Focus of Treatment	Treatment	Milestones
ROM	Exercise bike for 5–10 minutes (lower seat height as able; no resistance until able to perform full revolution at lowest seat height, then increase to elicit “somewhat hard” on Borg scale of perceived exertion) Continue ROM, increasing angle, frequency, and intensity until milestones are achieved	Consistent with carryover of AROM 0° to greater than 115°
NMES	As needed
Volitional strength	Continue to progress exercises if able to perform 3 sets of 10 reps of the exercise correctly with maximum fatigue Progression: from 8-RM to 10-RM; reassess 10-RM weekly and exercise at 65% to 70% at 10-RM Exercise examples: leg press and leg extension at 65% to 70% at 10-RM; 4-way hip exercises with resistance	Steady increase in MVIC
Gait retraining	Walking on treadmill at 3.5 km/h for 5 minutes and over ground for 3 minutes Progression: use mirror to provide feedback if needed; decrease mirror reliance, increase speed, increase incline if needed Dosage: 8 minutes	Patient should be able to walk at 4.4 km/h for 5 to 10 minutes without visible asymmetries
Sit-to-stand	Commence from plinth, without upper limb support and with each foot on either side of the Balance Board; plinth should be set so that knee flexion is less than 90° Patient attempts to maintain 50% weight bearing through each limb; allow 5% error Dosage: 3 sets of 10 repetitions Progression: when patient is able to complete 8 of 10 attempts with less than 5% error, decrease height of plinth to allow 90° of knee flexion, then more than 90° of knee flexion Progression: when patient is able to complete 8 of 10 attempts with less than 5% error and plinth at a height so that knee flexion is greater than 90°, repeat with 70% weight on operated limb	Patient should be able to complete sit-to-stand from plinth (90° of knee flexion) with symmetrical weight bearing at least 8 of 10 times in each of 3 sets
Squats on balance board	Stand and squat against wall, keeping weight symmetrically balanced between limbs (50% weight bearing on each limb; 5% error) (usual precautions: ball and chair) Dosage: 3 sets of 10 repetitions to 90° Progression: increase weight bearing on operated limb throughout movement	Patient should be able to bend to 90° with symmetrical weight bearing between limbs and bend to 90° with 90% weight bearing through operated limb
Stair ascent	Commence stair ascent/descent when patient has completed SymSlide progressions Step-ups to 15-cm step Encourage adequate knee flexion, reliance on operated limb to elevate body weight, minimal trunk compensations Dosage: 3 sets of 10 step-ups Progression: increase step height to 20 cm, then 25 cm; decrease handrail use; increase speed	Patient should be able to ascend 15-cm step 8 of 10 attempts, with handrail for balance only
Stair descent	Step-downs from 15-cm step Encourage adequate knee flexion, minimal trunk compensations Dosage: 3 sets of 10 step-downs Progression: increase step height to 20 cm, then 25 cm; decrease handrail use; increase speed	Patient should be able to descend 15-cm step 8 of 10 times, with handrail for balance only
