Many people's reflex when facing sciatica: stop moving. This is the most common mistake. Total rest slows down nerve recovery and maintains the muscle contractures that compress the nerve.
What you need: gentle, targeted mobility, practiced regularly. Here are the 5 most effective exercises used in physical therapy clinics.
If any of these exercises aggravates the pain in your leg, stop immediately. In the intense acute phase (first 72 hours), limit yourself to exercises 1 and 2 only.
Exercise 1 — The piriformis stretch
The most important one. Do this first.
Position: lying on your back. Cross the ankle of the painful leg over the opposite knee. Grasp the back of the opposite thigh and pull gently toward your chest.
Sensation: a deep stretch in the buttock.
Duration: 30 to 45 seconds · 3 repetitions · 2 times a day.
Why it works: directly targets the piriformis muscle — the main cause of "false sciatica" and an aggravating factor for disc-related sciatica. It is the #1 exercise recommended by physical therapists for sciatica.
Exercise 2 — Knee-to-chest
Position: lying on your back. Pull one knee toward your chest; the other leg remains flat on the floor.
Duration: 30 seconds · 3 repetitions on each side.
Why it works: stretches the lower back and creates space around the compressed nerve root. Can be done from the very first hours of a flare-up.
Exercise 3 — Lumbar extension (sphinx)
Position: lying on your stomach. Supporting yourself on your elbows, gently lift your torso. Keep your hips on the floor.
Duration: 30 to 45 seconds · 3 repetitions.
Why it works: reduces pressure on the posterior part of the disc (herniated disc). Positive signal: if the pain in your leg decreases during the exercise, continue. If it increases, stop.
Exercise 4 — Cat-cow mobilization
Position: on all fours, hands under shoulders. Inhale while slightly arching your back (cow). Exhale while rounding it as much as possible (cat). Move slowly and fluidly.
Duration: 10 repetitions · 2 sets.
Why it works: mobilizes the lumbar spine and relieves accumulated tension. Ideal in the morning upon waking before getting up.
Exercise 5 — Sciatic nerve neuromobilization
Position: sitting on the edge of a chair, back straight. Extend the painful leg horizontally (foot flat), hold for 5 seconds, then return the foot under the chair.
Duration: 10 slow repetitions · 1 set.
Why it works: "flosses" the sciatic nerve in its track and gradually releases adhesions. Introduce in the sub-acute phase (from day 3-5), not during an intense acute crisis.
How to combine exercises and therapy
Exercises release mechanical tension. To maximize their effect:
- Before exercises — 10 minutes of 660 nm red light prepares the nerve and muscle tissues, reducing inflammation before stretching
- After exercises — 45–65°C heat maintains the relaxation achieved and prevents muscle soreness
- Frequency — 2 times a day in the acute phase (exercises 1 and 2 only) · 1 time a day for maintenance (all 5 exercises)
🔷 Maximize the effect of your exercises
✦ 660 nm red light before — prepares tissues, reduces inflammation before stretching
✦ 45°C–65°C heat after — maintains the relaxation achieved during the exercises
✦ 2 x 6,000 RPM motors — releases deep contractures that stretching alone cannot relieve

How many times a day should I do these exercises?
2 times a day in the acute phase (exercises 1 and 2 only). 1 time a day in the chronic phase (all 5 exercises). Daily consistency is more important than intensity.
Do these exercises replace physical therapy?
No. They maximize effects between sessions. The physical therapist tailors the program to your specific case and uses manual techniques that no home exercise can replicate.
Can I do these exercises at the office?
Exercise 1 (seated piriformis stretch) and exercise 5 (seated neuromobilization) can be done discreetly at the office. The others require the floor.
How long before I see results?
Partial relief can be felt from the very first sessions. Significant improvement generally appears after 1 to 2 weeks of regular daily practice.
