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.

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

Study Arms (3)
High Frequency SCS
ACTIVE COMPARATORParticipants will be randomly assigned to this arm for up to 6 weeks
Burst SCS
ACTIVE COMPARATORParticipants will be randomly assigned to this arm for up to 6 weeks
Sham SCS
SHAM COMPARATORParticipants will be randomly assigned to this arm for up to 6 weeks
Interventions
High Frequency-SCS consists of delivering electrical stimulation at frequencies equal to or greater than 1kHz. This intervention will last up to 6 weeks.
Burst SCS consists of closely spaced, high frequency stimuli delivered to the spinal cord. This intervention will last up to 6 weeks.
