation in degenerative joint disease in the following section.

Learn more about the ligamentum teres, pathology and implications for management in my online learning course: Anterior Hip & Groin Pain. Specific load management and therapeutic exercise strategies are covered in the practical workshop of the same name.

4. Joint Effusion-Synovitis

Effusion of the hip joint is much harder to clinically appreciate than that of other peripheral joints, due to the depth of this joint and the fact that it is encapsulated by layers of muscular structures. And yet effusion and synovitis have been associated with pain and implicated in the pathogenesis and progression of osteoarthritis (Eymard et al 2017, Hunter et al 2013, Sokolove & Lepus 2013).

The joint capsule and its synovial lining are richly innervated and a potential source of nociception (Haversath et al 2013). The synovial lining of the LT, as we have discussed, will also be a possible contributor to hip joint nociception. Less commonly considered is the possible role of highly vascularised and innervated intra-articular fat pads in hip pain and joint health. Jayasekera and colleagues (2014) described a fat pad at the anterior head-neck junction, that may become hypertrophied and inflamed secondary to repetitive femoroacetabular impingement in those with cam morphology. They hypothesised that for some patients with FAI, their pain was primarily related to this traumatised fat pad and not their labral pathology. They demonstrated that, even though the groups had no difference in cam size, if the impingement viewed arthroscopically appeared to be primarily of the fat pad rather than of the bony cam, surgical excision of the fat pad without a femoral osteoplasty returned results equal to that of cam excision.

Infographic_Effusion Synovitis_dralisongrimaldi.com

 

There is also another important fat pad within the medial hip joint, the pulvinar fat pad, intimately associated with the LT and its synovium. Arthroscopists commonly note visual inflammation of this fat pad in association with synovitis of the LT. Eymard and colleagues (2017) suggest that intra-articular fat pads and their adjacent synovium should be considered unique functional units. Intra-articular fat pads of the knee and hip are composed of smaller fat cells (adipocytes) with an inflammatory phenotype characterised by a higher expression and secretion of inflammatory factors than subcutaneous fat. These intra-articular fat pads may upregulate their expression of inflammatory mediators in response to excessive mechanical loads, subsequently stimulating an inflammatory response in the synovium. The functional interaction between intra-articular adipose and synovial tissue may be a mechanism underlying OA related synovitis, with potential impacts on pain and joint health. Synovitis can drive chondral degradation and osteophyte formation and is considered to play a critical role in the pathogenesis and progression of osteoarthritis (Wang et al 2018).

What this means for healthcare practitioners is that we must be mindful of the possible presence of effusion and synovitis in those with hip joint related pain, the implications for nociception and joint health, and the potentially vital role of load management in the long term care of your patient’s hip.

Further detailed information about effective management of intraarticular hip pain is available within my video lecture series within the online learning course, Anterior Hip & Groin Pain.

In the last 2 blogs, a number of possible sources of nociception for those with intra-articular hip pain have been highlighted. All of these structures play an important role in maintaining joint homeostasis and health, although sources of nociception and mechanical and inflammatory drivers of pain and pathology will vary between individuals. Optimal outcomes may be best achieved by considering an individual’s joint status and morphological, functional and inflammatory drivers, within a biopsychosocial framework.

Intraarticular pathology – relevance to hip pain and joint health – Part 1

With ever-increasing resolution of imaging modalities, pathology within the hip joint is easier to identify and locate.
There is however, a well-accepted mismatch between pathology and pain.

So, is all pathology irrelevant?
How do we sort out what might be meaningfully associated with pain and relevant to future joint health?

Some pathologic features are common in both symptomatic and painfree populations, while others occur more frequently in those with hip pain. The other consideration is whether structural change may have an impact on joint loading and longer-term joint health. If so, preventative education and exercise strategies may be warranted.

In the next 2 blogs we will explore 4 key pathological changes that are regularly identified in imaging and discuss their possible relevance for pain and joint health.

1. Labral Tear
2. Chondral & Bone Changes
3. Ligamentum Teres Tear
4. Joint Effusion-Synovitis

In today’s blog, we will start with the first two topics, labral tears and chondral and bone changes.

1. Labral Tear

The acetabular labrum does contain nerve fibres for nociception and for proprioception (Alzaharani et al, 2014, Haversath et al 2013), meaning that damage to this structure may contribute to hip joint related pain and also to joint protection. However, a recent systematic review and meta-analysis of the prevalence of labral pathology, revealed that while 62% of those assessed with hip pain had labral tears present on imaging, 54% of those without hip pain also had labral tears (Heerey et al 2018). Therefore, while the labrum may be a source of nociception, presence of labral pathology may be irrelevant to the pain presentation of an individual who presents to your clinic with positive imaging findings.

Infographic_Hip Pain & Health_Labral Tear_dralisongrimaldi.com

Labral dysfunction is likely to have wider implications beyond pain. The labrum, despite only absorbing 1-2% of weightbearing loads in a hip with normal bony coverage (Henak et al 2011), has some very important functions in joint stability and chondral protection. The labrum deepens the socket and seals the joint, creating an important suction effect with negative intra-articular pressure. This vacuum increases stability and traps fluid between the head of the femur and the acetabulum to assist with cushioning impact loads (Bsat et al 2016). Injury and surgical debridement will result in a loss of the normal fluid seal, reduction of the efficiency of the vacuum, impacts on synovial flow, increased compression of cartilage due to loss of interstitial fluid and higher loads on the capsule. Debridement of the labrum has a significantly greater effect on reducing these joint protection mechanisms than the tear itself, and there is an absence of high-quality evidence for isolated labral debridement (Philippon et al 2014, Nepple et al 2014). Labral reconstruction does at least partially restore these mechanisms and yet, technical difficulty is much higher, availability is not widespread, indications are not clear, and outcomes have again not been well established.

An initial trial of non-surgical load management and exercise strategies with a well-informed physiotherapist is highly recommended for hip pain in the context of an isolated labral tear, prior to consideration of any surgical intervention. Where surgery is warranted, reconstruction would appear to be a superior alternative, when available. A risk-benefit analysis should be discussed with the patient considering a surgical intervention. In particular, a patient must understand that labral debridement does not ‘fix’ their hip.

Further detail on this topic is explored in the online learning course: Anterior Hip & Groin Pain, including discussion of load management and exercise strategies for pain associated with intra-articular hip pathology.

2. Chondral & Bone Changes

While there is a much higher prevalence of cartilage defects on imaging in those with hip pain compared with asymptomatic individuals (64% vs 12%) (Heerey et al 2018), cartilage is aneural and therefore not a source of nociception. The relationship between chondral damage and pain is most likely mediated by associated changes in other nociceptive structures such as the adjacent subchondral bone and the capsule with its highly innervated synovial lining.

Bone marrow lesions are much more likely to occur in those with painful hips, and subchondral bone is certainly innervated and may be a source of nociception. Bone marrow lesions are identified on MRI as regions of high signal uptake and therefore higher water content associated with increased bone turnover and increased angiogenesis secondary to bone remodelling processes (Shabestari et al 2016). Subchondral bone changes are usually most evident in regions of cartilage deterioration but may occur prior to the visualisation of cartilage change on imaging. For this reason, it has been suggested that subchondral bone pathology may lead to cartilage degeneration due to alteration of biomechanical force distribution or via release of biomediators that influence cartilage health (Barr et al 2015). Disturbance in the normal homeostasis of subchondral bone results in increased bone turnover, volume and change in stiffness with reduced shock absorbing capacity. If the subchondral bone becomes relatively stiffer, the adjacent cartilage will be forced to absorb more shock, potentially inducing degenerative change in the chondral surface that is unable to adequately attenuate these higher loads (Barr et al 2015).

Infographic_Hip Pain & Health_Chondral & Bone_dralisongrimaldi.com

It is interesting to speculate that ability of the chondral surfaces to absorb load may also influence subchondral bone health. For example, labral pathology and associated impairment of the fluid seal of the central compartment is known to increase cartilage consolidation during loading. If the cartilage, which may still appear normal on imaging, is unable to absorb these increased loads, they will be transmitted to the subchondral bone. Failed bone adaptation may result in redistribution of the loads back to the chondral surface, potentiating the degenerative process. Wherever the process begins, there is evidently an intimate relationship between subchondral bone and the adjacent cartilage with respect to osteochondral load sharing, degenerative change and pain.

As cartilage is avascular, it is reliant on diffusion from subchondral bone vessels and from the synovial fluid, for its nutrition. Interference with either of these sources of nutrition may have adverse effects on chondral health. It has been shown that the primary source of chondral nutrition is from the synovial fluid (Wang et al 2018). If this fluid however contains high levels of inflammatory exudates from the synovium, these may adversely influence cartilage health (discussed in the upcoming blog – Part 2, section 4). Conversely, synovial inflammation (and nociception) may be induced by chondral debris and release of soluble cartilage matrix macromolecules into the synovial fluid, secondary to chondral damage (Atukorala et al 2016).

Learn more about morphological, movement and muscle factors that influence hip joint chondral health and strategies to minimise adverse effects, in my online learning course and practical workshop: Anterior Hip & Groin Pain.

In summary then, while the labrum is capable of nociceptive signalling, labral pathology is almost as common in those with asymptomatic hips, so the presence of a labral tear on imaging cannot be presumed to be responsible for hip pain. However, a loss of integrity in the labrum does have implications for long term joint health. Surgical debridement does not ‘fix the labrum’ and restore its function, in fact, it may further reduce its joint protective functions. Closely consider your advice around when/if surgical intervention is required for the painful hip with labral pathology. Chondral pathology and bone marrow lesions are more common in those with hip pain, with health of these tissues and the surrounding synovium intimately related.

In our next blog, we will discuss the relationship between ligamentum teres tear, effusion-synovitis, hip pain and joint health.

In the meantime, keep those hips healthy!

An Exciting Initiative – Hip Pain Help

Today I have some exciting news about a new initiative to connect those in the community suffering with hip and pelvic pain, and health professionals with a special interest in this field. Chances are, that if you’re visiting this site, you fall into one of those two groups, so this is great news for all of you!

Over the last 3 years, my colleagues, Sharon Hennessey and Kirsty McNab, and I have been developing our new website Hip Pain Help. This was born out of a clear need to connect those in pain with high quality help. Every day I receive emails with heartbreaking personal stories of avoidable ‘wrong turns’ in the management of hip or pelvic pain. They tell me how delays in their diagnosis or inappropriate treatment have had adverse impacts on their health, quality of life and finances, and implore me to direct them towards a health professional in their area that can help them. Touring the world teaching has provided me with contacts of many health professionals with an interest in the hip, but not nearly enough to provide assistance to the many in need, who are spread far and wide. Hip Pain Help meets that need by providing a vital and growing global directory of ‘Hip Pain Professionals’ and a mechanism for connection with those who are searching for help.

 

We had also identified that there is an incredible amount of misinformation on the internet around hip and pelvic pain, more likely to harm than help those in need. For this reason, we have developed a comprehensive and regularly-updated library of high quality, evidence-informed resources for the general public, accessible in 3 easy ways – Hip Pain Explained, our Pain Locator Map and Specific Condition Pages.

For healthcare practitioners – our Hip Pain Professionals (HPPs), our vision is to develop a multidisciplinary community of health professionals with a special interest in hip and pelvic pain and dysfunction. Here you will find support, inspiration, learning opportunities and helpful resources. Our aim is to facilitate knowledge translation, not only to inform clinicians of current evidence in their field but to cross-pollinate ideas between professional disciplines. There is now much opportunity to engage with other health professionals through social media, but unfortunately many disengage from professional communities in the public realm because of aggressive, disrespectful and unprofessional behaviour of some individuals. Through our closed HPP Facebook group portal, you will find a private environment in which to ask questions freely of the HPP community and engage in respectful conversation on more contentious topics.

 

On this site ( www.dralisongrimaldi.com), you will find a professional blog which will also serve as conversation starters for the HPP Facebook group, as well as information on my upcoming workshops, online learning opportunities, ebooks, and publication updates.

What are you waiting for then?

Development of a successful program for painful gluteal tendinopathy

In my clinical practice I noticed that we were treating many with lateral hip pain, most commonly post-menopausal women. These patients reported pain levels and impacts on their lives as marked as those with hip osteoarthritis. Their sleep and physical activity levels were substantially affected and together with the psychological distress caused by more severe presentations, the impact on general health and quality of life was marked. Long symptom duration, with delayed or mis-diagnosis was frequently reported, sometimes resulting in unnecessary interventions. Those identified as having a local soft tissue pathology had usually been diagnosed with trochanteric bursitis and given a corticosteroid injection (CSI) as the first line medical treatment and bursectomy for those with pain that did not settle. Previous failed physiotherapy had commonly included passive therapies such as therapeutic ultrasound to the ‘inflamed bursa’ and stretches for the iliotibial band or buttock.

Tendinopathy – Does corticosteroid injection aid or hinder our rehabilitation process?

When physiotherapy treatment for tendinopathy fails, have you ever thought ‘Where did I go wrong?’ Assuming you have applied contemporary evidence informed protocols that incorporate load management and appropriate exercise therapy (e.g. avoiding compressive loading for insertional tendinopathies), there are a number of factors that may influence your success, including patient beliefs and compliance, systemic illness and psychosocial issues. Have you ever considered though that prior medical treatment may have had you fighting an uphill battle from the start?

Have you asked a patient to recruit their iliocapsularis recently? Ilio…what?

Yes, this is a real muscle and it may have an important function in joint and capsular protection. There is a rapidly growing evidence base for understanding function and dysfunction of the complex layered muscle synergies around the hip. The development of safe fine wire EMG techniques and reliable dynamic ultrasound imaging around the hip has seen an explosion of research into this fascinating area. We have recent information on deep gluteal and external rotator function, and now for the first time we have fine wire information on normal function of iliocapsularis. Early EMG findings for iliacus and iliocapsularis have been released today in our paper in Gait & Posture1. The landscape in this field is undergoing substantial change and is it important that physiotherapy assessment methods and exercise prescription reflect contemporary understanding in this field.

Are you still prescribing ITB stretches and clams for lateral hip pain?

It might be time for a knowledge update!

Painful tendinopathies are one of the most frequent musculoskeletal conditions with which patients present to physiotherapy clinics. Diagnosis can often be challenging, with hip and pelvic tendinopathies often masquerading as lumbar-referred or hip joint pain. A missed diagnosis or incorrect management plan can lead to delayed outcomes for our patients and loss of confidence & patronage for the physiotherapist. Read more
