Therapeutic ultrasound associated with copaiba oil reduces pain and improves range of motion in patients with knee osteoarthritis

Abstract

Introduction: Osteoarthritis is a disease that affects millions of Brazilians.Therapeutic ultrasound has been used in its treatment, either alone or associated with drugs. Objective: The aim of this study was to evaluate the effects of ultrasound (US) associated with Copaiba oil (CO) on knee osteoarthritis. Methods: Patients were divided into three different groups: US, US+CO, CO.Ten treatment sessions were held twice a week, 30 minutes each.Pain intensity was assessed through the Visual Analog Scale (VAS) and Range of Motion (ROM) by goniometry, and muscle strength was assessed by means of the Medical Research Council Scale. Statistical analysis was performed by Cohen’s d test, student’s t test and ANOVA, considering p<0.05 as significant. Results: Pain reduced in all groups.The US+CO group (d = -3.50) presented larger effect size when compared to the other groups. Regarding ROM, the largest effect size was observed in the US+CO group for flexion (d = 0.86) and extension (d = 0.97) in comparison with the remainder groups. Muscle strength increased in the US (d = 1.54) and US+CO (d = 1.60) groups for flexion.Regarding extension, the US group presented the largest effect size (d = 1.80). Conclusion: Therapeutic ultrasound associated with copaiba oil is a practical and effective therapy for the treatment of inflammatory diseases such as osteoarthritis.

Effects of therapeutic ultrasound in patients with knee osteoarthritis: A systematic review and meta-analysis

“…We included 21 studies published in English, and the characteristics of the included studies were shown in Table 1 [ [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] ]. These 21 studies reported a total of 1315 participants aged 40–72 years.…”

“…Most of the included studies had small sample sizes, with only 3 studies having more than 40 participants per treatment group [ 40 , 41 , 48 ]. 10 studies were from Turkey [ 32 , 33 , 41 , 43 , 44 , 46 , [49] , [50] , [51] , [52] ]; 3 studies from China [ [38] , [39] , [40] ], and the rest from Egypt [ 35 ], Canada [ 44 ], Iran [ 37 ], Japan [ 42 ], and Brazil [ 36 ]. A detailed Cochrane library assessment tool assessment of the risk of bias was shown in Fig.…”

“…Only 15 trials reported random numbers generated by computer and random enumeration of closed envelopes to generate random sequences [ 32 , [34] , [35] , [36] , [37] , 40 , 42 , 44 , 50 ]. 16 trials described the low risk of allocation concealment [ 32 , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , 44 , 47 , 49 , 50 , 52 ]. Three trials [ 33 , 34 , 48 ] had a high risk of bias when it came to incomplete outcome assessment.…”

“…O ultrassom terapêutico é um dos aparelhos mais utilizados em ambientes fisioterapêuticos, para tratar disfunções musculoesqueléticas e consiste na aplicação de ondas ultrassônicas sobre o tecido, que por meio do seu efeito vibratório proporcionam resultados eficazes no processo de reparação tecidual 14,15 . Estudos acerca da sua aplicabilidade como modo de tratamento vêm sendo realizados há décadas 16 .…”
