Abstract
Objectives
To compare the effects of Liuzijue Qigong and conventional respiratory training on
trunk control ability and respiratory muscle functions in patients at an early recovery
stage from stroke.
Design
A single-blind, randomized controlled trial.
Setting
A hospital.
Participants
Patients (N=60) within 2 months poststroke.
Interventions
The experimental group (n=30) received conventional rehabilitation training combined
with Liuzijue exercise, and the control group (n=30) received conventional rehabilitation
training combined with conventional respiration training. The training in the 2 groups
was conducted 5 times per week for 3 weeks.
Main Outcome Measures
Trunk Impairment Scale (TIS), maximum inspiratory pressure (MIP), maximum expiratory
pressure (MEP), forced expiratory volume in the first second (FEV1), forced vital
capacity (FVC), peak expiratory flow (PEF), maximum expiratory mid-flow (MMEF), diaphragmatic
movement, the change of intra-abdominal pressure (IAP), Berg Balance Scale (BBS),
and Modified Barthel Index (MBI). All outcome measures were assessed twice (at baseline
and 3 weeks).
Results
Both groups significantly improved in TIS, MIP, FVC, PEF, and the change of IAP, BBS,
and MBI when pre- and postassessments (P<.05) were compared. Compared with the control group, there was a significant difference
in the experimental group in the static sitting balance subscale (P=.014), dynamic balance subscale (P=.001), coordination subscale (P<.001), TIS total scores (P<.001; effect size [ES]=0.9), MIP (P=.012; 95% confidence interval [CI], 2.23-17.69; ES=0.67), MEP (P=.015; 95% CI, 1.85-16.57; ES=0.65), change of IAP (P=.001), and MBI (P=.016; 95% CI, 1.51-14.16; ES=0.64). No significant differences were found between
the 2 groups in FEV1 (P=.24), FVC (P=.43), PEF (P=.202), MMEF (P=.277), the diaphragmatic movement of quiet breathing (P=.146), deep breathing (P=.102), and BBS (P=.124).
Conclusions
Liuzijue exercise showed more changes than conventional respiratory training in improving
trunk control ability, respiratory muscle functions, and activities of daily living
ability in patients at an early recovery stage from stroke.
