Physical Therapy Management of the Hypermobile Patient

Terry Olson, PT, MHS, FAAOMPT, received his physical therapy training at the University of Iowa and he has an interest in the manual treatment of the muscular skeletal problems. He subsequently received his Masters Degree in orthopedic physical therapy and he developed a post graduate program in exercise and manipulative therapy. Mr. Olson is a fellow of the American Academy of the Orthopedic Manual Therapists and we would like you to welcome Mr. Terry Olson.

I am going to present this from the standpoint of looking at hypermobility. We are going to look at a definition of hypermobility, its relationship to EDS, then talk about the role of exercise and joint protection, and a short case study that I thought I would present.

Okay, what is hypermobility? There are quite a few definitions, but the one that seemed to be the simplest was that it is a connective tissue disease, where connective tissue proteins, such as collagen, which give the bodies its intrinsic toughness, are differently formed; the results are mainly felt in the moving parts, that being the muscles, joints, tendons, ligaments, which now are more fragile than is the case for most people. The result is joint laxity with hypermobility and with it comes vulnerability to the effects of injury. The young girl presented here is the one on which I did the case presentation.

Quick review of the categories.

*
Classical: Looking at skin hyperextensibility, tissue fragility and joint hypermobility.
*
Hypermobility: again, joint hypermobility is the dominant characteristic, may have joint subluxation and dislocation, limb and joint pain.
*
Kyphoscoliosis: generalized joint laxity and severe muscle hypotonia, scoliosis, tissue and organ fragility.
*
Arthrochalasia: congenital hip dislocation, severe generalized joint hypermobility, recurrent subluxations, tissue fragility, and muscle hypotonia.
*
Vascular: organ fragility with the possibility of arterial or organ rupture, tendon or muscle rupture, joint hypermobility primarily in the digits.
*
Dermatosparaxis: severe skin rigidity, skin soft and doughy and may have large hernias.

Of all of those categories, the dominant feature from a physical therapy perspective is hypermobility and joint laxity, so those are the primary considerations for a therapist when treating patients with EDS; and that means that treatment needs to focus on joint protection and dynamic stabilization of those joint structures.

Muscle stiffness is a term that is used to describe the spring-like quality of muscle. When a muscle has high stiffness, increased force is required to cause lengthening of that muscle or to perturb it. Muscle stiffness has been described in the biomechanical and neurophysiological literature as one of the most crucial variables in joint stabilization; and in the knee a link has been established between receptors in the ligaments of the joint and muscle stiffness. The slide includes a few of the references for that.

In the residency process (I went through post-graduate residency training in manipulative and manual therapy) you are primarily moving joints that are stiff. Switching to talking about joints that are not stiff, which is the case here, takes a bit of a shift. One of the things taught in the residency process was that you cannot distinguish a problem as being a joint problem or a muscle problem. The structures are so closely interrelated that the feedback between the two is critical to the integrity of that joint. If you have problems within the joint; because the joint provides feedback to the muscles, you are going to have muscular weakness. If you have muscle weakness, again through association with the joint structure, you are going to have impact on the stability of the joint. Thus, any treatment needs to be directed at all of those structures.

It is possible that the sensory properties of structures within joints can be modified by the contraction of the local, stabilizing muscles, and this is usually the proximal muscle groups. If you are looking at the shoulder, you are talking about the scapular cervico-thoracic muscles and the large shoulder muscles themselves. If you are talking about ankles and knees, you are looking at the muscles in the trunk and the pelvic girdle.

Besides providing mechanical stability to the joints, these muscles can contribute to the sensory feedback mechanisms associated in the joint structures themselves. A study done by Blazier, Carpenter, and Houston showed that tightening of the joint structures with active muscle contraction increases the acuity of that shoulder joint. That means if the muscles are functioning properly, then they are going to provide feedback to the joint which, in turn, makes a more stable situation for that joint and the joint has the ability to have feedback as to where it should be positioned.

Dynamic stabilization, or the use of exercise to promote joint stabilization, occurs when tonic (postural and slow twitch muscle units), are activated. These tonic motor units are activated during tonic continuous low load activation of muscle, maximizing muscle stiffness. What we are talking about here is asking the muscle to contract gently, not maximally, and to be able to sustain that contraction for a period of time. This can be influenced by the speed of the activity or exercise, as well as the type of muscle contraction you are trying to acquire. Muscle contractions that are performed in the shortened range of the muscle length are going to be critical in establishing the sensitivity and optimal functional capacity of the sensory feedback system in the muscle.

All that says is that when you are exercising - for folks that are afraid to exercise, for folks that have an inherent increase in mobility - exercise needs to be done in a very small controlled range of motion. Dr. Unger and I have had discussions about patients that we might see commonly as well as the patients I have seen from Dr. Mark LaVallee. One of the things that I have seen somewhat consistently is that the patients who are stretching don't need to stretch. They will tell me about being stiff and they will take their leg and wrap it around their head and it is just difficult to relate to that as being stiff. Now you can have a feeling of stiffness, if the muscles are fatigued or overworked, which to me then relates back to weakness.

Co-contraction and co-activation of muscle groups provides the biomechanical forces for joint stabilizing and protection, especially if they are performed in mid-range or neutral joint positions. Every joint, in its ability to move through range, is going to have positions that are inherently more stable because you have joint surfaces that have better contact with each other. You also have a point in that range where the muscle has mechanical advantage. If I am bending my elbow, the biceps will do that. When the bicep is in its lengthened range (elbow fully straight), I am going to be much weaker than when I get to a point (elbow fully bent) when things are going to shorten or come closer together. Mechanically this is much stronger. And, so, when you exercise EDS patients, you need to make sure you attend to placing them in those mechanically advantaged positions to work and exercise.

This is not just with EDS, but with many of the patients I see that have weakness or hypermobility. They do not exercise their full range of motion, they do not have the control to do so, and building the ability to exercise to the greater range is the goal. So, you start where the patient can perform in a pain-free and stable manner. Closed chain exercise is superior for muscle protection of the joint, although open chain exercise is also beneficial and necessary, especially again if it is performed in the protected range of motion.

When we are talking about open chain exercise/closed chain exercise we mean the following. Open Chain Exercise: if I want to exercise my quadriceps, that is the muscle that straightens my knee out, that is open chain, just moving my leg through range of motion. Closed Chain Exercise: if I stand here and do a squat, I am still working that quadriceps muscle, but by virtue of contact with the floor, we now have other muscles that act to provide increased stability. So a lot of times, starting these patients with exercises that are more closed chain, enhances that ability to stabilize muscles around the joint.

Case presentation

We take a body chart that the patient marks when they come in - and again, typically, when I get a body chart on a patient from Dr. LaVallee, that whole body chart may be colored in - it looks like they have a suit on.

As a therapist, where do you start with that - you cannot treat everything. In this case here, the young girl, the primary complaint was the mid lower back, and the other complaints were part of her overall problem; but in this case not the primary reason for presenting to therapy. Primarily, it was because of back and hip trouble. She had a diagnosis of lumbar back pain, left hip pain, and EDS multiple areas of pain complaint and again those were most notable in back and hip. She described pain complaints of an 8 out of 0-10, (0 being no pain, 10 being like a wild animal tearing your leg off).

She described her pain at her worst as being an 8 on that scale with standing for more than one hour being a provocative activity, as well as her activities of daily living. One of the things that were important at that time was that she had a baby, and that holding her baby was enough to provoke a lot of these pain complaints. She had objective signs of multiple joint hypermobility with back pain reproduction.

In her case, initial emphasis was on symptom alleviation using modalities (heat and cold, TENS units, electrical stimuli), gentle joint mobilizationand biomechanical correction, as well as performing assisted exercise in protected asymptomatic range of motion. We also provided biomechanic counseling on joint protection, as well as back care education regarding lifting, sitting, and performance of her activities of daily living.

Over the course of treatment, as her symptoms decreased, we progressed into more dynamic exercise, dynamic stabilization, and that become the crux of her home program.

One of the things that we can use in the setting that I work in, at least in the acute phases, is equipment designed to start exercising folks at less than full limb loading. If you have someone that has an injury or problems with - as in this case - knee and hip, and those problems occur when they are weight bearing, then the idea is that exercise has value because if we exercise, we have the ability to increase blood flow and circulation, increase oxygen, all of the things that are essential for healing, as well as building blocks for laying down stronger tissue. The problem is bringing that load to an acceptable level for that person.

So, in this case, this patient is just doing a bilateral squat activity and the slide board allows her/him to exercise anywhere from less than 20% of body weight taking it all the way up to 70% of body weight and then we know how to graduate that into a gym exercise. We try to exercise people as functional as we can, so if people have complaints of “when I stand too long or when I walk too long, when I bend is when I have my complaints,� I am going to try to set my exercise program up so that they are standing, walking, bending, but using the equipment to again decrease gravity, or their body weight, so that they are exercising with less body weight on those joints.

In this case, with walking, we use a treadmill system that has an overhead pneumatic assist and that harness allows us to hoist someone up. We can take that person, take as much as 70% of body weight (essentially the weight of the trunk - you go any higher than that and you are like Peter Pan and you are unstable, and you are ready to fly) then you are still getting input into the joints, but not full load.

I had a discussion with one of the participants who asked me about Pilates - I am going to beat people to the punch - I don't know. Pilates makes sense to me that it can be of value, but I don't know enough about it and I might make an idiot of myself trying to tell you the value of it.

Not for purpose of this talk, but if it gives any rationale to why; the approach that we use is a system called "medical exercise training". That approach is based on specific tissue exercise, and so we work from a standpoint that muscle requires a different muscle stimulus than does tendon, than does cartilage, than does disc. All of those structures have a different metabolic requirement, so those exercises have to be different, and when you are working with folks who have tendonitis, we try to work out an exercise program that allows that person to go through anywhere from 150 to 200 repetitions - because that seems to be the adequate number of repetitions to get an adequate increased blood flow to the area to promote a healing response. When trying to address structures such as ligament, cartilage, disc, those structures require upwards of 1,000 to 1,500 reps. The problem is taking someone who hurts and tell them you are going to put them on an exercise program of 1,500 repetitions and then say I will come back in an hour and see how you are doing. So to do that, you need to take load off, and the purpose of the equipment is to assist that part so that person can perform repetitions without pain. And then as the structure begins to heal, we gradually put load back on.

So this was the initial phase. In addition, we started to work on trunk. With Pilates or with other approaches, their value is core strengthening of the trunk - because your arms and legs attach to your trunk and if your trunk is not stable, then it is difficult to promote stability into those joints. Oftentimes the trunk is the most logical place to start, and is probably the easiest because everything else has to function off of it.

A simple leg raise will require activation of the transverse abdominal muscles if they are activated and used. The fact that her back is arched and she is unable to keep it from arching is indicative of the fact that a good exercise becomes a very poor one because she doesn't exhibit the ability to recruit enough trunk muscles to actually handle the weight. Here, she is able to keep the trunk stable (you don't see that hollow) and so she is performing that exercise actually really well with good trunk control.

Exercise is controlled trauma. When we exercise someone, we are inflicting trauma - the idea is to control it. If you exercise adequately, you are going to break down tissue, then let it rest and in this phase it recovers and lays down stronger tissue - if you adequately stress it. If you overstress it, then a good exercise becomes a bad exercise pretty quickly. All day long I see patients come in who are failures at exercise programs and it is not because exercise is not a benefit to them, they have just not been trained to do it with good form and to work in a range where they have control. You need to understand what is safe.

I had actually treated Erika about 9 months ago and she did well. I asked her to come back to see how she was doing but also to take some photos for this presentation and it was a good chance to take her upstairs and see if she was doing what we had instructed her to do 9 months ago. She demonstrates incredible form. Her elbows are going the wrong way and you would think that would make sense, but when we first went over her exercises and she did things, a lot of the things she was performing, a lot of work was in an unstable range and it was causing a lot of pain. It was just a matter of again making certain that her trunk was active and then worked in the range that she could exhibit control.

The exercise doesn't matter - when I set exercises for people, it doesn't matter, pushing up, pulling down, pushing away, pulling into them, I do a variety because life is made up of that. You need to be able to do all sorts of things but in a stable manner. The exercises need to be changed and modified as long as the patient understands stabilizing well, good trunk improvement, and that the joints are working in a range where they were stable.

I saw Erika for 9 visits over a 5 week period. Initial treatments consisted of gentle treatment to relieve symptoms coupled with assisted exercise utilizing the assisted treadmill walking and total gym. The patient then progressed to a stabilization and progressive strengthening exercise program. Her symptoms decreased, her discharge pain complaints were decreased, and she was able to stand and sit for more than two hours without symptoms, as well as lift her baby without increase in symptoms.

The final slide provides some excellent overall points in your therapy process. All of these things can be used in treatment and pain reduction. What I have seen with pain reduction, if you are heating people or icing them or electric stimuli, you are doing things that are temporary. Long lasting change is only going to come with making a change in the body, to the extent that you can. So, exercise with emphasis on controlled range of motion or working within a range of control. Pool therapy is beneficial and we use a pool at our facility also. Pool therapy takes the body weight off much the way the harness mentioned above does. Massage certainly has value, but again I think you need to be careful about monitoring skin integrity, especially if you are doing friction massage which is one of the therapy modalities often used in treating tendonitis. Use of splints or bracing - those are done supportively. Annual therapy, manipulative therapy, chiropractic therapy - it is not contraindicated, but you need to make sure you are addressing treatment to a joint that needs to be moved, not the joints that already move excessively. As a general rule, you want to be cautious of vigorous stretching secondary to inherent hypermobility. Again, I don't teach people to stretch, but they do need to strengthen because they have all of this range of motion that they don't have control of and that is painful. A lot of patient education, regarding ergonomics, joint protection, body mechanics, is required.

a Friday funny

I had to ring UHC today to follow up with more claims as their process is so insane it takes time every day to make sure everything is being taken care of on their end, by me. I think I should get a paycheck from them. Anyway, whilst I was on the phone I asked the rep about this "30 day Physical therapy" bit they have listed. My PT and I have had to rush as much as we can so we do not use up all of my 30 visits as that's all that is covered for the year. NOT per body part or problem, but in total. I was shocked to learn that. I had thought it was per problem, as that is what it was on my previous insurance.

Here's the funny part, she said that it's only for 30 visits so "the therapist can't lie to you and tell you you're not improving and tells you to keep coming back so they can keep getting paid". HA! More like UHC trying to save money and neglect patients that really need the coverage!

I explained to her that one can usually tell when one is improving or not, and what happens if you G-d forbid have an accident or something goes wrong with another part of your body - and you need PT? She said that you can always write to UHC BEFORE the 30 visits are finished and they will review the case, and you should send in medical histories and a note from the doctor saying why it's medically necessary. I tried not to laugh out loud - as those of us who have tried this after being cut off know there is a minimal chance of you ever getting those additional visits you need. I did mention to her that I found it strange that the insurance companies put weird restrictions on recovery times for specific problems, like if you're in PT for your neck, you should be better within 6-8 weeks, or something along those lines. She actually agreed, but she's also just a rep and doesn't have any control. Still, I had to mention how absurd it is to assume each persons body is exactly like the next persons as it just doesn't work that way.

I truly hate insurance companies................

There are six major types of EDS. The different types of EDS are classified according to the signs and symptoms that are manifested. Each type of EDS is a distinct disorder that "runs true" in a family. This means that an individual with Vascular Type EDS will not have a child with Classical Type EDS. More detailed information can be found in our Medical Professionals Section.

General Frequently Asked Questions
Hypermobility (Formerly EDS Type III)

Joint hypermobility is the dominant clinical manifestation. Generalized joint hypermobility that affects large (elbows, knees)and small (fingers and toes) joints is evident in the Hypermobility Type. Recurring joint subluxations and dislocations are common occurrences. Certain joints, such as the shoulder, patella, and temporomandibular joint dislocate frequently. The skin involvement (hyperextensibility and/or smooth velvety skin) as well as bruising tendencies in the Hypermobility Type are present but variable in severity.

Chronic joint and limb pain is a common complaint amongst individuals with the Hypermobility Type. Skeletal X-rays are normal. Musculoskeletal pain is early onset, chronic and may be debilitating. The anatomical distribution is wide and tender points can sometimes be elicited.

To date, no distinctive biochemical collagen finding has been identified by researchers. The Hypermobility Type of EDS is inherited in an autosomal dominant manner.

(from EDS National Foundation site)

What is EDS?
Individuals with EDS have a defect in their connective tissue, the tissue that provides support to many body parts such as the skin, muscles and ligaments. The fragile skin and unstable joints found in EDS are the result of faulty collagen. Collagen is a protein, which acts as a "glue" in the body, adding strength and elasticity to connective tissue.

Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable connective tissue disorders, characterized by articular (joint) hypermobility, skin extensibility and tissue fragility. There are six major types of EDS. The different types of EDS are classified according to their manifestations of signs and symptoms. Each type of EDS is a distinct disorder that "runs true" in a family. This means that an individual with Vascular Type EDS will not have a child with Classical Type EDS.

What are the symptoms of EDS?
Clinical manifestations of EDS are most often joint and skin related and may include:

Joints: joint hypermobility; loose/unstable joints which are prone to frequent dislocations and/or subluxations; joint pain; hyperextensible joints (they move beyond the joint's normal range); early onset of osteoarthritis.

Skin: soft velvetâ-like skin; variable skin hyper-extensibility; fragile skin that tears or bruises easily (bruising may be severe); severe scarring; slow and poor wound healing; development of molluscoid pseudo tumors (fleshy lesions associated with scars over pressure areas).

Miscellaneous/Less Common: chronic, early onset, debilitating musculoskeletal pain (usually associated with the Hypermobility Type); arterial/intestinal/uterine fragility or rupture (usually associated with the Vascular Type); Scoliosis at birth and scleral fragility (associated with the Kyphoscoliosis Type); poor muscle tone (associated with the Arthrochalasia Type); mitral valve prolapse; and gum disease.
What are the types of EDS?
There are six major types of EDS. The different types of EDS are classified according to the signs and symptoms that are manifested. Each type of EDS is a distinct disorder that "runs true" in a family. An individual with Vascular Type EDS will not have a child with Classical Type EDS. Learn more about the different types of EDS.
How is EDS diagnosed?

The categorization of the Ehlers-Danlos syndromes began in the late 1960's and was formalized in the Berlin nosology. Over time, it became apparent that the diagnostic criteria established and published in 1988 did not discriminate adequately between the different types of the Ehlers-Danlos syndrome or between the Ehlers-Danlos syndrome and other phenotypically related conditions. Learn more about the EDS nosology and how EDS is diagnosed.
How prevalent is EDS?
At this time, research statistics of EDS show the prevalence as 1 in 5,000. It is known to affect both males and females of all racial and ethnic backgrounds.
How is EDS inherited?
The two known inheritance patterns for EDS include autosomal dominant and autosomal recessive. Specifics regarding genetic inheritance may be found by following the link below. Regardless of the inheritance pattern, we have no choice in which genes we pass on to our children. Read more about hereditary patterns.
What is the prognosis of someone with EDS?
The prognosis of EDS depends on the specific type. Life expectancy can be shortened with the Vascular Type of EDS due to the possibility of organ and vessel rupture. Life expectancy is usually not affected in the other types.
What can I do now?
The defining trait of those affected by EDS is the search for information. The rise in Internet usage in the last few years has delivered a significant benefit to families affected by EDS. EDNF members are sharing information on-line and learning from each other in ways that were impossible a decade ago. Learn more about the benefits of EDNF membership.

Ehlers-Danlos Syndrome

• Ehlers-Danlos (pronounced A-lerz-DAN-los) Syndrome, an inherited disease, is a defect in the connective tissue that supports many body parts, including muscles, tendons, ligaments and skin.

• The fibrous protein collagen is faulty, causing connective tissue to not be elastic or strong. Collagen acts as glue in the body, adding strength and elasticity to connective tissue.

• There are six major types of Ehlers-Danlos and symptoms depend on the type. Symptoms include loose, unstable joints and skin that bruises or tears easily.

• The syndrome may be diagnosed with a skin biopsy, a physical exam and a review of family and medical history.

• There is no cure. Treatment options vary and include joint protection, surgery to correct fractures or dislocated joints, pain management and having a strong support network.

• Sources don’t agree on the prevalence of the uncommon syndrome.

• People with Ehlers-Danlos generally have a normal life span. The syndrome does not affect intelligence but physical activity often is restricted.
