HAMSTRINGS

Hamstring injury is a problem that permeates through all levels of sports,Mediquipe social media graphics 6 from professional to amateur to recreational – and the rate of re-injury is high. Mounting evidence suggests the risk of re-injury can be minimised by using rehab strategies that incorporate neuromuscular control exercises and eccentric strength training, combined with objective measures to assess readiness to return to sport.

High incidence rate, slow healing, persistent symptoms, and a historically high rate of recurrence have made hamstring injuries a challenge for both athletes and the clinical team responsible for their recovery. 

System 4 Supports Hamstring Protocols

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 returning to play.

NEW Return-to-Play Reports

Biodex introduces the first Return-to-Play report for hamstring injury, now available with System 4 Advantage BX™ software:

  • Shows clear pass/fail test results
  • Grounded in the latest research
  • Simplifies communication with athletes, physicians and third-party payers
  • Supports two commonly used hamstring rehab protocols: 
    • Lengthened State - Multiple Angle Comparison
    • Mixed H/Q Ratio

Upgrade path available for existing System 4 and System 3 (rev. 2) dynamometers.

Protocol #1:

Lengthened State - Multiple Angle Comparison Test

Hamsting lengthened report example

Examines isometric bilateral flexion peak torque symmetry where the limb

NOTE: This Protocol requires 830-550 Hamstring Attachment. Use of any attachment other than the 830-550, is outside proper and intended use 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.

Protocol #2:

Mixed H/Q Ratio Test

Mixed Ratio Hamstring return-to-play report

Uses a ratio of eccentric and concentric flexion peak torque where, if the ratio exceeds 1.4, hamstring injury is greatly diminished.
Now available with Advantage BX™ 5.3.

NOTE: This Protocol utilises the standard Biodex Knee Attachment.
