About this trial

The goal of this clinical trial is to assess the effectiveness of isokinetic rehabilitation training under optimal stiffness in patients undergoing knee joint rehabilitation. The main questions it aims to answer are:

* Does isokinetic training under optimal stiffness lead to greater force exertion compared to traditional bodyweight training? * What are the long-term (6-week) effects of isokinetic training under optimal stiffness on joint flexibility and muscle strength? Researchers will compare the effects of isokinetic training under optimal stiffness to traditional bodyweight training to see if isokinetic training produces superior improvements in muscle strength, flexibility, and overall functional recovery.

Participants will:

* Perform regular training sessions using a portable knee joint isokinetic trainer, customized to their optimal stiffness for maximum force exertion. * Engage in a 6-week rehabilitation program, with assessments at the beginning, and end of the study to evaluate changes in muscle strength, and functional recovery.

Trial outcomes

Primary outcomes

1

Cross-sectional area of the quadriceps

Using MRI,Up to 6 weeks

Time frame
Before 1st practice, and after 12th practice (6 weeks * 2 practices/week = 12 practices)
2

Cross-sectional area of the hamstrings

using MRI, Up to 6 weeks

Time frame
Before 1st practice, and after 12th practice (6 weeks * 2 practices/week = 12 practices)
3

Peak flexion and extension knee torque

Using an integrated torque sensor

Time frame
During each practice (6 weeks * 2 practices/week = 12 practices).
4

Average flexion and extension knee torque

Time frame
During each practice (6 weeks * 2 practices/week = 12 practices).

Secondary outcomes

1

Thigh circumference

10 cm proximal to the superior pole of the patella

Time frame
In each ptractice (6 weeks * 2 practices /week = 12 practices).
2

Knee joint pain score (VAS score)

Up to 6 weeks,max. =100, min. =0, Visual Analogue Scale=VSA, A higher score indicates greater pain intensity.

Time frame
Before 1st practice, and after 12th practice (6 weeks * 2 practices/week = 12 practices)
3

Surface electromyography signals of quadricep and hamstrings

SEMG signals are used to evaluate the instant effect brought by the optimal stiffness.

Time frame
During optimal stiffness measurements
