Objective(s)
To investigate the efficacy of whole-body vibration intervention in improving outcomes
in patients with patellofemoral pain syndrome.
Data Sources
We performed an electronic literature search through four databases from inception
until August 14, 2022.
Study Selection
We imported records into the Mendeley software and checked for duplicates, then performed
an eligibility screening against our inclusion criteria through two main phases: title
and abstract screening and then full-text screening.
Data Extraction
Two independent authors extracted the required data from included articles and performed
a quality assessment by using the Pedro scale for these studies.
Data Synthesis
We included five studies according to our selection criteria, with 180 participants.
The participants suffered from either unilateral or bilateral patella-femoral pain.
the studies compared whole-body vibration versus conventional exercises. Regarding
pain, the pooled analysis of five studies didn't show significant inter-group differences
(pooled standardized mean difference (SMD) - 0.93; 95% confidence interval (CI) -
1.973 to 0.122; P = 0.083). The meta-analysis of four studies didn't show a significant
difference between the application of whole-body vibration and conventional exercises
concerning knee function (pooled standardized mean difference (SMD) - 0.93; 95% confidence
interval (CI) -0.109 to 0.122; P = 0.083). Moreover, the pooled effect size of the
two studies didn't conclude significant inter-group difference regarding the mental
component summary of the quality of life (pooled standardized mean difference (SMD)
0.260; 95% confidence interval (CI) -0.212 to 0.732; P = 0.280). Concerning the physical
component summary of the quality of life, the pooled analysis of two studies showed
significant results compared to conventional exercise (pooled standardized mean difference
(SMD) 0.640; 95% confidence interval (CI) 0.159 to 1.121; P = 0.009).
Conclusions
The use of whole-body vibration could improve the physical component summary of the
quality of life of patients with patellofemoral pain. However, regarding pain, knee
function, and the mental component summary of the quality of life, the application
of whole-body vibration seems to be similar to the use of conventional exercises.
