Objective:To investigate the Effect of Pine muscle nursing training and external application of loose tendon ointment on muscle strength and muscle tension in patients with disused knee joint contracture.Method:From August 2018 to June 2019, 80 subjects were selected in the hospital, divided into three groups using the random number table method, and arranged in different wards. The routine rehabilitation group performs routine hospital rehabilitation (good limb placement, massage, active and passive exercise training), routine rehabilitation + pine muscle nursing training group is to implement rehabilitation nursing training on the basis of conventional rehabilitation treatment in hospital (relaxation training, hand micro-vibration therapy, pasteurization training), routine rehabilitation + pine muscle nursing training + medication group is based on the conventional rehabilitation treatment and pine muscle nursing training of hospitals to implement external application of loose tendon ointment. After 8 weeks of intervention, the muscle strength of the affected quadriceps (knee extensor) and the biceps femoris (Knee flexor) were compared.Results:Before the intervention, the patients in the three groups all experienced a decrease in the strength of the affected quadriceps muscle, and the flexion contracture of the knee joint caused by the hypertonic biceps muscle tension (minimum value ≥5uV) ( P>0.05). After 8 weeks of intervention, the muscular tone of the affected biceps femoris in the three groups was decreased ( F=10.623, P<0.001), and the muscle strength of the quadriceps femoris was increased ( F=10.888, P<0.001).The pairwise comparison results showed that compared with the conventional rehabilitation group, the difference between the conventional rehabilitation + pine muscle nursing training group was significant ( P<0.05), and the difference between the conventional rehabilitation + pine muscle nursing training + medication group was significant ( P<0.001). Compared with the routine rehabilitation + pine muscle training group, the difference between the conventional rehabilitation group and the routine rehabilitation + pine muscle nursing training + medication group was significant (both P<0.05). Conclusion:Patients with disused knee flexion contracture treated with Pine muscle nursing training combined with external application of loose tendon ointment can loosen the contraction and stiffness of the joint tissue, significantly reduce the muscle tension of the flexor knee muscle, increase the strength of the extensor knee muscle, restore and improve The rhythmic contraction and relaxation ability of the flexion and extension knee muscles makes their muscle strength/muscle tension ratio tend to balance, enhance the coordination control ability between muscle groups, and effectively reduce the degree of knee flexion contracture.
