Neuromuscular Characteristics and Physical Function in Participants with Parkinson’s Disease

PURPOSE: This study aimed to investigate the level of physical function, lower body strength, and muscle activation during various types of muscle contraction in participants with and without Parkinson’s disease (PD).METHODS: Twelve participants with PD (mean age=63.17±6.24 years) and 12 age- and sex-matched healthy adults (mean age = 58.67±6.39 years) were recruited. An isokinetic dynamometer was used to measure the length- and velocity-dependent maximum voluntary force and the rate of torque development (RTD) of the knee extensor muscles. Muscle activation of the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) muscles of both legs was examined using surface electromyography. The 6-minute walk test, chair stand test, timed up-and-go test, sit-and-reach test, and back-scratch test were performed to assess physical function.RESULTS: Compared to healthy individuals, participants with PD showed significantly lower maximum voluntary force and RTD (p<.05), performed fewer repetitions in the chair stand test (11.64±1.75 vs. 17.08±2.27, p<.001), were slower in the timed up-andgo test (8.36±1.42 vs. 5.65±1.07, p<.001), and walked shorter distances in the 6-minute walk test (424.17±65.97 vs. 539.47±63.18, p<.001). However, activation of the three different muscles during isometric and isokinetic muscle contraction was not different between participants with and without PD.CONCLUSIONS: Preserved muscle activation and significantly lower muscle strength during various types of muscle contractions may suggest lower muscle strength and efficiency. The lower physical function seen in participants with mild PD could be due to disease and low physical activity-related muscle atrophy rather than lower muscle activation.

Abstract Fibromyalgia is a chronic pain condition that is frequently accompanied by comorbid conditions, including depression. Depression is associated with reduced physical functioning and health disproportionately affecting middle-aged and older adults with fibromyalgia. This study examined depressive symptoms as a mechanism through which FM status is associated with BMI and physical performance among adults in mid-to-late-life. Participants included 250 community-dwelling middle-aged and older adults (82% female) with (59%) or without (41%) fibromyalgia (M age = 64.44, SD = 9.16). Depressive symptoms were measured using the Beck Depression Inventory-II, BMI was objectively assessed, and physical performance was measured using the Fullerton Advanced Balance scale, 6-Minute Walk Test, 30-Second Chair Stand, and 8-Foot Up and Go Test. Physical performance measure analyses were adjusted for age. Asymptotic mediation analyses revealed that fibromyalgia status was indirectly associated with higher BMI (95% CI [.18, 16.74]), and poorer performance in the Fullerton Advanced Balance (CI [-2.93, -1.24]), 6-Minute Walk Test (CI [-73.75, -35.35]), 30-Second Chair Stand (CI [-2.45, -1.16]), and 8-Foot Up and Go test (CI [.35, .92]) via depressive symptoms. Participants with fibromyalgia reported greater depressive symptoms which was subsequently associated with greater BMI and reduced physical performance. Findings support depressive symptoms as one factor through which fibromyalgia status is associated with higher obesity risk and reduced physical function in middle-aged and older adults with fibromyalgia. This study supports fibromyalgia status as a critical consideration when evaluating the health and disability risk of aging adults.

Aktivitas fisik akan meningkatkan kebugaran jasmani sehingga dapat memperlambat perkembangan kognitif dan penurunan fisik lansia dengan demensia. Demensia merupakan sindrom neurodegeneratif yang timbul karena adanya kelainan bersifat kronis dan progesif disertai dengan gangguan fungsi luhur multipel seperti kalkulasi, kapasitas belajar, bahasa, dan mengambil keputusan. Penelitian ini bertujuan untuk mengetahui kebugaran jasmani lansia dengan demensia pasca aktivitas fisik dengan senam vitalisasi otak. Metode yang digunakan dalam penelitian ini yaitu Metode Experimental. 10 subjek yang berusia 60 – 85 tahun dengan demensia ringan diberi perlakuan senam vitalisasi otak selama 12 kali dengan durasi waktu 25 menit. Setelah melakukan aktivitas fisik dilakukan pemeriksaan tes kebugaran jasmani (testing the elderly) yang terdiri dari: 6 minutes walk test (6 MWT), flexibility: Chair seat and reach test (CSRT), Muscle strength and endurance: Chair stand test (CST), dan Arm curl test (ACT), koordinasi dan kelincahan, 8 Foot up and go test (8 FUGT). Hasil penelitian dengan menggunakan uji T menunjukkan bahwa tes kebugaran memberikan hasil yang signifikan pada tes CST, CSRT (p value 0,0296) dan 8 FUGT 6MWT (pvalue 0,0229) pada tingkat kepercayaan 95%. Kesimpulannya, aktivitas fisik vitalisasi otak berpengaruh terhadap kebugaran jasmani dengan perbaikan tonus otot dan kognitif pada lansia dengan demensia.
