Introduction

Gait deviations are likely related to the development of and / or associated with musculoskeletal pain syndromes. It is often the complaint of pain that will lead a patient to physiotherapy. It is the role of the physiotherapist to educate the patient on the aetiology of their pain while treating and correcting the noted gait deviation.

"The kinesiopathologic model was designed specifically to describe the mechanically related processes proposed to contribute to the development and course of low back pain (LBP). The basic premise is that LBP results from the repeated use of direction-specific (flexion, extension, rotation, lateral bending, or a combination of these) stereotypic movement and alignment patterns in the lumbar spine. The model proposes that the patterns begin as the result of adaptations of the musculoskeletal and neural systems due to repeated use of specific movements and alignments during daily activities. The nature and rate of the adaptations can be modified by intrinsic and extrinsic characteristics of the individual, for example, sex, anthropometrics, or typical activities of the person. The typical pattern is one in which, during performance of a movement (eg, forward bending) or assumption of a posture (eg, sitting), the lumbar spine moves into its available range in a specific direction more readily than other joints, such as the knees, hips, or thoracic spine."

Note the interconnected nature of the posterior back, hip, and upper leg musculature.

With the patient's pain as a guide, a goal of musculoskeletal physiotherapy is to identify the anatomical structures associated with the reported pain. Physiotherapists utilise orthopeadic tests to assist in symptom source identification. However, these clinical tests are often inconsistent in their ability to accurately identify the anatomical source of the patient's symptoms. Additionally, there is a poor correlation between imaging results and symptom source identification in the absence of trauma or pathology. These two statements suggest that musculoskeletal pain may often be anatomically and structurally indeterminable. The kinesiopathological approach is an alternative to these more traditional methods of diagnosis. This methods calls for clinical practice to be guided by the identification and modification of kinematic or motor control impairments within a musculoskeletal function. By correcting deviant movement patterns to a more idealised movement pattern unique to a particular individual, subjective pain can be improved and function can be reestablished.

Back Regional Pain

Potential gait deviations associated with LBP:

1. Decreased gait velocity, less than 1-1.4 metres per second
2. Shortened step length
3. Slow gait cadence
4. Stiff counter rotation between the thoracic spine and the lumbar spine
5. Changes in expected vertical oscillation of centre of mass (COM)
6. Loud foot strike
7. Can demonstrate either an increased or decreased pelvic tilt
8. Can demonstrate either increased or decreased hip extension during terminal stance
9. Decrease in big toe dorsiflexion, resulting in a functional hallux limitus

Hip Regional Pain

Region of Pain	Relavent Diagnoses	Expected Gait Deviations
Hip Region	Osteoarthritis Can continue status post total joint replacement	Decreased cadence Shorter step or stride length Increased base of support (BOS) Decreased counter-rotation between the thoracic spine and the lumbar spine Decreased range of motion in the sagittal and frontal plane at the hip Decreased extension particularly in terminal stance Increased toe out Increased lateral trunk lean Increased contralateral pelvic drop Increased lateral shift of COM Late or prolonged heel off Decreased propulsive ankle force
Lateral Hip	Gluteal tendinopathy Piriformis syndrome Complaint of "buttock pain"	Too long a step Contralateral pelvic drop Lateral shift of COM Loud foot strike Decreased daylight or insufficient separation between the knees Foot crossing the midline of the body Oblique popliteal skin crease (excessive medial femoral rotation) Varus or valgus thrust Lateral deviation of the knee during stance phase Increased pronation of the foot
Anterior Hip	Femoroacetabular impingement (FAI) syndrome Acetabular labral tear Status post repair of the acetabular labrum	Unfortunately, the literature on femoroacetabular impingement is somewhat ambiguous Some literature suggests that individuals with an FAI will demonstrate biomechanical differences when ambulating on stairs

Knee Region Pain

Region of Pain	Relavent Diagnoses	Expected Gait Deviations
Knee Region	Osteoarthritis Can continue status post total joint replacement	Increased lateral trunk lean Lateral shift of COM Decreased knee extension during stance phase Increased degree of toe out (more than 10 to 15 degrees from the foot progression line) Demonstrate a varus thrust, lateral deviation of the knee or a valgus thrust (varus thrust is most common)

Back and Upper Leg Region Special Topics

Lumbar Stenosis Gait Deviation

Lumbar stenosis is a common back pain diagnosis in the elderly population. A patient with lumbar stenosis does not stand or ambulate with upright posture, and tend to avoid lumbar extension to decrease and or avoid pain. They may present with a tendency to walk bent over, and lean on their grocery cart or walker. They will likely demonstrate one of two gait deviations to alleviate symptoms associated with lumbar spinal stenosis:

1. 

   Red arrows indicate the ground reaction force vector, blue arrow is the hip flexion moment, and green arc is the psoas major.
   Figure A: Trunk flexion posture with an increased step length and hip extension angle, and an absent lumbar joint moment into extension.
2. Figure B: Trunk upright posture with a decreased step length and hip extension angle and an absent lumbar joint moment into extension.
3. Figure C: Ideal walking posture of healthy people

Dropped Head Syndrome

Black arrows indicate the backward tilted thorax and pelvis. Blue arrows are the ground reaction force vector. Red arrow is the ankle plantarflexion moment.

Dropped head syndrome (DHS) is a relatively rare cervical kyphotic deformity which Chas symptoms of: neck pain, restrictions to ambulation, and impaired horizontal gaze. Due to the interconnected nature of the spine, the relationship between cervical alignment relative to other parts of the spinal column can have an effect on the pelvis and lower limbs during dynamic activities. Patients with DHS demonstrate altered kinematics and kinematics of the lower limbs during walking duet o changes in the inclination of the head and trunk. This may cause deviant gait features and altered motor control compared to healthy individuals. Similar findings have been reported with the use of a smartphone while walking. The increased cervical flexion angle affects: cervical loading, walking speed, and muscle activity of the lower limbs.

1. Figure A represents an individual with DHS: backward leaning posture of the thorax, increased ankle-joint dorsiflexion angle, and relatively shorter stride length.
2. Figure B is ideal walking posture: upright erect posture with decreased ankle dorsiflexion angle allowing for more movement coming from the ankle to propel forward and up.

Geriatric gait

I want to talk for a moment about what would be classified as geriatric gait. They may be in pain or just, just maybe a geriatric gait. The spatiotemporal changes that occur in old folks is they walk slow, less than 1.4 metre per second or one metre per second. They take shorter steps or strides. They have a slower cadence. We've all seen this. In the kinematics, they have a late or a prolonged heel contact. They're going to have a decreased up and down motion, a decreased vertical oscillation of centre of mass, could have decreased hip extension, may have increased forward lean that we saw with lumbar stenosis gait compensation, and they may have decreased arm swing. Often the older people will just walk with their hands held behind their back and not even swing their arms. This is some interesting work by DaVita and colleagues, originally published in 2002. It's talking about the age lower extremity kinematic forces, comparing it between old folks and young folks. So the amount of propulsive force when walking and running varies across the joints in the lower extremity. How much is being propelled forward or up. Old folks, geriatrics, elderly people use hip joint moments more than ankle, whereas young people use the ankle to propel forward, ankle plantarflexion. They use that more than the hip. So if you look at the table, the propulsive force in the elderly is maybe 75%, whereas in the young it's one-third, roughly speaking, whereas down at the ankle, old folks only use the ankle to propel forward by 12%, a very small amount. So I think this is an interesting thing that we can take advantage of when we get into gait training and intervention with our old folks that are increased risk for falling or having pain, we can get them to use their ankle more. So this graph is the AP force, the fore-aft force that occurs during stance phase. So the horizontal axis is just stance phase, the vertical axis is the force that's the brake or the propel forward, the fore and aft that occurs. And there's in the first half of the first period of stance, there's a negative braking force stopping you from going forward and in the second half from midfoot to forefoot rocker or terminal stance, that's when you propel forward, also propelling up. So DeVita and colleagues did some, they were able to amplify and augment this and provide feedback to a group of normal subjects, trying to get them to increase that propulsive force with an instrumented treadmill and the camera right in front of the treadmill. And they said, we want you to increase that, increase it. And both the old people and the young people were able to increase the total lower extremity propulsive force given that feedback. That was real-time feedback. But what they discovered was both the old people and the young people, to generate that increased force to get it above the threshold, both the young and the old used their hip. They didn't use the ankle. So they did a follow-up study where they gave the feedback and just look at ankle joint plantarflexion external moment and they were able to, with augmented feedback, increase the propulsive force coming from the ankle joint. We don't have in our clinic, these augmented feedbacks, instrumented treadmills, and sophisticated equipment, but what I take from this is when we give a verbal cue, not that I want you to push more, I want you to propel up, leave an imprint from your foot, move from your ankle. Again, we're going to talk about internal cueing and external cueing. Basically the soundbite that I use is I want you to walk with spring in your step. That's going to get you to use the ankle if the gait deviation is decreased vertical oscillation of centre of mass or prolonged heel contact.

Osteoarthritis and Total Joint Replacements

Next region of pain I want to talk about is hip pain, osteoarthritic pain and the gait deviations that can continue status post total hip joint replacement. Oftentimes patient with hip osteoarthritis develops gait deviations and has a habit and even when they have a normal joint, they may continue to walk with that habit, that deviated habit. The next pain syndrome I want to touch on is knee pain associated with osteoarthritis and/or again status post total knee joint replacement, that gait deviations may continue.
