Effect of Dynamic Four-point Kneeling Training on Hip Bone Mineral Density and Lower Extremity Motor Function in Patients with Spinal Cord Injury
Objective:To investigate the effects of dynamic four-point kneeling training on hip bone mineral density and lower extremity motor function in patients with spinal cord injury.Methods:A prospective randomized controlled study was applied to select 80 patients with spinal cord injury from January 2019 to January 2022,and they were divided into the control group(40 cases)and the observation group(40 cases).The control group received routine rehabilitation training and upright bed training,and the observation group received routine rehabilitation training and dynamic four-point kneeling training.Both groups received continuous intervention for 12 weeks.Hip bone mineral density,EMG,sensory score,lower extremity motor function score(LEMS),muscle tension of quadriceps,gluteus maximus and hamstring(modified ashworth scale)and muscle strength of the two groups before intervention,and at the 4th,8th and 12th weeks after intervention were compared.The incidence of adverse events(postural hypotension,knee pain,friction injury and fall)in the two groups were also analyzed.Results:After 4,8 and 12 weeks of intervention,the T-value of both groups was lower than that before intervention,and the mean value of the observation group was higher than that of the control group(P＜0.05).After 4,8 and 12 weeks of intervention,the surface electromyography integral value and LEMS of both groups were higher than those before intervention,and the observation group was higher than the control group(P＜0.05).Before intervention,and at the 4th,8th and 12th weeks of intervention,the muscle tension of the observation group was lower than that of the control group(P＜0.05);There was no significant difference in sensory scores between the two groups(P＞0.05).At the 4th,8th and 12th weeks of intervention,the muscle strength of the observation group was higher than that of the control group(P＜0.05).There was no significant difference in adverse events between the two groups(P＞0.05).Conclusions:Dynamic four-point kneeling training can stimulate the contraction of the muscles around the hip joint under partial weight,delay the loss of hip bone mineral density in patients with spinal cord injury,improve the lower extremity motor function below the injury plane,and the treatment risk is low.
