A Case Study about Progressive Supranuclear Palsy

Intervention

While understanding that William presented with PSP symptoms such as impaired balance leading to falls, axial rigidity, and muscle stiffness, it is important to note that William was not considered “severe” and can follow similar treatment guidelines to Idiopathic Parkinson’s disorder as certain treatment techniques have shown to positively benefit both disorders.

Our intervention approach aimed to be client-centered by creating specific short-term and long-term goals based on William’s current phenotype and problem list, while maintaining an evidence-based intervention style. It was important to attempt to get William back to doing his regular routine within limits, such as walking his dog, and participating in his bingo sessions. With these factors in mind, an intervention program was developed.

The intervention program involved short-term and long-term goals for the following ICF domains:

1. Body Function and Structure
2. Participation
3. Activities

The goals for each domain are listed below:

Short-term Goal #1 for Body Function and Structure:

William will score at least 38 on the Berg Balance Scale after 4 weeks of Physiotherapy.

Long-term Goal #1 for Body Function and Structure:

William will be able to walk his dog again with no falls, and the assistance of a mobility aid, after 5 months of physiotherapy.

Short-term Goal #2 for Participation:

William will be able to maintain at least 63/100 on the PSP-QoL scale after 3 weeks of Physiotherapy.

Long-term Goal #2 for Participation:

William will be able to navigate to weekly bingo sessions, play independently, and return home safely using his mobility aid after 5 months of Physiotherapy.

Short-term Goal #3 for Activities:

William will be able to complete the TUG test in 25 seconds within 4 weeks of Physiotherapy treatment.

Long-term Goal #3 for Activities:

William will be able to safely travel 400m with his mobility aid, with no complications, after 12 months of Physiotherapy treatment.

Treatment:

First, we recommended that William ideally attended physiotherapy sessions 3 times a week, in order to have the best chance to maintain or improve his current presentation. The core of our treatment involves music-cueing to help facilitate effective gait technique. This form of treatment was conducted in conjunction with regular physiotherapy treatment techniques in order to provide William with the best outcome possible.  (Insert table on physiopedia website with FITT parameters to make it look better, but for now leave out table) Music-cued exercise training has been shown to be an effective and engaging way for individuals with PSP to improve aerobic endurance and retrain gait patterns. Furthermore, it can prove to be an optimal technique for individuals with PSP because the part of the brain responsible for rhythm, are not associated with the basal ganglia which is heavily affected in individuals with PSP.

Physical Therapy sessions consisted of:

• Warm-up (10 minutes)
• Lower limb strengthening (20 minutes)
• Gait training with music (20 minutes)

Warm-up (10 minutes - Choose exercise based on patient’s current presentation)

• Single leg balance each leg 2x20 sec
• Right + Left torso rotation 2x10
• Quad & hamstring stretch 1x20 until feeling of discomfort
• Neck left + right rotation 1x10
• Neck flexion and extensions 1x10
• Heel tapping, hand clapping 1x10

Strengthening plan (20 minutes)

• Scapular squeezes 2x8
• Supported calf raises 2x8
• Knee flexion & extension 3x10 each leg
• Supported sit to stands 3x (to simulate the TUG)

Gait training with music (30 minutes)

• Patients are given a choice of music genre selection ranging from country to pop to classical music, in hopes to increase satisfaction and adherence to the program. Each song choice presented contains a cadence that can be adjusted to the patient's ability level.
• When the music begins, patients listen to the music beats/rhythms and are instructed to perform specific movements on cue with the beat/rhythm heard in the song playing, that relate to walking, or build up to walking techniques, such as knee raises or arm swings.
• Each session, the music can be adjusted to fit the ability of William, and the specific movements performed can be progressed or regress in difficulty.

The Use of Innovative Technology for Individuals with PSP

Innovative technology is being used more frequently as we begin to better understand Progressive Supranuclear Palsy as a disease, and continue to determine the best options for treatment. One example of an innovative technology used for patients with PSP in recent history is the use of gaming systems to facilitate increase in motor control, awareness and improvement in gait patterns. In the specific case of William, the use of this gaming system, specifically the XBox Kinect, several activity-based games could be chosen, therefore tailoring the treatment to the patient. Furthermore, each activity based game can be adjusted in difficulty, and potentially mimic functional tasks based on the goals of the patient. In William’s case, we could use XBox Kinect to improve gait, improve cardiovascular health, and potentially aim to get him walking his dog again, through virtual dog walking games. However, it is important to note that there are some challenges to incorporating these types of technological tools into intervention plans. First, it is important to understand that innovative technology is still a relatively new approach to treatment in individuals with PSP, therefore for patients who are considered elderly, it may present a challenge for them to understand treatment and adhere to the program in general. Furthermore, the platform of XBox Kinect has recently stopped receiving support from its original developer for the development of its product. Although XBox Kinect can facilitate physical activity in a variety of different populations, there is question on how tailored an intervention program can be, especially in clinical practice, if a decreased number of games and updates are being made. Regardless, these challenges can be mitigated by providing an educational seminar to patients interested in XBox Kinect therapy so that they can better understand their treatment options and the technology itself. Additionally, there are other gaming systems that support exercise-based treatment that are consistently being updated. It is possible that if a clinical environment does not deem XBox Kinect to be suitable for use in clinical practice, another platform such as Playstation VR can be used.
