Bringing specificity to your rehab programs

The Decline Board allows far greater specificity in rehabilitating tendon injuries around the knee and ankle (1).

When performing a standard squat, calf tension and excessive trunk flexion can often act to unload the knee extensors (quadraceps). Over time, specific weakness of the quadraceps muscle-tendon unit is considered to increase susceptibility of injury to the knee extendors to be loaded maximally.


A recent study of rehabilitation programs for elite volleyballer players with jumper's knee found that using the Decline Board produced superior strength gains and improvements in tendon pain compared to a standard squat program (2).

The Decline Board allows targeted strengthening of the knee extensors ot achievable in a standard squat, and is a valuable tool in rehabiitation and strengthening of the knee extensor mechanism.

The Decline Board is also used for calf strenthening and stretching, providing added load through range during strengthening and a functional base to passivley stretch specific regions of the calf complex.


Suggested Protocols

      Warning: Exercise prescription is dependant on many factors, including base strength, flexibility and severity of injury. It is essential that these factors are taken into consideration when formulating a rehabilitation program.

      Please consult a health professional before undertaking any rehabilitation program.

Typical Rehabilitation protocols:

Patellar Tendon

      • Single leg
      • 1-2 sec up/down
      • 2-3 sets of 15-20 reps
      • Assisted return with other leg
      • 1 min rest b/w sets
      • 1 / day sessions

Quadriceps hypertrophy

      • Single leg
      • 4-5 sets of 6-12 reps
      • 3 sec up/down
      • 30 sec rest b/w sets
      • 3/ week sessions

Calf flexibility

      • 30-60 sec holds in 3 directions (see diagram)
      • 2-3 times daily

Recommended under the guidance of a professional practitioner.

The Decline board was designed by Craig Purdam and Dr Jill Cook, two of Australia's leading experts in tendon pain, and developed at the Australian Institute of Sport.
