Impact of rehabilitation on volumetric muscle loss in subjects with traumatic spinal cord injury: A systematic review

Efficacy of neuromodulation and rehabilitation approaches on pain relief in patients with spinal cord injury: a systematic review and meta-analysis

INTRODUCTION

Spinal cord injury (SCI) is a debilitating neurological condition that causes physical dependency, psychological distress, and financial burden. Pain is a common consequence of SCI, significantly impacting quality of life. Effective pain management in SCI is challenging and requires multifaceted approaches. Among rehabilitation methods, non-invasive brain stimulation techniques such as repetitive transcranial magnetic stimulation (rTMS), theta burst stimulation (TBS), transcranial direct current stimulation (tDCS), transcutaneous electrical nerve stimulation (TENS), and virtual reality (VR) have been explored. This study aims to evaluate the efficacy of rehabilitation and non-invasive brain stimulation techniques on pain relief in SCI patients.

METHODS

A systematic review of the literature was conducted using PubMed, Scopus, and ScienceDirect with the formula ("spinal cord injury") AND ("pain"). Risk of bias was assessed using the Cochrane Risk of Bias Tool.

RESULTS

Sixteen studies involving 319 patients were included. Patients in the control groups received: rTMS in seven trials, tDCS in seven trials, TBS in one trial, and TENS combined with VR in one trial. The trials analyzed were of poor methodological quality, characterized by small sample sizes, weak power analyses, varying clinical scores, and non-comparable follow-up periods. No major complications or serious adverse events were reported.

CONCLUSION

Results were inconsistent, with no solid evidence supporting the superiority of rehabilitation techniques over comparator treatments. However, the favorable safety profile and positive outcomes in some measures suggest potential benefits for pain management and quality of life. Further studies are necessary to better understand SCI-related pain and optimize treatment strategies.

Electrotherapy in stroke rehabilitation can improve lower limb muscle characteristics: a systematic review and meta-analysis

PURPOSE

This review assesses the effect of electrotherapy (e.g. functional electrical stimulation (FES), motor and sensor therapeutic electrical stimulation (TES)) on muscle strength and skeletal muscle characteristics in individuals post-stroke compared to conventional or sham therapy.

METHODS

A systematic literature search was conducted in MEDLINE, SCOPUS, and Web of Science, focusing on randomized controlled trials investigating the effect of electrotherapy. Data of interest was extracted from eligible studies, and risk of bias was assessed.

RESULTS

In total, 23 studies (933 people post-stroke) were included, of which 17, which mainly focus on patients in a chronic stage of stroke recovery and the implementation of FES, were incorporated in the meta-analysis. A significant increase in muscle strength was found favoring electrotherapy over conventional therapy (SMD 0.63, 95% CI 0.34-0.91, I2 = 37%, p = 0.07) and over sham therapy (SMD 0.44, 95% CI 0.20-0.68, I2 = 38%, p = 0.08). Three studies investigated the effect on muscle thickness and found a significant increase in favor of electrostimulation when compared to conventional therapy (MD 0.11 cm, 95% CI 0.06-0.16, I2 = 0%, p = 0.50).

CONCLUSION

Current evidence suggests electrotherapy in combination with physiotherapy has positive effects on lower limb muscle strength and skeletal muscle characteristics in patients recovering from stroke.

Long-Term Impact of Deep Brain Stimulation in Parkinson's Disease: Does It Affect Rehabilitation Outcomes?

Background and Objectives: Although the growing literature is now focusing on the long-term effects of Deep Brain Stimulation (DBS) in Parkinson's disease (PD), there is still a large gap of knowledge about its long-term implications in rehabilitation. Therefore, this study aimed at investigating the effects of rehabilitation in PD patients years after DBS implantation. Materials and Methods: This retrospective case-control study analyzed records from Moriggia-Pelascini Hospital, Italy from September 2022 to January 2024. Data of PD patients (n = 47) with (DBS group, n = 22) and without (control group, n = 25) DBS were considered. All study participants underwent a daily rehabilitation program lasting four weeks, including warm-up, aerobic exercises, strength training, postural exercises, and proprioceptive activities. The outcomes assessed were the Unified Parkinson's Disease Rating Scale (UPDRS), Berg Balance Scale (BBS), Timed Up and Go (TUG), 6 Min Walk Test (6MWT), and Self-Assessment Parkinson Disease Scale (SPDDS). Results: DBS group showed significant improvements in terms of all outcome measures after the rehabilitation intervention (UPDRS III: -7.0 (-11.5 to -1.0); p = 0.001; UPDRS I II IV: -12.0 (-19.0 to -4.5); p = 0.001; BBS: 7.0 (3.8 to 10.3); p < 0.001; TUG (s): -2.8 (-5.7 to -1.1); p < 0.001; SPDDS: -8 (-13.0 to -4.0); p < 0.001; 6MWT (m): 81 (37.3 to 132.3); p < 0.001). No differences were reported in the between-group analysis (p: NS). Conclusions: This study emphasizes positive rehabilitation effects on PD patients irrespective of DBS status. Further research is essential to elucidate long-term effects of DBS on rehabilitation outcomes of PD patients.
