Abstract: A wearable bio-engineered device for preventing cervical spine and other musculoskeletal injuries in humans. The device includes a support frame having a pair of spaced apart support arm members that gently engage about the sides of the human neck of the wearer; and a chin support member supported by said support frame and disposed beneath the chin and above the chest of the wearer. The support frame and chin support member are configured and sized so that when the head of the human wearer flexes downward towards the chest of the wearer, while viewing the handheld mobile device, the chin support member is positioned directly between the chin and chest of the wearer and physically constrains and limits the neck from flexing and head from tilting beyond a predetermined flexion limit set by the physical length dimensions of the spaced apart support arm members and the physical height dimension of the chin support member.
