Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Peak Functional Lower-Limb Force | Baseline and post-intervention (Week 8). | Peak lower-limb force will be assessed using an electromechanical dynamometer (DynaSystem) during an instrumented sit-to-stand-to-sit task performed under isokinetic (15 cm/s) and isotonic (60% of body weight) conditions. Peak force will be normalized to body mass and expressed in N/kg. Changes from baseline to post-intervention will be compared between groups. |
| Primary | Peak Functional Lower-Limb Power | Baseline and post-intervention (Week 8). | Peak lower-limb power will be assessed using an electromechanical dynamometer (DynaSystem) during an instrumented sit-to-stand-to-sit task performed under isokinetic (15 cm/s) and isotonic (60% of body weight) conditions. Peak power will be normalized to body mass and expressed in W/kg. Changes from baseline to post-intervention will be compared between groups. |
| Secondary | Muscle Oscillation Frequency | Baseline and Week 8 (post-intervention) | Muscle oscillation frequency will be assessed using a handheld myotonometer (MyotonPRO) in the vastus medialis, vastus lateralis, and medial gastrocnemius muscles. Oscillation frequency, expressed in hertz (Hz), will be used as an indicator of muscle tone. Changes from baseline to post-intervention will be analyzed for each muscle. |
| Secondary | Musculotendinous Stiffness | Baseline and Week 8 (post-intervention) | Musculotendinous stiffness will be assessed using a handheld myotonometer (MyotonPRO) in the vastus medialis, vastus lateralis, and medial gastrocnemius muscles, as well as the patellar and Achilles tendons. Stiffness will be expressed in newtons per meter (N/m). Changes from baseline to post-intervention will be analyzed separately for each anatomical structure. |
| Secondary | Muscle Logarithmic Decrement | Baseline and Week 8 (post-intervention) | Muscle logarithmic decrement will be assessed using a handheld myotonometer (MyotonPRO) in the vastus medialis, vastus lateralis, and medial gastrocnemius muscles. This dimensionless parameter describes the damping of natural tissue oscillations and is used as an indicator of muscle elasticity. Changes from baseline to post-intervention will be analyzed for each muscle. |
| Secondary | Muscle Relaxation Time | Baseline and Week 8 (post-intervention) | Muscle relaxation time will be assessed using a handheld myotonometer (MyotonPRO) in the vastus medialis, vastus lateralis, and medial gastrocnemius muscles. Relaxation time will be expressed in milliseconds (ms) and represents the time required for the tissue to recover its shape following mechanical deformation. Changes from baseline to post-intervention will be analyzed for each muscle. |
