Musculoskeletal Problems Affect the Quality of Life of Patients with Parkinson's Disease

Effectivenss of electroacupuncture for skeletal muscle pain in Parkinson's disease: a Clinical randomized controlled trial

OBJECTIVE

To explore the effect of electroacupuncture on skeletal muscle pain in Parkinson's disease (PD).

METHODS

A single-center randomized controlled trial was conducted with sixty patients with Parkinson's disease with skeletal muscle pain were randomly divided into electroacupuncture group and sham acupuncture control group with 30 patients each. The electric acupuncture group was treated with electric acupuncture, while the control group was treated with Park needle pseudoacupuncture. Both groups were treated 5 times a week for a total of 4 weeks, and both groups completed 20 treatments. King's Parkinson's Pain Scale (KPPS) and visual analog scale (VAS) were used before and after treatment to evaluate the pain degree of patients. Real-time shear wave elastography (SWE) and modified Ashworth score (MAS) were used to evaluate the changes of muscle tone. Parkinson's comprehensive Score Scale (MDS-UPDRS, including UPDRSⅡ and UPDRS Ⅲ) was used to evaluate exercise ability. Hamilton Depression Scale (HAMD) score was used to evaluate the emotional changes of patients. Spearman correlation analysis was used to explore the correlation between pain degree and muscle tone, exercise ability and emotion.

RESULTS

During the study, one case fell off in the control group, and 30 cases were eventually included in the analysis and treatment group and 29 cases in the control group. After treatment, Young's modulus of biceps and quadriceps and shear wave velocity of biceps were decreased in electroacupuncture group compared with before treatment, while KPPS score, VAS score, UPDRSⅡ, UPDRS Ⅲ and modified Ashworth score were decreased, with statistical significance (P < 0.05). There was no statistical significance in control group (P > 0.05). After treatment, KPPS score, VAS score, UPDRSⅡ and UPDRS Ⅲ, MAS, HAMD score, Young's modulus of biceps and shear wave velocity in electroacupuncture group were significantly lower than those in control group (P < 0.05). Spearman correlation analysis showed that KPPS score was positively correlated with UPDRS Ⅲ (r = 0.414, P < 0.05). KPPS score was positively correlated with HAMD score (r = 0.576, P < 0.01).

CONCLUSION

Electroacupuncture therapy can effectively improve skeletal muscle pain in patients with Parkinson's disease, reduce the muscle hardness of patients, improve patients' daily life ability, and improve patients' emotional disorders. The degree of skeletal muscle pain in PD patients is correlated with motor ability and emotional disorders, but there is no significant correlation between the degree of skeletal muscle pain and the muscle tone of PD patients.

Total knee arthroplasty in patients with Parkinson's disease: A systematic review and meta-analysis protocol

BACKGROUND

Parkinson's disease (PD) patients have been shown to have various musculoskeletal problems, the postoperative outcomes of total knee arthroplasty procedure might be less predictable if performed on a patient who has PD. We conducted a protocol for systematic review and meta-analysis to evaluate the functional outcomes, activity levels, mortalities, implant survival rates, and complications of total knee arthroplasty in patients with PD.

METHODS

This study follows the guideline of the preferred reporting items for systematic reviews and meta-analyses protocols and has been registered on the International Prospective Register of Systematic Reviews with CRD42022375885. Two independent reviewers will search for databases including PubMed, Embase, Cochrane Library website, ClinicalTrials.gov databases, Chinese National Knowledge Infrastructure Database, Wanfang database, and VIP database using the search strategies recommended by the Cochrane Back Review Group. The RevMan 5.3 software (Cochrane Collaboration, Oxford, UK) will be used to conduct the meta-analyses.

RESULTS

The results of this systematic review will be published in a peer-reviewed journal.

CONCLUSION

This study may provide evidence for the clinical application of total knee arthroplasty in patients with PD.

The Efficiency of Spa Rehabilitation in Chronic Ischemic Stroke Patients-Preliminary Reports

Background: Rehabilitation-oriented therapy after a stroke must continue in various forms as a life-long effort. Aim: The study investigated the impact of spa rehabilitation on the quality of life and functional efficiency in patients after an ischemic stroke at a chronic stage of recovery. Methods: The assessment was carried out in a spa resort in southeastern Poland. It involved 32 patients with strokes who participated in a three-week rehabilitation program. Three examinations were performed: upon admission, on the day of discharge and at a two-month follow-up. The quality of life and functional efficiency were assessed with the WHOQOL-BREF and Barthel Index. Results: The quality of life was significantly higher in Exam II compared with Exam I (p < 0.001), and improvement was retained at the follow-up. The Barthel scores were higher in Exam II compared with Exam I (79.84 vs. 68.59), while the differences between the scores in Exams II and III were small (p = 0.039). Conclusions: Three-week spa rehabilitation seems to favorably affect the functional efficiency and quality of life after a stroke. The effects appear to be long-term. The gender, age and time from stroke onset do not seem to impact short-term effects. However, long-term effects are related to the time from stroke onset.

Quality of life of older adults in two contrasting neighbourhoods in Accra, Ghana

As is the case elsewhere in sub-Saharan Africa, Ghana is experiencing a rapid increase in the population of older adults. Despite their rising numbers, the living conditions and wellbeing of older Ghanaians remain woefully understudied. This paper presents the results of a study exploring the quality of life (QoL) of older adults in two contrasting neighbourhoods in Accra, Ghana. The objectives of the study were to: (1) explore and compare the QoL of older slum and non-slum dwellers in Ghana; and (2) determine the extent of QoL disparities between slum and non-slum older adults. To accomplish these objectives, we undertook a cross-sectional survey of older adults (N = 603) residing in a slum and non-slum neighbourhood. QoL was self-assessed in four domains - physical, psychological, social, and environment - using the World Health Organization (WHO) QoL assessment tool (WHOQoL-BREF). Multivariable linear regression analyses of the data revealed no statistically significant difference between the slum and non-slum respondents in physical (coeff: 0.5; 95% CI: -1.7, 2.8; p = 0.642) and psychological (coeff: -0.2; 95% CI: -3.0, 2.6; p = 0.893) QoL. However, the slum respondents reported significantly higher social QoL than the non-slum respondents (coeff: -3.2; 95% CI: -5.6, -0.8; p = 0.010), while the reverse was true in environmental QoL (coeff: 4.2; 95% CI: 2.3, 6.2; p < 0.001). The existence of strong social support systems in the slum and better housing and neighbourhood environmental conditions in the non-slum may have accounted for the observed variation in social and environmental QoL. Thus, contrary to popular discourses that vilify slums as health-damaging milieus, these findings offer a more nuanced picture, and suggest that some features of slums may constitute important health resources for older adults.

Sheth M, Viswanath O, Urits I. Chronic Pain Treatment Strategies in Parkinson's Disease

Neurological disorders, including Parkinson’s disease (PD), have increased in prevalence and are expected to further increase in the coming decades. In this regard, PD affects around 3% of the population by age 65 and up to 5% of people over the age of 85. PD is a widely described, physically and mentally disabling neurodegenerative disorder. One symptom often poorly recognized and under-treated by health care providers despite being reported as the most common non-motor symptom is the finding of chronic pain. Compared to the general population of similar age, PD patients suffer from a significantly higher level and prevalence of pain. The most common form of pain reported by Parkinson’s patients is of musculoskeletal origin. One of the most used combination drugs for PD is Levodopa-Carbidopa, a dopamine precursor that is converted to dopamine by the action of a naturally occurring enzyme called DOPA decarboxylase. Pramipexole, a D2 dopamine agonist, and apomorphine, a dopamine agonist, and Rotigotine, a dopamine receptor agonist, have showed efficacy on PD-associated pain. Other treatments that have shown efficacy in treating pain of diverse etiologies are acetaminophen, Nonsteroidal anti-inflammatory drugs (NSAIDs), and cyclooxygenase-2 (COX-2) inhibitors. Opioids and opioid-like medications such as oxycodone, morphine, tramadol, and codeine are also commonly employed in treatment of chronic pain in PD. Other opioid related medications such as Tapentadol, a central-acting oral analgesic with combined opioid and noradrenergic properties, and Targinact, a combination of the opioid agonist oxycodone and the opioid antagonist naloxone have shown improvement in pain. Anticonvulsants such as gabapentin, pregabalin, lamotrigine, carbamazepine and tricyclic antidepressants (TCAs) can be trialed when attempting to manage chronic pain in PD. The selective serotonin and noradrenaline reuptake inhibitors (SNRIs) also possess pain relieving and antidepressant properties, but carry less of the risk of anticholinergic side effects seen in TCAs. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been shown in multiple studies to be effective against various types of PD associated pain symptoms. Massage therapy (MT) is one of the most common forms of complementary and alternative medicine. Studies have shown that pressure applied during MT may stimulate vagal activity, promoting reduced anxiety and pain, as well as increasing levels of serotonin. In a survey study of PD patients, rehabilitative therapy and physical therapy were rated as the most effective for pain reduction, though with only temporary relief but these studies were uncontrolled. Yoga has been studied for patients with a wide array of neurological disorders. In summary, PD pathology is thought to have a modulating effect on pain sensation, which could amplify pain. This could help explain a portion of the higher incidence of chronic pain felt by PD patients. A treatment plan can be devised that may include dopaminergic agents, acetaminophen, NSAIDs, opioids, antidepressants, physical therapies, DBS and other options discussed in this review. A thorough assessment of patient history and physical examination should be made in patients with PD so chronic pain may be managed effectively.

Sex-specific effects of subthalamic nucleus stimulation on pain in Parkinson's disease

OBJECTIVE

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is known to reduce motor symptoms of Parkinson's disease (PD). The effects of DBS on various nonmotor symptoms often differ from patient to patient. The factors that determine whether or not a patient will respond to treatment have not been elucidated. Here, the authors evaluated sex differences in pain relief after DBS for PD.

METHODS

The authors prospectively evaluated 20 patients preoperatively and postoperatively after bilateral STN DBS with the validated numeric rating scale (NRS), Revised Oswestry Disability Index for low-back pain (RODI), and King's Parkinson's Disease Pain Scale (KPDPS) and assessed the impact of sex as a biological variable.

RESULTS

The cohort consisted of 6 female and 14 male patients with a mean duration of 11.8 ± 2.0 months since DBS surgery. Females were significantly older (p = 0.02). Covariate analysis, however, showed no effect of age, stimulation settings, or other confounding variables. KPDPS total scores statistically significantly improved only among males (p < 0.001). Males improved more than females in musculoskeletal and chronic subsets of the KPDPS (p = 0.03 and p = 0.01, respectively). RODI scores significantly improved in males but not in females (p = 0.03 and p = 0.30, respectively). Regarding the NRS score, the improvements seen in both sexes in NRS were not significant.

CONCLUSIONS

Although it is well recognized that pain complaints in PD are different between men and women, this study is unique in that it examines the sex-specific DBS effects on this symptom. Considering sex as a biological variable may have important implications for DBS pain outcome studies moving forward.

Clinical Perspectives of Parkinson's Disease for Ophthalmologists, Otorhinolaryngologists, Cardiologists, Dentists, Gastroenterologists, Urologists, Physiatrists, and Psychiatrists

Parkinson's disease (PD) is a multisystemic disorder characterized by various non-motor symptoms (NMS) in addition to motor dysfunction. NMS include sleep, ocular, olfactory, throat, cardiovascular, gastrointestinal, genitourinary, or musculoskeletal disorders. A range of NMS, particularly hyposmia, sleep disturbances, constipation, and depression, can even appear prior to the motor symptoms of PD. Because NMS can affect multiple organs and result in major disabilities, the recognition and multidisciplinary and collaborative management of NMS by physicians is essential for patients with PD. Therefore, the aim of this review article is to provide an overview of the organs that are affected by NMS in PD together with a brief review of pathophysiology and treatment options.

An overview of pain in Parkinson's disease

Pain is a common non-motor symptom of Parkinson's disease (PD) and the prevalence of pain among PD patients varies because of the disease stage, co-morbidities, and evaluating tools. Risk factors for pain in PD include an early age of onset, long disease duration, motor complications, concomitant depressive symptoms, female gender, and associated medical conditions. In patients with PD, pain can be classified as musculoskeletal pain, chronic body pain (central or visceral), fluctuation-related pain, nocturnal pain, orofacial pain, pain with discolouration/oedema/swelling, and radicular/neuropathic pain; musculoskeletal pain as the most common type. Potential underlying mechanisms include a disruption of peripheral nociception and alterations in central pain threshold/processing. Genetic polymorphisms in genes that confer pain susceptibility might also play a role in the occurrence of pain in PD. In advanced stage of patients with PD, polyneuropathy could occur in patients using high dosage of levodopa. Pain often correlates to other non-motor symptoms of PD, including depression, sleep, and autonomic symptoms. Dopaminergic drugs, non-dopaminergic medications, botulinum toxin, deep brain stimulation, and physiotherapy have shown some benefits for certain types of PD-related pain. An increased awareness of pain as a common non-motor symptom of PD provides further insights into sensory system dysregulation in this disease. In this review, we aim to summarizes the clinical features of pain in patients with PD and emphasize the latest evidence of pain related to levodopa treatment.
