Here is a clear, useful guide on trunk muscle spasm and the best exercises to relieve and strengthen the trunk.
⸻
✅ What is Trunk Muscle Spasm?
A trunk muscle spasm is a sudden, involuntary tightening of muscles in the:
• Lower back
• Mid back
• Abdomen
• Side trunk (obliques)
It usually happens due to:
• Poor posture
• Sudden twisting -lifting
• Weak core muscles
• Overuse
• Neurological conditions (CP, stroke, spinal issues)
• Muscle fatigue -dehydration
⸻
✅ Immediate Relief for Spasm
1. Heat Therapy (10–15 mins)
• Hot pack on the affected area
• Relaxes tight muscles and reduces pain
2. Gentle Stretching
Avoid forceful stretching. Go slow and pain-free.

• Arch up → drop down slowly
• 10–15 repetitions
• Reduces stiffness and improves spinal mobility
⸻
3. Side Trunk Stretch

• Hold 20 seconds × 3 each side
• Good for oblique muscle spasm
⸻
4. Knee-to-Chest Stretch
• Lie on back → Bring knees to chest
• Hold 20 seconds
• Releases lower back tension
⸻
B. Strengthening Exercises (for prevention & long-term support)
1. Pelvic Tilt

• Hold 5 sec × 10–12 reps
Strengthens deep core muscles → reduces recurrence of spasm.
⸻
2. Bridge Exercise

• Hold 3 sec × 10 reps
Improves trunk control & reduces spasm frequency.
⸻
🟦 For Neurological Conditions (CP, Stroke, ASD with tone imbalance)
If spasm is due to neurologic causes:
• Rhythmic trunk rotation
• Weighted deep pressure vest (reduces involuntary spasm)
• Slow vestibular input (rocking on therapy ball)
• Trunk co-activation exercises on physioball
⸻
⚠️ When to Be Cautious
Seek evaluation if:
• Spasm with numbness-tingling
• Loss of balance or control
• Spasm lasts for 1 week
• Post-surgery or spinal injury
