The Premise: It is desirable to consistently hit the ball in the center of the club face.
Consistent Center Impact Spots
The Problem: Testing shows that hitting the ball consistently in the center of the club face is not easily achieved even by PGA tour players.
Not uncommon Tour Player results; impacts all over the driver face.
The Solution: The revolutionary Grooved Golf Grip will "cause" a golfer with a decent swing and a properly fitted club to hit the ball more consistently towards the center of the club face. Notice we said, "cause". This revolutionary performance enhancing grip requires no lessons or training to improve the center hits on the club face. We proved it with PGA tour player testing. (link to below)
Revolutionary Grooved Golf Grip
The "Cause": The "cause" requires an explanation. The explanation necessitates understanding how the human body functions and biofeedback.
The Golf Swing, Medically Speaking: The golf swing, written in medical terms, looks like this: Golf is dependent upon the player's innate proprioception, spatial relationships and neurosensory transmission, central nervous system interpretation, psychomotor skills and motor memory execution.
Medically speaking, the golf swing sounds impossible. Furthermore, it happens so fast, in a matter of seconds. No wonder golf is difficult. There is no time to think about anything. In fact, it is best if the golfer does not think about anything except visualizing the best swing he can put on the ball. The execution must have a foundation of solid principles built in prior practice. In other words, he/she must play by feel. Does all this happen without consciously feeling anything? Yes, because there is no time in the split second of the stroke to think or to focus upon any specific feeling! At best the player might capture a single swing thought. If the player tries two or more swing thoughts, malfunction sets in. All the biological data must be collected instantaneously in the player's psychomotor system and executed spontaneously via the musculoskeletal system to complete the stroke.
Medical Explanation: Understanding how this revolutionary patented, USGA conforming Grooved Golf Grip works requires a medical term briefing in neuroanatomy and neurophysiology.
A Neuroanatomy Lesson: Our fingers are more sensitive than the palm of our hand and much more sensitive than our back. The reason is that there are more nerve endings per square inch in the skin of the fingers than the palm or the back. The patented and registered, trademarked Grooved Golf Grip exploits the normal neuroanatomy of the fingers and hands.
A Neurophysiology Lesson: The human hand naturally has ability to determine spatial relationships and 3-dimensional geometry. It does not require schooling or a physical therapy lesion for a person to reach into their pocket and pull out a car key rather than the adjacent cell phone. Humans have a second nature for discerning the shapes of three dimensional geometric objects. This occurs instinctively by the neurological connection to the brain and back again to the muscles of the upper extremity.
Proprioception: This is the normal body function that intuitively knows where it is in space. For instance, you can close your eyes and move your finger to touch your nose, your ear and even move your right foot so your heel is placed on top of your left knee. No lessons necessary to accomplish these feats. Every good golfer has a high level of proprioception skills.
Back to the Golf Shot: The golfer utilizes his/her normal neuroanatomy, neurophysiology and proprioception to hit the golf ball in the desired direction and distance.
There is Help for the Golfer: This USGA conforming grip with US Patented longitudinal grooves enhances the golfer's perception of where the golf club is in space. It is intuitive. It does not require instruction or physical therapy.

Dermal Impression: Most golf grips make some kind of dermal impression. The human body reads intuitively the dermal impression on the skin of the fingers and hands when the golf grip is grasped. However, only the Grooved Golf Grip has perceptible longitudinal grooves in each quadrant. These grooves by their size and position make an imprint at the highest level of human recognition and perception. If they were smaller than 2 mm wide, it would be below the human perception threshold.
Dermal impression created on the golfer's thumb by sinking into the groove on the grip. In this case it is the left hand when the groove is in the neutral position and the thumb is on top of the shaft.
Three Dimensional Shape Perception: This dermal impression is a miniature of the geometric three dimensional shape of the golf club shaft that is registered in the golfer's neurosensory apparatus. Neurosensory wise, the golfer becomes one with the golf club.
Spatial relationship: The longitudinal dermal impression which is in alignment with the shaft, instantaneously telegraphs to the player's brain the position of the golf club shaft in space. No lessons are required.
What does this means to the Golfer? It means he/she is connected, even imbedded intimately to the golf club by this dermal imprint created by the Grooved Golf Grip. The golfer grips the Grooved Golf Grip resulting in multiple longitudinal dermal impressions on the player's fingers and hands. It does not matter where the golfer places their hands on the grip, there will be dermal impressions.
Demonstration of Dermal Impression
We want feel to be spontaneous and intuitive, resulting in better club face impacts for better and more enjoyable golf. See "The Technology of Feel" of the Grooved Golf Grip. (link to below)
Added Benefits of the Grooved Golf Grip:
No Slipping: The imbedding of the golfer's skin into the grooves results in resistance to torque or slipping of the hands.
All Weather Grip: The all rubber material is water resistant and stays dry in wet weather.

Features of the Grooved Golf Grip
Longitudinal Grooves: Unlike conventional golf grips, the Grooved Golf Grip has longitudinal orientation to its grooves. They are not oblique as seen with conventional grooves. This feature eliminates any brain confusing geometries on position of the golf club in space. The remainder of the grip surface has minimal texture that is below the threshold of perception, thereby removing easily palpable conflicting features.
Tour Proven: Extensive testing has been performed with the cooperation of PGA tour players. During preliminary testing, various players were asked to tell us how this new grip feels. They were not told about the features of the grip. They discussed everything but the grip while saying the test club's head geometry was not to their liking. They often complained the shaft was too weak or not to their specifications. Occasionally, a player recognized something different about the grip, but they were not sure. When asked about feel, one summarized what others expressed in other ways, "It feels like an extension of my arms and body." We then revealed the nature of the grip. Unprejudiced and unbiased, the participating players were obviously influenced by the subliminal neurological input from the alignment biofeedback imprint on their fingers and hands that yielded such better impact spots on the club face.

Grooved Driver/Iron Grip CHOICES
NEW FOR 2014 SEASON
This grip is softer with a durometer of 50. It is lighter at 50 ±2 grams. This grip replicates the specifications of the traditional driver/iron grip while preserving the USGA conforming grooves for breakthrough performance. It has the feel of a "velvet" grip. There are longitudinal grooves in each quadrant. The butt design is such that provides a visual guide for assembly to the shaft and orientation of the longitudinal grooves. ** Also order laser alignment tool to insure proper installation.
All of our testing was performed with the top line at neutral position. The laser alignment instrument has a fin or keel to make sure the grooves good down the shaft to the hosel, not the club face leading edge. The later may vary from club to club.
We only tested the neutral grooved position. It does not matter where the player places their hands or thumbs. There are 4 grooves and the hands will feel them somewhere.
The angled lines on the butt provide a guide to facilitate the straight down the middle of the shaft application of the top groove. If the player wants the groove slightly right or left to accommodate his/her particular grip so that their thumb of their upper hand is under the groove when the club is at the top of the back swing.

The Technology of Feel
The Grooved Golf Grip is a revolutionary game improvement golf grip. The introduction of longitudinally oriented miniature sized grooves has provided a seamless neurologically perceptive connection between the golfer and the club. The orientation of the miniature grooves are perpendicular to the forces that would produce unwanted shaft or club face twisting. They provide a firm hold that controls shaft torque.
Why the name "Synapse" and what is "Synapse"?
The term "synapse" was coined in 1897 by the English physiologist Charles Sherrington. It was fashioned from the Greek word "synaptein" meaning to fasten together. In neuroanatomy, a synapse is the site of functional apposition between neurons, where an impulse (information) is transmitted from one to another, usually by a chemical neurotransmitter across the gap as there is no physical continuity.
Diagram of three synapses. Nerve impulse is indicated by arrows, showing that the direction of passage is from the terminal arborization (TA) or nerve endings of the axon of one neuron to the dendrites (D) of another neuron.
The word "synapse" is used in describing the Grooved Golf Grip in that there is no physical continuity between the player's skin and the rubber golf grip. The player's skin is in intimate contact with the golf grip's groove allowing the transfer of information from the golf club to the player's neuromuscular system. This intimate contact for controlling torque gives the golfer a high level of shaft position and club face direction at impact.
The concept is protected by at least one of US Patent No. 7637821, 7794332, 8062147, 8092317, and additional patents pending.
The various Grooved grips are USGA conforming.
Dr. Lanny was the first generation Grooved Golf Grip
A medical doctor upon hearing the grip's name, Synapse®, for the first time, concluded; "Oh, there must be electronics in the grip". No, the electronics are in you, the golfer. "I get it" he proclaimed. "I get it. It works because of how the body's electronics work." He got it.
WHO IS BEHIND THIS DEVELOPMENT?
Lanny L. Johnson, M.D.
Howard Twitty, PGA Tour Player
This revolutionary grooved golf grip was invented by Dr. Johnson and developed in conjunction with Howard Twitty.
Expectations: The Grooved Golf Grip provides a true innovation for golf grips; a game improvement and enjoyment feature. Testing shows most golfers, independent of ability level showed an impact pattern of the driver face that was more compact and closer to the center of the face than with the control driver. This should produce a longer and more accurate ball flight due to the consistent center hit on the face. This contention was confirmed with a pilot study with PGA tour players. The performance was better with 90% of players tested with a golf club they had never seen with a Grooved Golf Grip than a driver perfectly fitted to a PGA Tour player by their sponsoring manufacturer that does not have the Grooved grip. It will not correct a flawed golf swing no matter the level of expertise nor instantaneously lower one's handicap. However, early experience has shown surprisingly improvement in consistency, distance and direction with practice and play in a few weeks.
Potential Adverse Reactions: There have been none related to the use of the grip. The size of the grooves although large enough for a neurological imprint have shown no physical adverse effect on the player's hands. In the practice of medicine we hold to the old adage of "do no harm". This grip does not do any harm.
PGA TOUR PLAYER PILOT STUDY
A pilot study was performed on PGA tour players in attempt to establish a proof of principle.
The hypothesis was that a consistent center hit on a driver would result in a longer and straighter drive and more consistently.
PGA tour players were solicited to be involved in the test on the driving range on the days prior to their respective tournament. After they had hit though all their clubs and had finished with their driver, they were asked if they would participate in a test by hitting first their driver 5 times and then the test driver 5 times. An impact paper with adhesive backing was placed the face of each driver. The player was to hit successive shots, but not to look at the impact spots until the test was concluded. The player then did the same with the test driver; a 15 year old Bridgestone 9.5 degree J33R head with a Graphite design PM 702s prototype stiff graphite composite shaft with the Grooved Golf Grip.
Only one PGA regular tour player tested consistently hit his driver in the center of the face. The following illustration shows the impact spots on his driver on the left and the trial driver on the right.
Testing of players immediately prior to a tournament provided information to compare where the player made impact and their driving statistics in the following days in the tournament. It was then of interest to see how well he did in the tournament. This player shot 5 under and finished 12th place at Riviera in 2011. His statistics showed he was tied for 5th in driving accuracy and 4th in driving distance. (See below copied from public domain of PGA Tour Internet page)

|* Ranks are computed at the end of each round.|
This International player's testing results are one of many examples supporting our hypothesis that hitting consistently in the middle of the driver face results in longer more accurate drives.
Many other players were tested in a similar manner. The example below is from a Champion Tour player.
The test was performed with paper impact tape on the driver face. The pattern on the left was that five hits with the driver previously perfectly fit to him by his sponsoring manufacturer. The impact spots on the right were collected with 5 hits with a test driver with the Grooved Golf Grip which was never in the player's hands prior to this test. This player had 2 PGA regular tour wins. He was presently 61st in total driving on the Champion's Tour. With the pattern on the left above he was T73 in accuracy and 17th in driving distance. He obviously has a fast club head speed for distance, but hitting impacts all over the driver's face results in poor accuracy.
Tour Player Testing: The following links show many convincing proofs from PGA Tour players.
Other studies: We have examined how the grooved grip influences the impact site on the driver in a couple ways. One way was to have the same head and identical shafts; one with and one without the grooved grip. The improvement was seen with the grooved grip.
Another method was to have the player hit first with their driver, then the test driver, followed by applying the grooved grip to their driver. The following is one example of amateur golfers.
|17 year old high school golfer, just fitted with a driver: 6.2, extra stiff shaft and 9.5 loft Taylor Made driver. He drives over 300 yards. He hit his driver. Then without practice swing he hit the test driver 5 times. He then had the 4 grooved grip placed on his driver. After waiting for 40 minutes until the grip was secure he hit his driver 5 times.

His Driver 4 Grooved Grip
|The results show he had scattered impact spots on driver face with his driver. He improved in location and compaction of the impact spots with Test driver. However, just 40 minutes later or within one hour time without any practice the impacts spots on his driver with the four grooved grips showed marked improvement in location and consistency.
HOW AND WHY THE GROOVED GRIP WORKS
It is how the human body works. Some very good players, PGA professionals included, said they do not want to know how it works, just as long as it works. We do make it clear that it is not the traditional explanation of how the golf club works, but tell them this is related to how the human body works.
Others want a complete technical explanation. This requires an explanation in medical terms. It is how the human body works. There are three normal human body functions; sensibility, proprioception, and neuro-muscular memory.
This explanation requires that we state the obvious. The golf club does not know where it is in space. Only the golfer can discern where the club is while it is moving through space. The golfer's connection to the club is what he/she feels through the golf club's grip. The connection between the player and the golf club is not a remote wireless, but requires an intimate connection. This connection must be intimate, solid, seamless and continuous between the player's hands and the golf club grip from the time the golfer takes aim and continues through impact. With the Grooved Golf Grip it does not matter where the player places his hands, the torque control benefit will be there. The enhanced feel will be there. The longitudinal grooves literally capture that golfer's skin securely to the golf grip.
However, feel is a difficult term to define when referencing a golf swing. The following description is The Technology of Feel as it applies to golf.
THE TECHNOLOGY OF FEEL
Golf is a game played by feel, while being supported by new advances in technology every year. Professional golfers will tell you they play by feel while having uniformly the best techniques supported by the latest technology. So there is a dichotomy in golf. Is it feel or technology? Technology is easily understood and or explained. Feel is a more illusive term to define. It is so personal. Defining feel is like quickly and completely describing a puff of smoke flowing through a room.
However, during the development of the Grooved Golf Grip the definition of feel became more apparent. Simply put, one could say it is biofeedback. That is true, but the term is so frequently used it is almost trite. The following description of the human biological factors that in combination result in feel has lead us to understand the technology is very much a part of feel. In fact, read on to better understand The Technology of Feel.
Sensibility or The Ability to Sense or Feel: The human finger tips and the lips have the most nerve endings per square inch of anywhere in the body. Therefore these areas have the highest level of sensory perception or sensibility. The finger tips can be thought of as high level neurological information collectors. The golfer's hands "feel" were the golf club is in space.
In medical terms, this high level of perception is measured by what is known as 2 point discrimination. It is the body's ability to determine if it is being touched with one or two pin pricks at successive narrower distances. The norm for humans to discern 1 or 2 pin pricks on the finger tips is a width of 2-4 millimeters. On the back of the shoulder it may be 100-130 millimeters since there are fewer nerve endings in the skin of the back than on the finger tips or our lips.
Typical calipers used in clinical testing for sensory status.
Based upon these known human findings, the Grooved Golf Grip has patented 2 mm wide and 1 mm deep longitudinal channels. These dimensions provide the highest level of sensibility. Most humans cannot perceive a structure of lesser dimensions.
When the player grasps the Grooved Golf Grip only the player's skin sinks into the longitudinal channels. The grooves are no different than any other golf grip; i.e. the grooves on the traditional wrapped grip. The difference is the longitudinal physical orientation of the grooves. There is no corresponding grip geometry on the Grooved Golf Grip to any anatomical structure on the hand; i.e. finger, thumb, etc.
The impression created on the player's thumb or fingers as they sink into the grooves on the Grooved Golf Grip. There are no other conflicting geometric structures on the grip that are easily palpable or discernable, since they are all less than 2.0 mm in width.
This intimate physical between the golfer's skin and the longitudinal grooves in the grip has two other functions.
Anti-rotation: The intimate integration of the locking of the player's skin and the grip prevents rotation of the club in the player's hands at impact, even with miss hits off the toe. Thereby, torque is controlled.
Palpable Cognitive Recognition of 3 Dimensional Objects: A common test used to test a patient's sensory cognitive skill is to place various small objects in a black bag. In the bag are several items of different shapes; a marble, a dime, a penny, a tooth pick, and a safety pin.
Since this is golf oriented testing, we placed a golf ball, a tee, a quarter, a dime, a ball marker, a divot repair tool and a pencil in the bag.
The patient is asked to blindly identify an object in the bag (a pencil) and then pull it out for confirmation.
The golfer, with normal sensation and cognizance, was asked to reach into the bag and remove the pencil. It was successfully identified by its shape, size and texture as well as the physical difference from the other objects.
A normal person can easily identify the objects felt by their hand without looking. The human hand has ability to perceive and distinguish various three dimensional shapes.
The relevance of this medical test to the longitudinal grooved golf grip is that the superficial imprint on the skin of the player's hand and fingers. This shape replicates the golf club shaft. Importantly, the three dimension imprint on the player's hand is in the same spatial relationship as the golf club shaft. Therefore, without any cognitive intention, the player perceives where the club shaft is in space to an extent not otherwise available to their nervous system. The golfer does not need to be consciously thinking of this feature of the DrLanny/Grooved grip, it is automatic. The golfer's psychomotor system is now functioning as an extension of the golf club via the Grooved Grip.
The high level of sensibility and that of cognitive discrimination of the Grooved grip provides a sensory input to perceive and instantaneously know where the golf club shaft is in space and thereby direct the golf club's movement in space. That is the point where the normal human function of proprioception takes over.
Proprioception is a medical term. It is defined as the unconscious perception of movement and spatial orientation arising from stimuli within the body itself. In humans, these stimuli are detected by nerves within the body itself, i.e. joints, tendons, muscles. The semicircular canals of the inner ear also participate.
A practical demonstration of proprioception is the ability to close one's eyes and touch your index fingers of both hands together without looking. You can do the same with little fingers, index to the point of the elbow, put both index fingers in your ears, and put your right heel on your left knee cap. All these moves are made without looking. Why is this? It is because by design and experience your body knows where it is in space.
Remember, the golf club does not know were it is in space. There must be a connection at a high level of sensory perception which the Grooved Grip provides.
NeuroMuscle Memory: The human body has a wonderful way of remembering past movements. This is often referred to as muscle memory although the proprioception is registered not only in the muscles but in and around the joints. As mentioned above the golfer gets the muscle memory from the sensations recorded in the hands, coupled with the registration of where the entire body was in space. After that information is in the memory bank, the information is sent back through the body to the hands so the muscles then are able to repeat the recorded performance to be transferred to the golf club via the grip.
In the familiar computer terms one must have an adequate hard drive, sufficient memory, and lots of RAM to be a good golfer, plus the solid, seamless, and continuous connection to the golf club grip which simulates the position of the golf club shaft. Technology is supporting the feel.
Very little has changed over the years with golf grips, until now. Until now, the technology has focused on the material; leather, rubber or various synthetics. The annual "innovations" have been limited to material consistency, weight and changes in the color de jour. The golf grip's potential to exploit the dynamic connection (the synapse) between the player and the golf club has been ignored, until now; until the Dr. Lanny Grooved Golf Grip.
"A Better grip for the better golfer,
and for golfers who want to get better."
