SPORTS MEDICINE SOLUTIONSHamstrings
System 4 Supports Hamstring Protocols
Hamstring injury is serious business. Regardless of whether you have an existing process
for protecting and strengthening hamstrings, the objective test protocols offered with the
Biodex System 4 will provide valuable, isolated muscle-performance data. Test results, combined with established targeted outcomes, can be used for pre-emptive injury screening, managing rehabilitation and determining readiness for return-to-play.
Upgrade path available for existing System 4 and System 3 dynamometers.
Multiple Angle Comparison Test
Examines isometric bilateral flexion peak
torque symmetry where the limb position
puts the hamstring in a lengthened
(stretched) state. Passive stretch is the
inherent force (or torque) produced by
the hamstring in the lengthened state.
When deficits are within 10%,
predisposition to reinjury is significantly
reduced.
NOTE: This Protocol requires 830-550 Hamstring Attachment. Use of any attachment other than the 830-550, is outside proper and intended use.

Mixed H/Q Ratio Test
Uses a ratio of eccentric and concentric flexion peak torque where, if the ratio exceeds 1.4, hamstring injury is greatly diminished.
NOTE: This Protocol utilizes standard Biodex Knee Attachment.
Available with Advantage Software v4.63. Coming soon to Advantage BX™.
