Hand Assessment Chart: A palm reading profile via 36 hand features!

leave a comment »

Aristole described: ‘the hand is the organ of the organs’. Later, in medical science the hand became recognized to represent the most differentiated external part of the body. This implicates that an assessment of the hand is a rather complex (arbitrary) task. In order to simplify the task an ‘assessment chart’ was developed based on the principles described by Multi-Perspective Palm Reading.

The ‘assessment chart’ (see above) presents an overview of 36 key-features of the hand, the significance of all individual hand markers involved has been confirmed in scientific studies – though the significance of course varies and depends on the theme for which a hand feature is used to make a (hand) assessment.

The chart is divided in 8 sections, one for each of the 7 hand dimensions (including: dermatoglyphics, finger length, lines, motorics, nails, shape & skin) – NOTICE: the dimension ‘dermatoglyphics’ is divided in a sub-section describing the fingerprints + a sub-section describing palmar dermatoglyphics.

A ‘Hand Model’ for recognizing Extraverts & Introverts!

with one comment

Hand model for recognizing Extraversion (extraverts) & Introversion (introverts).

The large majority of people (80%) can best be described displaying a mixture of ‘extravert’ and ‘introvert’ behaviors. However, about 10% of people tend to show consistent ‘extravert’ behavior (and a likewise percentage show ‘introvert’ behavior). Can the tendency towards extraversion and introversion be recognized from the hands of an individual?

A Dutch study (some results have already been reported in earlier posts) suggests the answer is: yes!

The picture above displays a ‘Hand Model for Extraversion’, which results from a multi-perspective hand study including 27 extraverts and 21 introverts (all Dutch citizens). The results e.g. point out:

“A discriminative analysis has pointed out that the ‘Hand Model for Extraversion’ can identify 85.4% of the subjects (41 out of 48) correctly as a HIGH of LOW scorer.”

More details:

6 Hand Signs for Extraverions / Introversion


Surprizing results?

Various earlier studies have reported results that now appear to make sense in the perspective of this new ‘Hand Model for Extraversion’:

– Sheldon’s ‘ectotonic’ somatotype is associated with introversion  (a summary is presented HERE)

– Low 2D:4D digit ratio has been associated with extraversion & sensation seeking (conflicting results have been reported over the years)

– Simian crease has been associated with introversion (more details HERE)

The Sydney Line & the Simian Crease are like ‘Fraternal Twins’!

leave a comment »

Normal palm creases - simian crease - Sydney line.

 Many people are fimiliar with the concept of a simian crease, but there is a likewise fascinating line that has a likewise significance: the Sydney line. In modern medical science both the simian crease & the Sydney line became known as a ‘minor physical anomaly’!

In a 1967 Belgian study Vrydagh-Laoureux pointed out that next to the well-known simian crease (or ‘simian line’ – which became well-known for it’s significance in Down syndrome), there is actually another hand line variant that is associated with related to Down’s syndrome. In the Belgian study this line was described as an ‘extended proximal palmar crease’.

NOTICE: In the traditional palmistry vocabulary this line is often described as: an ‘extended’ or very long head line.

Interestingly, only one year later Australian researchers (Purvis-Smith & Menser, 1968) found that this fascinating palmar line is also frequently found in the hands of patients with congenital rubella – and from that point this ‘fraternal twins line’ of the simian crease has been named: the Sydney line (or sometimes named: ‘Sydney crease’). This twin-analogy could become valuable because many people often find it difficult to discriminate a simian line from a Sydney line!

Example of the Sydney line presented by Purvis-Smith (1972).

Purvis-Smith defined the Sydney line as follows:

“A sydney line occurs where the proximal transverse crease extends beyond the midline axis of the fifth finger towards the ulnar border of the palm the ulnar border of the palm.” (Purvis-Smith, 1972) 


At the end of 20 century a new trend became appearant within the medical scientific community. Researchers began study so-called ‘minor physical anomalies‘ – which concern typically harmless inborn physical markers (that are typically associated with a specific prenatal period) – that have been associated in various disorders.

And especially in the 21 century this approach became popular among researchers who are studying the etiology of e.g. autism, ADHD, Down syndrome, hypoxia & schizophrenia.


Multi-Perspective Palm Reading demonstrates how the Sydney line & simian crease can be understood as a likewise hand line markers. Because (so far) a wide range of studies indicates that in far most diseases & syndromes where the simian crease has been recognized as a significant body marker… the Sydney line became recognized as a likewise significant body marker.

This pattern is seen e.g. in: diabetes mellitus, Down syndrome, fragile-X syndrome, rheumatoid arthritis, and schizophrenia!

Finally, discussion in the Modern Hand Reading Forum have shown that – despite the fact that a Sydney line and a simian line can never be observed in one hand – for many people it quite hard to discriminate a Sydney line from a simian crease. The picture below presents a few fundamental clues which could become helpful to understand the essential components of both lines.

NOTICE: A ‘common hand’ is featured with a life line [I], a head line [II], and a heart line [III]; and various hand line variations can be summarized with the following formulas [IIx = extended head line; II+III = simian crease]:


Obviously, there is a fundamental difference between the Sydney line and simian crease – therefore it appears more appropriate to describe them as ’fraternal twin lines’ instead of ‘identical twin lines’; because while they have a common nature… their manifestion shape is definitiely not identical.

More details are discussed in the following discussion:

Why do Physicians check the Hand Lines of Newborn Babies?

with 43 comments

Normal hand lines.

Why do physicians check the hand lines of newborn babies? Most newborns have two major creases on the palm, neither of which completely extend from one side of the palm to the other. However, a common variant, found in approximately 4% of western newborns, a transverse palmar crease is frequently inherited as a familial trait. Although single palmar creases are also associated with the hand in Down syndrome and other genetic disorders, the absence of other abnormalities on physical exam should reassure the examiner that no further evaluation is necessary.


Abnormal hand lines: a 'single palmar transverse crease', a.k.a. a simian line.

The pattern of palmar creases varies substantially within the general population. The formation of palmar creases, which occurs between the second and fifth months of prenatal development, depends e.g. on fetal movement. Once the palmar creases are formed, they remain unchanged throughout life.

More subtle normal variations of palmar creases can occur for a variety of reasons, including family background, age, and race. Many physicians are aware of the association between single transverse or bridged palmar creases, previously known as simian creases and Sydney creases, respectively, and the occurrence of Down syndrome. Although approximately 45% of patients who have Down syndrome have single transverse palmar creases, this finding occurs unilaterally (one hand) in 4% and bilaterally (both hands) in 1% of the general Caucasian population.


However, in the Chinese population, single transverse palmar creases may be considered a normal phenotypic variant; a recent study found that 16.8% of 3,345 healthy Chinese newborns had unilateral single transverse creases and 6.6% had bilateral single transverse creases.

Despite the high frequency of single transverse palmar creases in certain populations, aberrations in the flexion creases of the hands have the potential to signify abnormal fetal development. The association of abnormal flexion creases and various congenital disorders has been reported frequently in the literature. Studies have shown an increased incidence of single transverse palmar crease in children who have chromosome abnormalities and in low-birthweight infants. Therefore, it is reasonable to search for other congenital anomalies when evaluating an infant who has a single transverse palmar crease after taking into account the patient’s race and familial background.

When the crease occurs in isolation, however, no further evaluation is indicated.


Interestingly, these is also evidence that palmar creases (hand lines) and hand motorics are directly related!

In 2010 researchers from Korea reported results which suggest that union of hand lines (palm lines) appears to correlate with hand grip strength. And interestingly, a few months later a report from France presented results which suggest that hand strenght can be predicted from hand circumference alone. So, combining both reports indicates that a talent for hand strenght could very well be found in people who have a large hand circumference + fused hand lines, such as seen in simian line! An interesting hypothesis, which is suitable to be tested for it’s accuracy in the fields of modern palm reading.

Additionally, it might be interesting to notice here that the hand lines of apes (primates) are characterized by the presence of multiple ‘fused’ transverse crease. And Gorillas who are known as the strongest species among the primates have the widest (shortest) hand shape of all apes & primates.

How to classify the palmar lines: the simian line, Sydney line & the Suwon crease!

with 17 comments

The study of the palmar lines [folding creases] traces back to the ancient civilisations of the Chinese and Indians as early as 3,000 years B.C. Historically the palmar lines have been adopted as the most important ‘tool’ of the classic Indian palmist with the purpose for ‘the guidance of humanity’. This explains why in all regions of the world the palmar lines became synonymous with the stigma of fortune telling (advocated by so-called ‘predictive palmistry’) – and subsequently debarring the hand lines from the scientific courts.

However, since the end of the 19th century the hand lines have been adopted by scientific researchers for other purposes, including: anthropological classification, personal identification (though the fingerprints are more well-known for this purpose), and hand lines also have a diagnostic purpose!

The combination of the heart line (distal transverse crease) & head line (proximal transverse crease) could be described as representing the most important aspect of the palm lines. The typical characteristics of these two so-called ‘transverse creases‘ (= heart line + head line) can be described as follows (see also the picture above):

• COMMON LINES: The heart line & the head line typically manifest as 2 unconnected lines, and only in human hands these lines typically do not cross the full palm (in the primate palm there are usually mulitiple horizontal lines which cross the full palm).

• SYDNEY LINE: The Sydney line can be recognized by the presence of an extended head line which crosses the full palm, combined with the presence of a normal heart line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point, in medical science the Sydney line has been recognized in medical science as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. the hand in Down syndrome, the hand in fragile-X syndrome, the hand in psoriasis & the hand in Schizophrenia. The name‘Sydney line’ was introduced in 1968 by Australian researcher S.G. Purvis-Smith who reported a high prevalance of Sydney lines in patients with congenital rubella. 

• EXTENDED HEART LINE: The extended heart line can be recognized by the presence of a very long heart line which crosses the full palm, combined with the presence of a normal head line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point of view there is not much know about the extended heart line.

• SIMIAN CREASE: The simian crease can be recognized by the presence of a fusion between the head line and the heart line – resulting in the impression that one of both lines is missing. NOTICE: From a scientific point, in medical science the simian line has been recognized as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. many syndromes (including Down syndrome) and many diseases such as the hand diabetes mellitusthe hand in rheumatoid arthritis. The name simian line was introduced in 1877 by French physician Paul Broca who described it as an unusual characteristic for the human hand.

The Suwon crease can be recognized by the presence of two complete head lines (not a splitting head line, nor an interrupted head line), and the upper head line fuses/connects with the heart line. NOTICE: The history of the Suwon crease is still very young: it was first described in 2010 by Korean researchers, who found it only in 0.7% of a large Korean sample of 3.532 male hands (in the 1664 female hands it was never observed).

An advanced definition of various types of palmar creases.


The Korean researchers have presented in 2010 a new detailed method for classifying the various types of palmar lines, which includes some interesting elements which can be applied in Multi-Perspective Palm Reading:

“Definition of major and minor palm creases. Major palm creases are defined as follows. Radial longitudinal crease (I) becomes distinct according to the flexion of carpometacarpal joints of the thumb. Proximal (II) and distal transverse creases (III) become distinct according to the flexion of the metacarpophalangeal joints of the second to fifth fingers. Minor palm creases are defined as palm creases which are narrower than the two times of the epidermal groove width in palmprints (1), apart from major palm creases (2), crossing major palm creases (3), or leading to major palm creases by the sharpened end (4).”
