Horse riding can work as a corrective measure for knock knees.

Knock knees, also known as genu valgum, is a condition where the knees touch each other while the ankles are apart. This leads to an inward angling of the lower legs, creating an appearance of the knees "knocking" together. It can be caused by various factors such as genetics, obesity, or certain medical conditions.

Horse riding can be beneficial for correcting knock knees due to the following reasons:

1. Strengthening of leg muscles: Horse riding requires the rider to maintain a proper posture and balance while riding. The rider's legs are constantly engaged to maintain stability and control. This helps in strengthening the muscles of the legs, including the quadriceps, hamstrings, and calf muscles. Stronger leg muscles can help in realigning the knees and correcting knock knees.

2. Improvement in posture: Horse riding requires a correct posture, with the rider sitting tall and straight. This helps in aligning the spine and pelvis properly. As knock knees can be associated with poor posture and misalignment of the lower body, horse riding can help in improving overall posture and alignment, which can indirectly correct knock knees.

3. Development of core stability: Horse riding also requires the rider to engage their core muscles to maintain balance and stability. The core muscles include the abdominal muscles, back muscles, and pelvic floor muscles. Developing core stability can contribute to better overall body alignment, including the alignment of the lower limbs, and can aid in correcting knock knees.

4. Stretching of hip adductor muscles: The riding position in horse riding involves the rider's legs being positioned apart, which helps in stretching the hip adductor muscles. The hip adductor muscles are located on the inner side of the thighs and can contribute to knock knees if they are tight or shortened. Stretching these muscles through horse riding can help in correcting the alignment of the knees.

It is important to note that horse riding should be done under proper supervision and guidance, especially when used as a corrective measure for knock knees. It is recommended to consult with a healthcare professional or an experienced riding instructor to ensure safety and effectiveness.
