PRIISM Golf「身体から診るゴルフ」という新しい取り方です。人間は筋骨格的、運動神経的、感覚統合的、性格的にも特性は一人一人異なります。そうした違いを身体の専門家(医療従事者)の立場から分析し、その方に最適なスイングの方向性、トレーニングの仕方、怪我予防対策

Origin of the name and concept of PRIISM Golf, “Golf from the body’s perspective”

The word “prism” means to deflect or change the direction of light (polarization), and the name “PRIISM Golf” was given with the aim of looking at golf from a different angle than the conventional viewpoint. PRIISM Golf is a completely different approach to golf from the new perspective of “Golf from the Body’s Perspective” that will benefit all players. Every human being is unique in terms of musculoskeletal, motor, sensory integration, and personality characteristics. The idea is to analyze these differences from the standpoint of a physical specialist (medical professional), and to work with golf coaches, trainers, and medical professionals to create the best swing direction, training methods, and injury prevention measures for that person.

Current approach to golf: Swing Theory

Golf seminar at NYC

The traditional approach to golf focuses on the “swing”. Therefore, the swing theories of active professionals and the instructors who teach them are taken as the latest swing theories and are overwritten every year. If each of these theories consistently explains the same thing in different ways, that is fine, but sometimes theory A and theory B are fundamentally different ideas.
As background on why these discrepancies arise, many professional golfers and coaches tend to think that what they feel and can do, others can do. But that is not true. As the saying goes, “Great players don’t make great coaches,” and the problems of those who can’t do something are difficult for those who can do it to understand.
Therefore, new theories are not necessarily suitable for all players and can be counterproductive. Especially in these days of information chaos, we receive all kinds of information from Youtube, websites, magazines, etc. By taking in information that doesn’t suit you, you may end up being bad at it, or even get injured. In my clinic, I see many people who have become poor players or suffered injuries by taking in information that does not suit them.

Swing theory is important, but there is no one-size-fits-all theory, and PRIISM Golf emphasizes this point, aiming for an approach tailored to individual characteristics.

Golf Injuries: Repetitive Stress Injury

PRIISM Golf: Each body is completely different

1: Genetic factor

  • Each individual human being is unique due to genetic factors (musculoskeletal, cranial nervous, and motor systems).
    • For example, body softness is largely determined by the strength of collagen fibers and the number of muscle fibers. This is something we are born with. Some people are born soft and some are born hard. At the extreme end of the spectrum are those who are morbidly soft, such as Ehlers-Danlos Syndromes EDS. However, at a level that cannot be called pathological, softness and hardness of the body are determined at the genetic level. Inflammability and tissue resistance are also determined to some extent by genetic factors.

2: Environmental factors

  • Environmental factors
    • Diet: It goes without saying that diet influences physical growth and the maintenance of healthy body tissues. Children and adolescents in particular need a balanced diet of nutrients. An inadequate diet not only stunts growth but also increases the risk of chronic health problems. Conversely, overeating problems that lead to obesity can increase stress on joints and increase the risk of injury. In addition, inappropriate drug intake can negatively affect body and brain function. Translated with www.DeepL.com/Translator (free version)
    • Cultural factors: Cultural factors also influence individual differences. I will not go into details here, but I feel that the cultural environment of my environment, born and raised in Japan, is very different from that of my daughters, born and raised in the United States, including their schools. There is no doubt that this will affect their physical and mental formation (e.g., posture).
    • Sports and Activities: Needless to say, the type of sports and activities a child or adolescent engages in during childhood and adolescence will influence his or her later development of motor skills and skeletal structure. While exercise is essential for muscle and bone development, cardiopulmonary function, and the acquisition of motor skills, the ability to achieve these skills varies depending on the type of exercise one engages in. For example, children who study ballet typically have greater flexibility and balance than other children.
    • Injuries: Injuries are a fact of life. No one has ever been injured as a child. Injuries, especially those that occur at a young age, can have a variety of long-term effects, even if the pain is gone and the doctor has diagnosed a complete recovery. This is especially true in childhood. It may change the way sensory-motor integration is achieved, or if the bone is still growing, it may affect bone growth or unconsciously change the way the body shifts its center of gravity by shielding it from pain.

    • There are an infinite number of other environmental factors that influence the formation of an individual’s body, such as the house they live in, the natural environment around them, diseases, the shoes they wear, and their parents’ educational policies.

3: Anatomical, structural, and sensorimotor integration factors

Structure of the foot bone
  • complexity in the human skeletal and muscular system
    • Humans are said to have 206 bones and 260 to 360 joints. In addition, there are said to be 600 to 1,000 muscles that move these joints. Human movement is the result of the operation of such a large number of joints by countless muscles. Even if the movements seem to be the same, the ratio of joints and muscles used differs from person to person. Even the latest humanoid robots are said to have less than 40 joints, so you can see how complex the human movement is.
      Motion analysis, biomechanics, and kinesiology are advancing day by day with technological advances such as accelerometers and optical reflex motion capture systems. However, while these data can analyze the overall macro-movement of the body, they are still far from being able to analyze micro-movements such as the detailed movement of each joint and the use of each muscle.
  • Sensory-motor integrative differences
    • As mentioned above, humans have countless joints and muscles. In addition, cranial nerves control them to move the body. This cranial nervous system is also completely different for each individual. For example, left-handed and right-handed people use their bodies in different ways.
    • Sensory integration is also completely different for each individual. Even when receiving stimuli from the outside world, the way person A feels is different from the way person B feels. For example, even if the same stimulus is applied to the body, some people may feel a pleasant sensation, while others may feel a tickling sensation. Even if the stimuli are the same, the individual sensations will vary depending on how the brain perceives the stimuli. The same is true of vision. Even if the information coming from the eyes and optic nerves is the same, each person’s perception will be different depending on how the brain processes the information. The same can be said for body movements. Even if the same golf address is made, Mr/Mrs A may feel a very forward tilt, but Mr/Mrs. B may feel a backward tilt.
  • Asymmetry of the body
    • From the outside, the body appears symmetrical, but in reality the left and right sides of the body are asymmetrical. For example, in the internal organs, the stomach is on the left, the liver is on the right, the right kidney is higher, the large intestine is clockwise, and so on. The same asymmetry can be seen in the respiratory system, circulatory system, locomotor system, visual system, and so on. Each of these organs has its own responsibilities, functions, and demands. The structural differences between the left and right sides of the body also vary from person to person, and how to control these differences also varies from person to person.


In other words, people differ due to genetic and environmental factors, and have asymmetrical structures. The movement (golf swing) produced by the cranial nervous system using a vast number of joints (bones) cannot be the same for any one person. The sensation of that movement (golf swing) is also unique.

What not to do, “Four principles you shouldn’t in Golf”

At PRIISM Golf, we believe that understanding these individual physical differences and tailoring a golf approach to suit the individual is the best way to learn to swing more efficiently, reduce the chance of injury, and create an effective training plan. Specifically, through physical assessment, we advocate the “Four No’s” of golf: first, try not to do what you should not do. We work from the premise of knowing one’s own physical habits and then following the four prohibitions: 1) do not swing in a way that does not suit your body, 2) do not use clubs that do not suit your body, 3) do not do on the course what your body cannot do, and 4) do not train in a way that does not suit your body.

The Japan Wellness Golf Assocaition (JWGA), a user organization of “the Four No’s in Golf”, is working to achieve a “lifetime of health and play” through the successful implementation of PRIISM Golf.
