Peripheral Nerve Field Stimulation by Thermal Micro-cautery for Painful Knee Osteoarthritis: Non Randomised Controlled Trial

To trial a traditional pain management technique from Ayurveda in a modern way - the technique involves micro - cautery to painful areas in knee osteoarthritis for patients on a waiting list for knee replacement. The Investigators will include a waiting list control series.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The Research and Ethics Committee at Tallaght University Hospital approved the recruitment of patient into the study by invitation. Patients who accepted the invitation were enrolled into the intervention group and patients who declined the invitation were enrolled into the control group and both groups were followed up for 8 week period. Agnikarma is a traditional surgical technique (thermal cautery) described in ancient surgical manuscripts for the treatment of severe persistent pain.

It applies intense heat to points of maximum pain agreed with the patient pre procedure. The heat is applied by a metal rod (Shalaka) heated in an open naked flame. The rod is applied to the skin at the agreed pain point in an even manner and generates a micro second degree burn. A traditional herbal cream is then applied which cools the application as reported by the patient. It is usual to allow skin healing to occur before the application of further heat (1-2 weeks). The pain points can move within a painful area and the technique best works with precise application to the current pain point. So before each application the precise points are agreed with the patient in advance by demarcating the painful area with a pen and searching for the points of maximum tenderness within that field.

The purpose of this study was simply to define if indeed this technique delivers pain relief as observed in practice. The investigators chose one group to study - painful knee arthritis. In this condition patients often wait many years for the definitive procedure and run some risks with current pain relief treatment. As these patients were not the normal attendees at a pain clinic the investigators decided in advance to limit the study to 4 applications over a 4- 8 week period, the latter to allow for different speeds at which the skin might heal. The investigators recruited both our interventional group and waiting list control group from the same orthopedic waiting list.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention group: PNFS-TMC
Procedure- The patients in the intervention group were examined and the most painful points over the knee with the avoidance of the proposed site for skin incision for a future knee replacement operation were marked. The marked points received an intervention in the form of application of Peripheral Nerve Field Stimulation by Thermal Micro-Cautery (PNFS-TMC), an intense heat by metal rod was applied to the painful points for 0.3 to 0.5 seconds. The patients to receive 4 sessions over a period of 8 weeks with 2 weeks rest after every session.
Other: Peripheral Nerve Field Stimulation by Thermal Micro-Cautery
The most painful points over the knee received an intense heat by a metal rod for 0.5 seconds.
No Intervention: Control group: Stepladder analgesics
Patients with painful knee osteoarthritis and on the waiting list for a total knee replacement surgery and declined to have PNFS-TMC were included in the control group. The control group received the stepladder analgesic protocol for pain management. The analgesic protocol was managed by the orthopaedic team without any interference by the investigators.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in VAS score reduction after 4 sessions
Time Frame: VAS score was recorded every two weeks, after each session with a total of 4 sessions over 8 weeks. 2 weeks interval between sessions
To measure the change in a visual analogue scale is a numerical ruler of 10 cm in length with each centimetre marked and the patient chooses a number between one and ten to score their pain where zero is no pain and 10 is the worst pain that the subject can imagine.
VAS score was recorded every two weeks, after each session with a total of 4 sessions over 8 weeks. 2 weeks interval between sessions

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in activity levels
Time Frame: The objective activity score was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
The change in the activity subjective scores reported by the patient as follow; score 1 means improved , score 2 means worse and score 3 means no change
The objective activity score was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
Change in sleep pattern
Time Frame: The change in the sleep pattern was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
The change in the subjective scores reported by patient as follows, score 1 means improved, 2 means worse and 3 means the same as before
The change in the sleep pattern was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
Change in medication use
Time Frame: The change in the medication use was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
1 means improved as in less use of medication, 2 means worse more use of medication and 3 means the same use of analgesic medication
The change in the medication use was recorded every two weeks after each session with a total of 4 sessions over 8 weeks
