More than 170 studies of reflexology's
effects have been conducted with 90% showing
a positive result. Effectiveness was demonstrated
as symptoms were ameliorated for
health concerns stemming from tension (e. g.
elevated blood pressure, anxiety, constipation,
headaches, labor times for the pregnant)
and pain relief. Further responses (e. g. for
those with asthma, diabetes, cholesterol,
incontinence) were found to require an
appropriate number and frequency of sessions.
