Use of standardised outcome measures among physiotherapists in French-speaking sub-Saharan Africa.

Background: The use of standardised assessment tools is a fundamental aspect of good clinical practice. However, to our knowledge, no study has documented the use of standardised assessment tools in physiotherapy in French-speaking sub-Saharan Africa. Objectives: Documenting the use of standardised outcome measures in physiotherapy in French-speaking sub-Saharan Africa. Method: Our cross-sectional survey used an online self-questionnaire on facilitators and barriers to the use of standardised outcome measures, distributed to physiotherapists in French-speaking sub-Saharan Africa. Results: A total of 241 physiotherapists working in French-speaking sub-Saharan Africa responded to the survey. The most represented countries were Benin (36.9%), Cameroon (14.1%), and Burkina Faso (10.8%). Although 99% of participants reported using standardised outcome measures, only 27% of the respondents used them systematically (all the time). The most reported facilitators included the recognition that standardised outcome measures help to determine whether treatment is effective, help to guide care, and improve communication with patients. The most significant barriers were the lack of time, unavailability of the standardised outcome measures, and non-sensitivity of measures to patients' cultural and ethnic concerns. There was a higher proportion of use in the middle age group (30-40) (p = 0.02) and a lower proportion of use in physiotherapists simultaneously working in public and private sectors (p = 0.05). Conclusion: Standardised outcome measures are still not widely used by physiotherapists in French-speaking sub-Saharan Africa. Clinical implications: The perceived barriers and facilitators could help to develop strategies to improve the systematic use of outcome measures in French-speaking sub-Saharan Africa.

Visual feedback and age affect upper limb reaching accuracy and kinematics in immersive virtual reality among healthy adults.

This cross-sectional study aimed to evaluate the effect of visual feedback, age and movement repetition on the upper limb (UL) accuracy and kinematics during a reaching task in immersive virtual reality (VR). Fifty-one healthy participants were asked to perform 25 trials of a reaching task in immersive VR with and without visual feedback of their hand. They were instructed to place, as accurately and as fast as possible, a controller held in their non-dominant hand in the centre of a virtual red cube of 3 cm side length. For each trial, the end-point error (distance between the tip of the controller and the centre of the cube), a coefficient of linearity (CL), the movement time (MT), and the spectral arc length of the velocity signal (SPARC), which is a movement smoothness index, were calculated. Multivariate analyses of variance were conducted to assess the influence of visual feedback, age and trial repetition on the average end-point error, SPARC, CL and MT, and their time course throughout the 25 trials. Providing visual feedback of the hand reduced average end-point error ( P  < 0.001) and MT ( P  = 0.044), improved SPARC ( P  < 0.001) but did not affect CL ( P  = 0.07). Younger participants obtained a lower mean end-point error ( P  = 0.037), a higher SPARC ( P  = 0.021) and CL ( P  = 0.013). MT was not affected by age ( P  = 0.671). Trial repetition increased SPARC ( P  < 0.001) and CL ( P  < 0.001), and reduced MT ( P  = 0.001) but did not affect end-point error ( P  = 0.608). In conclusion, the results of this study demonstrated that providing visual feedback of the hand and being younger improves UL accuracy and movement smoothness in immersive VR. UL kinematics but not accuracy can be improved with more trial repetitions. These findings could guide the future development of protocols in clinical rehabilitation and research.

Is cognition considered in post-stroke upper limb robot-assisted therapy trials? A brief systematic review.

The aim of this systematic review was, first, to determine whether or not individuals with cognitive deficits after stroke were enrolled in trials that investigated upper limb robot-assisted therapy effectiveness, and, second, whether these trials measured cognitive outcomes. We retrieved 6 relevant systematic reviews covering, altogether, 66 articles and 2214 participants. Among these 66 clinical trials, only 10 (15%) enrolled stroke participants with impaired cognition, whereas 50 (76%) excluded those with impaired cognition. The remaining six trials (9%) were classified as unclear as they either excluded individuals unable to understand simple instructions or did not specify if those with cognitive disorders were included. Furthermore, only 5 trials (8%) used cognitive measures as outcomes. This review highlights a lack of consideration for individuals with cognitive impairments in upper limb robotic trials after stroke. However, cognition is important for complex motor relearning processes and should not be ignored.
