Abstract
Ageing is associated with age related musculoskeletal changes with subsequent function affection, in addition to cognitive deterioration that could be due to age related changes in CNS, all of these affect quality of life.
Optimization of function independency and quality of life is the target of successful aging.
The current study was directed to compare the performance of different assessment tools of physical performance in community dwelling elderly female and to validate hand grip strength measurement using sphygmomanometer compared by jamar dynamometer.
This cross sectional –cohort study was conducted where 100 elderly females aged 60 years old or more and aberrantly health who come to Ain Shams University out-patient clinic and care givers of the admitted inpatients and accepted to participate in the study were recruited for the study. All the participants were subjected to comprehensive geriatric assessment including; cognitive function assessment by using Mini-mental status examination, screening for depression using GDS-15.
Assessment of function decline by using both subjective methods including (ADL), (IADL), modified barthel which were followed after 3 months and (IPEQ-w)which assess physical activity in the past week and objective methods including HGS by Jamar dynamometry and sphygmomanometer, SPPB.
The current study showed that the prevalence of ADL and IADL dependency at the base line ssessment were 43% and 37% respectively and after 3 months follow up, these results did not show statistically significance.
Cognition, depression, physical activity, muscle state showed statistically significance between ADL and IADL dependent and independent groups, while age, hypertension were statistically significance between IADL dependent and independent groups.
Kappa agreement between ADL, IADL, Modified Barthel was performed, it was strongest between ADL and modified barthel which was 85%.
Receiver operating characteristic curve (ROC) for predicting ADL dependency at base line assessment of the study which showed the optimal cut off off point for hand grip strength by Jamar dynamometer was calculated ≤9 Kg/strength, and it was ≤60 mmHg by sphygmomanometer. The optimal cut off point of total SPPB to predict ADL dependency was ≤2.
The correlation between hand grip strength measured by Jamar and sphygmomanometer with ADL and IADL were studied and showed a positive correlation between hand grip strength measured by Jamar dynamometer and sphygmomanometer with ADL and IADL.
linear regression analysis for factors associated with Hand grip strength as measured by Jamar dynamometer was used to establish the conversion equation to predict Hand Grip strength in Kg/strength using Hand grip strength measured in mmHg using sphygmomanometer and age.
Grip strength as measured by Jamar (Kg/strength) =
10.390 + [(0.078 * grip strength as measured by sphygmomanometer in mmHg) + (-0.134 * age yrs)]
Comparison between calculated Hand grip strength using the previous equation and Hand grip strength by jamar which shows no statistically significance difference which means the previous equation can be used to estimate grip strength by jamar using age and grip strength by sphygmomanometer.
