What is your Rotator Cuff and What does it do?

 

You may have seen videos or posts online about people talking about a specific area of your shoulder known commonly as the “Rotator Cuff” and wondered what they were on about. Your shoulders do a lot of important things you might take for granted! They help you get something off a high shelf, comb your hair, or play a game of cricket.

It’s a complicated process that your body makes look easy. And your rotator cuff is a big part of that. It protects and stabilizes your shoulder joint and lets you move your arms over your head. It’s importance is widely used in sports like swimming, tennis and netball.

In New Zealand healthcare, shoulder injuries have one of the highest prevalence when it comes to ACC claims and overall cost. Within this, rotator cuff injuries are among the most common pathologies affecting New Zealanders. Other pathologies include acromioclavicular injuries, dislocations, osteoarthritis and frozen shoulder.

 

So, what exactly is the cuff and how does it influence the shoulder?

  • The rotator cuff (RC) is a combination of four muscles that run through and attach onto specific areas of the humeral head (top of the arm bone).

  • Supraspinatus, Infraspinatus, Teres minor and Subscapularis are the four muscles comprising the RC and each one plays an important role however they all contribute to shoulder stability:

Supraspinatus

Infraspinatus

Teres Minor

Subscapularis

A thin triangular muscle that helps perform abduction

A thicker, triangular muscle that performs external rotation.

The smallest muscle of the cuff, helps with rotation as well

The largest muscle of the cuff performs internal rotation (arm behind your back!)

 

 

Many people suffer from shoulder pain, so here are the most common injuries that can happen at the rotator cuff:

Rotator Cuff Tear:

A rotator cuff tear is often the result of high levels of load over a short amount of time or a high impact force stressing one or more of the tendons/muscles. Fortunately, majority of tears are partial. Tears are more common in people with jobs that involve heavy loading or lifting or in high impact sports like rugby. It also can happen suddenly if you fall on your arm or try to lift something heavy. Common and easily treatable with conservative management by a physiotherapist, a rotator cuff tear can come right.

Rotator Cuff Tendinopathy:

A rotator cuff tendinopathy is the most common shoulder pain complaint/injury resulting in inflammation and irritation of one or more of the cuff tendons. This pathology is more common in individuals who have an occupation where repetitive use of the shoulder, particularly in an overhead position such as carpenters or painters, or individuals that play highly repetitive, throwing sports like tennis, baseball or volleyball. Once again, this injury is treatable by a physiotherapist, conservative management can be very effective in treating these injuries with a thorough, well planned exercise program to help get patients back to doing what they love.

Majority of people experience pain around the shoulder joint, with some movements being highly provocative. Tenderness on touch at the affected site is also common – this helps your physiotherapist hone in on potentially which tendon is causing those problems!

 

Medical management vs Physio management

 

Medical management will be advised by your local GP if you decide to see them first. They might prescribe NSAIDs (anti-inflammatory medications such as ibuprofen) to help with the pain you’re experiencing and recommend you see a physiotherapist. Depending on your injury as well as your ability to function, surgery may be an option if conservative medical and physio treatments don’t help. Most people get by without the need of surgery but some tears can be too large to heal without the use of surgical intervention.

Physiotherapy management is designed around reducing pain and disability, restoring range of motion and helping people return to work or sports to perform how they were prior to the injury. In the early stages of these injuries, rest and ice and/or heat are recommended to allow the inflammation to settle – then your physiotherapist will begin to introduce a detailed exercise program, this may include:

  • Isometric (static hold) exercises
  • Resisted movements using bands
  • Range of motion exercises to restore lost movement
  • Functional loading – task specific or sport specific

If this is successful, the last step is to build back up the strength that was lost over time – this is done by concentrically (against gravity) loading the affected tendons/muscles in a way that they adapt and lay down more tissue, grow and becoming stronger in hopes that you get to return to what you enjoy!

 

 

Lifting Mechanics

IS IT DANGEROUS TO LIFT WITH A BENT BACK?

One common belief about lifting is that rounding your back when lifting an object is considered dangerous while lifting with a straight back is considered safe…

 

 

However, there is a lot of misinformation circulating around lifting mechanics and what is deemed “good technique” versus “bad technique.”

Here are some key myths and misinformation that you may have heard:

 

A ROUNDED BACK WHILE LIFTING OVER STRESSES THE BACK MUSCLES AND LIGAMENTS

  • Research has shown that regardless of lifting position, whether you’re stooped, squatting or weightlifting, your back has to produce the same amount of force. Statistically speaking, it’s not significantly different.

 

 

FLEXING THE SPINE WHILE LIFTING INCREASES THE LOAD ON THE LUMBAR DISCS

  • Under heavy loads, discs are unlikely to fail unless >95% flexion is achieved (which is near impossible)

  • With low loads, the disc is unlikely to fail unless you do thousands of repetitions continuously

  • Your body is an amazing adapter, this includes discs! Your discs can adapt and become more and more able to handle loads when stressed appropriately

 

THESE COMPOUND TO CAUSE INJURIES AND PAIN TO THE BACK MUSCLES AND DISCS

  • Resistance training has demonstrated through countless studies the ability to increase bone mineral density (BMD) of the lumbar spine. BMD is actually positively associated with the strength of the spinal discs and ligaments at that level. With appropriate loading and training, disc, ligament, bone and muscles are going to adapt favourably

 

A NEUTRAL SPINE IS SAFER, STRONGER, MORE EFFICIENT AND BETTER TO LIFT WITH

  • There is no significant difference between activities that encourage more spinal flexion and one’s that do not in the long term

  • Lifting with lumbar flexion is not a risk factor for low back pain

  • Research has shown lifting with a bent back is more metabolically and neuromuscularly efficient

  • When the spine is in extension during bent over activities, the hip is actually flexed to a greater degree – decreasing the ability for the glutes and hamstrings to create as much internal torque. Flexing the spine reduces this effect and reduces the moment arm for the hip extensors

 

STOP BACK PAIN & INJURIES BY LIFTING WITH A NEUTRAL SPINE

  • Your lumbar spine flexes every time your hip flexes! It is impossible to isolate one versus the other. It is also impossible to not flex while doing common movements

  • Extreme flexion however (>/=100%), may pose an increased risk under heavy loads, but not at light loads

 

You may still be wondering why you have back pain (stay tuned for our next blog!). Your pain may not be directly related to your lifting strategy.

 

 

Could you have pain with forward bending? Absolutely.

Is bending at the lumbar spine an increased risk for pain or injury? In the vast majority of situations, no.

If I have pain with forward bending, is it bad to temporarily limit doing so? Not at all.

Should I fear bending at the spine with or without pain or injury? No. Being fearful of flexing/moving your spine is actually a stronger predictor of disability and back pain.

 

Work on moving through your spine, after all it’s what it is designed to do! Choose comfortable movements and gain confidence over time, then build up your strength gradually with resistance training – try and not to push too fast, we want nice, healthy adaptation! Give your body time to adapt, back pain is not quick fix sometimes but you are resilient and with healthy, normal movements and some patience, you will be okay.

Disorders of the Achilles Tendon

Basic Anatomy

The Achilles tendon is the largest tendon in the human-body. It is a band of tissue that connects your calf muscles to your heel bone (calcaneus). This tendon primarily facilitates general mobility such as walking, running, climbing stairs, jumping, and standing on your tip toes, by helping to raise the heel off the ground.

 

 

Common Achilles Pathology

Achilles tendinitis and tendinosis are two common disorders and are typically classified as overuse injuries.

Achilles tendonitis involves inflammation of the Achilles tendon. Inflammation is the body’s natural response to injury or disease, and often causes swelling, pain, or irritation. This inflammation is typically short-lived. Over time, if this is left resolved, the condition may progress to degeneration of the tendon- Achilles tendinosis, in which case, the tendon loses its organized structure and is likely to develop microscopic tears.

There are two types of Achilles tendonitis and it is based on which part of the tendon is inflamed:

  • Insertional Achilles tendonitis affects the lower portion of your tendon where it attaches to your heel bone.
  • Non-insertional Achilles tendonitis involves fibres in the middle portion of the tendon and tends to affect younger people who are active.

In both non-insertional and insertional Achilles tendinitis, damaged tendon fibres may also calcify (harden) and often bone spurs (extra bone growth) develop with insertional Achilles tendinitis. Achilles tendonitis may also increase your risk of sustaining an Achilles tendon rupture (tear).

Causes

Typically referred to as “overuse” conditions, Achilles tendonitis and tendinosis are often caused by the sudden increase in repetitive activity involving the Achilles tendon. This can put too much stress on the tendon too quickly, that can then lead to micro-injury of the tendon fibres. Because of this ongoing stress on the Achilles, the body is not able to repair the injured tissue. The structure of this tendon is then modified, resulting in continued pain and other symptoms. The Achilles tendon also has poor blood supply that makes it more susceptible to injury and may make recovery from injury slow.

Common factors that may lead to the development of disorders of the Achilles tendon include:

  • Weak and/or tight calf muscles
  • Rapidly increasing the amount or intensity of exercise within a short span of time
  • Hill climbing or stair climbing exercises
  • Presence of bony spurs in the back of your heel
  • Changes in footwear – especially changing from wearing high-heeled shoes to flat shoes
  • Wearing poor fitting, inappropriate, or worn out shoes during sporting activities
  • Exercising without adequate warm-ups and stretching
  • A sudden sharp movement which causes the calf muscles to contract and the stress on the Achilles tendon to be increased. This can cause the tendon fibres to tear.
  • Excessive mobility
  • Poor feet positioning and biomechanics (excessive pronation and flattening of the arches of the foot)

 

Symptoms

Achilles tendon pain: Causes. when to see a doctor, and treatment

 

Common symptoms include:

  • Pain and stiffness along the Achilles tendon especially first thing in the morning
  • Pain along the tendon or back of the heel that worsens with activity
  • Severe pain the day after exercising
  • Visible thickening of the tendon
  • Tenderness to touch
  • Bone spur
  • Swelling that is present all the time and gets worse throughout the day with activity

If you have experienced a sudden “pop” in the back of your calf or heel, you may have torn your Achilles tendon. Please seek urgent medical attention if you think you may have torn your tendon.

Diagnosis

If Achilles tendonitis or tendinosis is suspected, please deter from any activity or exercise which causes the pain. It is advisable to see your doctor or physiotherapist as soon as possible so that an accurate diagnosis may be made and appropriate treatment recommended.

You will be asked about the nature and duration of your symptoms and the medical professional assessing you will have a look at your foot and ankle. Ultrasound scanning may be used to evaluate the damage to the tendon and/or surrounding structures.

An MRI may be recommended if symptoms persist. X-rays may also be taken to rule out other disorders which may cause symptoms like Achilles tendonitis and tendinosis.

Treatment

Treatment will depend on the nature, severity, and length of the injury. Generally speaking, the longer the symptoms are present before treatment commences, the longer the timeframe until full recovery is attained.  Full recovery may take between three and nine months.

Initial treatment options in the early stages may include:

  • Rest – to avoid further injury to the area
  • Ice – to reduce inflammation
  • Elevation – to reduce swelling
  • Non-steroidal anti-inflammatory drugs to reduce pain and inflammation.

 How physiotherapy can help:

Physiotherapy typically focuses on two main areas: treatment and rehabilitation. Treatment may entail massage, shockwave therapy, acupuncture, gait re-education, and gentle stretching, whereas, rehabilitation predominantly entails strengthening of the Achilles and surrounding musculature.

Strengthening of the muscles surrounding the Achilles tendon facilitates healing in the tendon itself. Strengthening is attained through the utilization of specific exercises, that will be taught by your physiotherapist. It is common for the rehabilitation programme to take up to three months.

5 COMMON MISCONCEPTIONS ABOUT PHYSIOTHERAPISTS – PART 2

Myth 1: When you see a physiotherapist you just lie on the bed and get given an ice or heat pack.

At Physio Fusion we use an active approach to treatments. Physiotherapy will include manual hands-on therapy to facilitate tissue healing and tissue load tolerance alongside an exercise program individualized to your needs.

Myth 2: If I have elbow pain then the injury must be in my elbow.

The area of pain is not always the area that is the issue! It may be a result of a previous injury that was never fully rehabilitated. This is where we can help you out. Our assessment will consist of gathering information on your presenting complaint, any previous injuries or traumas (physical and emotional) and a medical history followed by an objective evaluation of your body. This allows us to get to the root cause of the pain and manage your symptoms most effectively.

Myth 3: I can’t do any of my normal activities while I attend physiotherapy.

Not true! Our Physiotherapists want to keep you as functional as possible whilst allowing your injury to heal. During the initial assessment your physiotherapist will determine what activities you can do and advise you on those that must be avoided. You will then be given clear and timely objectives to ensure you reach your goals to get you back doing what you love!

Myth 4: A scan will show me exactly what is wrong.

Sometimes it will, but sometimes it won’t. It’s no secret that our bodies change as we age, so even people without pain are likely to have an imperfect scan. Medical imaging can sometimes play an important role in the assessment and management of your musculoskeletal issue. When necessary, your physiotherapist will know what type of imaging to refer you for.

Myth 5: Is cracking my back/neck/knuckles bad for me?

There is no strong evidence to suggest that ‘cracking’ your joints causes degeneration, laxity or instability. The ‘cracking’ occurs when we move a joint to its end range. The audible sound happens because of ‘cavitation’ in the joint; this involves gas bubbles popping within the fluid surrounding the joint as pressures change.

But is it good to crack?

Self manipulation can be a helpful way to reduce the feeling of stiffness or tightness. If you are finding that you need to ‘crack your joints’ often it is good to know that there are many other more beneficial ways to provide greater long term relief.

Top tips:

  1. Ask your physiotherapist to provide you with some specific exercises to help you overcome the feeling of stiffness or tightness.
  2. Move regularly and avoid movements or positions that exacerbate your symptoms until you have been seen by your physiotherapist.
