Given that OA has no cure, and self-management with exercise and physical activity is a core recommended management strategy, physiotherapists are important providers of care. As with all healthcare professionals, physiotherapists are responsible for ensuring that the OA care they provide is safe and aligns with best practice Intermittent vacuum therapy -IVT- was developed by NASA based on the LBNPD procedure (lower body negative pressure device). This kind of therapy is used to treat vascular diseases of the legs, to accelerate rehabilitation of athletes, to reduce edema in the lower extremities, to treat cellulite as well as other indications. The device for intermittent vacuum therapy consists of a cylindrical chamber into which the lower body of a patient is placed. The patient is lying on his back, his legs and lower body up to the crest of the iliac bone are inside the chamber. In the area of the waist, the chamber enclosing the lower body of the patient is sealed using a diaphragm. A vacuum pump generates negative pressure in the chamber. The device generates intermittently negative and normal pressure. Under the effect of the vacuum, blood from the area with relatively high pressure (upper body outside the chamber) flows into the area of lower pressure (lower body inside the chamber), thus improving blood circulation in the lower extremities. Due to the blood flow towards the lower extremities, the mean blood pressure falls. Normally, the body compensates for the redistribution of blood by increasing the pulse rate and peripheral vascular constriction. Due to the blood flow towards the lower extremities, the mean blood pressure falls.

AIM:- To study the comparative effects of IVT & conventional physiotherapy in the management of Knee Osteoarthritis

OBJECTIVES:- 

1. To assess the effects of IVT along with Conventional protocol on a decrease in pain, increase in ROM, and functional activity in Knee Osteoarthritis 

2. To assess the effects of Conventional therapy on the decrease in pain, increase in ROM, and functional activity in Knee Osteoarthritis

3. To compare the effects of both in patients with Knee Osteoarthritis.
