Arm Description

High frequency TMS will be applied with an eight-shaped coil angled at zero degrees from the sagittal axis and positioned at the C3 or C4 in accordance with the international 10-20 marking system (JASPER, 1958), which corresponds to the right or left primary motor cortex (M1). Twenty four stimulus trains will be provided at 10 Hz for five seconds each. The interval between the trains will be 25 seconds, totaling 1200 pulses for approximately 12 minutes, with 90% of resting motor threshold (RMT). After TMS, patients will be submitted to 45 minutes of manual therapy protocol.

Patients will be submitted to 45 minutes of manual therapy protocol. After that, high frequency TMS will be applied with an eight-shaped coil angled at zero degrees from the sagittal axis and positioned at the C3 or C4 in accordance with the international 10-20 marking system (JASPER, 1958), which corresponds to the right or left primary motor cortex (M1). Twenty four stimulus trains will be provided at 10 Hz for five seconds each. The interval between the trains will be 25 seconds, totaling 1200 pulses for approximately 12 minutes, with 90% of resting motor threshold (RMT).

In this group, the order of interventions will be randomized. Therefore, the volunteer can start with manual therapy or sham TMS. In manual therapy, patients will be submitted to 45 minutes of a protocol. In addition, with regard to sham TMS, the same parameters will be used, however, it will be performed using two coils, one connected to the magnetic stimulator, away from the patient's scalp and another uncoupled from the stimulator and positioned in the same way as in real stimulation.

Outcomes

Primary Outcome Measures

Pain
Pain will be evaluated by pressure algometry before and after the interventions. It's a evaluation technique which aims to quantify through physical stimulation (pressure in the nociceptors) the capacity of pain perception and toleration. It will be used with the patient lying in supine and will have the purpose of measure the pressure pain threshold (PPT) in eight points around patellar region. Besides that, two control points will be adopted, one in anterior tibial muscle (five centimeters distal of anterior tibial tuberosity) and another in the extensor carpi radialis longus muscle (five centimeters distal to lateral humerus epicondyle). After marking, the algometer will be setted up 90° in contact with the skin and will be applied a 0,3 kgf/cm²/s pressure until the patient report pain by pressing a pen (Model/Brand: Algomed/Medoc). The measure will be done twice in the demarcated points with a two minutes interval between them. Will be considered a mean of the obtained values.
Pain Rating Scale (NPRS)
Is it used to quantify pain level, where 0 means no pain and 10 means worst pain possible. NPRS is recommended as the main endpoint in chronic pain studies and it has been established that a decrease of at least 2 points or 30% represents a minimal clinically important difference. The MDCI consists of the smaller variation in a clinical outcome perceived by the patient and that results in a relevant change in his state of health.

Secondary Outcome Measures

Cortical excitability
The motor evoked potential (MEP) will be provided by twenty unconditioned stimuli (120% of motor resting threshould).

5. Study Description

Brief Summary
In this study, the investigators wondered whether the association between high frequency repetitive transcranial magnetic stimulation (hf-rTMS) and manual therapy (peripheral and central approach) is more effective in reducing pain levels and modulation of cortical activity of chronic knee ostearthritis pain subjects than manual therapy alone (usual peripheral approach). For this purpose, patients included will be submitted to one session with active or sham hf-rTMS followed by a protocol of manual therapy. Besides that another active group will have the sequence of interventions exchanged (manual therapy followed by hf-rTMS) in order to investigate whether this may influence in the final outcomes.

Intervention Name(s)
TMS
Other Intervention Name(s)
non invasive brain stimulation, high frequency TMS
Intervention Description
Repetitive TMS involves application of electric currents in the patient's cortex by a magnetic field applied to the scalp of the patient through an eight-coil connected to a magnetic stimulator (MagStim Rapid² magnetic stimulator-UK). In a small percentage of patients, it may cause minimal discomfort with a mild headache sensation, which usually disappears after a few seconds. Depending on the parameters, rTMS can increase or decrease corticomotor excitability and by the connection of the motor cortex with the thalamus, influencing pain control. The patients will respond to an adverse effects questionnaire and will report the perception of real or sham stimulation.
Intervention Type
Other
Intervention Name(s)
Manual therapy (MT)
Other Intervention Name(s)
Musculoskeletal manipulation
Intervention Description
This intervention uses manual contact for diagnosis and treatment, its practitioners use an enormous amount of manual techniques to preserve the homeostasis through the recovery of dysfunctions, which may cause limitations in the physiological movements, in the accessory movements of the joints (WHO , 2010).
