Resumo
Knee osteoarthritis (OA) is one of the most common progressive degenerative joint
diseases worldwide and also a major cause of disability and damage to quality of life.
Photobiomodulation therapy (PBMT) through low-level laser, isolated or in association
with physical exercise has shown to be a promising treatment and with good results
for several chronic diseases, including changes that affect the articular system. The
aim of this study was to evaluate the effects of laser PBMT applied to acupuncture
points associated with a resistance exercise protocol on the level of pain in women
with OA. 23 volunteers were randomized into 2 groups: Control group (Ex): volunteers
were submitted to a resistance exercise protocol; Photobiomodulation Group (ExP):
volunteers were submitted to a resistance exercise protocol associated with PBMT
applied in acupuncture points. The interventions were performed twice a week for a
period of 6 weeks, totaling 12 sessions. The exercise program consisted of warming
up, muscle strengthening (hip and knee flexors and extensors, hip adductors and
adductors) and stretching of the main muscle groups of the lower limbs (lower limbs).
PBMT (808 nm, 100 mW, 4 J in) was applied to 5 acupuncture points of the affected
knee right after each exercise session. For assessment and reassessment, the
numerical rating scale for pain (NRS) was applied; functionality and quality of life
questionnaires (Western Ontario and MacMaster Universities Osteoarthritis Index
[WOMAC]); functionality (Lequesne); physical performance tests (Timed Up and Go
[TUG], Short Physical Performance Battery [SPPB]), lower limb strength and
endurance (30-second sit-up test). The results show that both Ex and ExP showed a
lower rate of pain, higher scores in the tests of strength and endurance, in functionality,
in physical performance, mobility and balance and in WOMAC to its initial rates when
compared to the final ones. However, no difference was observed between the
experimental groups. Thus, it can be concluded that both PBMT in specific
acupuncture points in association with physical exercise, as well as applied exercise
in isolated way, show analgesic effects and have positive effects on physical capacity
and quality of life in patients with OA.
