Immediately after patients undergo total hip arthroplasty (THA), they
are often coached through the process of rising from the bed to prevent
dislocation. However, motion analysis of this process, which can guide coaching
methods, has not been conducted. The purpose of this study was to clarify whether
there is a difference in hip joint angle, rise time, pain, and difficulty based
on the method of rising from the bed in postoperative patients, immediately after
THA. METHODS: Twenty patients who underwent THA were enrolled in this study.
Seven days after surgery, 3-D motion analysis was performed while subjects rose
from the bed using six different methods that include rising from the bed using
either the affected or non-affected side either with or without assistance. Hip
joint angle, rise time, pain, and difficulty were evaluated. RESULTS: In all six
methods, the maximal hip joint angle of the affected side was in the safe range.
The maximal hip adduction angle and adduction angle at maximum flexion of the
affected side were significantly lower in patients who rose from the bed using
their affected side than in those who rose using their non-affected side. There
were no differences in maximal hip flexion angle, internal rotation angle,
internal rotation angle at maximum flexion of the affected side, rise time, pain,
or difficulty regardless of the direction of rising from the bed or the use of
assistance. SIGNIFICANCE: Coaching patients to rise from the bed is better
performed when using the most optimal method that takes into consideration the
movement direction and patient's individuality.
