- Abstract
- Objective: This study investigates whether a general articulatory technique performed on the hip does increase blood flow and rate through the femoral artery at a statistically significant level when compared to a non-treatment (control) group. Primary Hypothesis: Femoral blood flow will increase in the experimental group compared to the control group at a statistically significant level. Secondary Hypothesis: Blood pressure will decrease in the experimental group when compared to the control at a significant level. Null Hypothesis: There will be no significant difference in the observed change in either blood flow or blood pressure when comparing experimental and control groups. Design: The study was based on primary data gathering using 45 subjects divided into two groups, in a randomized control trial. The groups were divided: Experimental Group: 11 Male - 12 Female - Mean age 24.4 - Mode age 22 -Mean activity level 2.3 Control Group: 11 Male - 11 Female - Mean age 24.8 - Mode age 23 – Mean activity level 2.6 Each participant was a non-smoking ESO student with no prior cardiovascular medical history or hip trauma/surgery, Intervention: 23 subjects received general articulation of the hip joint for a 2 minute period, while the 22 subjects in the control group were asked to lay down for the same time period Outcome Measure: Femoral artery blood velocity and diameter were assessed in the right hip immediately before and after the treatment-or non-treatment in the case of control - period, similarly blood pressure was taken from the left arm of all patients for the same intervals. Results: ANOVA testing showed statistically significant increase in blood velocity, arterial lumen diameter and blood flow (P<0.01), significant results were further yielded when calculating the error bounds of the data, control and experimental bounds did not overlap in any instance. There was no significant increase or decrease in blood pressure when comparing the two groups (P>0.05). Similar significance levels were achieved with an asymptomatic significance (2-'tailed) test coupled with the Mann-Whitney U Test. Conclusion: General articulatory technique of the hip did produce a statistically significant increase in femoral artery blood flow, diameter and flow velocity, while systemic blood pressure remained statistically unchanged - implying that cardiovascular changes are localized. The degree to which conclusions may be extrapolated are limited due to the demographic of the sample not being representative of the wider public. Testing on a larger scale accounting for appropriate demography should be conducted.
