Motor Performance Modulation After Total Knee Replacement

Status Completed

Clinical Trial Summary

Functional recovery after total knee replacement (TKR) is characterized by an incomplete muscle strength due to arthrogenic muscle inhibition (AMI) and tendency to estimate the functional level. These deficits could be related to alteration of sensory feedback, and could influence the ability to modulate patients' motor performance. To date, there are not studies investigatin the ability to modulate the motor performance in patients with TKR compared to healthy age-matched subjects. In this study 20 patients with TKR and 20 healthy will be included . Inclusion criteria are: age between 40 and 80 , TKR for primary knee osteoarthritis, knee flexion ≥ 90° and complete knee extension, ability to perform a sit to stand on a 46 cm high chair and to walk for at least 50 meters without aids. Exclusion criteria: patients undergoing TKR after traumas, previous tibial or femoral osteotomy, partial or complete revision surgery. subjects with psychiatric and/or cognitive impairments, or with neurological, musculoskeletal or other disorders that could influence motor or functional recovery will be also exluded. The aim of the study is to investigate the ability in motor performance modulation in patients after TKR compared to healthy age-mtched subjects. Primary endpoint is to investigate this ability during a leg extension performed in open kinetic chain. This ability will be also evaluated during a Sit To Stand and during walking (with 10 Meters Walking Test). Secondary endpoint is to investigate pain, rate of perceived exertion and perceived load symmetry during the three tests. In both healthy and TKR groups these outcomes will be detected two times. In particular, in TKR group, patients will be tested the day before surgery and 5 days after surgery. This study is aimed at conducting a survey in healthy subjects and in a population of subjects undergoing TKR . Participants will undergo an acquisition similar to others already described in the literature and without adverse events. Tests will last about 60 minutes and during them, will be used the equipment of Motion Analysis Lab of "Humanitas Research Hospital".

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
