To the Editor:
I read “Early Quadriceps Strength Loss After Total Knee
Arthroplasty”, (JBJS,87A,1047-1053), hoping to find relevent clinical
application. Identifying failure of voluntary muscle activation, the
authors may have inadvertently provided a scientific rationale for an
empirically effective post op technique that my patients describe as
cruel, albeit while laughing.
It is my routine to tickle the ipsilateral foot post op TKR, usually
eliciting a robust quadriceps contraction, some pain and usually a laugh.
If done artfully, patients accept this treatment, as it literally
“jumpstarts” recovery of the quadriceps. It works well but only in those
who are ticklish. Many family members eagerly take part with this
treatment. Patients are motivated to avoid the tickle technique by doing
the quad contraction on their own, and moving the leg to avoid the noxious
irritant. Counterintuitively, pain avoidance and “very rapid mobilization”
can be beneficially combined to improve voluntary and involuntary
quadriceps muscle activation.
Might I suggest study of this technique as
a clinical application suitable for the authors continuing research?
