CAI Rehab & Treatment Tips

You need to assess joint range, laxity, strength & swelling


 Neuromuscular deficits

Neuromuscular deficits may be manifested as:
Impaired balance
Reduced joint position sense (JPS)
Strength deficits (any mm group)
Decreased ROM (esp DF)
Slower firing of peroneals to inversion perturbation
Slowed nerve conduction velocity
Impaired cutaneous sensation

Treatment & rehabilitation must not only address mechanical stability

but ALSO

Restoration of neuromuscular function

Good evidence for:

1. Both MAI & FAI contribute to CAI.

2. Often still deficits in  Dynamic Postural Control (DPC) at 6 months - they need long term rehab! Patients can benefit from the Ankle Rehab App to increase compiance.

3. CAI patients have a more ‘laterally based foot’ in gait & Fx’l activities. Try to retrain normal foot placement/position.

4. Delayed peroneal reaction time (feedforward system disrupted, ie, not just the feedback systems) – activation & timing issues – not just strength.


6.Train the whole functional range – not just around neutral position – as the JPS & proprioception is especially poor in the inverted position...their area of danger where they need the best recovery of all.

7. Ax & Rehab multi-directional (not uni-planar). Specificity to the activities they need to return to. Variety of movements and challenges.

10.Train both sides – central mediation & cross over within dorsal horn of spinal cord.

11. Challenge all variables when training proprioception

The main situations when CAI get giving way are:
1. When they are distracted, eg looking up at a sign, crossing the road, etc. Their eyes (which are usually compensating heavily for the poor proprioception) are looking elsewhere.
2. Over uneven surfaces such as a field, or over cobblestones.
3. In unmet challenges.

Thus, in rehabilitation:
- look all different directions, not just straight ahead - changes in head position will also change vestibular input.
- train at various body positions (eg, knee bent at different angles, or in lunges/tackle positions, etc).
- incorporate dynamic not just static training,
- various surfaces (eg, mini tramploline, air balance cushion or x2 cushions)
