The thuasne back support lombastab brace is used by people with medium to heavy physical work and pains in the lower back. the brace is suitable to use with acute low back pains or moderate to intense lumbar pain. the thuasne lombastab lumbar belt provides even compression and enhanced stability to ensure you remain supported throughout the day. fitting instructions: open the belt and lay it out completely flat. check that the two tightening handles are fully retracted. detach them from the velcro on the abdominal panel if necessary and pull on both ends of the belt. place the belt around your waist on top of a garment such as close-fitting vest. the lacing section must be centred over your spine. the pads should be positioned on either side of the spine. the bottom of the belt must stop at the top of the crease between the buttocks. fasten the belt using the wide velcro straps right side over left side without pulling too tight or applying any particular pressure. adjust the tightness using the two handles: pull them forwards then fold them flat against the front of the belt where they attach like velcro. you can use these two handles to adjust the level of compression as required throughout the day.
