Short-term effects of limb rehabilitation robot combined with proprioceptive training on functional recovery following military training-related anterior cruciate ligament reconstruction
Objective To explore the clinical effect of limb rehabilitation robot combined with propriocep-tive training in knee arthroscopic anterior cruciate ligament ( ACL) reconstruction.Methods A retrospective analy-sis was conducted on 87 cases of knee ACL injuries following military training,who were treated at the General Hos-pital of Northern Theater Command by arthroscopic ACL reconstruction.There were 83 males and 4 females aged 19-41 (mean 30.2) years.Patients were divided into two groups according to the postoperative rehabilitation plans:patients in the observation group received limb rehabilitation robot-assisted training combined with proprioceptive training(n=43) while those in the control group received only conventional rehabilitation(n=44).The rehabilita-tion training time was set as 8 weeks for all patients.The IKDC score,Lysholm score,VAS,and dynamic gait analy-sis data by Gait-watch were recorded at2,4 and8 weeks after surgery.Results Patients were followed up for9-54 (mean 33.6) weeks.At the three observational time points,VAS revealed no significant difference (P>0.05 for all time points),Gait-watch showed much better dynamic gait data in the observation group than in the control group at postoperative 4 weeks (step length:cm,67.7±7.8 vs.64.4±7.1;step frequency:steps/min,89.0±9.2 vs.85.5±7.4;step speed:cm/s,83.2±5.9 vs.77.8±6.5) and 8 weeks (step length:cm,75.5±5.8 vs.67.4±7.6;step frequency:steps/min,103.3±7.6 vs.89.1±9.4;step speed:cm/s,98.2±10.3 vs.89.2±8.2,all P<0.05),while the IKDC score and Lysholm score only showed significantly better results at postoperative 8 weeks in the observation group than in the control group (IKDC score 7.0±0.8 vs.6.4±0.9;Lysholm score 74.6±5.5 vs.69.1±6.1,both P<0.05).Conclusion Lower limb rehabilitation robot combined with proprioceptive train-ing is beneficial for the early recovery of knee function after ACL reconstruction.
