Deformation and pressure propagation in deep somatic tissue during painful cuff algometry

Abstract

This study shows the better capability of cuff algometry for stimulation of deep somatic tissue in terms of generation of mechanical stress and strain in contrast to the more superficial muscle tissue previously demonstrated to be strained by single-point pressure algometry.

Tissue mechanics during temporal summation of sequentially cuff pressure‐induced pain in healthy volunteers and patients with painful osteoarthritis

“…All nodes of the bony structures were defined as fixed constraints (Finocchietti et al, 2013;Manafi-Khanian et al, 2015a); i.e. the bones did not have any movement during the simulation, while the nodes of the soft tissue were left free (Manafi- Khanian et al, 2015a,b) to have displacement in space in all directions.…”

“…Previous studies investigating nontime-dependent mechanical behaviour of tissue in single-point (Finocchietti et al, 2013) and cuff algometry (Manafi-Khanian et al, 2015a) have indicated that the skin layer is subjected to the greatest value of stress during the mechanical stimulations.

“…A typical protocol of mechanically painful stimulation for evaluation of TSP is 10 repeated stimuli with 1-s inter-stimulus interval (ISI) (Graven-Nielsen and . Cuff algometry is found to generate an efficient activation of deep tissue structures (Manafi-Khanian et al, 2015a) as compared with single-point algometry (Finocchietti et al, 2011(Finocchietti et al, , 2013, and TSP assessed by cuff algometry shows good reliability (Graven-Nielsen et al, 2015).…”

“…TSP is shown to be facilitated in many different chronic pain patients, e.g. Cuff algometry is found to generate an efficient activation of deep tissue structures (Manafi-Khanian et al, 2015a) as compared with single-point algometry (Finocchietti et al, 2011(Finocchietti et al, , 2013, and TSP assessed by cuff algometry shows good reliability (Graven-Nielsen et al, 2015).

Eficacia analgésica del tratamiento invasivo miofascial (punción seca) en fibromialgia

“…La algometría por presión se considera un método útil para calcular el grado de sensibilización de los tejidos profundos (294). Este método se lleva a cabo mediante un instrumento denominado algómetro, que, en el presente estudio, estaba compuesto por un manómetro adherido a una punta de goma cilíndrica.…”
