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
