Abstract
defined as a condition in which individuals have
a systolic pressure of equal to or greater than
140mmHg and a diastolic pressure of equal to or
greater than 90 mmHg on at least three occasions,
or individuals who require medication to remain
normotensive [3-5] .
!
The aim of this study was to investigate the effect of foot
reflexology on blood pressure and quality of life among
hypertensive patients. A quasi-experimental study was conducted for patients with hypertension attended the outpatient
clinic of the Specialized Medical Hospital at Mansoura University, Egypt, enrolled in this study during six months,
between 15 May and 14 October 2010 were randomly allocated
into two equal groups (40 in the foot reflexology group
(intervention), and 40 in the control group.
Hypertension is one of the conditions purported
to be improved by complementary therapies such
as foot reflexology [1,2] . Pressure techniques applied
on the feet are believed to help unblock nerve
supply and improve blood flow, which may help
the body to function at its peak 1. It is claimed
that reflexology relieves stress and tension by
inducing relaxation [1,6] . By doing this, it brings
about vasodilatation, blood pressure, improved
blood flow and provision of oxygen-rich nutrients
to cells [1,7,8] . Some authors suggest that 70 to
80% of all diseases and illnesses come from stress
including hypertension, migraine, headaches, the
common cold, ulcers and coronary heart disease
[1,9] .
Two tools were used for data collection:
I : Demographic and medical interview schedule.
II: Quality of Life Questionnaire.
Systolic blood pressure decreased significantly in intervention group from 160.2mmHg to 136.5mmHg compared to
(162.5mmHg to 155.2mmHg) in controls. There was a statistically significant decrease in means of diastolic blood pressure
between pre and post intervention (102.0mmHg –87.5mmHg)
within the intervention group ( p<0.05), Change in control
group was not proved to be statistically significant
(100.1mmHg –96.4mmHg pre and post readings respectively,
p>0.05). There was no evidence for improvement in Quality
of Life in either group (pre levels was 42.2, 47.1 and post
levels was 45.9, 47.4 in the 2 groups respectively). This study
supported that foot reflexology can reduce blood pressure
levels in patients with hypertension, it did not support that
foot reflexology could improve quality of life in these patients.
Future research is needed to support these findings specially
the negative ones. It is recommended that qualitative research
might be used in combination with quantitative research to
determine details of patients' feelings, interactions, attitudes,
cultural influences and satisfaction after intervention.
Although not yet widely used, relaxation techniques are potentially valuable nonpharmacological
treatments to lower blood pressure. Such techniques
include progressive muscle relaxation, etc ... [10] .
Complementary therapies such as massage and
reflexology are claimed to help reduce symptoms
of stress and tension resulting in a decrease in
blood pressure, and an adjustment of body, mind
and spirit to a state of harmony [11] ; they can also
help improve quality of life [12] .
Key Words: Nursing Intervention – Foot reflexology – Hypertension – Blood pressure – Quality of life.

the disease and any treatment side effects but may
also, be worried and frustrated about their disease,
may be open to complementary therapies as an
adjunct to conventional treatments.
Reflexology, as a comprehensive approach and
a nursing intervention that supports traditional
care; can be used in the medical treatments [15,16] .
Many studies have investigated reflexology as a
noninvasive and non-pharmacological nursing
intervention in its various aspects such as: The
impact of reflexology on hypotension without any
known reasons, reducing triglyceride and blood
sugar, improving nausea and vomiting in cancer
patients undergoing chemotherapy, reducing depression and improving immune system function,
improving pain and anxiety of the cancer patients
and decrease the fatigue in pregnant women [17] .
However, in a pilot (small) study conducted on the
anxiety of patients before and after the coronary
artery bypass graft surgery, this method has a
significant effect on the physiological parameters
of the patients [11] .
The aim of this study was to: Investigate the
effect of foot reflexology on decreasing blood
pressure and the improvement in mean quality of
life among hypertensive patients.
It has been found that health care professionals
have increased their use of complementary therapies
to help relieve uncomfortable symptoms and suffering of patients with chronic diseases [18] . Foot
reflexology is a well known complementary therapy
which claims to help the body achieve homeostasis.
It is believed that pressing specific areas on the
feet related to specific glands or organs of the body
can help these glands and organs to function at
their peak, allowing the body to heal itself [1,2] .
The principal difference between massage and
touch and foot reflexology is that foot reflexology
provides not only the relaxation effect obtained
from massage or touch but is said to also improve
body immunity contributing to healing process
[1,2] . Foot reflexology has been scientifically researched in many studies to explore the claimed
benefits [19,20] . Some studies have supported its
ability to reduce anxiety and pain [21-23] . However,
there has been little scientific evidence to support
the claim that foot reflexology can reduce blood
pressure and serum lipids, and can improve the
quality of life in patients with hypertension [2124] . The purpose of this study was to begin to fill
this gap by investigating the influence of foot
reflexology on blood pressure, serum lipids and
quality of life in hypertensive patients.
The role of nursing staff is to care for patients
as a whole, encompassing body, mind and spirit
[24] . Demonstrating concern for patients’ needs
helps to achieve holistic care [25] . Patients with a
chronic disease, who are suffering not only from
Hypotheses:
1- There will be a decrease in mean blood pressure
level in foot reflexology group (intervention)
relative to the control group (no intervention)
by the end of four weeks of implementation.
2- There will be an improvement in mean quality
of life scores in foot reflexology group (intervention) relative to the control group (routine
management) by the end of four weeks of implementation.
Subjects and Methods
!
Research design: A quasi-experimental, prospective study was conducted for patients with
hypertension enrolled in this study. Two groups
were studied; foot reflexology group (intervention)
and control group (routine management). All patients continued their usual medical treatment
throughout the duration of the study.
Subjects and setting: The subjects of this study
consisted of 80 consecutive eligible patients with
hypertension who attended the outpatient clinic of
the Specialized Medical Hospital at Mansoura
University, Egypt; Subjects were matched and
similar in gender, age, educational background,
economic factors, marital status, duration of hypertension, medical history and treatments, lifestyle
characteristics, and co-morbidities. Patients were
randomly allocated and divided to equal numbers.
into 40 patients in intervention and control group.
Data collection was undertaken during six months,
between May and October 2010. Subjects were
eligible for inclusion in the study if they were:
Adult males and females, aged 18 years and above,
had hypertension (systolic blood pressure greater
than or equal to 140mmHg, and diastolic blood
pressure greater than or equal to 90mmHg) with
or without hyperlipidaemia, had two feet, gave
informed consent to be involved in the study and
fully conscious. Subjects were excluded from the
study if they had thrombotic disease of the lower
extremities, foot ulcers, foot infections/diseases,
or had undergone foot surgery, and pregnant women
were excluded. Other criteria of exclusion were:
recent major surgery such as open heart surgery,
Karima Elshamy & Eman Elsafety
lesions or fractures in foot, sprains or bruises of
the lower extremities, hemorrhage, epilepsy, diabetic foot complication, thrombosis, kidney stone
or gallbladder, irregular heart rate and hypotension
[26,27] . Patients with open skin wounds on their
feet, a foot tumor or foot metastasis, or radiation
treatment to the feet was also excluded [28] .
Tools of the study:
Two tools were used in the study:
Tool I: Demographic and medical interview schedule:
A demographic data questionnaire was written
in Arabic language, This tool was developed by
Soliman H. (2007) in a pervious study which included questions on gender, age, marital status,
educational background, economic factors (specifically, whether patients had financial problems),
duration of hypertension, medical history and
treatments, co-morbidities, and top medical treatments. It also included questions about lifestyle
modification such as fat/salty foods intake, exercise,
smoking, alcohol intake, recreation and relaxation.
This questionnaire was completed by participants
at the first day of the study [29] .
Tool II: Quality of life questionnaire:
The World Health Organization Quality of LifeBREF, Arabic version (WHOQOL-BREF) questionnaire was used. The WHOQOL-BREF is a 26item, self-administered, generic questionnaire that
is a short version of the WHOQOL-100 scale. The
response options range from 1 (very dissatisfied/
very poor) to 5 (very satisfied/very good). It consists
of domains and facets (or sub-domains). The items
on “overall rating of QOL” (OQOL) and subjective
satisfaction with health constitute the general facet
on OQOL and health. The more popular model for
interpreting the scores has four domains, namely,
physical health (seven items), psychological health
(six items), social relations (three items) and environment (eight items). Participants completed this
questionnaire at the start of the study and following
four weeks of intervention [30] .
Methods:
Official permission to conduct the study was
taken from the hospital responsible authorities
after explaining study’s aims.
Content validity: The content validity of the
first tool along with the including and excluding
criteria was submitted to 10 experts in the field of
medical surgical nursing, medicine and physiotherapy for their opinion on the items in the tool and
the criteria. There was complete agreement by
195
experts and minimal modifications were made
based on the given suggestion.
Reliability of the tool: A new standardized
sphygmomanometer and stethoscope were used to
check the blood pressure. The reliability of the
sphygmomanometer and stethoscope were checked
with other standardized sphygmomanometer and
stethoscope. The readings were matched with the
comparative devices used for the reliability testing.
Pilot study: A pilot study was conducted in the
previously mentioned setting, from 5 May 2010
to 10 May 2010. The investigator obtained formal
permission from the concerned authority prior to
the study. The study was conducted on 10 hypertensive patients who fulfilled the inclusion criteria
for the selection of the sample. The purpose of the
study was explained to the subjects and consents
were obtained after assuring privacy and confidentiality. Baseline information was collected; and
blood pressure was checked after intervention. The
tools were found feasible and practical. No further
changes were made in the tool after the pilot study
and the investigator proceeded for the main study.
Before taking part in the study, all potential
participants were provided with information about
the study topic; the study objectives, study methodology, potential risks, and treatment benefits,
privacy and confidentiality were assured. Patients
who accepted to participate were assured that their
participation was entirely voluntary and informed
of their rights as research subjects. The investigator
clarified this information verbally and provided
further details upon request. Patients who wished
to participate in the study were asked to give
consent to confirm their willingness to be involved
in the study. They were also informed that they
could withdraw from the study at any time without
any impact on their treatment.
Prior to randomization, participants were asked
to complete a demographic data questionnaire and
the World Health Organization Quality of LifeBREF (WHO QOL BREF) questionnaire. Revision
of their laboratory data for: A blood sugar, kidney
function, lipids and gout. Electrocardiogram was
also done for all participants in the study to exclude
patients with irregular heart rate.
Eligible participants were randomly allocated
into two equal groups 40 participants in the foot
reflexology group (intervention) and 40 in the
control group (routine management). Immediately
prior to each treatment session, patients were
provided with 10-minute rest. Following this rest
time, their blood pressure level was measured by

Effect of Nursing Interventions Using Foot Reflexology on Blood Pressure
trained nurses in the outpatient clinic using a
standard mercury sphygmomanometer and stethoscope before and after each treatment.
The researchers worked to decrease factors
affecting blood pressure such as emotion, exercise,
respiration, meals, tobacco, alcohol, temperature,
pain, bladder distension based on the protocols for
taking blood pressure [31] . The sphygmomanometer
was calibrated before use.
The process of reflexotherapy was explained
to the intervention group. Participants in the foot
reflexology group received their usual medical
treatment and a 30-minute foot reflexology treatment (15m for each foot) twice a week for four
weeks. Participants in the control group received
their routine usual medical treatment which included physical examination of feet.
The research assistant conducted the reflexotherapy; first of all, the relaxation technique was
used from the footstalk toward the sole (plantar
surfaces) at the beginning of the session. Then,
four major plantar reflexology points (solar plexus,
pituitary, heart and liver) were put under pressure
using the thumbs. The other reflexology areas of
the plantar surface of the foot were also massaged
and finally intervention was put to an end with
massaging the solar plexus by the researcher.
At the end of the study (4 weeks), immediately
after the intervention, blood pressure level was
measured again by the by the research assistant in
the clinic. Participants were asked to complete the
WHO QOL-BREF again. After data collection,
patients in the control group received the same
foot reflexology to avoid depriving them from a
potentially valuable technique.

Descriptive statistics included numbers and
percentages for qualitative variables and means
and standard deviations for quantitative variables.
Comparison of means was achieved using 2-tail ttest for independent samples. Chi-square test was
used to compare percentages. The threshold of
significance was fixed at the 5% level [33,34] .
Results
!
Demographic characteristics of participants:
For this study, the 80 participants were randomly
allocated into two groups: (40 in the foot reflexology group (intervention), and 40 in the control
group (routine management).
Demographic data for the participants was
collected and then analyzed for gender, age, marital
status, educational background, economic factors,
duration of hypertension, medical history, period
of treatment for hypertension, and co-morbidities.
Lifestyle data such as fat/salty foods intake, smoking, alcohol intake, exercise and recreation / relaxation was also determined. The data is presented
in Tables (1-6).
Demographic data of control and intervention
groups were similar without statistically significant
differences in gender, age, educational background,
economic factors, lifestyle characteristics, comorbidities and medical treatments, marital status,
the length of time experiencing hypertension and
the length of time having treatment for hypertension.
Demographic characteristics of the studied
groups (n=80): Most of patients were married in
foot reflexology and control group (77.5%) and
(75.0%). Both groups reported achieving similar
levels of university education 53.7% and 52.5%
of in the foot reflexology group and control group
respectively. The majority of participants in both
groups had financial problems – 90.0% in the foot
reflexology group, 87.5% in the control group.
There was no difference between the groups in the
length of time that participants had been diagnosed
with hypertension, and the duration having treatment for hypertension (Table 1).
Lifestyle characteristics of the studied groups
(n=80): Almost more than 70% of participants in
the two groups ate fat/salty foods more than 16/wk – 82.5 % in the foot reflexology group, 85.0%
in the control group. Most participants did not
smoke – 55.0% and 55.0% in the foot reflexology
and control groups respectively. The majority of
participants did not drink alcohol at all – 98.0%
in the foot reflexology group and 99.0% in the
197
control group. These results may be related to
Egyptian culture and religion. Most of participants
(67.5%) in the foot reflexology group and 70.0%
of participants in the control group had a sedentary
lifestyle, exercising less than once a week. More
than 80% of participants in each group had recreation or relaxation time more than once a week
90.0% in the foot reflexology group, 87.5% in the
control group (Table 2).
Top six co-morbidities of the two study groups:
There was no difference in both groups related to
the top six co-morbidities and also other comorbidities. Some participants had more than one
of co-morbidity, thus the total does not equal 100%.
The most co morbid was diabetes 75.0% and 72.5

Top ten medical treatments of the two study
groups: There was no difference in both groups
related to the top ten medical treatments and also
other treatments. Some participants had more than
one medical treatment, thus the total did not equal
100% (Table 4).
Results of blood pressure and the quality of
life: There was a statistically significant decrease
in means of systolic blood pressure between pre
and post intervention (160.2mmHg versus 136.5
mmHg) within the intervention group respectively
(p<0.05). Change in control group was not proved
to be statistically significant (162.5mmHg-155.2
mmHg pre and post readings respectively) ( p>0.05).
There was a statistically significant decrease
in means of diastolic blood pressure between pre
and post intervention (102.0mmHg versus 87.5
mmHg) within the intervention group (p<0.05),
Change in control group was not proved to be
statistically significant (100.1mmHg versus 96.4
mmHg pre and post readings respectively, p>0.05).
There was a little difference in means of quality
of life scores between groups before treatment.
Differences was not proved to be statistically
significant (p>0.05).
Mean of quality of life and health satisfaction
scores were slightly higher for participants in the
foot reflexology group than for participants in the
control group. Mean of physical health, psychological health, social relationships and environment
scores for participants in the control group were
slightly higher than for participants in the foot
reflexology group. Quality of life scores pre-post
intervention was neither statistically nor clinically
significant. Differences were not proved to be
statistically significant (p>0.05).
There was a significant increase in all patients
comments before and after intervention in the foot
reflexology group, (75.0%) of patients in the foot
reflexology group feel satisfied after the intervention, compared to (52.5%) before intervention.
Patients comments indicated that they felt comfortable, relaxed, and believed that treatment could
relieve fatigue, numbness and cramps in their feet.
p<0.05. Regarding the control group, all patients
'comments before and after routine care indicated
no significant differences p>0.05 (Table 6).
Post intervention results:
There was a decrease in systolic blood pressure
of 23.7mmHg in the reflexology group compared
with a decrease of 7.3mmHg in the control group.
There was a decrease in diastolic blood pressure
of 14.5mmHg in the reflexology group compared
with a decrease of 3.7mmHg in the control group
(Table 5).
The findings showed that foot reflexology lower
blood pressure in patients with hypertension, but
it had little impact on the quality of life in these
patients (Table 5).

Effect of Nursing Interventions Using Foot Reflexology on Blood Pressure
Discussion
!
Hypothesis one: There is a decrease in mean
blood pressure level between the foot reflexology
and control groups at the end of four weeks of
treatment. Analyses of data in this study indicated
that there was a statistically significant difference
in mean blood pressure between the foot reflexology group and control group at the end of four
weeks of treatment. The mean diastolic blood
pressure in the foot reflexology group was statistically significantly lower than in the control group
(p<0.05).
Frankel [35] explored the effects of foot reflexology on the baroreceptor reflex, which controls
blood pressure. He found that baroreceptor reflex
sensitivity was significantly lowered in the intervention groups (foot reflexology and foot massage),
compared with the control group. Baroreceptor
reflex sensitivity was measured using sinus arrhythmia and phase IV of the Valsalva maneuver, a
period in the Valsalva maneuver during which
blood pressure is substantially raised above the
baseline. These blood pressure results are different
to those outlined by Frankel [35] who found that,
between foot reflexology and foot massage, there
was no significant difference in resting blood
pressure after intervention.
The results of our study supported the hypothesis that foot reflexology decreases blood pressure
in patients with hypertension. In this study, the
results in relation to blood pressure are comparable
to those of Park and Cho [24] who found in their
research that there were no significant differences
in diastolic blood pressure and LDL cholesterol
between the foot reflexology group and the control
group (who received no intervention). In contrast
with this study, however, Park and Cho found that
systolic blood pressure and triglyceride levels
significantly decreased in their foot reflexology
group compared to their control group. In addition,
life satisfaction was significantly improved in the
foot reflexology group.
Compared to Park and Cho’s [24] study (2004),
our study was performed using a bigger sample
size and with control as a comparison intervention
(Park and Cho [24] , provided foot reflexology only
in a small group of 34 hypertensive patients-18 in
the foot reflexology group and 16 in the control
group who received no intervention). From both
studies, we can conclude that foot reflexology has
been proved to lower diastolic and systolic blood
pressure. However, its effects on quality of life or
life satisfaction in patients with hypertension are
ambiguous.
Our study showed that foot reflexology was
more likely to reduce diastolic and systolic blood
pressure than control group. Previous studies supporting these results were a study by Hayes & Cox
[36] and another by Jirayingmongkol et al. [37] .
However, these two studies used different measurement and foot massage procedures to test blood
pressure. Hayes and Cox [36] used mean arterial
blood pressure as an indicator of measurement of
physiological and psychological stress in patients
in a critical care unit. They found that there was
a significant decrease in heart rate, mean arterial
blood pressure and respirations during the foot
massage intervention in participants in the foot
massage group compared to those in the control
group who received no intervention. Jirayingmongkol et al. [37] used Thai foot massage which is
quite different in style and procedure from the
current study to measure vital signs in older subjects. They found that Thai foot massages significantly decreased blood pressure, pulse rate and
respiratory rate in these people. Given the differences in measuring, procedures and samples, we
can not conclude that foot massage can lower blood
pressure in patients with hypertension.
Hypothesis two: There is an improvement in
mean quality of life between the foot reflexology
and control groups at the end of four weeks of
treatment p >0.05. Results from this study showed
no significant difference in mean quality of life
for both groups. These results differed markedly
from study results of Park & Cho [24] and Hodgson
[12] . Park & Cho [24] showed that foot reflexology
significantly improved life satisfaction in 34 patients with hypertension. This study did not support
Park and Cho’s [24] conclusions.
Similarly, Hodgson [12] found that foot reflexology could improve quality of life. However,
Hodgson’s study was based on cancer patients and
is difficult therefore to compare with the effects
of foot reflexology on quality of life in patients
with hypertension. In addition, the sample size in
her study was small-only twelve subjects including
six in the foot reflexology group, and six in the
gentle foot massage group. Hodgson used the visual
analogue scales for cancer patients to measure
quality of life, as contrasted from the current study’s
use of the WHOQOLBREF World Health Organization [30] which is suitable for use with people
who have a general chronic disease. There is a
little difference in mean quality of life between
the foot reflexology and control groups at the end
of four weeks of treatment. The evidence relating
to foot reflexology, quality of life and patients with
hypertension did not indicate that foot reflexology

can improve quality of life in patients with hypertension.
However, the results from open-ended questionnaire showed the benefits from these complementary therapies. These results could well reflect the
real benefits of foot reflexology and foot massageto help people feel more comfortable and relaxed,
and improve blood circulation in the feet. The
results are supported by a study by Long, Huntley
& Ernst [18] who surveyed 223 complementary/
alternative medicine organizations about the benefits of complementary therapies, including reflexology and massage. There was a 34% response
rate to their survey, and the results showed that
both reflexology and massage were suitable treatments for relieving stress or anxiety, headaches or
migraines, and back pain.

2- The method of reflexology: This study used
Farnsworth’s method of foot reflexology-‘the
original western modern foot reflexology method’ Dougans [2] . Other studies may have used
different methods, e.g. the eastern foot reflexology method from China, and achieved different results.
3- Small sample sizes, very specific patient group,
limited justification for duration or type of
intervention, and/or untested outcome measures.
Replication with a larger sample of hypertensive
patients is necessary.
Conclusion and recommendations:
This study supported that foot reflexology can
reduce blood pressure levels in patients with hypertension. Future research, which addresses the
limitations of this study, could continue the investigations of these claims. Studies are also needed
to compare reflexology with other complementary/
alternative therapies (e.g., massage, healing touch,
relaxation response), as well as its effect on lipid
profiles in hypertensive patients.

1- Setting: With limited space, the researchers were
unable to have a private room to carry out the
treatments. Treatments were provided in rooms
at the outpatient department where many patients came to see doctors. Sometimes it was
quite noisy. These factors might make it difficult
for participants to feel relaxed and therefore
achieve the desired effect.
