Figure 1: The Biodex Multi-Joint System 3 with Dual Position Back Ex/Flex
Attachment. The patient is exercising in the semi-standing (functional) posi-
tion. For exercise or testing in the seated-compressed position, remove the lum-
bar pad, raise the seat to the inclined position, and insert both the sacral pad
and lower extremity compression device.
The Dual Position Back Ex/Flex Attachment was created to provide clini-
cians with greater versatility in back testing and rehabilitation. With this
system, patients can perform both semi-standing and seated-compressed
lumbar back extension/flexion. This allows the clinician to objectively
measure muscle performance in both functional and isolated capacities.
The attachment is easily connected or disconnected from the dynamome-
ter and conveniently rolled aside for storage when not in use.
