Pain Reduction and Posture Alignment Improvement in Older Adults with Chronic Low Back Pain: A Novel Approach Using Spinal Thermal Massage Bed and Calf Pneumatic Cell Compression.

BACKGROUND Chronic low back pain (CLBP) significantly affects the well-being of older adults, leading to diminished quality of life and heightened stress. Existing treatments have limited effectiveness and potential side effects. This study aimed to explore an integrative approach, employing a combination of spinal thermal massage bed (STMB) and intermittent pneumatic calf compression, as an alternative strategy for managing CLBP, improving body posture, reducing stress, and enhancing quality of life. MATERIAL AND METHODS Twenty-three participants aged 65-80 years completed a 4-week intervention involving eight sessions (2 per week) with the STMB device. Outcome measures included pain level assessed by the visual analog scale, trunk and pelvic tilting angles indicating spine curvature, stress level of the autonomic nervous system, Oswestry Disability Index, and EuroQol five-dimensions QoL questionnaire. RESULTS The study revealed significant reductions in pain intensity between baseline and mid-term scores (p=0.002) and between baseline and post-test scores (p=0.001). Moreover, notable improvements were observed in trunk and pelvic tilting angles (p<0.001) and stress scores between baseline and mid-term scores (p=0.037) and between baseline and post-test scores (p=0.019). However, no significant changes were observed in disability level or QoL. Participants expressed high satisfaction with the intervention, and no serious side effects were reported CONCLUSIONS This study provides compelling evidence supporting the safety and efficacy of combining STMB with intermittent pneumatic calf compression in reducing pain intensity and stress levels and improving trunk and pelvic tilting angles. Clinical trial number: KCT0008212.

Patient-specific functional electrical stimulation strategy based on muscle synergy and walking posture analysis for gait rehabilitation of stroke patients.

OBJECTIVE: To evaluate a novel multi-channel functional electrical stimulation (FES) rehabilitation method based on the evaluation of patient-specific walking dysfunction. METHODS: This study investigated a novel multi-channel FES-based rehabilitation method that analysed the patient's muscle synergy and walking posture. A patient-specific FES profile was produced in the pre-evaluation stage by comparing the muscle synergy and walking posture of the patient with those of healthy control subjects. During the rehabilitation phase, this profile was used to determine an appropriate FES pulse width and amplitude for stimulating the patient's muscles as they walked across a flat surface. RESULTS: Two stroke patients with hemiplegic symptoms participated in a clinical evaluation of the proposed method involving a 4-week course of rehabilitation. An evaluation of the rehabilitation results based on a comparison of the pre- and post-rehabilitation muscle synergy and walking posture revealed that the rehabilitation enhanced the muscle synergy similarity between the patients and healthy control subjects and their quantitative walking performance, as measured by a 10-m walk test and walking speed, by up to 23.38% and 30.00%, respectively. CONCLUSION: These results indicated that the proposed rehabilitation method improved walking ability by improving muscle coordination and adequately supporting weakened muscles in stroke patients.

Equine Exercise in Younger and Older Adults: Simulated Versus Real Horseback Riding.

Horseback riding is an effective exercise for improving postural control and balance. To reduce costs and improve accessibility, simulated horseback riding has been developed; but no differential effects of simulated and real horseback riding on muscle activation patterns in older adults have been studied. Thus, we compared muscle activation patterns for older and younger adults engaged in real and simulated horseback riding exercises, using surface electromyography recordings of the erector spinae, rectus abdominis, internal oblique abdominis, and rectus femoris muscles. We recorded muscle activity for three riding patterns: walk, slow trot, and fast trot. Muscle activation was uniformly higher for simulated (vs. real) horseback riding and increased from the walking pattern through slow and fast trot. There was no age effect, but among older participants, muscle activation was higher for simulated (vs. real) horseback riding across all gait types. Simulated and real riding produced a similar pattern of muscle activation of the thigh and trunk. These results demonstrate that simulated horseback riding can be an effective alternative to actual riding for increasing trunk and thigh muscle activation and improving postural control and balance, perhaps especially among older adults.

The Effectiveness of Hollowing and Bracing Strategies With Lumbar Stabilization Exercise in Older Adult Women With Nonspecific Low Back Pain: A Quasi-Experimental Study on a Community-based Rehabilitation.

OBJECTIVE: The purpose of this study was to explore the therapeutic effectiveness of hollowing lumbar stabilization exercise (HLSE) and bracing lumbar stabilization exercise (BLSE) for older adult women with nonspecific low back pain (NSLBP) in community welfare centers. METHOD: A total of 38 older adult women with NSLBP were allocated to either the HLSE group (n = 17, 70.4 ± 1.7 years) or the BLSE group (n = 21, 66.8 ± 4.4 years). Both groups performed intervention for 12 consecutive weeks, 3 times per week. Each group performed 5 lumbar stabilization exercises, including side plank exercise, bridge exercise, 4-kneeling exercise, prone plank exercise, and prone back extension exercise with hollowing and bracing strategy, respectively. The baseline and post-test values of trunk strength, low back disability (Korean Oswestry Disability Index [K-ODI] and Korean Roland Morris Disability Questionnaire [K-RMDQ]), and static balance (1-leg standing test) were compared by using per-protocol analysis. RESULTS: In trunk strength, the trunk flexor had significant difference (F = 11.10, P = .001) between groups and within groups of BLSE (t = -5.56, P = .001) and HLSE (t = -2.50, P = .024). Trunk back extensor of HLSE (t = -6.00, P = .001) and BLSE (t = -9.19, P = .001) only had significant within-group difference. However, in trunk side flexor, HLSE and BLSE had only significant difference between groups. In low back disability, K-ODI for HLSE (t = 4.50, P = .001) and BLSE (t = 4.60, P = .001) had significant within-group difference but no significant difference between groups (F = 0.28, P = .202). In K-RMDQ, HLSE only had significant within-group difference (t = 3.97, P = .001). In trunk muscle strength, the effect size of HLSE and BLSE groups for trunk flexor was HLSE -0.53 (medium) and BLSE -1.21 (large); trunk side flexor: HLSE 0.27 (small) and BLSE -0.24 (small); and trunk back extensor: HLSE 1.1 (large) and BLSE 2.00 (large), respectively. In low back disability, the effect size of both groups for K-ODI was HLSE 0.88 (large) and BLSE 1.05 (large), and K-RMDQ, HLSE 0.19 (small) and BLSE 0.40 (small), respectively. CONCLUSION: Our findings suggest that HLSE and BLSE could be recommended for community settings to improve trunk strength and low back disability in older adult women with NSLBP. Especially, HLSE and BLSE could be recommended for elderly women with NSLBP who have lower back disability and weak trunk muscle strength, respectively.

A self-determination theory-based self-myofascial release program in older adults with myofascial trigger points in the neck and back: A pilot study.

PURPOSE: To examine the effectiveness and adherence to a self-determination theory (SDT)-based self-myofascial release (SMR) program in older adults with myofascial trigger points (MTrPs), and to investigate the factors that influence participant behavioral change while conducting the program in a home setting. METHODS: An explanatory mixed-method design was used to evaluate a 12-week SDT-based SMR program, including a 4-week group-based education and practice (EP) phase and an 8-week home-based self-management (SM) phase. Pain intensity on palpation and sensitivity to pain were assessed at baseline and the post EP and post SM phase. Focus group interviews were conducted at the post SM phase. FINDINGS: Fifteen participants completed the study. Pain intensity and sensitivity to pain significantly improved at the post SM phase compared with the baseline. Adherence increased during the SM phase compared with that during the EP phase. Four main themes emerged as factors that influenced participant behavioral change: 1) "awareness of the effectiveness"; 2) "a sense of duty to perform the exercise"; 3) "obedience to expert instruction"; and 4) "lack of friendship." CONCLUSIONS: These results support the effectiveness of an SDT-based SMR program for the treatment of MTrPs and in motivating older adults to participate in the program.

Manipulative rehabilitation applied soon after lumbar disc surgery improves late post-operative functional disability: A preliminary 2-year follow-up study.

BACKGROUND: Studies have shown late post-operative physical disability and residual pain in patients following lumbar disc surgery despite growing evidence of its beneficial effects. Therefore, rehabilitation is required to minimise the late post-operative complications. OBJECTIVE: To assess the feasibility of manipulative rehabilitation to improve late post-operative outcomes. METHODS: Twenty-one patients aged 25-65 years undergoing lumbar microdiscectomy were randomly assigned to the rehabilitation group (n= 14) or active control group (n= 7) by simple randomisation. Eight rehabilitation sessions were initiated 2-3 weeks after surgery. Thirty-minute sessions were conducted twice weekly for four weeks. Post-operative physical disability and pain were assessed at baseline and at the two-year follow-up. RESULTS: Post-operative physical disability improved more in patients who had undergone rehabilitation than in those who had received control care (63% vs. -23%, P< 0.05). Post-operative residual low back and leg pain were alleviated in the treatment group (26% and 57%, respectively), but intensified in the control group (-5% and -8%, respectively). CONCLUSIONS: This study demonstrated the potential of manipulative rehabilitation and importance of post-operative management after lumbar disc surgery. Definitive trials with larger sample sizes are required to confirm the feasibility and potential therapeutic effectiveness of this approach.

Patient perspectives on virtual reality-based rehabilitation after knee surgery: Importance of level of difficulty.

This article explored the perspectives of 25 patients regarding virtual reality (VR)-based rehabilitation following knee surgery and identified the important factors that allowed patients to immerse themselves in rehabilitation. Qualitative analysis of data collected via open-ended questionnaire and quantitative analysis of data from physical assessments and surveys were conducted. In the open-ended questionnaire, the majority of participants mentioned level of difficulty as the most common reason for selecting both the most and the least immersive exercise programs. Quantitative analysis showed that participants experienced a high level of flow (3.9 +/- 0.3 out of 5.0) and a high rate of expectation of therapeutic effect (96%) and intention of exercise adherence (96%). Further, participants with more severe pain or physical dysfunction tended to have more positive experiences (e.g., Difficulty-Skill Balance, Clear Goals, and Transformation of Time), leading to high levels of flow during VR-based rehabilitation. In conclusion, VR-based games are potentially acceptable as a motivational rehabilitation tool for patients following knee surgery. However, to best meet patients' needs, it might be useful to equip a VR program with varied levels of difficulty, taking into account the severity of the individual's knee injury. Additionally, severe pain or physical dysfunction might act as an indication rather than a contraindication for VR-based rehabilitation.

Myofascial Pain Syndrome in the Elderly and Self-Exercise: A Single-Blind, Randomized, Controlled Trial.

OBJECTIVE: This study aimed to demonstrate the effect of self-exercise with a therapeutic inflatable ball (SEIB) in elderly patients with myofascial pain syndrome. DESIGN: Single-blind, randomized, controlled noninferiority trial. SETTING: University campus. PARTICIPANTS: Forty elderly patients with myofascial pain syndrome completed the study. They were randomly allocated to SEIB (n = 22; mean age, 70.23 ± 6.11 years) or ultrasound (US) therapy (n = 18; mean age, 67.99 ± 5.64 years). INTERVENTION: SEIB and US therapy (twice weekly for 4 consecutive weeks). OUTCOME MEASURES: Visual analog scale (VAS), pressure pain threshold (PPT), and cervical lateral flexion (CLF) were measured at baseline and at 1, 2, 3, and 4 weeks. RESULTS: The noninferiority test indicated that SEIB was not inferior to US for VAS, PPT, and CLF. Between-group comparisons showed no significant differences in the VAS (F = 2.579; p = 0.117), the PPT (F = 0.245; p = 0.624), and the CLF (F = 2.072; p = 0.159). In within-group comparisons, both groups presented significant differences in VAS (SEIB after 1 week and US after 1 week), PPT (SEIB after 3 weeks and US after 4 weeks), and CLF (SEIB after 4 weeks and US after 4 weeks) compared with baseline values. CONCLUSIONS: SEIB for 4 weeks has an effect similar to that of US for desensitizing myofascial pain and increasing joint flexibility. High accessibility and low cost would make SEIB a practical self-treatment method in elderly patients with myofascial pain syndrome.

Individualized feedback-based virtual reality exercise improves older women's self-perceived health: a randomized controlled trial.

OBJECTIVES: Individualized feedback-based virtual reality (IFVR) exercise is gaining attention as a cost-effective self-management strategy, however little is known about whether older adults themselves perceive IFVR exercise effective in improving their health. Therefore, we studied the effect of IFVR exercise on health-related quality of life (HRQoL) in older women. METHODS: Fifty-four older women aged ≥65 years were randomized to either IFVR exercise group (IFVRG, n=26) or group-based exercise group (GG, n=28). Both groups received a 60-min intervention three times a week for eight weeks. The Short-Form Health Survey (SF-36) was administered. To identify the possible placebo effect, 30-Second Chair Stand Test (30SCST), 8-Foot Up-and-Go Test (8FUGT), and 2-Minute Step Test (2MST) were also administered. RESULTS: intention-to-treat analysis with adjustment for baseline levels revealed that IFVRG showed greater improvement in mental health (p=0.029) and lower body strength (p=0.042), compared to GG. Within-group analysis for HRQoL revealed that IFVRG showed an increase in role-physical (p=0.015), bodily pain (p=0.017), general health (p=0.004), vitality (p=0.010), role-emotional (p=0.007), and mental health (p<0.001), whereas GG showed an increase in role-physical (p=0.022), general health (p=0.023), and social functioning (p = 0.023). Both groups showed an increase in 30SCST, 2MST and 8FUGT (all p<0.001). CONCLUSION: IFVR exercise improved HRQoL in older women, in addition to improving physical fitness. Therefore, it might be recommended to older women as an effective self-management strategy.

Comparison of the effects of water- and land-based exercises on the physical function and quality of life in community-dwelling elderly people with history of falling: a single-blind, randomized controlled trial.

PURPOSE: The purpose of this study was to identify the effects of water-based exercises on the physical functions and quality of life (QOL) in community-dwelling elderly people with history of falling. MATERIALS AND METHODS: Participants were randomly assigned to the water-based exercise group (n=34) or land-based exercise groups (n=32). To identify the effects on physical functions, muscle strength, flexibility, and mobility were measured. QOL and fear of falling were evaluated using the Short Form 36-item questionnaire and the modified falls efficacy scale (M-FES). The measurements were performed before and after the 10-week training period. RESULTS: Within-group analysis indicated that hip abduction and adduction strength improved significantly in both groups (p=0.005; p=0.007). However, no statistically significant within-group differences were found in the back scratch test (p=0.766) and chair sit-and-reach test (p=0.870). QOL was significantly different in both groups (health transition: p=0.014, physical functioning: p<0.001, role physical: p<0.001, role emotional: p=0.002, bodily pain: p<0.001, vitality: p<0.001, and mental health: p<0.001). There was a significant difference in the M-FES in both groups (p=0.040). CONCLUSIONS: These results indicate that water-based exercises are beneficial to improve the QOL, as well as physical activities, of community-dwelling elderly compared with land-based exercise. Water-based exercises would be useful to improve physical and psychological health in the elderly people with history of falling.

The hypoalgesic effect of remote tactile sensory modulation on the mechanical sensitivity of trigger points: A randomized controlled study.

BACKGROUND: Sensitivity of the myofascial trigger point (MTrP) can be inhibited by electrical stimulation of remote site. However, it remains unclear whether remote pain control of the MTrP occurs in the same spinal segment or in the supraspinal system. OBJECTIVES: The aims of this study were to identify whether the remote pain control occurs in the spinal segment corresponding to the MTrP or in the supraspinal system. METHODS: Test subjects (n = 10) received transcutaneous electrical nerve stimulation for 5 minutes, whereas control subjects (n = 10) received no intervention. The threshold for tactile sensory modulation at the lateral elbow was assessed using Von Frey filaments. The pressure sensitivities of MTrPs in both the infraspinatus and upper trapezius muscles were quantified by algometry. Measurements were performed at baseline and 1 and 15 minutes after the intervention. RESULTS: Increases of the tactile threshold at the remote site decreased the sensitivity of the MTrP innervated by same spinal segment. However, no changes were observed at MTrP sites innervated by contralateral fibers or those from different spinal segment. CONCLUSION: MTrP sensitivity is more strongly affected by interventions at remote ipsilateral sites in the same spinal segment than by stimulation of extra-segmental sites.
