Lower-limb rehabilitation supports recovery of movement and function in the legs after injury, surgery or other conditions. A plan can be adapted to walking, stairs and the tasks that matter to you.
For an individual assessment, see our sports injury rehab assessment and care.
Common Lower Limb Injuries We Rehab (Causes & Symptoms)
Phase 1: Protection and Gentle Mobility (Weeks 1-4)
- Heel Slides: Lying down, gently slide your heel towards your buttock, flexing the knee only as far as comfortable. This is excellent for maintaining knee flexibility.
- Static Quad Sets: Contract your thigh muscle, pushing the back of your knee down into the bed or floor. Hold for 10 seconds. This is foundational for preventing quad weakness.
- Ankle Pumps: Moving your foot up and down to encourage circulation and reduce swelling.
This phase is slow by design. Patience is your most important exercise.
Phase 2: Strength and Stability (Progression Based on Function)
Once you have achieved good, pain-free mobility, you move into the strengthening stage. This phase introduces progressive load — meaning you will start challenging the muscles surrounding the injured joint. This is where functional strength — the kind you use in daily life — is built. We focus heavily on balance, as proprioception (your body's awareness of its position in space) is severely affected by injury.
Key Strength Builders:
- Mini-Squats and Wall Slides: These controlled exercises strengthen the quads and glutes without excessive shear force on the knee. Focus on keeping your knees tracking over your feet.
- Standing Calf Raises: Essential for ankle and lower leg stability. Progress from two legs to one leg as strength allows.
- Glute Bridges: Excellent for hamstring and glute activation, crucial for supporting the lower back and pelvis, which in turn support the legs.
- Single-Leg Stance: Start with eyes open, holding onto a wall; progress to eyes closed, free-standing. This significantly improves balance and coordination.
You may also introduce light resistance bands here. Resistance band walking (sideways, forward, backward) is fantastic for hip abductor strength, a hidden powerhouse for knee and ankle health.
Phase 3: Functional Training and Return to Sport (Weeks 12+)
This final phase is the bridge back to your normal activities, whether that means running a marathon or simply playing with your kids. It involves high-level balance, agility, and power work. You should only start this phase when your strength symmetry is near 90% compared to your uninjured side.
Advanced Functional Movements:
- Plyometrics: Low-box jumps, hopping drills, and lateral bounds. These train your muscles to absorb and generate force quickly.
- Sport-Specific Drills: If you are returning to football, this might include cutting, pivoting, and rapid change-of-direction drills.
- Endurance Work: Gradual reintroduction of running, cycling, or swimming, carefully monitored for pain response.
A successful rehabilitation program is comprehensive, structured, and overseen by a professional. By following these three phases and prioritising consistency, you can not only recover, but emerge stronger than before.
When to See a Physiotherapist
Book an assessment as soon as possible after any significant lower limb injury, rather than waiting to see if it settles on its own — early, guided Phase 1 work meaningfully reduces the risk of the stiffness and weakness that make later phases harder. It's equally worth an assessment if you're already weeks or months into recovery but still feel unstable, weak, or not quite back to normal, since that's usually a sign a phase was rushed or skipped rather than something that will simply resolve with time.
Preventing Re-Injury
- Don't return to sport or heavy activity based on how much time has passed — base it on actual strength and symmetry testing
- Keep up hip and ankle strength work even after "finishing" rehab, since these are the areas most likely to quietly weaken again
- Warm up properly before sport, including some of the balance and plyometric drills from Phase 3
- Don't skip Phase 2 strength work in favour of jumping straight to sport-specific drills — it's the foundation everything else in Phase 3 depends on
Lower Limb Rehabilitation Near Apollo Hospital, Sarita Vihar
Symphysio Physiotherapy Clinic, Sarita Vihar, guides patients through structured, phase-based lower limb rehabilitation from across Jasola, Okhla, Sukhdev Vihar, New Friends Colony, Kalindi Kunj, Badarpur, and the wider Apollo Hospital area of South Delhi — whether recovering from a simple sprain or a post-surgical ACL reconstruction.
If your rehab follows a recent surgery rather than an injury alone, our guide to post-surgery physiotherapy in Sarita Vihar walks through recovery timelines by procedure type in more detail.

Frequently Asked Questions
It varies by injury — a simple ankle sprain may move through all three phases in 6-8 weeks, while an ACL reconstruction typically takes 6-9 months to fully complete Phase 3 and return to sport safely.
It's not recommended. Phase 1's mobility and swelling control lay the groundwork for effective strengthening in Phase 2 — skipping it often means strength work gets built on a joint that isn't moving properly yet.
Progression should be based on specific markers — pain-free range of motion before Phase 2, and roughly 90% strength symmetry with the uninjured side before Phase 3 — rather than a fixed calendar date. Your physiotherapist tracks this at each session.
It's common but not something to just live with — persistent instability usually means balance and proprioception work wasn't fully completed, and it's very treatable with a targeted Phase 2/3 programme even months later.
No — this three-phase approach applies whether your injury is being managed conservatively (like most ankle sprains and many meniscus tears) or post-surgically (like an ACL reconstruction). The pacing and specific exercises are adjusted to your situation.
