The Path to Success - The Double OCD syndrome





Dedicated to my daughter Aabha, my nephew Yash and all my little friends and upcoming Physios who are the future of this great country.

“You are what you choose to be”, said Hogarth Hughes to the Iron Giant with a heart (From the movie Iron Giant). But is it really that simple. We always say how much life has been unfair to us all, how we so rightly deserved something but never got that reward. But is life so unfair to us at all? And if it is, what did we do to deserve something so bad???



Well, the problem is that we have been trained to crib about everything in life. We have seen our parents, families, friends, and neighbours, practically everyone around crib so much that we start believing in an unjust, unfair, miserable life. We believe that there are only selective people who have got the luck to be successful and we are the unsuccessful lot. Well, the truth is that success is not a physical domain. It is a state of the mind. Success is based on how well we can understand the Double OCD syndrome.

Most of us understand OCD syndrome as the Obsessive Compulsive Disorder Syndrome, which is a behavioural challenge of doing something repeatedly. It is generally taken in a negative term.
The Double OCD syndrome we are talking about is the Opportunity, Challenges, Determination, Option, Choice and Decision syndrome. This is not any medical condition. It is just how we look at life in its vivid ways.



We all feel that life never give us an opportunity. Well, the fact is that we are given abundance of opportunities, just that we did not realise them. I remember the story of a devotee trapped in floods who was waiting for God to rescue him. He refused to take help from a passing car who offered to help him. As the waters rose, a rescue boat came. He refused their help saying that God will save him. When the waters rose to drown him, a rescue helicopter came to take him. He refused saying God will save him and alas, he drowned. In heaven, he asked God why such an injustice was done on such a faithful devotee. God replied, child I had given you the opportunities by sending the car, the boat and the helicopter. I was fair and just to you. So is life really so complicated? We don’t fail because we don’t get the opportunities, we fail because we do not realise them. Successful people look at opportunities in every aspect. They look at every challenge as a means to perceive things in a new way. They are successful only because they look at everything with a different perspective. Thus success in always a state of mind which helps us realise the best solutions in the worst case scenario.




Challenges are a part of life. In fact, challenge is a stimulus for growth, a stimulus for inventions and innovations. But many of us are too safe in our cosy zone and thus we resist change. When I read the book ‘Who moved my cheese’ by Spencer Johnson, there was a beautiful realisation of the need to understand this change. Heraclitus had rightly said, “Change is the only constant of life”. Even a stream has to flow, gushing through rocks and pebbles to boulders to become a mighty river. A stagnant pond is also of no use for sustaining life within itself. Challenges help us understand the force, direction and magnitude of this change. Thus, by simple law of physics, challenge is a vector quantity and thus can always be used for gaining mechanical advantage, provided we can determine the direction to success.




There are many challenges that we encounter in life. Everybody’s childhood may be filled with challenges, from learning to earning. But understanding the way in which we can use these challenges helps us understand the way to achievement. My mother’s accident in my 11th standard introduced me not just to become self sufficient and self determined, but it also introduced me to the profession of Physiotherapy, which invariably became my stepping stone to success.




Once we have learned to change our perspective to the opportunities and give direction to the challenges, what we need is the determination to do it. Salman’s famous dialogue is the best example, ‘Ek baar jo maine commitment kar di toh mei apne aap ki bhi nahi sunta’ (Once I am committed to something, I don’t even listen to my own self). Determination is the key element to success cause if you are not determined; you may get short term benefits, but will lose on the long term gains. We had seen a wonderful video on 'The Compound Effect' by Darren Hardy. Whatever changes are to be brought about can never be seen unless you are determined with it. It can be as simple as losing your weight. If you workout for a month or two, there may be short term benefits. But to achieve those six packs, there’s always a compound effect of determination to do it, no matter what! There is no short cut to success and only the determined walk through the path to achieve their goals.




Life gives us options in every simple opportunity presented to us. In the earlier case, God had given many opportunities to the devotee. What he lacked was not just the understanding of the opportunities, but the lack of understanding the options and making a choice. We all understand the power of options in many physical dimensions of life, options while shopping, voting, attempting exams etc. But it is much difficult to understand the options in the factors of life. Although we interchange the words options and choice, choice is the action which we take on the situations called as options. We choose to act morally or immorally on the option of the moral decision, to react rationally or irrationally in a confounding situation. The choice that we make on the options of our life is called as our judgement. It is easy to pocket a wallet full of money that you find on the road. But to return it to its owner is a choice based on the options that you had. It is easy to be unfaithful to a person, but to love, cherish and care for that person forever is a choice that you take on the options that you have. This pair of options and choice is what makes us a human.





And finally, the judgemental call that you take is your decision. It is a virtue to act on a strong foundation and firm belief that should imminently lead to good, moral and noble character. Thus success is not only a mental factor, it is a spiritual factor as well. There may be someone who looks at robbery or murder as an opportunity to be successful, does an excellent planning to overcome the challenges and is determined to commit the crime. Only a noble character will realise the options to commit or not to commit the crime, to be an accomplice or not and will take a rational choice and a judgemental decision to act in good faith. Options, choice and decisions help us understand the consequences of the opportunities, challenges and determinations. They are the situations that make a twin brother a police officer and the other a criminal. What one saw as an opportunity to learn, a challenge to progress and determination to succeed with an option to choose the correct decision was perceived by the other as an opportunity to commit crime to overcome the challenge of poverty and the determination to become a master criminal with an option to choose the wrong decision. A person became a drunkard because his father was a drunkard. Another chooses to start an alcohol de-addiction centre because his father was a drunkard. Thus, it is a judgement in the same situation which makes us good or bad, loved or hated.



The path to success may seem difficult to us all. But preparing the mind to be willingly successful and the heart to be morally successful  is extremely important. Success can only be achieved when we understand the Double OCD syndrome and not only morale our thoughts, but also make our thoughts moral.

Scapular Considerations in Racquet Sports



Injuries in the Racquet Sports
  • Racquet sports, especially lawn tennis and badminton have been gaining popularity in Asian countries like India.
  • With this increase in popularity, the injury rate in the sport has also increased.
  • The injury rate in tennis varies from 0.04 injuries/1000 hours to 21.5 injuries/1000 hours
    • Pluim BM, Staal JB (2006)
  • Different overhead sports show different characteristics, but have similar movement patterns.
  • In each, the dominant upper limb is subjected to repeated overhead movements.
    • Torres RR, Gomes JL (2009), Wilk KE, Meister K (2002)



Racquet Sports – Biomechanics

  • The mechanics of an overhead stroke or serve in racquet sports are similar to that of an overhead throw, wherein the shoulder has to be lax enough to allow the extra degrees of external rotation necessary for an adequate serve and at the same time has to be stable enough to prevent any subluxations.
    • Craig A. (1995)
  • This delicate balance between mobility and stability is referred to as ‘throwers paradox’ and if compromised, can lead to injury.
    • Wilk KE, Meister K (2002)

  • A racquet serve/stroke is a combination of true gleno-humeral rotation, trunk hyperextension and scapulo-thoracic motion.
  • The cocking phase maintains the dominant arm in 90° abduction and external rotation which reaches a maximum of 172° to 180° during the late cocking phase.
    • Fleisig GS, Barrentine SW (1996), Fleisig G, Nicholls R (2003), van der Hoeven H, Kibler WB. (2006)
  • It ends with internal rotation and forward flexion of the dominant shoulder along with upper torso and pelvic rotation during the follow through phase.
    • Jason A. (2007) 

The GIRD:

  • Each phase places an asymmetric load between the two shoulders, with the dominant shoulder exposed to maximum stress. Jason A. (2007) 
  • Studies have shown a significant difference in the gleno-humeral internal rotation range of motion between dominant and non-dominant shoulders of overhead sport players.
    • Shimpi AP, Shah B (2015). Shah N, Shimpi AP (2016)
  • This is defined as ‘Gleno-humeral internal rotation deficit’ (GIRD), which is the loss in degrees of the gleno-humeral internal rotation of the throwing shoulder compared with the non-throwing shoulder.
    • Burkhart SS, Morgan CD, Kibler WB. (2003)
  • An accepted level of GIRD is less than 20° deficit of gleno-humeral internal rotation or less than 10% deficit of the total rotation seen in throwing shoulder as compared to the non-throwing shoulder.
    • Burkhart SS, Morgan CD, Kibler WB. (2003)
  • The scapula provides a stable base to the movement of humeral head during an overhead motion. The stability of the scapula becomes important in these movement patterns. Jason A. (2007) 


SICK Scapula….
  • An asymmetry develops in the scapular posture of overhead athletes like tennis players, where the dominant scapula is more protracted than the non-dominant side.
    • Oyama S, Myers JB (2008). Shimpi AP, Shah B (2015)
  • The acronym SICK scapula (scapular malposition, inferior medial border prominence, coracoid pain and malposition and dyskinesis) is used to describe this asymmetry of scapula.
    • Burkhart SS, Morgan CD, Kibler WB  (2003)
  • This asymmetry is accentuated in unilateral overhead athletes who use their dominant shoulder repetitively in a forceful manner.
    • Oyama S, Myers JB (2008). Shimpi AP, Shah B (2015)
  • Many authors suggest that this increased scapular protraction along with GIRD, increases the likelihood of shoulder injuries in these players.
    • Wilk KE, Obma P (2009). Thomas SJ, Swanik KA (2010)
  • Shoulder girdle injuries account for 17.27% in racquet players with 43.4% of elite tennis players presenting with scapular dyskinesia.
    • Borsa PA, Laudner KG (2008). Kondric M, Matkovic BR (2011)
  • Studies have also shown a positive association between a dyskinetic scapula with posterior shoulder tightness and GIRD in the dominant arm of overhead players.  Laudner KG, Moline MT (2010). McClure P, Greenberg E (2012)
  • During the follow through phase, the scapula has to protract around the thoracic wall in order to help dissipate the energy.
    • Kibler WB. (1991). Voight ML, Thomson BC. (2000)
  • In the presence of considerable GIRD, the players have to bring about increased scapular protraction to compensate for the reduced internal rotation in order to maintain the velocity of the overhead stroke.
    • Thomas SJ, Swanik KA (2010). Shimpi AP, Shah B (2015)
  • With time, this continuous stress causes soft tissue adaptations and leads to weakness of the scapular stabilizers, mainly the lower fibres of rhomboids causing an upward rotation.
    • Thomas SJ, Swanik KA (2010). Shimpi AP, Shah B (2015)
  • Thus, the scapula cannot provide a stable base of support for the rotator cuff to function, which reduces its efficiency and increases stress on the static restraints of the dominant shoulder. Thomas SJ, Swanik KA (2010)

  • So, rather than compressing the humeral head into the glenoid fossa, the rotator cuff pulls the scapula upward and laterally resulting in greater scapular protraction and external rotation.
    • Kibler WB. 1998. Shimpi AP, Shah B (2015). Shah N, Shimpi AP (2016)

Why Scapular Perspective?
  • During the follow through phase of an overhead motion, the shoulder joint is subjected to distractive forces of up to 750N which is mainly resisted by the postero-inferior capsule.
    • van der Hoeven H, Kibler WB. (2006)
  • With repetitive loading, the posterior capsule is said to undergo micro trauma causing hypertrophy and increased fibroblastic activity during the healing process, leading to contracture and thickening of the capsule. Thomas SJ, Swanik KA (2010)
  • This reduces the capsular pliability causing restriction of internal rotation, extension and horizontal adduction.
    • van der Hoeven H, Kibler WB. (2006). Thomas SJ, Swanik KA (2010). Shimpi AP, Shah B (2015)

  • A posterior capsule stretching program incorporated in the rehabilitation and training of overhead players is reported to reduce the incidence of GIRD.

  • It also reduces the incidence of shoulder injuries like Superior Labrum Anterior Posterior (SLAP) lesions in these players.
    • Burkhart SS, Morgan CD, Kibler WB (2003)
  • Arthroscopic studies have also shown increased thickness and hypertrophy of capsule in the postero-inferior recess of dominant arm of throwers and its positive association with GIRD, external rotation and scapular upward rotation. Thomas SJ, Swanik CB (2011)
  • Studies have shown that for a 4° decrease in internal rotation, there is 1cm decrease in horizontal adduction, which is an indicator of posterior capsule tightness.
    • Torres RR, Gomes JL (2009)
  • Studies also showed a significant increase in the external rotation of the dominant shoulder compared to non-dominant side in racquet players and when compared to dominant side of non-racquet players.
    • Shimpi AP, Shah B (2015)
  • One of the causes can be attributed to the contracted or shortened posterior band of the inferior gleno humeral ligament (IGHL) which primarily provides restraint to further movement in position of maximum abduction and external rotation during late cocking phase. Burkhart SS, Morgan CD, Kibler WB. (2003)
  • It prevents posterior migration of humeral head, thus centering it in the glenoid fossa allowing a normal arc of movement.
    • van der Hoeven H, Kibler WB  (2006)
  • Arthroscopic findings in overhead players show contractures and thickening in the zone of the posterior band of IGHL.
    • van der Hoeven H, Kibler WB  (2006)

  • The tethered posterior band draws the humeral head postero-superiorly to a new point of rotation on the glenoid, thus causing an abnormal increase in the external rotation due to easier clearance of the greater tuberosity.
    • van der Hoeven H, Kibler WB  (2006)
  • The postero-superior migration of humeral head also reduces the cam effect of the humeral head and antero-inferior humeral calcar on the antero-inferior capsule leading to redundancy in the antero-inferior capsule, allowing hyper external rotation of the dominant arm. Burkhart SS, Morgan CD, Kibler WB. (2003). Burkhart SS (2007)

  • Another explanation for the increased external rotation can be possibly attributed to increased humeral retroversion which is a common finding in players playing overhead sports.
    • Kibler WB, Sciascia A (2012)
  •  This change in the humeral head causes a shift in the arc of rotation of the dominant shoulder favoring external rotation.
    • Tokish JM, Curtin MS (2008)
  • However, the studies suggest that the total arc of rotation remains the same, as any increase in the external rotation will require a corresponding decrease in the internal rotation, which will be permanent. Lintner D, Mayol M (2007)

  • There exists presence of abnormal scapular resting position in asymptomatic racquet players on the dominant side in the form of scapular external rotation and elevation on the dominant side as compared to their non-dominant side.
  • There also exists presence of gleno-humeral movement dysfunction in the form of reduced internal rotation, extension and adduction and gain in external rotation on the dominant side.
  • A comparison between symptomatic and asymptomatic players could help determine the pathological threshold for injury predisposition.
  • ROM and scapular resting position can be used as a screening tool for injury prevention in overhead racquet players.
    • Shimpi AP, Shah B (2015). Shah N, Shimpi AP (2016)

Advanced Training
  • Most important is to prepare the athlete for a long term, not just for the coming season.
    • Nyland J (2010)
  • Functional exercises simulating the athletes role and Sports Specific Scapular training is extremely important.
  • This helps in gaining an excellent neuromuscular control and functioning.
  • More useful in establishing athletes self efficacy and confidence as movements closely resemble the athletes sports specific movements.
    • Nyland J (2013)
  • Functional training can be achieved by training the athlete in a sports simulation by:
  • A. Uni-planar training the protractors.

  • B. Uni-planar training of the retractors.

  • C. Bi-planar motion training

  • D. Multi-planar motion training.

  • E. Simulation of the game with resistive training
    • Nyland J (2011)

  • Further enhancement can be obtained by using unstable surface like the BOSU for bodily challenges and further enhancement.
    • Wankhede N, Shimpi A (Hypothesis)
  • This can be challenged using:
  • A. Strength training on BOSU

  • B. Limb and trunk challenges

  • C. Focused stability challenge

  • D. Hit and serve challenges.


Summary
  • Injured overhead athletes may display more asymmetry than healthy overhead athletes, and there may be a pathologic threshold for scapular posture asymmetry at which an asymmetry becomes problematic. Shimpi AP, Shah B (2015)
  • Need of specific stretching and strengthening as a part of the pre-season training of racquet athletes to address muscular imbalances to provide optimum scapular and gleno-humeral stability to the shoulder to endure the demands of the game. Nyland J (2013)

  • Need for advanced training to prepare the athlete in prevention of injuries and correct the problems before they become real problems for the athletes. Wankhede N, Shimpi A (Hypothesis)
