Q

Describe the pathogenesis of OA

A

1) chondropathy : cartilage softening and thinning; failure of chondrocytes to control degradation and repair of cartilage
2) subchondral changes : bone structure changes, bone remodeling is disorganized, increase in abnormal type I collagen
3) synovial membrane changes : hyperplasia of the synovial membrane

35
Q

Describe the NEMEX training

A

Neuromuscular exercise training program for patients with knee or hip osteoarthritis after total joint replacement based on principles of neuromuscular training with the aim of improving sensorimotor control and achieving compensatory functional stability. It takes place in groups under the supervision of a physical therapist.

Consists of 3 parts :
- warm up : ergo meter cycling for 10 mn to perceived exertion of somewhat hard
- circuit program : 4 exercises circles with key elements, core stability/postural function, postural orientation, lower extremities muscle strength and functional exercises. 2 exercises per circle, perform 2-3 sets X 10-15 reps and rest time corresponding to one set in between set and exercises.
3 levels of progression given.
- cooling down : walking exercises forward and backward about 10 meters in each direction, mobility exercises in the lower extremities, stretching exercises for lower extremities muscles for a total of 10 mn

36
Q

What are the NEMEX core stability/ postural function exercises

A
  • Pelvic lift with feet on Swiss ball
  • sit ups on Swiss ball
37
Q

What are the NEMEX exercises for postural orientation ?

A
  • standing slide forward backward (in a lunge with slider)
  • standing slide sideways (with slider)
38
Q

What are the NEMEX exercises for lower extremity muscle strength ?

A
  • For hip abductors and adductors : crab walks with t-band around legs
  • for knee extensors and flexors : siting knee extension with t-band around legs
39
Q

What are the NEMEX functional exercises ?
