KS106 Leg Press Trainer —Bilateral Hydraulic Functional Leg Press Rehabilitation

The AE-KS106 Leg Press Trainer is a clinical-grade bilateral hydraulic leg press rehabilitation machine — simultaneously engaging the quadriceps, gluteus maximus, gluteus medius, hamstrings, gastrocnemius, and soleus in the compound pushing movement pattern that underpins virtually every lower limb functional activity in daily life.

The two-way hydraulic resistance — starting from the lowest possible resistance limit with low inertia — delivers the safe, precise, progressively dosed multi-joint lower limb loading needed across the full spectrum of rehabilitation populations: from the earliest post-hip arthroplasty patients beginning bilateral push under surgical precautions, through the sub-acute stroke patient developing voluntary lower limb force, to the elderly patient rebuilding the functional leg strength essential for safe independent living.

Key Features —

Two-Way Hydraulic Resistance — Safe Multi-Joint Loading from Lowest Limit The hydraulic resistance mechanism's low-inertia, lowest-limit starting capability is particularly important for the leg press because the KS106 loads three joints simultaneously — the hip, knee, and ankle. In post-hip or post-knee arthroplasty patients, post-fracture patients, and elderly patients with osteoporosis, any sudden inertial force spike at multi-joint loading initiation carries compounded risk across all three joints. The hydraulic mechanism's smooth-start resistance eliminates this risk, enabling safe multi-joint loading from the earliest rehabilitation stage.

Two-way resistance provides:

1. Push phase (extension) resistance: Quadriceps, gluteus maximus, gluteus medius, and gastrocnemius/soleus all loaded concentrically during the bilateral leg push — the primary strengthening stimulus
2. Return phase (flexion) resistance: Hip flexors, knee flexors (hamstrings), and dorsiflexors loaded concentrically during the return — training the eccentric control and flexor strength needed for safe sit-to-stand lowering, stair descent, and controlled gait deceleration

• Bilateral Simultaneous Multi-Joint Integration The KS106 trains both legs simultaneously in a coordinated bilateral push-and-return cycle — the most functional training pattern for lower limb rehabilitation because virtually all the critical functional activities it targets (sit-to-stand, standing, walking push-off) involve bilateral simultaneous lower limb loading. Bilateral training also ensures that left-right strength symmetry develops alongside overall strength — critical for gait symmetry and fall prevention.
• Ergonomic Joint Alignment — Hip, Knee, and Ankle The KS106's foot platform angle, seat position, and joint contact surfaces are designed to simultaneously optimise force vector alignment at the hip, knee, and ankle — the three joints loaded in every repetition. This three-joint ergonomic alignment minimises shear stress at the tibiofemoral and patellofemoral joint surfaces, maintains safe hip joint loading angles within common arthroplasty precautions, and ensures ankle plantarflexion occurs through a biomechanically optimal arc — protecting all three joints during multi-joint loading.
• Lowest Resistance Limit — Bridging from KS105 Isolation to Functional Integration The ability to begin leg press training at the lowest possible resistance limit ensures that the transition from isolated KS105 knee training to integrated KS106 multi-joint training can be made without a step-change in absolute load that would exceed the patient's current capacity. The physiotherapist can introduce KS106 multi-joint training at minimal resistance while the patient's isolated knee and hip strength (developed on KS104 and KS105) continues to build — gradually increasing KS106 resistance as functional integration strength develops.
