Abstract:

A telescoping arm comprises a distal end and a proximal end. A head portion is adapted to contact a human back, and is configured to connect to the distal end of the arm. A base is configured to connect to the proximal end of the arm. The base comprises a first drive and a second drive. In one embodiment, the first drive is configured to move the arm in an alternating lateral motion. In another embodiment, the first drive is configured to move the arm in an alternating pivoting motion. The second drive is configured to alternately extend and retract the arm. A single motor may be coupled to both of the first and second drives, or each drive may include a separate motor. The first and second drives are configured to operate simultaneously. A clip is attachable to the base, for removably attaching the base to a stable object. An inverted cradle shaped base extension is also attachable to the base, for resting the back scratcher on a sofa arm.
