Parkinson's Case Study - Nick Post-Treatment Assessment
Assessment Results and Comments
|Comments on Parkinsonian features of gait||Post-Treatment||Comments|
over cut off score (falls risk)
|Initiates gait immediately on standing; generally more flexed posture with reduced left arm swing and slow walk; watches for turning point; tremor both hands; six step for 180° turn (falls risk). Good step length and clearance of feet except on turn.||16.46 secs
12.36 secs (below cut off, so safer walk)
|First attempt slow and conscious to maintain good long steps; forgot speed!
Second attempt able to stride out better; 4-step turn
|Motor on motor dual task||15.20 secs (not > 10% so the dual task does not increase falls risk)||Pushes up from chair; pauses before initiating gait; passes turn point as looking up. 4 step turn||13.75 secs (> 10% of baseline so dual task increases falls risk when tired)||Pushes up from chair on second attempt, as did not wait for ‘go’ command; straighter; 6-step pivot turn with adjustment steps.
Note he is becoming tired and his knee aches on right
|Cognitive on motor dual task||15.40 secs (not > 10%)||Even less arm swing; pauses before initiating gait; 5 step turn; less symmetry between steps||14.39 secs
(> 10% of baseline so dual task increases falls risk when tired)
|Steps forward 3m||6 steps||Confident, large steps||6 steps||More upright|
|Steps backwards 3m||8 steps||Drags feet backwards – can hear the scuffing during all steps||6 steps||More extension of trunk and right hip; only dragging right foot back. Nick stated he felt more even with his steps|
TUG and Gait
The lack of extension from both buttocks is most noticeable in the backward stepping, but post-treatment his trunk posture is more upright, plus steps are larger and initiated from his buttock muscles, demonstrating better motor control and balance, so he equals the number of steps forwards and decreased on stepping back (thus giving bigger steps).
The treatment session was effective in improving mechanical pressure and proprioceptive sensory feedback through Nick’s joints allowing better alignment of his body so (until he became tired), the treatment relieved his knee pain.
His TUG baseline post treatment was within the cut-off time as not only a better ability to recruit muscle fibres to power walking, but more confident to step out faster due to relieved pain. However, although all post treatment times were better, adding the second task when he was able to walk faster made the time >10% of baseline, meaning there was increased interference, and hence a falls risk by adding the second task.
Tragus to wall test
|Test: Tragus to wall
(Nick’s optimal is 15 cms +/- 3 cms)
|Pre-treatment||26 cms – outside chest base||24 cms – outside chest base|
|Post-treatment||16 cms – within optimal measure||18 cms – just within optimal measure|
