简要总结
The objective of this study is to determine if one single X-ray-guided intradiscal injection of 8 mg/mL of HYALODISC combined with PEP will be more effective than only physical exercise program in patients with LBP from degenerative disc disease.
Enrolled patients will be randomly assigned to one of the two treatment groups below:
- Group 1: One single X-ray-guided intradiscal injection (25 gauge) of 8 mg/mL of HYALODISC combined with PEP. The investigator will use one syringe for each involved disc, up to a maximum of three discs.
- Group 2: PEP alone. The injection will be administered at V1 baseline (day 0). Any physical activity (e.g. jogging, tennis, weightlifting, prolonged upright position) in the 48 hours following the injection should be avoided.
Both groups (Group 1 and Group 2) will be treated with PEP according to a standardized protocol. Starting one week after the baseline visit (V1), patients will be prescribed of 18 physiotherapy sessions that will take place under supervision of physiotherapist twice a week in the first seven weeks (weeks 2-8) and once a week in the next four weeks (weeks 9-12). Twelve repetitions of each exercise for 3 sets will be performed during PEP session. Moreover, in addition to the 18 sessions performed with supervision of the physiotherapist, all patients will be instructed how to do exercises at home and will be asked to continue these exercises once a week in the first seven weeks (weeks 2-8) and twice a week in the next four weeks (weeks 9-12).
详细描述
During the inclusion visit (V0) upon signature of the informed consent, eligible subject will be enrolled. At baseline visit (V1) eligible subjects will then randomly assigned to 1 of 2 treatment groups: HYALODISC + PEP (Group 1) or PEP alone (Group 2). At baseline visit (V1) HYALODISC (8 mg/ml) will be administered to group 1. The investigator will use one syringe for each involved disc, up to a maximum of three discs. The maximum volume that could be injected is 1.5 mL for each disc involved.
The PEP session will start for both groups one week after V1. Randomized subjects will follow the instructions during the PEP session, for a total of 18 sessions that will be performed under supervision of physiotherapist twice a week in the first seven weeks (weeks 2-8) and once a week in the next four weeks (weeks 9-12). Twelve repetitions of each exercise for 3 sets will be performed during PEP session. Moreover, all patients will be instructed how to continue these exercises at home, where the execution will be once a week in the first seven weeks (weeks 2-8) and twice a week in the next four weeks (weeks 9-12). Patients in group 2 that still present low back pain score > 6, despite the PEP, at the physical examination at V3 (12 weeks after V1), could be treated with HYALODISC intradiscally. Those patients will be then evaluated at 12 weeks after the treatment (week 24).
Follow-up visits are set at 4, 12 and 24 weeks (V2, V3 and V4)
