Introduction
Knee´s biomechanical assessment in patients with knee pain
without good clinical-radiological diagnostic, provide us
good functional information and allows us to objectify the
physiotherapy treatment.
The study purpose is to register the improvement after the
individualized physiotherapy treatment according the
biomechanical assessment.
Materials and methods One male patient, 27 years, police. Knee unspecific pain.
Sick leave for 12 month. No abnormalities on NMR. The
patient does not improve with physiotherapy and
pharmaceutical treatment
Biomechanical assessment before and after physiotherapy
treatment with EMG for the muscle activity, dynamometric
stage and implemented templates for the human gait
analysis and isokinetic system for the muscle strength
The patient makes individualized physiotherapy treatment
once a week with PT by analytical strengthening and
specific stretching of the affected muscles and manual
therapy
The patient makes every day specific exercises ruled by
physiotherapist as objectified deficits in the biomechanical
assessment
Results Before the treatment the patient has an irregularity human
gait, with deficit at the heel crash and overpressure at
footprint. The patient presents deficit and imbalance in the
hamstring and he has knee muscle imbalance in agonist /
antagonist that improves with physiotherapy treatment
Figure 1. EMG before and after treatment
After the treatment the patient has an irregularity human
gait with normal heel crash. Hamstring balance is normal.
Figure 2. Human gait analyzed by dynamometric stage
before and after treatment
Figure 3. Human gait analyzed by implemented templates
before and after treatment
Conclusion
Knee stability is fundamental at the correct human gait
Biomechanical assessment promotes early and effective
treatment of injuries, preventing the onset of chronicity and
functional deficiencies
Biomechanical studies support individualized
physiotherapy, accelerating the return to work and reduce
healthcare costs
