Outcomes
for ARP treatment have been based, thus far, on retrospective clinical
observations. Randomized, double blinded, prospective studies have been
initiated for the treatment of ankle sprains, hamstring injuries, and
distal radius fractures. The hypotheses for these prospective studies
is that ARP treatment will yield recovery rates 60% to 80% faster than
for traditional conservative treatment.
The
basis for these hypotheses is the large retrospective clinical data on
ARP treatment over the past 5 years. In general, recovery rates for
acute soft tissue injury have been 60% to 80% shorter than the
predicted clinical outcome. Specific examples include grade II lateral
ankle sprains, and grade II acute hamstring injury.
Athletes
sustaining grade II lateral ankle sprains (partial ligament tear with
moderate swelling and ecchymosis and limited weight bearing ability)
treated with 6 to 10 ARP sessions, and no other conservative treatment
except supportive bracing, had an average recovery rate and return to
play at 3 to 5 days post injury. Athletes sustaining grade II hamstring
injuries (1-2cm soft tissue defect with associated ecchymosis and
inability to walk without limp) treated also with 6 to 10 ARP sessions,
without other modalities, had an average recovery rate and return to
play at 8 to 12 days post injury.
These
accelerated recovery rates also extrapolated to the more severe grade
III injuries, as well as chronic soft tissue tendinopathies. In many
cases of chronic tendinopathy, all other conservative measures were
exhausted, without relief of symptoms, before ARP treatment was
initiated.
The ARP
experience has produced a sense of astonishment among both the
practitioner and the patient. Undoubtedly, prospective data will be
required to corroborate these retrospective findings, but it is
certainly clear that the rate of acceleration in healing has been
dramatic.
