The study aimed to evaluate the effect of cupping therapy at a clinical setting for knee osteoarthritis. A randomized, controlled clinical trial was conducted. Cupping was performed on 0-6 th day; 9-11 th day and 14 th day, i.e., 11 sittings follow-up to determine longer term carryover of treatment effects utilizing both objective and subjective assessment. The assessment was performed before and after treatment spreading over a period of 15 days. The results of this study shows significant and better results in the overall management of knee osteoarthritis, particularly in relieving pain, edema, stiffness and disability. The efficacy of treatment with cupping therapy in relieving signs and symptoms of knee osteoarthritis is comparable to that of acetaminophen 650 mg thrice a day orally, in terms of analgesia, anti-inflammatory and resolution of edema with minimal and temporary side-effects like echymosis and blister formation while as control drug has greater side-effects particularly on upper gastrointestinal tract. It is recommended that further studies are conducted with a larger study samples and of longer duration. Keywords: Cupping therapy, knee osteoarthritis, regimenal therapy

| Introduction | |  |
Regimenal therapy is a category of treatment modality that utilizes various mechanisms like massage, exercise and leeching etc., to change local and thereafter systemic hemodynamic. Cupping a component of regimenal therapy is utilized for local bloodletting and for local hemo dynamic changes. It ensures enhancement of tissue metabolism by increasing the blood circulation of that site. [1],[2],[3],[4],[5]
These chemical changes through physical procedures and subsequent diversion resulting in excretion from the site or body are known as Imala. [6],[7]
Cupping is of three types; dry cupping is caused by creating a vacuum through mechanical means. Wet cupping utilizes a scarifier to cause bloodletting before or together with dry cupping, whereas, the third type uses fire to create the desired vacuum. [2],[3],[4],[5]
In osteoarthritis, the proteoglycans synthesis rate is brought down from a half-life of weeks to a more rapid one whereas, that of collagen from a half-life of several years to a shorter period leading to chondriocystic loss. This loss is a result of disturbance in the three dimensional framework that holds the proteoglycans in collagen. Hence, there is a failure in repair of both proteoglycans and collagen. [8],[9],[10] Imala has the potential to change the chemical form of the compounds by breaking them into simpler ones and to change their chemical structure for example uric acid accumulated in tissues is changed to ureates or into uric acid excretable through urine. [7],[6]
Osteoarthritis is the most common of all joint disorders and the most expensive in terms of productivity, both in terms of days lost from work and in terms of cost of treatment. Another disadvantage of the disease is the absence of treatment to prevent or ameliorate the basic process. Keeping the effects of cupping in mind the present study was conducted to evaluate the efficacy of cupping in osteoarthritis from a clinical point of view.
| Materials and Methods | | |
Diagnosed cases of knee osteoarthritis attending the Pain Clinic at New Delhi were selected for the study after obtaining their written consent. Patients were randomly allocated either to test Group A or control Group B, The duration of the study was 8 months, whereas the duration of the treatment was 15 days.
A 15-day follow-up was conducted to determine longer term carryover of treatment effects utilizing both objective and subjective assessment. Measurements of subjects were taken pre-and post-test.
Inclusion Criteria
- Subjects with osteoarthritis aged between 30 and 60 years old.
- Subjects who did not receive cupping to the knee region before or to any other region of the body 6 months prior to the study.
Exclusion Criteria
- Subjects with gross deformity.
- Osteoarthritis of joints other than the knee.
The subjects fulfilling the criteria were randomly allotted Group A or B. Group A patients received cupping therapy whereas Group B was given Acetaminophen 650 mg thrice a day orally with water.
Basic Cupping therapy equipment was utilized including a hand suction pump, plastic cups of the same size and anti-septic tools.
The Procedure
The following procedure was adopted while performing cupping:
Prior to commencing application of treatment, we ensured that:
- The subjects had complied with the pre-cupping requirements (inclusion criteria).
- Contra-indications were eliminated
- Equipment was sterilized
- Subjects were explained and subsequently reassured regarding the temporary and minor side-effects such as echymosis and blister formation.
- As per surface anatomy dry cupping was done on vastus lateralis, vastus intermedius, tibialis anterior and biceps femoris insertion laterally, medially it was done on tendons of Sartorious, gracilis and semitendinosus inferiorly and superiorly on vastus medialis [11] for 15 min.
- Cupping was done on 0-6 th day; 9-11 th day and 14 th day, i.e., 11 sittings in all.

| Discussion | | |
Cupping on the said sites ensured erythema, ecchymosis, release of sebum, water vapor and even blister formations. The erythema and ecchymosis were circular in shape and were directly proportional with symptomatic improvement. Blisters too appeared on the anterio medial aspect of the knee. The blisters gave the characteristic burning sensation and appearance of pressure blister. These varied in number from two to three to plentiful, i.e., 15 with straw colored fluid. The blisters were ruptured under aseptic conditions with a sterile needle. No further treatment was necessary for the blisters. The fluid from such blisters varied from 0.05 ml to 0.2 ml per sitting. The blistered site was given rest for a day or two for healing. The knee improved dramatically after blister formation especially in terms of edema, crepitations and stiffness. Blisters usually formed after 4 to 5 days of cupping. The blisters formed easily and larger in numbers during summers and under increased room temperature. Individuals reacted differently to the same amount of pressure, time of application and room temperature. Some gave severe ecchymosis where as others had blisters [Table 5] and Graph 5 [Additional file 12] while some other had no changes at all. This difference in reaction can be attributed to:
- Personal temperament
- Temperament of the Ma-adda ghair mehmooda or metabolites.
- Fat deposition in the area. The fats deposited are inversely proportionate to the ecchymosis, blisters, etc.
- The severity of disease - the amount of metabolites accumulated or the pathological changes since cupping ensures imala, the more the metabolites the more time is spend in diversifying them.
- History of prior cupping - if the patient had been undergoing cupping for some time his metabolites are already in a state of movement.
- Bathing or perspiration - if the patient has had a bath prior to cupping session. The water absorbed by the skin during bathing or post perspiration is excreted in the form of blisters during cupping sessions.
- Local use of anti-inflammatory drugs - the anti-inflammatory drugs too cause a change in the metabolitic status of the joint.
The hemodynamic changes brought about through dry cupping are evident from ecchymosis and blister. These biochemical changes that resulted from vacuum are signs of imala. The vacuum pulls the muscle beyond its normal elastic limits and causes breeches in microvasculature of that area ensuring local hyperemia. Thus increasing the blood supply in the capillary system of that specific site. The metabolites that are diversified from the bony tissue towards muscle are taken up by the phagocytes from these capillary beds.
The patients on cupping therapy showed better results terms of pain, morning stiffness, tenderness, edema, crepitations and movement disability when compared with those on acetaminophen. However, patients of acetaminophen responded well to nocturnal pain when compared to those on cupping therapy.
The ecchymosis and blister formation are directly related to the duration and volume of negative pressure created by cupping and are usually the only undesired effects of cupping therapy for the patient besides causing a mild pain during the cupping session due to indrawing of tissues because of suction effect. But when the patient is taken into confidence and informed in advance of such effects and ensured about their transient nature than the patients are not bothered by their occurrence.
| Conclusion | | |
The study proved cupping to be a good analgesic and anti-inflammatory with efficacy better than acetaminophen. Thus, cupping can be recommended for other painful conditions besides being a line of treatment for osteoarthritis.
Cupping superimposes acute inflammation on chronic inflammation. The chronic inflammation of cartilage that is deep seated has acute inflammation on the skin and muscles. A study conducted by Pete et al. in Poland states that degenerative changes occurs as a result of decreased blood supply. Acute inflammation at a site 1-3 mm from the affected joint does improve the blood circulation of the site for a sustained period of 11 days shows the desired changes.
The effect of this at proteoglycans and collagen level needs evaluation to understand the pharmokinetics of vacuum of healthy and ailing tissue another aspect that needs further attention is the concept of healing by causing acute inflammation in tissue superior to chronic inflammation.
The initial increase in pain in Grade 3 and Grade 4 must be because the pain of osteoarthritis had restricted the use of these muscles and thereby causing a loss in their elasticity hence the additional burden on the elasticity caused pain.
Cupping also proved to be a good exercise to specific muscles besides improving their blood supply.
