Gaitsymmetryassessment method used after anterior cruciate ligament reconstruction

Abstract

The invention relates to a gait symmetryassessment method used after anterior cruciate ligament reconstruction. The gait symmetryassessment method is characterized by comprising the following steps that 1, plantar pressure data of a sampled individual is acquired, and parsing processing is conducted on the acquired plantar pressure data to obtain symmetry results of plantar pressures on two sidesof the sampled individual under different load-decreasing amplitudes; 2, according to the symmetry results of the plantar pressures on the two sides of the sampled individual under different load-decreasing amplitudes, initial load-decreasing amplitude for load-decreasing running training is determined, and according to assessment results of plantar stress symmetry of the sampled individual in therunning process under the initial load-decreasing amplitude, the load-decreasing amplitude for load-decreasing running training is adjusted until balanced load bearing of the lower limbs on the two sides of the sampled individual under non-weigh-losing condition is achieved. The gait symmetryassessment method can be widely applied to the field of gait symmetryassessment method used after anteriorcruciate ligament reconstruction.

Description

technical field [0001] The invention relates to the field of gait research, in particular to a gait symmetry evaluation method after anterior cruciate ligament (Anterior Cruciate Ligament, ACL) reconstruction based on plantar pressure information. Background technique [0002] At present, the incidence of sports injuries is gradually increasing, and knee anterior cruciate ligament injury is one of the most common sports injuries. In the United States, the incidence of ACL injury is about 1 in 3000, and the cost of surgery alone is as high as one billion dollars per year. Among professional athletes with ACL injury in my country, the incidence rate of the injury is 0.71% for women and 0.29% for men. ACL injury seriously affects human sports ability, and after ACL injury cannot heal naturally, arthroscopic reconstruction of ACL has become the first choice in clinical practice. [0003] However, the prognosis after ACL reconstruction is not satisfactory. Studies have reported...

Problems solved by technology

[0004] Improving the force asymmetry after ACL reconstruction is a prerequisite for improving the rehabilitation effect after ACL reconstruction and preventing postoperative reinjury. Although there are a large number of studies on the gait symmetry after ACL reconstruction, there is no solution yet. The symmetry of the force on the lower limbs of patients after ACL reconstruction, there are still a large number of studies reporting the characteristics of movement asymmetry after ACL reconstruction
