A 45 degree back extension bench (note the different type of leg support from the Roman chair) Using a reverse back extension machine (reverse hyperextension machine) This machine has been used to strengthen not only the erector spinae muscle, but also gluteus maximus and part of hamstring muscles (biceps femoris).
However, the 90-degree machine, because of its steeper angle, presents a higher level of difficulty and allows for a broader range of exercises like glute ham raises and reverse hyperextensions.
Another option for doing a raise to target the posterior deltoid is hyperextending the glenohumeral joint. The lat is no longer an extensor at this point, so it is primarily the posterior deltoid and long head of the triceps that perform hyperextension. The range of motion for this is very limited, most people can't even hyperextend 45 degrees.
The brace uses what the inventor calls Alternative Load Path Technology to help absorb and disperse injury-producing forces. [4] The brace is designed to limit hyperflexion, hyperextension, lateral hyperflexion and posterior hypertranslation, which are extreme forward, backward, sideways, and rearward movement of the head on the neck.

Individuals with Modic changes experience exacerbation of pain when performing a hyperextension of the back. [ 15 ] [ 16 ] A hyperextension of the back is the equivalent of performing an excessive backward bending of the back beyond its natural position.
The spill involved heavy M100-grade fuel oil that solidifies at a temperature of 25 degrees Celsius (77 degrees Fahrenheit) and, unlike other oil products, does not float to the surface but sinks ...
Variations in the angle are denoted by high Fowler, indicating an upright position at approximately 90 degrees and semi-Fowler, 30 to 45 degrees; and low Fowler, where the head is slightly elevated." [ 1 ] It is an intervention used to promote oxygenation via maximum chest expansion and is implemented during events of respiratory distress.
