Connective Tissue. I'm sure we've all heard this term.
It’s tissue that, well, connects. For example, your blood is the most available connective tissue in the body. It connects every tissue in the body.
Fascia is also one of the most wide spread connective tissues. Fascia is relatively the same no matter where in the body you find it- such as around your fat cells, adhering them to your skin. Or in your abdomen holding your organs in place.
For this article's purpose, we're talking specifically about myofascia- muscle fascia.
Muscle Design
To understand the purpose of fascia, we must first understand how a muscle is designed.
A muscle is composed of mostly 2 main parts: the muscle belly (fibers that shorten and lengthen), and the tendon (the ends of the muscle belly that are dense, strong fibers anchoring the muscle to the bone)
A muscle belly works through a collection of many muscle fibers that contract- shorten to pull a joint. Those fibers also lengthen to allow a joint to move in the opposing direction.
If you touch your nose, one of the muscles shortening to perform this action is the bicep. When you raise your arm to touch your nose most of the fibers of the bicep work together to shorten and pull the elbow into flexion. Then, to put your arm back down, the shortened bicep has to lengthen for your elbow to move into extension.
Without fascia wrapping around each part of the muscle, muscle fibers would be loose, independent moving fibers in the muscle belly, and would only be gathered at the ends, where the belly turns to tendon.
Imagine 100 elastic chords gathered at both ends. If you were to move the 2 ends closer together and pull them away, the bands would not stay in sync with each other. Each band would move rather independently. Now, if you were to apply an elastic adhesive to each of those bands, grouping them together but still allowing flexible movement, when you bring the two ends towards and away from each other, each band would then be moving alongside the others, as a collective cohesive group. This is what fascia does for muscle fibers. Fascia is strong, semi elastic tissue that covers each layer of a muscle, keeping all the moving parts working together.
If we dive into a muscle layer by layer we see how integral fascia is:
The outermost layer of each muscle is fascia surrounding the belly and tendon.
The muscle belly itself is then wrapped in a layer of fascia.
>The belly is comprised of many muscle fascicles.
> Each muscle fascicle is wrapped in fascia
> Inside each fascicle are many muscle fibers.
>Each muscle fiber is wrapped in fascia
Fascia is the glue that holds all these moving parts together, layer by layer.

Fascia Dysfunction
Fascia is an integral part of muscle makeup. However, it can also be the root of some problems too.
If you're experienced with massage therapy, muscle pain or have been reading some of my content, you at least know of the word "trigger point". Yep, thats rooted in fascia dysfunction. Have you ever rubbed your skin and it feels gravely or crunchy? Yep, that's fascia "adhesion" too.
Back when I was in school they said we would "know it's fascia when it feels like bubble wrap or rice crispies under the skin". Superficial fascia restrictions can feel like this as fascia lays in sheets, like plastic wrap. It's strong and a bit clingy, capable of shortening, wrinkling and adhering different muscle fibers, skin, and fat to one another.
Trigger Point and Muscle Dysfunction
The center of a muscle "knot" is often held together by shortened fascia.
Muscle tissue takes orders from the brain. The brain says were going to itch our nose, and the muscles say "yes captain, moving towards the target at this speed and velocity". The brains and muscles are in constant relay to make sure we lightly itch our nose and not smack ourselves in the face.
However, if we itch our nose and never lengthen our arm back out, after a while (we're talking weeks to months) those muscles would adopt that behavior as "normal" and that will become the status pro quo. The muscle would become incapable of behavior outside it's current range of use. As your muscle stays short, the fascia will also shorten and gather, adhering to itself and any surrounding tissues.
As muscles take orders from the brain. You would be able to train these muscles to lengthen back out again, and slowly over time, would be able to develop different behaviors and capabilities. Fascia however, doesn't take orders. It simply goes with the muscle and joint movement. It is possible for fascia can act as a restrictive force, pulling on different layers of a muscle and holding it to a shortened position.
Now many would ask "wouldnt lengthening the muscle eventually lengthen the fascia out?".
Yes... and no.
Broad and more superficial sheets of fascia will most likely stretch and gain length as your muscle and joint develop the capability. It is very likely, though, to have some remaining sections of shortened fascia throughout each muscle belly, adhering segments of muscle fibers together- making trigger points or "knots" in the muscle.
Although you may get the majority of fascia to lengthen, it can still cause tension through your chain of movement. More superficial sheets of fascia are widespread, such as a plane of fascia that reaches from the jaw, down the neck, through the chest and down the arm to the fingers. I've heard from many patients, not realizing how much fascia was creating tension patterns, comment on how loose and "free" they feel after solely treating fascia restriction.
As a therapist, treating common restrictive fascia patterns is one of the first points in session for anyone dealing with tight aching muscles, postural complaints or movement dysfunction.
How's your fascia doing?
Contributing Factors to Fascia Dysfuntion
Patients often ask me "what causes this" fascia issue. I jokingly tell them "everything". So here's the semi-official list:
- age
- dehydration
- repetitive motions (like hammering)
- serious lack of movement or exercise
- poor posture
- sitting in awkward positions for long periods
- muscle weakness
- working in or living in a cold environment or intensely cooling muscles like sleeping in front of an air conditioner
- emotional stress
- nerve impingement or compression
- metabolic or hormonal issues like thyroid disease or diabetes neuropathy
- nutritional and vitamin deficiencies, including vitamin D and folate
- chronic infections
- any injury to the musculoskeletal system or intervertebral disks
- generalized fatigue
- lack of sleep
- hormonal changes such as menopause
- other pain or inflammation conditions
- obesity
- smoking
So, now that we know that just about anything can cause fascia dysfunction. How do we fix it?
Therapies
- Massage therapy including trigger point treatment, scraping, cupping, passive stretching, pin and stretch, fascia winding, flossing
- Physical Therapy for supportive strength and improved mobility
- Dry needling
- Spray and stretch
- Ultrasound therapy
Home Remedies
- Choose a better chair at work and improve your posture.
- Try a new mattress, or adjust your sleeping position.
- Practice yoga, Pilates, or another stretching technique.
- Use a home massage device.
- Start an exercise program and get your muscles moving every day.
- See a mental health professional and reduce your stress level.
- Use an ice pack immediately after any muscle injury.
- Use moist heat to treat muscle inflammation
- Take a hot bath
Medications to Speak with Your Doctor About:
- nonsteroidal anti-inflammatory drugs (NSAIDs): Over-the-counter drugs like acetaminophen (Tylenol) and ibuprofen (Advil) can relieve pain and swelling.
- analgesics: Pain relievers such as lidocaine or diclofenac patch, tramadol, COX-2 inhibitors may be considered.
- muscle relaxants: Benzodiazepines and tizanidine (Zanaflex) can reduce muscle spasms.
- anticonvulsants: Gabapentin (Neurontin) and pregabalin (Lyrica) may relieve pain and reduce muscle spasms.
- tricyclic antidepressants: These are indicated to treat chronic pain, fibromyalgia, and nerve pain, which are conditions that resemble MPS.
- Botox injections: Botulinum type A is a potent neurotoxin that prevents muscle contractions and may have pain-relieving effects.
