Tendinopathy TOP TEN By Jill Cook PhD
Tendon pain and dysfunction are the presenting clinical features of tendinopathy. Research has investigated many treatment options, but consistent, positive, clinical outcomes remain elusive. We know that treatment should be active (eg, exercise-based), and that a consistent and ongoing investment in rehabilitation is required. It is important to maximise this investment by understanding (and conveying to patients) treatments that do not help. The following 10 points high- light treatment approaches to avoid as they do not improve lower limb tendinopathy.
1. Don’t rest completely.
Rest decreases the load tolerance of tendon, and complete rest decreases tendon stiffness within 2 weeks.1 It also decreases strength and power in the muscle attached to the tendon and the function of the kinetic chain,2 and likely changes the motor cortex, leaving the person less able to tolerate load at multiple levels. Treatment should initially reduce painful, high tendon load (point 2) and intro- duce beneficial loads (eg, isometrics3). Once pain is low and stable (consistent on a loading test each day), load can be increased slowly to improve the capacity of the tendon.4
2. Don’t prescribe incorrect exercise.
Understanding load is essential for correct exercise prescription. High tendon load occurs when it is used like a spring, such as in jumping, changing direction and sprinting.5 Tendon springs must be loaded quickly to be effective, so slow exercises even with weights are not high tendon load and can be used early in rehabilitation. However, exercising at a longer muscle tendon length can compress the tendon at its insertion.6 This adds substantial load and should be avoided, even slowly, early in rehabilitation.
3. Don’t rely on passive treatments.
Passive treatments are not helpful in the long term as they promote the patient as a passive recipient of care and do not increase the load tolerance of tendon.Treatments like electrotherapy and ice temporarily ameliorate pain only for it to return when the tendon is loaded.7
4. Avoid injection therapies.
Injections of substances into a tendon have been shown to be no more effective than placebo in good clinical trials.8 Clinicians who support injection therapies incorrectly suggest they will return a pathological tendon to normal. There is little need to intervene in the pathology as
there is evidence that the tendonadapts to the pathology and has plenty of tendon tissue capable of tolerating high load.9 Injections may change pain in the short term as they may affect the nerves, but should only be considered if the tendon has not responded to a good exercise-based programme.
5. Don’t ignore tendon pain. Pain usually increases 24 hours afterexcess tendon load. An increase in pain of 2 or more (out of 10) on a daily loading test should initiate a reduction in the aspects of training that are overloading the tendon (point 2). The overload is likely to be due to excessive spring-like movements such as jumping, running and changing direction.
6. Don’t stretch the tendon.
Aside from the load on a tendon in sport, there are compressive loads on the bone-tendon junction when it is at its longest length. Stretching only serves to add compressive loads that are detrimental to the tendon.10
7. Don’t use friction massage.
A painful tendon is overloaded and irritated (reactive tendon pathology). Massaging or frictioning the tendon can increase pain and will not help pathology.7 An effect on local nerves may reduce pain in the short term only for it to return with high tendon loads.
8. Don’t use tendon images for diagnosis, prognosis or as an outcome measure.
Abnormal tendon images (ultrasound and MRI) in isolation do not support a diagnosis of tendon pain as asymptom- atic pathology is prevalent. There are also no aspects of imaging, such as vascu- larity and ‘tears’, that allow a clinician to determine outcome.11 Pathology on imaging is usually very stable and does not change with treatment and reductionin pain, so images are not a good outcome measure.12
9. Don’t be worried about rupture.
Pain is protective as it causes unloading of a tendon. In fact most people who rupture a tendon have never had pain and do not present clinically, despite the tendon having substantial pathology.13
10. Don’t rush rehabilitation.
Tendon needs time to build its strength and capacity. So does the muscle, the kinetic chain and the brain. Although this can be a substantial time (3 months or more), the long-term outcomes are good if the correct rehabilitation is completed.14
The above 10 treatment approaches take valuable resources and focus away from the best treatment for tendon pain—exer- cise-based rehabilitation. A progressive programme that starts with a muscle strength programme and then progresses through to more spring-like exercises and including endurance aspects will load the tendon correctly and give the best long- term results.
Plantar fasciitis is inflammation of the plantar fascia and is the most common cause of heel pain. The plantar fascia is the thick band of connective tissue under the foot that runs from the heel bone at the back of your foot to the toes at the front. It essentially acts like a sling to support the arch of your foot.
What causes Plantar Fasciitis?
There are a number of causes including:
Age as it is more common in middle-aged people due to ‘sagging’ of the arch of the foot, but can occur in younger people who put a lot of load through their feet.Weaknesses can occur in the muscles that support the arch of the foot, which causes the plantar fascia to take an increased load which can irritate
Poor bio-mechanics can contribute to plantar fasciitis i.e. having flat feet or high archesWeight gain or excess weight can put extra load on the plantar fascia, irritating .
the tissues; this can also occur from the weight gain during pregnancy
Repetitive loading i.e. high level sports or working on your feet
Poor support from footwear i.e. worn or ill-fitting shoes
Arthritic foot joints can irritate the plantar fascia
Diabetic people have an increased chance of suffering from plantar fasciitis
Signs and Symptoms of Plantar Fasciitis
Pain at the base of the foot near the heel with weight-bearing
More pain after getting out of bed, or after prolonged sitting
Heel pain will be worse with the first few steps and will gradually improve as you move more
Generally your physiotherapist will be able to diagnose plantar fasciitis from your history, symptoms and a clinical examination.
Calf stretches often give relief to sufferers – it is important to stretch both calf muscles, so stretch with a straight leg and also a bent leg. Hold each stretch for 30 secs and repeat twice. Try to do this at least morning and night every day.
Freeze some water in an old water bottle and roll the bottom of your foot up and down on this.
Taping can offer you some relief while you are doing your exercises to off-load the plantar fascia.
Strengthening is an important component of treatment for plantar fasciitis as it improves the ability of the foot and ankle muscles to support the arch of your foot hence off-loading the plantar fascia.

Foot Pain OUCH!
You leap out of bed in the morning and you get stabbing pains in your heels or the arches of your feet. You hobble a few steps, and then hobble a few more until the pain reduces. Most of the day your feet feel OK …except when you tackle stairs or when you have been sitting for a while when the pain makes a reappearance.
Pain in your heel or the bottom of your foot is most commonly caused by Plantar Fasciitis. Your Plantar Fascia is the ligament that goes from the underneath of your heel to your toes. If you strain it, micro tears can form, which leads to swelling and sharp pain.
While most people experience the pain in their heel, some also get pain through to the arch of their foot. In about 70% of cases, the pain is in both feet, making walking a very painful experience.
You most commonly notice the pain first thing in the morning when you get out of bed and it reduces as your feet warm up with movement. It can reappear during the day after periods of rest or sitting, if you have been standing for a while, or when climbing stairs or ladders.
Plantar Fasciitis is more common in middle-aged people, although it can also affect younger people who use their feet a lot like joggers, dancers, or soldiers. That’s why it is also often called Joggers Heel.
Causes of Plantar Fasciitis
While the actual causes of plantar fasciitis are not known, there are risk factors that will increase the likelihood of you getting plantar fasciitis.
Overuse – excessive running, walking or dancing, or changing your training pattern so you dramatically increase hill running (for example).
Standing on hard surfaces
Flat feet or high foot arches (this is one time when average is better!)
Tight Achilles tendons or calf muscles
Your feet roll in when you walk or run
Ill-fitting shoes, worn out or unsupportive footwear such as thongs/slides
Walking barefoot on hard surfaces
First aid for Plantar Fasciitis
Generally, plantar fasciitis is gradual onset, which means it gradually increases in severity over time. If you ignore it and try to run through the pain, then the symptoms can get worse, ultimately leading to you changing your gait, limiting your activity or triggering the growth of heel spurs.
For initial symptoms, you need to rest, apply ice packs (15 minutes at a time every 2-3 hours), and take anti-inflammatory painkillers such as ibuprofen.
You don’t need a referral from a doctor to see a physiotherapist. If the pain is moderate then you can seek treatment with your Physiotherapist immediately as the sooner you begin treatment, the sooner you will experience relief.
Occasionally your plantar fascia can snap and you could hear a clicking or snapping sound, accompanied by swelling, intense pain and significant swelling. You need to see a doctor urgently if this occurs.
Physiotherapy & Treatment Options
Your physiotherapist will assess the extent of your injury, and will explore the causes of your injury.
Depending on your symptoms, you may have the soles of your feet taped or strapped to support your feet and reduce pain. You may also need to wear a plantar fasciitis brace or heel cups in the initial stages of healing.
Your physiotherapist will take you through a number of gentle stretching exercises for your feet, as well as exercises to address any tight Achilles tendons or calf muscles.
We will combine these with pain reduction techniques that you can do at home such as rolling your foot on a frozen water bottle or frozen golf ball to help ice your injury site.
Massage, joint mobilisation techniques, dry needling and ultrasound therapy will also be used to reduce swelling and restore movement.
For your footwear, we recommend you replace your joggers every 650km of use, and only wear shoes that support your feet while healing. Definitely no thongs or slides!
It also helps to put your shoes on first thing in the morning, before you take your first steps. Avoid barefoot walking on tiles or hard surfaces while you heal.
If the cause of your injury is your feet shape or foot pronation, you may need special orthotics. If this is indicated, we would conduct a walk/run assessment on you and have your technique analysed.
To maintain your fitness during your treatment, we recommend swimming and cycling. Don’t return to running until you have been pain free for at least one week, and then only run on soft surfaces until you rebuild your strength and stamina. If pain is felt at any time, then go back to swimming and cycling rather than running.
Unfortunately, Plantar Fasciitis is a long-term injury, and may take a number of months to fully heal even with the most aggressive treatments.
Things to Remember
Plantar Fasciitis is the most common cause of heel and arch pain, and is caused by micro tears to the plantar fascia.
It is a gradual onset injury and causes sharp pain when taking the first few steps in the morning or after rest.
Physiotherapy can treat plantar fasciitis, while reducing pain and increasing movement during healing.
Your physiotherapist may advise you of techniques for the improvement of your walk/running style, or provide you with solutions for arch support, to help prevent further reoccurrence.
Healing may take many months for full recovery.
As your cold-weather footwear makes the seasonal migration from the back of your closet to replace summer’s flip flops and bare feet, don’t underestimate the benefits of padding around naked from the ankles down.
Barefoot activities can greatly improve balance and posture and prevent common injuries like shin splints, plantar fasciitis, stress fractures, bursitis, and tendonitis in the Achilles tendon, according to Patrick McKeon, a professor in Ithaca College’s School of Health Sciences and Human Performance.
The small, often overlooked muscles in the feet that play a vital but underappreciated role in movement and stability. Their role is similar to that of the core muscles in the abdomen.
“If you say ‘core stability,’ everyone sucks in their bellybutton,” he said. Part of the reason why is about appearance, but it’s also because a strong core is associated with good fitness. The comparison between feet and abs is intentional on McKeon’s part; he wants people to take the health of their “foot core” just as seriously.
The foot core feedback loop
McKeon describes a feedback cycle between the larger “extrinsic” muscles of the foot and leg, the smaller “intrinsic” muscles of the foot, and the neural connections that send information from those muscle sets to the brain.
“Those interactions become a very powerful tool for us,” he said. When that feedback loop is broken, though, it can lead to the overuse injuries that plague many an athlete and weekend warrior alike.
Shoes are the chief culprit of that breakdown, according to McKeon. “When you put a big sole underneath, you put a big dampening effect on that information. There’s a missing link that connects the body with the environment,” he said.
Muscles serve as the primary absorbers of force for the body. Without the nuanced information provided by the small muscles of the foot, the larger muscles over-compensate and over-exert past the point of exhaustion and the natural ability to repair. When the extrinsic muscles are no longer able to absorb the forces of activity, those forces are instead transferred to the bones, tendons, and ligaments, which leads to overuse injuries.
It’s not that McKeon is opposed to footwear. “Some shoes are very good, from the standpoint of providing support. But the consequence of that support, about losing information from the foot, is what we see the effects of [in overuse injuries].”
Strengthening the foot core
The simplest way to reintroduce the feedback provided by the small muscles of the foot is to shed footwear when possible. McKeon says activities like Pilates, yoga, martial arts, some types of dance, etc. are especially beneficial.
“Anything that has to deal with changing postures and using the forces that derive from the interaction with the body and the ground [is great for developing foot core strength],” he said.
McKeon also described the short-foot exercise, which targets the small muscles by squeezing the ball of the foot back toward the heel. It’s a subtle motion, and the toes shouldn’t curl when performing it. The exercise can be done anywhere while seated or standing, though he recommends first working with an athletic trainer or physical therapist to get familiar with the movement.
He notes the exercise seems to have especially positive results for patients suffering from ankle sprain, shin splints, and plantar fasciitis. It’s even been shown to improve the strain suffered by individuals with flat feet.
The payoff could be more than just physical, as there could be financial savings. With strong feet, McKeon suggests that — depending on the activity — consumers may not need to invest hundreds of dollars in slick, well-marketed athletic sneakers (though he doesn’t recommend going for the cheapest of cheap sneakers, either). People with a strong foot core can actively rely on the foot to provide proper support, rather than passively relying on the shoes alone.
“You might be able to get a $50 pair of basketball shoes that don’t have the typical support that you’d expect. Because you have strong feet, you’re just using the shoes to protect the feet and grip the ground,” he said.
The easiest way to get started on strengthening the small muscles of the foot, though, is to kick off your shoes in indoor environments.
“The more people can go barefoot, such as at home or the office, is a really good thing,” McKeon said.
