Brief Summary

Parkinson's disease (PD) is the second commonest neurodegenerative disorder, affecting over 145,000 people in the UK. Initially, PD patients experience slowness of movements, limb stiffness, and tremor. With progressive loss of neurons over time, many patients start to experience balance and walking problems, and falls, which are resistant to currently available treatments. Falls can lead to fractures and nursing home admission, and can significantly shorten patients' life expectancy. In this pilot study, the investigators will investigate the effects of spinal cord stimulation (SCS) on gait and balance in PD. Some open-labelled studies have shown possible beneficial effects of SCS in PD, although it is uncertain which type of PD patients will benefit most and which stimulation parameters work best. The investigators will assess the effects of SCS on posture and gait using a series of clinical, laboratory, imaging, and wearable measurements. The participants will receive a percutaneous implantation of a spinal cord stimulator to minimise the possible adverse effects related to the surgery. The SCS will start one month after surgery. The investigators will use a double-blind cross-over design. The participants will receive three different stimulation parameters, including sham stimulation, in a randomised order. The participants and the assessors will be blinded to the stimulation parameters.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants with Incidence of Treatment-Emergent Adverse Events

    Safety of a 28-week SCS Intervention will be assessed by measuring the number of participants with adverse events that are related to treatment

    Day 1 post-surgery, week 6 post-surgery, week 12 post-surgery, week 18 post-surgery, week 28 post-surgery

  • Number of Participants with Incidence of Serious Adverse Events

    Safety of a 28-week SCS Intervention will be assessed by measuring the number of participants with serious adverse events

    Day 1 post-surgery, week 6 post-surgery, week 12 post-surgery, week 18 post-surgery, week 28 post-surgery

  • Number of Participants that complete the study

    Safety of a 28-week SCS Intervention will be assessed by measuring the number of participants that complete the study

    Day 1 post-surgery, week 6 post-surgery, week 12 post-surgery, week 18 post-surgery, week 28 post-surgery
