BACKGROUND AND OBJECTIVE

Access to healthcare remains a challenge in most areas in the Philippines. Fifty-three percent (53%) of the Philippine population do not have access to a rural health unit (RHU) within a 30-minute travel t ime. As a response, the Department of Health (DOH) needs to construct an additional 2400 RHUs by 2025. This paper uses the Philippine Health Facility Development Plan 2020-2040 (PHFDP) as a reference to present a solution for locating sites for RHU placement in under-served areas using neural networks to meet the 30-minute travel time by maximizing population accessibility.

RHU accessibility was measured using geographic attributes as inputs to a back propagation neural network (BPNN) and a recurrent neural network (RNN): (1) land coverage and hazard data, representing geographical limitations; (2) population density and distribution, indicating demand for healthcare services; and (3) infrastructure-related features, such as road networks, points of interest, and the locations of existing RHUs, which influence healthcare accessibility. The models were trained to identify underserved areas and were implemented on a nationwide scale, excluding NCR, to locate candidate areas to increase population access to the new RHUs. The models were validated using a healthcare facility accessibility index (HCFAI) to assess RHU coverage improvement.

The BPNN showed stronger generalization across regions, achieving 79.1% average accuracy in distinguishing low from high accessible areas on Region 1 and identifying 1668 out of 3305 locations in the region as candidate sites. The RNN, better capturing unique regional characteristics, required separate training: 77.2% average accuracy on Region 1, identifying 1593 candidate sites. Our findings suggest expanding the use of land improves population access to healthcare facilities. Both models found more than the needed number of RHUs by 2040. The BPNN was more consistent than RNN to improve a region’s overall accessibility by increasing the HCFAI. The BPNN can increase population access to an RHU from 2.5-98.5% from its original population with access to an RHU.

The study demonstrates the usage of geographic attributes and neural networks to improve healthcare accessibility. The BPNN and RNN are adequate algorithms to find under-served areas and candidate sites for RHU construction to maximize population accessibility. The HCFAI metric validates the locations to highlight which neural network maximizes more of the region’s populat ion. The study contributes to ongoing efforts to improve healthcare infrastructure and accessibility, offering datadriven recommendations for RHU locations.

BACKGROUND

Low back pain is a major global cause of disability, typically treated through traditional onsite rehabilitation. However, the advancement of telerehabilitation during the COVID-19 pandemic presents an opportunity to examine its effectiveness as a treatment option for low back pain. This study aims to seek and explore the experiences and perspectives of healthcare professionals about onsite or online management of LBP.

The study will employ a phenomenological qualitative study design that will use quota sampling to recruit a total of 16 participants, equally distributed among rehabilitation doctors, physical therapists, barangay healthworkers, and patients with low back pain, coming from hospitals and centers affiliated with the University of Santo Tomas in Metro Manila. Key informant interviews that follow a semi-structured interview format will be conducted either on-site or online, depending on the preference of the invited informant. The NVivo data analysis software will be utilized to produce codes and outline themes from the gathered data.

The research is expected to highlight the nuanced interplay between individual viewpoints and contextual factors that influence decision-making in rehabilitation settings, besides identifying these themes. Findings will be instrumental in informing best practices for managing low back pain, thereby helping physical therapists determine the most effective treatment approach—whether through telerehabilitation or traditional on-site care. The study can provide actionable recommendations through grounding the implications of the analysis to the anticipated findings that might affect the rehabilitation practices and patient outcomes in the Philippines.

BACKGROUND AND OBJECTIVE

The Oswestry Disability Index (ODI)–English is a valid and reliable instrument for disability measurement in low back pain (LBP) patients. There is no existing ODI–Ilokano that evaluates LBP patients. This study aimed to cross-culturally adapt the ODI–English into Ilokano.

The ODI–English was cross-culturally adapted into Ilokano through a process that included forward translation, synthesis of the translations, back translation, expert committee review, and testing of the pre-final version.

Forward translation focused on capturing the essence of terms related to pain intensity, personal care, and daily activities, achieving consensus on phrases that accurately mirrored the original English meanings. Subsequent synthesis refined these translations, emphasizing idiomatic and conceptual equivalence over literal interpretations, particularly in nuanced areas like sleep disturbance and social life activities. Backward translation processes aligned Ilokano and English terms, especially for pain intensity and personal care, ensuring consistency across languages. The expert committee review addressed spelling, word choice, and sentence structure, making strategic adjustments for cultural relevance. Pilot testing with participants from Ilocos Norte and Ilocos Sur, Philippines highlighted comprehension challenges with specific terms, leading to adaptations like replacing 'milya' and 'yarda' with metric units and retaining culturally sensitive terms with supplementary English explanations.

This study refined the ODI–English into a culturally adapted Ilokano version, focusing on semantic, idiomatic, and cultural equivalence. Incorporating pilot testing feedback, such as modifying measurement units and addressing sensitive terms, highlighted the thorough adaptation process. The collaborative translation efforts and diverse patient input ensured a culturally resonant ODI version for Ilokano speakers. This adaptation enhances physical therapy practices by improving patient assessments and advocates for adapting patient-reported outcomes to diverse cultures, advancing patient-centered care.

OBJECTIVE: To observe the clinical efficacy of acupuncture combined with thunder-fire moxibustion in treating low back pain with cold-damp. METHODS: Seventy-two patients of low back pain with cold-damp were randomly divided into an observation group (36 cases, 1 case was eliminated) and a control group (36 cases, 1 case dropped out). The control group received acupuncture at Jizhong (GV6), Yaoyangguan (GV3), ashi points, bilateral Shenshu (BL23), Dachangshu (BL25), and Weizhong (BL40) for 30 min daily. The observation group was treated with thunder-fire moxibustion in addition to the same acupuncture regimen as the control group, once daily. Both groups were treated for 6 consecutive days followed by one rest day, for a total duration of 4 weeks. The visual analog scale (VAS) score, Oswestry disability index (ODI) score, Japanese Orthopedic Association (JOA) score, present pain intensity (PPI) score, and serum levels of β-endorphin (β-EP), 5-hydroxytryp tamin (5-HT), and substance P (SP) were compared before and after treatment, and the clinical efficacy was also compared between the two groups. RESULTS: Compared before treatment, the VAS scores, ODI scores, PPI scores, and serum levels of 5-HT and SP were decreased (P<0.01), while JOA scores and serum levels of β-EP were increased (P<0.01) in both groups after treatment. The observation group showed lower VAS, ODI, and PPI scores and serum levels of 5-HT and SP than those in the control group (P<0.05), as well as higher JOA score and serum level of β-EP (P<0.05). The total effective rate in the observation group was 94.3% (33/35), higher than 82.9% (29/35) in the control group (P<0.05). CONCLUSION Acupuncture combined with thunder-fire moxibustion could effectively alleviate pain and improve lumbar function in patients of low back pain with cold-damp, possibly by regulating β-EP, 5-HT, and SP levels.

OBJECTIVE: To compare the clinical efficacy of acupuncture with yin-yang regulation method versus local acupuncture in treating chronic low back pain (CLBP) in elderly patients with lumbar disc herniation (LDH), and to evaluate the changes in the multifidus muscle before and after treatment using musculoskeletal ultrasound. METHODS: A total of 128 elderly patients with CLBP due to LDH were randomly assigned to an observation group (64 cases, 2 cases dropped out) and a control group (64 cases, 2 cases dropped out). The control group received local acupuncture at bilateral L₃-L₅ Jiaji points (EX-B2), Shenshu (BL23), Dachangshu (BL25), Weizhong (BL40), Yaoyangguan (GV3), and ashi points. The observation group received acupuncture with yin-yang regulation method, which included an abdominal protocol with Baihui (GV20), Zhongwan (CV12), Qihai (CV6), Guanyuan (CV4), bilateral Tianshu (ST25), and Dahe (KI12), etc., and a lumbar protocol with Baihui (GV20), Dazhui (GV14), Jizhong (GV6), Yaoyangguan (GV3), and ashi points, etc., alternated bilaterally. Both groups were treated once every other day, three times per week, for a total of 12 sessions. The visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and the indexs of musculoskeletal ultrasound multifidus muscle (resting and functional thickness and Young's modulus values) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: After 1 and 4 weeks of treatment, both groups showed lower VAS scores compared to baseline (P<0.05), the VAS scores in the observation group were lower than those in the control group (P<0.001). ODI scores in both groups were decreased after 1 and 4 weeks of treatment compared to baseline (P<0.05), with a further reduction at 4 weeks of treatment compared to 1 week of treatment (P<0.05); the observation group showed lower ODI score than the control group after 1 week of treatment (P<0.001). After treatment, both groups demonstrated increased resting and functional multifidus muscle thickness bilaterally compared to baseline (P<0.01), with an increased right-side thickness change rate (P<0.01), though no significant difference was observed between groups (P>0.05). Compared to baseline, after treatment, the observation group exhibited decreased Young's modulus values for bilateral resting and functional multifidus muscle (P<0.01), while the control group showed reductions only in bilateral resting and right-side functional Young's modulus values (P<0.01). After treatment, the bilateral functional Young's modulus values in the observation group were lower than that in the control group (P<0.05), and the bilateral resting and functional changes in Young's modulus values were greater in the observation group than those in the control group (P<0.01). The overall effective rate was 93.5% (58/62) in the observation group, which was higher than 79.0% (49/62) in the control group (P<0.05). CONCLUSION Acupuncture with yin-yang regulation method effectively alleviates pain, improves functional disability, increases multifidus muscle thickness, and reduces Young's modulus values in elderly patients with CLBP due to LDH, which has superior therapeutic effect compared to local acupuncture.

OBJECTIVE: To observe the clinical effect of Fu's subcutaneous needling based on anatomy train theory for nonspecific low back pain (NLBP). METHODS: A total of 120 patients with NLBP were randomized into an anatomy train Fu's subcutaneous needling group (40 cases, 3 cases dropped out), a conventional acupuncture group (40 cases, 2 cases dropped out) and a conventional Fu's subcutaneous needling group (40 cases, 2 cases dropped out). Acupuncture was applied at ashi points and bilateral Shenshu (BL23) and Dachangshu (BL25) in the conventional acupuncture group, once every other day, 3 times a week. Fu's subcutaneous needling was applied at lumbodorsal myofascial trigger points (MTrPs) in the Fu's subcutaneous needling group, once every 3 days, twice a week. On the basis of the treatment in the Fu's subcutaneous needling group, Fu's subcutaneous needling was applied at MTrPs along the posterior superficial line and lateral line in the anatomy train Fu's subcutaneous needling group, once every 3 days, twice a week. All groups were treated for 2 weeks. Before and after treatment, the scores of numeric rating scale (NRS) and Oswestry disability index (ODI) were observed, the distance of Schober test was measured and the endurance of trunk extensors was assessed in the 3 groups. RESULTS: After treatment, in the 3 groups, the NRS and ODI scores were decreased compared with those before treatment (P<0.05), the Schober test distance was increased compared with that before treatment (P<0.05), the static and dynamic muscle endurance was increased compared with that before treatment (P<0.05). After treatment, in the anatomy train Fu's subcutaneous needling group, the NRS and ODI scores were lower than those in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05), the Schober test distance was longer than that in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05), the static and dynamic muscle endurance was superior to that in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05). CONCLUSION Fu's subcutaneous needling based on anatomy train theory can effectively relieve the pain symptom, enhance quality of life, improve lumbar motion and lumbar muscle function in patients with NLBP.

OBJECTIVE: To compare the clinical efficacy between thermo-electroacupuncture at yaosanzhen and oral celecoxib in the treatment of chronic lumbar muscle strain with cold dampness. METHODS: A total of 80 patients with chronic lumbar muscle strain of cold dampness were randomly divided into an observation group (40 cases, 1 case dropped out) and a control group (40 cases, 2 cases were excluded). The observation group was treated with thermo-electroacupuncture at yaosanzhen (bilateral Shenshu [BL23], Dachangshu [BL25], Weizhong [BL40]), disperse-dense wave was selected, with a pulse cycle of 0.08 s, current intensity of 1-3 mA, with needles heated to approximately 45 ℃, the duration was 25 min per session, once a day. The control group was given oral celecoxib capsules, once daily, 200 mg each time. Six sessions as one course, with a 1-day interval between courses, 2 courses were required in both groups. The TCM syndrome score, visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and Japanese Orthopedic Association (JOA) score before and after treatment in both groups were compared. The serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), thromboxane B2 (TXB2) and C-reactive protein (CRP) were detected using ELISA method before and after treatment in both groups. The clinical efficacy was evaluated in both groups after treatment. RESULTS: After treatment, the TCM syndrome scores, VAS scores, ODI scores and serum levels of TNF-α, IL-6, TXB2, CRP in both groups were reduced compared with those before treatment (P<0.01), while the JOA scores were increased (P<0.01)；the TCM syndrome score, VAS score, ODI score and serum levels of TNF-α, IL-6, TXB2, CRP in the observation group were lower than those in the control group (P<0.01, P<0.05), and the JOA score was higher than that in the control group (P<0.01). The total effective rate of the observation group was 92.3% (36/39), which was superior to 78.9% (30/38) in the control group (P<0.05). CONCLUSION Thermo-electroacupuncture at yaosanzhen can alleviate pain symptom in patients with chronic lumbar muscle strain of cold dampness, regulate lumbar function, reduce the levels of inflammatory factors, and the therapeutic effect is superior to oral celecoxib.

OBJECTIVE: To explore the pain-location interaction between pressure-sensitive points on the body surface and traditional acupoints in patients with chronic non-specific low back pain (CNLBP) under different disease courses, using Euclidean distance and multivariate statistical analysis. METHODS: A pressure-sensitive point detection was performed on 30 CNLBP patients with varying disease courses. A constant pressure was applied using an FDK20 algometer within a designated lumbar area, a total of 50 points were tested, and the tested points were numbered; the visual analogue scale (VAS) pain score was recorded simultaneously. MatlabR2022a9.12. software was used to extract the positions of pressure-sensitive points, and preprocessing and normalization of point location and VAS scores data were conducted. Under constraint conditions (VAS≥8.0 ∩ Euclidean distance to acupoint≤0.5), the proportion of pressure-sensitive points within the Euclidean distance threshold to each acupoint (PVD_acupoint) was calculated, followed by multivariate statistical analysis. RESULTS: ①Constrained analysis of PVD_acupoint showed that PVD_{Qihaishu (BL24)} and PVD_{Dachangshu (BL25)} were positively correlated with disease course (r=0.55, P<0.01). ②Factor analysis and silhouette analysis revealed that PVD_{Shenshu (BL23)} and PVD_{Dachangshu (BL25)} exhibited trends consistent with disease course progression (P>0.05), with different degree (P<0.01). CONCLUSION The PVD_acupoint value based on Euclidean distance can characterize the pressure sensitivity features of traditional acupoints associated with disease. Multivariate statistical analysis of PVD_acupoint confirms that selecting the acupoint combination of Shenshu (BL23) and Dachangshu (BL25) for CNLBP is associated with the distribution of surrounding pressure-sensitive points and the pathological characteristics of the condition.
