How return to running can begin in acute injury rehab

An article for Inform Performance E-Magazine. (Includes brief videos for visual aid, around 1 min long).

Return to running is often discussed in sports rehab and we are getting spoilt with the metrics and objective measures that we can use now to help inform return to running. But what comes before this stage? Before we start achieving jump heights or reactive strength index scores, or even before that with endurance capacity tests like calf raises? There is often a quiet period of rehab, the rarely spoken, often ignored doldrums of acute injury. Priority is rightly focused on pain, range and swelling. But, we usually have a lot of time on our hands with athletes who are used to being busy and who like to move. Speaking from experience in football, a sport where running is vital to performance, fit players don’t often have time to work on their running because they are too busy training or recovering. Especially in youth sport, we can grab some much-needed time with athletes to work on running skills as part of their return to train.

I want to share some ideas and concepts that I have professionally borrowed (sounds better than stolen) that influence a lot of my rehab programs and pay forward when it comes to returning to running later down the line. I’m not going to discuss any particular injury, I’m going to leave that to you to work around with your own clinical reasoning. With that in mind, the order of these interventions will change depending on what tissues you are offloading. With most things that I share, these are concepts and not hard & fast rules.

Return to running

To be clear, I am not a sprint coach, but I want to demonstrate how we can bridge the gap from acute injury to some basic running drills. The main ones I want you to think about are the A-drills and wall drill variations that encourage triple flexion and triple extension.

So, regardless of the injury, we have some key goals that we can work towards in acute rehab (delete as appropriate to your injury):

  • Plantarflexion of the ankle & Dorsiflexion of the ankle
  • Full knee extension & mid / inner range knee flexion
  • Hip extension & inner range hip flexion

I would argue that is not teaching anyone anything new. But part of rehab is to regress some of the demands and build back up. So let’s think about some of the contributing factors that will form the foundations of those movements and then using the rehabilitation progression model that Phil Glasgow and I published in 2017, demonstrate how they interact and develop into something that starts to look like running.

Break it down to build it back up

A big win for me in most rehabs is addressing the coordination and interaction around the femur, the pelvis and the trunk. Firstly, the ability to independently move one segment, in order to focus proprioception, before building to more complex movements that involve multi-segmental coordination. The ability to switch between isolated and involved movements, or your brains ability to handle that information, being called “dissociation”. Rehab is an opportunity to allow these movements to be conscious, with high repetitions, encouraging them therefore to become subconscious and more automated on a return to sport.

Femur & pelvis

This could be a massive discussion as we look at all the variations of how the femur interacts with the pelvis during movement. But let’s go back to thinking about those A-drills. Flexion and extension of the hip should be straight forward. But what about the role of pelvic tilt during that flexion and extension?

Anterior-posterior tilt exercises:

And not just anterior to posterior, but often the importance of lateral pelvic tilt is ignored.

Lateral tilt? In sprinting? Surely that’s a big energy leak… well.. yes and no. This is different to a hip hitch, which can be a passive movement and demonstrate a lack of control. We can build up awareness of a lateral tilt and learn how to resist against it but also, there is possibly an element of hip extension during running that gets forgotten. The active distraction of the femur from the pelvis.

Hip distraction and lateral tilt exercises:

Indulge me for a second whilst we talk anatomy.


Don’t worry, I’m not going to ask if you think you can palpate it or not.

Traditionally the iliopsoas (the combined tendon of the broad, flat iliacus muscle and longer thicker psoas muscle) has been considered a conjoint tendon. Recent anatomical studies have started to debate this, with potentially two distinct tendons. There is anatomical variance, what was previously discussed as a rare variant, it is now believed that the majority of cases demonstrate >2 tendons (Polster et al 2008; Guillin et al 2009; Philippon et al 2014). Furthermore, in the cases of more than one tendon, the isolated psoas tendon is significantly thicker than the accessory iliacus tendon. This is of interest in a rehab setting.

The purpose of these studies is mostly surgical, research into the roles of the two tendons in function is not as strong. However, Suzanne Scott (one of my go-to resources for movement and anatomy) believes that the thickened tendon demonstrates a role beyond simple hip flexion, instead acting in much the same way as an Achilles tendon in energy storage. The spring of the hip.

To load this spring, we have two methods:

  1. Distraction of the hip
  2. Extension.

In both cases, we need to create active stiffness, so this is where our dissociation comes into play. In these examples, we are looking to keep the trunk stiff whilst we load and release through the hip. (Ensuring that trunk mobility and control is addressed elsewhere in the program).

This in turn benefits our ability to “snap” into hip flexion. Adding tension into extension to spring into flexion, with consistent cues around “push the floor away” or “drive into the floor”.

With any inner range, we are inefficient in contraction ability and strength (due to shortened actin-myosin cross bridge formations), we also have the issue over space in the anterior joint, so working into strength positions in this range along with pelvic control, is going benefit that spring later on. From this inner range position, we have a greater ability to drive down into the floor as we start the reloading process of the spring all over again.

Loading the spring:

Inner range hip strength:

If we are looking to load that spring when running, I’m thinking here about the foot strike and push off from the ground, then this spring needs a solid frame built around it in order to maximise that energy storage. So, whilst maintain trunk stiffness and exploring lateral tilt of the pelvis, we can also look to resist against it. Our biggest ally in this is the gluteus medius. Where possible, I believe the lateral hip should be loaded as much as possible in a closed chain. I think exercises like “clams” are poorly prescribed and the rational is often flawed. This is why.

Gluteus medius

Gluteus Medius strength and function is an important consideration to running due to the role in coronal plane stability of the pelvis during the stance phase of running. It is another muscle that is grouped together and treated as a singularity, when in fact, morphologically the muscle has three distinct parts, anterior, middle and posterior, each varying in size and demonstrating separate innervation for each part (Al-Hayani, 2009). The direction of the fibres of the anterior and middle parts of the gluteus medius (and the anterior part of the gluteus minimus) suggests that they have vertical pull and initiate (key word) abduction, which is then completed by the tensor fasciae latae.

The middle and anterior gluteus medius is relatively large in cross-sectional area, has a large abduction moment arm and has fascicles that are aligned relatively vertical in the coronal plane (Flack et al 2014). On a fixed lower limb, these morphological characteristics are ideal for generating the large torques required to absorb the vertical ground reaction forces imposed on the body and to support coronal plane pelvic alignment during the early stance phase of running (Semciw 2016).

EMG analysis of gluteus medius during running was typically presented as mono-phasic, with peak activity occurring just after initial contact (Semciw 2016). One study presented a bi-phasic pattern, with a second, smaller burst of activity occurring at toe-off (Gazendam et al., 2007).

So, whilst they initiate abduction, they play a bigger role in the stance phase of walking and running. Therefore, I more interested in their role of pelvic stability. Lets flip that abduction movement around and fix the femur, the movement now begins to look more like a lateral tilt, a much smaller movement through range than abduction but one that will benefit our foot strike and our psoas spring.

Glute med exercises:

“Coming together is the beginning, working together is success”

So, at differing stages depending on the injury, we have worked individually on pelvic movement, lateral hip contraction, loading the hip flexors as a spring via distraction and also in the inner range, we have encouraged active trunk stiffness throughout to support these processes. As the rehab progresses, it becomes important to move away from isolation and look to combine these drills to increase complexity and transition back to running.

Figure 1: Blanchard & Glasgow 2017 rehab progression model

The options with each progression become greater and depend on your clinical reasoning skills to add variables. The next two suggestions are very basic exercises to demonstrate that progression.

Dead bug:

There are many variations of a “dead bug” exercise but one for me that really translates into what we are trying to achieve from a running perspective. One that combines inner range hip strength, active trunk stiffness, hip extension and distraction and all mixed together into a complex dissociation exercise. A simple, low load drill that can be added to most programs either at the beginning as a familiarisation pattern or at the end to work control under fatigue.

Dead bug:

Hurdle step over:

From what I’ve seen, most sports will build in hurdle drills to some form of gym or warm up session. But how well is it coached? What is the aim and rationale? How passive do most athletes look when they are stepping over hurdles, honestly?

Some typical “cheating” movements I look out for in hurdle drills mostly involve flexion where its not wanted. When an athlete is lacking inner range hip flexion strength or control for example, they will flex at the trunk and drop into anterior pelvic tilt as they try to “pull” the femur closer to the body to clear a hurdle.

This is quite commonly combined with a passive flexion of the standing knee, relaxing the proximal portion of the quads to allow this movement. What benefit does this serve? I guess this depends on why the hurdle step overs have been prescribed in the first place, but if its to act as a constraint and encourage good hip mobility, good active hip mobility, in prep for running, then this cheat makes it a waste of time.

Figure 1: Blanchard & Glasgow rehabilitation program (2017)

Using our regressed exercises from above, we have hopefully provided the coordination, control and strength to perform this movement with more purpose. So, focusing on a triple extension of the standing leg, getting terminal knee extension, “pushing the floor away” or “leaving a footprint on the floor” we should also get the hip distraction, loading the spring. In turn, this cueing of the standing leg should therefore transfer into a quick, active “snap” into posterior tilt, clearing space in the anterior hip of the flexed leg and all done with a strong, stiff trunk.. looking much like our A-drills. 

Hurdle drills:

On you go..

The list of exercise potential is endless, so many variations and constraints that can be added or tweaked. Most people will have their go-to list of drills that achieve exactly what I have explained here. The purpose of this piece today was to add some depth to the acute stages of injury, where we are often left wanting and adding time fillers to the program. Hopefully this has sparked some ideas or direction to where you could go with running drills even in the early days of injury. As the great Phil Glasgow says, “Rehab is training in the presence of injury” and if you can use the time to strip back complex drills knowing that the repetition and coordination will be useful on return to sport, then try and maximise your time and optimally load at every opportunity.
