Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a single session of chiropractic care for the intervention group. The session will take approximately ten minutes. Between the intervention and control session, there is a 1-week washout period. The entire spine and both sacroiliac joints will be assessed for vertebral subluxation, and adjusted where deemed necessary, by a registered chiropractor. The clinical indicators that will be used to assess the function of the spine prior to and after each chiropractic adjustment session include assessing for tenderness to palpation of the relevant joints, manually palpating for restricted intersegmental range of motion, assessing for palpable asymmetric intervertebral muscle tension, and any abnormal or blocked joint play and end-feel of the joints. All of these biomechanical characteristics are used by the chiropractors as clinical indicators of vertebral subluxations. All of the spinal adjustments carried out in this study will be high-velocity, low-amplitude thrusts to the spine or pelvic joints. These are standard adjustment techniques used by chiropractors. The mechanical properties of this intervention has been investigated; and although the actual force applied to the subject's spine depends on the chiropractor, the patient, and the spinal location of the adjustment, the general shape of the force-time history of spinal adjustments is very consistent and the duration of the thrust is always less than 200 milliseconds. The high velocity type of adjustments chosen specifically because previous research has shown that reflex electromyographic activation observed after adjustments only occurred after high velocity, low amplitude adjustments (as compared with lower velocity mobilizations). This adjustment technique has also been previously used in studies that have investigated the neurophysiological effects of chiropractic care.

Rehabilitation
Comparator / control treatment
The control is a single session. The subject’s head and/or spine will be moved in ways that include passive and active movements, similar to what is done by the chiropractor that provide actual chiropractic care during the experimental intervention. Thus this control intervention involves the subject being moved into the adjustment setup positions similar to how the chiropractor would normally setup a subject prior to applying the thrust to the spine to achieve the adjustment. No spinal adjustments will be performed during any control intervention. This control intervention is intended to act as a sham treatment session as well as to act as a physiological control for possible changes occurring due to the cutaneous, muscular or vestibular input that would occur with the type of passive and active movements involved in preparing a subject/patient for an adjustment.

Eligibility
Key inclusion criteria
15-20 participants will be recruited to participate in each of these studies. Participants will be inpatients or outpatients at Shifa International Hospital, in Islamabad or Railway Hospital, Rawalpindi, Pakistan. To be eligible to participate volunteers must suffer from Parkinson's Disease and at least 8 weeks prior to their involvement in the trial and have some ongoing neurological deficit.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Volunteers will be ineligible to participate if they exhibit no evidence of spinal dysfunction, have absolute contraindications to spinal manipulation, have experienced previous significant adverse reactions to chiropractic care, or if they are deemed unsuitable to receive chiropractic care by their treating physicians.

Other design features
To address our hypotheses crossover design, Each participant will attend two study sessions and act as their own controls in a cross-over experimental design. The data from two sessions will be compared to look for changes in SEPs and brain cross-talk (resting state EEG) differences in two sessions. The groups will receive either a control intervention or a chiropractic adjustment intervention during the two sessions they attend. The order of which intervention they receive will be randomized.

Efficacy
Statistical methods / analysis
Descriptive statistics will be reported as mean ± SD. To assess the effect of chiropractic adjustments on the dependent variables a multifactorial repeated measures ANOVA will be used for each of the dependent measures (SEP peak amplitudes, latencies and MMP components), with ‘TIME’ (pre and post intervention measures) and ‘INTERVETION’ (Chiro vs control) as factors. A priori pairwise comparisons of the pre and post intervention data will be carried out when an interactive effect is significant. All statistical analysis will be carried out using IBM SPSS Statistics Version 21.0.0.0 software (IBM Corp, Armonk, NY). Significance will be set at P = 0.05. Repeated measures ANOVA will also be applied to compare MU parameters before and after intervention; and between subjects groups.

Summary
Brief summary
The primary purpose of the study was to assess the changes in sensory inputs of Parkinson's patients following spinal manipulation. Neurodegenerative diseases like Parkinson
effects the s the parts of the brain that are responsible for converting sensory input into meaningful information.
With this study, we wanted to check whether spinal manipulation will be able to change the way parkinson patients process sensory information.
