Hamstring Rehabilitation Guidelines

Neuromuscular Control Exercises

  • Unstable surface training using balance pads or foam rollers improves knee joint proprioception, particularly effective in early and intermediate rehabilitation phases 2, 3
  • Single-leg dynamic balance exercises challenge postural control and increase hamstring muscle activation 2
  • Backward walking on an inclined treadmill is part of comprehensive motor control programs 2, 3
  • Plyometric exercises, including running, jumping, and agility activities, provide additional benefit during advanced rehabilitation phases for subjective function and functional outcomes 2, 3
  • Sport-specific exercises integrated into neuromuscular training programs 2, 3
  • The combination of plyometric and eccentric training demonstrates superior improvements in balance, subjective function, and functional activities compared to either method alone 2, 4

Concentric Strengthening Exercises

  • Traditional hamstring curls performed at 8-12 repetitions for adults under 50-60 years, or 10-15 repetitions at reduced resistance for older individuals 5
  • Moderate repetition duration: 3 seconds concentric phase, 3 seconds eccentric phase 5
  • Single-set programs performed minimum 2 days per week are highly effective and promote adherence during initial training 5
  • Exercises should be performed through full range of motion at moderate to slow controlled speed, avoiding breath-holding 5

Progression Strategy

  • Start with isometric exercises in the first postoperative week (if not causing pain) 1, 6, 7
  • Progress to concentric exercises after the initial phase 1, 6, 7
  • Eventually advance to eccentric exercises in closed kinetic chain 1, 6, 7

Evidence on Effectiveness

  • Both concentric and eccentric training improve quadriceps and hamstring strength without significant differences between training types 2, 4
  • Strength training should be augmented with neuromuscular and motor control re-education exercises for optimal outcomes 1, 6, 7, 4
  • Both motor control and strengthening modules significantly improve quadriceps and hamstring strength when combined 2, 3
  • Balance and proprioception training show no difference in subjective function or functional outcomes compared to strength training alone, but the combination is recommended 2, 3

Stretching for Flexibility

  • Hold duration: 15-30 seconds per stretch, 2-4 repetitions per stretch, performed 2-3 days per week 5, 8
