Hand Diagnostics & Psychiatry:
hand morphology, hand expression, thumb expression & Charlotte Wolff
LEVEL 2: Hand morphology and schizophrenia.
So far the relationship between hand morphology and schizophrenia has been studied in about four well-known studies:
In the year 1928 Friedemann1 studied the hand morphology in a small sample of schizophrenic patients.
A few decades later Charlotte Wolff presented the book 'The hand in psychological diagnosis'2 - which includes one of the very few studies focussed on a large number of hand aspects. Wolff describes e.g. the relationship with a certain hand type called 'the elementair regressive hand' - which is reported to be frequently observed on people with a mental disability.
The handtypes which are usually most frequently observed on 'normal' people - the so-called: 'fleshy motoric hand' and 'the bony motoric hand' - were hardly observed on the schizophrenics studied by Wolff.
These observations made by Wolff 2 were confirmed in a 'double-blind' Israelian study executed in 1982 by Haft Pomrock & Ginath3.
The study reported e.g. that the hands of schizophrenics are characterized by a 'lack of hand expression' in the thumb and the complete hand. The 'lack of hand expression' related figures presented by Haft Pomrock & Ginath are presented in tabel C-2 en tabel C-3.

|- Rating:-------------------- 0-- 1-- 2-- 3-- 4-- N|
- Control group -------- 0-- 0-- 1- 41- 8- 50
Meaning of the 'Rating':
- 0 = lack of expression, no vitality;
- 1 = rigid epression;
- 2 = weak expression;
- 3 = vital expression;
- 4 = strong expression;
- P < 0.0001
