4MinuteBack Physical Therapy Device sku-5911318184

The 4MinuteBack Unisex Physical Therapy back-stretch device (sku-5911318184; UPC 196852230006) fits over a door and adjusts in seconds. Softer arm pads and a built-in scale let the user set the amount of stretch while seated upright. Its metal bar separates for travel, and the device can be used at home, in an office or on the road.

The maker recommends following the directions and using it regularly for at least a week. It says the stretch helps relax tight back muscles, reduce pressure on the spine, maintain alignment between chiropractic adjustments, improve posture and rehydrate spinal discs. A doctor or physical therapist can recommend a force setting for individual needs.

The maker says doctors, chiropractors and physical therapists use the device in offices and patients' homes, and offers email support for questions.
