Evaluation of repetitive Muscle Magnetic Stimulation (rMMS) effects on functional status and quality of life after knee surgery.
Ultrasound (US) and Elastosonography,
as well as Visual Analog Scale (VAS),
Maximal Voluntary Contraction (MVC) and Short Form Health Survey (SF-36) assessment were performed.
Methods and Materials
A 55 year old female patient underwent knee surgery reporting a severe quadriceps muscle (QM) group atrophy showing no improvements after 11 months of rehabilitative physiotherapy.
Patients with Knee disorders exhibit a decreased activation of quadriceps compared to the uninvolved limb suggesting that neural mechanisms contribute to the weakness of the quadriceps.
Weakness of the quadriceps muscle results in important functional consequences such as decreased gait speed,
difficulty with stair climbing,
and rising from a chair and risk of falls.
After the cessation of...
Transverse and longitudinal US acquisitions were performed by the same expert sonographer at T0 and T1,
following the same protocol.
the right foot was always the first to be scanned and the US images were performed with the probe in both longitudinal and transversal positions.
B-mode US acquisitions were performed on both legs.
They were examined in the same area,
in order to have a direct comparison between the injured (DX) and healthy (SX) leg.
Re-positioning of the probe in almost exactly the same...
rMMS has demonstrated improvements in muscle function parameters in COPD patients (Bustamante et al.
but to the best of our knowledge no data are available in patients with muscle strength reduction after knee surgery.
The use of rMMS was effective at providing rapid improvements in strength,
knee pain and quality of life,
and morphological and structural muscle changes have been documented by means of B-Mode US and elastosonography.
A portable US system capable of elastosonography with a high level of image quality was used...
