ABSTRACT
PURPOSE:
Intractable upper limb and neck pain has traditionally been a challenging pain condition to treat, with conventional spinal cord stimulation (SCS) often inducing positional variation in paraesthesia and/or inadequate coverage of axial neck pain. The purpose of this Australian multi-centre prospective, clinical trial was to assess the safety and effectiveness of paraesthesia-independent 10 kHz SCS for the treatment of upper limb and neck pain.METHODS:
Subjects with chronic, intractable neck and/or upper limb pain of ≥ 5 cm (on a 0-10-cm visual analogue scale) were enrolled (ACTRN12614000153617) following human research ethics committee approval. Subjects were implanted with two epidural leads spanning C2-C6 vertebral bodies. Subjects with successful trial stimulation were implanted with a Senza® system (Nevro Corp., Redwood City, CA, USA) and included in the safety and effectiveness evaluation at 3 months post-implant (primary endpoint assessment, PEA) and followed to 12 months.RESULTS:
Overall, 31/38 (82.6%) subjects reported a successful 10 kHz SCS trial and proceeded to a permanent implant. Twenty-three of 30 subjects (76.7%) met the PEA. Subjects reported a reduction in neck pain and upper limb pain from baseline at the PEA (8.1 ± 0.2 cm vs. 2.9 ± 0.5 cm, 7.3 ± 0.3 cm vs. 2.5 ± 0.5 cm, respectively, p ≤ 0.0001). Disability, as measured by pain disability index score, decreased from 42.6 ± 2.6 at baseline to 22.7 ± 3.2 at PEA. Results were maintained 12 months post-implant. No neurological deficits, nor reports of paraesthesia, were observed.CONCLUSIONS:
Stable, long-term results demonstrated that 10 kHz SCS is a promising therapy option for intractable chronic upper limb and neck pain.Palabras clave
