| Summary: | Objective: The objective of this study was to analyze the correlation between
repetition (frequency of movement), force (length of hammer, the fitting of
hammer to the hand, weight of hammer) and work periode and Carpal Tunnel
Syndrome (CTS) among manually stone breaker at Rowosari Village,
Tembalang district, Semarang City.
Method: A cross sectional design was used in this study to 79 person.
Independent variables were frequency of movement, length of hammer, the
fitting of hammer to hand, weight of hammer and working periode). Dependent
variable was CTS. All of samples were women with incidental sampling
method. Data collection was done through interviews about characteristic of
samples, CTS complains and work periode, inspections about working
condition, sensibility test (two point discrimination and monofilament) and
provocation test (Phalen�s and Tinel�s) and meassurment of frequency, length of
hammer, diameter of hammer, anthropometry of hand, weight of hammer.
Result: The study found that there were no significant correlation between
frequency of movement (p = 0,062), length of handle (p = 0,181), the fitting of
hammer to hand (p = 0,292), weight of hammer (p = 0,483) and working
periode (p = 0,488)) and CTS. Contribution of all independent variables to
cause CTS was 1,7 %, and 98,3 % by the other factors.
Conclution: no significant correlation were found between frequency, length of
handle, the fitting of handle to hand, weight of hammer, work periode and CTS.
Relative contribution of all variables to cause CTS were 1,7% and 98,3% cause
by the other factors.
