3
Etiology:
The term PD is used to refer to a group of disorders that produce the abnormalities of BASAL GANGLIA function.
Idiopathic parkinsonism most common form.
Secondary parkinsonism caused by virus, toxins, drugs, tumors.
- Physical rehab 5th edition by susan B, o’sullivan.
04/11/2023
Pathophysiology:
4
The basal ganglia (BG) are a collection of
interconnected gray matter nuclear masses deep within
the brain.
Caudate and lentiform nucleus (collectively termed the
striatum ) plus the Subthalamic nucleus and the
substantia nigra(pc).
Degeneration of dopaminergic neurons that produce
dopamine and cell bodies in SNpc.
04/11/20235
Loss of dopamine results in :
An overactive indirect pathway that is thought to underlie akinesia and rigidity.
An underactive direct pathway is thought to be responsible for bradykinesia.

Tremor
A neuroprosthesis for tremor management
through the control of muscle co-contraction
Authors: Juan Alvaro Gallego, et.al
Published year: 2013
Journal: Journal of NeuroEngineering and
Rehabilitation
04/11/2023
14
Objective: Pathological tremor is the most prevalent
movement disorder, which makes tremor a major
cause of loss of quality of life. Therefore, novel
forms for tremor management are required.
Research design: Pre-post experimental design.
04/11/2023
15
Method: A neuroprosthesis that regulated the level of
muscle co-contraction by injecting the current at a pair of antagonists through transcutaneous
neurostimulation was used.
6 patients suffering from parkinsonian or essential
tremor of different severity were taken, and the effect
of the neuroprosthesis during standard tasks was
evaluated.

16
04/11/2023
17
Results: The neuroprosthesis attained significant
attenuation of tremor and reduced its amplitude.
04/11/2023
18
Conclusions: This study sets the basis for the
validation of the neuroprosthesis as an alternative,
non-invasive means for tremor management.

Objective: To understand the effects of action observation on the spontaneous rate of finger movements in patients with
Parkinson disease.
Methods: 38 pts with PD and 14 healthy controls, were
randomly divided into 2 groups.
All participants performed a finger sequence at
their spontaneous pace at different intervals.
04/11/2023
21
04/11/2023
22
Results: Both VIDEO and ACOUSTIC training
increased the spontaneous rate in all participants.
Conclusions: The findings suggest that the
dopaminergic state contributes to the effects of action
observation, and the training may be a promising
approach in the rehabilitation of bradykinesia in PD.

24
Objective: To test the feasibility and effects of
Audio-Biofeedback training modality
in patients with PD.
04/11/2023
25
Method: Seven patients with PD were included in a
study,that comprised of a six weeks intervention
program.
The training was individualized to each
patient’s needs and was delivered using an audio-
biofeedback (ABF) system with headphones.
04/11/2023
26
The device is worn on the patient’s lower back and is attached to headphones by which he hears the auditory feedback.
04/11/2023
27
Results: The ABF system was well accepted by all
participants, with high satisfaction with the
training. A significant improvement of balance,
was observed.
In addition, the training appeared to
have a positive influence on psychosocial aspects
of the disease and the level of depression.
04/11/2023
28
Conclusion: Audio-biofeedback training for
patients with PD is feasible and is associated with
improvements of balance and several psychosocial
aspects.

Aims. To survey falls beyond home, identifying
challenges amenable to behavior change.
Methods: They distributed 380 questionnaires to
PwP in Southern England, asking participants to
count and describe falls beyond home in
the previous 12 months.
04/11/2023
63
Results: Among 255 responses, 136 PwP reported
falling beyond home.They described 249 falls in detail,
commonly falling forward after tripping in streets.
Single fallers (one fall in 12 months) commonly
missed their footing, walking, or changing position and
recovered to standing alone or with unfamiliar help.
Repeat fallers (median falls, two) commonly felt
shaken or embarrassed and sought medical advice.
Very frequent fallers (falling at least monthly; median
falls beyond home, six) commonly fell backward, in
shops and after collapse but often recovered to
standing alone.
04/11/2023
64
Conclusion: Even independently active PwP who do not
fall at home may fall beyond home, often after tripping.
Falling beyond home may result in psychological and/or
physical trauma (embarrassment if observed by strangers
and/or injury if falling backwards onto a hard surface).
Hence prevention requires vigilance and preparedness:
slowing down and concentrating on a single task might
effectively prevent falling.

improving balance and
gait and that the
improvement in gait
performances was
partially maintained
also after 1 year.
04/11/2023
68
Gait:
Robotic gait training is
not superior to equal
intensity treadmill
training for improving
walking ability in patients with mild to
moderate Parkinson’s
disease.
