Improved gait speed in spastic paraplegia: a new modality

Gait analysis patterns and rehabilitative interventions to improve gait in persons with hereditary spastic paraplegia: a systematic review and meta-analysis

Background

Hereditary spastic paraplegias (HSPs) are a group of inheritance diseases resulting in gait abnormalities, which may be detected using instrumented gait analysis. The aim of this systematic review was 2-fold: to identify specific gait analysis patterns and interventions improving gait in HSP subjects.

Methods

A systematic review was conducted in PubMed, Cochrane Library, REHABDATA, and PEDro databases, in accordance with reporting guidelines of PRISMA statement and Cochrane's recommendation. The review protocol was recorded on the PROSPERO register. Patients with pure and complicated HSP of any age were included. All types of studies were included. Risk of bias, quality assessment, and meta-analysis were performed.

Results

Forty-two studies were included: 19 were related to gait analysis patterns, and 24 were intervention studies. The latter ones were limited to adults. HSP gait patterns were similar to cerebral palsy in younger subjects and stroke in adults. Knee hyperextension, reduced range of motion at knee, ankle, and hip, reduced foot lift, and increased rapid trunk and arm movements were reported. Botulinum injections reduced spasticity but uncovered weakness and improved gait velocity at follow-up. Weak evidence supported intrathecal baclofen, active intensive physical therapy (i.e., robot-assisted gait training, functional exercises, and hydrotherapy), and functional electrical stimulation. Some improvements but adverse events were reported after transcranial magnetic stimulation, transcutaneous spinal direct current stimulation, and spinal cord stimulation implant.

Conclusion

Knee hyperextension, non-sagittal pelvic movements, and reduced ROM at the knee, ankle, and hip represent the most peculiar patterns in HSP, compared to diplegic cerebral palsy and stroke. Botulinum improved comfortable gait velocity after 2 months. Nonetheless, interventions reducing spasticity might result in ineffective functional outcomes unveiling weakness. Intensive active physical therapy and FES might improve gait velocity in the very short term.

Individual perception of environmental factors that influence lower limbs spasticity in inherited spastic paraparesis

BACKGROUND

Phenotypic variability is a consistent finding in neurogenetics and therefore applicable to hereditary spastic paraparesis. Identifying reasons for this variability is a challenge. We hypothesized that, in addition to genetic modifiers, extrinsic factors influence variability.

OBJECTIVES

Our aim was to describe the clinical variability in hereditary spastic paraparesis from the person's perspective. Our goals were to identify individual and environmental factors that influence muscle tone disorders and derive interventions which could improve spasticity.

METHODS

This study was based on self-assessments with questions on nominal and ordinal scales completed by participants with hereditary spastic paraparesis. A questionnaire was completed either in-person in the clinic or electronically via lay organization websites.

RESULTS

Among the 325 responders, most had SPG4/SPAST (n = 182, 56%) with a mean age at onset of 31.7 (SD 16.7) years and a mean disease duration of 23 (SD 13.6) years at the time of participation. The 2 factors identified as improving spasticity for > 50% of the responders were physiotherapy (193/325, 59%), and superficial warming (172/308, 55%). Half of the responders (n = 164, 50%) performed physical activity at least once a month and up to once a week. Participants who reported physiotherapy as effective were significantly more satisfied with ≥ 3 sessions per week. Psychologically stressful situations (246/319, 77%) and cold temperatures (202/319, 63%) exacerbated spasticity for most participants.

CONCLUSION

Participants perceived that physiotherapy reduced spasticity and that the impact of physiotherapy on spasticity was much greater than other medical interventions. Therefore, people should be encouraged to practice physical activity at least 3 times per week. This study reported participants' opinions: in hereditary spastic paraparesis only functional treatments exist, therefore the participant's expertise is of particular importance.

Analgesic effects of combined transversus abdominis plane block and intramuscular electrical stimulation in patients undergoing cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy: a randomized controlled trial

BACKGROUND

To evaluate the analgesic efficacy of a four-quadrant transversus abdominis plane (4QTAP) block and a combination of 4QTAP block with needle electrical twitch and intramuscular electrical stimulation (NETOIMS) in patients undergoing cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC).

MATERIALS AND METHODS

Eighty-one patients who underwent CRS followed by HIPEC were included in this study. Patients were randomly assigned to one of three groups: group 1 (intravenous patient-controlled analgesia, control group), group 2 (preoperative 4QTAP block), and group 3 (preoperative 4QTAP block and postoperative NETOIMS). The primary study endpoint was the pain score assessed by the visual analog scale (VAS: 0, no pain; 10, worst imaginable pain) on postoperative day (POD) 1.

RESULTS

The VAS pain score on POD 1 was significantly lower in group 2 than in group 1 (6.0±1.7 and 7.6±1.9, P =0.004), whereas that in group 3 was significantly lower than that in groups 1 and 2 ( P <0.001 and P =0.004, respectively). Opioid consumption and nausea and vomiting incidence during POD 7 were significantly lower in group 3 than in groups 1 and 2. Gait speed and peak cough flow on POD 4 and 7, as well as the quality of recovery (QoR)-40 score on POD 4, were significantly higher in group 3 than in groups 1 and 2.

CONCLUSIONS

The combination of a 4QTAP block with NETOIMS provided more effective analgesia than a 4QTAP block alone after CRS, followed by HIPEC, and enhanced functional restoration and quality of recovery.

A novel mutation in the UBAP1 gene causing hereditary spastic paraplegia: A case report and overview of the genotype-phenotype correlation

Hereditary Spastic Paraplegia (HSP) is considered to be one of the common neurodegenerative diseases with marked genetic heterogeneity. Recently, the mutations in ubiquitin-associated protein 1 (UBAP1) have been described in patients with HSP, known as spastic paraplegias 80 (SPG80). Here, we reported a Chinese HSP family presenting a frameshift mutation in the UBAP1 gene leading to complex HSP. Their clinical features encompassed spastic paraparetic gait, exaggerated patellar tendon reflexes, bilateral Babinski signs, and hyperactive Achilles tendon reflex. The proband also had severe urinary incontinence and a dermoid cyst at the lumbar 4–5 spinal cord, which rarely occurs in HSP patients. Following whole-exome sequencing, a novel heterozygous mutation (c.437dupG, NM_016,525) was identified in the UBAP1 that segregated with the family’s phenotype and resulted in truncating UBAP1 protein (p.Ser146ArgfsTer13). Moreover, we reviewed the genotypes of UBAP1 and the phenotypic variability in 90 HSP patients reported in the literature. We found that the age of onset in UBAP1-related patients was juvenile, and there were population differences in the age of onset. The main complications were lower extremity spasticity, hyperreflexia, and the Babinski sign. Exon 4 of UBAP1 was identified as a mutation hotspot region. Our study expands the knowledge of UBAP1 mutations, which will aid in HSP patient counseling. Further molecular biological research is needed to explore the genotype-phenotype correlations of UBAP1-related HSP.

Effectiveness of Intramuscular Electrical Stimulation on Postsurgical Nociceptive Pain for Patients Undergoing Open Pancreaticoduodenectomy: A Randomized Clinical Trial

BACKGROUND

After pylorus-preserving pancreaticoduodenectomy (PPPD), incision and suture of the abdominal muscles cause inflammatory changes and elicit somatic pain that deteriorates the quality of life. There have been no previous reports on needle electrical twitch obtaining intramuscular stimulation (NETOIMS) in abdominal open operation; this study aimed to apply NETOIMS for postoperative somatic pain in patients undergoing PPPD as a new treatment modality for pain control.

METHODS

Between June 2018 and January 2019, 44 patients who underwent PPPD were randomly assigned to a control group and the NETOIMS group. The NETOIMS group received NETOIMS in the transverse abdominis muscle under ultrasound guidance right after operation under general anesthesia. The pain score (visual analog scale), peak cough flow (PCF), and gait speed were repetitively measured from 1 day before operation to 2 weeks after discharge as scheduled. Data were analyzed by the linear mixed model and repeated-measures analysis of variance.

RESULTS

Of the 44 patients recruited, data from 38 patients were finally analyzed. The pain scores were significantly lower in the NETOIMS group after PPPD (p = 0.01). Although the PCF at each measuring time point did not show inter-group difference (p = 0.20), improvement of PCF from the second day after operation to discharge was greater (p = 0.02) and gait speed improved significantly faster (p < 0.01) in the NETOIMS group than in the control group.

CONCLUSIONS

NETOIMS helps in rapid reduction of postoperative somatic pain developed after PPPD and in improvement of PCF and gait speed.
