Abstract
INTRODUCTION
There are 1.6 billion Muslims in the world, and the act of praying represent a
paramount and fundamental activity of daily living in their community. They need
to adopt several postures that require deep flexion of knee and hip joints to carry out
this daily ritual. The increased demand in the range of motion for the lower limb
joints has been a focus of interest, in the improvement of arthroplasty implants. This
will allow an individual to carry out their responsibility as a Muslim and be well
received in this society. However, there is a lack of data on normative range of
motion studies for the knee and hip joint during Muslim prayers. The intention of
this study was to simultaneously obtain normative passive range of flexion data and
the functional range of flexion during Muslim prayers in the knee and hip joints of
Malay individuals.
METHODS
A cohort of 127 Malay males aged between 20 and 30 years were recruited in this
cross sectional study. Passive range of motion (PROM) and the flexion angle of the
knee and hip joints were measured using a standard goniometer. Demographic and
the range of motion data were collected. The effects of body mass index (BMI),
abdominal circumference (AC) and limb circumferences (LC) on range of motion
were analyzed.
RESULTS
The demographic and range of motion data was tabulated and presented as minimum
and maximum range, mean and standard deviation. The passive range of motion for
the knee and hip joints in this study was comparable to other existing normative
range of motion database. The variables BMI and AC demonstrated a significant
correlation with the knee joint (R2= 0.66). Whereas BMI was the only variable
showing correlation for the hip joint (R2= 0.49 ).
The recorded mean flexion for Muslim prayers was 0.24, 128.52 and 163.59 degrees
for the knee during bowing, prostration and sitting respectively. The mean flexion in
the hip joint for the said movement was 53.67, 92.52 and 75.15 correspondingly.
CONCLUSION
The mean (SD) of the passive knee flexion and passive hip flexion were
141.10(6.60) and 122.10(8.70) degrees respectively which are similar to the values
reported previously in the literature. The BMI had significant correlation with both
the knee PROM as well as the hip PROM, whereas, the abdominal circumference
had only significant correlation for the knee PROM. The limb circumference did not
have any significant correlation with both the knee and hip PROM. The predictive
equation was also obtained by regression analysis to determine the expected degree
of flexion in our local population and is included in the study.
