Wearable Vibration Effect on Biomechanics and Biomarkers After ACL Reconstruction

The Effects of a Wearable Vibratory Device on Biomechanics, Quality of Life and Serum Biomarkers After an ACL Reconstruction Surgery

Anterior cruciate ligament (ACL) injuries account for up to 25% of knee injuries, it is estimated that 32,000-400,000 new cases of ACL tears occur in the USA every year.

The Standard care is twofold; a) ACL reconstruction surgery and b) prolonged rehabilitation period (usually no less than 9 months). However, a large amount of patients do not return to their pre-injury activity level, and up to 30% reinjure their ACL in the following two years.

The wearable system consists of two non-invasive bands, above and below the knee that vibrate during the weight bearing phase while walking.

The objective of this study is to investigate the effect of treatment for ACL reconstruction, including vibrational stimulation and pressure, on locomotion tasks (i.e. walking, stair ascending and descending), muscle function, and pain/function.

Inclusion Criteria:

• Provision of signed and dated informed consent form
• Males and females
• Aged 18-50
• Scheduled for an ACL reconstruction in Rambam hospital.
• Hebrew language at mother tongue level

Exclusion Criteria:

• Inability to understand the study protocol.
• Known neuropathies, active cancer, previous fractures in the lower limbs, inflammatory arthritis, implanted electronic devices of any kind.
• Allergies to silver or adhesives.
