If you have sustained an ACL ( Anterior Cruciate Ligament of  the knee) tear and is considering an ACL surgery, you would find it useful to know more about the latest research discussion on ACL surgery versus Physical therapy management.

Knock Knees – Can I reverse it? (Part 2)

August 19, 2010

In the previous entry for Knock Knees, we discuss about the different types of knock knees and the contributing factors of it. Now, we will talk about the problems of this condition and ways we could get rid of it.

The Problems of this condition

The alignment of the knee joint in someone with knock knees is such that there is an increased force on the medial (inner) part of the knee joint. This can predispose the knee joint to osteoarthritis because of the increased loading on the medial compartment.
Symptoms from this may not even present within the knee joint, you may have ankle problems or hip problems as a result of having knock knees.

How do I get rid of it?

External aids:

1. Orthotics

The knee joint may appear to be misaligned if the foot is not biomechanically sound. This means that someone with a very pronated/inverted/flat feet may be at risk of developing a symptoms similar to someone with knock knees. Placing an insole or orthotics device may help correct the foot position, and indirectly the alignment of the knee joint.

2. Knee braces

These can help prompt correct alignment of the knee joint, but may create a degree of dependency.

3. Strengthening

A physiotherapist can design an exercise program to help strengthen weak muscles. By focussing on the specific muscles that require strengthening, you will put your body is a safe healthy direction, and will be able to train for all types of sporting challenges and limit your risk of injury.

4. Stretching

Stretching is an important component of knock knee reversal. When a joint has spent all it’s time in a misaligned position, certain structures will shorten and become stiff. Stiffness in the joints and muscles will make it very difficult to train and strengthen the area. A physiotherapist can assess the position of your knee, ascertain which structures are tight, and give you an appropriate stretching program.

 

I have corkie (bruise)? What should I do?

August 12, 2010

Almost everybody experiences corkies or bruises during his lifetime. Some people are more prone to develop corkies than others. In many cases you don't have to worry about a corkie but it is important to know at which stage you should see a doctor.

What are Corkies?

Corkies are also known as bruise or contusion. They are a type of a relatively minor bleeding (hematoma) of your tissues in which small blood vessels are damaged after a trauma. Bruises can occur at different layers of the body and include skin, deeper tissue, muscles and bones. Most bruises happen after a fall, hitting an object or getting a hit during sports. In many cases it takes a while till you notice a corkie and you will not immediately feel the symptoms right after an incident. Typical areas for corkies are at the front of the thigh, shin, at the frontal pelvic bone (hip pointer or iliac crest) and on your forearms.

How do I know I have a corkie/bruise and what are the symptoms?

A corkie presents with the following symptoms:

  • initially short severe pain during trauma (hit, fall as mentioned above)
  • later the pain reduces and becomes more of a local tenderness
  • swelling (not always)
  • bleeding (hematoma- dark blue colored spot on the skin)
  • pain during action /use

What are the contributing factors?

The size and shape of a bruise is influenced by several factors such as age, condition- color and type of tissue. Furthermore the location, striking force of a hit or blood disorders (coagulation problems) have an impact on the size and shape of a corkie.

What should I do when I have a corkie?

The treatment of light corkies includes:

  • RICE (Rest, Ice, Compression, Elevation) to reduce pain and swelling
  • painkillers
  • soft stretching after a few days when the pain settled down
  • after the inflammatory phase (3-5days) heat to loosen up tight muscles

When should I see a doctor?

You should see a doctor if you have a moderate-severe corkie/bruising. This is indicated if:

  • you have severe pain and tenderness
  • you develop a massive swelling
  • movements of the affected area are very painful
  • you have a big corkie without any explanation/reason

Note: If you have unexplained bruises which occur very frequently over a long period of time it is advisable to see a doctor to rule out skin or blood disorders (platelet or coagulation disorder). Furthermore unexplained bruising may also be a warning sign of child abuse, internal bleeding or other serious health problems. The usage of several drugs (e.g. steroids, blood thinners) can cause easier bruising.

How long does it take for the corkie to disappear?

Normally light bruises heal within 2-3 weeks. Depending on the severity and the individual healing process it can take longer. Deeper bruises take more time to heal.

Maybe it’s not Plantarfasciitis but Heel Fat Pad Syndrome

July 29, 2010

Do you have heel pain? And think it is Plantar Fasciitis?

Maybe not, it might be another type of heel pain called the Heel Fat Pad Syndrome.

What´s the difference between the Plantar Fasciitis and Heel Fat Pad Syndrome?

As shown in the illustration, both structures are in the same area of the heel whereas the plantar fascia (illustrated as plantar apponeurosis) is covered by the fat pad. The plantar fascia attaches at the toes and forms the medial (longitudinal) arch of the foot. It provides static support of the medial arch and dynamic shock absorption. The main functions of the fad pad is shock absorption of stress during heel strike (heel contact during walking).

While both the heel fat pad and plantar fascia can be a source for heel pain, the contributing factors, clinical signs and symptoms and management for them differ.

Plantar Fasciitis

Plantar fasciitis is an overuse condition of the plantar fascia.

Contributing factors: It is often seen in people with foot deformities e.g. flat feet (low arches) or pes cavus (high arches). This deformities can lead to an excessive strain at the fascia during walking and hence cause pain. Other risk factors which can lead to increased stress in the fascia are inappropriate or non-supportive footwear, reduced ankle mobility, obesity and work related weight bearing.

Clinical signs and symptoms: A typical clinical sign is swelling of the plantar fascia and can be confirmed by ultrasound investigations. People with plantar fasciitis classically have a gradual onset of symptoms and feel their pain more on the inner side of the heel. Further symptoms are acute tenderness of the inner side of the heel, a tight plantar fascia and pain during stretching of the fascia. Especially the first steps in the morning or after rest are painful. The pain seems to decrease after a few minutes, and returns as the day proceeds and time on the feet increases.

Management: Due to the tightness of the plantar fascia that leads to pain, treatments involve stretching and massaging to release the tight fascia and calf muscles. Other management include avoiding aggravating activities (e.g. wearing heels), cold therapy (R.I.C.E), anti-inflammatory drugs, taping to to relief pain and lastly it is crucial to strengthen calf muscles that have weakened during the pain process. Some patients who are still symptomatic after conservative treatment might need surgery.

Heel Fat Pad Syndrome

Heel fat pad syndrome is often caused by a decreased elasticity of the fat pad. A fall onto the heel from a height or chronically excessive heel strike with poor footwear can also lead to heel pain.

Contributing factors: Increased age and weight decreases the elasticity of the fat pad.

Clinical signs and symptoms: Compared to plantar fascitis, fat pad related heel pain is felt more at the outer side of the heel especially when the heel gets loaded (heel strike). MRI investigations will reveal changes in the fat pad showing signs of swelling.

Management: Treatments aimed at unloading the heel by avoiding aggravating activities. In an acute situation the R.I.C.E. rule (Rest Ice Compression Elevation) should be applied and anti inflammatory drugs are given. Further treatment includes taping, the use of a silicone gel heel pad and use of appropriate footwear.

For Swimmers : Common Injuries, Treatment and Prevention tips

July 7, 2010

Do you swim leisurely or competitively? If yes, continue to read on.

Recently, one of our physiotherapists, Chng Chye Tuan was interviewed by Style:Men on the common musculoskeletal injuries face by swimmers in the July's issue. Do read on to find out what he has to share.

What are the common problems competitive/regular swimmers face?

The most common swimming injury is the rotator cuff impingement / tendonitis.

  • Ball joint of the shoulder compress the tendon against the roof of the socket (acromion) in 2 phases of freestyle – the pullthrough and recovery phase.
  • Pull-through phase in the freestyle stroke involves the arm pulling against the resistance of the water. The outstretched arm with internal rotation of the shoulder stresses the tendon and pinched it against the acromion. The pinching can irritate the tendons and give a sudden catching kind of pain.
  • The recovery phase involves a body roll and raising the elbow up and out to allow the upper limb to recover out of water efficiently otherwise the shoulder will be working harder at an awkward position to pull the hand out of water.
  • Repeated pinching will give rise to inflammation and fraying of the soft tissues.

What are the usual causes?

The usual contributing factors are mainly due to over training, poor technique, poor core muscles and unilateral breathing.

  • Over training – when muscles are fatigued, the stabilising component from the rotator cuff muscles becomes compromised thus increasing the chances of the humeral head translating upwards and impinging the rotator cuff tendons. The ball component has to be centralised within the socket of the shoulder to optimise stability and muscle function.
  • Technique – the freestyle and backstroke requires the swimmer to roll their trunk such that the drag is minimise and the propulsion force can be maximised. Too much drag will increase the resistence, tiring out the shoulder muscles sooner.
  • Strong core muscles and truck control enable the swimmer to do a body roll along the longitudinal axis so that it is easier for the shoulder to pull the upper limb out of water.
  • Unilateral breathing can develop a muscle imbalance leading to improper muscle activation and overuse.

What kind of treatments do you recommend?

An assessment of the shoulder girdle, spine and core strength will be performed to be able to properly manage a swimmer’s shoulder.

A key treatment to approach the swimming shoulder is to rehabilitate the rotator cuff muscles to be able to centralise the humerus at different shoulder positions.

Exercises will be prescribed to specifically target these rotator cuff muscles, correcting any imbalances. These exercises include strengthening the weak muscles to improve dynamic support and also stretching exercises to the tight muscles pulling the joint out of position.

As most competitive swimmers will not be able to cease training completely, kinesiotaping complements the rehabilitation therapy by improving the rotator cuff’s ability to stabilise the shoulder joint via better joint awareness from the corrective

Are there preventive measures that swimmers can take to minimise such problems?

Regular stretching exercises, core stability training and work on the techniques. During the early stage of feeling the impingement (catching or pinching) pain, seek help from a sports physician or physiotherapist as soon as possible.

Management for ITB friction syndrome

June 16, 2010

Follow up to our last ITB article, we have identified three conditions that contributes to the tightening of the ITB. They are weak outer hip muscles, incorrect training methods and bio-mechanical gait issues. In this edition, we seek to address these three main problems, looking at strengthening those weak hip muscles, rectify those poor training methods and biomechanical issues, outlining the practical management of iliotibial band friction syndrome (ITBFS) associated with running athletes.
 
Weak outer hip muscles
 
Early stage of rehabilitation aims to redress muscle weakness in the hip which may be considered as a major factor in the development of this condition. Thus, strength and conditioning exercises should focus on the muscle called gluteus medius. The reason why we target the gluteus medius is because it functions as an important stabilizer to control and decelerate adduction of the thigh during running. Poor endurance and control of the gluteus medius leads to gait alteration and ultimately ITBFS. Furthermore, to decrease tension along the ITB, the use of a foam roll and performing isolated stretches for tight muscles can be particularly effective in releasing myofascial restrictions. Below are some recommended exercises.
 
ITB Proximal Stretch

  • To stretch the IT band of your left leg, stand with your left side facing the wall.
  • Cross your left leg behind your right, while using your left hand to help balance.
  • Put your weight on the right leg and lean against the wall by pushing your left hip towards the wall.
You should be able to feel the stretch in your left hip and down the IT band






ITB release with Foam Roller



      • Rest the side of the thigh on the foam roller, positioning the foam roller just above the knee.
      • Support yourself with your right arm and right foot to keep your  balance.
      • Roll yourself down the mat, rolling the foam roller from the knee up to the hip and then down to the knee.
      For a trigger point release, you can sustain pressure on the painful spot for 30 seconds.




      Clam shell in side lying 
       
      • Lie on left side to work on the right gluteus medius muscle.
      • Keep spine in neutral and not sagging down towards the mat
      • Keep the heels together and the knees at a right angle
      • Lift the right knee up without rotating the pelvis and back.
      You should feel it on the muscle behind the hip bone
                                                            




      Side planks

       
      • To work on your right, lie on your side with your right hand on the ground or use an exercise mat.
      • Lift your trunk and pelvis up to form a plank
      • Maintain a straight trunk and pelvis alignment
      • Hold for 30 secs

       

      Training methods

      Having re-established muscle balance around the hip, you should now be ready to take full bodyweight on the affected leg while maintaining optimal body alignment. To start getting back to running, we recommend running every other day for the first week, starting with easy sprints on level ground. It is important to note that studies have shown that ITBFS occurs mainly at, or at slightly less than, 30 degrees of knee flexion. Thus, it is necessary to avoid downhill running because the knee flexion angle at footstrike is reduced, causing strain on the ITB. Biomechanical studies have also shown that faster-paced running is less likely to aggravate ITBFS. This is because as the foot strikes the ground, the knee is flexed more than 30 degrees, avoiding the range where the strain occurs. Incorrect training practices can also contribute to the condition, such as starting a demanding routine of sport or exercise immediately following a return from injury, or otherwise expanding your training too rapidly.
       
      A gradual increase to your training mileage (e.g. 2-3km per week) cannot be over emphasized. Your body won't get used to running long distances, unless it has run those distances on a regular basis. As the body needs rest between those runs, thus it is recommended that there should be no more than two long runs per week and moderate distance on the other days. Long training runs should be conducted at an aerobic capacity where you can talk and run at the same time. After a run, stretch and then ice the outside of the knee for 5-10 minutes. Last but not least, always train at an appropriate intensity. Training at higher intensities (>80% of Max. Heart rate) will lead to lactic acid production, which will fatigue the muscles and increase the chance of injury. To monitor the level of training intensity, a heart rate monitor may be a useful device. 

      Biomechanical Gait issues

      Always wear appropriate shoes that give you proper support. A wet footprint test is a common method for determining your foot type. Get your feet wet and stand on a flat surface that will allow your footprint to be shown. Compare your footprint to the images below.
       
      X

      foot
       
      Now that you know your foot type, approach a knowledgeable salesperson at a running specialty store and they will be able to help you find the right shoes for you. A semi-rigid orthotic may also be useful for someone who have excessively flat feet or high arches, in bid to improve function by supporting the foot segments during gait. The orthotic is worn in the shoe and it helps by changing the position and time sequences talking place in the foot during running so that no one muscle or group of muscles have to work longer and harder than it should.

      Why Badminton Players Get Tennis Elbow?

      June 15, 2010

      What is Tennis Elbow?
       
      The term “Tennis Elbow” is commonly used to describe pain located at the lateral aspect of the elbow. It is usually caused by overuse of muscles at the elbow that produces wrist extension (namely the extensor carpi radialis brevis – the ECRB), which leads to small tears and scarring of the muscles.

      Signs and Symptoms
       
      Interestingly, many people suffer from Tennis Elbow don’t actually play tennis. It could happen to any individuals whose daily activities involve repetitive wrist extension or hand gripping, such as badminton or squash players, typists, or sewers.
       
      Symptoms of this condition may include:
      • Diffuse pain over lateral elbow just below the lateral epicondyle;
      • Reduced grip strength;
      • Reduced ability to lift a heavy object; or
      • In racquet game players, reduced ability to perform a backhand.
      • Some people with tennis elbow also experience tingling sensation or numbness spreading over the forearm and hand.
      What else may cause elbow pain?

      It is important the Tennis Elbow is diagnosed correctly for the proper treatment. Other causes of medial /lateral elbow pain may include nerve entrapment, ligament strain, radiohumeral joint synovitis, radiohumeral joint bursitis, or pain referred from neck. Your medical professional will be able to perform tests eliminate the other possible diagnosis.
       
      The other side of the coin
       
      Golfer’s Elbow, on the other hand, refers to pain on the inside of the elbow. The pathology and treatment of this condition are similar with Tennis Elbow except that the muscles involved now are located on the inside of the elbow.

      How it is treated
       
      Treatment of Tennis Elbow usually starts with control of the pain, such as:
      • Therapeutic ultrasound, heat-retaining braces;
      • Soft tissue therapies like deep tissue massage, trigger point treatment, myofacial release;
      • Stretching of the tight wrist muscles;
      • Specific mobilization techniques combined with gripping exercises;
      • Taping, corticosteroids injection, and acupuncture are sometimes helpful;
      • Neck and nerve mobilization can also be considered if necessary.
      Strengthening of the wrist muscles can be initiated soon after the pain is better controlled. Muscles that produce wrist extension or wrist flexion need to be both addressed.
      • Focus should be put to achieve good control of the wrist to prevent wrist from functioning at extreme ranges, either into extension or flexion;
      • Racquet technique needs to be carefully assessed to correct any technical faults, especially wrist arm control in back hand strokes;
      • Encouraging gripping that focuses on hand muscles (the Duck grip), rather than gripping that only focuses on forearms muscles (the Finger grip).

      Skier’s thumb? Gamekeeper’s thumb?

      June 11, 2010

      The ulnar collateral ligament is a strong, fibrous band that maintains stability on the inside border at the base of the thumb. The ligament prevents excessive thumb movement away from the hand.

      How is it Injured?
      Injuries usually occur as a result of a sporting mishap. It is commonly seen in skier’s, footballers and rugby players. The ligament may also be directly damaged as a direct result of a fall or other trauma.
      The ligament is typically damaged as the thumb is forced away from the hand stretching or rupturing the UCL.

      UCL injuries are commonly referred to as
      "Skier's thumb" AND "Gamekeeper's thumb"

      Skier's thumb refers to an acute injury to the ulnar collateral ligament. This involves a significant stress to the ligament which stretches the ligament beyond its normal limit. If the ulnar collateral ligament is stretched far enough it will rupture
      Gamekeeper's thumb refers to chronic injury causing a stretching of the ulnar collateral ligament over time. This is usually due to a lower grade repetitive trauma.

      Signs and Symptoms?
      • Pain and tenderness over the base of the thumb
      • Swelling and or bruising over base of the thumb
      • Pain with movement of the affected thumb and difficulty gripping objects
      • Instability or catching of the thumb on movement
      Treatment?
      Treatment is highly varied and dependent on a number of factors.
      • Severity/grade of the injury
      • How long ago injury occurred
      • Patient age
      • Physical demands of the patient
      • Likely adherence of patient to protocols

      If only a partial rupture has occurred patients are either placed in a mild cast or wrist splint (known as thumb spica) for 4 to 6 weeks.

      If a complete rupture has occurred or there is gross instability of the thumb surgical intervention is most likely. Surgery is most effective when executed within the first few weeks following injury.
       
      What is the recovery after ulnar collateral ligament repair?
      Following surgery, patients will be placed in a cast for four to six weeks to protect the repaired ligament. During this time gentle range of movement exercises will be commenced progressing to stretching and strengthening exercises. Return to sports and full activity usually occurs 3 to 4 months after surgery.

      Running, Not Doctors…

      June 9, 2010

      One great fear of runners is visiting a doctor for their injuries and being told to stop running. This news article in the New York Times (Sports Injuries: When to Tough It Out) covers some of the issues surrounding the question,  "should I or shouldn't I see a doctor for my pain?".

      But the article left a few gaps for those aches and pains that don't seem serious enough to warrant a visit to the doctors.

      Closing the Gap

      One of the first thing to do is to ease off and reduce your training intensity. You can ease off in one of these four areas

      1. Duration – shorter runs
      2. Speed – slower or constant
      3. Frequency – fewer sessions per week with more rest in between
      4. Terrain – less challenging terrain – flat ground rather than uphill

      Another thing is to stretch more regularly. If pain is new, do apply MICER. MICER is explained here in a post reply to a reader's question.

      When to see the doctor?

      Ease off your training intensity for a few weeks and monitor closely. If the pain persist, you may have to see a doctor or therapist to determine the underlying problem. Assuming that is not something serious like a torn ligament, there may a underlying bio-mechanical fault that needs to be identified and corrected.

      Eccentric ankle evertor muscle strengthening is better than concentric strengthening after a lateral ankle sprain

      May 29, 2010

      Recently, we have an article published on how to manage recurrent ankle sprain. Now let us look at how to further reduce the incidence of your next sprain.
       
      Herve Collado and fellow researchers from France found that rehabilitation focusing at eccentric strengthening of ankle evertor muscles has shown to restore strength of first time lateral ankle sprain is better than concentric rehabilitation in lateral ankle sprain.
       
      In the study, 18 subjects, aged 23-25 years who have type I and II lesion of the first time lateral sprain ankle, were randomized into two intervention groups, Concentric group (CG) and Eccentric group (EG). In addition, a control group consisting of 10 healthy subjects with no ankle sprain history and similar demographics are included.
       
      The two interventions group underwent the same physical therapy treatment with the aim to reduce swelling of the ankle up to seven sessions. These treatments include draining the oedema, physiotherapy and retraining the range of motion. After the seventh session, the subjects would be subdivided into CG and EG to the twelve session. The subjects carried out 5 sets of 10 repetitions with two minutes interval on their respective concentric and eccentric strengthening of the ankle evertor muscles, followed by the same ankle proprioception training on a Freeman plate.
       
      The subjects were tested with isokinetic dynamometer with their peak torque measured during pre treatment, on the sixth session and post treatment. The measurements were peak torques in the concentric and eccentric modes; ankle strength deficits, expressed as percentages of the healthy ankle values recorded in the concentric and eccentric modes; ratios between concentric/eccentric values.
       
      Results showed that subjects in the eccentric group have ankle evertor muscles strength significantly greater but concentric group has significant deficits in both concentric and eccentric movement. This means that eccentric rehabilitation can help to restore the strength of the injured ankle evertor muscles which is crucial for better ankle stability. With better ankle stability, the incidence of recurrent ankle sprain will be reduced significantly.
