A pneumomassage device comprising: a pneumomassage sleeve adapted to fit onto a first and a second adjacent body parts and an anatomical joint therebetween, said sleeve comprising: a proximal section that is adapted to conform to the first body part; a distal section that is adapted to conform to the second body part; and a joint section between said proximal section and said distal section that is configured to conform with the anatomical joint, an effective Length (L p1; L p2) of proximal section is composed of length (L p) of the proximal section and a length (L hp1; L hp2) of a portion of the joint section coaxially aligned with proximal section, and extending from a proximal end to a bend of the joint section, and a releasable securing assembly comprising: a first coupling element and a second coupling element, wherein said first coupling element is configured for coupling to said second coupling element; characterized in that the first coupling element is coupled to and extends outward from an outer surface of said proximal section of the sleeve; and the second coupling element is coupled to and extends outward from an outer surface of said distal section of the sleeve, wherein upon coupling of said first coupling element to said second coupling element, a relative position between said first coupling element and said second coupling element defines a position of a bend within said joint section, thereby the effective length (L p1; I p2) of the proximal section is adjustable by co-axially aligning proximal section with at least a portion of joint section such that the effective length (Ip) is alternated for the proximal section to conform to a length of the first body part of different subjects. a proximal section that is adapted to conform to the first body part; a distal section that is adapted to conform to the second body part; and a joint section between said proximal section and said distal section that is configured to conform with the anatomical joint, an effective Length (L p1; L p2) of proximal section is composed of length (L p) of the proximal section and a length (L hp1; L hp2) of a portion of the joint section coaxially aligned with proximal section, and extending from a proximal end to a bend of the joint section, and a releasable securing assembly comprising: a first coupling element and a second coupling element, wherein said first coupling element is configured for coupling to said second coupling element; characterized in that the first coupling element is coupled to and extends outward from an outer surface of said proximal section of the sleeve; and the second coupling element is coupled to and extends outward from an outer surface of said distal section of the sleeve, wherein upon coupling of said first coupling element to said second coupling element, a relative position between said first coupling element and said second coupling element defines a position of a bend within said joint section, thereby the effective length (L p1; I p2) of the proximal section is adjustable by co-axially aligning proximal section with at least a portion of joint section such that the effective length (Ip) is alternated for the proximal section to conform to a length of the first body part of different subjects. a first coupling element and a second coupling element, wherein said first coupling element is configured for coupling to said second coupling element; characterized in that the first coupling element is coupled to and extends outward from an outer surface of said proximal section of the sleeve; and the second coupling element is coupled to and extends outward from an outer surface of said distal section of the sleeve, wherein upon coupling of said first coupling element to said second coupling element, a relative position between said first coupling element and said second coupling element defines a position of a bend within said joint section, thereby the effective length (L p1; I p2) of the proximal section is adjustable by co-axially aligning proximal section with at least a portion of joint section such that the effective length (Ip) is alternated for the proximal section to conform to a length of the first body part of different subjects. the first coupling element is coupled to and extends outward from an outer surface of said proximal section of the sleeve; and the second coupling element is coupled to and extends outward from an outer surface of said distal section of the sleeve,
