Association of Hand Grip Strength and with Writing Speed (Endurance) Among the Students
The objective of current study was to determine the association of hand grip strength and endurance with handwriting speed among the students.
Grip strength of hand indicates overall muscle strength that was measured by using a hand dynamometer, which was considered to be the gold standard for measurement of grip strength and endurance.
Observational study was conducted at Lahore College of Physical Therapy LMDC Lahore with a sample of 87 undergraduate male and female students after prior consent. The maximal grip strength and muscle endurances were measured through dynamometer whereas the writing speed was measured through Letters Per Minute (LPM) test. A Collective data comprising strength, endurance and the total letters written by each subject was analyzed by using SPSS.
This study shows that a significant difference was present in handgrip strength of females than males but writing speed and endurance of females was much greater than males. 77% of females, who fell into the minimal strength category that was (strength<23) had a better endurance and were able to write greater number of letters as compared to those who fell into the maximal strength category that was (strength>23) evident from the significant value (P < 0.000). Whereas 23% of males who fell into the maximal strength category that was (strength>37.5) also had a maximal endurance and were able to write greater number of letters as compared to the males who fell into the minimal strength category that was (strength<37.5), they had minimal endurance and were able to write less number of letters, evident from the significant value (P < 0.05).
The findings of this study concluded that there was a positive association between strength and writing speed (endurance).
