FINGERTIP BIOMETRY – Fingertips Signal Clues for Schizophrenia!

leave a comment »

Many studies have revealed that syndromes & diseases become manifest in hand functions & many aspects in the morphology of the hands. Interestingly, a closer look a the studies performed so far indicates that for the hand in schizophrenia the significance of the fingertips is more important than in other disorders!

A person diagnosed with schizophrenia may experience hallucinations (most reported are hearing voices), delusions (often bizarre or persecutory in nature), and disorganized thinking and speech. But there are no symptoms which are seen in all schizophrenic patients.

 In order to understand the connection between hands and schizophrenia thorougly, it is important to be aware of the essential difference between the so-calledpositive symptoms‘ and ‘negative symptoms. Because some of the fingertip characteristics in schizophrenia are associated with only category of the symptoms! (More details will be revealed later)

NOTICE:  The ‘positive symptoms’ in schizoprenia are those symptoms that most individuals do not normally experience but are present in people with schizophrenia (such as: hallucinations & disordered speech). And the ‘negative symptoms‘ are deficits of normal emotional responses or of other thought processes, and respond less well to medication (such as: blunted affect & poverty of speech).


FIVE FINGERTIP DIMENSIONS IN SCHIZOPHRENIA!

A closer study of the reports published so far, unveals that in schizophrenia at least 5 dimensions of the fingertips  provide significant clues, including:

FINGERTIP DIMENSION 1 – Fingerprints:

– 1a: extralimital triradii (prevalence: 6.6% in schizophrenics vs. 1.5% in controls);
– 1b: fingerprint type asymmetry on 3 or more fingers.

FINGERTIP DIMENSION 2 – Fingernails:

– small & underdeveloped (prevalence: 18.8% in schizophrenics vs. 2.0% in controls).

FINGERTIP DIMENSION 3 – Shape:

– 3a: short length is typical (prevalence: unknown);
– 3b: spatulate is typical (prevalence: 42.4% in schizophrenics vs 21.7% in controls).

FINGERTIP DIMENSION 4 – Skin:

– blood vessels in proximal nail fold are visible (prevalence: 20-70% in schizophrenics vs. 3-7% in controls);

FINGERTIP DIMENSION 5 – Creases:

– excessive (prevalence: unknown);

(The sources for the percentages are listed in the article: How to make a Palm Reading Assessment
for SCHIZOPHRENIA?
)


 FINGERTIPS & THE BRAIN:

Interestingly, there appears to be a connection as well regarding how schizophrenia is linked with the brain! Because after Penfield described in his cortical homunculus (see the picture on the right) in the 1940’s how the primary somatosensory cortex is linked with e.g. the fingertips, brain studies have later revealed that schizophrenia is often featured with abnormalities in the same region of the brain (+ other near located parts of the brain, including: the thalamus & frontal lobe). 


FINGERTIP DIMENSIONS IN OTHER DISORDERS?:

The following summary shows that only three out of the five fingertip dimensions that provide significant clues for schizophrenia, also display significant clues in 6 other diseases & syndromes that are well known for displaying significant hand markers. Only rheumatoid arthritis provides clues in these three fingertip dimensions!
 

FINGERTIP DIMENSION 1 – Fingerprints:

Significant for the hand in Down syndrome, the hand in diabetes mellitus, the hand in fragile-X syndrome, and the hand in rheumatoid arthritis.

FINGERTIP DIMENSION 2 – Fingernails:

Significiant for the hand in Down syndrome, the hand in diabetes mellitus, the hand in Marfan syndrome, the hand in psoriasis, and the hand in rheumatoid arthritis.

FINGERTIP DIMENSION 3 – Shape:

Significant for the hand in Marfan syndrome, the hand in psoriasis, and the hand in rheumatoid arthritis.

FINGERTIP DIMENSION 4 – Skin:

No significant markers for any of the six studied diseases & syndromes.

FINGERTIP DIMENSION 5 – Creases:

No significant markers for any of the six studied diseases & syndromes.

These materials indicate that a significant part of the correlations between the hands & schizophrenia is found at the fingertips. To be continued!

Penrose's brain homunculus describes how the fingertips relate to the primary somatosensory cortex & the primary somatomotoric cortex.

HAND ANTHROPOMETRY – From Leonardo Da Vinci to NASA & US army!

leave a comment »

Historically, Leonardo da Vinici’s ‘Vitruvian Man’ can be described as one of the earliest examples of anthropometry. The drawing was created by Leonardo da Vinci around the year 1487, and is accompanied by notes based on the work of the famed architect, Vitruvius.

The drawing, which is in pen and ink on paper, depicts a male figure in two superimposed positions with his arms and legs apart and simultaneously inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man.

Interestingly, Leonardo’s comments for the proportions of th e ‘Vitruvian Man‘ includes a few passage where the hands and fingers are mentioned, quote:

“For the human body is so designed by nature that the face, from the chin to the top of the forehead and the lowest roots of the hair, is a tenth part of the whole height; the open hand from the wrist to the tip of the middle finger is just the same; the head from the chin to the crown is an eighth, and with the neck and shoulder from the top of the breast to the lowest roots of the hair is a sixth; from the middle of the breast to the summit of the crown is a fourth. If we take the height of the face itself, the distance from the bottom of the chin to the under side of the nostrils is one third of it; the nose from the under side of the nostrils to a line between the eyebrows is the same; from there to the lowest roots of the hair is also a third, comprising the forehead. The length of the foot is one sixth of the height of the body; of the forearm, one fourth; and the breadth of the breast is also one fourth. The other members, too, have their own symmetrical proportions, and it was by employing them that the famous painters and sculptors of antiquity attained to great and endless renown. Similarly, in the members of a temple there ought to be the greatest harmony in the symmetrical relations of the different parts to the general magnitude of the whole. Then again, in the human body the central point is naturally the navel. For if a man be placed flat on his back, with his hands and feet extended, and a pair of compasses centred at his navel, the fingers and toes of his two hands and feet will touch the circumference of a circle described therefrom. And just as the human body yields a circular outline, so too a square figure may be found from it. For if we measure the distance from the soles of the feet to the top of the head, and then apply that measure to the outstretched arms, the breadth will be found to be the same as the height, as in the case of plane surfaces which are perfectly square.”

Leonardo da Vinci’s comment about the proportion of the average hand was quite right, but the field of anthropometry has later developed more precise methods in order to describe the most important individual variations concerning the human body. Various sources of anthropometric hand data indicate the average hand length is close to 11% of body height (usually slightly smaller).


ANTHROPOMETRY TODAY:

Today, anthropometry plays an important role in industrial design, clothing design, ergonomics and architecture where statistical data about the distribution of body dimensions in the population are used to optimize products.


DATA FROM THE NASA & US ARMY:
 

In the last decade of the 20 century reports became available developed by the NASA & the US army – which include data for at least 20 characteristics of the human hand shape, including e.g. hand length, hand breadth & finger length. The data in the picture above represents static human physical characteristics of the adult hand, presented in 2000 by the Department of Defense Human Factors Engineering Technical Advisory Group.

The picture below presents at the bottom some average data based on German, UK & American populations – which provide useful ‘points of reference’ in the perspective of biometry & Multi-Perspective Palm Reading.


Finally, regarding Leonardo da Vinci it might be interesting to notice here that in 2008 a report was published describing characteristics of his fingerprint:
