Effect of transcutaneous spinal direct current stimulation on spasticity in upper motor neuron conditions: a systematic review and meta-analysis.

STUDY DESIGN: A systematic review and meta-analysis of clinical trials. OBJECTIVES: To determine the effect of non-invasive transcutaneous spinal direct current stimulation (tsDCS) on spasticity, activity limitations and participation restrictions in various upper motor neuron diseases. METHODS: Six databases including CINAHL plus, Cochrane CENTRAL, Embase, MEDLINE, SCOPUS and Web of Science were searched for the relevant records from January 2008 to December 2022. Two reviewers independently selected and extracted data on spasticity, activity limitations and participation restrictions. The risk of bias was evaluated using the PEDro scale while the GRADE approach established the certainty of the evidence. RESULTS: Eleven studies were identified of which 5 (45.5%) were rated as having a low risk of bias and 8 (72.7%) were meta-analyzed. The meta-analyses did not show any significant differences between cathodal (SMD = -0.67, 95% CI = -1.50 to 0.15, P = 0.11, I2 = 75%, 6 RCTs) or anodal (SMD = 0.11, 95% CI = -0.43 to -0.64, p = 0.69, I2 = 0%, 2 RCTs) and sham tsDCS for spasticity. There was also no significant difference between active and sham tsDCS for activity limitations (SMD = -0.42, 95% CI = -0.04 to 0.21, p = 0.2, I2 = 0%, 2 RCTs) and participation restrictions (MD = -8.10, 95% CI = -18.02 to 1.82, p = 0.11, 1 RCT). CONCLUSIONS: The meta-analysis of the available evidence provides an uncertain estimate of the effect of cathodal tsDCS on spasticity, activity limitation and participation restriction. It might be very helpful, or it may make no difference at all. However, considering the level of the evidence and the limitation in the quality of the majority of the included studies, further well-designed research may likely change the estimate of effect.

Knowledge, awareness and use of current practice of palliative care amongst physiotherapists.

Background: Recently, there has been a marked increase in the incidence of cancer, HIV, and other noncommunicable diseases globally. Thus, the demand for palliative care (PC), including end-of-life care, continues to grow worldwide. Physiotherapy has an important role in PC as it aims to alleviate symptoms and improve quality of life by optimising independent levels of function. Objective: To assess the level of knowledge, awareness and current practice of PC amongst Nigerian physiotherapists in clinical practice. Method: Our study used a cross-sectional descriptive census-based method and recruited practising physiotherapists in Nigeria. An electronic questionnaire was used to collect data over 12 weeks, comprising 36 semistructured questions in four domains: personal information, knowledge, awareness and current practices regarding PC. Data were analysed using a pragmatist paradigm. Results: Of the 426 physiotherapists who participated, 50% (n = 213) had a postgraduate degree, 49.5% (n = 211) had a bachelor's degree and 0.5% (n = 2) had a Doctor of Physical Therapy degree. The results also indicate that 73.9% (n = 315) of the participants had sufficient knowledge about PC, 80.5% (n = 343) had a sufficient level of awareness about PC and 66.7% (n = 284) were using current clinical practices in the rehabilitation of critically ill patients or those with chronic conditions. Conclusion: It was concluded that most Nigerian physiotherapists had sufficient knowledge and awareness about PC and were involved in the management of patients requiring PC physiotherapy. Clinical implication: It can be understood that a large proportion of Nigerian physiotherapists have clinical experience managing patients requiring PC, despite inadequate formal training in this field.

Prevalence of psychological symptoms and their correlates among physiotherapy clinical students: A cross-sectional study.

Background: Mental health in medical students is well researched, with physiotherapy students receiving less attention even though psychiatry is a recognised specialty within physiotherapy. Objectives: To assess the prevalence and correlates of depression, anxiety and stress among physiotherapy clinical students. Methods: A descriptive cross-sectional study design was employed on 402 physiotherapy clinical students aged 17-40 years using a convenience sampling method. The data were collected using the self-administered 42-items Depression, Anxiety and Stress scale (DASS) and the data were analysed using a Chi-square test and binary logistic regression analysis. Results: The prevalence of depression, anxiety and stress among these students was 79.9%, 85.6% and 81.6%, respectively. The results indicate that financial status and social life influenced depression by 20.6% (odds ratio [OR] [95%] = 1.206 [1.110, 1.311]) and 36% (OR [95%] = 1.360 [1.050, 1.764]), respectively. Fear of repeating a class influenced anxiety by eight times (OR [95%] = 8.330 [6.643, 10.422]). Fear of repeating a class, financial status and academic performance influenced stress by eight times (OR [95%] = 8.360 [6.677, 10.470]), 17.5% (OR [95%] = 1.175 [1.083, 1.275]) and 18.1% (OR [95%] = 1.181 [1.083, 1.276]), respectively. Conclusion: Our study concluded that there was a high prevalence of depression, anxiety and stress among physiotherapy clinical students. These outcomes suggest that more attention needs to be given to improving physiotherapy clinical students' mental health, which will ultimately improve learning outcomes. Clinical implications: The long-term effects of psychological distress could potentially impact students' academic performance. It may also have long-lasting effects after graduation. Therefore, students who are at risk of developing psychological symptoms are needed to be thoroughly examined and then receive early required interventions.

Strength exercise for balance and gait in HIV-associated distal symmetrical polyneuropathy: A randomised controlled trial.

BACKGROUND: HIV-associated peripheral neuropathy (PN) is a common neurological complication associated with HIV infection. Distal symmetrical polyneuropathy (DSPN) is the most commonly occurring type, which is associated with symptoms such as numbness, unsteady gait and, in some cases, muscle atrophy and weakness when myelinated nerve fibres are affected. If unmyelinated nerve fibres are affected, a painful neuropathy and autonomic symptoms may occur. OBJECTIVES: This research study assessed the effects of a strength exercise intervention on balance impairment and gait disturbance amongst individuals living with HIV-associated DSPN. METHOD: The study was a single-blinded, randomised controlled trial (RCT) with participants sourced from four HIV centres in Kano metropolis, Nigeria. The intervention was supervised and included progressive resistance exercise (PRE) (three 40-min sessions per week for 12 weeks) using a quadriceps bench (n = 44). The control group (CG) included the non-exercise group (n = 47). The two groups continued to receive routine care. Data were summarised and analysed using inferential statistics (SPSS version 20 program) with the alpha level set at < 0.05. RESULTS: At 12 weeks, the results revealed significant improvement with regard to balance performance (p = 0.001) and walking ability (p = 0.001) in the training group. In contrast, no significant differences in balance (P = 0.677) or gait (P = 0.578) were observed in the CG. CONCLUSION: The findings suggest that PRE is beneficial for balance impairment and gait disturbance caused by neuropathy in persons living with HIV and receiving antiretroviral drugs.

Two manual therapy techniques for management of lumbar radiculopathy: a randomized clinical trial.

CONTEXT: Evidence has shown that spinal mobilization with leg movement (SMWLM) and progressive inhibition of neuromuscular structures (PINS) are individually effective in the management of lumbar radiculopathy. However, previous evidence reported data for only a short-term study period and did not investigate the effect of the combined manual therapy techniques. OBJECTIVES: To compare the combined effects of two manual therapy techniques (SMWLM and PINS) with the individual techniques alone (SMWLM or PINS) in the management of individuals with lumbar radiculopathy. METHODS: A total of 60 patients diagnosed with unilateral lumbar radiculopathy secondary to disc herniation were randomly allocated into three groups: 20 participants each in the SMWLM, PINS, and combined SMWLM + PINS groups. Each group attended two treatments per week for 30 min each, for three months. Participants were assessed at baseline, immediately posttreatment, and then at three, six, and nine months follow-up using the Visual Analog Scale (VAS), Rolland-Morris Disability Questionnaire (RMDQ), and Sciatica Bothersomeness Index (SBI). RESULTS: Between-groups analyses using a two-way repeated-measures analysis of variance indicated significant interactions between groups and follow-up times for all outcomes (p=0.001). Participants receiving combined SMWLM + PINS treatment experienced greater improvement in leg pain, back pain, disability, and sciatica at all timelines (immediately posttreatment, and three, six, and nine months follow-up) than the participants receiving SMWLM or PINS alone (p<0.05). However, participants receiving SMWLM alone showed better improvement than the participants receiving PINS alone at all timelines (p<0.05). CONCLUSIONS: A combined SMWLM + PINS treatment protocol showed greater improvement than the individual techniques alone in the management of individuals with LR in this study.

Effect of integrated neuromuscular inhibition technique compared with positional release technique in the management of piriformis syndrome.

CONTEXT: Studies have indicated that the muscle energy technique (MET) and the positional release technique (PRT) are effective in the management of piriformis syndrome (PS); however, evidence is scarce regarding the combination of these techniques in the form of an integrated neuromuscular inhibition technique (INIT) in the management of individuals with PS. Although a previous trial investigated the effect of INIT for PS, that study did not integrate Ruddy's reciprocal antagonist facilitation (RRAF) method into the INIT protocol, nor did the authors diagnose PS according to established criteria. OBJECTIVES: To examine the effects of INIT with integrated RRAF compared with PRT in the management of patients diagnosed with PS. METHODS: This study was designed as a single blind randomized clinical trial in which participants diagnosed with PS were randomly allocated into INIT and PRT groups. Each group attended two treatment sessions per week for 8 weeks. Patients in the INIT group received a protocol in which the patient's tender point or trigger point was palpated in the belly of the piriformis approximately halfway between the inferior lateral angle of the sacrum and the greater trochanter, at which point the therapist applied an intermittent or sustained pressure and maintained the pressure for 20-60 seconds (depending on the participant's response to pain reduction). For INIT patients, that protocol was also followed by RRAF, a method in which a patient introduces a series of tiny/miniature contractions or efforts (20 times per 10 seconds) against a therapist's resistance. Patients in the PRT group were treated by palpating the same trigger point described in the INIT group, followed by application of light pressure at the location of the trigger point, which was maintained the pressure for 2 minutes or until the pain subsided (determined by asking the participant to report a pain score using a visual analog scale at 30 second intervals). For both groups, three repetitions of the INIT or PRT treatment were performed over 10 minutes at each clinical visit. Additionally, each group also received stretching exercises immediately after the INIT or PRT treatment session. Each participant was assessed at baseline, immediately posttreatment, and at 4 months posttreatment for pain, sciatica, functional mobility, quality of life, hip abduction, and internal rotation. A repeated measures analysis of variance (ANOVA) of within-between group interactions was used to analyze the treatment effect. RESULTS: Forty eight participants (age range, 25-47 years; mean age ± standard deviation, 32.81 ± 3.27 years) were randomized into the INIT and PRT groups, with 24 participants in each group. No significant between-group differences (p>0.05) were observed in the baseline demographic and clinical variables of the participants. A repeated-measures ANOVA indicated that there was a significant time effect for all outcomes, with a significant interaction between time and intervention (p<0.001). The Bonferroni post hoc analyses of time and intervention effects indicated that the INIT group improved significantly compared with the PRT group in all outcomes (p<0.05) immediately posttreatment and at the 4 months follow up period. CONCLUSIONS: INIT was more effective than PRT in the management of individuals with PS. It should be noted the significant improvement achieved in both the groups may have also been contributed to by the stretching exercises that were used as adjunct therapies by both groups.

Assessment of family needs of children with cerebral palsy in Northern-Nigeria: A cross-sectional study.

PURPOSE: This study aimed to identify the needs and priorities of parents of children with cerebral palsy (CP) in order to improve care by increasing family participation in rehabilitation programmes. METHODS: This cross-sectional questionnaire-based study was conducted between January to March 2019. Convenience sampling was used to recruit 43 family members (18 years and above) of children with CP who came to the physiotherapy departments for rehabilitation services for their children. Fisher's exact test was used to analyse the association between socio-demographic characteristics and each of the need items. RESULTS: Five different items were identified to be the family needs that were most frequently met: a) 'need for active involvement in the child's treatment and therapies' (n= 40; 93.0%), b) 'need for the provision of standard medical care (n= 39; 90.7%), c) 'need for questions to be answered honestly' (n= 38; 88.4%), d) 'need for healthcare professionals to respect the child's wishes' (n= 36; 83.7%), e) 'need for mothers to discuss their feelings (depression, stress etc.) with someone who has similar experience' (n= 36; 83.7%). Conversely, three items were the most unmet family needs: a) 'need to have professionals to consult whenever the child needs help' (n= 39; 90.7%), b) 'need to be informed about the child's prognosis' (n= 41; 95.3%), and c) 'need to have financial support to provide the child with adequate care' (n= 43; 100%). CONCLUSION: All participants overwhelmingly reported that their financial needs were their highest priority. The multiple needs of families of children with disabilities must be assessed and considered in rehabilitation services when treating children with CP.
