Welcome to another in-depth post on Parkies Unite! In this long-form, step-by-step exploration, we dive into a research study from our conversation above that examines how a Multimodal Exercise Program (MEP)—combining resistance, aerobic, and balance training—affects both functional capacity and quality of life (QoL) in elderly patients with Parkinson’s disease (PD). Below, you’ll find all the details discussed, including the study’s background, methodology, findings, and implications.

Introduction
Parkinson’s disease (PD) is a degenerative neurological illness characterized by various motor symptoms (slowed movement, muscle stiffness, tremors, balance impairment) and non-motor symptoms. These manifestations can progress to significant functional impairment. Recent estimates indicate that PD has become increasingly prevalent, especially among individuals over the age of 50.
The hallmark pathology of PD involves the degeneration of dopamine-producing cells in the substantia nigra, leading to a neurotransmission imbalance in the basal ganglia. Motor impairments such as reduced balance, impaired postural control, lower movement speed, and decreased strength are common. Additionally, patients often face an increased risk of falls, fractures, and a cascade of other complications.
Age-related changes—like a decline in the musculoskeletal, vestibular, somatosensory, and visual systems—further compound these problems. For many with PD, non-pharmacological interventions like tailored exercise are key strategies to boost physical performance and enhance overall quality of life. Here, a Multimodal Exercise Program (MEP) becomes essential, integrating resistance, balance, and aerobic training to improve tasks required for daily life.
Study Design and Participants
This was a quasi-experimental study, centered on elderly female patients in Isfahan, Iran, in 2023. A total of 30 female PD patients with at least three years of disease duration were randomly divided into two groups:
- MEP Group (n=15)
- Control Group (n=15)
All participants had physician consent. Inclusion criteria required being in Hoehn and Yahr stages 2 or 3, responding to PD medications, and having a moderate disease stage per the Unified Parkinson’s Disease Rating Scale. Those with major skeletal injuries or surgeries in the past year, as well as anyone who missed more than 30% of sessions, were excluded.
Demographic Data
| Variable | Group | Mean ± SD | t | p |
|---|---|---|---|---|
| Age (years) | MEP | 60.1 ± 7.6 | 0.162 | 0.67 |
| Control | 60.4 ± 8.2 | |||
| Height (cm) | MEP | 161.3 ± 5.5 | 0.667 | 0.51 |
| Control | 160.1 ± 4.6 | |||
| Weight (kg) | MEP | 67.9 ± 8.8 | 0.670 | 0.41 |
| Control | 68.5 ± 9.8 |
There were no significant differences between groups in age, height, and weight.
Instruments
- Parkinson’s Disease Questionnaire (PDQ-39)
- Assesses patients’ quality of life across multiple dimensions: mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, bodily discomfort.
- Each question is answered on a five-point Likert scale (0 = never, 4 = always). Scores range from 0 to 100, where 0 indicates the best QoL and 100 the worst.
- Static Balance (Sharpened Romberg Test)
- Subjects stand barefoot with one foot in front of the other, arms crossed over the chest, eyes closed. Time in balance is recorded.
- Dynamic Balance (Stand and Walk Test)
- Subjects stand from an armless chair (45 cm high), walk 3 meters, and return to the chair. Completion time is measured.
- Walking Speed
- A 10-meter walk is timed to assess gait performance.
- Wrist Strength
- Measured with a digital hand-held dynamometer, focusing on handgrip strength.
Intervention: Multimodal Exercise Program (MEP)
Participants in the MEP group performed their exercise regimen three sessions per week, for 12 weeks. Each session was 60 minutes, involving:
| Element | Description |
|---|---|
| Warm-up (5-10 min) | Gentle activities to enhance joint mobility, prepare neuro-muscular tissues, and promote functional transitions. |
| Resistance Training | Targeted exercises for facial muscles, shoulders, chest, arms, back, hips, calves, and thighs. Each exercise: 2 sets, 10 repetitions per set. |
| Balance Exercises | Involving seated balance, standing balance (eyes open and closed), and dynamic balance challenges. Each movement: 10-15 seconds, 2 sets. |
| Walking Exercises | – Steady Walking: 1-2 sets, 30-50 steps/set – Walking & Turning: 1-2 rounds per set (total 2 sets) – Obstacle Crossing: 5-10 steps each direction (2 sets) |
The control group did not participate in any structured exercise routine.
Statistical Analysis
- SPSS (v22) was used.
- Shapiro-Wilk test confirmed normal data distribution.
- Repeated Measures ANOVA tested changes within and between groups. Significance was set at p < 0.05.
Results
After 12 weeks, significant improvements were observed in the MEP group for quality of life, static balance, dynamic balance, wrist strength, and walking speed, whereas the control group showed minimal or no improvements.
| Variable | Group | Pre-test (Mean ± SD) | Post-test (Mean ± SD) | Within-Group (t, p) | Between-Group (F, p, Eta) |
|---|---|---|---|---|---|
| Quality of Life | MEP | 105.68 ± 10.82 | 147.63 ± 13.82 | t=183.166, p<0.001 | F=3161.964, p<0.001, Eta=0.99 |
| Control | 104.41 ± 10.42 | 118.98 ± 12.52 | t=153.141, p<0.001 | ||
| Static Balance | MEP | 5.62 ± 1.81 | 10.17 ± 4.12 | t=89.098, p<0.001 | F=44.154, p<0.001, Eta=0.62 |
| Control | 6.52 ± 2.41 | 5.98 ± 1.52 | t=33.816, p<0.001 | ||
| Dynamic Balance | MEP | 14.68 ± 4.52 | 11.17 ± 3.82 | t=124.435, p<0.001 | F=6.872, p<0.01, Eta=0.32 |
| Control | 16.71 ± 5.42 | 16.25 ± 12.52 | t=46.073, p<0.001 | ||
| Wrist Strength | MEP | 59.88 ± 14.62 | 77.27 ± 15.12 | t=18.965, p<0.001 | F=3161.964, p<0.001, Eta=0.99 |
| Control | 64.99 ± 15.31 | 66.24 ± 13.10 | t=0.390, p<0.001 | ||
| Walking Speed | MEP | 12.61 ± 4.62 | 10.05 ± 4.12 | t=53.541, p<0.001 | F=1861.706, p<0.001, Eta=0.98 |
| Control | 12.44 ± 4.42 | 13.26 ± 5.52 | t=8.692, p<0.001 |
Key Points from the Results
- Quality of Life: PDQ-39 scores improved notably more in the MEP group.
- Static & Dynamic Balance: MEP participants demonstrated significant gains—longer time in the Sharpened Romberg, and faster completion on Stand and Walk.
- Wrist Strength: The MEP group showed marked improvement in handgrip strength.
- Walking Speed: Participants in the MEP group walked faster post-intervention, while the control group actually took longer on the 10-meter test.
Discussion
- Balance Improvement: Enhanced static and dynamic balance likely stems from reorganization in neural pathways, improved muscle coordination, and the synergy of aerobic, strength, and balance drills.
- Muscle Strength: PD patients often suffer from tremors, reduced mobility, and lower muscle power. Incorporating strength training significantly boosts muscle capacity in the wrists and lower limbs.
- Walking Performance: PD can limit step length, walking speed, and arm swing. Regularly practicing walking exercises plus obstacle crossing helps break “freezing of gait,” thereby improving fluidity and speed.
- Quality of Life: Ultimately, these combined improvements in motor function bolster everyday independence, social engagement, and self-confidence, all contributing to a higher overall QoL.
Conclusion
A 12-week Multimodal Exercise Program—incorporating resistance, aerobic, and balance elements—offers a powerful complementary strategy to improve quality of life, static balance, dynamic balance, wrist strength, and walking speed in elderly patients with PD. Given that PD is a multifaceted disease affecting both motor and non-motor functions, such comprehensive exercise routines can provide substantial benefits when integrated into standard rehab programs.
Study Limitations
- Sample Size & Location: Only 30 participants from a single city; broader studies with larger, more diverse populations are needed to solidify these findings.
- Short Duration: While 12 weeks yielded notable gains, extended follow-up might show whether benefits are maintained over time.
