Abstract: Aim: To evaluate the effects of whole-body vibration in the sciatic nerve of oophorectomized Wistar rats, on nociceptive and morphological parameters, such as fiber, axon, and myelin sheath diameters, G ratio, number of nerve fiber and nuclei of Schwann cells, and percentage of connective tissue. Method: Sixty-four rats were used in the groups sham-operate and oophorectomy (n = 32/group); after surgical procedures, each group was subdivided into four: euthanized in the 12 th week, untreated and treated for fou… Show more

“…For the remobilization of the WG using WBV, we utilized the commercial platform Vibro Oscillator Arktus Triplanar Professional ® , with a frequency of 60 Hz and vibrations with an amplitude of 2 mm. The exercise protocol was adapted from Kakihata et al (2019), which consisted of an exposure period of 10 min/day, 5 days a week, being done for 2 weeks. To accomplish this, we placed the animals on the platform using a divider that allowed the positioning of eight animals simultaneously in stalls 13 cm wide, 19 cm long, and 25 cm high.…”

“…It is known that high-intensity vibrations are responsible for muscle injuries, pain in the back, and joints 17 . Conversely, in a study 24 with oophorectomized rats, WBV for four and eight weeks did not change the nociceptive threshold. Still, studies in humans pointed out that WBV was able to reduce low back pain, osteoarthritis, joint and muscle pain 19 .…”

“…A wooden support (MDF) was used, which allowed positioning eight animals simultaneously in stalls with 13cm (width), 19cm (length), and 25cm (height). There was a rotation of the stalls during the treatment 24,25 to minimize a possible bias on different points of acceleration and amplitude on the vibrating platform (Figure 3). The assessment of the nociceptive threshold was performed using a digital analgesiometer, Von Frey filament-like, from Insight ® (Ribeirão Preto, SP, Brazil).…”

“…9 WBV After 15 days of immobilization, the removal of the immobilization was done, and on the 16th day the remobilization protocol was started, being the free remobilization for G3 and remobilization on the Vibrooscillatory Arktus triplanar professional commercial platform, with a frequency of 60 Hz and vibrations with an amplitude of 2 mm for G4. 17 G4 rats were contained in the platform by a device, constructed in white MDF, with a total area of 25.4cm² subdivided into eight bays with 13 centimetres wide, 19 centimetres long and 25 centimetres high, with rotation of animals to each application, so that the same rat did not always remain in the same bay; the daily duration was 10 minutes, three days intercalated per week, completed after 2 consecutive weeks. G2 animals were euthanized immediately after removal of the immobilization apparatus.…”
