The aim of this experimental study was to assess whether 5 weeks of preoperative supplementation with vitamin D affects the intensity of pain and the level of inflammatory markers in patients undergoing posterior lumbar interbody fusion (PLIF) followed by rehabilitation. 42 patients were divided, by double-blind randomization, into two groups: supplemented (SUPL) vitamin D (3200 IU dose of vitamin D/day for 5 weeks) and placebo group (PL) treated with vegetable oil. The 10-week program of early rehabilitation (3 times a week) was initiated 4 weeks following PLIF. Measurements of serum 25(OH)D 3 and CRP, IL-6, TNF-α, and IL-10 were performed. Pain intensity was measured using VAS. After supplementation with vitamin D serum, the concentration of 25(OH)D 3 significantly increased in the SUPL group ( ∗ p < 0.005) and was significantly higher as compared to the PL group ( ∗ p < 0.001). A significant reduction in pain intensity was observed 4 weeks after surgery and after rehabilitation in both groups. In the SUPL group, serum CRP and IL-6 concentration significantly decreased after rehabilitation, compared with the postsurgical level ( a p < 0.04). The level of TNF-α was significantly lower after rehabilitation only in the supplemented group ( ∗ p < 0.02). There were no significant changes in the IL-10 level in both groups during the study. Our data indicate that supplementation with vitamin D may reduce systemic inflammation and when combined with surgery and early postsurgical rehabilitation, it may decrease the intensity of pain in LBP patients undergoing PLIF. Data indicate that LBP patients undergoing spine surgery should use vitamin D perioperatively as a supplement.
Background: The introduction of early rehabilitation exercise is the foundation of treatment post-Posterior lumbar interbody fusion (PLIF) surgery, and the search for additional sources of reinforcement physiotherapy seems to be very important. Methods: The patients were randomly divided into the vitamin D3 (n = 15; D3) supplemented group and received 3200 IU per day for five weeks before surgery and the placebo group (n = 18; Pl) received vegetable oil during the same time. The patients began the supervisor rehabilitation program four weeks after surgery. Results: The limits of stability (LOS) were significantly improved in the D3 group after 5 and 14 weeks (p < 0.05), while in the Pl group, progress was only observed after 14 weeks (p < 0.05). The LOS were also higher in the D3 group than in the Pl group after five weeks of supervised rehabilitation (p < 0.05). In the postural stability (PST) test, significant progress was observed in the D3 group after 14 weeks (p < 0.02). In addition, neither rehabilitation nor supplementation had significant effects on the risk of falls (RFT). Conclusions: Vitamin D supplementation seems to ameliorate the effects of an early postoperative rehabilitation program implemented four weeks after posterior lumbar interbody fusion. Early physiotherapy treatment after PLIF surgery combined with vitamin D supplementation appears to be a very important combination with regard to the patients’ recovery process.
Introduction. Osteoporosis and osteopenia are related to changes in the quantity and quality of skeletal muscle and contribute to a decreased level of muscle strength. The purpose of this study was to evaluate the impact of Nordic walking training on muscle strength and the electromyographic (EMG) activity of the lower body in women with low bone mass. Material and methods. The participants of the study were 27 women with low bone mass. The sample was randomly divided into two groups: a control group and an experimental group. Women from the experimental group participated in 12 weeks of regular Nordic walking training. Functional strength was assessed with a 30-second chair stand test. The EMG activities of the gluteus maximus (GMax), rectus femoris (RF), biceps femoris (BF), soleus (SOL), and lumbar (LB) muscles were measured using a surface electromyogram. Results. Nordic walking training induced a significant increase in the functional strength (p = 0.006) of the lower body and activity of GMax (p = 0.013) and a decrease in body mass (p = 0.006) in women with reduced bone mass. There was no statistically significant increase in the EMG activities of the RF, BF, SOL, or LB muscles. The study did not indicate any significant changes in functional muscle strength, the EMG activity of the lower body, or anthropometry in women from the control group. Conclusions. Nordic walking training induces positive changes in lower body strength and the electromyographic activity of the gluteus maximus as well as a decrease in body mass in women with low bone mass.
